This command creates a new docidx object with an associated Tcl command whose name is \fIobjectName\fR\&. This \fIobject\fR command is explained in full detail in the sections \fBOBJECT COMMAND\fR and \fBOBJECT METHODS\fR\&. The object command will be created under the current namespace if the \fIobjectName\fR is not fully qualified, and in the specified namespace otherwise\&. .sp The options and their values coming after the name of the object are used to set the initial configuration of the object\&. .TP \fB::doctools::idx::help\fR This is a convenience command for applications wishing to provide their user with a short description of the available formatting commands and their meanings\&. It returns a string containing a standard help text\&. .TP \fB::doctools::idx::search\fR \fIpath\fR Whenever an object created by this the package has to map the name of a format to the file containing the code for its formatting engine it will search for the file in a number of directories stored in a list\&. See section \fBFORMAT MAPPING\fR for more explanations\&. .sp This list not only contains three default directories which are declared by the package itself, but is also extensible user of the package\&. This command is the means to do so\&. When given a \fIpath\fR to an existing and readable directory it will prepend that directory to the list of directories to search\&. This means that the \fIpath\fR added last is later searched through first\&. .sp An error will be thrown if the \fIpath\fR either does not exist, is not a directory, or is not readable\&. .PP .SS "OBJECT COMMAND" All commands created by \fB::doctools::idx::new\fR have the following general form and may be used to invoke various operations on their docidx converter object\&. .TP \fBobjectName\fR \fBmethod\fR ?\fIarg arg \&.\&.\&.\fR? The method \fBmethod\fR and its \fIarg\fR'uments determine the exact behavior of the command\&. See section \fBOBJECT METHODS\fR for the detailed specifications\&. .PP .SS "OBJECT METHODS" .TP \fIobjectName\fR \fBconfigure\fR The method returns a list of all known options and their current values when called without any arguments\&. .TP \fIobjectName\fR \fBconfigure\fR \fIoption\fR The method behaves like the method \fBcget\fR when called with a single argument and returns the value of the option specified by said argument\&. .TP \fIobjectName\fR \fBconfigure\fR \fB-option\fR \fIvalue\fR\&.\&.\&. The method reconfigures the specified \fBoption\fRs of the object, setting them to the associated \fIvalue\fRs, when called with an even number of arguments, at least two\&. .sp The legal options are described in the section \fBOBJECT CONFIGURATION\fR\&. .TP \fIobjectName\fR \fBcget\fR \fB-option\fR This method expects a legal configuration option as argument and will return the current value of that option for the object the method was invoked for\&. .sp The legal configuration options are described in section \fBOBJECT CONFIGURATION\fR\&. .TP \fIobjectName\fR \fBdestroy\fR This method destroys the object it is invoked for\&. .TP \fIobjectName\fR \fBformat\fR \fItext\fR This method runs the \fItext\fR through the configured formatting engine and returns the generated string as its result\&. An error will be thrown if no \fB-format\fR was configured for the object\&. .sp The method assumes that the \fItext\fR is in \fIdocidx\fR format as specified in the companion document \fIdocidx_fmt\fR\&. Errors will be thrown otherwise\&. .TP \fIobjectName\fR \fBmap\fR \fIsymbolic\fR \fIactual\fR This methods add one entry to the per-object mapping from \fIsymbolic\fR filenames to the \fIactual\fR uris\&. The object just stores this mapping and makes it available to the configured formatting engine through the command \fBdt_fmap\fR\&. This command is described in more detail in the \fIdocidx plugin API reference\fR which specifies the interaction between the objects created by this package and index formatting engines\&. .TP \fIobjectName\fR \fBparameters\fR This method returns a list containing the names of all engine parameters provided by the configured formatting engine\&. It will return an empty list if the object is not yet configured for a specific format\&. .TP \fIobjectName\fR \fBsearch\fR \fIpath\fR This method extends the per-object list of paths searched for index formatting engines\&. See also the command \fB::doctools::idx::search\fR on how to extend the per-package list of paths\&. Note that the path entered last will be searched first\&. For more details see section \fBFORMAT MAPPING\fR\&. .TP \fIobjectName\fR \fBsetparam\fR \fIname\fR \fIvalue\fR This method sets the \fIname\fRd engine parameter to the specified \fIvalue\fR\&. It will throw an error if the object is either not yet configured for a specific format, or if the formatting engine for the configured format does not provide a parameter with the given \fIname\fR\&. The list of parameters provided by the configured formatting engine can be retrieved through the method \fBparameters\fR\&. .TP \fIobjectName\fR \fBwarnings\fR This method returns a list containing all the warnings which were generated by the configured formatting engine during the last invocation of the method \fBformat\fR\&. .PP .SS "OBJECT CONFIGURATION" All docidx objects understand the following configuration options: .TP \fB-file\fR \fIfile\fR The argument of this option is stored in the object and made available to the configured formatting engine through the command \fBdt_file\fR\&. This command is described in more detail in the companion document \fIdocidx_api\fR which specifies the API between the object and formatting engines\&. .sp The default value of this option is the empty string\&. .sp The configured formatting engine should interpret the value as the name of the file containing the document which is currently processed\&. .TP \fB-format\fR \fItext\fR The argument of this option specifies the format to generate and by implication the formatting engine to use when converting text via the method \fBformat\fR\&. Its default value is the empty string\&. The method \fBformat\fR cannot be used if this option is not set to a valid value at least once\&. .sp The package will immediately try to map the given name to a file containing the code for a formatting engine generating that format\&. An error will be thrown if this mapping fails\&. In that case a previously configured format is left untouched\&. .sp The section \fBFORMAT MAPPING\fR explains in detail how the package and object will look for engine implementations\&. .PP .SS "FORMAT MAPPING" The package and object will perform the following algorithm when trying to map a format name \fIfoo\fR to a file containing an implementation of a formatting engine for \fIfoo\fR: .IP [1] If \fIfoo\fR is the name of an existing file then this file is directly taken as the implementation\&. .IP [2] If not, the list of per-object search paths is searched\&. For each directory in the list the package checks if that directory contains a file "\fIidx\&.\fIfoo\fR\fR"\&. If yes, then that file is taken as the implementation\&. .sp Note that this list of paths is initially empty and can be extended through the object method \fBsearch\fR\&. .IP [3] If not, the list of package paths is searched\&. For each directory in the list the package checks if that directory contains a file "\fIidx\&.\fIfoo\fR\fR"\&. If yes, then that file is taken as the implementation\&. .sp This list of paths can be extended through the command \fB::doctools::idx::search\fR\&. It contains initially one path, the subdirectory "\fImpformats\fR" of the directory the package itself is located in\&. In other words, if the package implementation "\fIdocidx\&.tcl\fR" is installed in the directory "\fI/usr/local/lib/tcllib/doctools\fR" then it will by default search the directory "\fI/usr/local/lib/tcllib/doctools/mpformats\fR" for format implementations\&. .IP [4] The mapping fails\&. .PP .SH "PREDEFINED ENGINES" The package provides predefined formatting engines for the following formats\&. Some of the formatting engines support engine parameters\&. These will be explicitly highlighted\&. .TP html This engine generates HTML markup, for processing by web browsers and the like\&. This engine supports three parameters: .RS .TP footer The value for this parameter has to be valid selfcontained HTML markup for the body section of a HTML document\&. The default value is the empty string\&. The value is inserted into the generated output just before the \fB\fR tag, closing the body of the generated HTML\&. .sp This can be used to insert boilerplate footer markup into the generated document\&. .TP header The value for this parameter has to be valid selfcontained HTML markup for the body section of a HTML document\&. The default value is the empty string\&. The value is inserted into the generated output just after the \fB\fR tag, starting the body of the generated HTML\&. .sp This can be used to insert boilerplate header markup into the generated document\&. .TP meta The value for this parameter has to be valid selfcontained HTML markup for the header section of a HTML document\&. The default value is the empty string\&. The value is inserted into the generated output just after the \fB\fR tag, starting the header section of the generated HTML\&. .sp This can be used to insert boilerplate meta data markup into the generated document, like references to a stylesheet, standard meta keywords, etc\&. .RE .sp .TP latex This engine generates output suitable for the \fBlatex\fR text processor coming out of the TeX world\&. .TP list This engine retrieves version, section and title of the manpage from the document\&. As such it can be used to generate a directory listing for a set of manpages\&. .TP markdown This engine generates \fIMarkdown\fR markup\&. .TP nroff This engine generates nroff output, for processing by \fBnroff\fR, or \fBgroff\fR\&. The result will be standard man pages as they are known in the unix world\&. .TP null This engine generates no outout at all\&. This can be used if one just wants to validate some input\&. .TP tmml This engine generates TMML markup as specified by Joe English\&. The Tcl Manpage Markup Language is a derivate of XML\&. .TP wiki This engine generates Wiki markup as understood by Jean Claude Wippler's \fBwikit\fR application\&. .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 \fIdoctools\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\&. .SH "SEE ALSO" docidx_intro, docidx_lang_cmdref, docidx_lang_intro, docidx_lang_syntax, docidx_plugin_apiref .SH KEYWORDS HTML, TMML, conversion, docidx, documentation, index, keyword index, latex, manpage, markdown, markup, nroff, wiki .SH CATEGORY Documentation tools .SH COPYRIGHT .nf Copyright (c) 2003-2019 Andreas Kupries .fi
