.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH DESCRIPTION
The package \fBMarkdown\fR provides a command to convert
Markdown annotated text into HMTL\&.
.TP
\fB::Markdown::convert\fR \fImarkdown\fR
This command takes in a block of Markdown text, and returns a block
of HTML\&.
.sp
The converter supports two types of syntax highlighting for
fenced code blocks: highlighting via a registered converter
(see \fB::Markdown::register\fR), or pure JavaScript highlighting,
e\&.g\&. via "highlight\&.js", where the language specifier used in the
markup is set as CSS class of the "code" element in the returned markup\&.
.TP
\fB::Markdown::register\fR \fIlangspec\fR \fIconverter\fR
Register a language specific converter for prettifying a code block
(e\&.g\&. syntax highlighting)\&.  Markdown supports fenced code blocks with
an optional language specifier (e\&.g\&. "tcl")\&. When the markdown parser
processes such a code block and a converter for the specified langspec
is registered, the converter is called with the raw code block as
argument\&. The converter is supposed to return the markup of the code
block as result\&. The specified converter can be an arbitrary Tcl
command, the raw text block is added as last argument upon invocation\&.
.TP
\fB::Markdown::get_lang_counter\fR
Return a dict of language specifier and number of occurrences in
fenced code blocks\&. This function can be used e\&.g\&. to detect, whether
some CSS or JavaScript headers should be included for rendering
without the need of postprocessing the rendered result\&.
.TP
\fB::Markdown::reset_lang_counter\fR
Reset the language counters\&.
.PP
.SH "BUGS, IDEAS, FEEDBACK"
This document, and the package it describes, will undoubtedly contain
bugs and other problems\&.
Please report such in the category \fItextutil\fR of the
\fITcllib Trackers\fR [http://core\&.tcl\&.tk/tcllib/reportlist]\&.
Please also report any ideas for enhancements you may have for either
package and/or documentation\&.
.PP
When proposing code changes, please provide \fIunified diffs\fR,
i\&.e the output of \fBdiff -u\fR\&.
.PP
Note further that \fIattachments\fR are strongly preferred over
inlined patches\&. Attachments can be made by going to the \fBEdit\fR
form of the ticket immediately after its creation, and then using the
left-most button in the secondary navigation bar\&.
