# cadmus
Shell Scripts to Facilitate Effective Note Taking

## Introduction

Essentially I ~~used to~~ have a dozen shell scripts in `~/bin` that I use to capture notes,
this is an attempt to wrap them into a single script and then have aliases to make them quick to access.

## Philosophy

-  ****<span style="color:rgb(90,210,90);font-family:Courier New,Courier, monospace,serif;">cadmus</span>**** will take the notes directory from the global variable `CADMUS_NOTES_DIR`
    - The Actual work will be done by subscripts denoted by `description.bash`
        - The subscripts will take the note directory as an argument so they are portable and modular
    - The Arguments will be shifted and then all passed down to subfunctions
        - I'll just need to be careful that loose arguments aren't dangerous
- Be a Front end to tie together different scripts and tools
- Don't replicate work other people have done.
- Plain Text, Open Source.
- Be Modular
    - Pipe in input, output goes to STDOUT
    - Leave Aliases and piping to the user
        - See [Recommended Aliases](#recommended-aliases)

## Installation

To install, satisfy [the dependencies](#Dependencies) and do something like this:

```bash
cd ~/DotFiles

if [[ -d ".git" ]]; then
    echo "Adding Submodule";
    git submodule add https://github.com/RyanGreenup/cadmus
else echo "Cloning Repository";
    git clone https://github.com/RyanGreenup/cadmus
fi

stow -t $HOME -S cadmus
```

## Usage


It's all Menu driven so just follow the diagram to do what you need.

![Mindmap of Program Flow](./usage.svg "Diagram of the flow of the script")

### Assumptions

It is assumed that:

1. notes are:
    1. *Markdown* files with a `.md` extension
    2. Underneath `~/Notes`
    3. Recoll updates it's index on the fly
        * `~/Notes` will need to be indexed by *Recoll* so the results will show up.
2. You're going to use [Kitty](https://sw.kovidgoyal.net/kitty/)
    * You could either change the source or use anoter terminal that supports
      calling functions with `--`, e.g. `kitty -- nvim`
3. SSD
    * I use an SSD and some scripts are pretty inefficient (like `grep | cut |
      xargs find` to avoid creating a variable), I don't know if things like
      would work on a HDD.
4. SystemD
    * or atleast have `tmpfs` mounted at `/dev/shm` ([See the Arch Wiki: tmpfs][tmpfs]) [^wpdtmpfs]
5. I use [*Fish*] and *Oh My Fish* ([*OMF*]) as my default shell, this means `basename $SHELL` is `fish` for
   me and even though this is written in `bash` maybe that could cause issues.
    * Try [*Fish*] for a while, it's quite good, when you need to test something
      it's easy to temporarily jump back with `exec zsh`.
    * This should only matter for `cadmus find` where the use of [*Fish*] mmeans
      that results can be highlighted, I cannot get this to work with `bash` or
      `zsh` and I don't know why.
        * I wonder if this would work for [*nushell*]???
