Pick a small boundary. + Prefer leaf modules or modules with already-ported callers. Read the target + JavaScript file and every direct caller before writing MLscript. + +2. Port the implementation. + Add a `.mls` file next to the old `.js` file. Follow existing Web IDE + MLscript style: UCS conditionals, conjunctive `and` guards, direct declared + globals when possible, and shared helpers such as `common/JS.mls`. + +3. Keep browser APIs explicit. + If the port needs a browser or JavaScript global, add the smallest useful + declaration to `hkmc2/shared/src/test/mlscript/decls/Prelude.mls`. Use + `globalThis` only when MLscript/codegen cannot express the access, and leave + a short comment explaining why. + +4. Switch imports deliberately. + After package compilation generates the `.mjs`, update callers from the old + `.js` module to the generated `.mjs`.

Run package verification. + Run: + + ```sh + timeout 300s sbt "hkmc2PackagesTest/testOnly hkmc2.PackageTestRunner -- -z web-ide" + ``` + + Check `git status` afterward.

Run broader verification when needed. + Run `timeout 1500s sbt hkmc2AllTests/test` before committing if the change + touches shared compiler behavior, `Prelude.mls`, module resolution, codegen, + package vendoring, or golden-test-visible behavior. + +8. Commit only reviewed output. + Review `git diff`, run `git diff --check`, and keep any golden snapshot + rewrites only when they are intentional. Use a one-line commit message. + +## Style Notes + +- Do not write `else if`; use Ultimate Conditional Syntax. +- Prefer `if value is ~Absent and ...` over nested null checks. +- Do not recreate local `isAbsent` helpers; import the shared `Absent` pattern. +- Prefer direct declarations from `Prelude.mls` over `globalThis`. +- Do not remove existing `end` markers. +- Do not use `asInstanceOf` unless there is no reasonable typed alternative.

Check the diff. + Run: + + ```sh + git diff --check + git status --short + ``` + + No golden snapshots or unrelated test files should change. + +6. Run browser verification. + Prefer a headless browser so the user's desktop is not disturbed.

Execute reopens Output. + +Phase 6: + +- Compiled split view opens and closes. +- Target selector switches mock content. +- Copy and Download act on the currently selected mock output. +- Closing compiled view preserves editor tab, scrollability, and diagnostics. + +Phase 7: + +- Command palette opens from button and shortcut. +- Command search filters rows. +- Escape and close button close the dialog. +- Real commands dispatch real events;

charset=UTF-8 Content-Transfer-Encoding: 8bit - Add projects.renameProject and a Rename action with its own sub-dialog in the switcher. Renaming the current project re-dispatches current-project-changed so the toolbar pill updates immediately. - Lock the modal to a fixed height (min(560px, calc(100vh - 48px))) instead of max-height, so the dialog no longer jumps as projects are added or removed; the project list scrolls inside. - File count now includes std files: a small fs.getAllFiles predicate counts std nodes once and is added to the per-project persisted count. - Visual pass on the modal: - Delete action button takes a soft red palette to signal danger. - Rename confirm button shares the accent palette with Create. - Close (×) button becomes a 28×28 inline-flex box so the glyph is centered. - Project cards get user-select: none. - Restore the MLscript wordmark in the toolbar's leftmost slot: "ML" in Rubik 600 sans, "script" in Instrument Serif italic at the accent color. The brand sits in a new .toolbar-leading flex container next to the project pill. - index.html loads Instrument Serif from Google Fonts alongside Rubik and Google Sans Code. --- .../web-ide/components/ProjectSwitcher.mls | 93 ++++++++++++++++++- .../web-ide/components/ToolbarPanel.mls | 20 +++- .../web-ide/filesystem/projects.mls | 20 ++++ .../test/mlscript-packages/web-ide/index.html | 2 +- .../test/mlscript-packages/web-ide/style.css | 76 +++++++++++++-- 5 files changed, 195 insertions(+), 16 deletions(-) diff --git a/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls b/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls index 427fbc0b11..bb1f9528f0 100644 --- a/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls +++ b/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls @@ -1,3 +1,4 @@ +import "../filesystem/fs.mls" import "../filesystem/projects.mls" import "../common/JS.mls" import "../common/Logger.mls" @@ -39,10 +40,20 @@ fun relativeTime(stamp) = fun filesLabel(count) = count + " " + (if count === 1 then "file" else "files") +// Std files are shared across projects but show up in every project's tree, so +// the displayed count should include them. +fun stdFileCount() = + let files = fs.getAllFiles((path, node) => node.attrs.("std") is true) + Object.keys(files).length + +fun totalFileCount(projectId) = + projects.fileCount(projectId) + stdFileCount() + class ProjectSwitcher extends HTMLElement with let selectedId = "" pendingDelete = null + pendingRename = null creating = false createName = "" @@ -89,6 +100,19 @@ class ProjectSwitcher extends HTMLElement with

