|
melonbar - A concurrent, hackable bar/panel for X written in Go.
|
|
|
|
|
|
|
|
|
|
## INSTALLATION
|
|
|
|
`go get github.com/onodera-punpun/melonbar`
|
|
|
|
`melonbar` depends on Go 1.9 or newer.
|
|
|
|
|
|
## USAGE
|
|
|
|
So the idea is that this bar is very "easy" to configure by just
|
|
modifying the source code, à la suckless.
|
|
|
|
Users can modify, configure and create new "blocks" in `blocks.go`.
|
|
and configure the position, width and font of the bar in `main.go`.
|
|
|
|
|
|
## CREATING BLOCK FUNCTIONS
|
|
|
|
On top of each block function you should run `bar.initBlock()`, this
|
|
is where most of the configuration happens. Here is a short
|
|
explanation of each parameter from left to right:
|
|
|
|
* The name of the block, this is gets used as the name of the block
|
|
map key. (`string`)
|
|
* The initial string the block should display. (`string`)
|
|
* The width of the block. (`int`)
|
|
* The aligment of the text, this can be `'l'` for left aligment, `'c'`
|
|
for center aligment `'r'` for right aligment and `'a'` for absolute
|
|
center aligment. (`rune`)
|
|
* Additional x offset to further tweak the location of the text.
|
|
(`int`)
|
|
* The foreground color of the block in hexadecimal. (`string`)
|
|
* The background color of the block in hexadecimal. (`string`)
|
|
|
|
You can also additionally specify mousebindings using:
|
|
|
|
```go
|
|
block.actions["buttonN"] = func() {
|
|
// Do stuff.
|
|
}
|
|
```
|
|
|
|
|
|
---
|
|
|
|
Everything that should not be ran in a loop should of course be
|
|
specified before the `for` loop. For example setting up a connection
|
|
to `mpd`.
|
|
|
|
If you want something to only be done *after* the very first loop - an
|
|
example of this would be not waiting for a workspace change event, but
|
|
immediately checking the current workspace - use:
|
|
|
|
```go
|
|
init := true
|
|
for {
|
|
if !init {
|
|
// Things you only want to do after the first loop.
|
|
}
|
|
init = false
|
|
|
|
...
|
|
```
|
|
|
|
This can be helpful because else the bar would display `"?"` before
|
|
the user changes his workspace for the first time.
|
|
|
|
|

|
|
|
|
When you've gathered all information you can update the block values
|
|
using for example `block.bg = value` and running
|
|
`bar.redraw <- block`.
|
|
|
|
|
|
## TODO
|
|
|
|
* Create some kind of easy to use init function for blocks (instead of
|
|
the `if !init` stuff I use at the moment).
|
|
* Add popups.
|
|
* Drop support for `ttf` fonts and use `pcf` fonts instead if
|
|
possible.
|
|
* or maybe some kind of different format altogether that's easily
|
|
hackable, such as suckless farbfeld?
