v0.0.11 — quicksilver

What's new

• Performance sweep. Across-the-board speedups for loading and comparing large GDX files:
  • Tauri commands now run asynchronously so the UI stays responsive during big reads.
  • Raw-mode FFI path for reading symbol data.
  • Arc<str> interning for repeated set-element labels (lower memory, faster compares).
  • Skip-table and HashSet-based filters for faster symbol/element filtering.
  • DataTable row cap to keep the grid snappy on very large symbols.

See BENCH_BASELINE.md for before/after benchmark numbers.

Install

• Debian/Ubuntu: gdxcomp_0.0.11_amd64.deb
• Fedora/RHEL: gdxcomp-0.0.11-1.x86_64.rpm

v0.0.10 — hotreload

What's new

• Reload all (↻) button in the Files toolbar, next to open-folder. Re-reads every loaded GDX file from disk and refreshes the symbol list. Useful when a GAMS run updates a GDX in place. Button is dimmed/disabled when no files are loaded.

axisfix

[0.0.9] — 2026-05-28

Fixed

• Chart x-axis (and y-axis on the second toggle) could render against a
  stale Plotly axis-range cache after switching units — the axis would
  drop to -1..6 instead of the actual year range. The <Plot>
  element now uses a React key derived from (symbol, unit, conversionFactor), forcing a full remount on unit change so Plotly
  reinitializes cleanly. Both axes also pin autorange: true.

birding

[0.0.8] — 2026-05-28

Added

• Unit conversion GtC ↔ GtCO2e (×44/12) for carbon mass — applies whenever
  the unit contains GtC (word-boundary regex; GtCe/GtCO2/GtCH4 are
  unaffected).
• Unit conversion GTonC ↔ GtCO2e (×44/12) for the verbose form
  (case-insensitive).
• Unit conversion GtCe ↔ GtCO2e (×44/12) — always applicable when the
  unit contains GtCe, independent of any e-dimension filter.
• Multiple unit conversions may now stack as toolbar buttons. Example:
  with e=co2* filter + GtCe/yr, the toolbar shows
  GtCe/yr | GtCO2e/yr | Gt/yr (each carries its own factor).
• WITCH mode now auto-snaps the x-axis to the t (year) dimension when
  WITCH is activated or auto-detected, if the current symbol has a t
  domain. Matches the behaviour already in selectSymbol for symbol
  changes.
• About dialog now shows the release codename and date inline with the
  version: gdxcomp 0.0.8 (birding — 2026-05-28).

Fixed

• @testing-library/dom is now an explicit dev dependency, fixing the
  Intel-Mac npm run tauri build failure reported in #1 (TS2305 on the
  screen re-export from RTL v16).

[0.0.7] — 2026-05-28

Performance sweep

Measured improvements (see BENCH_BASELINE.md for full numbers). All
changes are bench-justified; deferred items are documented inline.

Backend (Rust)

• Tuned [profile.release] (lto=fat, codegen-units=1, opt-level=3,
  strip=symbols) for both workspaces; [profile.bench] inherits release.
• LoadedFile::distinct_keys switched to HashSet<&str> + Vec (O(N²) → O(N)
  in the inner loop).
• O(1) symbol lookup: name_index: HashMap<String, usize> on LoadedFile
  and GdxFile. ipc_common_symbols_19files: 287 ms → 25 ms (11×).
• Bounded LRU record cache (crates/gdxcomp-core/src/cache.rs,
  Mutex<LruCache<String, Arc<Vec<Rec>>>>) shared via Arc<RecordCache>
  across LoadedFile clones. Capacity from GDXCOMP_RECORD_CACHE_SIZE
  (default 32). build_view_aggregated_4files: 10.58 ms → 574 µs (18×).
• build_view, distinct_keys, YearMapper::new, read_param_map now
  iterate Arc<Vec<Rec>> directly — no per-call deep clone.
• New build_chart / build_table + commands get_chart_view /
  get_table_view. Chart-tab IPC payload −31% (3.77 ms vs 5.48 ms).

Frontend

• Switched plotly.js-dist-min → plotly.js-basic-dist-min. Bundle 4.86 MB
  → 1.30 MB (−73%).
• Vite manualChunks + React.lazy(ChartView) + Suspense. Main-entry JS
  4.86 MB → 159 kB (30×) for first paint; Plotly fetched in parallel
  when the chart tab activates.
• Lazy table fetch on tab switch (was: every setup change sent the full
  table). Cached client-side; invalidated on setup change.
• Skip chart refetch on mode-only toggle when the current symbol has no
  t dimension.
• Client-side distinctKeys cache by (symbol, dim), invalidated when
  the loaded-file set changes.
• Stable DataTable row keys so sort/filter doesn't churn React fibers.

Tooling

• Added BENCH_BASELINE.md with criterion median wall-clock for every
  bench; rows appended per phase, never overwritten.
• New crates/gdxcomp-core/benches/ipc_loopback.rs mirrors the Tauri
  command bodies (including serde_json::to_string).
• Extended load_and_view.rs with multi-file and pathological cases
  (4 / 19 files, largest-symbol, distinct-keys 19-files, aggregated builds).
• scripts/bundle-size.sh captures the frontend baseline.

[0.0.6] — 2026-05-28

Added

• About dialog (click "gdxcomp" in the header): shows version, author, and
  pixel art witch hat easter egg.

turbo2000

[0.0.5] — 2026-05-27

Added

• Unit conversion T$/GtonCe → $/tCO2 (factor 1000×12/44) for carbon price
  symbols; toggle appears when unit matches T$/GtonC* pattern.
• "Remove all files" button in the file modal.
• Energy unit conversion TWh ↔ EJ available in all non-GDX modes.
• Y-axis title shows extracted unit […] in all modes.

Fixed

• Carbon price conversion regex enforces T$ before GtonC to avoid false
  match on inverted ratios.
• Unit conversion toggles restricted to non-GDX modes.

simca2000

[0.0.4] — 2026-05-27

Added

• WITCH mode: CH4 unit conversion GtCe/yr → Mt/yr using GWP from emi_gwp
  parameter (AR4 default = 25 if parameter absent).
• WITCH mode: N2O unit conversion GtCe/yr → Mt/yr using GWP from emi_gwp
  parameter (AR4 default = 298 if parameter absent).
• Energy unit conversion toggle TWh ↔ EJ for any symbol whose unit contains
  TWh (factor 3.6/1000); available in all modes.
• New backend command read_param_map to read any 1-dim parameter as a
  key→value map.
• Y-axis title shows the symbol unit in all modes (extracted from […] in
  description).

Fixed

• CH4 conversion now correctly applies the C→CO2 factor (44/12) before
  dividing by GWP.
