# gotop

![image](demo.gif)

Another TUI graphical activity monitor, inspired by [vtop](https://github.com/MrRio/vtop) and [gtop](https://github.com/aksakalli/gtop), this time written in [Go](https://golang.org/)!  
Built with [gopsutil](https://github.com/shirou/gopsutil), [drawille-go](https://github.com/exrook/drawille-go), and a heavily modified version of [termui](https://github.com/gizak/termui) which uses [termbox-go](https://github.com/nsf/termbox-go).


## Installation

Go compiles to a single executable so you just need to get that into your $PATH.

To download the latest binary for your OS into `/usr/bin`, you can run the [install](https://github.com/cjbassi/gotop/blob/master/install.sh) script:

```
curl https://raw.githubusercontent.com/cjbassi/gotop/master/install.sh | sudo bash
```

If you install this way, starting gotop with the `-u` flag will update if there's a newer version.

To uninstall:

```
sudo rm /usr/bin/gotop
```

Currently only tested on Arch Linux x86_64, so create an issue if the binary for your OS doesn't work or if there isn't one.


### Arch Linux

Alternatively, if you're on Arch Linux you can install the `gotop` package from the AUR.

    * `C-d` and `C-u`: up and down half a page
    * `C-f` and `C-b`: up and down a full page
    * `gg` and `G`: jump to top and bottom
* Process Sorting:
    * `c`: CPU
    * `m`: Mem
    * `p`: PID
* `<tab>`: toggle process grouping
* `dd`: kill the selected process or process group
* `<left>`/`<right>` and `h`/`l`: zoom in and out of graphs
* `?`: toggles keybind help menu

* mouse wheel to scroll Process List


## Colorschemes

A different Colorscheme can be set with the `-c` flag followed its name. You can find them in the `colorschemes` folder.
Feel free to add a new one. You can use 256 colors, bold, underline, and reverse. More info [here](https://godoc.org/github.com/nsf/termbox-go#Attribute) and [here](https://godoc.org/github.com/nsf/termbox-go#OutputMode) under 'Output256'.


## TODO

* Network Usage
    - increase height of sparkline depending on widget size
* Process List
    - memory total goes above 100%
* Disk Usage
    - color percentage based on usage
    - change bar color to white
* CPU Usage
    - support colors for more CPU cores
* general
    - add support for themes
    - copy over vtop themes
    - command line option to set polling interval for CPU and mem
    - command line updating
    - command line option to only show processes, CPU, and mem
    - zooming in and out of graphs
    - add gif
    - create a mac binary
* cleaning up code
    - termui Blocks should ignore writing to the outside area
        - Ignore writes to outside of inner area, or give error?
    - termui Blocks should be indexed at 0, and maybe change X and Y variables too
    - remove gotop unique logic from list and table
        - turn column width logic into a function
    - try to get drawille fork merged upstream
    - more documentation
    - Draw borders and label after other stuff
    - Only merge stuff in the range
    - Merge should include offset
    - Remove merge from grid buffer function, just render
    - Remove merge altogether
