EPS: Save As shows Use Artboards, off by default, and the box fits all visible art - #6751
Save and Save As as EPS always wrote the chosen artboard as the page and %%BoundingBox, and the EPS Options hid Use Artboards, so art past the artboard was left outside the file's bounding box.
The EPS Options of Save As now show Use Artboards with All or Range under it, for a separate file per artboard (saving in EPS). It is unchecked by default: the scripting reference's EPS save options list saveMultipleArtboards with a default of false (scripting reference).
Unchecked, Save writes one file whose bounding box fits all the visible art, as Export does, without the artboards' background colors. With no visible art the page is the first artboard, in its color.
Checked with two or more artboards, the file at the path is the central file of the visible art, and each artboard is also written to <name>_<artboard>.eps beside it.
The file the document becomes still carries the whole editable document. selectedOnly stays an Export option, and Save refuses it.
artboard, artboards or range in a save still turn Use Artboards on. file.formatOptions now reports it on, with those artboards as the range, and the Save As dialog opens that way.
Changed default: an EPS saved with Save or Save As, an opened EPS included, now gets a bounding box around its visible art unless Use Artboards is checked or the save names artboards. An opened EPS saved back this way loses the margins its page had.
The params text of document.save and file.formatOptions, the useArtboards option text, docs/mcp.md, docs/file-format-parity.md and the evidence line in docs/target-app-parity.md are updated. The earlier EPS Save evidence notes in docs/gaps.md, docs/roadmap.md and docs/target-app-parity.md now say what changed.
How it was tested
New or changed tests, each shown failing without the change:
dialogs::save_options::tests::eps_save_as_shows_use_artboards_off_and_writes_the_art_or_the_artboard: the box matches Export's, the other save formats do not gain the row, and an artboard named by an earlier save opens the dialog checked on that artboard.

The gate failed on 61ac0ce2f4, the merge of main: the merge had dropped the app's check of the files written beside the path against the file the document was read from. 95d90511e restores it. The files written beside the path also ask before replacing a file that is there, as #6830 added, and tests::save::an_eps_save_with_use_artboards_asks_before_replacing_an_artboard_file_that_is_there covers that for EPS artboard files.

Summary by CodeRabbit
Bug Fixes
Saving no longer overwrites an imported source that may have lost content unless you acknowledge the loss. This protection also covers files generated alongside multi-artboard EPS exports, preventing partial changes when a save is refused.
When generated artboard files already exist and are not the imported source, saving prompts before replacing them. Canceling leaves the files unchanged; confirming completes the export.
Saving can proceed when you acknowledge the import losses.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Save plans retain information about lossy imported sources. Before writing, the save job checks generated output paths against that source. UI save flows rebuild plans after save options are selected. Tests cover overwrite refusal and replacement confirmation for artboard outputs.

[Feature] Missing EPS save as/export/import #1933: The PR changes EPS Save As behavior, which overlaps with part of the issue’s requested EPS save capability. It does not establish broader EPS import or export support.
Suggested reviewers:bflatastic, mockydevs
Merge Risk: Moderate · up to 5006b
An ordinary Save of a lossy EPS import with Use Artboards enabled can overwrite the original imported file through a generated artboard sibling without any loss acknowledgment. The exposure is narrow, but the result is silent data loss. Replan the ordinary Save path from the original parameters, as the other save paths already do, before merging.

Explanation
The title names the two main parts of the change: EPS Save As showing Use Artboards (off by default) and the bounding box fitting all visible art. It is specific and matches the changeset and the PR objectives. It is long (82 characters, 16 words) but still describes the primary change.
Full details: Description check
Explanation
The description follows the template's sections: What and why, How it was tested, and Checklist. It explains the motivation, the new Use Artboards behavior, the default change, the documentation updates, the tests run, and CI status. It links the issue context and the reference sources. The main gap is that the 'What and why' section does not link a tracked issue, and the top-level CI checklist item is left unchecked, which the author explains as pending. These are non-critical gaps.

3fd653a: a save with useArtboards: true that named an artboard with artboard or artboards, and no range, wrote that artboard, but file.formatOptions reported the default range, so Save As opened on All and OK saved every artboard. file.formatOptions now reports those artboards as the range unless Use Artboards was saved off. The new test tests::save::eps_save_with_use_artboards_and_a_named_artboard_reports_it_as_the_range fails without the change. The branch still merges cleanly with main.

destination, using the existing `acknowledgeLoss` setting, before writing any
file. Update the save flow around `per_artboard` to check all sibling paths up
front, so a refused destination cannot leave a partial set of files.

…file read from
A save with Use Artboards writes a file per artboard beside the path. Each of them is now checked against the file the document was read from, before the first file is written, so a sibling cannot replace that file without acknowledgeLoss. The interface checks the files beside the path the same way.
Approved and green, but main has since changed files this touches, so this CI run predates them. Could you rebase so CI runs on current main? It'll go in once that run is green.
… from again
The merge of main kept main's calls to write_plan, which plan the save
with acknowledgeLoss set, so a save in the app no longer refused to
replace the file the document was read from when that file was one
written beside the path (an EPS artboard file). The save is planned
again without it before it is written, as before the merge.
The files a save writes beside the path still ask before replacing a
file that is there, except those the document's last save wrote. A new
test covers an EPS save with Use Artboards meeting artboard files from
another document: it asks, Cancel writes nothing, OK writes every file,
and the next Save does not ask.
Approved, but this conflicts with main again after today's merges. Could you rebase once more? It'll go in as soon as CI is green. Sorry for the churn, main is moving fast today.

Replan ordinary Save without forced loss acknowledgment.
save_current_in builds first with acknowledged(p). This sets SavePlan.lossy_source to None, so the new generated-output guard does not run.
After a lossy EPS import is saved under another name, an ordinary Save with Use Artboards can generate a sibling at the imported source path. ask_before_losing checks only the main path. The sibling can therefore replace the source without acknowledgment.
After the confirmation check, rebuild the plan from the original p, as the changed save_suggesting branches do.
Based on learnings, replacing a lossy imported source requires acknowledgeLoss: true.

Ensure the generated-output guard requires acknowledgeLoss when a sibling would replace the imported source, while preserving the existing confirmation flow.

File > Save to the document's own file planned the save with acknowledgeLoss
set, so that only its own path was asked about, and then wrote that plan. With
the acknowledgment in the plan, the files written beside the path (an EPS
saved with Use Artboards writes one per artboard) were not checked against the
file the document was read from. A document opened from one of those artboard
files, with things left out when it was read, was written over by File > Save
without the question. Save As and Save a Copy already plan again without the
acknowledgment before writing; File > Save now does the same.
