CHANGELOG.md

Changelog

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog.

Versioning for this project is based on Semantic Versioning. More specifically:

Pre 1.0.0 (current):

• Patch versions should aim to only contain bug fixes or non-breaking features/changes.
• Minor versions may break things.

Post 1.0.0:

• Patch versions should only contain bug fixes.
• Minor versions should only contain forward-compatible features/changes.
• Major versions may break things.

That said, these are more guidelines rather than hardset rules, though the project will generally try to follow them.

• 99d0402: Fix config detection for built-in colours.

[0.5.0] - 2020-11-20

Features

• #206: Adaptive network graphs --- prior to this update, graphs were stuck at a range from 0B to 1GiB. Now, they adjust to your current usage and time span, so if you're using, say, less than a MiB, it will cap at a MiB. If you're using 10GiB, then the graph will reflect that and span to a bit greater than 10GiB.

• #208: Mouse support for tables and moving to widgets.

• #217: (Kinda) ARM support.

• #220: Add ability to hide specific temperature and disk entries via config.

• #223: Add tree mode for processes.

  • #312: Add a tree flag to default to the tree mode.

• #269: Add simple indicator for when data updating is frozen.

• #296: Built-in colour themes.

• #309: Add a mem_as_value flag to default displaying process memory as value rather than percentage.

Changes

• #213, #214: Updated help descriptions, added auto-complete generation.

• #296: Changed how we do battery theming. We now only set high, medium, and low colours, and we deal with the ratios.

Bug Fixes

• #211: Fix a bug where you could move down in the process widget even if the process widget search was closed.

• #215: Add labels to Linux temperature values.

• #224: Implements sorting by count. It previously did absolutely nothing.

• #238: Fix being able to cause an index out-of-bounds by resizing to a smaller terminal just after the program got the terminal size, but right before the terminal started drawing.

• #238: Fixed not clearing screen before drawing, which caused issues for some environments.

• #253: Fix highlighted entries being stuck in another colour when the widget is not selected.

• #253, #266: Expanding a widget no longer overrides the widget/dialog title colour.

• #261: Fixed process names occasionally showing up as truncated, due to only using /proc/<PID>/stat as our data source.

• #262: Fixed missing thread termination steps as well as improper polling causing blocking in input thread.

• #289: Fixed the CPU basic widget showing incorrect data due to an incorrect offset when displaying the data.

[0.4.6] - 2020-08-25

Features

• #179: Show full command/process path as an option.

• #183: Added sorting capabilities to any column.

• #188: Add (estimated) memory usage values, toggle this from percent to values for processes with %.

• #196: Support searching processes by process state.

• Added WASD as an alternative widget movement system.

• #198: Allow e to also escape expanded mode.

Changes

• #181: Changed to just support stable (and newer) Rust, due to library incompatibilities.

• #182: For macOS, support $HOME/Library/Application Support instead of $HOME/.config for config files. For backwards compatibility's sake, for macOS, this will still check .config if it exists first, but otherwise, it will default to the new location.

Bug Fixes

• #183: Fixed bug in basic mode where the battery widget was placed incorrectly.

• #186: Fixed a bug caused by hitting Enter when a process kill fails, breaking future process kills.

• #187: Fix bug caused by incorrectly reading the /proc/{pid}/stats file.

[0.4.5] - 2020-07-08

• No changes in this update, just an uptick for Crates.io using the wrong Cargo.lock.

[0.4.4] - 2020-07-06

Features

• #114: Show process state per process (originally in 0.4.0, moved to later). This only shows if the processes are not merged together; I couldn't think of a nice way to show it when grouped together, unfortunately.

Changes

• #156 - Removal of the / CPU core showing in the chart. It felt clunky to use, was not really useful, and hard to work with large core counts.

  Furthermore:

  • show_disabled_data option and flag is removed.

  • Average CPU is now on by default. You can disable it via -a, --hide_avg_cpu or hide_avg_cpu = true.

  • Make highlighted CPU persist even if widget is not selected - this should help make it easier to know what CPU you are looking at even if you aren't currently on the CPU widget.

Bug Fixes

• #164 - Fixed a bug where bottom would incorrectly read the wrong values to calculate the read/write columns for processes in Linux.

• #165 - Fixed a bug where OR operations in the process query wouldn't properly for some cases.

