## Code Conventions

### Style Guide

- `test` > `[...]`
- `&&`/`||` > `and`/`or`
- Conditionals
  - For simple conditionals use `&&`/`||`
    - Ex: `test -n "$foo" && echo "foo is not empty"`
    - Ex: `foo || bar || baz`
  - For anything more complex use `if`, `else`, and `else if`
- Piping > command substitution (only when convenient, i.e no extra commands)

### Naming Conventions

- Everything should be in `snake_case`.
- Anything exposed to the user (variables, files, functions) should begin with `tide_`.
- If the user isn't meant to interact with it from the commandline, prepend an underscore.

Examples:

- `set -l split_pwd`
- `set -U tide_right_prompt_items`
- `_tide_detect_os.fish`
- `_tide_print_item`

#### Specific Naming Conventions

- Items begin with `_tide_item_`
- Subcommands begin with `_tide_sub_`

## Makefile

Pretty self explanatory.

- `make all`
- `make fmt`
- `make lint`
- `make install`
- `make test`

In general, just run `make` to do everything.

### Specifics

- Code linting is done via [`fish --no-execute`][].
- Markdown and Yaml linting is done via the [Mega-Linter][] action.

- Markdown and Yaml formatting is done via [Prettier][].
