Because writing your own layout system and management is just *so much
fun*. Totally.
-------------------------------------------------------------------
Moves the basic mode system over to the new drawing/widget system. In
the process, it has forced me to completely redo how we do layouts...
again. This is because basic mode has widgets that control their own
height - this means the height of the columns and rows that wrap it
are also affected by the widget's height.
The previous system, using a constraint tree and splitting draw Rects
via tui-rs' built-in constraint solver, did not support this concept
very well. It was not simple to propagate up the widths/heights
towards parents while also using tui-rs' built-in constraint solver.
In the end, it was easier to just rewrite it using another algorithm.
We now follow a process very similar to Flutter's layout system.
Relevant links to the Flutter docs are found in the code or below:
- https://flutter.dev/docs/development/ui/layout/constraints
- https://flutter.dev/docs/resources/inside-flutter#sublinear-layouts
The gist of it, however, is that we now instead a few new options for
any element in the layout tree. A node can either:
- Grow to fill remaining space
- Take up as much room as its children
- Be a specific length
Technically right now, it's not perfect, in that leaf nodes can be as
large as their children (which makes no sense), though in that case it
just treats it as an expand.

There were three bugs:
1. The click bounds calculation was incorrect. I did the silly mistake
of checking for <= bounds for the bottom and right sections of a
Rect when checking if the mouse intersected - this is WRONG.
For example, let's say you want to calculate if an x value of 5 falls
between something that starts at 0 and is 5 long. It shouldn't,
right? Because it draws from 0 to 4? But if you just did <=
Rect.right(), you would get a hit - because it just does (start +
width), so you get 5, and 5 <= 5!
So, easy fix, change all far bounds checks to <.
2. The second bug is a mistake where I accidentally did not include
bounds sets for my memory and net widgets. Instead, they set their
bounds to the underlying graph representation, which is WRONG, since
that bound gets updated on draw, and gets set to a slightly smaller
rect due to borders!
3. A slightly sneakier one. This broke my bounds checks for the CPU
widget - and it would have broken my process widget too.
The problem lies in the concept of widgets that handle multiple
"sub"-blocks internally, and how I was doing click detection
internally - I would check if the bounds of the internal Components
were hit. Say, the CPU, I would check if the internal graph was hit,
then if the internal table was hit.
But wait! I said in point 2 that a graph gets its borders updated on
draw to something slightly smaller, due to borders! And there's the
problem - it affected tables too. I was setting the bounds of
components to that of the *internal* representation - without borders
- but my click detection *needed* borders included!
Solution? Add another trait function to check bordered bounds, and
make the default implementation just check the existing bounds. For
cases like internal Components that may need it, I add a separate
implementation.
I also switched over all border bounds checks for Widgets to that,
since it's a bit more consistent.

Slightly move around the ideas of EventResult, ReturnSignalResult,
and how they all work.
The gist of it is that we now have widgets returning EventResults (and
renamed to WidgetEventResult), and the main app event handler returns
ReturnSignalResult (now named EventResult).
Also add a new signal to handle re-updating data inputs! This is needed
for the process, and any sortable/configurable widget.

Things working as of now:
- Actually drawing
- Interpolation
- Styling
|
|
|
|
In particular, moving over table-style widgets
|
|
This rips out this weird trait system I previously used for drawing
widgets, where I implemented a trait onto the Painter struct that did
the drawing. I have no idea what I was thinking back then.

Even more glue code to help glue together our layout options to our new
layout system!
Note that this PR will most likely likely break the two options:
- default_widget_type
- default_widget_count
and as such, they'll probably be deleted in a later commit.
As for why, it's since they're kinda a pain to support and don't work
well. Users can still enable default widget selection through the
layout system (which will also see a revamp in the future).

Adds F9 as an alternative kill shortcut to dd.

A large migration of documentation over to mkdocs, and some rewrites. Some stuff (install information, basic supported systems, contributors, thanks) are still staying in README.md, and CONTRIBUTING.md is essentially duplicated right now. However, stuff like configuration and key/mouse bindings are now moved to mkdocs.
Some parts are still a bit WIP - it is definitely not done (documentation never seems to be...). However, it should be "good enough" for now, and I'm much happier working with the documentation in this form than trying to scroll through a giant endless README.md file. It also works much better for adding new documentation.

Fixes two bugs causing the battery widget colours and mouse events to be broken.
|
|
Lowers the timer for multi-digit inputs in dd.
I'm going to eventually completely rewrite the input part for the entire application though, but this will do for now.
|
|
Fixes the mouse hitbox checks overextending by 1. Also reverts the bandaid fix done for #458.

This PR accomplishes two things:
1. This PR aims to add mount_filter to the config file. This allows a user to filter their disk widget entries by the mount name as well; this was particularly a problem in trying to address #431.
2. A slight rework of how the filter system works due to the need of being able to manage two potentially conflicting filter sources, since the disk widget will now potentially filter on both the disk name and the mount name.
In regards to the second point, the new behaviour is as such:
1. Is the entry allowed through any filter? That is, does it match an entry in a filter where is_list_ignored is false? If so, we always keep this entry.
2. Is the entry denied through any filter? That is, does it match an entry in a filter where is_list_ignored is true? If so, we always deny this entry.
3. Anything else is allowed.
This main (breaking) change is really the third point. This would mean that temp_filter and net_filter, when set to allow listed entries with is_list_ignored = false, are kinda... useless, as a whitelist in the scenario of being the only filter is kinda pointless. But hopefully this shouldn't be a problem...?