The switcher modal also gained a read-only file preview with a clickable file list. Storage layer: - filesystem/persistent.mls grows snapshotProject(id) (reads every file for a project out of localStorage as { path, payload } records) and writeProjectFile(id, path, payload) used by import to seed the new project's namespace without going through the in-memory tree. - filesystem/projects.mls adds adoptProject(meta) that allocates a fresh id while preserving the imported project's descriptive metadata (description, color, icon, createdAt, activeFile). Switcher UI: - Export button in the detail action row downloads .mls-project.json shaped as { schema: "mlscript-project/v1", exportedAt, project, files }. - Import opens a dedicated sub-dialog that explains the accepted format, shows the practical localStorage size limit, and surfaces parse errors inline. After a successful import the new project is selected in the list but not auto-opened. - A two-column preview pane replaces the old "coming soon" note. The left column lists every file the project ships with (user files merged with std lib files, sorted, depth-indented) and the right column renders that file's content as plain monospaced text. - Clicking a file routes through a setPreviewPath setter method so the cross-scope write reaches the private class field; preview content switches accordingly. - Modal sized to 1100x720 to give the preview real estate. The detail pane is a flex column so the preview grows to fill remaining vertical space. - Detail header carries only glyph + name + description; the four action buttons (Rename, Export, Delete, Open) sit on their own row so the project name no longer competes with them. - Stats grid is now a single row of four inline label/value pairs. --- .../web-ide/components/ProjectSwitcher.mls | 265 ++++++++++++++++-- .../web-ide/filesystem/persistent.mls | 35 +++ .../web-ide/filesystem/projects.mls | 18 ++ .../test/mlscript-packages/web-ide/style.css | 207 +++++++++++++- 4 files changed, 493 insertions(+), 32 deletions(-) diff --git a/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls b/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls index bb1f9528f0..dc3a035493 100644 --- a/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls +++ b/hkmc2/shared/src/test/mlscript-packages/web-ide/components/ProjectSwitcher.mls @@ -1,4 +1,5 @@ import "../filesystem/fs.mls" +import "../filesystem/persistent.mls" import "../filesystem/projects.mls" import "../common/JS.mls" import "../common/Logger.mls" @@ -56,6 +57,8 @@ class ProjectSwitcher extends HTMLElement with pendingRename = null creating = false createName = "" + previewPath = "" + importError = "" fun connectedCallback() = this.render() @@ -84,6 +87,10 @@ class ProjectSwitcher extends HTMLElement with New project + @@ -100,6 +107,30 @@ class ProjectSwitcher extends HTMLElement with

