What this does

Fills the gaps in the zh-hans catalog so the converted panels read in Chinese end to end, and routes a few strings that were drawn outside the catalogs through them.

Commits

  • i18n: add 1087 Simplified Chinese rows for panels, dialogs and tooltips
  • i18n: route dock panel tabs and workspace names through the catalogs
  • i18n: translate the project and timeline column headers, the search placeholders and the dock's computed panel titles
  • style: apply rustfmt to the zh-hans catalog and dock tab changes

How the rows were chosen

1468 English literals were collected from crates/ui-egui/src and reviewed one by one. 1226 were translated; 242 were deliberately left alone because they are key names, colour-space identifiers (Rec.2100, ACEScg), template tokens or array keys such as blue[0].

1087 of the 1226 land in ui.rs. The rest belong to the menu catalog in i18n.rs and are covered there.

Two filters keep the catalog tests green:

  • rows whose English carries a named placeholder ({name}) are excluded, because tr_args only understands {};
  • every row added is requested by a tr() / tr_args() call in a CONVERTED panel, so every_row_is_used_by_a_converted_panel keeps passing.

TRADITIONAL_CHINESE receives the same rows in the same order (OpenCC s2t), because the two Chinese catalogs must stay identical and in step.

Wiring

The catalogs are only half the story: several strings were drawn by code that never asked for a translation.

  • dock_ui.rs: dock tab titles resolve through i18n::label(self, "window.panel", …), which already carries the Chinese wording, falling back to PanelKind::title().
  • header.rs: the workspace bar runs its labels through tr().
  • widgets.rs: field() translates its own hint, so every search and text field gets a translated placeholder from one place.
  • panels/project.rs and panels/timeline.rs: the column headers (Name, Type, Size, Label, Keys, Layer/Source Name, Comment, Mode, Track Matte, Parent & Link, In, Out, Duration, Stretch) and the show/hide-columns and blank-area context menus.
  • Computed titles such as "Effect Controls {}" are built from the window.panel label plus the layer's own name, so project content stays verbatim.

Tests

  • cargo test -p effectcraft-ui-egui i18n --release: 40 passed, 0 failed
  • cargo fmt --check: clean
  • cargo clippy -p effectcraft-ui-egui --release -- -D warnings: no warnings
  • cargo test -p effectcraft-ui-egui --release: 270 passed, 2 failed, 3 ignored — see below, both failures are pre-existing and language-dependent.

The two failing tests

native_menu::tests::every_engine_entry_is_in_the_native_menu and panels::templates::tests::my_custom_rgb_dialog assert English menu labels. On a machine whose interface language is Chinese they read the translated labels from the menu catalog in i18n.rs, which this change does not touch, and fail. Both pass on an English-language machine, which is what CI runs. I left them alone rather than weaken an existing assertion; say the word if you would rather have them pinned to English.

Not covered (known gaps, deliberately out of scope)

  • Property names (Transform, Anchor Point, Position, Scale, Rotation, Opacity) come from the document model rather than the UI catalogs.
  • Effect parameter names, roughly 1650 strings — already recorded as a gap in docs/localization-parity.md.

I would be happy to follow up on either in a separate PR if you would like that channel opened; I did not want to change the document model inside this one.

Summary by CodeRabbit

  • New Features
    • Added Simplified and Traditional Chinese translations for interface labels, controls, dialogs, and commands across project, rendering, text, tracking, and viewer areas.
    • Translated project context-menu labels, timeline column headers, and search and text-field hints, making more of the interface available in the selected language.

Fills the gaps in the zh-hans catalog so the converted panels read in
Chinese end to end: composition and render settings, the render queue,
text and tracking panels, the paint and viewer surfaces, forms, dialogs
and status messages.

Scope of this commit:

* 1468 English literals were collected from crates/ui-egui/src and
  reviewed. 1226 were translated; 242 were deliberately left alone
  (key names, colour-space identifiers such as Rec.2100 and ACEScg,
  template tokens and array keys like blue[0]).
* 1087 of the 1226 land in the ui.rs catalog. The rest belong to the
  menu catalog in i18n.rs and are covered separately.
* Rows whose English carries named placeholders ("{name}") are excluded:
  tr_args only understands "{}".
* Every row is requested by a tr()/tr_args() call in a CONVERTED panel,
  so every_row_is_used_by_a_converted_panel keeps passing.
* TRADITIONAL_CHINESE gains the same rows in the same order
  (OpenCC s2t), because the two Chinese catalogs must stay identical.

cargo test -p effectcraft-ui-egui i18n: 40 passed, 0 failed.
The dock tabs (Project, Timeline, Effect Controls, Render Queue, ...)
and the workspace bar (Standard, Small Screen, Learn, Review, Default)
are drawn by the docking shell and the header themselves, so they never
consulted a catalog and stayed in English even with zh-hans selected.

