# navi icon [![Actions Status](https://github.com/denisidoro/navi/workflows/CI/badge.svg)](https://github.com/denisidoro/navi/actions) ![GitHub release](https://img.shields.io/github/v/release/denisidoro/navi?include_prereleases)



An interactive cheatsheet tool for the command-line.



[![Demo](https://asciinema.org/a/406461.svg)](https://asciinema.org/a/406461)



**navi** allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands. Suggested values for arguments are dynamically displayed in a list.



## Pros



- it will spare you from knowing CLIs by heart

- it will spare you from copy-pasting output from intermediate commands

- it will make you type less

- it will teach you new one-liners



It uses [fzf](https://github.com/junegunn/fzf), [skim](https://github.com/lotabout/skim), or [Alfred](https://www.alfredapp.com/) under the hood and it can be either used as a command or as a shell widget (_à la_ Ctrl-R).

  - pros: you have access to all possible subcommands and flags

- as a [shell widget](docs/installation.md#installing-the-shell-widget) for the terminal

  - pros: the shell history is correctly populated (i.e. with the actual command you ran instead of `navi`) and you can edit the command as you wish before executing it

- as a [Tmux widget](docs/tmux.md)

  - pros: you can use your cheatsheets in any command-line app even in SSH sessions

- as [aliases](docs/cheatsheet_syntax.md#aliases)

- as a [shell scripting tool](docs/shell_scripting.md)

- [auto-update repositories](docs/cheatsheet_repositories.md#auto-updating-repositories)

- auto-export cheatsheets from your [TiddlyWiki](https://tiddlywiki.com/) notes using a [TiddlyWiki plugin](https://bimlas.github.io/tw5-navi-cheatsheet/)



## Cheatsheet syntax



Cheatsheets are described in `.cheat` files that look like this:



```sh

% git, code



# Change branch

git checkout 



$ branch: git branch | awk '{print $NF}'

```



The full syntax and examples can be found [here](docs/cheatsheet_syntax.md).

- arguments are neither hardcoded nor a simple template
