EMerge LOg Parser
Emlop parses emerge logs (as generated by portage, the Gentoo package manager) to yield useful info like merge history and merge time prediction.
It draws inspiration from genlop and qlop but aims to be faster, more accurate, and more ergonomic, see COMPARISON.
Usage
Emlop is split into commands. Command names and arguments can be abbreviated, and shell completion is available. See emlop --help
and emlop <sucommand> --help
for complete and up to date usage info.
Common options
All commands share these arguments, affecting parsing and output:
OPTIONS:
-F, --logfile <file> Location of emerge log file. [default: /var/log/emerge.log]
-v Increase verbosity (can be given multiple times).
-h, --help Show short (-h) or detailed (--help) help.
FILTER:
-f, --from <date> Only parse log entries after <date>.
-t, --to <date> Only parse log entries before <date>.
FORMAT:
-H, --header Show table header
--utc Parse/display dates in UTC instead of local time
--tabs Separate columns using tabs instead of spaces
--duration <format> Output durations in different formats. [default: hms]
--date <format> Output dates in different formats. [default: ymdhms]
--color <when> Enable color (auto/always/never/y/n). [default: auto]
List merges, unmerges, and rsyncs with log
Log-specific options:
FILTER:
<package> Show only packages matching <package>.
-e, --exact Match package with a string instead of a regex.
-s, --show <m,u,s,a> Show (m)erges, (u)nmerges, (s)yncs, and/or (a)ll. [default: m]
-N, --first <num> Show only the first <num> entries.
-n, --last <num> Show only the last <num> entries.
Estimate how long a merge with take with predict
Predict-specific arguments:
OPTIONS:
--tmpdir <dir> Location of portage tmpdir. [default: /var/tmp]
--resume <source> Use auto, main, backup, or no portage resume list [default: auto]
FILTER:
-s, --show <e,m,t,a> Show (e)emerge processes, (m)erges, (t)otal, and/or (a)ll. [default:
emt]
-N, --first <num> Show only the first <num> entries.
-n, --last <num> Show only the last <num> entries.
STATS:
--limit <num> Use the last <num> merge times to predict durations. [default: 10]
--avg <fn> Select function used to predict durations. [default: median]
Show aggregated statistics with stats
Stats-specific arguments:
FILTER:
<package> Show only packages matching <package>.
-e, --exact Match package with a string instead of a regex.
-s, --show <p,t,s,a> Show (p)ackages, (t)otals, (s)yncs, and/or (a)ll. [default: p]
STATS:
-g, --groupby <y,m,w,d> Group by (y)ear, (m)onth, (w)eek, or (d)ay.
--limit <num> Use the last <num> merge times to predict durations. [default: 10]
--avg <fn> Select function used to predict durations. [default: median]
