MARKDOWN(1)

NAME
discount - text to html conversion tool

SYNOPSIS
discount [-d] [-T] [-V] [-b url-base] [-C prefix] [-F bitmap] [-f flags] [-n] [-o file] [-S] [-s text] [-t text] [-toc] [textfile]

DESCRIPTION
The discount utility reads the markdown(7)-formatted textfile (or stdin if not specified,) compiles it, and writes the html output to stdout.

The options are as follows:

-b url-base
    Links in source beginning with / will be prefixed with url-base in the output.

-C  When processing markdown extra-style footnotes, use the given prefix instead of the default of fn.

-d  Instead of writing the html file, dump a parse tree to stdout.

-f flags
    Set or clear various translation flags. The flags are in a comma-delimited list, with an optional + (enable), - (disable), or no (disable) lprefix on each flag.

    links
        Allow links.

    image
        Allow images.

    smarty
        Enable smartypants.

    pants
        Enable smartypants.

    html
        Allow raw html.

    strict
        Disable superscript, strikethrough & relaxed emphasis.

    ext Enable pseudo-protocols.

    cdata
        Generate code for xml ![CDATA[...]].

    1.0 Compatibility with MarkdownTest_1.0

    autolink
        Make http://foo.com a link even without <>.

    safelink
        Paranoid check for link protocol.

    header
        Process pandoc-style header blocks.

    tabstop
        Expand tabs to 4 spaces.

    divquote
        Allow >%class% blocks.

    alphalist
        Allow alphabetic lists.

    definitionlist
        Allow definition lists at all (default). Use dldiscount and dlextra to control which syntaxes are respected.

    dldiscount
        Enable discount-style definition lists (default).

    dlextra
        Enable extra-style definition lists (not default). Both styles may be enabled simultaneously.

    footnote
        Allow markdown extra-style footnotes.

    style
        Extract <style> blocks from the output.

    fencedcode
        Allow fenced code blocks (not default).

    idanchor
        Use id= anchors for table-of-contents links instead of <a name=/> (not default).

    githubtags
        Allow underscore and dash in passed through element names (not default).

    urlencodedanchor
        Use url-encoded chars for multibyte and nonalphanumeric chars rather than dots in toc links.

    As an example, the option -f nolinks,smarty tells discount to not allow <a tags, and to do smarty pants processing.

-F bitmap
    Set translation flags. Bitmap is a bit map of the various configuration options described in markdown(3) (the flag values are defined in mkdio.h)

-n  Don't write generated html.

-o file
    Write the generated html to file.

-S  output <style> blocks.

-V  Show the version# and compile-time configuration data.

    If the version includes the string DEBUG, discount was configured with memory allocation debugging.

    If the version includes the string TAB, discount was configured to use the specified tabstop.

-VV Show the version#, the compile-time configuration, and the run-time configuration.

-t text
    Use mkd_text(3) to format text instead of processing stdin with the markdown(3) function.

-T  If run with the table-of-content flag on, dump the table of contents before the formatted text.

-s text
    Use the markdown(3) function to format text.

-toc
    Set the table-of-content flag, then dump the table of contents before the formatted text (a shorthand for --T --toc )

RETURN VALUES
The discount utility exits 0 on success, and >0 if an error occurs.
