# Tips and Tricks This page contains tips and tricks for using `jrnl`, often in conjunction with other tools, including external editors. ## Co-occurrence of tags If I want to find out how often I mentioned my flatmates Alberto and Melo in the same entry, I run ```sh jrnl @alberto --tags | grep @melo ``` And will get something like `@melo: 9`, meaning there are 9 entries where both `@alberto` and `@melo` are tagged. How does this work? First, `jrnl @alberto` will filter the journal to only entries containing the tag `@alberto`, and then the `--tags` option will print out how often each tag occurred in this filtered journal. Finally, we pipe this to `grep` which will only display the line containing `@melo`. ## Combining filters You can do things like ```sh jrnl @fixed -starred -n 10 -to "jan 2013" --short ``` To get a short summary of the 10 most recent, favourite entries before January 1, 2013 that are tagged with `@fixed`. ## Statistics How much did I write last year? ```sh jrnl -from "jan 1 2013" -to "dec 31 2013" | wc -w ``` Will give you the number of words you wrote in 2013. How long is my average entry? ```sh expr $(jrnl --export text | wc -w) / $(jrnl --short | wc -l) ``` This will first get the total number of words in the journal and divide it by the number of entries (this works because `jrnl --short` will print exactly one line per entry). ## Importing older files If you want to import a file as an entry to `jrnl`, you can just do `jrnl < entry.ext`. But what if you want the modification date of the file to be the date of the entry in `jrnl`? Try this ```sh echo `stat -f %Sm -t '%d %b %Y at %H:%M: ' entry.txt` `cat entry.txt` | jrnl ``` The first part will format the modification date of `entry.txt`, and then combine it with the contents of the file before piping it to jrnl. If you do that often, consider creating a function in your `.bashrc` or `.bash_profile` ```sh jrnlimport () { echo `stat -f %Sm -t '%d %b %Y at %H:%M: ' $1` `cat $1` | jrnl } ``` ## Using templates !!! note Templates require an [external editor](./advanced.md) be configured. A template is a code snippet that makes it easier to use repeated text each time a new journal entry is started. There are two ways you can utilize templates in your entries. ### 1. Command line arguments If you had a `template.txt` file with the following contents: ```sh My Personal Journal Title: Body: ``` The `template.txt` file could be used to create a new entry with these command line arguments: ```sh jrnl < template.txt # Imports template.txt as the most recent entry jrnl -1 --edit # Opens the most recent entry in the editor ``` ### 2. Include the template file in `jrnl.yaml` A more efficient way to work with a template file is to declare the file in your [config file](./reference-config-file.md) by changing the `template` setting from `false` to the template file's path in double quotes: ```sh ... template: "/path/to/template.txt" ... ``` Changes can be saved as you continue writing the journal entry and will be logged as a new entry in the journal you specified in the original argument. !!! tip To read your journal entry or to verify the entry saved, you can use this command: `jrnl -n 1` (Check out [Formats](./formats.md) for more options). ```sh jrnl -n 1 ``` ## Prompts on shell reload If you'd like to be prompted each time you refresh your shell, you can include this in your `.bash_profile`: ```sh function log_question() { echo $1 read jrnl today: ${1}. $REPLY } log_question 'What did I achieve today?' log_question 'What did I make progress with?' ``` Whenever your shell is reloaded, you will be prompted to answer each of the questions in the example above. Each answer will be logged as a separate journal entry at the `default_hour` and `default_minute` listed in your `jrnl.yaml` [config file](../advanced/#configuration-file). ## Display random entry You can use this to select one title at random and then display the whole entry. The invocation of `cut` needs to match the format of the timestamp. For timestamps that have a space between data and time components, select fields 1 and 2 as shown. For timestamps that have no whitespace, select only field 1. ```sh jrnl -on "$(jrnl --short | shuf -n 1 | cut -d' ' -f1,2)" ``` ## Launch a terminal for rapid logging You can use this to launch a terminal that is the `jrnl` stdin prompt so you can start typing away immediately. ```bash jrnl --config-override editor "" ``` Bind this to a keyboard shortcut. Map `Super+Alt+J` to launch the terminal with `jrnl` prompt - **xbindkeys** In your `.xbindkeysrc` ```ini Mod4+Mod1+j alacritty -t floating-jrnl -e jrnl --config-override editor "", ``` - **I3 WM** Launch a floating terminal with the `jrnl` prompt ```ini bindsym Mod4+Mod1+j exec --no-startup-id alacritty -t floating-jrnl -e jrnl --config-override editor "" for_window[title="floating *"] floating enable ``` ## Visualize Formatted Markdown in the CLI Out of the box, `jrnl` can output journal entries in Markdown. To visualize it, you can pipe to [mdless](https://github.com/ttscoff/mdless), which is a [less](https://en.wikipedia.org/wiki/Less_(Unix))-like tool that allows you to visualize your Markdown text with formatting and syntax highlighting from the CLI. You can use this in any shell that supports piping. The simplest way to visualize your Markdown output with `mdless` is as follows: ```sh jrnl --export md | mdless ``` This will render your Markdown output in the whole screen. Fortunately, `mdless` has an option that allows you to adjust the screen width by using the `-w` option as follows: ```sh jrnl --export md | mdless -w 70 ``` If you want Markdown to be your default display format, you can define this in your config file as follows: ```yaml display_format: md # or display_format: markdown ``` For more information on how `jrnl` outputs your entries in Markdown, please visit the [Formats](./formats.md) section. ## Jump to end of buffer (with vi) To cause vi to jump to the end of the last line of the entry you edit, in your config file set: ```yaml editor: vi + -c "call cursor('.',strwidth(getline('.')))" ```
