# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [0.5.0] - Unreleased
## [0.4.6] - Unreleased
### Features
- [#179](https://github.com/ClementTsang/bottom/pull/179): Show full command/process path as an option.
- [#183](https://github.com/ClementTsang/bottom/pull/183): Added sorting capabilities to any column.
### Changes
- Added `WASD` as an alternative widget movement system.
- Changed to just support stable (and newer) Rust, due to library incompatibilities.
- 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](https://github.com/ClementTsang/bottom/pull/183): Fixed bug in basic mode where the battery widget was placed incorrectly.
- [#186](https://github.com/ClementTsang/bottom/pull/186): Fixed a bug caused by hitting `Enter` when a process kill fails, breaking future process kills.
- [#187](https://github.com/ClementTsang/bottom/pull/187): Fix bug caused by incorrectly reading the `/proc/{pid}/stats` file.
## [0.4.5] - 2020-07-08
- No changes here, just an uptick for Crates.io using the wrong Cargo.lock.
## [0.4.4] - 2020-07-06
### Features
- [#114](https://github.com/ClementTsang/bottom/pull/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](https://github.com/ClementTsang/bottom/issues/156) - Removal of the `/` CPU core showing in the chart. It felt clunky to use, was not really useful, and hard to work with 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](https://github.com/ClementTsang/bottom/issues/164) - Fixed a bug where bottom would incorrectly read the wrong values to calculate the read/write columns for processes in Linux.
- [#165](https://github.com/ClementTsang/bottom/issues/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:
```bash
(btm cpu > 0) (discord mem > 0)
```
is equivalent to:
```bash
(btm AND cpu > 0) AND (discord AND mem > 0)
```
- [#151](https://github.com/ClementTsang/bottom/issues/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](https://github.com/ClementTsang/bottom/pull/146): Fixed a typo in the help menu (credit to [HarHarLinks](https://github.com/HarHarLinks)).
## [0.4.0] - 2020-05-04
### Features
- [#58](https://github.com/ClementTsang/bottom/issues/58): I/O stats per process.
- [#55](https://github.com/ClementTsang/bottom/issues/55): Battery monitoring widget.
- [#134](https://github.com/ClementTsang/bottom/pull/134): `hjkl` movement to delete dialog (credit to [andys8](https://github.com/andys8)).
- [#59](https://github.com/ClementTsang/bottom/issues/59): `Alt-h` and `Alt-l` to move left/right in query (and rest of the app actually).
- [#59](https://github.com/ClementTsang/bottom/issues/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](https://github.com/ClementTsang/bottom/issues/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](https://github.com/ClementTsang/bottom/pull/126): Updated error messages to be a bit more consistent/helpful.
- [#70](https://github.com/ClementTsang/bottom/issues/70): Redesigned help menu to allow for scrolling.
- [#59](https://github.com/ClementTsang/bottom/issues/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.
### Development changes
- [#38](https://github.com/ClementTsang/bottom/issues/38): Updated arg tests and added config testing.
- Add MSRV, starting with 1.40.0.
## [0.3.0] - 2020-04-07
### Features
- [#20](https://github.com/ClementTsang/bottom/issues/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](https://github.com/ClementTsang/bottom/issues/37): Automatically populate a config file if one does not exist.
- [#21](https://github.com/ClementTsang/bottom/issues/21): Basic mode added.
- [#51](https://github.com/ClementTsang/bottom/issues/51): Modularity with widget placement or inclusion added.
### Changes
- Removed redundant dependencies.
- [#17](https://github.com/ClementTsang/bottom/issues/17): Add colouring options to the total RX/TX labels.
- [#29](https://github.com/ClementTsang/bottom/issues/29): Added `F1-F3` keys as alternatives for selecting search options
- [#42](https://github.com/ClementTsang/bottom/issues/42), [#45](https://github.com/ClementTsang/bottom/issues/45), [#35](https://github.com/ClementTsang/bottom/issues/35): Change the arrow used for sorting processes to work with other terminals.
- [#61](https://github.com/ClementTsang/bottom/issues/61): Search box changed to not block if the window is small.
- [#40](https://github.com/ClementTsang/bottom/issues/40): Rewrote README to be more clear and explicit.
- [#109](https://github.com/ClementTsang/bottom/issues/109): Sorting processes by name is case-insensitive.
### Bug Fixes
- [#33](https://github.com/ClementTsang/bottom/issues/33): Fix bug with search and graphemes bigger than a byte crashing due to the cursor.
- [#41](https://github.com/ClementTsang/bottom/issues/41): Fix bug that caused the cursor to go off screen while searching.
- [#61](https://github.com/ClementTsang/bottom/issues/61): Dialog boxes set to be a constant width/height.
- [#80](https://github.com/ClementTsang/bottom/issues/80): Fix bug with resizing and scrolling causing issues with tables.
- [#77](https://github.com/ClementTsang/bottom/issues/77): Fixed hidden CPU entries from being scrolled to.
- [#79](https://github.com/ClementTsang/bottom/issues/79): Fixed CPU entries being a different colour if the one above it was hidden.
- [#85](https://github.com/ClementTsang/bottom/pull/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](https://github.com/ClementTsang/bottom/issues/15) - Added support for (some) named colours and RGB values in config files.
### Bug Fixes
- [#28](https://github.com/ClementTsang/bottom/issues/30): Fixed broken Cargo.toml for Cargo installs.
- Fixed Windows issue with shift key.
- [#14](https://github.com/ClementTsang/bottom/issues/14): Ignore certain characters in search
## [0.2.1] - 2020-02-21
### Bug Fixes
- [#14](https://github.com/ClementTsang/bottom/issues/11): 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](https://github.com/ClementTsang/bottom/issues/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](https://github.com/ClementTsang/bottom/issues/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.
