__Q. I installed syntastic but it isn't reporting any errors ...__
|
||||
### Q. I installed syntastic but it isn't reporting any errors...
|
||||
|
||||
A. The most likely reason is that the syntax checker that it requires isn't installed. For example: python requires either `flake8`, `pyflakes` or `pylint` to be installed and in `$PATH`. To see which executable is required, just look in `syntax_checkers/<filetype>.vim`. Note that aliases do not work; the actual executable must be available in your `$PATH`. Symbolic links are okay.
|
||||
|
||||
Another reason it could fail is that the error output for the syntax checker may have changed. In this case, make sure you have the latest version of the syntax checker installed. If it still fails then create an issue - or better yet, create a pull request.

|
||||
### Q. Recently some of my syntax checker options have stopped working...
|
||||
|
||||
A. The options are still there, they have just been renamed. Recently, almost all syntax checkers were refactored to use the new `syntastic#makeprg#build()` function. This made a lot of the old explicit options redundant - as they are now implied. The new implied options usually have slightly different names to the old options.

__Q. How can I pass additional arguments to a checker?__
|
||||
### Q. I run a chacker and the location list is not updated...
|
||||
|
||||
A. By default, the location list is changed only when you run the `:Errors` command, in order to minimise conflicts with other plugins. If you want the location list to always be updated when you run the checkers, add this line to your vimrc:
|
||||
```vim
|
||||
let g:syntastic_always_populate_loc_list=1
|
||||
```
|
||||
|
||||
### Q. How can I pass additional arguments to a checker?
|
||||
|
||||
A. Almost all syntax checkers use the `syntastic#makeprg#build()` function. Those checkers that do can be configured using global variables. The general form of the global args variables are:
|
||||
|
||||
`syntastic_[filetype]_[subchecker]_args`
|
||||
```vim
|
||||
syntastic_[filetype]_[subchecker]_args
|
||||
```
|
||||
|
||||
So, If you wanted to pass "--my --args --here" to the ruby mri checker you would add this line to your vimrc:
|
||||
|
||||
`let g:syntastic_ruby_mri_args="--my --args --here"`
|
||||
```vim
|
||||
let g:syntastic_ruby_mri_args="--my --args --here"
|
||||
```
|
||||
|
||||
See `:help syntastic-checker-options` for more information.
|
||||
|
||||
__Q. Syntastic supports several checkers for my filetype - how do I tell it which one(s) to use?__
|
||||
### Q. Syntastic supports several checkers for my filetype - how do I tell it which one(s) to use?
|
||||
|
||||
A. Stick a line like this in your vimrc:
|
||||
|
||||
`let g:syntastic_<filetype>_checkers=['<checker-name>']`
|
||||
```vim
|
||||
let g:syntastic_<filetype>_checkers=['<checker-name>']
|
||||
```
|
||||
|
||||
To see the list of checkers for your filetype, look in `syntax_checkers/<filetype>/`.
|
||||
|
||||
e.g. Python has the following checkers: `flake8`, `pyflakes`, `pylint` and a native `python` checker.
|
||||
|
||||
To tell syntastic to use `pylint`, you would use this setting:
|
||||
|
||||
`let g:syntastic_python_checkers=['pylint']`
|
||||
```vim
|
||||
let g:syntastic_python_checkers=['pylint']
|
||||
```
|
||||
|
||||
Some filetypes, like PHP, have style checkers as well as syntax checkers. These can be chained together like this:
|
||||
|
||||
`let g:syntastic_php_checkers=['php', 'phpcs', 'phpmd']`
|
||||
```vim
|
||||
let g:syntastic_php_checkers=['php', 'phpcs', 'phpmd']
|
||||
```
|
||||
|
||||
This is telling syntastic to run the `php` checker first, and if no errors are found, run `phpcs`, and then `phpmd`.

||||

||||
__Q. How can I jump between the different errors without using the location list at the bottom of the window?__
|
||||
### Q. How can I jump between the different errors without using the location list at the bottom of the window?
|
||||
|
||||
A. Vim provides several built in commands for this. See `:help :lnext` and `:help :lprev`.
|
||||
|
||||
If you use these commands a lot then you may want to add shortcut mappings to your vimrc, or install something like [unimpaired](https://github.com/tpope/vim-unimpaired) - which provides such mappings (among other things).

|

### Q. A syntax checker is giving me unwanted/strange style tips?
|
||||
|
||||
A. Some filetypes (e.g. php) have style checkers as well as syntax checkers. You can usually configure the options that are passed to the style checkers, or just disable them. Take a look at the syntax checker integration file (e.g. `syntax_checkers/php.vim`) to see what options are available.
