I want to comment out multiple lines at once in a YAML file. Since YAML uses # for single-line comments, is there a way to create block comments that cover several lines?
How can I efficiently add YAML comments to a block of lines without prefixing each line individually?
I had the same question about block comments in YAML. Unfortunately, YAML doesn’t support block comments like /* ... */ in other languages.
The only way is to put a # at the start of each line you want to comment out. It’s a bit tedious, but most editors support multi-line commenting shortcuts that add # to selected lines, which helps a lot.
When I needed block comments in YAML, I realized there’s no native syntax for it. You have to prefix every line with #. For example:
# line one
# line two
# line three
If you want to comment out big sections, I use my IDE’s toggle comment feature to add/remove those hashes quickly. So, while YAML lacks block comments, editor tools make this manageable.
YAML doesn’t have block comments like some other formats, so to comment multiple lines, you must use # on each line.
I once tried to find a block comment workaround but ended up relying on editor macros or plugins to automate this. Also, you can use multi-line strings or fold blocks to handle large text without commenting, depending on your use case.