• The process query should hopefully be a bit more usable now. There were issues with how spaces (which are treated as an AND if it was between keywords, so something like btm cpu > 0 mem > 0 would look for a process named btm with cpu usage > 0 and mem usage > 0). This has been hopefully improved.

[0.4.3] - 2020-05-15

Other

• Update sysinfo version that fixes an overflow issue.

[0.4.2] - 2020-05-11

Changes

• Automatically hide time axis labels if the widget gets too small.

• Automatically hide table gap if the widget gets too small.

Bug Fixes

• The <Space> character can be used as an "AND" again (properly) in queries. For example:

(btm cpu > 0) (discord mem > 0)

is equivalent to:

(btm AND cpu > 0) AND (discord AND mem > 0)

• #151 - Fixed an issue where if the drive I/O label didn't match any disk, the entire disk widget would display nothing.

• Display SWAP and MEM legends even if the total amount is 0 to avoid a weird blank spot in the legend.

[0.4.1] - 2020-05-05

Bug Fixes

• #146: Fixed a typo in the help menu (credit to HarHarLinks).

[0.4.0] - 2020-05-04

Features

• #58: I/O stats per process.

• #55: Battery monitoring widget.

• #134: hjkl movement to delete dialog (credit to andys8).

• #59: Alt-h and Alt-l to move left/right in query (and rest of the app actually).

• #59: Added a more advanced querying system.

Changes

• Changed default colours for highlighted borders and table headers to light blue - this is mostly to deal with Powershell colour conflicts.

• Updated the widget type keyword list to accept the following keywords as existing types:

  • "memory"
  • "network"
  • "process"
  • "processes"
  • "temperature"

• #117: Update tui to 0.9:

  • Removed an (undocumented) feature in allowing modifying total RX/TX colours. This is mainly due to the legend change.

  • Use custom legend-hiding to stop hiding legends for memory and network widgets.

  • In addition, changed to using only legends within the graph for network, as well as redesigned the legend. The old legend style can still be used via the --use_old_network_legend flag or use_old_network_legend = true config option.

  • Allow for option to hide the header gap on tables via --hide_table_gap or hide_table_gap = true.

• #126: Updated error messages to be a bit more consistent/helpful.

• #70: Redesigned help menu to allow for scrolling.

• #59: Moved maximization key to e, renamed feature to expanding the widget. Done to allow for the <Enter> key to be used later for a more intuitive usage.

Bug Fixes

• Fixed dd not working on non-first entries.

• Fixed bug where a single empty row as a layout would crash without a proper warning. The behaviour now errors out with a more helpful message.

• Fixed bug where empty widgets in layout would cause widget movement to not work properly when moving vertically.

Bug Fixes

• #14: Fixed default config paths not being read properly.

[0.2.0] - 2020-02-20

Features

• Searching in processes was added.

• The option of a config file was added. Config files follow the TOML spec. These support boot flags by default, and colour schemes.

• The capability of maximizing a widget to take up all draw space was added.

• Filtering out CPU cores on the graph/legend was added.

Changes

• Default colours were changed for better support on macOS Terminal and PowerShell.

• Rewrote and refactored how I get data to be less spaghetti. This might also have the added benefit of running better, with less duplicated logic.

• Changed how the dd dialog and help dialog look. Hopefully they'll be nicer to look at and more intuitive to use!

Bug Fixes

• #2: Fixed issues where the program would crash if the window was too small.

• Added a panic handler so terminals won't get all broken if a panic does still occur.

• Fixed some sizing issues, hopefully this means that it's still readable at smaller sizes (within reason).

• #10: Fixed scroll issue caused by resizing.

[0.1.2] - 2020-01-11

Changes

• Added a bit more complexity to how we determine column widths for tables. This should fix an issue where columns would glitch out at smaller widths, and hopefully look nicer.

Bug Fixes

• Rewrote scroll logic in tables to avoid some strange scroll behaviour I encountered where it would jump around.

• Attempt to patch a panic caused by the change in how we determine time in the data collection stage.

[0.1.1] - 2020-01-11

Features

• Tab in the processes widget will now group similarly-named processes together (as well as their total CPU and MEM usage). dd-ing this will try to kill all entries with that process name.

• A flag to enable this by default is also now available.

Bug Fixes

• Accidentally left in a bug in which the disk widget was using megabytes instead of bytes as their unit during data collection... but during data conversion for the display I treated them as bytes.

[0.1.0] - 2020-01-11

Initial release.