It updated Lowering.term_nonTail to use Assign(noSymbol, ...) for non-tail results, but missed Lowering.program (used by MLsCompiler when emitting .mjs files). The result was that every module's last top-level expression was wrapped in Return and JSBuilder dutifully emitted it as `return EXPR;` at module scope — illegal JS that broke every Web IDE component with `customElements.define(...)` as its last statement ("Uncaught SyntaxError: Illegal return statement" in the console). Fixing it in Lowering.program is tempting but breaks the diff-test worksheet path: JSBackendDiffMaker explicitly maps top-level Return into an Assign so it can display the result value. Both paths emit the same IR but want different JS for the trailing Return. So fix this in JSBuilder.programBody — the module-emission entry point. Apply Block.mapReturn there to rewrite Return(res) → Assign(noSymbol, res, End()) before handing the block to `block`. The worksheet path (jsb.worksheet) is untouched and keeps its existing semantics. The bundled sjs diff-test goldens have been updated mechanically: every `return EXPR` at the end of a module-mode sanitized JS dump becomes `EXPR;`, which is what would actually be emitted for a real module. --- .../scala/hkmc2/codegen/js/JSBuilder.scala | 10 +- hkmc2/shared/src/test/mlscript/HkScratch.mls | 18 +++ .../backlog/NonReturningStatements.mls | 2 +- .../src/test/mlscript/backlog/ToTriage.mls | 4 +- .../shared/src/test/mlscript/basics/AppOp.mls | 2 +- .../src/test/mlscript/basics/Assert.mls | 22 +--- .../src/test/mlscript/basics/BadDefs.mls | 4 +- .../mlscript/basics/BadMemberProjections.mls | 17 ++- .../src/test/mlscript/basics/BadParams.mls | 2 +- .../src/test/mlscript/basics/Declare.mls | 2 +- .../shared/src/test/mlscript/basics/Drop.mls | 4 +- .../test/mlscript/basics/DynamicFields.mls | 4 +- .../mlscript/basics/DynamicInstantiation.mls | 4 +- .../test/mlscript/basics/DynamicSelection.mls | 4 +- .../test/mlscript/basics/FunnyRecordKeys.mls | 12 +- .../mlscript/basics/MemberProjections.mls | 2 +- .../test/mlscript/basics/MiscArrayTests.mls | 8 +- .../test/mlscript/basics/MultiParamLists.mls | 8 +- .../mlscript/basics/MultilineExpressions.mls | 2 +- .../src/test/mlscript/basics/MutVal.mls | 2 +- .../mlscript/basics/PureTermStatements.mls | 2 +- .../mlscript/basics/ShortcircuitingOps.mls | 11 +- .../src/test/mlscript/basics/StrTest.mls | 2 +- .../src/test/mlscript/basics/Underscores.mls | 9 +- .../src/test/mlscript/codegen/BadNew.mls | 2 +- .../src/test/mlscript/codegen/BadOpen.mls | 2 +- .../src/test/mlscript/codegen/BasicTerms.mls | 10 +- .../test/mlscript/codegen/BlockPrinter.mls | 2 +- .../src/test/mlscript/codegen/BuiltinOps.mls | 12 +- .../test/mlscript/codegen/CaseShorthand.mls | 20 +--- .../test/mlscript/codegen/ClassMatching.mls | 11 +- .../src/test/mlscript/codegen/Comma.mls | 2 +- .../src/test/mlscript/codegen/ConsoleLog.mls | 11 +- .../src/test/mlscript/codegen/Formatting.mls | 18 ++- .../src/test/mlscript/codegen/FunInClass.mls | 4 +- .../src/test/mlscript/codegen/Getters.mls | 4 +- .../src/test/mlscript/codegen/GlobalThis.mls | 7 +- .../src/test/mlscript/codegen/Hygiene.mls | 4 +- .../test/mlscript/codegen/ImportExample.mls | 6 +- .../src/test/mlscript/codegen/ImportMLs.mls | 4 +- .../src/test/mlscript/codegen/ImportedOps.mls | 8 +- .../test/mlscript/codegen/InlineLambdas.mls | 8 +- .../src/test/mlscript/codegen/Inliner.mls | 5 +- .../src/test/mlscript/codegen/Lambdas.mls | 4 +- .../test/mlscript/codegen/MergeMatchArms.mls | 87 ++++++-------- .../shared/src/test/mlscript/codegen/Misc.mls | 2 +- .../src/test/mlscript/codegen/Modules.mls | 8 +- .../test/mlscript/codegen/NestedScoped.mls | 2 +- .../test/mlscript/codegen/OpenWildcard.mls | 8 +- .../test/mlscript/codegen/ParamClasses.mls | 30 ++--- .../src/test/mlscript/codegen/PartialApps.mls | 12 +- .../test/mlscript/codegen/PlainClasses.mls | 41 +++---- .../src/test/mlscript/codegen/PredefUsage.mls | 2 +- .../shared/src/test/mlscript/codegen/Pwd.mls | 2 -

The plain 

text dump is gone.

- ProjectSwitcher imports the editor module and stores the live
  EditorView on the component. renderPreviewBody mounts a new view only
  when the visible file actually changes (snapshot of dataset.previewPath
  on the body element + identity check on the view's DOM root); folder
  collapse / expand re-renders no longer thrash the editor instance.
- previewEntry replaces previewLookup + lookupFromFs, returning both
  content and mtime so the header can show when the file was last
  written. Snapshot wins for user files; fs.findNode is the fallback
  source for std files which live in the in-memory tree.
- The header is now a flex row: file path on the left (monospace, muted,
  ellipsized when long), formatted mtime on the right (monospace,
  subtle, never wrapping). When no file is selected both spans go empty.
- CSS sizes the body container as flex 1 with `.cm-editor { height:
  100% }` so the CodeMirror view fills available space and scrolls
  inside itself.

