* Add column number to perlcritic linting output
This returns the column number of the perlcritic error so that ale can
show the column in addition to the line where perlcritic found an error.
* Add perlcritic configuration for rule names
This adds a configuration setting so that the name of the perlcritic
rule is shown [Rule::Name] after the error message.
This is useful to lookup the rule failure.
* Add a vader test for perlcritic#GetCommand
"-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.
