0.7.0

0.7.0 2024-03-04

Feature release: Multi-term search, config file, and many goodies

New features

• Support searching by multiple terms
  • eg emlop s -e gcc clang llvm rust
• Support configuration file
  • Located at ~/.config/emlop.toml, or whereever $EMLOP_CONFIG says
  • Example file added to repo, should be installed alongside emlop docs
  • All available config options correspond to a cli arg, which takes precedance
• Support reading gzip-compressed emerge.log.gz file
• Autodetect tmpdir using currently running emerge processes
• Assume unknown packages take 10s (overridable with --unknown) to compile instead of 0

Interface changes

• Support multiple --tmpdir arguments
• --tabs has been renamed --output=tab/columns/auto (or -ot for short)
  • Default output is now columns on tty and tab otherwise, to simplify emlop ...|cut -f... workflow
• Added --resume=either variant to resume either main or backup list
  • Passing --resume without argument is now the same as --resume either
  • Default value remains auto (use main list if currently emerging)
• --color variants renamed to (y)es, (n)o, (t)ty
• Improved inline help and error messages
  • Upgraded argument parser dependency
  • We now do our own parsing and error rendering for many args
  • Color scheme, style, and texts updated

Bug fixes and misc

• Fixed column width when --last is used
• Fixed noticing a failed/interruped merge when the emerge proces keeps going
• Ignore a performance-sensitive test during emerge
• Display elapsed time also while compiling an unknown package
• Raised MSRV to 1.71

0.6.1

Maintenance release

• Refactored tests to avoid deadlock when testing via portage
  • As a bonus, tests finish much faster
• Reduced packaged crate size by compressing image and removing unwanted files
• Routine deps update

0.6.0

0.6.0

Feature release: Improved predict command and accuracy, filter sync events, new output options,
and more.

Main changes

• predict command now reads portage's merge resume list
  • emlop p behaves the same as emerge -rOp|emlop p if a merge is currently running
  • Including geting confused when you have multiple emerge commands running
  • You can still pipe any emerge -p command into emlop p
  • See --resume to tweak the behavior
• predict command now displays the current build phase and last log line of ongoing builds
  • This usually requires root permissions
• list/stat search now also applies to sync repos, eg emlop l -ss guru
• Improved stats layout
  • Group by section (syncs/packages/total) before grouping by date
  • Each section has its specific headers and colum count
  • Display at most 3 sections (tables), separated by a newline
• Added --show option to predict, like in other subcommands
• Added --first/-N/--last/-n options to limit output
• Added --tabs option for more machine-readable output
• Added --avg=mean/median/weighted option to tweak predictions
  • mean is the original behaviour
  • median is the new default, it's more resilient against noisy data
  • weighted-{arith,median} gives more importance to recent values
• Added --starttime option to show merge start instead of merge end
• Moved --show h option value to a dedicated --headers/-H flag
  • Fixes surprising behavior when only h was specified
  • More discoverable
• Added accuracy subcommand to evaluate prediction accuracy
  • Mostly a development tool, but you might find it useful

And also

• Long args like --duration can now be abbreviated
• --color is now an alias of --color=always
• Bash completion no longer wrongly suggests -V/--version for subcommands
• Exit code on error changed to 1 for empty results and 2 for plain errors
• Various performance improvements
  • Now clearly faster than qlop in all cases
• Improved and reorganized inline help
• Use asciinema recordings in readme
• Internal stuff
  • Increased MSRV to 1.65
  • Updated github CI actions
  • Upgraded clap (triggered a lot of this release's improvements)
  • Recover from process listing errors
  • Various refactorings
  • Removed unmaintained ansi_term and sysconfig
  • New/improved benchmark tools
