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 ergonomic. Other rewrites of Genlop exist, see COMPARISON.
Not available yet, ask in gentoo bug 649904 ;)
If you do not have layman already, install and configure it.
Then run layman -a moltonel to add the overlay with the emlop ebuild. Then run emerge emlop as
ususal.
If you do not have Rust already, install it with emerge rust or
rustup. Emlop should always work with the latest
version of rust from 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
This installs emlop into ~/.cargo/bin/, which should be in your $PATH. If you wish to install
emlop system-wide, edit the system $PATH or copy/symlink ~/.cargo/bin/emlop somewhere in
$PATH.
Emlop is split into subcommands like list or predict, which can be abbreviated by their first
letter. This file doesn't show everything, see emlop -h and emlop <sucommand> -h for complete
and up to date usage info.
Show merge date, merge time, and package name:
