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.
* First pass at optimizing ale to autoload
First off, the structure/function names should be revised a bit,
but I will wait for @w0rp's input before unifying the naming style.
Second off, the docs probably need some more work, I just did some
simple find-and-replace work.
With that said, this pull brings major performance gains for ale. On my
slowest system, fully loading ale and all its code takes around 150ms.
I have moved all of ale's autoload-able code to autoload/, and in
addition, implemented lazy-loading of linters. This brings load time on
that same system down to 5ms.
The only downside of lazy loading is that `g:ale_linters` cannot be
changed at runtime; however, it also speeds up performance at runtime by
simplfying the logic greatly.
Please let me know what you think!
Closes#59
* Address Travis/Vint errors
For some reason, ale isn't running vint for me...
* Incorporate feedback, make fixes
Lazy-loading logic is much improved.
* Add header comments; remove incorrect workaround
* Remove unneeded plugin guards
* Fix lazy-loading linter logic
Set the wrong variable....
* Fix capitialization
* Ensure that php linter pattern does not include spaces:
PHP can return errors with extra spaces like the following:
`PHP Parse error: syntax error, unexpected end of file in t.php on line 4`
* Set option locally to buffer
* Rename noErrors variable according to the project's naming convention
* Make the jsonlint pattern a little better
* Implement an option to configure the echoed message, #48
Via `g:ale_echo_msg_format` where:
- `%s` is the error message itself
- `%linter%` is the linter name
- `%severity` is the severity type
e.g
let g:ale_echo_msg_fomat = '[%linter%] [%severity%] %s'
* Add new options for defining the string used for errors in echoed
message
`g:ale_echo_msg_error_str` and `g:ale_echo_msg_warning_str`
* Change text output of some linters
Now that the echoed message can be customized, no need to add the type
to the text variable.
* Update README & documentation file
* Fix some typos
* Sort the table of options alphabetically (except echo_msg_x_str options)
* Added echo warning str option to the doc
