FRUNDIS(1) General Commands Manual FRUNDIS(1)

frundisexporting tool for the frundis markup language

frundis -T format [-a] [-s] [-t] [-x] [-z] [-o output-file] path

The frundis program reads an UTF-8 encoded file given by path, written in the frundis language as documented in frundis_syntax(5), and exports it to LaTeX, XHTML, EPUB, markdown or groff mom. The markdown and groff mom exports are second-class, and they only handle a subset of the language: see the FORMATS section of frundis_syntax(5) for more details.

The options are as follows:

format
Specify the format in which to export. The format argument can be latex, xhtml, epub, markdown or mom.
When exporting to XHTML, output only one file, instead of a directory with one file per part or chapter, and implies also that -s is no longer the default.
output-file
Specify the name of an output file, instead of printing to stdout. In the case of exporting to EPUB, and XHTML unless -a is specified, this option is mandatory and specifies the name of a new directory that will contain all the necessary files. For EPUB, zipping has to be done manually after, or by using the -z option.
Specify that a standalone document should be produced. This is the default for XHTML and EPUB output formats.
Use template-like restricted mode (experimental).
Allow #run macro and external filters. Use this option only for trusted sources.
When exporting to EPUB, produce a finalized compressed EPUB file with the name suffix ‘.epub’.

frundis uses the following environment variables:

This variable can be used to specify a colon separated list of directories in which to search for frundis included source files.

examples/
This directory available in the root of the distribution contains examples for easy customization of output.
examples/stylesheet.css
Example stylesheet for easy customization of XHTML and EPUB output formats.
examples/preamble.tex
Example of preamble for LaTeX for easy customization.

To print simple XHTML without headers:

$ frundis -a -T xhtml input.frundis > output.html

To print a standalone XHTML:

$ frundis -a -s -T xhtml input.frundis > output.html

To create a directory with XHTML files and an index:

$ frundis -T xhtml -o output-dir input.frundis

The following command will create an EPUB, both the uncompressed directory with the contents, named ‘output’, and the compressed, ready-to-use EPUB file ‘output.epub’:

$ frundis -T epub -o output -z input.frundis

If the -z option is ommited, compression can be done manually. Assuming the zip program from http://infozip.sourceforge.net/ is installed:

$ frundis -T epub -o output-dir input.frundis
$ cd output-dir
$ zip -X0 ../my-epub.epub mimetype
$ zip -Xur9D ../my-epub.epub *

To produce a LaTeX document without a preamble:

$ frundis -T latex input.frundis > output.tex

To produce a complete LaTeX document:

$ frundis -s -T latex input.frundis > output.tex

To produce a pdf document using groff mom output format:

$ frundis -s -T mom input.frundis > output.mom
$ pdfmom -k -t output.mom > output.pdf

Standard error messages have the following form:

frundis: file:lnum:macro: message

The file field specifies the name of the source file in which an error was encountered. It can be stdin when reading from standard input. The lnum field specifies the number of the line in the source file where the error has been detected. The macro field is the name of the macro being called (if any). One or more message fields provide further details on the nature of the error.

The file, lnum and macro fields appear only when it makes sense.
