sodium

Nested aliases for your shell.

Quick start

1. Install na

   go install github.com/rostrovsky/na@latest

   ...or download binary from the releases page and put it somewhere in your $PATH.

2. Set up your aliases in config file.

3. Generate autocompletions for your shell:

   • bash

     source <(na completion bash)

   • zsh

     source <(na completion zsh)

   • powershell

     Register-ArgumentCompleter -CommandName na -ScriptBlock $__naCompleterBlock
     na completion powershell | Out-String | Invoke-Expression

   • fish

     na completion fish | source

4. Use it!

   na # and then press Tab ↹ as many times as you need

Config file

Config file schema

Minimal form

# minimal form config example
aliases:
  ssh:
    dev:
      host-x: ssh user@host-x
      host-y: ssh user@host-y
    prod:
      host-a: ssh user@host-a
      host-b: ssh user@host-b
  grep:
    heron: grep -hEron --with-filename --color=always

Full form

Compared to the minimal form, in the full form:

• you must add mandatory _cmd key which contains aliased command
• you can add optional _info key that enriches autocompletion hints with description.

# full form config example
aliases:
  ssh:
    _info: aliases for SSH connections
    dev:
      _info: DEV environments aliases
      host-x:
        _info: makes ssh connection to host X on DEV env
        _cmd: ssh user@host-x
      host-y:
        _info: makes ssh connection to host Y on DEV env
        _cmd: ssh user@host-y
    prod:
      _info: PROD environments aliases
      host-a:
        _info: makes ssh connection to host A on PROD env
        _cmd: ssh user@host-a
      host-b:
        _info: makes ssh connection to host B on PROD env
        _cmd: ssh user@host-b
  grep: # _info key is completely optional though recommended
    heron:
      _cmd: grep -hEron --with-filename --color=always

Config file location

By default, na expects configuration file placed in ~/.config/sodium/.narc.yaml (or .yml).

You can override default config file location by setting SODIUM_CONFIG environment variable.

Supported shells

na supports all cobra-generated autocompletions:

• bash
• fish
• powershell
• zsh

Reserved aliases

Below aliases cannot be used due to being cobra bultins:

• completion
• help
• --help
• -h
• any alias starting with underscore _

Debug logs

If you need to see the debug logs, set SODIUM_LOG_LEVEL env variable to debug (case insensitive).
