# Coverage.vim

For [coc.nvim](https://github.com/neoclide/coc.nvim) users, please take a look at [coc-coverage](https://github.com/ruanyl/coc-coverage)

Greatly inspired by [vim-gitgutter](https://github.com/airblade/vim-gitgutter)

A vim plugin which shows code coverage like [wallabyjs](https://wallabyjs.com/). Supports istanbul `json reporter` format:
- [istanbul](https://github.com/gotwarlost/istanbul)
- [nyc](https://github.com/istanbuljs/nyc)
- [karma-coverage](https://github.com/karma-runner/karma-coverage)
- [jest](https://github.com/facebook/jest)

> requires vim8 or neovim

### Install

```
Plug 'ruanyl/coverage.vim'
```

### How it works

This plugin uses vim8 new feature `timer_start()` to read the `<coverage-*>.json` in an interval. Whenver the file changed, it will update the signs of current buffer.

The plugin awares of signs from other plugins, for example: `syntastic`, `ale` ... But it will overwrite the signs of `gitgutter`.

### Config

```vim
" Specify the path to `coverage.json` file relative to your current working directory.
let g:coverage_json_report_path = 'coverage/coverage.json'

" Define the symbol display for covered lines
let g:coverage_sign_covered = '⦿'

" Define the interval time of updating the coverage lines
let g:coverage_interval = 5000

" Do not display signs on covered lines
let g:coverage_show_covered = 0

" Display signs on uncovered lines
let g:coverage_show_uncovered = 1
```
