# vis-spellcheck
A spellchecking lua plugin for the [vis editor](https://github.com/martanne/vis).
## Installation
1. Download `spellcheck.lua` or clone this repository into your plugin directory
2. Load the plugin in your `visrc.lua` with `require('plugins/vis-spellcheck')`
## Usage
+ To enable highlighting of misspelled words press `<Ctrl-w>e` in normal mode.
+ To disable highlighting press `<Ctrl-w>d` in normal mode.
+ To toggle highlighting press `<F7>` in normal mode.
+ To correct the word under the cursor press `<Ctrl+w>w` in normal mode.
+ To ignore the word under the cursor press `<Ctrl+w>i` in normal mode.
+ To add the word under the cursor to the user dictionary press '<Ctrl+w>a' in normal mode.
## Configuration
The module table returned from `require(...)` has some configuration options:
* `cmd`: cmd that is passed to popen() and must return word corrections in Ispell format.
* default: `enchant -d %s`
* `list_cmd`: cmd that is passed to `popen()` and must output a list of misspelled words.
* default: `enchant -l -d %s`
* `default_lang`: The name of the used dictionary if the opened file does not specify one. The selected language is inserted in the cmd-strings at `%s`.
* default: `$LANG` or `en_US`
* `typo_style`: The style string with which misspellings should be highlighted when using the _full viewport_ method
* default: `fore:red`
* `check_tokens`: A table mapping all token names we consider for spellchecking to true
* default: `{[vis.lexers.STRING]=true, [vis.lexers.COMMENT]=true, [vis.lexers.DEFAULT]=true}`
* `disable_syntax_awareness`: Disable the syntax aware spellchecking and use always _full viewport_
* default: `false`
A possible configuration could look like this:
spellcheck = require(...)
spellcheck.cmd = "aspell -l %s -a"
spellcheck.list_cmd = "aspell list -l %s -a"
spellcheck.default_lang = "de_DE"
Changing language during runtime:
:set spelllang en_US
