v1.9.0

[1.9.0] - 2026-04-21

Volume and edge groups now appear in the viewer alongside face and node groups, a new "Groups" settings tab exposes per-kind display tweaks, the bundled vtk.js is replaced by the tree-shaken npm package, and an optional animated background adds a cosmetic touch.

Added

• Volume groups — med2obj.py now computes the skin of every volume group in a 3D .med mesh and writes it into the .obj as a dedicated group. The viewer renders them as their own category with a filled isometric cube icon, toggle-able independently from face groups.
• Edge groups — level -2 groups (1D named cells) are extracted too and rendered as lines via a new EdgeActorCreator. Line width and depth offset (to avoid z-fighting with the skin) are user-controllable.
• Groups settings tab — new tab in the viewer Settings popup covering:
  • Edge-group thickness slider (1–10 px)
  • Edge-group depth-offset toggle
  • Node-group point-size multiplier (0.25×–4×)
  • Sidebar sort order (natural / by cell count)
  • Bucket groups by kind (on by default; off merges all four kinds into a single list sorted by the same order)
• Group-kinds legend in the help popup's Groups tab, showing each icon with a short description.
• Edge threshold multiplier is now persisted across sessions via vs-code-aster.viewer.edgeThresholdMultiplier (was previously editable but lost on reopen).
• Dream background — optional cosmetic viewer setting (vs-code-aster.viewer.dreamBackground) that drifts four EDF orange/blue blobs behind the mesh via a WebGL fragment shader. Theme-aware: blob intensity adapts to light vs dark themes, peak intensity is capped so overlapping blobs never fully replace the theme color. Does not affect mesh lighting.

Changed

• vtk.js migrated to @kitware/vtk.js npm package — the 2.6 MB bundled script is gone, replaced by tree-shaken ES-module imports and real TypeScript types. Opens the door to regular version upgrades.
• Settings popup: the "Edges" tab is renamed to "Mesh edges" and its copy rewritten to distinguish the wireframe edges drawn on each cell from the new edge groups. Tab content now scrolls when it overflows instead of clipping.
• Sidebar groups now bucket volumes, faces, edges, and nodes in that order, each with its own icon.

Fixed

• Mesh edge colors now repaint immediately on theme switch instead of waiting for the next camera move.
• Translucent meshes (highlighted parent behind a selected sub-group) no longer wash out on light themes — vtk.js 35's Order-Independent Transparency pass is bypassed in favor of plain SRC_ALPHA blending.
• .obj files cached under .vs-code-aster/mesh_cache/ from older extension versions are invalidated when the converter changes (via the bumped med2obj-version: 2 header).
• Screenshots now work again after the vtk.js migration — the capture path switched to vtk.js's captureNextImage API (which doesn't depend on preserveDrawingBuffer), and the dream background is composited behind the mesh when enabled. The screenshot button's hover highlight is also stripped from the full-viewer capture so it no longer bakes into the saved image.

v1.8.1

[1.8.1] - 2026-04-20

Follow-up polish on the .export editor form: smarter autocomplete suggestions and the saved file now opens automatically after create/save.

Added

• Type-aware autocomplete — file name suggestions in the export form are now filtered by the selected F-line type so irrelevant files are hidden:
  • mmed / rmed rows accept .med, .mmed, .rmed, and any custom extension registered in vs-code-aster.medFileExtensions (so user-added MED extensions like .71 show up).
  • comm rows accept .com* (covers .comm, .com0, .com1, ...).
  • mess, msh, and dat rows require a literal extension match.
  • Types without a conventional extension (mail, base, libr, tab, nom) still accept any file.
• Autocomplete on output rows — output file name fields now use the same autocomplete dropdown as inputs, making it easy to reuse existing file names for outputs.
• Reveal on save — creating or saving an .export file from the form now opens the file in a text editor (or focuses the existing tab if it's already open), so you immediately see the formatted result. Stale tabs left over from a rename are closed automatically.

