Package: numdiff Version: 5.9.0-1 Severity: wishlist Tags: upstream While using numdiff for comparing across a bulk of results files I came up with some wishes which I have shared with Paolo and we decided to cement them in an official bug report.
I was whining about "clutter" in the output which could have been reduced in favor of more concise diff summary. Here is an extract from our correspondence: Me: - 0 is == 0.0000000000, so why not just to print 0 in those cases? ;) - too many lines why not instead of (changing for demo numbers not necessarily making sense ;) ) Sum of all absolute errors: 0.0000000000 Sum of the major absolute errors: 0.1123456677 ... give smth like 0 Sum of all absolute errors 0.1123456677 Sum of the major absolute errors - and if I add -b make it nice one line (may be with better abbreviations) sum_abs=0 sub_maj_abs=0.11 ... ? - Another cool feature could be if those could be just output as a json record, so I could pipe it into some other tool (e.g. our new https://github.com/pyout/pyout). E.g. with getting a stream of records { 'filename1': 'blah', 'filename2': 'blah-a', 'Sum of all absolute errors': 0, ... } then I could build some nice view alike of "dstat" tool to visualize resources consumption which just would go through files, and have a common header, and then all those numbers underneath, e.g. #compar #result max_abs max_rel ... file1..file2 12 8 3.9e-07 1.08e-04 ... file3..file4 23 - .... which would give me a super nice overview across files ;) Paolo: I strongly favor introducing a variant of the -S summary, say -J that outputs a JSON file. This makes aggregating multiple test results and integration in CI workflows easy. Changing the output of the current -S or adding a -S -b probably breaks existing use cases. -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (600, 'unstable'), (300, 'experimental'), (100, 'unstable-debug'), (100, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.14.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages numdiff depends on: ii dpkg 1.19.0.4 ii install-info 6.5.0.dfsg.1-1 ii libc6 2.26-2 numdiff recommends no packages. numdiff suggests no packages. -- no debconf information
