Availability of block remarks/comment's

[nielsnl68]

Hello,
i could not find an earlier post about this, i'm sure this must have been talked about many times before.

I use YAML to program code for (esphome)[www.esphome.io] for some time now. And YAML is good way to be used in this context.
But sometime I would love to block out data without removing the whole "code" block. i know you could add a # for every line but when you need a lot of line it is not that nice. Having a way to easily blockout some parts would be preferable to me.

Now i was wondering of it could be possible to think of a way to make this happen.

Option 1 could be the introducing of for example "##" that everything blocks until the second "##". The "##" should be place on a new line without any text after it. This will mean that YAML scripts are not backward compatible anymore.

like:

american:
- Boston Red Sox
- Detroit Tigers
- New York Yankees
##
# de below 4 lines are commented out
national:
- New York Mets
- Chicago Cubs
- Atlanta Braves
##

Option 2 could be that a "#" before a key, without a space between, and ended with the : will comment out all Sequence and/or mappings below it below the key. For commenting out a sequenced mapping you add the "#" direct before the "-" like #- key: value.

Like:

NormalKey: Valuepair
national:
- New York Mets
- Chicago Cubs
- Atlanta Braves
#avg: 0.278 # Batting average   # this comment out only this line.

# american:    # this will only comment out this line
- Boston Red Sox
- Detroit Tigers
- New York Yankees
 
# The following "#" comment out the whole stack block
#Stack:
