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 is heavily inspired by genlop but aims to be faster, more accurate, and more convenient. Other rewrites of Genlop exist, see COMPARISON doc.
Installation
From most stable to most recent:
From main portage tree
Sorry not available yet, waiting for the first release to ask for inclusion.
From portage overlay
If you do not have it already, install and configure layman.
Then run layman -a moltonel to add the overlay with the emlop ebuild. Then run emerge emlop as
ususal.
From source
If you do not already have Rust, install it with emerge rust or
rustup. Emlop should always work with a version of
rust available in portage, but the version from rustup might be more recent and performant.
git clone https://github.com/vincentdephily/emlop
cd emlop
cargo test
cargo install -f
If you wish to install emlop system-wide, copy or symlink ~/.cargo/bin/emlop into
/usr/local/bin/ or some other folder from your $PATH, or add ~/.cargo/bin/emlop to your
$PATH.
Usage
Emlop is split into subcommands like list or predict, which can be abbreviated by their first
letter. For a complete list of arguments (this readme doesn't list them all) see emlop -h or
emlop <sucommand> -h.

Predict merge time
Show currently emerging packages, how long they have been running, and predict how long is left:
$ emlop p
Pid 27455: ...n-exec/python3.5/emerge -O chromium 33
Pid 27848: ...on-exec/python3.5/emerge -O firefox 29
www-client/firefox 53:37 - 24
www-client/chromium 6:01:02 - 28
Estimate for 2 ebuilds (0 unknown, 52 elapsed) 6:53:47
Predict merge time from an emerge --pretend output, taking currently elapsed time into account:
$ emerge -rOp | emlop p
Pid 8799: .../emerge -O chromium firefox konqueror 1:14:11
www-client/chromium 5:49:38 - 1:10:55
www-client/firefox 53:37
kde-apps/konqueror 3:46
Estimate for 3 ebuilds (0 unknown, 1:10:55 elapsed) 5:36:06
Show merge statistics
Show total merge time, merge count, and average merge time:
