haredoc(5) File Formats Manual haredoc(5) NAME haredoc - Hare documentation format DESCRIPTION Hare documentation is written in a simple markup language. By default, haredoc(1) will display the documentation literally, without any additional formatting. Other tools may format Hare documentation into other formats. Text may be written normally, broken into several lines to conform to the 80-column limit. To begin a new paragraph, insert an empty line. References to other declarations and modules may be written in brackets, like this: [[os::stdout]]. References to modules should include a trailing :: in the identifier: [[os::exec::]]. A bulleted list can be started by opening a line with "-", optionally pre- ceded by a space. Each line opened like this begins a new list item. To complete the list, insert an empty line. Code samples may be used by starting a line with a single tab, optionally preceded by a space. This markup language is extracted from Hare comments preceding exported symbols in your source code, and from a file named "README" in your module directory, if present. README A file named "README" at the root directory of a Hare module is used as a summary of the entire module. It should start with a brief one-line summary of the module using the module's name (the last item in its identifier), a colon, a space, and a summary, as follows: memio: memory-backed I/O functions This may be followed by an empty line, then a long-form summary of the mod- ule using the documentation format described abovce. EXAMPLE // Foos the bars. See also [[foobar]]. // // If you instead want to bar the foos, use one of the functions in // [[bar::foo::]]. // // - First, the bars are obtained. // - They are then fooed. // - Finally, the result is returned. // // let x = example(); // assert(x == 0); export fn example() int = 0; NOTES It's expected that tools which parse documentation for the purpose of con- verting it into another format will perform additional processing to decou- ple the content from its original textual representation: * Line breaks within a paragraph or list item should be ignored. * Repeated whitespace outside of a code sample should be collapsed. * Multiple code samples separated by empty lines should be collapsed into one code sample, so the empty lines are moved into the code sample it- self. hare::parse::doc:: in the standard library handles all of this processing for you. Parsers are permitted (and encouraged) to error out on invalid input, such as a malformed or unterminated [[reference]]. SEE ALSO haredoc(1) 2026-08-27 haredoc(5)