Subject: [PATCH 143/166] Treat the default project as a normal project
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous bootstrap hard-coded id "default" / name "Default project"
and re-inserted it on every boot, so deleting it was effectively impossible
— the next reload would resurrect it. Replace ensureDefaultInRegistry with
ensureAtLeastOneProject, which only fires on a genuinely empty registry
(first boot or wiped storage) and mints a project with a random id.

The legacy migration still writes its bucket under id "default" so
existing users' mlscript-fs:default:* keys keep resolving, but the
resulting registry entry is an ordinary project that respects the same
delete guards as everything else.

Also drive-by: the RegExp constructions in sanitizeForFilename needed
`new mut` to satisfy the type checker after the recent merge.

Subject: [PATCH 144/166] Export projects as ZIP with manifest, shared with
 Share dialog
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The project switcher's Export and the toolbar's Share buttons previously
produced two unrelated outputs — Export wrote a single JSON file with all
file contents inlined, while Share built a ZIP from scratch via an inline
JS helper. Unify both around one format and one builder:

  - New common/Zip.mls owns the ZIP primitives (writer + a small stored-only
    reader) and a download helper. ShareDialog drops its private copy and
    delegates here.
  - Every archive — from Export or Share — now contains manifest.json at
    the root with { schema: "mlscript-project/v2", exportedAt, project },
    followed by the workspace files at their original paths. Import knows
    to read the manifest, adopt the project metadata under a fresh id, and
    materialise the remaining entries via persistent.writeProjectFile.
  - Import accepts .zip (parsed in-browser via FileReader.readAsArrayBuffer
    + Zip.parse) instead of .json. The dialog hints and accept attribute
    are updated to match, and the schema bump to v2 lets us reject the old
    inline-JSON exports with a clear error.

