Render control characters in tab titles and project panel entries (#62875)
# Objective Fixes #62664 File names may contain control characters (`\n`, `\r`, `\t`, …) on most platforms. Zed rendered them verbatim, so a file named `notes\ndraft.md` broke the layout of its tab and of its project panel entry instead of showing a readable name. The same held anywhere else a name reached the screen without going through `Label::single_line`. ## Solution The substitution lives in one shared place, `ui::utils::replace_control_characters`, reached through `Label::single_line`. `\n` keeps rendering as the `⏎` Zed already used, so nothing that renders correctly today changes; every other C0 control character maps onto the Unicode "Control Pictures" block by a single rule (`U+2400 + code point`), giving `␉` for tab and `␍` for carriage return. `DEL` maps to `␡`. C1 controls are left alone, having no equivalent there. Where that is wired in: - **`Label::single_line`** — replaces its previous `\n`-only substitution. The project panel already used it everywhere, including folded directory components, so the panel is fixed by this alone. - **Editor tabs** and the **default `Item::tab_content`**, neither of which called `single_line`. - **Terminal tab titles**, which render through their own `tab_content`. Those titles come from OSC escape sequences, so the control characters in them are attacker-controlled. - **`HighlightedLabel::single_line`**, which never substituted anything — not even `\n`. See below. - **The file finder**, for both the file name and the path. - **Nine `tab_content` overrides in git_ui**, by deleting them. - **`HighlightedMatchWithPaths`**, for both the match label and its paths — it backs the tab switcher and the outline panel, among others. ### `HighlightedLabel` needs its offsets moved, not just its text Its highlight indices are byte offsets, and every stand-in is wider in bytes than the character it replaces, so the offsets have to move with the text. Left alone they index into the middle of a character, and `highlight_ranges` slices the string at exactly those offsets — which panics in release builds too. The constructor's `debug_panic!` does not cover this, since `single_line` runs after construction. So `replace_control_characters_remapping_offsets` substitutes and remaps in one pass, over an old-to-new byte offset table built the way `ensure_uniform_list_compatible_label` does it in `lsp_store`. This also fixes the call sites that already asked for a single line, including the branch picker and the tabular column filter values. ### Deleting the git_ui overrides Nine files replicated the default `Item::tab_content` verbatim except for the colour, hardcoding `selected ? Default : Muted` instead of `params.text_color()`. Deleting them lets those tabs inherit the fixed default, and fixes a second bug along the way: none of them dimmed when the pane lost focus. Titles and icons are unaffected — they come from `tab_content_text` and `tab_icon`, which the default calls. `git_graph.rs` already did it this way. ### Tabular column headers These never went through a `Label` at all: the raw `SharedString` was a child of a `div`. They now display stand-ins, while right-click-copy still yields the real column name. Two notes for reviewers: - Both helpers avoid allocating when there is nothing to replace, so the common path is untouched. The previous `self.label.replace('\n', "⏎")` allocated a `String` on every render for every label — including every visible project panel entry, every frame. - Every stand-in is exactly one character, so character offsets are preserved and the existing `truncate_and_trailoff` math on tab titles stays correct. ## Testing - Unit tests cover both helpers: each control character's substitution, repeated occurrences, multi-byte characters (accents, emoji), the borrow-vs-own behaviour, the preserved character count, C1 passthrough, and — for the remapping — offsets before, at and after a replacement, offsets at and past the end, and the invariant that every remapped offset lands on a character boundary. - Unit tests cover `Label::single_line` and `HighlightedLabel::single_line`, the entry points every call site uses. `highlighted_label.rs` had no tests before. - `cargo test -p ui -p file_finder -p workspace -p project_panel -p git_ui -p git_ui_core -p terminal_view -p tabular_data_preview` passes (774 tests), as do `cargo clippy` and `cargo fmt --check`. - No existing test changes behaviour: tests assert on `tab_content_text`, which is untouched; only rendering paths changed. - Verified manually on macOS (aarch64) — see Showcase. