D.1 LaTeXML::Common::Config

Configuration logic for LaTeXML

SYNPOSIS

    use LaTeXML::Common::Config;
    my $config = LaTeXML::Common::Config->new(
              profile=>'name',
              timeout=>60,
              ... );
    $config->read(\@ARGV);
    $config->check;
    my $value = $config->get($name);
    $config->set($name,$value);
    $config->delete($name);
    my $bool = $config->exists($name);
    my @keys = $config->keys;
    my $options_hashref = $config->options;
    my $config_clone = $config->clone;

Description

Configuration management class for LaTeXML options. * Responsible for defining the options interface and parsing the usual Perl command-line options syntax * Provides the intuitive getters, setters, as well as hash methods for manipulating the option values. * Also supports cloning into new configuration objects.

Methods

my $config = LaTeXML::Common::Config->new(%options);

Creates a new configuration object. Note that you should try not to provide your own %options hash but rather create an empty configuration and use $config->read to read in the options.

$config->read(\@ARGV);

This is the main method for parsing in LaTeXML options. The input array should either be @ARGV, e.g. when the options were provided from the command line using the classic Getopt::Long syntax, or any other array reference that conforms to that setup.

$config->check;

Ensures that the configuration obeys the given profile and performs a set of assignments of meaningful defaults (when needed) and normalizations (for relative paths, etc).

my $value = $config->get($name);

Classic getter for the $value of an option $name.

$config->set($name,$value);

Classic setter for the $value of an option $name.

$config->delete($name);

Deletes option $name from the configuration.

my $bool = $config->exists($name);

Checks whether the key $name exists in the options hash of the configuration. Similarly to Perl’s ”exist” for hashes, it returns true even when the option’s value is undefined.

my @keys = $config->keys;

Similar to ”keys %hash” in Perl. Returns an array of all option names.

my $options_hashref = $config->options;

Returns the actual hash reference that holds all options within the configuration object.

my $config_clone = $config->clone;

Clones $config into a new LaTeXML::Common::Config object, $config_clone.

Options & Arguments

General Options

--verbose

Increases the verbosity of output during processing, used twice is pretty chatty. Can be useful for getting more details when errors occur.

--quiet

Reduces the verbosity of output during processing, used twice is pretty silent.

--VERSION

Shows the version number of the LaTeXML package..

--debug=package

Enables debugging output for the named package. The package is given without the leading LaTeXML::.

--base=dir

Sepcifies the base working directory for the conversion server. Useful when converting sets of documents that use relative paths.

--log=file

Specifies the log file; be default any conversion messages are printed to STDERR.

--help

Shows this help message.

Source Options

--destination=file

Specifies the destination file; by default the XML is written to STDOUT.

--preload=module

Requests the loading of an optional module or package. This may be useful if the TeX code does not specificly require the module (eg. through input or usepackage). For example, use --preload=LaTeX.pool to force LaTeX mode.

--preamble=file

Requests the loading of a tex file with document frontmatter, to be read in before the converted document, but after all –preload entries.

Note that the given file MUST contain \begin{document} or an equivalent environment start, when processing LaTeX documents.

If the file does not contain content to appear in the final document, but only macro definitions and setting of internal counters, it is more appropriate to use –preload instead.

--postamble=file

Requests the loading of a tex file with document backmatter, to be read in after the converted document.

Note that the given file MUST contain \end{document} or an equivalent environment end, when processing LaTeX documents.

--sourcedirectory=source

Specifies the directory where the original latex source is located. Unless LaTeXML is run from that directory, or it can be determined from the xml filename, it may be necessary to specify this option in order to find graphics and style files.

--path=dir

Add dir to the search paths used when searching for files, modules, style files, etc; somewhat like TEXINPUTS. This option can be repeated.

--validate, --novalidate

Enables (or disables) the validation of the source XML document (the default).

--bibtex

Forces latexml to treat the file as a BibTeX bibliography. Note that the timing is slightly different than the usual case with BibTeX and LaTeX. In the latter case, BibTeX simply selects and formats a subset of the bibliographic entries; the actual TeX expansion is carried out when the result is included in a LaTeX document. In contrast, latexml processes and expands the entire bibliography; the selection of entries is done during post-processing. This also means that any packages that define macros used in the bibliography must be specified using the --preload option.

