I was compiling my blog page and I got an error:

[11ty] Problem writing Eleventy templates: (more in DEBUG output)

Digging a bit deeper… and deeper, I found a bug.

So basically when I have a bash script that tries to get the length of an array with this syntax ${#array[@]}, and the Templating Engine for 11ty thinks that {\#...} (yes I did comment it out because it broke the patch) is part of its syntax.

I created a small patch [not a solution] for it. I might work on fixing the bug in the Engine at a later date. For now, if you’re experiencing the same bug, install the patched version from my Github v2 Bash Patch.