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments — none added - [x] The content adheres to Zed's UI standards - [x] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable ## Showcase A directory holding `report<TAB>table.csv`, `notes<LF>draft.md`, `carriage<CR>return.txt` and a normally named `normal.txt`, all four open as tabs. **Before**  **After**  Three things change: 1. **The `notes<LF>draft.md` tab** is the clearest one. Before, the literal newline splits the tab across two lines — `notes` above `draft.md` — distorting the whole tab bar. After, it stays on one line. 2. **`carriage<CR>return.txt` in the project panel** renders as `carriagereturn.txt` before: the `\r` is completely invisible, so the name reads as one word and there is no way to tell a character is there. After, it renders as `carriage␍return.txt`. 3. **`report<TAB>table.csv`** shows a bare gap before, indistinguishable from a space. After, it renders as `report␉table.csv`. Note that `notes<LF>draft.md` looks the same in the project panel in both shots: that entry already called `single_line`, which already handled `\n`. That is precisely the asymmetry this PR removes. ### File finder Before, the newline also breaks the list itself — the `notes<LF>draft.md` row grows to two lines and overlaps the row beneath it. **Before**  **After**  Searching for `table` exercises the offset remapping, the match falling after the control character: **Before**  **After**  One thing this PR does **not** cover: the breadcrumb below the tab bar still renders the raw tab character, as it goes through a different path. ## Release Notes: - Fixed file names containing control characters, such as tabs and newlines, rendering unreadably in tabs, the project panel, the file finder, the tab switcher and terminal tab titles. --------- Co-authored-by: Kirill Bulatov <kirill@zed.dev> |

tabular_data_preview: Finish generalizing crate naming (#62807)
# Objective #62768 renamed `crates/csv_preview` to `crates/tabular_data_preview`, but left the CSV-specific names inside it untouched (on purpose, to reduce prev PR scope & git diff noise) ## Solution Finished the generalization, one mechanical rename per commit for easier review: 1. `CsvPreviewView` -> `TabularDataPreviewPane` 2. `CsvPreviewSettings` -> `TabularDataPreviewSettings` 3. Methods/vars 4. Test helpers/fn names 5. User-facing strings and element ids: tab title fallback: - `"CSV Preview"` -> `"Tabular Data Preview"`, - empty state `"No CSV content to display"` -> `"No data to display"`, - dev tooltip, and element ids `csv-filter-*`/`csv-col-header-*`/`csv-table`/`csv-display-cell-*` -> `table-*`/`tabular-data-table` 6. Doc comments that implied CSV-only behavior, reworded to be format-agnostic > NOTE: PR is split into commits by change type for ease of review) ## Testing `cargo check -p tabular_data_preview -p zed` builds clean after each commit; `cargo test -p tabular_data_preview --lib` passes (10/10). ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [ ] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [x] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable Release Notes: - N/A |

Rename csv_preview crate to tabular_data_preview (#62768)
# Objective #60768 renamed the feature (action names, icon, TSV/PSV/SSV support) from CSV-only to generic tabular data preview, but left the crate itself named `csv_preview` — no longer accurate now that it handles any delimited format. ## Solution Renamed `crates/csv_preview` to `crates/tabular_data_preview` and updated all references (workspace `Cargo.toml` members/dependencies, `crates/zed/Cargo.toml`, `crates/zed/src/main.rs`, `crates/zed/src/zed/quick_action_bar/preview.rs`). No behavior change. > NOTE: Mechanical changes. Internal structs not renamed on purpose to reduce git diff noise. Follow-up PRs will do the cleanup (also mechanical changes) ## Testing `cargo check -p tabular_data_preview` and `cargo check -p zed` build clean; preview still opens for csv/tsv/psv/ssv files. Zed still runs, everything still opens. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [ ] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable Release Notes: - N/A --------- Co-authored-by: MrSubidubi <finn@zed.dev> |
