I’m not familiar with that language, but I went and checked and, as of now, MikroTik doesn’t appear to be listed on the Prismjs website language list. I believe that Prismjs is the sole way that syntax highlighting works in Obsidian aside from possibly plugins. But maybe you are talking about adding the syntax highlighting some other way. I had a similar request here:
Since MAXScript was recently added as a supported language after I requested it on GitHub, I am very much looking forward to when Obsidian upgrades to v1.25.0 or greater of Prismjs. That being said, I have no clue whether that means the syntax highlighting will immediately work within Obsidian, as I am unsure whether every language gets ported. But I can hope! Edit: I just checked the new 0.12.19 insider build of Obsidian and it is currently using Prismjs 1.24.1, if I am understanding the developer interface correctly. Anyways in case you were considering requesting MikroTik support, I am happy to tell you that, after my request on the Prismjs GitHub, it only took about a day for a commit, and then less than a half month before it was merged, so it is definitely worth giving it a shot. Good luck!
@andre-m-faria No problem. I should clarify that I was talking about the quick turnaround for my request of MAXScript support. You would just need to make a request on the Prismjs GitHub page asking for MicroTik support. They are very responsive. Sorry if my wording was confusing. Good luck!
