 ### 5.iv. How can I show errors or warnings in my statusline?

-[vim-airline](https://github.com/vim-airline/vim-airline) integrates with ALE
-for displaying error information in the status bar. If you want to see the
-status for ALE in a nice format, it is recommended to use vim-airline with ALE.
-The airline extension can be enabled by adding the following to your vimrc:
+You can use `ALEGetStatusLine()` to integrate ALE into vim statusline.
+To enable it, you should have in your `statusline` settings

 ```vim
-" Set this. Airline will handle the rest.
-let g:airline#extensions#ale#enabled = 1

 ```

-If you don't want to use vim-airline, you can implement your own statusline
-function without adding any other plugins. ALE provides a function for counting
-the number of problems for this purpose, named `ale#statusline#Count`.
+When errors are detected a string showing the number of errors will be shown.
+You can customize the output format using the global list `g:ale_statusline_format` where:

-Say you want to display all errors as one figure, and all non-errors as another
-figure. You can do the following:

Adriaan Zonnenberg	1f7679e619	Remove 'col' from linters where it is hardcoded to 1 (#434 ) * Remove 'col' from linters where it is hardcoded to 1 When 'col' is 1, the first column will get highlighted for no reason. It should be 0 (which is the default). In the scalac linter there was also a check about the outcome of `stridx`. It would set l:col to 0 if it was -1, and then it uses `'col': l:col + 1` to convert the outcome of `stridx` to the actual column number. This will make 'col' equals 1 when there is no match. We can remove the check because `-1 + 1 = 0`. * Remove outdated comments about vcol vcol was added as a default, and the loclists that follow these comments do not contain 'vcol' anymore Conflicts: ale_linters/elixir/dogma.vim	2017-03-31 19:01:10 +01:00
