Description Peter Oliver 2021-04-28 22:47:24 UTC
Description of problem:
Colour is missing in some places when using less.

Version-Release number of selected component (if applicable):
575-2.fc34

How reproducible:
Always, but not in all places in a given file.

Steps to Reproduce:
1. ack foo [this is piped to less]
2. ack --nopager foo [this goes straight to the terminal]
3. Compare the outputs

Actual results:
Some of the colour is missing when piped to less.

Expected results:
Both look the same.

Additional info:
I tried this with the latest release, 581.2, and the bug was gone.

Comment 1 Rob Foehl 2021-05-04 07:28:49 UTC
Hit the same issue, with grep output going entirely missing due to its use of \e[K line-clearing sequences.  See https://github.com/gwsw/less/issues/140 for details.
