After a bit too long of a delay I’ve finally published version 0.5 of robotframework-lint. I’m officially calling this beta software now, and it’s actually quite close to production-ready. All it really needs is a bit more real-world use.

One of the biggest changes is that rules can be configured. For example, one new rule checks for lines that are greater than 100 characters. If that threshold doesn’t work for you, you can set your own threshold with the --configure option. The --configure option accepts a string of the form ”<rule name>:value”.

For example, to configure the LineTooLong rule to flag a warning if a line exceeds 80 characters instead of the default 100 you would use it like this:

$ rflint --configure LineTooLong:80 

Along with this change comes a small handful of new rules, some of which were contributed by Guy Kisel. Guy also gave some input into the configurable rule feature. Thanks, Guy!

  • LineTooLong
  • FileTooLong
  • TrailingBlankLines
  • TooManySteps (provided by guykisel)
  • TooManyTestCases (provided by guykisel)

tip: to see the documentation for a rule, use the --verbose option along with the --list option (eg: rflint --list --verbose). The formatting is a little wonky, which we’ll fix in a later release.

Other than that, there were a few bug fixes, and a new feature added to allow rule-writers to have access to the raw text in case data you wanted to check was being thrown away or altered by the parsing process.

Getting rflint

I love feedback!

If you are using robotframework-lint, or are considering using it, or have decided not to use it, I’d love to hear from you.


A huge thank-you to my current employer, Echo Global Logistics ( who generously allows me to work on this project as part of my day job.

Thank you also to Guy Kisel who has submitted some new rules.
