html: a page on one line, and styles in a sheet or in attributes by donislawdev · Pull Request #179 · donislawdev/TestingFilesGenerator

What changes for a user

formatting (lines / minified, default lines): minified puts the whole page on one line with no newline at the end. It shows the same as the page in lines. The catalogue of every element keeps a space where a line ended, and the line break inside its pre becomes 
. The manifest says line_ending: none for such a page.
styles (none / embedded / inline, default none): one list of CSS rules, written as a style element (in the head of a page, at the very start of a fragment) or as a style attribute on every heading, paragraph, list, table and quote the page is filled with. Nothing in the CSS names an address to fetch.
The defaults write the same bytes as before (golden hashes unchanged, three new ones pinned).

Measured on pages from this program

Nu HTML Checker 26.10.12: every page clean. Fragments carry only the two errors a fragment has without CSS.
Chromium 152: one line and lines lay out identically. So do embedded and inline, apart from the catalogue, which only the sheet styles.
DOMPurify 3.4.17 with its defaults drops the style element without listing it as removed and keeps every style attribute. lxml's text_content and BeautifulSoup on html5lib count the rules as text.
Go's bufio.Scanner refuses a 2 MB page on one line (token too long).

How it is built

Every piece of markup a page writes is one entry of an array (htmlfile/markup.go). The other five spellings come from the plain one through two rules applied to every piece, so a new piece is covered by both rules. The structural check is told both settings and asserts them.

Test plan

Golden hashes and the default-bytes guards
Four new guards in htmlstyles_test.go. Six hand mutations, all caught
Cheap gates, parity, sentence catalogues, html guards. Only the two known reds, with unchanged numbers
golangci-lint 0 issues, journey.py 348/348
Window rendered in English and Polish, including the refusal below the minimum

Summary by CodeRabbit

New Features
- HTML output now supports minified, single-line formatting and configurable CSS placement: embedded in a style element or applied inline to generated elements.
- HTML settings and manifests now reflect the selected formatting and style options.
Updates
- Inline pictures appear above content blocks, each in a separate paragraph.
- Documentation and validation messages now describe the HTML formatting and style options.

formatting=minified puts the whole page on one line with no newline at the end, and it shows the same as the page in lines. The catalogue of every element keeps a space where a line ended, and its pre keeps its line break as a character reference. The manifest says line_ending none. styles=embedded puts one list of CSS rules in a style element, in the head of a page and at the very start of a fragment. styles=inline puts the same rules in a style attribute on every element they are for, outside the catalogue. No rule names anything to fetch. Every piece of markup a page writes is now one entry of an array, and the other spellings are made from the plain one by two rules, so the default bytes are unchanged. The structural check is told both settings and asserts them, four new guards, three golden hashes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 Walkthrough

HTML generation adds formatting and styles settings. The generator supports line-based or minified markup and no, embedded, or inline CSS. Page generation, manifest values, validation, tests, and documentation now cover these choices.

Changes: HTML output options

Layer / File(s)	Summary
Settings and markup spellings `internal/format/htmlfile/settings.go`, `internal/format/htmlfile/markup.go`, `README.md`, `CHANGELOG.md`, `internal/gui/text/locale/{registry,said}/*.json`	HTML settings now accept `formatting=lines` or `minified`, and `styles=none`, `embedded`, or `inline`. The generator prepares markup spellings for each combination. Documentation and locale entries describe the settings and updated picture placement.
Page and picture generation `internal/format/htmlfile/html.go`, `internal/format/htmlfile/page.go`, `internal/format/htmlfile/blocks.go`, `internal/format/htmlfile/catalogue.go`, `internal/format/htmlfile/characters.go`, `internal/format/htmlfile/pictures.go`	Page elements and pictures use the selected markup. Minified pages report no line ending. Picture markup and byte counts include the selected opening and closing fragments.
Output validation and tests `internal/oracle/strict.py`, `internal/guard/*`, `internal/guard/testdata/generator-golden.json`	Validation checks line layout and CSS placement. Guard tests cover formatting and style combinations, catalogue text, manifest values, and golden output sizes.

Merge Risk: 🔵 Low · up to 82621

The structural check can accept pages whose line endings or CSS do not match the selected settings. These validation gaps are narrow and do not prevent normal page generation; they warrant a fix or explicit acceptance before merging.

Review comments at @internal/oracle/strict.py:
- Around line 869-870: Update the formatting=lines structural check to reject
carriage returns in the page text, including when characters=international,
while preserving its existing requirements for a trailing LF and at least two
line breaks.
- Around line 923-926: Update the styles=embedded validation around HTML_STYLED
to reject rules with empty or whitespace-only bodies, and update the
styles=inline check for tags and bare to reject empty or whitespace-only style
attributes. Add mutations covering both cases in the lines and minified modes.
