twitter.android: fix get_own_user_id for latest exports

once XML files increase past a certain size
(was about 220MB for me), the parser just throws
an error because the tree is too large (iirc for
security reasons)

could maybe look at using iterparse in the future
to parse it without loading the whole file, but this
seems to fix it fine for me

+For code reference, see: [`my.core.denylist.py`](../my/core/denylist.py)
+
+A helper module for defining denylists for sources programmatically (in layman's terms, this lets you remove some particular output from a module you don't want)
+
+Lets you specify a class, an attribute to match on,
+and a JSON file containing a list of values to deny/filter out
+
+As an example, this will use the `my.ip` module, as filtering incorrect IPs was the original use case for this module:
+
+```python
+class IP(NamedTuple):
+    addr: str
+    dt: datetime
+```
+
+A possible denylist file would contain:
+
+```json
+[
+    {
+        "addr": "192.168.1.1",
+    },
+    {
+        "dt": "2020-06-02T03:12:00+00:00",
+    }
+]
+```
+
+Note that if the value being compared to is not a single (non-array/object) JSON primitive
+(str, int, float, bool, None), it will be converted to a string before comparison
+
+To use this in code:
+
+```python
+from my.ip.all import ips
+filtered = DenyList("~/data/ip_denylist.json").filter(ips())
+```
+
+To add items to the denylist, in python (in a one-off script):
+
+```python
+from my.ip.all import ips
+from my.core.denylist import DenyList
+
+d = DenyList("~/data/ip_denylist.json")
+
+for ip in ips():
+    # some custom code you define
+    if ip.addr == ...:
+        d.deny(key="ip", value=ip.ip)
+    d.write()
+```
+
+... or interactively, which requires [`fzf`](https://github.com/junegunn/fzf) and [`pyfzf-iter`](https://pypi.org/project/pyfzf-iter/) (`python3 -m pip install pyfzf-iter`) to be installed:
+
+```python
+from my.ip.all import ips
+from my.core.denylist import DenyList
+
+d = DenyList("~/data/ip_denylist.json")
+d.deny_cli(ips())  # automatically writes after each selection
+```
+
+That will open up an interactive `fzf` prompt, where you can select an item to add to the denylist
+
+This is meant for relatively simple filters, where you want to filter items out
+based on a single attribute of a namedtuple/dataclass. If you want to do something
+more complex, I would recommend overriding the `all.py` file for that source and
+writing your own filter function there.
+
+For more info on all.py:
+
+https://github.com/karlicoss/HPI/blob/master/doc/MODULE_DESIGN.org#allpy
+
+This would typically be used in an overridden `all.py` file, or in a one-off script
+which you may want to filter out some items from a source, progressively adding more
+items to the denylist as you go.
+
+A potential `my/ip/all.py` file might look like (Sidenote: `discord` module from [here](https://github.com/purarue/HPI)):
+
+```python
+from typing import Iterator
+
+from my.ip.common import IP
+from my.core.denylist import DenyList
+
+deny = DenyList("~/data/ip_denylist.json")
+
+# all possible data from the source
+def _ips() -> Iterator[IP]:
+    from my.ip import discord
+    # could add other imports here
+
+    yield from discord.ips()
+
+
+# filtered data
+def ips() -> Iterator[IP]:
+    yield from deny.filter(_ips())
+```
+
+To add items to the denylist, you could create a `__main__.py` in your namespace package (in this case, `my/ip/__main__.py`), with contents like:
+
+```python
+from my.ip import all
+
+if __name__ == "__main__":
+    all.deny.deny_cli(all.ips())
+```
+
+Which could then be called like: `python3 -m my.ip`
+
+Or, you could just run it from the command line:
+
+```
+python3 -c 'from my.ip import all; all.deny.deny_cli(all.ips())'
+```
+
+To edit the `all.py`, you could either:
+
+- install it as editable (`python3 -m pip install --user -e ./HPI`), and then edit the file directly
+- or, create a namespace package, which splits the package across multiple directories. For info on that see [`MODULE_DESIGN`](https://github.com/karlicoss/HPI/blob/master/doc/MODULE_DESIGN.org#namespace-packages), [`reorder_editable`](https://github.com/purarue/reorder_editable), and possibly the [`HPI-template`](https://github.com/purarue/HPI-template) to create your own HPI namespace package to create your own `all.py` file.
+
+For a real example of this see, [purarue/HPI-personal](https://github.com/purarue/HPI-personal/blob/master/my/ip/all.py)
+
+Sidenote: the reason why we want to specifically override
+the all.py and not just create a script that filters out the items you're
+not interested in is because we want to be able to import from `my.ip.all`
+or `my.location.all` from other modules and get the filtered results, without
+having to mix data filtering logic with parsing/loading/caching (the stuff HPI does)

+
+   Depending on the specific data provider and your level of paranoia you might expect different behaviour.. E.g.:
+    - if your objects already have tz info, you might not need to call localize() at all
+    - it's safer when either all of your objects are tz aware or all are tz unware, not a mixture
+    - you might trust your original timezone, or it might just be UTC, and you want to use something more reasonable

+Some thoughts on modules, how to structure them, and adding your own/extending HPI
+
+This is slightly more advanced, and would be useful if you're trying to extend HPI by developing your own modules, or contributing back to HPI

