So it seems that tui-rs doesn't like rendering my CPU bars if the height is exactly 1. It needs at least 2. I have no idea why, this is probably something weird with how I render.
This, of course, breaks when there is only one row to report (i.e. with a dual core setup in #397).
The workaround switches the gap between the CPU and mem/net parts to 0, and increases the CPU's draw height by 1, only when the height is otherwise 1 (so the draw height is now at least 2). This does have the side effect of including an extra line to the side borders, but I think it's fine.
When running without elevated permissions under macOS, sysinfo cannot
query states of processes by root user, which results in 0.0% CPU usage
for all this kind of processes (and state = Unknown).
Here we use `ps`, which has SUID, as a fallback to query CPU usages.
This can be potentially applied to other properties if needed in the
future (we'll need a proper struct and parser).
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
```
Firstly, note this currently won't affect basic mode. There is code changes due to it, but instead, we'll just display `0.0B/0.0B` instead. I'm personally not really sure if we want to get rid of it in basic mode, since it'll leave an ugly gap in that mode.
Anyways, this change is mainly for the normal mode. All this does is hide the legend entry and chart if the total SWAP drops to 0 KB. It also has a small change to do a unit check on the memory used, as well as slightly adjusting the calculation we use.
Refactors to use only heim for Linux builds. This is now much easier to do since the 0.1 version of heim works fine for ARM. This is ideal since having to rely on two separate sources of data isn't the greatest if we can avoid it.
Sysinfo is still required for macOS and Windows, though. Temperature sensors do not work for those from heim, and for some reason, networks also don't work on Windows with heim...?
My personal CPU core calculation is also currently Linux-only, and as such, I'll still rely on sysinfo for Windows and macOS for now.
This isn't really a big optimization or anything btw. Just something I wanted to try.
* feature: added signal selection for killing in unix
* feature: set default signal to 15 (TERM)
* feature: selecting kill signal number with number keys
* feature: mouse selection of kill signals
* fix: restore working previous kill dialog for win
* bug: more fixes for killing on windows
* feature: made two digit number selection only work in time window
* feature: replaced grid with scrollable list for kill signal selection
* fix: handling scrolling myself
* chore: replaced tui list with span
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
Making some small changes that would hopefully improve performance a bit.
- Remove redundant string generations for CPU data conversion
- Switch to fnv for PID hashmap and hashsets
- Use buffered reading to avoid having to store too many lines as strings
