Having build a lot on guixsd a while ago I noticed some differences in the cli-overview that I would like to present. Colorfication and arrows (=>) are used to clearly distinguish pacaur/pacman-commands from the buildprocess output. A nice thing I saw on some builds (build of qt during build of telegram-desktop) was a per build process percentage indicator located in the beginning of each line of build output like this: [ 0% ] lorem ipsum.... [ 10% ] lorem ipsum.... In addition to these two above I have an idea as well: Use the terminal-title wisely to show the progress of the whole transaction and the current running build (e.g.: "Download complete. Buildprogress 4/5: building qt" What do you think? ^ permalink raw reply [flat|nested] 6+ messages in thread

I think this is one of the reasons why we don't have colors. I am not against it, I just think it will make helping people a little harder when they provide such logs. On the other hand, if we manage to filter the colors out in the build logs somehow, this is of no concern to us. -- ng0 ^ permalink raw reply [flat|nested] 6+ messages in thread

What I proposed was not to color the logs but the output of guix (to distinguish it from the rest) telling the user what it is going to do/doing. The proposal for percentage did not include coloring. ^ permalink raw reply [flat|nested] 6+ messages in thread

Determine if the terminal is interactive [0] and filter escape codes if yes. I've used Arch, and the coloring was pleasant, but primarily I enjoyed the clear (and less buggy) progress bars. For example: $ guix pull Starting download of /tmp/guix-file.O3WsYp From http://git.savannah.gnu.org/cgit/guix.git/snapshot/master.tar.gz... ….tar.gz 1.7MiB/s 00:06 | 10.5MiB transferred The "From" line shows what is about to be downloaded, but the progress par suggests that "….tar.gz" is being downloaded. There is a lot of whitespace after that, which is weird. Also, here's a bug: copying and compiling to '/gnu/store/himp5ds1b9m0932dfzxp3gg3vvs7lxd4-guix-latest'... loading... 23.1% of 528 filesrandom seed for tests: 1475073161 loading... 99.8% of 528 files Something happens during the loading phase, and the string "random seed for tests: 1475073161" gets printed (also inserting a newline). The progress indicator cannot cope, so it starts on a new line. Also, it stops at 99.8% which is confusing. These non-color issues are more important to resolve, IMO.

Especially colors, which could help a lot (for non-Emacs terminals at least), and provide a more pleasant experience. Ludo’. ^ permalink raw reply [flat|nested] 6+ messages in thread
