Syntastic is a syntax checking plugin for Vim that runs files through external
|
|
|
|
syntax checkers and displays any resulting errors to the user. This can be done
|
|
|
|
on demand, or automatically as files are saved. If syntax errors are detected,
|
|
|
|
the user is notified and is happy because they didn't have to compile their
|
|
|
|
code or execute their script to find them.

1. Errors are loaded into the location list for the corresponding window.
|
|
|
|
2. When the cursor is on a line containing an error, the error message is echoed in the command window.
|
|
|
|
3. Signs are placed beside lines with errors - note that warnings are displayed in a different color.
|
|
|
|
4. There is a configurable statusline flag you can include in your statusline config.
|
|
|
|
5. Hover the mouse over a line containing an error and the error message is displayed as a balloon.
|
|
|
|
6. (not shown) Highlighting errors with syntax highlighting. Erroneous parts of lines can be highlighted.

Installing syntastic is easy but first you need to have the [pathogen][1]
|
|
|
|
plugin installed. If you already have [pathogen][1] working then skip
|
|
|
|
[Step 1](#step1) and go to [Step 2](#step2).
|
|
|
|
|

|

|
<a name="step1"></a>
|
|
|
|
|
|
|
|
### 2.1\. Step 1: Install pathogen.vim
|
2012-09-03 12:43:05 -04:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
First I'll show you how to install Tim Pope's [pathogen][1] so that it's easy to
|
|
|
|
install syntastic. Do this in your terminal so that you get the `pathogen.vim`
|
|
|
|
file and the directories it needs:
|
|
|
|
```sh
|
|
|
|
mkdir -p ~/.vim/autoload ~/.vim/bundle; \
|
|
|
|
curl -so ~/.vim/autoload/pathogen.vim \
|
|
|
|
https://raw.github.com/tpope/vim-pathogen/master/autoload/pathogen.vim
|
|
|
|
```
|
|
|
|
Next you *need* to add this to your `~/.vimrc`:
|
|
|
|
```vim
|
|
|
|
execute pathogen#infect()
|
|
|
|
```
|
2012-09-03 12:43:05 -04:00
|
|
|
|
2014-02-03 01:23:00 -05:00
|
|
|
<a name="step2"></a>
|
|
|
|
|
|
|
|
### 2.2\. Step 2: Install syntastic as a pathogen bundle
|
2012-09-03 12:43:05 -04:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
You now have pathogen installed and can put syntastic into `~/.vim/bundle` like
|
|
|
|
this:
|
|
|
|
```sh
|
|
|
|
cd ~/.vim/bundle
|
|
|
|
git clone https://github.com/scrooloose/syntastic.git
|
|
|
|
```
|
2012-09-03 12:43:05 -04:00
|
|
|
Quit vim and start it back up to reload it, then type:
|
2014-03-04 04:13:43 -05:00
|
|
|
```vim
|
|
|
|
:Helptags
|
|
|
|
```
|
|
|
|
If you get an error when you do this, then you probably didn't install
|
|
|
|
[pathogen][1] right. Go back to [Step 1](#step1) and make sure you did the following:
|
2012-09-03 12:43:05 -04:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
1. Created both the `~/.vim/autoload` and `~/.vim/bundle` directories.
|
|
|
|
2. Added the `call pathogen#infect()` line to your `~/.vimrc` file
|
|
|
|
3. Did the `git clone` of syntastic inside `~/.vim/bundle`
|
2012-09-03 12:43:05 -04:00
|
|
|
4. Have permissions to access all of these directories.