Rewrite of the y-axis labeling and scaling for the network widget, along with more customization. This still has one step to be optimized (cache results so we don't have to recalculate the legend each time), but will be done in another PR for sake of this one being too large already.
Furthermore, this change adds linear interpolation at the 0 point in the case a data point shoots too far back - this seems to have lead to ugly gaps to the left of graphs in some cases, because the left hand limit was not big enough for the data point. We address this by grabbing values just outside the time range and linearly interpolating at the leftmost limit. This affects all graph widgets (CPU, mem, network).
This can be optimized, and will hopefully be prior to release in a separate change.

Adds users into the process widget (for Unix-based systems). This shows only in non-grouped modes, similar to state. Search is also supported.
In addition, a quick fix to prevent users from being in grouped mode when they tried to enter tree mode while grouped.
|
|
Major update is tui-rs from 0.13 to 0.14. This change allows us to update our tables to make them look nicer!
|
|
For consistency, we now don't automatically jump to the top of the list when using a sort shortcut. This behaviour already occurred with the sort menu and sorting by mouse clicks, so this is just now more consistent (and IMO less annoying, you can also always jump to the top via gg).
|
|
Fixes sorting menus and shortcuts not syncing correctly if the sorting window is open.
|
|
Adds mouse support for sorting columns within the process widget. You can now click on the column header to sort (or invert the sort).
|
|
Ctrl-w deletes one word backwards from the current cursor location. Ctrl-h is just an alias for backspace.
|
|
Allows toggling the advanced kill menu via --advanced_kill or advanced_kill=true.
|
|
Adds colour schemes for Nord, along with a light variant.
|
|
Fixes a bug where you could make the sorting arrow disappear in the mem column if you did:
1. Go to proc widget
2. Switch to memory values from %
3. Press `m`
|
|
Adds a new option in the config file to filter out network interfaces. Also add the option to filter by whole words.
Interface follows that of the existing ones:
```toml
[net_filter]
is_list_ignored = false
list = ["virbr0.*"]
regex = true
case_sensitive = false
whole_word = false
```

so we actually know for sure where the buttons are
* feature: always display cancel button in kill signal selection
* chore: simplified as suggested in review
* fix: made scrolling in kill list more intuitive
* fix: differentiating macos from linux signals
* fix: fixed reversed kill confirmation movement
* chore: fixed unused warnings for windows
* feature: added G and gg keybindings for kill signal list
|
|
Adds the option to enable an "out of" indicator for scrollable table widgets (using --show_table_scroll_position).
|
|
Adds a new flag, --mem_as_value (and its corresponding config option, mem_as_value = true), which defaults to showing process memory values by their amount rather than percentage.
|
|
Adds collapsible trees to the tree mode for processes. These can be toggled via the + or - keys and the mouse by clicking on a selected entry.
|
|
Fixes a bug with CPU spacing on basic mode.
|
|
|
|
Adds a `--debug` flag to aid in debugging issues. This saves to `/tmp/bottom_debug.log`.
|
|
Adds persistent search settings across runs, by saving to the config file. Each process widget keeps track of it's *own* behaviour. The previous flags/options are now for *global* behaviour.
The following new behaviour is:
- Relevant flags: `--case_sensitive`, `--whole_word`, and `--regex`, will *override* the current widget's default behaviour.
- Relevant options: `case_sensitive`, `whole_word`, and `regex`, will also *override* the current widget's default behaviour.
As per before, if you set, say, `--case_sensitive`and `case_sensitive=true`, the flag always overrides.
Documentation updates will be done in #248.

Refactors tui-rs usage to the new 0.11.0 release. This release also fixes the highlighting bug from #249, and now, expanding a widget no longer overrides the widget title colour.
This commit also introduces #255, but that seems to be easy to bandaid so hopefully it will get fixed soon?
|
|
Initial refactorings and additions to support in-app config.
- Refactor our current options logic to support in-app configs. That is, we can write to a config file with our changes now.
- The default action when creating a new config file is to leave it blank. (TBD and for now, not sure on this one)
- Previously, we would set everything in a config file on startup; now we need to read from the config TOML struct whenever.
- `C` keybind is now occupied for configs.
- `no_write` option to never write to a config file.

Update how we position and generate column widths to look less terrible. This also adds truncation w/ ellipsis to the columns, and for processes, the state will automatically shrink to a short form (just a character) if there isn't enough space.
|
|
Adds a tree process view to bottom.
Currently uses a pretty jank method of column width setting, should get fixed in #225.
|
|
Fixes sorting by count being available, but doing nothing. This fix makes it sortable.
|
|
|
|
You can now filter out disks and temp sensors by name via config.
|
|
Fixes a bug where you could click on a widget when dd's dialog was open.
|
|
Fixes a bug, and also allows `Ctrl-F` and `/` to work in the sort widget.
