Running Custom Checks

Scrutinizer allows you to run custom analysis commands on each inspection. These commands are run in addition to other checks you have configured.

Custom checks run in our regular build environment and are just regular shell commands that produce one of our supported output formats like checkstyle. A custom command can either be some script you have written or can be an open-source tool for which we do not have any special integration yet.


In the build environment, your code is checked out at ~/build which is also the working directory by default.

If you write your own scripts, you would typically iterate over all files in this directory and then invoke your scanning logic for each file. More sophisticated tools might need additional passes over the files, but it depends on what you plan to check.

          - command: # your custom check script.
              file:   # The output filename
              format: 'general-checkstyle'     # The supported format by Scrutinizer

If you have custom output file in your command, you need to specify the file path in the file option. Otherwise you can also leave out the file option, in this case, the result is expected to be sent to STDOUT instead. If you still want to show progress output in the latter case, make sure to send it to STDERR.


The output of the command is expected to be checkstyle xml file with the following structure:

<?xml version="1.0" encoding="UTF-8"?>
<checkstyle version="1.0.0">
    <file name="/path/to/code/myfile.php">
        <error line="2"  message="msg1" source="Ruleset.RuleName"/>
        <error line="20"  message="msg2" source="Generic.Constant"/>
        <error line="47"  message="msg3" source="ScopeIndent"/>
        <error line="47" message="msg4" source="Format.MultipleAlignment"/>
        <error line="51" message="msg5" source="Comment.FunctionComment"/>

the source attribute can be formatted as Ruleset.RuleName or simply RuleName

Installing Dependencies

If your custom command requires some set-up before it can perform its checks, you can either let it do this set-up itself, or move these commands to the dependencies section. The latter is generally preferable:

                command: npm install /plugin
