Now that stable has less 443-1, the dependency is no longer needed, and the patch can be used as-is. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

Erm, 436-1, which luckily doesn't change the conclusion. :P -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Bug#407278: better stdin patch for zless
The attached patch enables zless to correctly view standard input without changing its behavior in other cases. There is still, however, one remaining problem - the patch depends on a functionality introduced in less 429-1 and I am not sure how to sanely express such a dependency, given that gzip merely suggests less. Any suggestions? diff -ur gzip-1.3.12/zless.1 gzip/zless.1 --- gzip-1.3.12/zless.1 2009-08-09 22:39:40.0 +0200 +++ gzip/zless.1 2009-08-10 02:02:46.641941863 +0200 @@ -8,7 +8,7 @@ .I Zless is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy terminal.

- tell about it the docs/man
- patch zless like eg:
! #!/bin/sh
! PATH="/usr/bin:$PATH"; export PATH
! v=`less --version`
! v=${v#* }
! v=${v%%[ [:cntrl:]]*}
! if [ $v -lt 429 ]; then
! LESSOPEN="|gzip -cdfq %s"; export LESSOPEN
! else
! LESSOPEN="|-gzip -cdfq %s"; export LESSOPEN
! fi
! exec less "$@"
