# badavi

[![Build Status](https://github.com/isbadawi/badavi/workflows/CI/badge.svg)](https://github.com/isbadawi/badavi/actions)

`badavi` is a vi-like terminal mode text editor, implemented in C and using the

[`termbox`](https://github.com/tomas/termbox) library to draw to the terminal.

It's meant to be a learning exercise and fun project to hack on rather than a

serious day-to-day editor, although who knows where it'll end up.

### Features supported so far

* Normal, insert, and visual modes.

* Motions -- `h`, `j`, `k`, `l`, `0`, `$`, `^`, `{`, `}`, `b`, `B`, `w`, `W`,

`e`, `E`, `G`, `g_`, `ge`, `gE`, `gg`, `%`, and more. Motions can be prefixed

with an optional count.

* `:` commands -- `:w [path]`, `:wq`, `:q`, `:e path` and more.

* Split windows with `:split` (horizontal) and `:vsplit` (vertical). You can

navigate between them with ` hjkl`, resize the current window with

` +` and ` -`, and equalize the layout with ` =`.

* Delete (`d`), change (`c`) and yank (`y`) operators, which can be applied to

any of the motions, or the visual mode selection. (Text objects aren't

implemented yet). The affected region is saved into the unnamed register, used

by `p` to paste text. Named registers from `a` to `z` are also implemented, and

can be specified by prefixing the operator (or `p`) with `"a` through `"z`.

* Undo (`u`) and redo (``) (only single-level for now, unlike vim).

* `ctags` support -- on startup badavi looks for a tags file called `tags` in

the current directory (`'tags'` option not supported yet). The `:tag` command

jumps to the specified tag, and `` jumps to the tag of the word under

the cursor. `` and `:tag` can be used to walk up and down the tag stack.

The `-t` command line option can also be passed in to start editing at the

given tag, as in e.g. `badavi -t main`.

* A small subset of the options are implemented. You can manipulate them with

`:set`, `:setlocal` and `:setglobal`. These commands accept a similar syntax

as vim, e.g. `:set number`, `:set number!`, `:set nonumber`, `:set number?`,

etc. Options can be read from a file with `:source path`. At startup a file

called `~/.badavimrc` is sourced.

* Search forwards with `/`, backwards with `?`. Standard POSIX regexes are

used, so the syntax is not exactly the same as vim's. For instance, word

boundaries are specified with `[[:<:]]` and `[[:>:]]` instead of `\<` and

`\>`. `n` and `N` can be used to cycle through matches. `*` and `#` can be

used to search forwards or backwards for the next occurrence of the word

under the cursor. Searching is a motion, so it works with the operators. The

`'incsearch'` and `'hlsearch'` options are also implemented.

### Building

Just run `make`.
