When trying to open a cue sheet file with less, the user only gets the following text instead of the .cue file contents: ++ WARN: could not retrieve file info for `<filename>.bin': No such file or directory ++ WARN: init failed The problem is that /usr/bin/lesspipe wrongly assumes that .cue files would belong to .bin or .raw files. It then calls 'cd-info --no-header --no-device-info $1' on it, which leads to the above message. The typical use case rather is a .cue file that corresponds to a FLAC or MP3 file, or even a .cue without any additional binary file. The solution is to remove "*.cue" from the file name check in line 164 of /usr/bin/lesspipe (Version 457 of sys-apps/less). This allows opening .cue files directly (which are normal text files anyway), but still allows usage of cd-info when .bin or .raw file areb opened directly.
(In reply to Kuli from comment #0) you really can't say "the typical use case". it might be your typical use case. that said, it works fine for me: $ less 'TRON- Legacy.cue' REM DATE 2010 REM DISCID 430EC217 REM COMMENT "ExactAudioCopy v1.0b1" PERFORMER "Unknown Artist" ... i'm using dev-libs/libcdio-0.90 over here which means cd-info does: $ cd-info --no-header --no-device-info TRON-\ Legacy.cue cd-info: Error in automatically selecting driver for input TRON- Legacy.cue. $ echo $? 1 you must post `emerge --info` with all of your bug reports, as well as version information for each package that you're using (like less & cdinfo).
Okay, maybe using .cue files for FLAC and MP3 files is not *the* typical use case, but it's a quite common use case. Currently, less only works for use cases where a corresponding .bin or .raw file exists. In all other cases, it fails. So even if only 10 % of the users don't use .bin files together with cue sheets, then it fails for 10 % of the users. I would call that a bug. And I have the strong believe that the percentage is much higher. If we remove *.cue from the file check, then everybody still can use less with the cd-info output by simply executing 'less file.bin' instead of 'less file.cue'. Since cue sheets are simple text files, and less is a text viewer, it makes pretty much sense to let less show the text contents if the user wants that. I'd assume that lesspipe has its usage in such cases where less can't display contents otherwise, e.g. as for the .bin file.

i already fixed this upstream while working on bug 285507 and it is part of the libcdio-0.90 release. that's why it works fine for me. 0.83 is known to be broken, but that's how it goes. once 0.90 goes stable, it'll fix it for you too.
Ah, perfect! I didn't know about the other bug. Thanks a lot!
