Eager layer activation seems to be more desirable for non time-based
overloading. In addition to facilitating modifier clicking for non-managed
mice, it appears some applications (E.g i3) care about isolated modifier down
events.
Some applications make use of the alt (e.g firefox) and meta (e.g gnome)
keys in isolation. Thus it is necessary to interpose additional events
to prevent the likes of '<alt down> <alt up>' from being interpreted as
key presses.
E.G
[alt]
a = x
will currently cause 'alt+a' to produce:
<alt down>
<alt up>
<x down>
<x up>
In most cases this is identical to '<x>', however in some contexts the
additional alt keypress is meaningful.
To prevent this, we intelligently emit '<alt>+<control>' instead by sandwiching the
'<alt up>' event like so: '<control down> <alt up> <control up>'
The full sequence thus becomes:
<alt down>
<control down>
<alt up>
<control up>
<x down>
<x up>
keyd redux take 1.
A rewrite which simplifies the config format and provides a
solid foundation for incrementally introducing experimental
features.
Internally:
- Modularized and rewrote most of the code
- Added a mini testing framework (t/)
Externally:
- Eliminated layer inheritance in favour of simple types.
(layouts are now defined with `:layout` instead of `:main`)
- Macros are now repeatable.
- Overload now accepts a hold threshold timeout.
- Config files are now vendor/product id oriented.
- SIGUSR1 now triggers a config reload.
- Modifiers are layers by default and can be extended directly.
- Config files now end in `.conf`.
- `layert()` is now `toggle()`.
- All layers are 'modifier layers' (terminological change)
- Eliminated the dedicated modifer layout.
- Modifiers no longer apply to key sequences defined within a layer.
(Layer sequences are now always executed verbatim.)
The old behaviour was unintuitive and can be emulated using nested
layers if necessary.
