# rtop
<div align="center">
*Another* TUI based resource monitor, this time in Rust! Currently a WIP.
</div>
## Usage
### Keybinds
- Quit: `q` or `<C-c>`
- Process navigation:
- `k` and `<Up>`: up
- `j` and `<Down>`: down
- `<C-u>`: half page up
- `<C-d>`: half page down
- `<C-b>`: full page up
- `<C-f>`: full page down
- `gg` and `<Home>`: jump to top
- `G` and `<End>`: jump to bottom
- Process actions:
- `<Tab>`: toggle process grouping
- `dd`: kill selected process or group of processes
- Process sorting:
- `c`: CPU
- `m`: Mem
- `p`: PID
- Process filtering:
- `/`: start editing filter
- (while editing):
- `<Enter>`: accept filter
- `<C-c>` and `<Escape>`: clear filter
- CPU and Mem graph scaling:
- `h`: scale in
- `l`: scale out
- `?`: toggles keybind help menu
### Mouse
- click to select process
- mouse wheel to scroll through processes
### Colorschemes
rtop ships with a few colorschemes which can be set with the `-c` flag followed by the name of one. You can find all the colorschemes in the [colorschemes folder](./colorschemes).
To make a custom colorscheme, copy one of the default ones to `~/.config/rtop/<name>.json` and load it with `rtop -c <name>`. Colorschemes PRs are welcome!
### CLI Options
```
USAGE:
rtop [FLAGS] [OPTIONS]
FLAGS:
-a, --average-cpu Show average CPU in the CPU widget.
-b, --battery Show Battery widget (overridden by 'minimal' flag).
-f, --fahrenheit Show temperatures in fahrenheit.
-h, --help Prints help information
-m, --minimal Only show the CPU, Mem, and Process widgets.
-p, --per-cpu Show each CPU in the CPU widget.
-s, --statusbar Show a statusbar with the time.
-V, --version Prints version information
OPTIONS:
-c, --colorscheme <colorscheme> Set a colorscheme. [default: default]
-i, --interfaces <interfaces> Comma separated list of network interfaces to show. Prepend an interface with '!'
to hide it. 'all' shows all interfaces. [default: !tun0]
-r, --rate <rate> Number of times per second to update the CPU and Mem widgets. [default: 1]
```
