The Model was getting unmaintanable mess. This is an attempt to refactor/rewrite the Model so that data of certain type is exposed in standardized way, offering certain standard manipulations for that data type, and on the GUI side, certain standard widgets to tied to that data.
This rewrite closes#72, #106 and #120.
The modelData is moving towards clear meaning: it's the part of the
GUI state that is undone and also recovered from disk. This changes
the recovery data so that the undo and redo stacks are not undone,
but that is unlikely a good idea anyway, as it grows the recovery
data into unreasonable sizes.
This has also the nice benefit of undoing the cursor position, which
closes#64.
The yaml marshaling and umarshaling seems to allocate a lot of memory. When saving the recovery file, the memory use jumped up by hundreds of megabytes. Switch to using json marshaling for the recovery file, as it does waste memory so badly. Binary marshaling was also an option, but its nice in emergency situations that the user can glance the recovery file and perhaps, with some effort, recover stuff from it. Json is good enough for manual recovery during emergency situations.
The options are stereo, left and right. Similar to oscillator sample settings, if you tamper with these, it starts to show "custom". Used some of the generic features of go1.18, so had to update go.mod to require go1.18.
The RPC and sync library mechanisms were removed for now; they never really worked and contained several obvious bugs. Need to consider if syncs are useful at all during the compose time, or just used during intro.
The keyboard shortcuts were too wonky, so removed them altogether. Had to remove also unit wrapping from model (now it just clamps the parameter to the current units) as it did not play nice with the new editor.
Closes#70.
Creating such patterns is unnecessary and was a relic of the past. We can leave the order completely uninitialized and let the user fill it as needed.
Related to #54.
send targets are now by ID and Song has "Score" part, which is the notes for it. also, moved the model part separate of the actual gioui dependend stuff.
sorry to my future self about the code bomb; ended up too far and did not find an easy way to rewrite the history to make the steps smaller, so in the end, just squashed everything.