* dock_ui.rs: resolve each tab title through i18n::label(self,
  "window.panel", ...), which already carries the Chinese wording in the
  menu catalog, and fall back to PanelKind::title().
* header.rs: wrap both workspace labels in tr().
* ui.rs: add the five workspace names to both Chinese catalogs.

The five workspace rows are unique: "Learn" and "Default" already had a
row, so those two are reused instead of being listed twice
(catalogs_are_unique_and_keep_the_english_shape).

cargo test -p effectcraft-ui-egui i18n: 40 passed, 0 failed.
placeholders and the dock's computed panel titles

The second wave of English left on screen after the catalogs were filled.

* widgets.rs: field() asks the catalog for its hint, so every search and
  text field translates its placeholder ("Search project", ...).
* panels/project.rs: the column headers (Name, Type, Size, Label) and the
  blank-area context menu (New Composition…, New Folder, Import File…).
* panels/timeline.rs: the column headers (Keys, Layer/Source Name,
  Comment, Mode, Track Matte, Parent & Link, In, Out, Duration, Stretch)
  and the same labels in the show/hide columns menu.
* dock_ui.rs: the computed tab titles ("Effect Controls {}", "Properties:
  {}") are built from the window.panel menu label plus the layer's own
  name, which stays project content.
* ui.rs: add New Folder, Mode and Track Matte; "Type" is the project
  panel's Type column and the camera dialog's Type row, so 类型 rather
  than 文字.

cargo test -p effectcraft-ui-egui i18n: 40 passed, 0 failed.
The injected rows were written wrapped, but rustfmt.toml asks for
max_width = 160 with use_small_heuristics = "Max", so
`cargo fmt --check` (the first step of `cargo xtask ci`) failed on three
files.

Reformat with cargo fmt. Only files this branch already touched are
affected, so the diff stays scoped to the i18n work.

cargo fmt --check: clean.

Walkthrough

The Simplified and Traditional Chinese catalogs gain additional interface translations. The project background button, timeline headers, and text-field hints now use translation lookups. A dock comment distinguishes a panel menu label from project content.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Translate the column-visibility menu labels.

The project header now translates column labels, but column_menu passes the raw label to ui.checkbox. The same columns therefore appear translated in the header and English in the visibility menu.

Pass crate::i18n::tr(label) to the checkbox.

Translate workspace names in the context menu.

The popup and visible tabs use translated labels, but ws_menu passes each original workspace name directly to ui.selectable_label. The context menu therefore remains English in a translated interface.

Keep the original name for comparison and pass crate::i18n::tr(&w) only to the displayed label.

Translate the fallback for viewer panels.

PanelKind::Viewer(_) is not in PanelKind::ALL. A new viewer can have no assigned composition, so viewers::title() returns None. The viewer then reaches line 219 and displays the English Composition fallback.

…ace titles

Upstream has since routed dock panel titles and the workspace bar through
`command_label`, which reads the menu catalog and falls back to this panel
catalog. Our calls did the same job through `i18n::label` and `tr`; where the two
met, upstream's call stays and the comment explaining why the panel's own name
is interface text and only the layer's name is project content is kept.

Two rows we had added are dropped, both cases of translating something that is
not interface text:

- "Comp 1": a composition's name is the user's. Translating it also broke
  `command_label_reads_the_menu_row_then_the_panel_row`, which expects a lookup
  miss to leave the source alone.
- "Composition {}": the viewer tab now builds its title from the menu row for
  "Composition" plus the composition name, so this row has no caller.

Hi @linzhang779-maker, thanks for this PR! main has changed a lot since it was opened, and it now conflicts with main, so it needs a rebase before we can review it for merging.

When you rebase, please also make sure it fits the other recent changes:

CI (cargo xtask ci) now runs on PRs. Once it's green on the rebased branch, we'll take a look. Thank you!
