# 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) - Support for multiple line selection Run `luneta -h` for help: ``` usage: luneta [options] -v --version version -q --query default query to be used upon startup -f --filter do not start interactive finder, e.g -f="pattern" --height set the maximum window height (number of lines), e.g --height 25 --color color support, e.g --color=FALSE -h --help This help information. ``` ## Installation ### Brew `brew install fbeline/luneta/luneta` ### Snap `snap install luneta` ### AUR https://aur.archlinux.org/packages/luneta Thanks to [@al1-ce](https://github.com/al1-ce) ### Precompiled binaries [Releases](https://github.com/fbeline/luneta/releases) - note: `libncurses` is required. ### Manual Installation Prerequisites: - [ldc](https://dlang.org/download.html) - [dub](https://code.dlang.org/download) - ncurses ```bash git clone https://github.com/fbeline/luneta cd luneta dub build -b release --compiler ldc2 ``` ## Usage Search a command in your shell history: ```bash fc -ln 1 | luneta ``` Checkout a git branch: ```bash git branch 2>/dev/null | luneta | sed "s/.* //" | awk '{print $1}' | xargs git checkout ``` Kill an active process: ```bash ps -e -o comm | luneta | xargs pkill ``` Refer to the [examples](/examples.md) for more. ## 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") ``` *This vimscript is a modified version of the [selecta](https://github.com/garybernhardt/selecta#use-with-vim). ## Keyboard shorcuts | Key | Action | |-----|--------| | CTRL + Space | Select line and move to the next item | | CTRL + n | next selection | | CTRL + p | previous selection | | CTRL + a | beggining of the line | | CTRL + e | end of the line | | CTRL + u | erase all the character before and after the cursor | | CTRL + d | exit | ## License GPL-2.0
