# Cozy and Windy
|
|
||||||
|
|
||||||
Editor theme ported from the Rider scheme of the same name.
|
|
||||||
|
|
||||||
It colors the editor surface, C/C++ syntax, and tape-atom DSL keywords
|
|
||||||
emitted by `local.tape-atom-syntax`. It does not change workbench chrome.
|
|
||||||
|
|
||||||
## Install
|
|
||||||
|
|
||||||
```powershell
|
|
||||||
cd C:\projects\Pikuma\ps1\.vscode\cozy-and-windy
|
|
||||||
npm run package
|
|
||||||
code --install-extension .\cozy-and-windy-0.1.0.vsix --force
|
|
||||||
```
|
|
||||||
|
|
||||||
Reload the window. Select **Cozy and Windy** as the color theme, or set
|
|
||||||
`workbench.colorTheme` to `Cozy and Windy` in the PS1 workspace settings.
|
|
||||||
|
|
||||||
Keep `local.tape-atom-syntax` installed. This theme colors those token
|
|
||||||
types; it does not classify them.
|
|
||||||
|
|
||||||
## Inspect
|
|
||||||
|
|
||||||
Open `hello_camera.atom.c` and run **Developer: Inspect Editor Tokens and Scopes**
|
|
||||||
on `MipsAtom_`, an atom name, `atom_info`, `R_PrimCursor`, a `gte_*` call,
|
|
||||||
and a `mac_*` call.
|

* ─── Per-entry semantics (decoded from libgte msc02 VectorNormal) ───
|
|
||||||
* Each entry is `1/sqrt(x)` in 1.12 fixed point (value / 4096).
|
|
||||||
* The 192 entries span 4 octaves of the input magnitude, with 48 entries per octave:
|
|
||||||
* Octave 0 (entries 0- 47): mantissa in [0x8000, 0x10000) output ~[1.000, 0.707]
|
|
||||||
* Octave 1 (entries 48- 95): mantissa in [0x10000, 0x20000) output ~[0.707, 0.500]
|
|
||||||
* Octave 2 (entries 96-143): mantissa in [0x20000, 0x40000) output ~[0.500, 0.354]
|
|
||||||
* Octave 3 (entries144-191): mantissa in [0x40000, 0x80000) output ~[0.354, 0.251]
|
|
||||||
* Within each octave, 8 sub-entries interpolate over the 8 fractional bits of the mantissa
|
|
||||||
* (the byte `(0x80 | (i mod 8))` for the lower-byte of the aligned value).
|
|
||||||
* Sampling the first value of each octave:
|
|
||||||
* [0] 0x1000 = 1.0000 ; 1 / sqrt(1.0000)
|
|
||||||
* [48] 0x0e4f = 0.8940 ; 1 / sqrt(1.2500)
|
|
||||||
* [96] 0x0d10 = 0.8164 ; 1 / sqrt(1.5000)
|
|
||||||
* [144] 0x0c0a = 0.7520 ; 1 / sqrt(1.7500)
|
|
||||||
* And representative sub-entries within octave 0 (mantissa in [0x8000, 0x8100)):
|
|
||||||
* [0] 0x1000 = 1.0000 ; 1 / sqrt(0x8000)
|
|
||||||
* [1] 0x0fe0 = 0.9922 ; 1 / sqrt(0x8100)
|
|
||||||
* [2] 0x0fc1 = 0.9846 ; 1 / sqrt(0x8200)
|
|
||||||
* [3] 0x0fa3 = 0.9773 ; 1 / sqrt(0x8300)
|
|
||||||
* [4] 0x0f85 = 0.9700 ; 1 / sqrt(0x8400)
|
|
||||||
* [5] 0x0f68 = 0.9629 ; 1 / sqrt(0x8500)
|
|
||||||
* [6] 0x0f4c = 0.9561 ; 1 / sqrt(0x8600)
|
|
||||||
* [7] 0x0f30 = 0.9492 ; 1 / sqrt(0x8700)
|
|
||||||
*
|
|
||||||
* The algorithm's `addi -64 / sll 1 / lh` selects the entry at `(aligned - 64) * 2` for the case where `aligned` has its top bit at bit 24.
|
|
||||||
* After the sllv/srav pair, `aligned` always lands in `[0x80, 0x100)`
|
|
||||||
* (with top bit at bit 24 → after `sub $aligned - 64`, the index sits in `[0x40, 0x80) * 2 = [0x80, 0x100)` bytes = entries [64, 128) within the sqrtbl).
|
|
||||||
* The earlier 64 entries (octave 0) are reached when the magnitude after shifting puts the top bit below bit 24 (the `sllv` branch),
|
|
||||||
* and the load upper_halves of the table bracket the input range.
|
|
||||||
* The later 64 entries (octaves 2-3) are the `srav` branch when the magnitude's top bit is well above bit 24.
|
|
||||||
*
|
|
||||||
* Reproduced verbatim from libgte (verified against libpsn00b/psxgte/vector.s:100-123 — 24 rows × 8 halfwords, last entry 0x0804).

