Anyone mind if I look at this? It looks interesting. (@alexandrudima @jrieken)

PR welcome, although beware this is complicated.

same here.
I use monaco.editor.colorize to colorize some ruby code. It raises the error:

I am getting a similar error for this ruby file (which looks legit to me)

any workarounds for this? this issue is still present

OfekShilon · 2024-04-10T08:34:06Z

Maybe I'm missing something? The original example isn't valid ruby - the text at the first lines isn't commented and there's an extra end at the closing line. Anyway here's a smaller, valid ruby example demonstrating the same symptom:
https://microsoft.github.io/monaco-editor/playground.html?source=v0.36.0-dev.20230224#XQAAAALsAQAAAAAAAABBqQkHQ5NjdMjwa-jY7SIQ9S7DNlzs5W-mwj0fe1ZCDRFc9ws9XQE0SJE1jc2VKxhaLFIw9vEWSxW3yscw0N99wfdL6lWdZifSWhc9gCAnQP7m4UuZTiIrIS9pAX04f3NkJ4AQau3w4ptki3gIWzH16T25difg-USIlgIuHWaQW4UjFBxI-jBU9CCZvEu13dcLUzxHa2RS-cZPn3SUFjJ7GMRNa5TRRLvbbknTUUPnGnxar4EkxtMcz3UWzcPw7gwPrXA2ETDLZD6pzubSr6d8RLpF8vTYQgsoyeOHr_Z66mbCKiQdHphYNw6-4DDZJowvAFS07YRNc_AYYry6Pgx71Q5ZWjji0oU8xenjhZCQgdFNCCnXZI2PY5EFiP22l-TE_riTe3Rsjg442seSPP4HgMSS-Ahxk08IovLRCBPy0kgz3jYjovcFvf9JTPIA

It seems the problem has to do with consecutive ends. In this particular example the last end line isn't tokenized properly.
