# [`readline-vim`][] Upgrade [Readline][] from [`vi`][] to [Vim][]. [`readline-vim`][] generates [Readline][] macros that provide [Vim][] [motions][], [operators][] and [text objects][] (that are useful on a single line). [`readline-vim`]: https://git.rcrnstn.net/rcrnstn/readline-vim [Readline]: https://en.wikipedia.org/wiki/Readline [`vi`]: https://en.wikipedia.org/wiki/vi [Vim]: https://en.wikipedia.org/wiki/Vim [motions]: https://vimhelp.org/motion.txt.html [operators]: https://vimhelp.org/motion.txt.html#operator [text objects]: https://vimhelp.org/motion.txt.html#text-objects ## Background [Readline][] is a library that provides line-editing for interactive command-line programs. It is used in a great many places, including shells such as [Bash][] (where it originated) and [REPL][]s such as [Python][] or [Octave][]. Using [`rlwrap`][], Readline can even be used with programs that doesn't have built in support for it, such as Matlab (as in `lrwrap -a matlab -nodesktop -nosplash`). These factors make it fairly ubiquitous. Readline can be configured with an `inputrc` file, usually placed at `~/.inputrc`. Readline uses [Emacs][]-like key bindings by default. If you're a Vim fan though, you probably use its `vi` mode, activated by `set editing-mode vi` in the configuration or through some mechanism in the containing program, such as Bash's `set -o vi`. If you *are* a Vim fan though, this has the potential of landing you in a sort of [uncanny valley][] since (Readline's) `vi` (mode) does not include the many improvements contained in Vim that you have come to rely on, mainly [text objects][]. ## Usage Clone the repository ```sh git clone https://git.rcrnstn.net/rcrnstn/readline-vim cd readline-vim ``` and append the output to your `~/.inputrc` ```sh ./readline-vim >> ~/.inputrc ``` ## Similar projects - [`bash-surround`](https://github.com/liloman/bash-surround) Defines the macros manually and therefore "only" provides 234 of them, missing some functionality. The instructions are Bash centric, although it uses general Readline macros. - [Athame](https://github.com/ardagnir/athame) Patches Readline to route keystrokes through an actual Vim process. Also provides patches for [Zsh][]. This means that whatever your local Vim supports, Athame supports (including plugins)! Can be a little unreliable if your local Vim has a ton of plugins, especially if they interact with the terminal in non-obvious ways. - [`readline-vim`](https://github.com/thlorenz/readline-vim) Exclusive to [Node.js][] [`readline`][Node.js `readline`] and only defines `vi` bindings, not Vim.
