Summary

The Script pane had only Run and Commands… under its box: starting a new script meant deleting the old one by hand, and the last run's results and Run #N line stayed until the next run.

• Clear, beside Run and Commands…, empties the pane as opening another project does ([Bug]: The Script pane keeps the previous project's script and results after another project opens #1511): the script, the results and the count (the next run is Run #1 again), and an open Details… window closes. Both now go through one function, clear_script.
• No confirmation, Ctrl+Z instead. egui's text box records undo steps only while it has the focus, so a script typed or loaded and cleared without clicking in the box first would have nothing to go back to. Clear stores the script as an undo step of the box first, as picking a suggestion does (scriptcomplete::accept), and gives the box the focus: Ctrl+Z (⌘+Z) brings the script back at once. The tooltip says so.
• Off with nothing to clear, and while a run is under way on the desktop ("Wait for the run to finish"), whose results would land in the emptied pane.
• Only the pane changes: the project, the map, the Session log and the project's undo are left alone.
• Not a command, on purpose. The undo step that makes Clear safe lives in the text box's state, which only the pane can reach: a command run from search, the CLI or a shortcut would empty the pane with no way back. Like Details… and the flows pane's Clear, it acts only on the pane's own state, and scripts can't run ui.* commands.
• User guide: the Script pane section in docs/user-guide/analysis.md describes Clear, and that after a click elsewhere Ctrl+Z undoes in the project, so the box needs the focus first.

Testing

• New test clear_empties_the_script_pane_and_undo_brings_the_script_back: a pointer click on Clear empties the script, results and count and closes Details; the box keeps the focus; the button is off with nothing left; Ctrl+Z brings the script back without its results; the button is off while a run is under way. Without the stored undo step, the Ctrl+Z check fails.
• another_project_starts_the_script_pane_blank still passes through the shared clear_script.
• cargo fmt --all --check, cargo clippy -p rustgis-ui-egui --all-targets -- -D warnings, cargo test -p rustgis-ui-egui --lib -- analysispane scriptcolor scriptcomplete (98 passed).

Summary by CodeRabbit

• New Features
  • Clear now empties the script, results, run count, and Details window, and keeps the editor focused so you can restore the script with Ctrl+Z.
  • Clear is unavailable when there is nothing to clear or a run is in progress. Starting a new project also clears the Script pane and closes Details.
• Documentation
  • Updated the analysis guide with Clear behavior, undo details, and availability conditions.

Walkthrough

The Script pane now has a Clear button that empties the script and run state, closes Details, and preserves script undo through Ctrl+Z. Project changes use the same clearing behavior. The button is disabled when the pane is empty or a run is pending.

Changes: Script pane clearing

Layer / File(s)	Summary
Shared clearing behavior crates/ui-egui/src/analysispane.rs	A shared helper clears the script, output, last run, and Details state. Opening another project now uses this helper.
Clear action and validation crates/ui-egui/src/analysispane.rs, docs/user-guide/analysis.md	The Clear button records the script for undo, clears pane state, and restores editor focus. It is disabled when the pane is empty or a run is pending. The UI test and guide cover these behaviors. The Run shortcut label uses a locally stored platform check.

Change: Feature · Severity of issue fixed: Low

Possibly related issues

• Issue 1511 concerns clearing the Script pane when another project opens. This change routes that project-change behavior through the shared clearing helper.
• Issue 1515 concerns the Details window for the last run. This change closes the window when the pane is cleared.

Possibly related PRs

Suggested reviewers: giswqs

Merge Risk: Low · up to e72dc

The change is mergeable with awareness of two minor edge cases: undo can appear ineffective after clearing an empty script, and an old project's pending run can temporarily prevent clearing the new pane.

Full details: Title check

Explanation

The title names the main change: a Clear button that empties the Script pane, with the script recoverable through Ctrl+Z. The changeset adds this button, the shared clear_script helper, undo-step handling, focus handling, and disabled states, so the title matches the primary change. It is long at 85 characters, and its wording ("its script back") is slightly awkward, but it remains specific and descriptive.

