Name

docbook2texi — Convert DocBook to Texinfo

Synopsis

docbook2texi [options] xml-document

Description

docbook2texi converts the given DocBook XML document into one or more Texinfo documents. By default, these Texinfo documents will be output to the current directory.

The docbook2texi command is a wrapper script for a two-step conversion process.

Options

The available options are essentially the union of the options for db2x_xsltproc and db2x_texixml.

Some commonly-used options are listed below:

--encoding=encoding: Sets the character encoding of the output.
--string-param parameter=value: Sets a stylesheet parameter (options that affect how the output looks). See “Stylesheet parameters” below for the parameters that can be set.
--sgml: Accept an SGML source document as input instead of XML.

Stylesheet parameters

captions-display-as-headings

Brief. Use heading markup for minor captions?

Default setting. 0 (boolean false)

If true, title content in some (formal) objects are rendered with the Texinfo @heading commands.

If false, captions are rendered as an emphasized paragraph.

links-use-pxref

Brief. Translate link using @pxref

Default setting. 1 (boolean true)

If true, link is translated with the hypertext followed by the cross reference in parentheses.

Otherwise, the hypertext content serves as the cross-reference name marked up using @ref. Typically info displays this contruct badly.

explicit-node-names

Brief. Insist on manually constructed Texinfo node names

Default setting. 0 (boolean false)

Elements in the source document can influence the Texinfo node name generation specifying either a xreflabel, or for the sectioning elements, a title with role='texinfo-node' in the *info container.

However, for the majority of source documents, explicit Texinfo node names are not available, and the stylesheet tries to generate a reasonable one instead, e.g. from the normal title of an element. The generated name may not be optimal. If this option is set and the stylesheet needs to generate a name, a warning is emitted and generate-id is always used for the name.

When the hashtable extension is not available, the stylesheet cannot check for node name collisions, and in this case, setting this option and using explicit node names are recommended.

This option is not set (i.e. false) by default.

Note

The absolute fallback for generating node names is using the XSLT function generate-id, and the stylesheet always emits a warning in this case regardless of the setting of explicit-node-names.

show-comments

Brief. Display comment elements?

Default setting. 1 (boolean true)

If true, comments will be displayed, otherwise they are suppressed. Comments here refers to the comment element, which will be renamed remark in DocBook V4.0, not XML comments (<-- like this -->) which are unavailable.

funcsynopsis-decoration

Brief. Decorate elements of a FuncSynopsis?

Default setting. 1 (boolean true)

If true, elements of the FuncSynopsis will be decorated (e.g. bold or italic). The decoration is controlled by functions that can be redefined in a customization layer.

function-parens

Brief. Generate parentheses after a function?

Default setting. 0 (boolean false)

If true, the formatting of a <function> element will include generated parenthesis.

refentry-display-name

Brief. Output NAME header before 'RefName'(s)?

Default setting. 1 (boolean true)

If true, a "NAME" section title is output before the list of 'RefName's.

manvolnum-in-xref

Brief. Output manvolnum as part of refentry cross-reference?

Default setting. 1 (boolean true)

if true, the manvolnum is used when cross-referencing refentrys, either with xref or citerefentry.

prefer-textobjects

Brief. Prefer textobject over imageobject?

Default setting. 1 (boolean true)

If true, the textobject in a mediaobject is preferred over any imageobject.

(Of course, for output formats other than Texinfo, you usually want to prefer the imageobject, but Info is a text-only format.)

In addition to the values true and false, this parameter may be set to 2 to indicate that both the text and the images should be output. You may want to do this because some Texinfo viewers can read images. Note that the Texinfo @image command has its own mechanism for switching between text and image output — but we do not use this here.

The default is true.

semantic-decorations

Brief. Use Texinfo semantic inline markup?

Default setting. 1 (boolean true)

If true, the semantic inline markup of DocBook is translated into (the closest) Texinfo equivalent. This is the default.

However, because the Info format is limited to plain text, the semantic inline markup is often distinguished by using explicit quotes, which may not look good. You can set this option to false to suppress these. (For finer control over the inline formatting, you can use your own stylesheet.)

custom-localization-file

Brief. URI of XML document containing custom localization data

Default setting. (blank)

This parameter specifies the URI of a XML document that describes text translations (and other locale-specific information) that is needed by the stylesheet to process the DocBook document.

The text translations pointed to by this parameter always override the default text translations (from the internal parameter localization-file). If a particular translation is not present here, the corresponding default translation is used as a fallback.

This parameter is primarily for changing certain punctuation characters used in formatting the source document. The settings for punctuation characters are often specific to the source document, but can also be dependent on the locale.

To not use custom text translations, leave this parameter as the empty string.

custom-l10n-data

Brief. XML document containing custom localization data

Default setting. document($custom-localization-file)

This parameter specifies the XML document that describes text translations (and other locale-specific information) that is needed by the stylesheet to process the DocBook document.

This parameter is internal to the stylesheet. To point to an external XML document with a URI or a file name, you should use the custom-localization-file parameter instead.

However, inside a custom stylesheet (not on the command-line) this paramter can be set to the XPath expression document(''), which will cause the custom translations directly embedded inside the custom stylesheet to be read.

author-othername-in-middle

Brief. Is othername in author a middle name?

Default setting. 1

If true, the othername of an author appears between the firstname and surname. Otherwise, othername is suppressed.

output-file

Brief. Name of the Info file

Default setting. (blank)

This parameter specifies the name of the final Info file, overriding the setting in the document itself and the automatic selection in the stylesheet. If the document is a set, this parameter has no effect.

Important

Do not include the .info extension in the name.

(Note that this parameter has nothing to do with the name of the Texi-XML output by the XSLT processor you are running this stylesheet from.)

directory-category

Brief. The categorization of the document in the Info directory

Default setting. (blank)

This is set to the category that the document should go under in the Info directory of installed Info files. For example, General Commands.

Note

Categories may also be set directly in the source document. But if this parameter is not empty, then it always overrides the setting in the source document.

directory-description

Brief. The description of the document in the Info directory

Default setting. (blank)

This is a short description of the document that appears in the Info directory of installed Info files. For example, An Interactive Plotting Program.

Note

Menu descriptions may also be set directly in the source document. But if this parameter is not empty, then it always overrides the setting in the source document.

index-category

Brief. The Texinfo index to use

Default setting. cp

The Texinfo index for indexterm and index is specified using the role attribute. If the above elements do not have a role, then the default specified by this parameter is used.

The predefined indices are:

c, cp: Concept index
f, fn: Function index
v, vr: Variable index
k, ky: Keystroke index
p, pg: Program index
d, tp: Data type index

User-defined indices are not yet supported.

qanda-defaultlabel

Brief. Sets the default for defaultlabel on QandASet.

Default setting.

If no defaultlabel attribute is specified on a QandASet, this value is used. It must be one of the legal values for the defaultlabel attribute.

qandaset-generate-toc

Brief. Is a Table of Contents created for QandASets?

Default setting.

If true, a ToC is constructed for QandASets.

Examples

$ docbook2texi tdg.xml
$ docbook2texi --encoding=utf-8//TRANSLIT tdg.xml
$ docbook2texi --string-param semantic-decorations=0 tdg.xml

Limitations

Internally there is one long pipeline of programs which your document goes through. If any segment of the pipeline fails (even trivially, like from mistyped program options), the resulting errors can be difficult to decipher — in this case, try running the components of docbook2X separately.