+

+```
+
+Static row:
+
+```html
+

+  {label}
+  {value}
+

+```
+
+Add one delegated change listener. Changes from `.settings-toggle` and `.settings-select` should call `SettingsStore.setSetting(el.dataset.settingKey, value)`.
+
+### B0.9 Load persisted Settings values into the dialog
+
+Add `loadSettingsIntoDialog()`.
+
+Call it from `openDialog()`. It should:
+
+- find all elements with `data-setting-key`,
+- read their stored values with `SettingsStore.getSetting(...)`,
+- apply checked state for toggles,
+- apply selected value for selects.
+
+This must be generic and reused by all later settings rows.
+
+## Phase 1: Editor and Workbench Settings
+
+Each Phase 1 task should be small because Phase 0 supplies the store, dialog, tabs, and row templates.
+
+### B1.1 Add Editor font-size setting
+
+Add an Editor tab select row using key:
+
+```text
+editor.fontSize
+```
+
+Reuse the `--editor-font-size` variable from A2. Update `editor.mls` so editor creation applies the stored value.
+
+Expected result: the setting changes editor font size and persists across reload.
+
+### B1.2 Add Editor word-wrap setting
+
+Add an Editor tab toggle using key:
+
+```text
+editor.wordWrap
+```
+
+When enabled, include CodeMirror's `EditorView.lineWrapping` extension during editor creation.
+
+Expected result: long lines wrap only when the setting is enabled.
+
+### B1.3 Add Editor indentation-guides setting
+
+Add an Editor tab toggle using key:
+
+```text
+editor.indentGuides
+```
+
+When enabled, include the existing indentation-guide extension. When disabled, omit it.
+
+Do not reimplement indentation guides in this task.
+
+### B1.4 Add Editor show-whitespace setting
+
+Add an Editor tab toggle using key:
+
+```text
+editor.showWhitespace
+```
+
+When enabled, include `highlightWhitespace()` from `@codemirror/view`.
+
+Expected result: whitespace markers appear only when the setting is enabled.
+
+### B1.5 Add Reset Layout to Default action
+
+Add a Workbench tab button labeled:
+
+```text
+Reset Layout to Default
+```
+
+The action should clear exactly the layout and filter keys introduced in A5:
+
+- left sidebar width,
+- right sidebar width,
+- bottom panel height,
+- last active bottom tab,
+- Problems panel scope,
+- Logs level filter,
+- Logs source filter.
+
+Reload the app after clearing those keys. Do not clear project or file contents.
+
+### B1.6 Add startup Problems panel setting
+
+Add a Workbench tab toggle using key:
+
+```text
+workbench.showProblemsOnStartup
+```
+
+Wire it where the right rail's initial open/closed state is set in `IdeWorkbench.mls`.
+
+Expected result: users can choose whether the Problems panel opens on startup.
+
+### B1.7 Add reopen-last-project setting
+
+Add a Workbench tab toggle using key:
+
+```text
+workbench.reopenLastProject
+```
+
+Inspect `filesystem/projects.mls` to find where the initial project is selected. Make that behavior conditional on the setting.
+
+Expected result: users can disable automatic reopening of the previous project.
+
+## Phase 2: Compile and Run, Keyboard Shortcuts, and About
+
+### B2.1 Add default Problems scope setting
+
+Add a Compile & Run tab select row using key:
+
+```text
+problems.defaultScope
+```
+
+Options:
+
+- Workspace,
+- Current file.
+
+Update `DiagnosticsInspector.mls` so the selected value is used as the initial scope.
+
+### B2.2 Add default Logs level setting
+
+Add a Compile & Run tab select row using key:
+
+```text
+logs.defaultLevel
+```
+
+Update `BottomPanel.mls` so it uses this setting as the initial `logLevelFilter` instead of hardcoding `"all"`.
+
+Do not add a default source row. Log sources are built dynamically from log entries, so there is no stable option set at startup.
+
+### B2.3 Add Keyboard Shortcuts static list
+
+Add a static list in the Keyboard Shortcuts tab.
+
+Build the list from the shortcuts actually bound in `EditorPanel.mls`'s `handleShortcut` at the time this task is implemented. Do not copy a stale shortcut list from this document.
+
+Expected result: the Settings dialog documents the shortcuts that actually work.
+
+### B2.4 Add About version label
+
+Add a static version label to the About tab.
+
+Use a simple hardcoded string. `manifest.json` has no version field, so do not invent a new version source.
+
+### B2.5 Add About project link
+
+Add a static link to:
+
+```text
+https://github.com/hkust-taco/mlscript
+```
+
+This URL is confirmed from the repository remote. Do not substitute another project URL.
+
+## Phase 3: Larger Settings Work
+
+These tasks touch broader behavior or visual design. Do them last and review each one more carefully than the earlier Settings tasks.
+
+### B3.1 Add editor-only dark theme setting
+
+Add an Appearance tab toggle for the editor theme only.
+
+When enabled, swap `vscodeLight` to `vscodeDark` from the same `@uiw/codemirror-theme-vscode` package.
+
+This is explicitly not full workbench dark mode. Do not change workbench colors in this task.
+
+### B3.2 Add auto-compile-on-save setting
+
+Add a Compile & Run tab toggle for auto-compile-on-save.
+
+Wire it into `editor.mls`'s `saveOnChange` flow so saving conditionally dispatches `compile-requested`.
+
+This changes program flow, so verify that manual compile still works and that disabled auto-compile does not dispatch compile requests.
+
+### B3.3 Add auto-run-after-compile setting
+
+Add a Compile & Run tab toggle for auto-run-after-compile.
+
+Wire it wherever `compilation-status-change` emits `"done"` in `compiler/index.mls`. When enabled, successful compile completion should dispatch `execute-requested`.
+
+This changes program flow, so verify that manual execute still works and that failed compilation does not auto-run.
+
+### B3.4 Add Reset app to defaults action
+
+Add a Data tab button labeled:
+
+```text
+Reset app to defaults
+```
+
+Do not implement this as "clear all localStorage." Hardcode the exact list of keys to clear:
+
+- all `settings.*` keys,
+- the panel-size and filter keys from A5.
+
+Explicitly exclude any key that stores project contents, file contents, workspace contents, or user-created data.
+
+Require a native `confirm()` before clearing. If the exact key list cannot be confirmed with confidence, skip this task rather than guess.
+
+### B3.5 Reserve full workbench dark mode
+
+Leave the Appearance tab section for full workbench dark mode reserved but empty.
+
+Do not attempt this in an unattended batch. Full workbench dark mode needs actual design input for colors, contrast, and component states.
+
+---
+
+# Recommended Sequencing
+
+1. Complete Part A tasks that are independent and low risk.
+2. Complete A2 before B1.1, because B1.1 depends on the editor font-size variable and adjustment behavior.
+3. Complete A5 before B1.5, because Reset Layout needs the exact persistence keys.
+4. Complete all of Part B Phase 0 before any later Settings task.
+5. Complete Phase 1 and Phase 2 Settings rows before Phase 3 behavior changes.
+6. Run Part A9 documentation tasks after implementation work, not before.
+7. Use A10 only as stretch work after the main plan is stable.
+
+This plan currently contains 72 tasks. If an implementation task is skipped because the code already satisfies it, keep the task number reserved and note the skip in the relevant progress summary.
