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.

Internal changes

#38: Updated arg tests and added config testing.
Add MSRV, starting with 1.40.0.

[0.3.0] - 2020-04-07

Features

#20: Time scaling was added to allow users to zoom in/out based on their desired time intervals. Time markers on the charts can be hidden or automatically hidden.
#37: Automatically populate a config file if one does not exist.
#21: Basic mode added.
#51: Modularity with widget placement or inclusion added.

Changes

Removed redundant dependencies.
#17: Add colouring options to the total RX/TX labels.
#29: Added F1-F3 keys as alternatives for selecting search options
#42, #45, #35: Change the arrow used for sorting processes to work with other terminals.
#61: Search box changed to not block if the window is small.
#40: Rewrote README to be more clear and explicit.
#109: Sorting processes by name is case-insensitive.

Bug Fixes

#33: Fix bug with search and graphemes bigger than a byte crashing due to the cursor.
#41: Fix bug that caused the cursor to go off-screen while searching.
#61: Dialog boxes set to be a constant width/height.
#80: Fix bug with resizing and scrolling causing issues with tables.
#77: Fixed hidden CPU entries from being scrolled to.
#79: Fixed CPU entries being a different colour if the one above it was hidden.
#85: A div-by-zero error when the memory values were zero was fixed.

Other

Various Travis changes.
Scoop install option added.

[0.2.2] - 2020-02-26

Features

Added support for colouring the average CPU core separately in config files.
#15 - Added support for (some) named colours and RGB values in config files.

Bug Fixes

#28: Fixed broken Cargo.toml for Cargo installs.
Fixed Windows issue with shift key.
#14: Ignore certain characters in search

[0.2.1] - 2020-02-21

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.
