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 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. .\" .\" # Set up traps and other miscellaneous stuff for Tcl/Tk man pages. .if t .wh -1.3i ^B .nr ^l \n(.l .ad b .\" # Start an argument description .de AP .ie !"\\$4"" .TP \\$4 .el \{\ . ie !"\\$2"" .TP \\n()Cu . el .TP 15 .\} .ta \\n()Au \\n()Bu .ie !"\\$3"" \{\ \&\\$1 \\fI\\$2\\fP (\\$3) .\".b .\} .el \{\ .br .ie !"\\$2"" \{\ \&\\$1 \\fI\\$2\\fP .\} .el \{\ \&\\fI\\$1\\fP .\} .\} .. .\" # define tabbing values for .AP .de AS .nr )A 10n .if !"\\$1"" .nr )A \\w'\\$1'u+3n .nr )B \\n()Au+15n .\" .if !"\\$2"" .nr )B \\w'\\$2'u+\\n()Au+3n .nr )C \\n()Bu+\\w'(in/out)'u+2n .. .AS Tcl_Interp Tcl_CreateInterp in/out .\" # BS - start boxed text .\" # ^y = starting y location .\" # ^b = 1 .de BS .br .mk ^y .nr ^b 1u .if n .nf .if n .ti 0 .if n \l'\\n(.lu\(ul' .if n .fi .. .\" # BE - end boxed text (draw box now) .de BE .nf .ti 0 .mk ^t .ie n \l'\\n(^lu\(ul' .el \{\ .\" Draw four-sided box normally, but don't draw top of .\" box if the box started on an earlier page. .ie !\\n(^b-1 \{\ \h'-1.5n'\L'|\\n(^yu-1v'\l'\\n(^lu+3n\(ul'\L'\\n(^tu+1v-\\n(^yu'\l'|0u-1.5n\(ul' .\} .el \}\ \h'-1.5n'\L'|\\n(^yu-1v'\h'\\n(^lu+3n'\L'\\n(^tu+1v-\\n(^yu'\l'|0u-1.5n\(ul' .\} .\} .fi .br .nr ^b 0 .. .\" # VS - start vertical sidebar .\" # ^Y = starting y location .\" # ^v = 1 (for troff; for nroff this doesn't matter) .de VS .if !"\\$2"" .br .mk ^Y .ie n 'mc \s12\(br\s0 .el .nr ^v 1u .. .\" # VE - end of vertical sidebar .de VE .ie n 'mc .el \{\ .ev 2 .nf .ti 0 .mk ^t \h'|\\n(^lu+3n'\L'|\\n(^Yu-1v\(bv'\v'\\n(^tu+1v-\\n(^Yu'\h'-|\\n(^lu+3n' .sp -1 .fi .ev .\} .nr ^v 0 .. .\" # Special macro to handle page bottom: finish off current .\" # box/sidebar if in box/sidebar mode, then invoked standard .\" # page bottom macro. .de ^B .ev 2 'ti 0 'nf .mk ^t .if \\n(^b \{\ .\" Draw three-sided box if this is the box's first page, .\" draw two sides but no top otherwise. .ie !\\n(^b-1 \h'-1.5n'\L'|\\n(^yu-1v'\l'\\n(^lu+3n\(ul'\L'\\n(^tu+1v-\\n(^yu'\h'|0u'\c .el \h'-1.5n'\L'|\\n(^yu-1v'\h'\\n(^lu+3n'\L'\\n(^tu+1v-\\n(^yu'\h'|0u'\c .\} .if \\n(^v \{\ .nr ^x \\n(^tu+1v-\\n(^Yu \kx\h'-\\nxu'\h'|\\n(^lu+3n'\ky\L'-\\n(^xu'\v'\\n(^xu'\h'|0u'\c .\} .bp 'fi .ev .if \\n(^b \{\ .mk ^y .nr ^b 2 .\} .if \\n(^v \{\ .mk ^Y .\} .. .\" # DS - begin display .de DS .RS .nf .sp .. .\" # DE - end display .de DE .fi .RE .sp .. .\" # SO - start of list of standard options .de SO 'ie '\\$1'' .ds So \\fBoptions\\fR 'el .ds So \\fB\\$1\\fR .SH "STANDARD OPTIONS" .LP .nf .ta 5.5c 11c .ft B .. .\" # SE - end of list of standard options .de SE .fi .ft R .LP See the \\*(So manual entry for details on the standard options. .. .\" # OP - start of full description for a single option .de OP .LP .nf .ta 4c Command-Line Name: \\fB\\$1\\fR Database Name: \\fB\\$2\\fR Database Class: \\fB\\$3\\fR .fi .IP .. .\" # CS - begin code excerpt .de CS .RS .nf .ta .25i .5i .75i 1i .. .\" # CE - end code excerpt .de CE .fi .RE .. .\" # UL - underline word .de UL \\$1\l'|0\(ul'\\$2 .. .\" # QW - apply quotation marks to word .de QW .ie '\\*(lq'"' ``\\$1''\\$2 .\"" fix emacs highlighting .el \\*(lq\\$1\\*(rq\\$2 .. .\" # PQ - apply parens and quotation marks to word .de PQ .ie '\\*(lq'"' (``\\$1''\\$2)\\$3 .\"" fix emacs highlighting .el (\\*(lq\\$1\\*(rq\\$2)\\$3 .. .\" # QR - quoted range .de QR .ie '\\*(lq'"' ``\\$1''\\-``\\$2''\\$3 .\"" fix emacs highlighting .el \\*(lq\\$1\\*(rq\\-\\*(lq\\$2\\*(rq\\$3 .. .\" # MT - "empty" string .de MT .QW "" .. .BS .SH NAME mkdoc \- Extracts and optionally converts Markdown comments in source code to HTML .SH SYNOPSIS package require \fBTcl 8\&.6\fR .sp package require \fBMarkdown ?1\&.2\&.1?\fR .sp package require \fByaml ?0\&.4\&.1?\fR .sp package require \fBmkdoc ?0\&.7\&.0?\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 #' ## Example #' #' ``` #' 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\&.0 #' 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\&. .SH "BUGS, IDEAS, FEEDBACK" This document, and the package it describes, will undoubtedly contain bugs and other problems\&.