+
+* all.py
+
+Some modules have lots of different sources for data. For example, ~my.location~ (location data) has lots of possible sources -- from ~my.google.takeout.parser~, using the ~gpslogger~ android app, or through geo locating ~my.ip~ addresses. For a module with multiple possible sources, its common to split it into files like:
+
+    #+begin_src
+    my/location
+    ├── all.py -- specifies all possible sources/combines/merges data
+    ├── common.py  -- defines shared code, e.g. to merge data from across entries, a shared model (namedtuple/dataclass) or protocol
+    ├── google_takeout.py  -- source for data using my.google.takeout.parser
+    ├── gpslogger.py -- source for data using gpslogger
+    ├── home.py -- fallback source
+    └── via_ip.py -- source using my.ip
+    #+end_src
+
+Its common for each of those sources to have their own file, like ~my.location.google_takeout~, ~my.location.gpslogger~ and ~my.location.via_ip~, and then they all get merged into a single function in ~my.location.all~, like:
+
+    #+begin_src python
+    from .common import Location
+
+    def locations() -> Iterator[Location]:
+        # can add/comment out sources here to enable/disable them
+        yield from _takeout_locations()
+        yield from _gpslogger_locations()
+
+
+    @import_source(module_name="my.location.google_takeout")
+    def _takeout_locations() -> Iterator[Location]:
+        from . import google_takeout
+        yield from google_takeout.locations()
+
+
+    @import_source(module_name="my.location.gpslogger")
+    def _gpslogger_locations() -> Iterator[Location]:
+        from . import gpslogger
+        yield from gpslogger.locations()
+    #+end_src
+
+If you want to disable a source, you have a few options.
+
+  - If you're using a local editable install or just want to quickly troubleshoot, you can just comment out the line in the ~locations~ function
+  - Since these are decorated behind ~import_source~, they automatically catch import/config errors, so instead of fatally erroring and crashing if you don't have a module setup, it'll warn you and continue to process the other sources. To get rid of the warnings, you can add the module you're not planning on using to your core config, like:
+
+#+begin_src python
+    class core:
+        disabled_modules = (
+            "my.location.gpslogger",
+            "my.location.via_ip",
+        )
+#+end_src
+
+... that suppresses the warning message and lets you use ~my.location.all~ without having to change any lines of code
+
+Another benefit is that all the custom sources/data is localized to the ~all.py~ file, so a user can override the ~all.py~ (see the sections below on ~namespace packages~) file in their own HPI repository, adding additional sources without having to maintain a fork and patching in changes as things eventually change. For a 'real world' example of that, see [[https://github.com/purarue/HPI#partially-in-usewith-overrides][purarue]]s location and ip modules.
+
+This is of course not required for personal or single file modules, its just the pattern that seems to have the least amount of friction for the user, while being extendable, and without using a bulky plugin system to let users add additional sources.
+
+Another common way an ~all.py~ file is used is to merge data from a periodic export, and a GDPR export (e.g. see the ~stackexchange~, or ~github~ modules)
+
+* module count
+
+ Having way too many modules could end up being an issue. For now, I'm basically happy to merge new modules - With the current module count, things don't seem to break much, and most of them are modules I use myself, so they get tested with my own data.
+
+ For services I don't use, I would prefer if they had tests/example data somewhere, else I can't guarantee they're still working...
+
+ Its great if when you start using HPI, you get a few modules 'for free' (perhaps ~github~ and ~reddit~), but its likely not everyone uses the same services
+
+ This shouldn't end up becoming a monorepo (a la [[https://www.spacemacs.org/][Spacemacs]]) with hundreds of modules supporting every use case. Its hard to know what the common usecase is for everyone, and new services/companies which silo your data appear all the time...
+
+ Its also not obvious how people want to access their data. This problem is often mitigated by the output of HPI being python functions -- one can always write a small script to take the output data from a module and wrangle it into some format you want
+
+ This is why HPI aims to be as extendable as possible. If you have some programming know-how, hopefully you're able to create some basic modules for yourself - plug in your own data and gain the benefits of using the functions in ~my.core~, the configuration layer and possibly libraries like [[https://github.com/karlicoss/cachew][cachew]] to 'automatically' cache your data
+
+ In some ways it may make sense to think of HPI as akin to emacs or a ones 'dotfiles'. This provides a configuration layer and structure for you to access your data, and you can extend it to your own use case.
+
+* single file modules
+
+... or, the question 'should we split code from individual HPI files into setuptools packages'
+
+It's possible for a single HPI module or file to handle *everything*. Most of the python files in ~my/~ are 'single file' modules
+
+By everything, I mean:
+
+ - Exporting data from an API/locating data on your disk/maybe saving data so you don't lose it
+ - Parsing data from some raw (JSON/SQLite/HTML) format
+ - Merging different data sources into some common =NamedTuple=-like schema
+ - caching expensive computation/merge results
+ - configuration through ~my.config~
+
+For short modules which aren't that complex, while developing your own personal modules, or while bootstrapping modules - this is actually fine.
+
+From a users perspective, the ability to clone and install HPI as editable, add an new python file into ~my/~, and it immediately be accessible as ~my.modulename~ is a pattern that should always be supported
+
+However, as modules get more and more complex, especially if they include backing up/locating data from some location on your filesystem or interacting with a live API -- ideally they should be split off into their own repositories. There are trade-offs to doing this, but they are typically worth it.
+
+As an example of this, take a look at the [[https://github.com/karlicoss/HPI/tree/5ef277526577daaa115223e79a07a064ffa9bc85/my/github][my.github]] and the corresponding [[https://github.com/karlicoss/ghexport][ghexport]] data exporter which saves github data.
+
+- Pros:
+  - This allows someone to install and use ~ghexport~ without having to setup HPI at all -- its a standalone tool which means there's less barrier to entry
+  - It being a separate repository means issues relating to exporting data and the [[https://beepb00p.xyz/exports.html#dal][DAL]] (loading the data) can be handled there, instead of in HPI
+  - This reduces complexity for someone looking at the ~my.github~ files trying to debug issues related to HPI. The functionality for ~ghexport~ can be tested independently of someone new to HPI trying to debug a configuration issue
+  - Is easier to combine additional data sources, like ~my.github.gdpr~, which includes additional data from the GDPR export
+
+- Cons:
+  - Leads to some code duplication, as you can no longer use helper functions from ~my.core~ in the new repository
+  - Additional boilerplate - instructions, installation scripts, testing. It's not required, but typically you want to leverage ~setuptools~ to allows ~pip install git+https...~ type installs, which are used in ~hpi module install~
+  - Is difficult to convert to a namespace module/directory down the road
+
+Not all HPI Modules are currently at that level of complexity -- some are simple enough that one can understand the file by just reading it top to bottom. Some wouldn't make sense to split off into separate modules for one reason or another.
+
+A related concern is how to structure namespace packages to allow users to easily extend them, and how this conflicts with single file modules (Keep reading below for more information on namespace packages/extension) If a module is converted from a single file module to a namespace with multiple files, it seems this is a breaking change, see [[https://github.com/karlicoss/HPI/issues/89][#89]] for an example of this. The current workaround is to leave it a regular python package with an =__init__.py= for some amount of time and send a deprecation warning, and then eventually remove the =__init__.py= file to convert it into a namespace package. For an example, see the [[https://github.com/karlicoss/HPI/blob/8422c6e420f5e274bd1da91710663be6429c666c/my/reddit/__init__.py][reddit init file]].
+
+Its quite a pain to have to convert a file from a single file module to a namespace module, so if there's *any* possibility that you might convert it to a namespace package, might as well just start it off as one, to avoid the pain down the road. As an example, say you were creating something to parse ~zsh~ history. Instead of creating ~my/zsh.py~, it would be better to create ~my/zsh/parser.py~. That lets users override the file using editable/namespace packages, and it also means in the future its much more trivial to extend it to something like:
+
+  #+begin_src
+  my/zsh
+  ├── all.py -- e.g. combined/unique/sorted zsh history
+  ├── aliases.py -- parse zsh alias files
+  ├── common.py  -- shared models/merging code
+  ├── compdump.py -- parse zsh compdump files
+  └── parser.py -- parse individual zsh history files
+  #+end_src
+
+There's no requirement to follow this entire structure when you start off, the entire module could live in ~my/zsh/parser.py~, including all the merging/parsing/locating code. It just avoids the trouble in the future, and the only downside is having to type a bit more when importing from it.
+

