## Supported Languages and Tools
This plugin supports the following languages and tools. All available
tools will be run in combination, so they can be complementary.

If your tool can read from stdin or you have code to suggest which is good,
support can be happily added for more tools.
## Usage
Once this plugin is installed, while editing your files in supported
languages and tools which have been correctly installed,
this plugin will send the contents of your text buffers to a variety of
programs for checking the syntax and semantics of your programs. By default,
linters will be re-run in the background to check your syntax when you open
new buffers or as you make edits to your files.
This plugin offers a variety of global flags for turning options on or off,
all of which are given defaults and described in the [flags](plugin/ale/aaflags.vim)
file. Linting on open, setting of signs, populating the loclist, and so forth may
all be configured as desired.
### Selecting Particular Linters
By default, all available tools for all supported languages will be run.
If you want to only select a subset of the tools, simply create a
`g:ale_linters` dictionary in your vimrc file mapping filetypes
to lists of linters to run.
```vim
let g:ale_linters = {
\ 'javascript': ['eslint'],
\}
```
For all languages unspecified in the dictionary, all possible linters will
be run for those languages, just as when the dictionary is not defined.
Running many linters should not typically obstruct editing in Vim,
as they will all be executed in separate processes simultaneously.
This plugin will look for linters in the [`ale_linters`](ale_linters) directory.
Each directory within corresponds to a particular filetype in Vim, and each file
in each directory corresponds to the name of a particular linter.
