Generating HTML¶
To generate highlighted, hyperlinked web pages from source code, run the following command in a shell:
$ agda --html --html-dir={output directory} {root module}
You can change the way in which the code is highlighted by providing
your own CSS file instead of the default, included one (use the --css option).
Note
The Agda.css shipped with Agda is located at
${AGDA_DIR}/html/Agda.css. Since version 2.6.2, the
AGDA_DIR is printed by option --print-agda-dir.
Thus, you can get hold of the CSS file via
cat $(agda --print-agda-dir)/html/Agda.css.
You can also highlight all the occurrences of the symbol your mouse is
hovering in the HTML by adding the --highlight-occurrences option.
The default behaviour only highlight the single symbol your mouse is
hovering. Note that this feature may cause browser performance problem,
please enable it carefully (not recommended for huge files).
If you’re using Literate Agda with Markdown or reStructedText and you
want to highlight your Agda codes with Agda’s HTML backend and render
the rest of the content (let’s call it “literate” part for convenience)
with some another renderer, you can use the --html-highlight=code
option, which makes the Agda compiler:
- not wrapping the literate part into
<a class="Background">tags - not wrapping the generated document with a
<html>tag, which means you’ll have to specify the CSS location somewhere else, like<link rel="stylesheet" type="text/css" href="Agda.css"> - converting
<a class="Markup">tags into<pre class="agda-code">tags that wrap the complete Agda code block below - generating files with extension as-is (i.e. .lagda.md becomes .md, .lagda.rst becomes .rst)
- for reStructuredText, a
.. raw:: htmlwill be inserted before every code blocks
This will affect all the files involved in one compilation, making
pure Agda code files rendered without HTML footer/header as well.
To use code with literate Agda files and all with pure Agda
files, use --html-highlight=auto, which means auto-detection.