+
+* Adding new modules
+
+  As always, if the changes you wish to make are small, or you just want to add a few modules, you can clone and edit an editable install of HPI. See [[file:SETUP.org][SETUP]] for more information
+
+  The "proper way" (unless you want to contribute to the upstream) is to create a separate file hierarchy and add your module to =PYTHONPATH= (or use 'editable namespace packages' as described below, which also modifies your computed ~sys.path~)
+
+# TODO link to 'overlays' documentation?
+  You can check my own [[https://github.com/karlicoss/hpi-personal-overlay][personal overlay]] as a reference.
+
+  For example, if you want to add an =awesomedatasource=, it could be:
+
+  : custom_module
+  : └── my
+  :     └──awesomedatasource.py
+
+  You can use all existing HPI modules in =awesomedatasource.py=, including =my.config= and everything from =my.core=.
+  =hpi modules= or =hpi doctor= commands should also detect your extra modules.
+
+- In addition, you can *override* the builtin HPI modules too:
+
+  : custom_lastfm_overlay
+  : └── my
+  :     └──lastfm.py
+
+  Now if you add =custom_lastfm_overlay= [[https://docs.python.org/3/using/cmdline.html#envvar-PYTHONPATH][*in front* of ~PYTHONPATH~]], all the downstream scripts using =my.lastfm= will load it from =custom_lastfm_overlay= instead.
+
+  This could be useful to monkey patch some behaviours, or dynamically add some extra data sources -- anything that comes to your mind.
+  You can check [[https://github.com/karlicoss/hpi-personal-overlay/blob/7fca8b1b6031bf418078da2d8be70fd81d2d8fa0/src/my/calendar/holidays.py#L1-L14][my.calendar.holidays]] in my personal overlay as a reference.
+
+** Namespace Packages
+
+Note: this section covers some of the complexities and benefits with this being a namespace package and/or editable install, so it assumes some familiarity with python/imports
+
+HPI is installed as a namespace package, which allows an additional way to add your own modules. For the details on namespace packages, see [[https://www.python.org/dev/peps/pep-0420/][PEP420]], or the  [[https://packaging.python.org/guides/packaging-namespace-packages][packaging docs for a summary]], but for our use case, a sufficient description might be: Namespace packages let you split a package across multiple directories on disk.
+
+Without adding a bulky/boilerplate-y plugin framework to HPI, as that increases the barrier to entry, [[https://packaging.python.org/guides/creating-and-discovering-plugins/#using-namespace-packages][namespace packages offers an alternative]] with little downsides.
+
+Creating a separate file hierarchy still allows you to keep up to date with any changes from this repository by running ~git pull~ on your local clone of HPI periodically (assuming you've installed it as an editable package (~pip install -e .~)), while creating your own modules, and possibly overwriting any files you wish to override/overlay.
+
+In order to do that, like stated above, you could edit the ~PYTHONPATH~ variable, which in turn modifies your computed ~sys.path~, which is how python [[https://docs.python.org/3/library/sys.html?highlight=pythonpath#sys.path][determines the search path for modules]]. This is sort of what [[file:../with_my][with_my]] allows you to do.
+
+In the context of HPI, it being a namespace package means you can have a local clone of this repository, and your own 'HPI' modules in a separate folder, which then get combined into the ~my~ package.
+
+As an example, say you were trying to override the ~my.lastfm~ file, to include some new feature. You could create a new file hierarchy like:
+
+: .
+: ├── my
+: │   ├── lastfm.py
+: │   └── some_new_module.py
+: └── setup.py
+
+Where ~lastfm.py~ is your version of ~my.lastfm~, which you've copied from this repository and applied your changes to. The ~setup.py~ would be something like:
+
+    #+begin_src python
+    from setuptools import setup, find_namespace_packages
+
+    # should use a different name,
+    # so its possible to differentiate between HPI installs
+    setup(
+        name=f"my-HPI-overlay",
+        zip_safe=False,
+        packages=find_namespace_packages(".", include=("my*")),
+    )
+    #+end_src
+
+Then, running ~python3 -m pip install -e .~ in that directory would install that as part of the namespace package, and assuming (see below for possible issues) this appears on ~sys.path~ before the upstream repository, your ~lastfm.py~ file overrides the upstream. Adding more files, like ~my.some_new_module~ into that directory immediately updates the global ~my~ package -- allowing you to quickly add new modules without having to re-install.
+
+If you install both directories as editable packages (which has the benefit of any changes you making in either repository immediately updating the globally installed ~my~ package), there are some concerns with which editable install appears on your ~sys.path~ first. If you wanted your modules to override the upstream modules, yours would have to appear on the ~sys.path~ first (this is the same reason that =custom_lastfm_overlay= must be at the front of your ~PYTHONPATH~). For more details and examples on dealing with editable namespace packages in the context of HPI, see the [[https://github.com/purarue/reorder_editable][reorder_editable]] repository.
+
+There is no limit to how many directories you could install into a single namespace package, which could be a possible way for people to install additional HPI modules, without worrying about the module count here becoming too large to manage.
+
+There are some other users [[https://github.com/hpi/hpi][who have begun publishing their own modules]] as namespace packages, which you could potentially install and use, in addition to this repository, if any of those interest you. If you want to create your own you can use the [[https://github.com/purarue/HPI-template][template]] to get started.
+
+Though, enabling this many modules may make ~hpi doctor~ look pretty busy. You can explicitly choose to enable/disable modules with a list of modules/regexes in your [[https://github.com/karlicoss/HPI/blob/f559e7cb899107538e6c6bbcf7576780604697ef/my/core/core_config.py#L24-L55][core config]], see [[https://github.com/purarue/dotfiles/blob/a1a77c581de31bd55a6af3d11b8af588614a207e/.config/my/my/config/__init__.py#L42-L72][here]] for an example.
+
+You may use the other modules or [[https://github.com/karlicoss/hpi-personal-overlay][my overlay]] as reference, but python packaging is already a complicated issue, before adding complexities like namespace packages and editable installs on top of it... If you're having trouble extending HPI in this fashion, you can open an issue here, preferably with a link to your code/repository and/or ~setup.py~ you're trying to use.
+
+* An Extendable module structure
+
+In this context, 'overlay'/'override' means you create your own namespace package/file structure like described above, and since your files are in front of the upstream repository files in the computed ~sys.path~ (either by using namespace modules, the ~PYTHONPATH~ or ~with_my~), your file overrides the upstream repository
+
+Related issues: [[https://github.com/karlicoss/HPI/issues/102][#102]], [[https://github.com/karlicoss/HPI/issues/89][#89]], [[https://github.com/karlicoss/HPI/issues/154][#154]]
+
+The main goals are:
+
+- low effort: ideally it should be a matter of a few lines of code to override something.
+- good interop: e.g. ability to keep with the upstream, use modules coming from separate repositories, etc.
+- ideally mypy friendly. This kind of means 'not too dynamic and magical', which is ultimately a good thing even if you don't care about mypy.
+
+~all.py~ using modules/sources behind ~import_source~ is the solution we've arrived at in HPI, because it meets all of these goals:
+
+ - it doesn't require an additional plugin system, is just python imports and
+   namespace packages
+ - is generally mypy friendly (the only exception is the ~import_source~
+   decorator, but that typically returns nothing if the import failed)
+ - doesn't require you to maintain a fork of this repository, though you can maintain a separate HPI repository (so no patching/merge conflicts)
+ - allows you to easily add/remove sources to the ~all.py~ module, either by:
+    - overriding an ~all.py~ in your own repository
+    - just commenting out the source/adding 2 lines to import and ~yield from~ your new source
+    - doing nothing! (~import_source~ will catch the error and just warn you
+      and continue to work without changing any code)
+
+It could be argued that namespace packages and editable installs are a bit complex for a new user to get the hang of, and this is true. But fortunately ~import_source~ means any user just using HPI only needs to follow the instructions when a warning is printed, or peruse the docs here a bit -- there's no need to clone or create your own override to just use the ~all.py~ file.
+
+There's no requirement to use this for individual modules, it just seems to be the best solution we've arrived at so far
+
+* Logging guidelines
+HPI doesn't enforce any specific logging mechanism, you're free to use whatever you prefer in your modules.
+
+However there are some general guidelines for developing modules that can make them more pleasant to use.
+
+- each module should have its unique logger, the easiest way to ensure that is simply use module's ~__name__~ attribute as the logger name
+
+  In addition, this ensures the logger hierarchy reflect the package hierarchy.
+  For instance, if you initialize the logger for =my.module= with specific settings, the logger for =my.module.helper= would inherit these settings. See more on that [[ https://docs.python.org/3/library/logging.html?highlight=logging#logger-objects][in python docs]].
+
+  As a bonus, if you use the module ~__name__~, this logger will be automatically be picked up and used by ~cachew~.
+
+- often modules are processing multiple files, extracting data from each one ([[https://beepb00p.xyz/exports.html#types][incremental/synthetic exports]])
+
+  It's nice to log each file name you're processing as =logger.info= so the user of module gets a sense of progress.
+  If possible, add the index of file you're processing and the total count.
+
+  #+begin_src python
+  def process_all_data():
+      paths = inputs()
+      total = len(paths)
+      width = len(str(total))
+      for idx, path in enumerate(paths):
+          # :>{width} to align the logs vertically
+          logger.info(f'processing [{idx:>{width}}/{total:>{width}}] {path}')
+          yield from process_path(path)
+  #+end_src
+
+  If there is a lot of logging happening related to a specific path, instead of adding path to each logging message manually, consider using [[https://docs.python.org/3/library/logging.html?highlight=loggeradapter#logging.LoggerAdapter][LoggerAdapter]].
+
+- log exceptions, but sparingly
+
+  Generally it's a good practice to call ~logging.exception~ from the ~except~ clause, so it's immediately visible where the errors are happening.
+
+  However, in HPI, instead of crashing on exceptions we often behave defensively and ~yield~ them instead (see [[https://beepb00p.xyz/mypy-error-handling.html][mypy assisted error handling]]).
+
+  In this case logging every time may become a bit spammy, so use exception logging sparingly in this case.
+  Typically it's best to rely on the downstream data consumer to handle the exceptions properly.
+
+- instead of =logging.getLogger=, it's best to use =my.core.make_logger=
+
+  #+begin_src python
+      from my.core import make_logger
+
+      logger = make_logger(__name__)
+
+      # or to set a custom level
+      logger = make_logger(__name__, level='warning')
+  #+end_src
+
+  This sets up some nicer defaults over standard =logging= module:
+
+  - colored logs (via =colorlog= library)
+  - =INFO= as the initial logging level (instead of default =ERROR=)
+  - logging full exception trace when even when logging outside of the exception handler
+
+    This is particularly useful for [[https://beepb00p.xyz/mypy-error-handling.html][mypy assisted error handling]].
+
+    By default, =logging= only logs the exception message (without the trace) in this case, which makes errors harder to debug.
+  - control logging level from the shell via ~LOGGING_LEVEL_*~ env variable
+
+    This can be useful to suppress logging output if it's too spammy, or showing more output for debugging.
+
+    E.g. ~LOGGING_LEVEL_my_instagram_gdpr=DEBUG hpi query my.instagram.gdpr.messages~
+
+  - experimental: passing env variable ~LOGGING_COLLAPSE=<loglevel>~ will "collapse" logging with the same level
+
+    Instead of printing new logging line each time, it will 'redraw' the last logged line with a new logging message.
+
+    This can be convenient if there are too many logs, you just need logging to get a sense of progress.
+
+  - experimental: passing env variable ~ENLIGHTEN_ENABLE=yes~ will display TUI progress bars in some cases
+
+    See [[https://github.com/Rockhopper-Technologies/enlighten#readme][https://github.com/Rockhopper-Technologies/enlighten#readme]]
+
+    This can be convenient for showing the progress of parallel processing of different files from HPI:

