Add --config-file argument to use alternate config file at runtime (#1290)
* added new CLI argument option --config-file

* pass argument and fetch alt config file if specified

* argparse argument setting update

* argument alias --cf added

* documentation update - usage of CLI argument

* fixed name-clash + unit tests

* feature test added

* #1170-alternate-config-file: Auto stash before rebase of "refs/heads/#1170-alternate-config-file"

* Update docs/advanced.md

Co-authored-by: Jonathan Wren <jonathan@nowandwren.com>

* BDD tests added

* Begin migrating/rewording --cf tests in pytest-bdd.

Uses current directory instead of deep directory structure, but requires a given for each config file referenced

* Fix issue where specifying a config-file that needs to be upgraded ended up upgrading the user config file instead

* Uncomment and rework remaining tests for pytest-bdd instead of behave

* Fix copytree for Python 3.7 (which doesn't support dirs_exist_ok)

* Minor fixes to alternative config examples

* Remove behave tests (behave is no longer in use)

* Move config file unit test to unit test dir and use pytext path fixture instead of current directory to find test data

* Use explicit "given the config exists" for copying config files instead of shoehorning in "given we use the config" twice

* Change when/when to when/and

* Clarify scenarios and fix indentation

* Confirm primary config file isn't modified when encrypting/decrypting a journal in an alternate config file

* Remove try/except on copytree since I'm no longer using the same

# Advanced Usage
## Configuration File
You can configure the way jrnl behaves in a configuration file. By
default, this is `~/.config/jrnl/jrnl.yaml`. If you have the `XDG_CONFIG_HOME`
variable set, the configuration file will be saved as
`$XDG_CONFIG_HOME/jrnl/jrnl.yaml`.
!!! note
On Windows, the configuration file is typically found at `%USERPROFILE%\.config\jrnl\jrnl.yaml`.
The configuration file is a YAML file with the following options
and can be edited with a plain text editor.
!!! note
Backup your journal and config file before editing. Changes to the config file
can have destructive effects on your journal!
- `journals`
paths to your journal files
- `editor`
if set, executes this command to launch an external editor for
writing your entries, e.g. `vim`. Some editors require special
options to work properly, see `FAQ <recipes>` for details.
- `encrypt`
if `true`, encrypts your journal using AES.
- `tagsymbols`
Symbols to be interpreted as tags. (See note below)
- `default_hour` and `default_minute`
if you supply a date, such as `last thursday`, but no specific
time, the entry will be created at this time
- `timeformat`
how to format the timestamps in your journal, see the [python docs](http://docs.python.org/library/time.html#time.strftime) for reference
- `highlight`
if `true`, tags will be highlighted in cyan.
- `linewrap`
controls the width of the output. Set to `false` if you don't want to wrap long lines.
- `colors`
dictionary that controls the colors used to display journal entries. It has four subkeys, which are: `body`, `date`, `tags`, and `title`. Current valid values are: `BLACK`, `RED`, `GREEN`, `YELLOW`, `BLUE`, `MAGENTA`, `CYAN`, `WHITE`, and `NONE`. `colorama.Fore` is used for colorization, and you can find the [docs here](https://github.com/tartley/colorama#colored-output). To disable colored output, set the value to `NONE`. If you set the value of any color subkey to an invalid color, no color will be used.
- `display_format`
specifies formatter to use, formatters available are:
`boxed`, `fancy`, `json`, `markdown`, `md`, `tags`, `text`, `txt`, `xml`, or `yaml`.
!!! note
Although it seems intuitive to use the `#`
character for tags, there's a drawback: on most shells, this is
interpreted as a meta-character starting a comment. This means that if
you type
> `jrnl Implemented endless scrolling on the #frontend of our website.`
your bash will chop off everything after the `#` before passing it to
`jrnl`. To avoid this, wrap your input into quotation marks like
this:
> `jrnl "Implemented endless scrolling on the #frontend of our website."`
Or use the built-in prompt or an external editor to compose your
entries.
### Modifying Configurations from the Command line
You can override a configuration field for the current instance of `jrnl` using `--config-override CONFIG_KEY CONFIG_VALUE` where `CONFIG_KEY` is a valid configuration field, specified in dot-notation and `CONFIG_VALUE` is the (valid) desired override value.
You can specify multiple overrides as multiple calls to `--config-override`.
!!! note
These overrides allow you to modify ***any*** field of your jrnl configuration. We trust that you know what you are doing.
#### Examples:
``` sh
#Create an entry using the `stdin` prompt, for rapid logging
jrnl --config-override editor ""
#Populate a project's log
jrnl --config-override journals.todo "$(git rev-parse --show-toplevel)/todo.txt" todo find my towel
#Pass multiple overrides
jrnl --config-override display_format fancy --config-override linewrap 20 \
--config-override colors.title green
```
### Using an alternate config
You can specify an alternate configuration file for the current instance of `jrnl` using `--config-file CONFIG_FILE_PATH` where
`CONFIG_FILE_PATH` is a path to an alternate `jrnl` configuration file.
#### Examples:
```
# Use personalised configuration file for personal journal entries
jrnl --config-file ~/foo/jrnl/personal-config.yaml
# Use alternate configuration file for work-related entries
jrnl --config-file ~/foo/jrnl/work-config.yaml
# Use default configuration file (created on installation)
jrnl
```
## Multiple journal files
You can configure `jrnl`to use with multiple journals (eg.
`private` and `work`) by defining more journals in your `jrnl.yaml`,
for example:
``` yaml
journals:
default: ~\journal.txt
work: ~\work.txt
```
The `default` journal gets created the first time you start `jrnl`
Now you can access the `work` journal by using `jrnl work` instead of
`jrnl`, eg.
``` sh
jrnl work at 10am: Meeting with @Steve
jrnl work -n 3
```
will both use `~/work.txt`, while `jrnl -n 3` will display the last
three entries from `~/journal.txt` (and so does `jrnl default -n 3`).
You can also override the default options for each individual journal.
If your `jrnl.yaml` looks like this:
``` yaml
encrypt: false
journals:
default: ~/journal.txt
work:
journal: ~/work.txt
encrypt: true
food: ~/my_recipes.txt
```
Your `default` and your `food` journals won't be encrypted, however your
`work` journal will!
You can override all options that are present at
the top level of `jrnl.yaml`, just make sure that at the very least
you specify a `journal: ...` key that points to the journal file of
that journal.
Consider the following example configuration
```yaml
editor: vi -c startinsert
journals:
default: ~/journal.txt
work:
journal: ~/work.txt
encrypt: true
display_format: json
editor: code -rw
food:
display_format: markdown
journal: ~/recipes.txt
```
The `work` journal is encrypted, prints to `json` by default, and is edited using an existing window of VSCode. Similarly, the `food` journal prints to markdown by default, but uses all the other defaults.
!!! note
Changing `encrypt` to a different value will not encrypt or decrypt your
journal file, it merely says whether or not your journal
is encrypted. Hence manually changing
this option will most likely result in your journal file being
impossible to load.
## Known Issues
### Unicode on Windows
The Windows shell prior to Windows 7 has issues with unicode encoding.
To use non-ascii characters, first tweak Python to recognize the encoding by adding `'cp65001': 'utf_8'`, to `Lib/encoding/aliases.py`. Then, change the codepage with `chcp 1252` before using `jrnl`.