--inputencoding=encoding

Specify the input encoding, eg. --inputencoding=iso-8859-1. The encoding must be one known to Perl’s Encode package. Note that this only enables the translation of the input bytes to UTF-8 used internally by LaTeXML, but does not affect catcodes. In such cases, you should be using the inputenc package. Note also that this does not affect the output encoding, which is always UTF-8.

TeX Conversion Options

--includestyles

This optional allows processing of style files (files with extensions sty, cls, clo, cnf). By default, these files are ignored unless a latexml implementation of them is found (with an extension of ltxml).

These style files generally fall into two classes: Those that merely affect document style are ignorable in the XML. Others define new markup and document structure, often using deeper LaTeX macros to achieve their ends. Although the omission will lead to other errors (missing macro definitions), it is unlikely that processing the TeX code in the style file will lead to a correct document.

--timeout=secs

Set time cap for conversion jobs, in seconds. Any job failing to convert in the time range would return with a Fatal error of timing out. Default value is 600, set to 0 to disable.

--nocomments

Normally latexml preserves comments from the source file, and adds a comment every 25 lines as an aid in tracking the source. The option –nocomments discards such comments.

--documentid=id

Assigns an ID to the root element of the XML document. This ID is generally inherited as the prefix of ID’s on all other elements within the document. This is useful when constructing a site of multiple documents so that all nodes have unique IDs.

--strict

Specifies a strict processing mode. By default, undefined control sequences and invalid document constructs (that violate the DTD) give warning messages, but attempt to continue processing. Using --strict makes them generate fatal errors.

--post

Request post-processing, auto-enabled by any requested post-processor. Disabled by default. If post-processing is enabled, the graphics and cross-referencing processors are on by default.

Format Options

--format=(html|html5|html4|xhtml|xml|epub)

Specifies the output format for post processing. By default, it will be guessed from the file extension of the destination (if given), with html implying html5, xhtml implying xhtml and the default being xml, which you probably don’t want.

The html5 format converts the material to html5 form with mathematics as MathML; html5 supports SVG. html4 format converts the material to the earlier html form, version 4, and the mathematics to png images. xhtml format converts to xhtml and uses presentation MathML (after attempting to parse the mathematics) for representing the math. html5 similarly converts math to presentation MathML. In these cases, any graphics will be converted to web-friendly formats and/or copied to the destination directory. If you simply specify html, it will treat that as html5.

For the default, xml, the output is left in LaTeXML’s internal xml, but the math is parsed and converted to presentation MathML. For html, html5 and xhtml, a default stylesheet is provided, but see the --stylesheet option.

--xml

Requests XML output; this is the default. DEPRECATED: use –format=xml instead

--tex

Requests TeX output for debugging purposes; processing is only carried out through expansion and digestion. This may not be quite valid TeX, since Unicode may be introduced.

--box

Requests Box output for debugging purposes; processing is carried out through expansion and digestions, and the result is printed.

--profile

Variety of shorthand profiles. Note that the profiles come with a variety of preset options. You can examine any of them in their resources/Profiles/name.opt file.

Example: latexmlc --profile=math '1+2=3'

--omitdoctype, --noomitdoctype

Omits (or includes) the document type declaration. The default is to include it if the document model was based on a DTD.

--numbersections, --nonumbersections

Includes (default), or disables the inclusion of section, equation, etc, numbers in the formatted document and crossreference links.

--stylesheet=xslfile

Requests the XSL transformation of the document using the given xslfile as stylesheet. If the stylesheet is omitted, a ‘standard’ one appropriate for the format (html4, html5 or xhtml) will be used.

--css=cssfile

Adds cssfile as a css stylesheet to be used in the transformed html/html5/xhtml. Multiple stylesheets can be used; they are included in the html in the order given, following the default ltx-LaTeXML.css (unless --nodefaultcss). The stylesheet is copied to the destination directory, unless it is an absolute url.

Some stylesheets included in the distribution are –css=navbar-left Puts a navigation bar on the left. (default omits navbar) –css=navbar-right Puts a navigation bar on the left. –css=theme-blue A blue coloring theme for headings. –css=amsart A style suitable for journal articles.

--javascript=jsfile

Includes a link to the javascript file jsfile, to be used in the transformed html/html5/xhtml. Multiple javascript files can be included; they are linked in the html in the order given. The javascript file is copied to the destination directory, unless it is an absolute url.

