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]

Other commands

• complete generates shell completions
• accuracy helps analizing predictions accuracy

Installation

Using portage

emerge emlop

The ebuild is also maintained in the moltonel overlay, which you can enable using eselect-repository.

Install Rust and using portage or rustup. Make sure ~/.cargo/bin/, is in your $PATH.

From crates.io

cargo install -f emlop

From git

git clone https://github.com/vincentdephily/emlop
cd emlop
cargo test
cargo install -f --path .