Full details: Description check

Explanation

The description follows the repository template. It has a Summary that explains the Clear button, the reason for the change, and the no-confirmation/Ctrl+Z design. It has a Testing section listing a new test, the existing test that still passes, and the fmt, clippy, and test commands run. It has a UI evidence section with before/after screenshots, which the template requires when UI changes. The Related issue section states Closes #1567. The template's 'No visible UI change' line was correctly replaced because this PR changes visible UI.

Full details: Linked Issues check

Explanation

[#1567] is the only directly linked active issue. Its coding requirements are: (1) a Clear button beside Run and Commands… that empties the script, results, and Run #N count; (2) the next run is Run #1; (3) an open Details window closes; (4) no confirmation, with the box focused so Ctrl+Z (⌘+Z) restores the script and the tooltip says so; (5) disabled when nothing is clearable or while a desktop run is under way; (6) the project, map, Session log, and project undo are unchanged.

Code evidence at head e72dc78:

• script() adds ui.add_enabled(anything && !running, Button::new("Clear")), placed after Commands…. anything checks script, script_out, and script_last. running checks script_started. The disabled hover text is "Wait for the run to finish".
• The tooltip reads "Empty the script and its results ({keys} brings the script back)", with the platform key label.
• clear_keeping_undo loads the TextEditState, adds the current script as an undo step, moves the cursor to 0, stores the state, calls clear_script, and calls request_focus(box_id).
• clear_script clears script, script_out, and script_last, and sets script_details to false. It touches no project, map, log, or project-undo state.
• start_over_in_another_project now calls clear_script, so the #1511 path is unchanged in effect.
• The test clear_empties_the_script_pane_and_undo_brings_the_script_back covers the click, the empty state, Details closing, focus, the disabled state with nothing left, Ctrl+Z restoring the script without results, and the disabled state while a run is under way.

The disabled check tests any non-empty script_started. It does not test a desktop-only cfg. This is a superset of the issue wording and does not fail the requirement. The issue's alternatives (results-only clear, two buttons, confirmation dialog, ui.* command) are not implemented, which matches the requirements.

Full details: Out of Scope Changes check

Explanation

All changed code is connected to #1567 and its scope.

• analysispane.rs: the Clear button, clear_keeping_undo, and clear_script implement the requirements. start_over_in_another_project now calls clear_script. This is a shared-helper refactor that keeps the #1511 behavior. The mac local is extracted so the Run and Clear shortcut labels share one platform check. This supports the new tooltip.
• Tests: the one new test covers the new behavior. The existing another_project_starts_the_script_pane_blank test still exercises the shared path.
• docs/user-guide/analysis.md: describes Clear, its focus and Ctrl+Z behavior, and its disabled states. This documents the new feature.

No change touches the project, map, Session log, project undo, ui.* commands, or other panes. The diff at head shows no unrelated edits. One refinement is noted: clear_script sets script_details to false in the other-project path. The existing user guide already states that Details goes with the old project, so this matches documented behavior.

Code review

I read the diff, the surrounding code and the base-branch AGENTS.md, and checked the undo path against scriptcomplete::accept and the app's Ctrl+Z handling. I could not run the tests or clippy here (no shell), so the new test is unverified.

Bugs

• None found. The undo-point pattern matches scriptcomplete::accept. The app defers Ctrl+Z to a focused text field (keymap.rs is_text_undo), so the restore works in the real app. No unwrap/expect in the new code.

Security

• None found.

Performance

• None found.

Quality

• Low confidence (~35%): the Clear undo step lives in the box's TextEditState, which persists for the session. After Clear and then opening another project, Ctrl+Z in the new project's box can restore the old project's script. Typed text already behaves this way; Clear makes it the most recent step. Inline on analysispane.rs:1584.
• Nits, grouped: clear_script_pane and clear_script are easy to confuse, and the doc comment on clear_script_pane is hard to follow. Left for the release quality pass.