--icon=iconfile

Copies iconfile to the destination directory and sets up the linkage in the transformed html/html5/xhtml to use that as the ”favicon”.

--nodefaultresources

Disables the copying and inclusion of resources added by the binding files; This includes CSS, javascript or other files. This does not affect resources explicitly requested by the --css or --javascript options.

--timestamp=timestamp

Provides a timestamp (typically a time and date) to be embedded in the comments by the stock XSLT stylesheets. If you don’t supply a timestamp, the current time and date will be used. (You can use --timestamp=0 to omit the timestamp).

--xsltparameter=name:value

Passes parameters to the XSLT stylesheet. See the manual or the stylesheet itself for available parameters.

Site & Crossreferencing Options

--split, --nosplit

Enables or disables (default) the splitting of documents into multiple ‘pages’. If enabled, the the document will be split into sections, bibliography, index and appendices (if any) by default, unless --splitpath is specified.

--splitat=unit

Specifies what level of the document to split at. Should be one of chapter, section (the default), subsection or subsubsection. For more control, see --splitpath.

--splitpath=xpath

Specifies an XPath expression to select nodes that will generate separate pages. The default splitpath is //ltx:section | //ltx:bibliography | //ltx:appendix | //ltx:index

Specifying

  --splitpath="//ltx:section | //ltx:subsection
         | //ltx:bibliography | //ltx:appendix | //ltx:index"

would split the document at subsections as well as sections.

--splitnaming=(id|idrelative|label|labelrelative)

Specifies how to name the files for subdocuments created by splitting. The values id and label simply use the id or label of the subdocument’s root node for it’s filename. idrelative and labelrelative use the portion of the id or label that follows the parent document’s id or label. Furthermore, to impose structure and uniqueness, if a split document has children that are also split, that document (and it’s children) will be in a separate subdirectory with the name index.

--scan, --noscan

Enables (default) or disables the scanning of documents for ids, labels, references, indexmarks, etc, for use in filling in refs, cites, index and so on. It may be useful to disable when generating documents not based on the LaTeXML doctype.

--crossref, --nocrossref

Enables (default) or disables the filling in of references, hrefs, etc based on a previous scan (either from --scan, or --dbfile) It may be useful to disable when generating documents not based on the LaTeXML doctype.

--urlstyle=(server|negotiated|file)

This option determines the way that URLs within the documents are formatted, depending on the way they are intended to be served. The default, server, eliminates unneccessary trailing index.html. With negotiated, the trailing file extension (typically html or xhtml) are eliminated. The scheme file preserves complete (but relative) urls so that the site can be browsed as files without any server.

--navigationtoc=(context|none)

Generates a table of contents in the navigation bar; default is none. The ‘context’ style of TOC, is somewhat verbose and reveals more detail near the current page; it is most suitable for navigation bars placed on the left or right. Other styles of TOC should be developed and added here, such as a short form.

--index, --noindex

Enables (default) or disables the generation of an index from indexmarks embedded within the document. Enabling this has no effect unless there is an index element in the document (generated by \printindex).

--splitindex, --nosplitindex

Enables or disables (default) the splitting of generated indexes into separate pages per initial letter.

--bibliography=pathname

Specifies a bibliography generated from a BibTeX file to be used to fill in a bibliography element. Hand-written bibliographies placed in a thebibliography environment do not need this. The option has no effect unless there is an bibliography element in the document (generated by \bibliography).

Note that this option provides the bibliography to be used to fill in the bibliography element (generated by \bibliography); latexmlpost does not (currently) directly process and format such a bibliography.

--splitbibliography, --nosplitbibliography

Enables or disables (default) the splitting of generated bibliographies into separate pages per initial letter.

--prescan

By default latexmlpost processes a single document into one (or more; see --split) destination files in a single pass. When generating a complicated site consisting of several documents it may be advantageous to first scan through the documents to extract and store (in dbfile) cross-referencing data (such as ids, titles, urls, and so on). A later pass then has complete information allowing all documents to reference each other, and also constructs an index and bibliography that reflects the entire document set. The same effect (though less efficient) can be achieved by running latexmlpost twice, provided a dbfile is specified.

