Creating a Linter Plugin

• Fork this repo to bootstrap your new linter.
• Clone it into Packages.
• Change a linter.py.
• Update the README and replace cfn-lint placeholders.
• Update messages/install.txt and replace cfn-lint placeholders.
• Open a PR in our package_control repo to make it available to others.

Additional documentation can be found at sublimelinter.com.

Updating class attributes

Template linter plugins are created with almost all of the Linter class attributes filled in with the default values. To make your new linter plugin functional, at the very least you need to do the following:

• Change the default 'selector' to include the scopes you want the linter to lint.

• Change the cmd attribute to include the executable and arguments you want to include on every run. Usually this should be a tuple like ('linter', '-fooarg', '-etc', '-'). You can also make cmd a method (or callable in python speak) which returns such a tuple.

• Change the regex attribute to correctly capture the error output from the linter.

• Change the multiline attribute to True if the regex parses multiline error messages.

Other, optional, attributes include:

• If the linter executable does not accept input via stdin, set the tempfile_suffix attribute to the filename suffix of the temp files that will be created.

• If the linter outputs errors only on stderr or stdout, set error_stream to util.STREAM_STDERR or util.STREAM_STDOUT respectively.

You should remove attributes that you do not change, as their values will be provided by the superclass. More information can be found in the docs.
