## Description

This layer provides syntax checking feature.

## Layer Installation

checkers layer is loaded by default.

## Configuration

| Name                         | default value | description                                              |
| ---------------------------- | ------------- | -------------------------------------------------------- |
| `g:spacevim_enable_neomake`  | 1             | Use neomake as default checking tools                    |
| `g:spacevim_enable_ale`      | 0             | Use ale as default checking tools                        |
| `g:spacevim_lint_on_the_fly` | 0             | Syntax checking on the fly feature, disabled by default. |

**NOTE:** if you want to use  ale, you need:

```viml
let g:spacevim_enable_neomake = 0
let g:spacevim_enable_ale = 1
```

and if you want to use syntastic, set this two options to 0.
