Markdown syntax checking for continous integration?

Question

Short story: I'm using Markdown to write a novel. Long story is here. In this site I typo-check the text using a Perl module (which I also developed), but I'd like to check MD syntax too. However, most markdown tool seem to be too lenient on errors, letting go stuff like this

This is an *error
This would be [another error](

Besides, there is no "check-only" option that returns false when there's an error, so that it can be used in continuous integration tests. The only one that balks out in this stuff is maruku. Kramdown, pandoc, marked, markdown (for nodejs), all of them let it go without a glitch. Question is, is there a markdown syntax validator or checker in any language I can use easily in CI? Or should I go with maruku, despite being considered obsolete by his authors?

Answer 1

As pointed out in this answer, "it is impossible to write "invalid" markdown only markdown that wont do what you want it to." Every string is valid markdown.

You could, however define a subset of markdown that excludes markdown like the examples you mentioned in the question, and modify an existing parser to adhere to that subset.