+NOTE this kinda overlaps with [[file:MODULE_DESIGN.org][the module design doc]], should be unified in the future.
+
+Relevant discussion about overlays: https://github.com/karlicoss/HPI/issues/102
+
+# This is describing TODO
+# TODO goals
+# - overrides
+# - proper mypy support
+# - TODO reusing parent modules?
+
+# You can see them TODO in overlays dir
+
+Consider a toy package/module structure with minimal code, without any actual data parsing, just for demonstration purposes.
+
+- =main= package structure
+  # TODO do links
+
+  - =my/twitter/gdpr.py=
+    Extracts Twitter data from GDPR archive.
+  - =my/twitter/all.py=
+    Merges twitter data from multiple sources (only =gdpr= in this case), so data consumers are agnostic of specific data sources used.
+    This will be overridden by =overlay=.
+  - =my/twitter/common.py=
+    Contains helper function to merge data, so they can be reused by overlay's =all.py=.
+  - =my/reddit.py=
+    Extracts Reddit data -- this won't be overridden by the overlay, we just keep it for demonstration purposes.
+
+- =overlay= package structure
+
+  - =my/twitter/talon.py=
+    Extracts Twitter data from Talon android app.
+  - =my/twitter/all.py=
+    Override for =all.py= from =main= package -- it merges together data from =gpdr= and =talon= modules.
+
+# TODO mention resolution? reorder_editable
+
+* Installing (editable install)
+
+NOTE: this was tested with =python 3.10= and =pip 23.3.2=.
+
+To install, we run:
+
+: pip3 install --user -e overlay/
+: pip3 install --user -e main/
+
+# TODO mention non-editable installs (this bit will still work with non-editable install)
+
+As a result, we get:
+
+: pip3 list | grep hpi
+: hpi-main           0.0.0       /project/main/src
+: hpi-overlay        0.0.0       /project/overlay/src
+
+: cat ~/.local/lib/python3.10/site-packages/easy-install.pth
+: /project/overlay/src
+: /project/main/src
+
+(the order above is important, so =overlay= takes precedence over =main= TODO link)
+
+Verify the setup:
+
+: $ python3 -c 'import my; print(my.__path__)'
+: _NamespacePath(['/project/overlay/src/my', '/project/main/src/my'])
+
+This basically means that modules will be searched in both paths, with overlay taking precedence.
+
+** Installing with =--use-pep517=
+
+See here for discussion https://github.com/purarue/reorder_editable/issues/2, but TLDR it should work similarly.
+
+* Testing runtime behaviour (editable install)
+
+: $ python3 -c 'import my.reddit as R; print(R.upvotes())'
+: [main] my.reddit hello
+: ['reddit upvote1', 'reddit upvote2']
+
+Just as expected here, =my.reddit= is imported from the =main= package, since it doesn't exist in =overlay=.
+
+Let's theck twitter now:
+
+: $ python3 -c 'import my.twitter.all as T; print(T.tweets())'
+: [overlay] my.twitter.all hello
+: [main] my.twitter.common hello
+: [main] my.twitter.gdpr hello
+: [overlay] my.twitter.talon hello
+: ['gdpr tweet 1', 'gdpr tweet 2', 'talon tweet 1', 'talon tweet 2']
+
+As expected, =my.twitter.all= was imported from the =overlay=.
+As you can see it's merged data from =gdpr= (from =main= package) and =talon= (from =overlay= package).
+
+So far so good, let's see how it works with mypy.
+
+* Mypy support (editable install)
+
+To check that mypy works as expected I injected some statements in modules that have no impact on runtime,
+but should trigger mypy, like this =trigger_mypy_error: str = 123=:
+
+Let's run it:
+
+: $ mypy --namespace-packages --strict -p my
+: overlay/src/my/twitter/talon.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "str")
+: [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^
+: Found 1 error in 1 file (checked 4 source files)
+
+Hmm, this did find the statement in the =overlay=, but missed everything from =main= (e.g. =reddit.py= and =gdpr.py= should have also triggered the check).
+
+First, let's check which sources mypy is processing:
+
+: $ mypy --namespace-packages --strict -p my -v 2>&1 | grep BuildSource
+: LOG:  Found source:           BuildSource(path='/project/overlay/src/my', module='my', has_text=False, base_dir=None)
+: LOG:  Found source:           BuildSource(path='/project/overlay/src/my/twitter', module='my.twitter', has_text=False, base_dir=None)
+: LOG:  Found source:           BuildSource(path='/project/overlay/src/my/twitter/all.py', module='my.twitter.all', has_text=False, base_dir=None)
+: LOG:  Found source:           BuildSource(path='/project/overlay/src/my/twitter/talon.py', module='my.twitter.talon', has_text=False, base_dir=None)
+
+So seems like mypy is not processing anything from =main= package at all?
+
+At this point I cloned mypy, put a breakpoint, and found out this is the culprit: https://github.com/python/mypy/blob/1dd8e7fe654991b01bd80ef7f1f675d9e3910c3a/mypy/modulefinder.py#L288
+
+This basically returns the first path where it finds =my= package, which happens to be the overlay in this case.
+So everything else is ignored?
+
+It even seems to have a test for a similar usecase, which is quite sad.
+https://github.com/python/mypy/blob/1dd8e7fe654991b01bd80ef7f1f675d9e3910c3a/mypy/test/testmodulefinder.py#L64-L71
+
+For now, I opened an issue in mypy repository https://github.com/python/mypy/issues/16683
+
+But ok, maybe mypy treats =main= as an external package somehow but still type checks it properly?
+Let's see what's going on with imports:
+
+: $ mypy --namespace-packages --strict -p my --follow-imports=error
+: overlay/src/my/twitter/talon.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "str")
+: [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^
+: overlay/src/my/twitter/all.py:3: error: Import of "my.twitter.common" ignored  [misc]
+:     from .common import merge
+:     ^
+: overlay/src/my/twitter/all.py:6: error: Import of "my.twitter.gdpr" ignored  [misc]
+:         from . import gdpr
+:     ^
+: overlay/src/my/twitter/all.py:6: note: (Using --follow-imports=error, module not passed on command line)
+: overlay/src/my/twitter/all.py: note: In function "tweets":
+: overlay/src/my/twitter/all.py:8: error: Returning Any from function declared to return "List[str]"  [no-any-return]
+:         return merge(gdpr, talon)
+:         ^
+: Found 4 errors in 2 files (checked 4 source files)
+
+Nope -- looks like it's completely unawareof =main=, and what's worst, by default (without tweaking =--follow-imports=), these errors would be suppressed.
+
+What if we check =my.twitter= directly?
+
+: $ mypy --namespace-packages --strict -p my.twitter  --follow-imports=error
+: overlay/src/my/twitter/talon.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "str")
+: [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^~~
+: overlay/src/my/twitter: error: Ancestor package "my" ignored  [misc]
+: overlay/src/my/twitter: note: (Using --follow-imports=error, submodule passed on command line)
+: overlay/src/my/twitter/all.py:3: error: Import of "my.twitter.common" ignored  [misc]
+:     from .common import merge
+:     ^
+: overlay/src/my/twitter/all.py:3: note: (Using --follow-imports=error, module not passed on command line)
+: overlay/src/my/twitter/all.py:6: error: Import of "my.twitter.gdpr" ignored  [misc]
+:         from . import gdpr
+:     ^
+: overlay/src/my/twitter/all.py: note: In function "tweets":
+: overlay/src/my/twitter/all.py:8: error: Returning Any from function declared to return "list[str]"  [no-any-return]
+:         return merge(gdpr, talon)
+:         ^~~~~~~~~~~~~~~~~~~~~~~~~
+: Found 5 errors in 3 files (checked 3 source files)
+
+Now we're also getting =error: Ancestor package "my" ignored  [misc]= .. not ideal.
+
+* What if we don't install at all?
+Instead of editable install let's try running mypy directly over source files
+
+First let's only check =main= package:
+
+: $ MYPYPATH=main/src mypy --namespace-packages --strict -p my
+: main/src/my/twitter/gdpr.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "str")  [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^~~
+: main/src/my/reddit.py:11: error: Incompatible types in assignment (expression has type "int", variable has type "str")  [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^~~
+: Found 2 errors in 2 files (checked 6 source files)
+
+As expected, it found both errors.
+
+Now with overlay as well:
+
+: $ MYPYPATH=overlay/src:main/src mypy --namespace-packages --strict -p my
+: overlay/src/my/twitter/all.py:6: note: In module imported here:
+: main/src/my/twitter/gdpr.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "str")  [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^~~
+: overlay/src/my/twitter/talon.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "str")
+: [assignment]
+:     trigger_mypy_error: str = 123
+:                               ^~~
+: Found 2 errors in 2 files (checked 4 source files)
+
+Interesting enough, this is slightly better than the editable install (it detected error in =gdpr.py= as well).
+But still no =reddit.py= error.
+
+TODO possibly worth submitting to mypy issue tracker as well...
+
+Overall it seems that properly type checking HPI setup as a whole is kinda problematic, especially if the modules actually override/extend base modules.
+
+* Modifying (monkey patching) original module in the overlay
+Let's say we want to modify/monkey patch =my.twitter.talon= module from =main=, for example, convert "gdpr" to uppercase, i.e. =tweet.replace('gdpr', 'GDPR')=.
+
+# TODO see overlay2/
+
+I think our options are:
+
+- symlink to the 'parent' packages, e.g. =main= in the case
+
+  Alternatively, somehow install =main= under a different name/alias (managed by pip).
+
+  This is discussed here: https://github.com/karlicoss/HPI/issues/102
+
+  The main upside is that it's relatively simple and (sort of works with mypy).
+
+  There are a few big downsides:
+  - creates a parallel package hierarchy (to the one maintained by pip), symlinks will need to be carefully managed manually
+
+    This may not be such a huge deal if you don't have too many overlays.
+    However this results in problems if you're trying to switch between two different HPI checkouts (e.g. stable and development). If you have symlinks into "stable" from the overlay then stable modules will sometimes be picked up when you're expecting "development" package.
+
+  - symlinks pointing outside of the source tree might cause pip install to go into infinite loop
+
+  - it modifies the package name
+
+    This may potentially result in some confusing behaviours.
+
+    One thing I noticed for example is that cachew caches might get duplicated.
+
+  - it might not work in all cases or might result in recursive imports
+
+- do not shadow the original module
+
+  Basically instead of shadowing via namespace package mechanism and creating identically named module,
+  create some sort of hook that would patch the original =my.twitter.talon= module from =main=.
+
+  The downside is that it's a bit unclear where to do that, we need some sort of entry point?
+
+  - it could be some global dynamic hook defined in the overlay, and then executed from =my.core=
+
+    However, it's a bit intrusive, and unclear how to handle errors. E.g. what if we're monkey patching a module that we weren't intending to use, don't have dependencies installed and it's crashing?
+
+    Perhaps core could support something like =_hook= in each of HPI's modules?
+    Note that it can't be =my.twitter.all=, since we might want to override =.all= itself.
+
+    The downside is is this probably not going to work well with =tmp_config= and such -- we'll need to somehow execute the hook again on reloading the module?
+
+  - ideally we'd have something that integrates with =importlib= and executed automatically when module is imported?
+
+    TODO explore these:
+
+    - https://stackoverflow.com/questions/43571737/how-to-implement-an-import-hook-that-can-modify-the-source-code-on-the-fly-using
+    - https://github.com/brettlangdon/importhook
+
+      This one is pretty intrusive, and has some issues, e.g. https://github.com/brettlangdon/importhook/issues/4
+
+      Let's try it:
+      : $ PYTHONPATH=overlay3/src:main/src python3 -c 'import my.twitter._hook; import my.twitter.all as M; print(M.tweets())'

