neovim/neovim#5529 merged support for Vim's partial functions, which
made nvim more strict about dictionary functions and callbacks, to
match Vim behavior.
* Add chktex linter
* Alias plaintex to tex
* Add lacheck linter
Closes#179
* Add the chktex warning code
This very useful to have when you want to suppress lint warnings with LaTeX
comments. chktex tends to be a bit noisy so this often needed.
* lacheck: Make regex less specific
To be more robust future changes in `stdin-wrapper`
This PR first and formost implements support for dot-seperate filetypes,
a very trivial change.
This closes#132
But more importantly, this PR vastly improves the test quality for
`ale#linter#Get`. It enables us to reset the state of ale's internal
linter cache, to facilitate better testing, as well as making use of
mocked linters instead of depending on linters on disk (which may
change). In addition, a dummy linter is defined to test the autoloading
behavior.
Header guards were removed from all linters as:
* A: ale won't try and load linters if they already exist in memory
* B: we can't reset state for testing if they can't be loaded again
The statusbar now keeps its state in a separate variable, in order to
avoid excess iterations. The engine now updates said variable on run,
and a new function is made available for external statusbars to call (to
avoid dependencies on internal implementation details of ale).
To keep things light, the status bar code is not loaded unless invoked
by the user or an external plugin. On the first load it will update
itself from the global loclist, after that, the engine will handle all
updates.
The external integration function, `ale#statusline#Count()`, will return
a tuple in the format [E, W] (where E is errors, W is warnings), unless
no data exists (ie, the plugin doesn't have a linter for a file or has
not run yet), in which case it returns 0/false.
