pueue 2.0.0

on Rust Cargo

This release marks the second stable release of Pueue.

Shortly after releasing v1.0.0 a few short-comings of some design decisions became apparent.
This release aims to remove all those short-comings or important missing features.
Some of those changes required breaking changes of both internal APIs and datastructures, as well as the CLI interfaces and the configuration file.
Since this project sticks to SemVer, this meant that a new major release was necessary.

Hopefully, this will be the last major release for quite a while.
There are a few features planned that might introduce further breaking changes, but those will most likely need quite some time to implement (if we manage to implement them at all).

Anyhow, I'm quite pleased with the overall state of this release!
A lot of cool and convenient stuff has been added and quite a bit of internal logic has been streamlined and cleaned up.

Also a huge thanks to all contributors that helped working on this version!

Added

• Shell auto-completion value hints for some arguments (zsh and fish only).
• Introduce the rm (remove), re (restart) and fo (follow) subcommand aliases #245.
• Allow to set the amount of parallel tasks at group creation by Spyros Roum #245.
• When calling pueue without a subcommand, the status command will be called by default #247.
• Add the --group parameter to the pueue clean command #248.
• Add output for a task's log output as template parameters for callbacks #269.
• Add --lines parameter to pueue follow to only show specified number of lines from stdout before following #270.
• Notify the user if a task is added to a paused group #265.
• Notify the user that when killing whole groups, those groups are also paused #265.
• Implementation of configuration profiles #244.
  This supports multiple profiles in a single pueue.yml, which can be loaded via the --profile/-p $name flag.
• Added the shared.runtime_directory config variable for any runtime related files, such as sockets.
• XDG_CONFIG_HOME is respected for Pueue's config directory #243.
• XDG_DATA_HOME is used if the pueue_directory config isn't explicitly set #243.
• XDG_RUNTIME_DIR is used if the new runtime_directory config isn't explicitly set #243.
• The unix socket is now located in the runtime_directory by default #243.
• The format-status subcommand #213.
  This is a preliminary feature, which allows users to use external tools, such as jq, to filter Pueue's state -j output and pipe them back into format-status to display it.
  This feature will probably be removed once a proper internal filter logic has been added.
  The simplest usage looks like this: pueue status --json | jq -c '.tasks' | pueue format-status
• Show currently active commands when calling pueue wait.

Changed

• Improved memory footprint for reading partial logs.
• Always only show the last X lines of output when using pueue log without additional parameters.
• pueue parallel without arguments now also shows the groups with their current limit like pueue group. #264
• Configuration files will no longer be changed programatically #241.
• Default values for all most configuration variables have been added #241.
• Breaking changes: stderr and stdout of Pueue's tasks are now combined into a single file. #286
  This means a few things.
  • One doesn't have to filter for stderr any longer.
  • All logs are now combined in a single chronologically correct log file.
  • One can no longer filter for stderr/stdout specific output.
• Breaking changes: The group subcommand now has group add [-p $count] $name and group remove $name subcommands.
  The old group [-a,-p,-r] flags have been removed.
• Breaking changes: The configuration for groups can no longer be done via configuration file.
  This means, that groups can only be edited, created or deleted via the commandline interface.
  The amount of parallel tasks will also be reset to 1 when upgrading.

Removed

• No longer read /etc/pueue/ configuration files.
  Pueue isn't designed as a system wide service, hence this doesn't make any sense to have system wide configuration files.
• If multiple configuration files are found, they're no longer merged together.
  Instead, only the first file will be used.

Fixed

• Recover tasks from Locked state if editing fails #267
• pueue log now behaves the same for local and remote logs.
  Remote logs previously showed more lines under some circumstances.
• panic due to rogue .unwrap() when filtering for a non-existing group in pueue status.
