editor_init.rs

1//! Editor construction and initialization.
2//!
3//! `Editor::new` and friends — the entry points that take a configuration,
4//! terminal dimensions, color capability, and filesystem implementation
5//! and return a ready-to-use Editor with every field initialized.
6//!
7//! Also includes `start_background_grammar_build`, which kicks off the
8//! initial grammar registry build asynchronously so startup doesn't block.
9
10// Re-use everything mod.rs imports — the constructors touch every field
11// on Editor and most of the types in the module.

90/// Pre-built non-trivial inputs handed to [`Editor::from_parts`].

92/// Everything in here either depends on external resources (filesystem,
93/// config, plugins, themes, terminal dimensions, …) or is one of the
94/// few editor-global fields a caller wants to control directly — most
95/// notably the initial set of `windows`. Trivial fields (counters at
96/// zero, empty collections, `None` options, registries built from
97/// scratch with no dependencies) are filled in by the constructor.
98///
99/// The factory methods (`Editor::new`, `Editor::with_working_dir`,
100/// `Editor::with_working_dir_opts`, `Editor::for_test`,
101/// `Editor::with_options`) build a value of this type and pass it to
102/// `Editor::from_parts`. No production code constructs `Editor`
103/// without going through `from_parts`, so adding a field here forces
104/// every factory to provide it.

1893/// Walk every typed `Action` and the contexts most relevant to UI
1894/// labels (`Normal`, `Prompt`, `Popup`, `FileExplorer`,
1895/// `CompositeBuffer`, `Settings`, `Terminal`), and populate the
1896/// snapshot's `keybinding_labels` map with `<action>\0<context>` →
1897/// formatted label (e.g. `"cycle_live_grep_provider\0prompt"` →
1898/// `"Alt+P"`). The plugin-side `editor.getKeybindingLabel(action,
1899/// mode)` API reads from this map, so plugins displaying hints in
1900/// their UIs (overlay headers, status messages) can look up the
1901/// user's *actual* binding rather than hardcoding a key string.
1902///
1903/// This runs once at startup. If the user later edits their keymap
1904/// without restarting fresh, the labels go stale. That's acceptable
1905/// for v1 — keymap edits today already require a restart for full
1906/// effect; a subsequent commit can wire snapshot refresh into the
1907/// keymap-reload path.