Fixed

• The hidden .vs-code-aster/ folder no longer appears in the export form's autocomplete suggestions.

v1.8.0

[1.8.0] - 2026-04-20

Full rewrite of the .export form in Svelte + Tailwind, first-class language support for .export files (syntax highlighting, formatter, format-on-save), and a batch of UX upgrades.

Added

• Redesigned export form — rewritten in Svelte 5 + Tailwind 4, styled with VS Code theme tokens (--vscode-input-*, --vscode-focusBorder, --vscode-editorWarning-foreground, ...), so it looks native in every theme.
  • Tab icon is a blue pencil; tab title lives-updates to match the filename (falls back to untitled).
  • Titles inside the form adapt to mode: "Create a new export file" vs "Edit an export file".
  • New export files are pre-seeded with a sensible default: comm + mmed inputs and an rmed output, filenames simvia.comm / simvia.mmed / simvia.rmed.
  • .export extension locked as a visual suffix on the filename field — it can't be edited away.
  • Nested paths supported in the filename (subdir/file.export); missing folders are created on save.
  • Unsaved drafts persist via vscode.setState + retainContextWhenHidden, so switching tabs or reloading the panel no longer clears the form.
• File rows — drag-to-reorder (powered by svelte-dnd-action, theme-colored drop zones, keyboard-accessible); per-row × delete; full-width "Add input/output file" button at the end of each section.
  • Type dropdown is filtered by direction (inputs vs outputs) and shows a Type placeholder on new rows; the file-type list is the full code_aster set (comm, mmed, rmed, mess, nom, base, mail, libr, tab, msh, dat).
  • Unit auto-increment scoped to the same type and max+1 (so med: 20, 50 → next is 51, not 21), idempotent when re-picking the same type; nom rows are locked to unit 0; ArrowUp/Down steps integer inputs.
  • Name autocomplete list matches the type dropdown styling; empty rows (no type and no name) are ignored by validation and on save.
• Validation — per-field inline error messages, a sticky footer with clickable error / warning counts that smooth-scroll to the corresponding panel.
  • Blocking errors: filename required, parameters must be integers, at least one comm input file required.
  • Non-blocking warnings: duplicate unit across files (listing the file names), no mesh file set, no rmed output set, rename-in-edit-mode (tells the user the original file will be deleted).
• .export language support — new TextMate grammar (source.export) colors P/F directives, parameter names, file types, direction flags (D vs R/RC), unit numbers, and # comments.
• Document formatter for .export — available via Format Document. On save/create the form applies the same formatter automatically:
  • Groups lines into # Simulation parameters, # Input files, # Output files sections separated by blank lines.
  • Sorts F lines within each direction by a canonical type priority (comm, mmed, rmed, mess, nom, base, mail, libr, tab, msh, dat).
  • Keeps standalone # comments attached to the line they precede.
  • Emits a three-line header at the top crediting VS Code Aster and Simvia; re-saving is idempotent (no stacked headers).
• Dedicated pencil icon (media/images/icone-edit.svg) for the "Edit export file" command, replacing the plain $(book) codicon.
• Extension now activates on onLanguage:export, so opening a .export file registers the formatter without any prior command run.
• Refreshed Simvia logo (new SVG), separate light/dark variants for both Simvia and code_aster logos in the form header.

Changed

• Editing a file and changing its name now renames the file on disk (old file is deleted after the new one is written). A warning panel previews the rename before the user saves.
• When writing a file, the output is always formatted (P/F grouping, section headers, shoutout) — so files stay clean across multiple save cycles.

Fixed

• Loading an existing .export into the form (e.g. after a tab switch) no longer clobbers the pre-filled data with the seeded default.
• Removing the last row no longer leaves stale autocomplete suggestions keyed to the dead row.
• Missing parent directories no longer cause save to fail silently when the filename contains a path separator.