|
* Reads pad[0].buttons + pad[0].left_x;
|
||||||
|
* Applies the input-semantics deltas to cube_rot.y + floor_rot.y:
|
||||||
|
* - D-pad Left: cube_rot.y += 30, floor_rot.y += 5
|
||||||
|
* - D-pad Right: cube_rot.y -= 30, floor_rot.y -= 5
|
||||||
|
* - Analog stick X (dead zone 0x70..0x90):
|
||||||
|
* cube delta = (0x80 - left_x) >> 2 (range approx -32..+32)
|
||||||
|
* floor delta = (0x80 - left_x) >> 5 (range approx -4..+4)
|
||||||
|
* - D-pad + analog deltas add when used together.
|
||||||
|
*
|
||||||
|
* Convention:
|
||||||
|
* pad_state = 0 means no buttons active.
|
||||||
|
* The fail-safe zero-button value flows through unchanged, so a disconnected/fresh pad produces no rotation.
|
||||||
|
* The branch_le_zero pattern below matches the existing pad_input_demo convention (atom body lines 248/257).
|
||||||
|
*
|
||||||
|
* Signed-delta trick:
|
||||||
|
* load_byte_u zero-extends left_x to 32 bits; sub_u from 0x80 wraps to a SIGNED two's-complement value in the negative range;
|
||||||
|
* shift_aright (sra) then correctly sign-extends the shift for both positive (left_x < 0x80) and negative (left_x > 0x80) cases.
|
||||||
|
* Digital pads publish left_x = 0x80 → delta = 0 → no rotation, so the analog step is naturally a no-op for digital controllers.

|

-- The projection is built from the root atom body only; invocation ancestry recursively expands nested components.
|
|
||||||
-- The items stream is the single ordered source of truth; `word_events` and `markers` are dense views over it.
|
|
||||||
--
|
|
||||||
-- The helper below operates on a body string (not a body_entry) so the pass can call it without depending on the older SourceScan / body_off conventions.

--- @class InvocationRecord
|
|

--- Lives at `atom.paths.invocations[*]`. Constructed once at the single invocation-construction site
|

--- (`emit_invoke_begin` inside `_project_emission_inner`); `invoke_begin` / `invoke_end` markers in the items stream share the same `id`.
|

