feat: add configurable keybindings via keybindings.json - #3480

WalkthroughThe change adds Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new configurable keybindings behavior can mishandle valid array-based configuration files in the editor, while malformed bindings or unreadable user files may cause key actions to fail, throw, or silently revert to defaults.

Missing null guard on the block component model in three handlers. getBlockComponentModel(getFocusedBlockInStaticTab()) returns undefined when no block node holds focus. Each site then dereferences bcm.viewModel or bcm.openSwitchConnection and throws inside a key handler.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Unvalidated commandStr parsing in two numeric command handlers. Both handlers pass parseInt(commandStr) straight into a lookup. kb.commandstr is optional in user configuration, so NaN reaches the callee and produces an out-of-range action instead of a rejected binding.

The Wave Config UI still assumes every configuration file holds a JSON object. keybindings.json holds an array, and the array case is handled with one path comparison in the save validation while the load path and the error text keep the object assumption. Add a declarative field on ConfigFile, for example isArray?: boolean, and read it in both places.

Report read errors other than "file not found".
readKeybindingsFile returns no bindings and no error for every read failure. A permission error or an I/O error on the user file then silently reverts all keybindings to defaults, and no ConfigError reaches the UI. The rest of this file distinguishes the two cases in readConfigHelper with os.IsNotExist(readErr).
🛠️ Proposed fix
func readKeybindingsFile(fsys fs.FS, fileName string) ([]KeybindingConfigType, []ConfigError) {
barr, err := fs.ReadFile(fsys, fileName)
if err != nil {
barr, err = fs.ReadFile(fsys, filepath.ToSlash(fileName))
}
if err != nil {
- return nil, nil
+ if errors.Is(err, fs.ErrNotExist) {
+ return nil, nil
+ }
+ return nil, []ConfigError{{File: fileName, Err: err.Error()}}
}This needs errors in the import list.

Replace hardcoded keyboard shortcuts in keymodel.ts with a data-driven system. Default bindings are defined in defaultconfig/keybindings.json and users can override them in ~/.config/waveterm/keybindings.json. The merge logic preserves defaults while letting users remap or disable individual commands. A "Keybindings" section is added to the Wave Config UI for in-app editing. Changes are picked up automatically via the file watcher.

Global keybindings are no longer hard-coded in
keymodel.ts. Defaults live inpkg/wconfig/defaultconfig/keybindings.jsonand users can override them in~/.config/waveterm/keybindings.json:keysarrayMerging is done on the Go side and delivered to the frontend via wshrpc; changes
are picked up through the existing config event system.
Testing
pkg/wconfig/keybindings_test.go: 10 unit tests covering merge logic(override, add, disable, no mutation of defaults) and user file parsing
(valid/invalid/missing JSON) - all passing.