--dbfile=file

Specifies a filename to use for the crossreferencing data when using two-pass processing. This file may reside in the intermediate destination directory.

--sitedirectory=dir

Specifies the base directory of the overall web site. Pathnames in the database are stored in a form relative to this directory to make it more portable.

--embed

TODO: Deprecated, use –whatsout=fragment Requests an embeddable XHTML div (requires: –post –format=xhtml), respectively the top division of the document’s body. Caveat: This experimental mode is enabled only for fragment profile and post-processed documents (to XHTML).

Math Options

These options specify how math should be converted into other formats. Multiple formats can be requested; how they will be combined depends on the format and other options.

--noparse

Suppresses parsing math (default: parsing is on)

--parse=name

Enables parsing math (default: parsing is on) and selects parser framework ”name”. Supported: RecDescent, no Tip: –parse=no is equivalent to –noparse

--mathimages, --nomathimages

Requests or disables the conversion of math to images (png by default). Conversion is the default for html4 format.

--mathsvg, --nomathsvg

Requests or disables the conversion of math to svg images.

--mathimagemagnification=factor

Specifies the magnification used for math images (both png and svg), if they are made. Default is 1.75.

--presentationmathml, --nopresentationmathml

Requests or disables conversion of math to Presentation MathML. Conversion is the default for xhtml and html5 formats.

--linelength=number

(Experimental) Line-breaks the generated Presentation MathML so that it is no longer than number ‘characters’.

--plane1

Converts the content of Presentation MathML token elements to the appropriate Unicode Plane-1 codepoints according to the selected font, when applicable (the default).

--hackplane1

Converts the content of Presentation MathML token elements to the appropriate Unicode Plane-1 codepoints according to the selected font, but only for the mathvariants double-struck, fraktur and script. This gives support for current (as of August 2009) versions of Firefox and MathPlayer, provided a sufficient set of fonts is available (eg. STIX).

--contentmathml, --nocontentmathml

Requests or disables conversion of math to Content MathML. Conversion is disabled by default. Note that this conversion is only partially implemented.

--openmath

Requests or disables conversion of math to OpenMath. Conversion is disabled by default. Note that this conversion is only partially implemented.

--keepXMath, --xmath

By default, when any of the MathML or OpenMath conversions are used, the intermediate math representation will be removed; this option preserves it; it will be used as secondary parallel markup, when it follows the options for other math representations.

Graphics Options

--graphicimages, --nographicimages

Enables (default) or disables the conversion of graphics to web-appropriate format (png).

--graphicsmap=sourcetype.desttype

Specifies a mapping of graphics file types. Typically, graphics elements specify a graphics file that will be converted to a more appropriate file target format; for example, postscript files used for graphics with LaTeX will be converted to png format for use on the web. As with LaTeX, when a graphics file is specified without a file type, the system will search for the most appropriate target type file.

When this option is used, it overrides and replaces the defaults and provides a mapping of sourcetype to desttype. The option can be repeated to provide several mappings, with the earlier formats preferred. If the desttype is omitted, it specifies copying files of type sourcetype, unchanged.

The default settings is equivalent to having supplied the options: svg png gif jpg jpeg eps.png ps.png ai.png pdf.png

The first formats are preferred and used unchanged, while the latter ones are converted to png.

--pictureimages, --nopictureimages

Enables (default) or disables the conversion of picture environments and pstricks material into images.

--svg, --nosvg

Enables or disables (default) the conversion of picture environments and pstricks material to SVG.

Daemon, Server and Client Options

Options used only for daemonized conversions, e.g. talking to a remote server via latexmlc, or local processing via the LaTeXML::Plugin::latexmls plugin.

For reliable communication and a stable conversion experience, invoke latexmls only through the latexmlc client (you need to set –expire to a positive value, in order to request auto-spawning of a dedicated conversion server).

--autoflush=count

Automatically restart the daemon after converting ”count” inputs. Good practice for vast batch jobs. (default: 100)

--expire=secs

Set an inactivity timeout value in seconds. If the server process is not given any input for the specified duration, it will automatically terminate. The default value is 600 seconds, set to 0 to never expire, -1 to entirely opt out of using an independent server.

--address=URL

Specify server address (default: localhost)

--port=number

Specify server port (default: 3334 for math, 3344 for fragment and 3354 for standard)