+
+    In addition, still the question is where to put the hook itself, but in that case even a global one could be fine.
+
+  - define hook in =my/twitter/__init__.py=

+
+    This actually seems to work??

+    : [main] my.twitter.all hello
+    : [main] my.twitter.common hello
+    : ['GDPR tweet 1', 'GDPR tweet 2']
+
+    However, this doesn't stack, i.e. if the 'parent' overlay had its own =__init__.py=, it won't get called.
+
+- shadow the original module and temporarily modify =__path__= before importing the same module from the parent overlay
+
+  This approach is implemented in =my.core.experimental.import_original_module=
+
+  TODO demonstrate it properly, but I think that also works in a 'chain' of overlays
+
+  Seems like that option is the most promising so far, albeit very hacky.
+
+Note that none of these options work well with mypy (since it's all dynamic hackery), even if you disregard the issues described in the previous sections.

+`hpi query` is a command line tool for querying the output of any `hpi` function.
+
+```
+Usage: hpi query [OPTIONS] FUNCTION_NAME...
+
+  This allows you to query the results from one or more functions in HPI
+
+  By default this runs with '-o json', converting the results to JSON and
+  printing them to STDOUT
+
+  You can specify '-o pprint' to just print the objects using their repr, or
+  '-o repl' to drop into a ipython shell with access to the results
+
+  While filtering using --order-key datetime, the --after, --before and
+  --within flags parse the input to their datetime and timedelta equivalents.
+  datetimes can be epoch time, the string 'now', or an date formatted in the
+  ISO format. timedelta (durations) are parsed from a similar format to the
+  GNU 'sleep' command, e.g. 1w2d8h5m20s -> 1 week, 2 days, 8 hours, 5 minutes,
+  20 seconds
+
+  As an example, to query reddit comments I've made in the last month
+
+  hpi query --order-type datetime --before now --within 4w my.reddit.all.comments
+  or...
+  hpi query --recent 4w my.reddit.all.comments
+
+  Can also query within a range. To filter comments between 2016 and 2018:
+  hpi query --order-type datetime --after '2016-01-01' --before '2019-01-01' my.reddit.all.comments

