Release v0.81.1 · Pipelex/pipelex

[v0.81.1] - 2026-10-10

Formatted Markdown for document engines, and a markdown filter for plain-data templates: the document engine contract gains format_markdown in pipelex.cogt.doc_gen.formatted_markdown, which reads a Markdown text by the rules the built-in PDF engine prints it by and returns a FormattedMarkdown, plain data of paragraphs, headings, list items with their marker and the paragraph or heading they open with, code blocks, rules and tables whose cells carry their column's alignment, every block with the list depth and the quote depth it sits at and holding text spans with their bold, italic, strikethrough, code and link, whose str() is its plain text and which is false when the text formats into nothing, so an engine prints Markdown formatted in its own format. make_plain_data_template_environment() registers a markdown filter that returns one, {{ invoice.notes | markdown }}, which is false for an empty or a blank text, so {% set notes = invoice.notes | markdown %}{% if notes %}…{{ notes }}…{% endif %} converts the text once to test and print it, and takes an optional finalize through which an engine prints it, a value printing its plain text without one. Inside a template render the conversion is charged to the render's budget; called from an engine's own code it spends from a budget of its own, as large as one render's, and an overdraft raises MarkdownFormattingBudgetError.

A PDF of deeply nested emphasis prints: the built-in PDF engine no longer fails with a RecursionError on a Markdown text whose emphasis nests hundreds deep, such as four hundred *a before a word and four hundred c* after it; inline markup nested past fifty levels is dropped and its text printed.
