gotop shows system information in a terminal UI. It can be configured to have
different layouts, color schemes, and widgets, and it is able to show
information from other computers.

Anything you change on the command line can be written to a config file
using the `--write-config` argument, which can then be edited further.
Just get your arguments the way you like, then run gotop again with the same
arguments and the `--write-config` flag, and gotop will persist your
options.

Colorschemes are json files; put them in the config directory (usually
~/.config/gotop/{name}.json) and load them with the `-c {name}` argument.
The keys are:

    Fg          -- int, foreground color
    Bg          -- int, background color
    BorderLabel -- int, color of widget text
    BorderLine  -- int, color of borders
    CPULines    -- array of ints for the colors of lines
    BattLines   -- array of ints for the colors of lines
    MemLines    -- array of ints for the colors of lines
    ProcCursor  -- int, color of the cursor in the process widget
    Sparklines  -- array of ints for the colors of network usage
    DiskBar     -- int, color of the disk bars
    TempLow     -- int, color used for low temperatures
    TempHigh    -- int, color used for high temperatures

For example:

    { "Fg": 7, "CPULines": [4, 3, 2, 1, 5, 6, 7, 8] }

Colorschemes are referred to by their name minus the .json suffix. More 
examples are here:

Layout files are plain text files, with widget names on rows roughly representing
a grid. The format is ROWSPAN:WIDGETNAME/COLSPAN. COLSPAN is relative to the
rest of the line, so a line saying "cpu mem/3" will give the CPU widget 25% of
the width, and the memory widget 75% of the width. ROWSPAN is the height of
the widget, so "2:cpu mem" will make the CPU widget 2 rows high, and the memory
widget 1 row high. An example is:

    2:cpu
    disk/1      2:mem/2
    temp
    2:net       2:procs

Save your layout under any file name either in the config directory or your current
directory and reference the file name with the `-l` argument. More details about 
the rules are here:

gotop can function as both a metrics exporter and viewer. As an exporter, it 
exports Prometheus metrics, and it does not handle either encryption or 
authentication, and so should be run behind a reverse proxy. When gotop is run
with the `-x` argument, gotop will export metrics on the given port. To try it,
run

    gotop -x :8884

and then from another shell, run:

    curl http://localhost:8884/metrics

To show these metrics in gotop, instead of curl run:

    gotop --remote-url http://localhost:8884/metrics 

You will see additional values in your widgets. To monitor remote machines,
run gotop on them with the `-x` export flag behind a reverse proxy such as
Caddy:

    myserver.net {
        basicauth / gtuser gtpass
        reverse-proxy /metrics http://localhost:8884
    }

and then on your local gotop:

    gotop --remote-url https://gtuser:gtpass@myserver.net/metrics

Config files, layouts, and color schemes are searched for (in order):

- In the current directory
- In $XDG_CONFIG_DIR/gotop
- In /etc/gotop (on Linux and MacOS)