--- @field id integer -- 1-based, monotonic per-atom invocation id (0 is reserved for "no open invocation")
|
|
||||||
--- @field parent_id integer -- 0 for the outermost (root) call; otherwise the id of the immediately enclosing invocation
|
|
||||||
--- @field kind string -- "comp_bare" | "comp_proc" (component form that triggered the expansion)
|
|
||||||
--- @field component_name string -- Bare component name without the `mac_` prefix
|
|
||||||
--- @field call_text string -- Immediate `mac_X(...)` token text (or root call text for the outermost entry)
|
|
||||||
--- @field root_call_text string -- IMMUTABLE outermost `mac_X(...)` token text for every word emitted in this call's expansion
|
|
||||||
--- @field call_path string -- Source path of the call site (root atom source for direct calls, component source for nested expansions)
|
|
||||||
--- @field call_line integer -- Source line of the call site
|
|
||||||
--- @field def_path string -- Source path of the component definition
|
|
||||||
--- @field def_line integer -- Source line of the component declaration
|
|
||||||
--- @field start_pos integer -- 0-based emitted-word position of the FIRST word inside this invocation (the value of `word_idx` AT `emit_invoke_begin` time, BEFORE the first word is emitted). Words emitted inside this invocation occupy `start_pos..start_pos+#body_lines-1` (inclusive, 0-based). Downstream DWARF/provenance consumers MUST read this; do NOT reconstruct it from `start_word` (which is the 1-based items index including `invoke_begin`/`invoke_end` markers).
|
|
||||||
--- @field end_pos integer -- 0-based position of the LAST word inside this invocation (set by `emit_invoke_end` to `word_idx - 1` AFTER all body words are emitted).
|
|
||||||
--- @field start_word integer -- 1-based items index of the `invoke_begin` item
|
|
||||||
--- @field end_word integer -- 1-based items index of the `invoke_end` item (set by `emit_invoke_end`)
|
|
||||||
--- @field word_count integer -- Number of `word` items emitted between `start_word` and `end_word` (inclusive)
|
|
||||||
--- @field debug_skip boolean -- `debug_skip` stamp; true iff `corpus.components[name].debug_skip` is true at construction. Always boolean (never `nil`).
|
|
||||||
--- @field errors table[] -- Per-invocation construction errors (cycle / count_mismatch); does not include pass-level errors
|
|
||||||
|
|
||||||
-- Internal recursive walker. The items stream holds every emitted event in order; `word_events`, `markers`,
|
|
||||||
-- `invocations`, `errors`, `warnings` are dense views / side outputs appended alongside.
|

||||||
--
|
|
||||||
-- Output rules:
|
|
||||||
-- * `word` items record: `invocation_ids` (innermost last) and `outermost_invocation_id` (0 if no invocation is open).
|
|
||||||
-- * `invoke_begin` / `invoke_end` items are zero-width at the current word index; the same `word_index` is recorded on both.
|
|
||||||
-- * `root_call_text` is the outermost `mac_X(...)` token text for every word emitted inside a component expansion;
|
|
||||||
-- it is `nil` for direct words emitted from the root atom body.
|
|
||||||
-- * `call_text` is the IMMEDIATE top-level token spelling for the word (for nested words this is the inner `mac_X(...)` token;
|
|
||||||
-- for direct words it is the trimmed encoder token).
|
|
||||||
-- * `def_path` / `def_line` are the definition site of the current body (component source for nested words; root atom source for direct words, filled in by the pass caller).
|
|
||||||
-- * Unknown uncounted macros emit one opaque word + one warning. Unknown metadata-backed macros (entry in `word_counts`) emit the declared word count, no warning.
|
|
||||||
-- * Cycle detection uses an active DFS stack (`visiting`); a cycle appends a construction error to BOTH the projection errors and the cycle invocation's own errors,
|
|
||||||
-- then breaks out without recursing (the cycle entry still receives an invocation ID + paired `invoke_begin` / `invoke_end` items, so the boundary invariant is preserved).
|
|
||||||
-- * Component declared-count mismatch (declared vs. measured) is a construction error (kind = "count_mismatch"); recorded on the invocation record and pass-level errors list.
|
|
||||||
-- * Final boundary check: if any invocation is still open at end of walk, surface a "unbalanced" construction error.

See `token_skips_leading_comma` for the contract.
