In some situations, errors reported by `perl -c` can have multiple
listings of "at <file> line <number>". If the l:pattern is changed to
use non-greedy matching it will also match these.
For example:
```
use strict;
use DateTime;
$asdf=1;
```
Results in:
```
Global symbol "$asdf" requires explicit package name (did you forget to declare "my $asdf"?) at /Users/mgrimes/t.pl line 3, <DATA> line 1.
/Users/mgrimes/t.pl had compilation errors.
```
I am not 100% sure why `perl -c` generates errors with the extra "file
line <num>". It only happens in some versions of perl when certain
modules are used.
* The project style linter now runs while you type.
* Now the scripts for checking the project require blank lines.
* Many style issues have been found and fixed.
* If a Perl script compiles, there are only warnings and no errors
* Let the first Perl error or warning win.
Take the following example:
***
sub foo {
my $thing;
***
This might have the following messages when we compile it:
Missing right curly or square bracket at warning.pl line 7, at end of
line
syntax error at warning.pl line 7, at EOF
warning.pl had compilation errors.
With the current behaviour, we just get a "syntax error" message, which
isn't all that helpful. With this patch we get "Missing right curly or
square bracket".
* Fix variable scope and pattern matching syntax
* Use named variable to enhance clarity when matching Perl output
* Add more tests for Perl linter
* Remove unnecessary parens
* Simplify check for pattern match
"-X Disables all warnings regardless of use warnings or $^W". See
"perldoc perlrun" or http://perldoc.perl.org/perlrun.html
With the current defaults, warnings are squashed. For example:
$ perl -X -Mwarnings -c -e'BEGIN { 42 + undef }'
-e syntax OK
$ perl -Mwarnings -c -e'BEGIN { 42 + undef }'
Use of uninitialized value in addition (+) at -e line 1.
-e syntax OK
So, it's not clear from the current defaults whether Ale wants to remove
warnings or enable them. As it stands, it's trying to do both and the
disabling appears to win.
This commit enables warnings by default.
* Remove 'col' from linters where it is hardcoded to 1
When 'col' is 1, the first column will get highlighted for no reason. It
should be 0 (which is the default).
In the scalac linter there was also a check about the outcome of
`stridx`. It would set l:col to 0 if it was -1, and then it uses
`'col': l:col + 1` to convert the outcome of `stridx` to the actual
column number. This will make 'col' equals 1 when there is no match. We
can remove the check because `-1 + 1 = 0`.
* Remove outdated comments about vcol
vcol was added as a default, and the loclists that follow these comments
do not contain 'vcol' anymore
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
* 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