## 3\. FAQ

2012-03-01 11:54:05 -05:00
|
|
|

__Q. I installed syntastic but it isn't reporting any errors...__
|
2012-03-01 11:54:05 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
A. The most likely reason is that none of the syntax checkers that it requires
|
2014-03-04 07:29:13 -05:00
|
|
|
is installed. For example: by default, python requires either `flake8` or
|
2014-03-04 04:13:43 -05:00
|
|
|
`pylint` to be installed and in your `$PATH`. To see which executables are
|
|
|
|
supported, look at the [wiki][3]. Note that aliases do not work; the actual
|
|
|
|
executables must be available in your `$PATH`. Symbolic links are okay though.
|
|
|
|
You can see syntastic's idea of available checkers by running `:SyntasticInfo`.
|
2012-03-01 11:54:05 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
Another reason it could fail is that either the command line options or the
|
|
|
|
error output for a 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. The `perl` checker has stopped working...__
|
|
|
|
|
|
|
|
A. The `perl` checker runs `perl -c` against your file, which in turn
|
|
|
|
__executes__ any `BEGIN`, `UNITCHECK`, and `CHECK` blocks, and any `use`
|
|
|
|
statements in your file (cf. [perlrun][10]). This is probably fine if you
|
2014-03-04 04:13:43 -05:00
|
|
|
wrote the file yourself, but it's a security problem if you're checking third
|
2014-03-03 02:43:14 -05:00
|
|
|
party files. Since there is currently no way to disable this behaviour while
|
|
|
|
still producing useful results, the checker is now disabled by default. To
|
|
|
|
(re-)enable it, set `g:syntastic_enable_perl_checker` to 1 in your vimrc:
|
|
|
|
```vim
|
2014-03-04 04:13:43 -05:00
|
|
|
let g:syntastic_enable_perl_checker = 1
|
2014-03-03 02:43:14 -05:00
|
|
|
```
|
2013-02-14 09:58:47 -05:00
|
|
|
|
2013-06-20 15:08:34 -04:00
|
|
|
__Q. I run a checker and the location list is not updated...__
|
2013-02-21 21:04:25 -05:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
A. By default the location list is changed only when you run the `:Errors`
|
2014-01-20 03:29:06 -05:00
|
|
|
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:
|
2013-05-27 03:20:44 -04:00
|
|
|
```vim
|
2014-03-04 04:13:43 -05:00
|
|
|
let g:syntastic_always_populate_loc_list = 1
|
2013-05-27 03:20:44 -04:00
|
|
|
```
|
2013-02-21 21:04:25 -05:00
|
|
|
|
2013-05-28 03:26:30 -04:00
|
|
|
__Q. How can I pass additional arguments to a checker?__
|
2013-02-21 21:04:25 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
A. Almost all syntax checkers use the `makeprgBuild()` function. Those checkers
|
|
|
|
that do can be configured using global variables. The general form of the
|
2014-03-04 04:13:43 -05:00
|
|
|
global `args` variables is `syntastic_<filetype>_<checker>_args`.
|
2013-02-21 21:04:25 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
So, If you wanted to pass "--my --args --here" to the ruby mri checker you
|
|
|
|
would add this line to your vimrc:
|
2013-05-27 03:20:44 -04:00
|
|
|
```vim
|
2014-03-04 04:13:43 -05:00
|
|
|
let g:syntastic_ruby_mri_args = "--my --args --here"
|
2013-05-27 03:20:44 -04:00
|
|
|
```
|
2013-02-21 21:04:25 -05:00
|
|
|
|
|
|
|
See `:help syntastic-checker-options` for more information.
|
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
__Q. Syntastic supports several checkers for my filetype - how do I tell it
|
|
|
|
which one(s) to use?__
|
2013-02-10 11:51:02 -05:00
|
|
|
|
|
|
|
A. Stick a line like this in your vimrc:
|
2013-05-27 03:20:44 -04:00
|
|
|
```vim
|
2014-03-04 04:13:43 -05:00
|
|
|
let g:syntastic_<filetype>_checkers = ['<checker-name>']
|
2013-05-27 03:20:44 -04:00
|
|
|
```
|
2013-02-10 11:51:02 -05:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
To see the list of supported checkers for your filetype look at the
|
|
|
|
[wiki][3].
|
2013-02-10 11:51:02 -05:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
e.g. Python has the following checkers, among others: `flake8`, `pyflakes`,
|
|
|
|
`pylint` and a native `python` checker.
|
2013-02-10 11:51:02 -05:00
|
|
|
|
|
|
|
To tell syntastic to use `pylint`, you would use this setting:
|
2013-05-27 03:20:44 -04:00
|
|
|
```vim
|
2014-03-04 04:13:43 -05:00
|
|
|
let g:syntastic_python_checkers = ['pylint']
|
2013-05-27 03:20:44 -04:00
|
|
|
```
|
2013-02-10 11:51:02 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
Some filetypes, like PHP, have style checkers as well as syntax checkers. These
|
|
|
|
can be chained together like this:
|
2013-05-27 03:20:44 -04:00
|
|
|
```vim
|
2014-03-04 04:13:43 -05:00
|
|
|
let g:syntastic_php_checkers = ['php', 'phpcs', 'phpmd']
|
2013-05-27 03:20:44 -04:00
|
|
|
```
|
2013-02-10 11:51:02 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
This is telling syntastic to run the `php` checker first, and if no errors are
|
|
|
|
found, run `phpcs`, and then `phpmd`.
|
2013-02-10 11:51:02 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
__Q. How can I jump between the different errors without using the location
|
|
|
|
list at the bottom of the window?__
|
2012-09-05 05:13:30 -04:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
A. Vim provides several built in commands for this. See `:help :lnext` and
|
|
|
|
`:help :lprev`.
|
2012-09-05 05:13:30 -04:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
If you use these commands a lot then you may want to add shortcut mappings to
|
|
|
|
your vimrc, or install something like [unimpaired][2], which provides such
|
|
|
|
mappings (among other things).
|
2012-03-01 11:54:05 -05:00

2013-05-28 03:26:30 -04:00

|
__Q. A syntax checker is giving me unwanted/strange style tips?__
|
2012-12-05 18:33:40 -05:00
|
|
|
|
2014-01-20 03:29:06 -05:00
|
|
|
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 [wiki][3] to see what
|
|
|
|
options are available.
|
2013-04-29 02:24:32 -04:00
|
|
|
|
2014-03-04 04:13:43 -05:00
|
|
|
Alternatively, you can use `g:syntastic_quiet_messages` to filter out the
|
|
|
|
messages you don't want to see. e.g. To turn off all style messages:
|
|
|
|
```vim
|
|
|
|
let g:syntastic_quiet_messages = { "type": "style" }
|
|
|
|
```
|
|

A. There is no safe way to handle that situation automatically, but you can
|
|
|
|
work around it:
|

|
|
|
|
|
|
|
```vim
|
|
|
|
nnoremap <silent> <C-d> :lclose<CR>:bdelete<CR>
|
|
|
|
cabbrev <silent> bd lclose\|bdelete
|
|
|
|
```

Syntastic aims to provide a common interface to syntax checkers for as many
|
|
|
|
languages as possible. For particular languages, there are, of course, other
|
|
|
|
plugins that provide more functionality than syntastic. You might want to take
|
|
|
|
a look at [jedi-vim][7], [python-mode][8], or [YouCompleteMe][9].
