* only check `executable()` for the sub checkers once - at the top of
the script
* recapitalize `s:getPHPMDErrors` to `s:GetPHPMDErrors` errors for
style consistency
* simplify the logic in `SyntaxCheckers_php_GetLocList`
The current makeprg doesn't work with php-5.3. display_errors=0 has
disabled error outputting and error_log='' disables the error log. With
php-5.4 error_log='' is causing errors to be logged to stderr.
This patch disables the error_log and enables display_errors.
Theoretically errors are displayed on stdout, however php in mountain
lion seems to insist on outputting to stderr.
As we're now displaying errors rather than logging them to error format
has changed to no longer include 'PHP ' and I've removed duplicates.
This has been tested with PHP 5.3.13 with Suhosin-Patch (cli) (built: Jun 20
2012 17:05:20) (mountain lion) and PHP 5.4.4 (cli) (built: Jul 2 2012
16:33:50) Fedora 17
setting it to E_PARSE causes some errors to be missed - e.g.
`$a[$b][] $c;`
will not cause an error to get reported as this is classed as a compile
error, not a parse error.
This should fix#206.
* remove the public SyntasticHighlightErrors() function
* shift the above code into s:HighlightErrors(). This is called
automatically if g:syntastic_enable_highlighting is set
* to get the highlight regex we just look for a function called
Syntastic_<filetype>_GetHighlightRegex
* to force this function to be called, each error item must have the
'force_highlight_callback' key set
This code has one important functional change: now errors are *always*
highlighted if possible whereas previously they were only highlighted if
a call to SyntasticHighlightErrors was made.
running phpcs on a file which contains a parse error generates a huge
number of warnings from the phpcs library. This can freeze vim for
minutes at a time while it attempts to parse these
notices/warnings/errors.
Therefore - don't run phpcs on files which have parse errors.
PHPCS has a wide variety of commandline flags, including
support for various syntaxes. These must be configurable,
otherwise phpcs generates a high number of spurious errors for
code written to any standard other than the PEAR standard.