Removed

• The legacy vanilla HTML/CSS/JS export form (webviews/export/export.{html,css,js}) and its hardcoded blue-on-light styling.
• Unused media assets: media/images/aster.png, media/icons/3d.svg, media/icons/3d_light.svg.

v1.7.1

[1.7.1] - 2026-04-17

Centralize extension-generated files under a single .vs-code-aster/ folder per project, with timestamped run logs and automatic migration from legacy locations.

Added

• Project-local .vs-code-aster/ folder grouping all extension-generated files:
  • mesh_cache/ — converted .obj files (previously .visu_data/)
  • screenshots/ — PNGs saved from the viewer's screenshot button (previously next to source files)
  • run_logs/ — one timestamped log per code_aster run (previously a single overwritten .vscode-aster-run.log)
• New vs-code-aster.maxRunLogs setting (default 10) to cap run-log retention; oldest logs are pruned when a new run starts
• med2obj-version header in generated .obj files: the extension now detects stale caches from older converter versions and regenerates them automatically
• Automatic migration of legacy .visu_data/ and .vscode-aster-run.log on first use, with info notifications so users know where files moved

v1.7.0

[1.7.0] - 2026-04-16

New viewer toolbar with bounding box, wireframe, and screenshot tools.

Added

• Top toolbar in the mesh viewer with three new tools:
  • Bounding box: toggleable wireframe cube with colored axes (X red, Y green, Z blue), corner dots, a "0" origin marker, and dimension labels anchored in 3D
  • Wireframe mode: toggle between solid surface and wireframe rendering to inspect mesh density
  • Screenshot: left click saves the 3D view as PNG next to the source file and copies to clipboard; right click captures the full viewer including the sidebar
• Toolbar button tooltips using the same inline hover pattern as the rest of the UI
• Toolbar tab in the viewer help popup documenting the three new tools
• Updated README with diagnostics, terminal reuse, direct .med opening, and toolbar features

Fixed

• Popup z-order: help and settings popups no longer render behind the sidebar
• Sidebar tooltip z-order: filter/clear tooltips no longer hidden behind the top toolbar

• Feat/visualize bounding boxes by @ulysse-bouchet-simvia in #23

Full Changelog: v1.6.1...v1.7.0

v1.6.1

[1.6.1] - 2026-04-15

Standalone mesh visualization: click any .med file to open the viewer directly, even without a .comm/.export pair.

Added

• Click a .med / .mmed / .rmed file in the explorer to open it straight in the mesh viewer, via a custom editor registered with priority: "default" that bypasses the "file is binary" warning
• Automatic MED detection: when a tab opens a file whose first bytes match the HDF5 signature, a notification offers to register the extension (e.g. .71) and open it in the viewer in one click
• "Open as MED mesh" action exposed as an editor-title button (on auto-detected MED files) and as a right-click entry in the explorer
• Tabs for files whose extensions are in vs-code-aster.medFileExtensions are auto-rerouted to the mesh viewer, no window reload required after registering a new extension
• The mesh viewer tab now carries the shared orange cube icon (same as .med files in the file tree)
• Inline error state in the viewer: when .med→.obj conversion fails (e.g. medcoupling not installed), the reason is shown in the tab instead of an indefinite loading screen

v1.6.0

[1.6.0] - 2026-04-15

Run workflow overhaul: terminal reuse, automatic diagnostics in the Problems panel, and refreshed toolbar icons.

Added

• Run diagnostics: <A> warnings and <E>/<F> errors from code_aster, Python tracebacks, SyntaxErrors, fatal errors (e.g. segfaults), and MED/Fortran errors now surface automatically in the VS Code Problems panel — no F mess entry required in the .export
• Diagnostics attached to the originating .comm/.com1 line when possible (via CMDTAG markers and Python tracebacks), and cleared between runs
• The existing code-aster runner terminal is now reused across runs instead of spawning a new one each time
• Colored toolbar icons: blue rocket for the run button (shared with the .export file icon) and orange eye for the mesh viewer button (matches the .med palette)

What's Changed

• Feat/improve run workflow by @ulysse-bouchet-simvia in #20