AGENTS.md

• Low-medium confidence (~40%): "Everything is a command". Clear changes pane state directly from the button handler, so it is not reachable from command search, shortcuts or the CLI. Inline on analysispane.rs:1779.
• The PR is a visible UI change, and AGENTS.md asks for before and after screenshots. The body says they are "to follow", so this is not yet met. This is a PR-level point, not an inline one.
• The user guide says Ctrl+Z restores the script, but the restore only works while the box has focus. Inline on docs/user-guide/analysis.md:1183.

Prior reviews: no earlier threads on this PR, so nothing was left out as already raised.

Applied in e72dc78: the guide's focus note, and the renamed clear_keeping_undo with a shorter comment. The two other points are answered inline. Screenshots are in the PR body.

Code review

I found no new bugs, security issues or performance problems. I read the diff and the code around it: the Script pane's box and buttons, scriptcomplete::accept, the text-field routing of Ctrl+Z in chrome.rs, and the stale-list check in scriptcomplete::keys. I did not build or run the tests, so the undo behaviour rests on reading the code and the test, not on a run. No inline comments: nothing new cleared the bar.

Bugs

• None new.

Security

• None.

Performance

• None.

Quality

• Hover text when there is nothing to bring back (analysispane.rs:1774, confidence ~50%): the tooltip "Empty the script and its results (Ctrl+Z brings the script back)" is also shown when the script is already empty and only results remain. Ctrl+Z then brings back nothing. Left for the release quality pass, as a wording point.

AGENTS.md

• All new user-visible literals use tl! or i18n::fmt. Command ids are untouched. Layering is unchanged (UI only). The PR's screenshots are attached to the PR, which the guidance allows.
• Two concerns from earlier threads still stand and are left alone because they were already raised: the stored undo point survives a project switch, and Clear changes pane state from the button rather than through a CommandSpec (confidence ~35–40%).

Earlier review threads

• Three threads exist. Two are unresolved and left alone (above). The third, on the Ctrl+Z wording in the docs, is addressed by this PR's revised text in docs/user-guide/analysis.md, so it is not re-raised.
• Concerns left alone because already raised: 2.

Code review

Reviewed the 2-file diff (analysispane.rs, analysis.md) against AGENTS.md and the surrounding code (start_script, script_ran, scriptcomplete::accept, the new Clear test). The undo-step pattern matches scriptcomplete::accept, there are no unwrap/expect/panic in the new code, UI strings go through tl! and i18n::fmt, and the PR includes before/after screenshots.

Bugs: None confirmed.

Security: None found.

Performance: None. The extra script.clone() on Clear is a single small string copy on a user click.

Quality

• Low confidence (~35%): Clear is disabled whenever script_started is non-empty, and that queue is app-wide. A run asked in a project that was since replaced keeps the button off with "Wait for the run to finish" in the new project. The wait is finite, so this is a UX surprise rather than a bug. Inline comment posted at crates/ui-egui/src/analysispane.rs:1769.
  • Correction to that comment: it says a replaced project's run "can't write into this pane". That holds only for runs that did not run (NotRun or Err). A run from a replaced project that ran successfully (a script that opened a project) still lands here by design. The comment should be read with that correction.
• Nit (grouped, not posted inline): docs/user-guide/analysis.md:1181-1185 reflows awkwardly. The line ending "off with nothing to clear, and while a run is under way. Opening a" breaks mid-sentence, so the paragraph wraps oddly.

AGENTS.md

• Already raised and answered in the prior threads, so not re-raised: "Everything is a command" (Clear is UI-only on purpose), undo history carrying across projects (author deferred to a follow-up), and the Ctrl+Z focus wording (fixed in e72dc78).
• No new violations found.

Prior concerns left alone: 3 (the undo-across-projects thread, the command-ness thread, and the docs focus thread).

Thanks. The three new points are answered inline (the docs wrap is source line breaks; it renders as one paragraph). No code change in this round.