+                                  while ordering, drop those items from the
+                                  results
+  --wrap-unsorted                 if the order of an item can't be determined

+                                  errors on STDERR
+  --raise-exceptions              if any errors are returned (as objects, not

+  --help                          Show this message and exit.
+```
+
+This works with any function which returns an iterable, for example `my.coding.commits`, which searches for `git commit`s on your computer:
+
+```bash
+hpi query my.coding.commits
+```
+
+When run with a module, this does some analysis of the functions in that module and tries to find ones that look like data sources. If it can't figure out which, it prompts you like:
+
+```
+Which function should be used from 'my.coding.commits'?
+
+	1. commits
+	2. repos
+```
+
+You select the one you want by clicking `1` or `2` on your keyboard. Otherwise, you can provide a fully qualified path, like:
+
+```
+hpi query my.coding.commits.repos
+```
+
+The corresponding `repos` function this queries is defined in [`my/coding/commits.py`](../my/coding/commits.py)
+
+### Ordering/Filtering/Streaming
+
+By default, this just returns the items in the order they were returned by the function. This allows you to filter by specifying a `--order-key`, or `--order-type`. For example, to get the 10 most recent commits. `--order-type datetime` will try to automatically figure out which attribute to use. If it chooses the wrong one (since `Commit`s have both a `committed_dt` and `authored_dt`), you could tell it which to use. For example, to scan my computer and find the most recent commit I made:
+
+```
+hpi query my.coding.commits.commits --order-key committed_dt --limit 1 --reverse --output pprint --stream
+Commit(committed_dt=datetime.datetime(2023, 4, 14, 23, 9, 1, tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=61200))),
+       authored_dt=datetime.datetime(2023, 4, 14, 23, 4, 1, tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=61200))),
+       message='sources.smscalls: propagate errors if there are breaking '
+               'schema changes',
+       repo='/home/username/Repos/promnesia-fork',
+       sha='22a434fca9a28df9b0915ccf16368df129d2c9ce',
+       ref='refs/heads/smscalls-handle-result')
+```
+
+To instead limit in some range, you can use `--before` and `--within` to filter by a range. For example, to get all the commits I committed in the last day:
+
+```
+hpi query my.coding.commits.commits --order-type datetime --before now --within 1d
+```
+
+That prints a a list of `Commit` as JSON objects. You could also use `--output pprint` to pretty-print the objects or `--output repl` drop into a REPL.
+
+To process the JSON, you can pipe it to [`jq`](https://github.com/stedolan/jq). I often use `jq length` to get the count of some output:
+
+```
+hpi query my.coding.commits.commits --order-type datetime --before now --within 1d | jq length
+6
+```
+
+Because grabbing data `--before now` is such a common use case, the `--recent` flag is a shorthand for `--order-type datetime --reverse --before now --within`. The same as above, to get the commits from the last day:
+
+```
+hpi query my.coding.commits.commits --recent 1d | jq length
+6
+```
+
+To select a range of commits, you can use `--after` and `--before`, passing ISO or epoch timestamps. Those can be full `datetimes` (`2021-01-01T00:05:30`) or just dates (`2021-01-01`). For example, to get all the commits I made on January 1st, 2021:
+
+```
+hpi query my.coding.commits.commits --order-type datetime --after 2021-01-01 --before 2021-01-02 | jq length
+1
+```
+
+If you have [`dateparser`](https://github.com/scrapinghub/dateparser#how-to-use) installed, this supports dozens more natural language formats:
+
+```
+hpi query my.coding.commits.commits --order-type datetime --after 'last week' --before 'day before yesterday' | jq length
+28
+```
+
+If you're having issues ordering because there are exceptions in your results not all data is sortable (may have `None` for some attributes), you can use `--drop-unsorted` to drop those items from the results, or `--drop-exceptions` to remove the exceptions
+
+You can also stream the results, which is useful for functions that take a while to process or have a lot of data. For example, if you wanted to pick a sha hash from a particular repo, you could combine `jq` to `select` and pick that attribute from the JSON:
+
+```
+hpi query my.coding.commits.commits --recent 30d --stream | jq 'select(.repo | contains("HPI"))' | jq '.sha' -r

+```
+
+`jq`s `select` function acts on a stream of JSON objects, not a list, so it filters the output of `hpi query` the objects are generated (the goal here is to conserve memory as items which aren't needed are filtered). The alternative would be to print the entire JSON list at the end, like:
+
+`hpi query my.coding.commits.commits --recent 30d | jq '.[] | select(.repo | contains("Repos/HPI"))' | jq '.sha' -r`, using `jq '.[]'` to convert the JSON list into a stream of JSON objects.
+
+## Usage on non-HPI code
+
+The command can accept any qualified function name, so this could for example be used to check the output of [`promnesia`](https://github.com/karlicoss/promnesia) sources:
+
+```
+hpi query promnesia.sources.smscalls | jq length
+371
+```
+
+This can be used on any function that produces an `Iterator`/`Generator` like output, as long as it can be called with no arguments.
+
+## GPX
+
+The `hpi query` command can also be used with the `--output gpx` flag to generate gpx files from a list of locations, like the ones defined in the `my.location` package. This could be used to extract some date range and create a `gpx` file which can then be visualized by a GUI application.
+
+This prints the contents for the `gpx` file to STDOUT, and prints warnings for any objects it could not convert to locations to STDERR, so pipe STDOUT to a output file, like `>out.gpx`
+
+```
+hpi query my.location.all --after '2021-07-01T00:00:00' --before '2021-07-05T00:00:00' --order-type datetime --output gpx >out.gpx
+```
+
+If you want to ignore any errors, you can use `--drop-exceptions`.
+
+To preview, you can use something like [`qgis`](https://qgis.org/en/site/) or for something easier more lightweight, [`gpxsee`](https://github.com/tumic0/GPXSee):
+
+`gpxsee out.gpx`:

