README
# luneta [](https://travis-ci.org/fbeline/luneta) [](https://snapcraft.io/luneta)
Luneta is an interactive command-line filter that can be applied to any list, e.g.,
`cat $(ls | luneta)`
In this example, a list of files and folders are passed to luneta, which opens an interactive screen that allows users to fuzzy search through it. After an item gets selected luneta writes it to the stdout.
In short, it provides a convenient way to filter the data before passing it downstream.
> (list) stdin -> luneta (interactive filter) -> stdout (selected value)
Although luneta was originally created to be used as a command-line tool, it can be integrated in other applications, e.g., [Vim](#Use-with-Vim).
## Characteristics
- Fast
- Small (~1mb binary)

## Use with Vim
Just paste the code bellow in your `.vimrc` to use luneta as your file seaching tool.
```
" Run a given vim command on the results of fuzzy selecting from a given shell
" command. See usage below.
function! LunetaCommand(choice_command, vim_command)
try
let output = system(a:choice_command . " | luneta ")
catch /Vim:Interrupt/
" Swallow the ^C so that the redraw below happens; otherwise there will be
" leftovers from luneta on the screen
endtry
redraw!
if v:shell_error == 0 && !empty(output)
exec a:vim_command . ' ' . output
endif
endfunction
" Find all files in all non-dot directories starting in the working directory.
" Fuzzy select one of those and open the selected file.
nnoremap e :call LunetaCommand("find . -type f", ":e")
nnoremap v :call LunetaCommand("find . -type f", ":vs")
nnoremap s :call LunetaCommand("find . -type f", ":sp")
```
For better results is recommended to use tools like
[ag](https://github.com/ggreer/the_silver_searcher),
[rg](https://github.com/BurntSushi/ripgrep),
[ack](https://beyondgrep.com/), etc.
```
nnoremap e :call LunetaCommand("ag . --silent -l", ":e")
nnoremap v :call LunetaCommand("ag . --silent -l", ":vs")
nnoremap s :call LunetaCommand("ag . --silent -l", ":sp")
```
