Highlighting in custom SublimeLinter plugin

Question

I started writing a plugin for SublimeLinter and so far the linting itself is working. However, I haven't managed to get highlighting to work. Since my linter (which is actually a compiler) does not output column, I'd be happy if the failing lines would be highlighted.

The relevant portion in linter.py reads like this:

regex = (
  r'Error in script \".+?\" on line (?P<line>\d+) -- aborting creation process'
)
multiline = True
line_col_base = (1, 1)

An example error from the linter executable looks like this:

Invalid command: Naem
Error in script "/Users/testuser/Desktop/lint-test.nsi" on line 5 -- aborting creation process

I don't know how SublimeLinter can make use of the error message, so I'd be happy getting the line part right for now.

Edit: According to the comment below I tried to make use of near, but due to scarce documentation and no examples, I still haven't managed to find a solution. My updated regex pattern:

regex = (
  r'Invalid command\: (?P<near>\w+)'
  r'Error in script \"(.+?)\" on line (?P<line>\d+) -- aborting creation process'
)

Even though this would only capture misspelled commands, an answer could make it easier for me to understand how to properly capture output.

SublimeLinter specifies "near" as parameter if plugin does not return column. Can you capture "Naem" in near group ? http://www.sublimelinter.com/en/latest/linter_attributes.html#regex Or just override the extract method: http://www.sublimelinter.com/en/latest/linter_methods.html#split-match — Dawid Gosławski, Sep 01 '15 at 20:20
@alkuzad Thanks for the tip, that should work for invalid commands. Will give it a try on the weekend! — idleberg, Sep 07 '15 at 07:06

Here's what I ended up using:

syntax = 'nsis'
    regex = (
        r'(?P<message>[^\r?\n]+)\r?\n'
        r'(?P<error>Error) in script "[^"]+" on line (?P<line>\d+) -- aborting creation process'
    )
    multiline = True
    error_stream = util.STREAM_STDOUT
    line_col_base = (1, 1)

If I remember correctly, it was the missing line-breaks.