+
+## Python reference
+
+The `hpi query` command is a CLI wrapper around the code in [`query.py`](../my/core/query.py) and [`query_range.py`](../my/core/query_range.py). The `select` function is the core of this, and `select_range` lets you specify dates, timedelta, start-end ranges, and other CLI-specific code.
+
+`my.core.query.select`:
+
+```
+    A function to query, order, sort and filter items from one or more sources
+    This supports iterables and lists of mixed types (including handling errors),
+    by allowing you to provide custom predicates (functions) which can sort
+    by a function, an attribute, dict key, or by the attributes values.
+
+    Since this supports mixed types, there's always a possibility
+    of KeyErrors or AttributeErrors while trying to find some value to order by,
+    so this provides multiple mechanisms to deal with that
+
+    'where' lets you filter items before ordering, to remove possible errors
+    or filter the iterator by some condition
+
+    There are multiple ways to instruct select on how to order items. The most
+    flexible is to provide an 'order_by' function, which takes an item in the
+    iterator, does any custom checks you may want and then returns the value to sort by
+
+    'order_key' is best used on items which have a similar structure, or have
+    the same attribute name for every item in the iterator. If you have a
+    iterator of objects whose datetime is accessed by the 'timestamp' attribute,
+    supplying order_key='timestamp' would sort by that (dictionary or attribute) key
+
+    'order_value' is the most confusing, but often the most useful. Instead of
+    testing against the keys of an item, this allows you to write a predicate
+    (function) to test against its values (dictionary, NamedTuple, dataclass, object).
+    If you had an iterator of mixed types and wanted to sort by the datetime,
+    but the attribute to access the datetime is different on each type, you can
+    provide `order_value=lambda v: isinstance(v, datetime)`, and this will
+    try to find that value for each type in the iterator, to sort it by
+    the value which is received when the predicate is true
+
+    'order_value' is often used in the 'hpi query' interface, because of its brevity.
+    Just given the input function, this can typically sort it by timestamp with
+    no human intervention. It can sort of be thought as an educated guess,
+    but it can always be improved by providing a more complete guess function
+
+    Note that 'order_value' is also the most computationally expensive, as it has
+    to copy the iterator in memory (using itertools.tee) to determine how to order it
+    in memory
+
+    The 'drop_exceptions', 'raise_exceptions', 'warn_exceptions' let you ignore or raise
+    when the src contains exceptions. The 'warn_func' lets you provide a custom function
+    to call when an exception is encountered instead of using the 'warnings' module
+
+    src:            an iterable of mixed types, or a function to be called,
+                    as the input to this function
+
+    where:          a predicate which filters the results before sorting
+
+    order_by:       a function which when given an item in the src,
+                    returns the value to sort by. Similar to the 'key' value
+                    typically passed directly to 'sorted'
+
+    order_key:      a string which represents a dict key or attribute name
+                    to use as they key to sort by
+
+    order_value:    predicate which determines which attribute on an ADT-like item to sort by,
+                    when given its value. lambda o: isinstance(o, datetime) is commonly passed to sort
+                    by datetime, without knowing the attributes or interface for the items in the src
+
+    default:        while ordering, if the order for an object cannot be determined,
+                    use this as the default value
+
+    reverse:        reverse the order of the resulting iterable
+
+    limit:          limit the results to this many items
+
+    drop_unsorted:  before ordering, drop any items from the iterable for which a
+                    order could not be determined. False by default
+
+    wrap_unsorted:  before ordering, wrap any items into an 'Unsortable' object. Place
+                    them at the front of the list. True by default
+
+    drop_exceptions: ignore any exceptions from the src
+
+    raise_exceptions: raise exceptions when received from the input src
+```
+
+`my.core.query_range.select_range`:
+
+```
+    A specialized select function which offers generating functions
+    to filter/query ranges from an iterable
+
+    order_key and order_value are used in the same way they are in select
+
+    If you specify order_by_value_type, it tries to search for an attribute
+    on each object/type which has that type, ordering the iterable by that value
+
+    unparsed_range is a tuple of length 3, specifying 'after', 'before', 'duration',
+    i.e. some start point to allow the computed value we're ordering by, some
+    end point and a duration (can use the RangeTuple NamedTuple to construct one)
+
+    (this is typically parsed/created in my.core.__main__, from CLI flags
+
+    If you specify a range, drop_unsorted is forced to be True
+```
+
+Those can be imported and accept any sort of iterator, `hpi query` just defaults to the output of functions here. As an example, see [`listens`](https://github.com/purarue/HPI-personal/blob/master/scripts/listens) which just passes an generator (iterator) as the first argument to `query_range`

 The config is simply a *python package* (named =my.config=), expected to be in =~/.config/my=.
+If you'd like to change the location of the =my.config= directory, you can set the =MY_CONFIG= environment variable. e.g. in your .bashrc add: ~export MY_CONFIG=$HOME/.my/~

+
+If you're having issues with ~cachew~ or want to show logs to troubleshoot what may be happening, you can pass the debug flag (e.g., ~hpi --debug doctor my.module_name~) or set the ~LOGGING_LEVEL_HPI~ environment variable (e.g., ~LOGGING_LEVEL_HPI=debug hpi query my.module_name~) to print all logs, including the ~cachew~ dependencies. ~LOGGING_LEVEL_HPI~ could also be used to silence ~info~ logs, like ~LOGGING_LEVEL_HPI=warning hpi ...~

+To enable completion for the `hpi` command:
+
+If you don't want to use the files here, you can do this when you launch your shell like:
+
+```bash
+eval "$(_HPI_COMPLETE=bash_source hpi)"  # in ~/.bashrc
+eval "$(_HPI_COMPLETE=zsh_source hpi)"  # in ~/.zshrc
+eval "$(_HPI_COMPLETE=fish_source hpi)"  # in ~/.config/fish/config.fish
+```
+
+That is slightly slower since its generating the completion code on the fly -- see [click docs](https://click.palletsprojects.com/en/8.0.x/shell-completion/#enabling-completion) for more info
+
+To use the generated completion files in this repository, you need to source the file in `./bash`, `./zsh`, or `./fish` depending on your shell.
+
+If you don't have HPI cloned locally, after installing `HPI` you can generate the file yourself using one of the commands above. For example, for `bash`: `_HPI_COMPLETE=bash_source hpi > ~/.config/hpi_bash_completion`, and then source it like `source ~/.config/hpi_bash_completion`
+
+### bash
+
+Put `source /path/to/hpi/repo/misc/completion/bash/_hpi` in your `~/.bashrc`
+
+### zsh
+
+You can either source the file:
+
+`source /path/to/hpi/repo/misc/completion/zsh/_hpi`
+
+..or add the directory to your `fpath` to load it lazily:
+
+`fpath=("/path/to/hpi/repo/misc/completion/zsh/" "${fpath[@]}")` (Note: the directory, not the script `_hpi`)
+
+If your zsh configuration doesn't automatically run `compinit`, after modifying your `fpath` you should:
+
+`autoload -Uz compinit && compinit`
+
+### fish
+
+`cp ./fish/hpi.fish ~/.config/fish/completions/`, then restart your shell
