+1 I just encountered the same experience

For reference and the benefit of people Googling how to configure a script and regex linter, here is a full example (using sass-lint):

.arcconfig file:

{
"linters": {
    // snip ...
    "sass": {
          "type": "script-and-regex",
          "include": "(\\.scss$)",
          "script-and-regex.script": "sh -c 'sass-lint -v \"$0\" || true'",
          "script-and-regex.regex": "(^((?P<file>.+): line (?P<line>[0-9]+), col (?P<col>[0-9]+), (?P<severity>[^\\-]*) - (?P<message>.*) \\((?P<name>[a-z\\-]+)\\))$)m"
    }
}

I also encounter issues configuring the script and regex linter.
However, I use regex101 to test my regex, so I know that works.
If I remove the || true exit code workaround, I see that the right commands are issued, with the right stdout, so that works as well.

Putting it all together, I'm always met with [OKAY] No lint warnings..

Is there a way to debug arc lint?
arc lint --trace only prints execution times, not what output it got.

Hi @maccath Should the configuration file in .arclint file or .arconfig file.

I am trying for eslint in arc.

{
  "linters": {
    "javascript": {
      "type": "eslint",
      "include": "(\\.js$)",
      "script-and-regex.script": "sh -c 'eslint ./frontend/app/components/app-rule-engine/**/**.js'",
      "script-and-regex.regex": "(^((?P<file>.+): line (?P<line>[0-9]+), col (?P<col>[0-9]+), (?P<severity>[^\\-]*) - (?P<message>.*) \\((?P<name>[a-z\\-]+)\\))$)m"
    }
  }
}

This is my configuration but i'm still getting errors

Hey guys,

I use checkstyle-7.7-all.jar to check my java code, the output put is like this:

Starting audit...

can anyone teach me how to write script-and-regex.regex?

I'm having problems with script-and-regex too. I have asked in the community forum but without luck. I’m trying to add phpstan to the arc lint workflow, as explained in the documentation, but I’m unable to capture the error message. Here are my files:

.arclint

…
“phpstan”: {
“type”: “script-and-regex”,
“include”: “(\\.php$)”,
“script-and-regex.script”: “sh -c 'phpstan analyse -l 0 -c var/build/phpstan.neon --no-progress --errorFormat=raw \”$0\" || true’",
“script-and-regex.regex”: “/^(?P<name>):(?P<line>):(?P<message>.*)$/m”
},
…

Example of error message:

$>sh -c ‘phpstan analyse -l 0 -c var/build/phpstan.neon --no-progress --errorFormat=raw “$0” || true’ ‘src/AppBundle/Model/Articulos/ArticuloDocnet.php’

/private/var/www/ws/src/AppBundle/Model/Articulos/ArticuloDocnet.php:36:AppBundle\Model\Articulos\ArticuloDocnet::__construct() does not call parent constructor from Aicrag\Util\Produccion\Articulo.

When I run arc lint it’s always saying no lint warnings. I tried without the || true and it raises an exception.

I tried with the simplest valid regex shown in documentation (/^(?P<message>.*)$/m) and it finds the error in that file, but then all the other files (that doesn’t have any error) make phpstan crash saying memory consumption. I have memory_limit=2G, so I don’t think it’s a memory problem. Maybe the regex with an empty string is failing.

What could be wrong?
