.\" 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 NAME
mkdoc \- Extracts and optionally converts Markdown comments in source code to HTML
.SH SYNOPSIS
package require \fBTcl 8\&.6 9\fR
.sp
package require \fBMarkdown ?1\&.2\&.2?\fR
.sp
package require \fByaml ?0\&.4\&.2?\fR
.sp
package require \fBmkdoc ?0\&.7\&.2?\fR
.sp
package require \fBhook\fR
.sp
\fB::mkdoc::mkdoc\fR \fIinfile\fR \fIoutfile\fR ?\fB-css\fR \fIcssfile\fR?
.sp
\fB::mkdoc::run\fR \fIinfile\fR
.sp
.BE
.SH DESCRIPTION
The package \fBmkdoc\fR provides a command to extract documentation embedded in code
and optionally convert these comments into HTML\&.
The latter uses Tcllib's \fBMarkdown\fR package\&.
Each line of the embedded documentation begins with the special comment marker
\fB#'\fR\&.
.TP
\fB::mkdoc::mkdoc\fR \fIinfile\fR \fIoutfile\fR ?\fB-css\fR \fIcssfile\fR?
The command reads the specified \fIinfile\fR and extracts the code comments introduced by
the \fB #'\fR marker\&.  If the \fIoutfile\fR is either a "\fI\&.html\fR" or "\fI\&.htm\fR"
file the Markdown is converted into HTML using either a default style or the specified
style sheet \fIcssfile\fR\&.
.sp
All arguments are paths to the files to read from or write to\&.
.sp
The result of the command is the empty string\&.
.sp
See section \fBFormatting\fR for the supported Markdown syntax and extensions
to it\&.
.TP
\fB::mkdoc::run\fR \fIinfile\fR
The command reads the specified \fIinfile\fR, extracts the embedded documentation, and
then executes the contents of the first example, i\&.e\&. \fB```\fR-quoted block, found in
the \fBExample\fR section\&.
.sp
Here is such an example which will be executed by the Tcl interpreter
.CS


    #' ## <a name="example">Example</a>
    #'
    #' ```
    #' puts "Hello mkdoc package"
    #' puts "I am in the example section"
    #' ```

.CE
.sp
\fIDANGER, BEWARE\fR\&.
Failing to open the \fIinfile\fR causes the command to \fIexit\fR the entire process\&.
.sp
Use of this command in a general context is not recommended\&.
.PP
.SH EXAMPLES
The example below demonstrates the conversion of the documentation embedded into the file
"\fImkdoc\&.tcl\fR" itself:
.PP
.CS


    package require mkdoc
    # extracting the Markdown
    mkdoc::mkdoc mkdoc\&.tcl mkdoc\&.md
    # converting Markdown to HTML
    mkdoc::mkdoc mkdoc\&.md mkdoc\&.html
    # direct conversion without intermediate file
    mkdoc::mkdoc mkdoc\&.tcl mkdoc\&.html

.CE
.SH FORMATTING
The package supports the syntax supported by Tcllib's \fBMarkdown\fR package\&.
.PP
It further supports a set of simple YAML headers whose information is inserted into
appropriate HTML \fBmeta\fR-tags\&. The supported keys are
.TP
\fBauthor\fR
Set the document author\&. Defaults to \fBNN\fR\&.
.TP
\fBtitle\fR
Set the document title\&. Defaults to \fBDocumentation \fR\fBfilename\fR]\&.
.TP
\fBdate\fR
Sets the document date\&. Defaults to the current day\&.
.TP
\fBcss\fR
Sets a custom CSS stylesheet\&. Defaults to the internal mkdoc sheet\&.
.PP
.PP
\fINote\fR that in Markdown output mode these headers are simply passed through
into the result\&. This is proper, as processors like \fBpandoc\fR are able to use them
as well\&.
.PP
See the example below for the syntax:
.CS


    #' ---
    #' title: mkdoc::mkdoc 0\&.7\&.1
    #' author: Detlef Groth, Schwielowsee, Germany
    #' date: 2022-04-17
    #' css: mini\&.css
    #' ---
    #'

.CE
.PP
Another extension over standard Markdown is the support of a single level of includes\&.
.PP
See the example below for the syntax:
.CS


    #' #include "path/to/include/file"

.CE
.PP
\fINote\fR, the double-quotes around the path are part of the syntax\&.
.PP
\fIBeware\fR further that relative paths are resolved relative to the current
working directory, and \fInot\fR relative to the location of the including file\&.
