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.
Not available in main portage tree yet, see gentoo bug 649904. In
the meantime, get it from the moltonel overlay : install
layman and run layman -a moltonel before running emerge
emlop as ususal.
Install Rust using emerge rust (if you simply want to install Emlop)
or rustup (if you want the latest Rust or plan to
develop in Rust). Emlop releases should always work with portage's oldest rust version.
Cargo installs binaries into ~/.cargo/bin/, which should be in your $PATH. If you wish to
install them system-wide, edit the system $PATH or copy/symlink ~/.cargo/bin/* somewhere in
$PATH.
cargo install -f emlop
git clone https://github.com/vincentdephily/emlop
cd emlop
cargo test
cargo install -f --path .
Emlop is split into log, predict and stats subcommands, which can be abbreviated by their
first letter. This file doesn't show everything, see emlop --help and emlop <sucommand> --help
for complete and up to date usage info.
Shell autocompletion is available. If you have installed emlop manually, generate the completion
script for bash/zsh/fish with the complete subcommand.
Show log of sucessful merges and syncs:
emlop log [OPTIONS] [package]
<package> Display only packages matching <package>.
-s, --show <m,u,s,a> Show (m)erges, (u)nmerges, (s)yncs, and/or (a)ll. [default: m]
-e, --exact Match package with a string instead of a regex.
Predict merge time for current or pretended merges:
emlop predict [OPTIONS]
--limit <limit> Use the last N merge times to predict next merge time. [default: 10]
Show statistics about sucessful merges and syncs:
emlop stats [OPTIONS] [package]
<package> Show only packages matching <package>.
-s, --show <p,t,s,a> Show (p)ackages, (t)otals, (s)yncs, and/or (a)ll. [default: p]
-g, --groupby <y,m,w,d> Group by (y)ear, (m)onth, (w)eek, or (d)ay.
-e, --exact Match package with a string instead of a regex.
--limit <limit> Use the last N merge times to predict next merge time. [default: 10]
Options common to all subcommands:
-f, --from <date> Only parse log entries after <date>.
-t, --to <date> Only parse log entries before <date>.
--duration <hms,s> Format durations in hours:minutes:seconds or in seconds. [default: hms]
-F, --logfile <file> Location of emerge log file. [default: /var/log/emerge.log]
-v Show warnings (-v), info (-vv) and debug (-vvv) messages (errors are always displayed).
--color <when> Enable color (auto/always/never/y/n). [default: auto]
-h, --help Show short (-h) or detailed (--help) help.
