## Description

The -h option provides help. If it is specified without a parameter, a brief description of each option is displayed. To display the attributes for an option, specify the option letter as a parameter.

By default, generated output goes to standard output. To direct output to a file per input file, use the -o option to specify an extension for output files. If the -o option is specified without a parameter, an extension of out is assumed.

Likewise, error messages go to standard error by default. Use the -l option to create a log file per input file. If the -l option is specified without a parameter, an extension of log is assumed.

The -2 option is a convenient way of specifying the alias (collection of options) which generates the output you want. e.g.

         sdf -2html abc

is equivalent to:

         sdf +sdf2html abc

The -D option is used to define variables. These are typically used for controlling conditional text and substituting text which changes. The format used is:

     -Dvariable1=value1,variable2=value2

A flag is a shorthand way of specifying variables in the DOC family. i.e. -ftoc=3 is equivalent to -DDOC_TOC=3. The format of the -f option is:

     -fflag1=value1,flag2=value2

If a variable or flag is specified without a value, 1 is assumed.

To generate HTML topics, the command is:

         sdf -2topics abc

By default, this will create sub-topics for each heading already in a separate file. It will also autosplit level 1 headings into sub-topics. The -n option can be used to control which level headings are split at:

- 1 autosplits on level 1 headings (the default)
- 2 autosplits on level 2 headings
- 3 autosplits on level 3 headings
- 0 disables autosplitting.

Include files are searched for in the current directory, then in the directories given by the -I option, then in the default library directory.

By default, sdf is configured to prefilter files with certain extensions. For example:

     sdf mytable.tbl

is equivalent to executing sdf on a file which only contains:

     !include "mytable.pl"; table

The -p option can be used to explicitly prefilter files or to override the default prefilter used. The -a option can be used to specify prefilter parameters. For example:

     sdf -aformat='15,75,10' mytable.tbl

The -P option prefilters the input files as programming languages. The parameter is the language to use. If none is provided, the extension is assumed to be the language name. For example:

     sdf -P myapp.c

is equivalent to executing sdf on a file which only contains:

     !include "myapp.c"; example; wide; lang='c'

The -N option adds line numbers at the frequency given. The default fequency is 1. i.e. every line.

The -r option pre-filters each input by running the nominated report. Reports are stored in sdr files and are searched for using the usual rules.

The -L option can be used to specify a locale. The default locale name is specified in `sdf.ini`. Locale naming follows POSIX conventions (i.e. language_country), so the locale name for American english is en_us. The information for each locale is stored in the `locale` directory, so you'll need to have to look in there to see what locales are available. (As the default locale can be set in `sdf.ini`, this isn't as ugly as it first sounds.)

Note: At the moment, a locale file simply contains a list of language specific strings. Ultimately, it should be extended to support localisation of date and time formats.

The -k option is used to specify a look. The default look library is specified in `sdf.ini`.

The -s option can be used to specify a document style. Typical values are:

- document - a technical document
- memo - a memo
- fax - a facsimile
- minutes - minutes of a meeting.

The -S option is used to specify the page size. Values supported include:

Name | Width | Height | Comment
global | 21.0cm | 11.0in | will fit on either A4 or letter
A3 | 29.7cm | 42.0cm |
A4 | 21.0cm | 29.7cm |
A5 | 14.8cm | 21.0cm |
B4 | 25.7cm | 36.4cm |
B5 | 17.6cm | 25.0cm |
letter | 8.5in | 11.0in |
legal | 8.5in | 14.0in |
tabloid | 11.0in | 17.0in |

Additional page sizes can be configured in `sdf.ini`. To specify a rotated version of a named page size, append an R. For example, A4R implies a width of 29.7cm and a height of 21cm. A custom page size can also be specified using the format:

         {{width}}x{{height}}

where width and height are the respective sizes in points.

The -c option is used to specify a configuration library.

A list of modules to use can be specified via the -u option.

The initial heading level to start on can be specified via the -H option. If is useful if you want to preview how a topic will be displayed without regenerating the complete document.

The -d option is used to specify the format driver. Values supported include:

- expand - format as expanded text (the default)
- mif - Maker Interchange Format
- pod - Plain Old Documentation (as used by Perl).

Additional drivers can be configured in `sdf.ini`.

The -y option can to used to specify a post-filter.

The -z option can be used to specify a list of post-processing actions you want to execute on each output file after it is generated. The actions supported include:

- ps - generate PostScript
- doc - generate a Frame (binary) file
- fvo - generate a Frame View-Only file
- txt - generate a text file
- rtf - generate an RTF file
- clean - delete the output file (must be last).

Additional actions can be configured in `sdf.ini`. By convention, the generated files are given the same names as the action keywords.

The -t option is used to specify the logical target format. If none is specified, the default is the first post processing action, if any. Otherwise, the default is the format driver name.

The -v option enables verbose mode. This is useful for debugging problems related to post processing. In particular, post processing actions containing the pattern clean are skipped in verbose mode. You can also switch off the post processing messages by using a verbose value of -1.

The -w option is used to specify the width for text-based outputs.

The -z, -D, -f and -I options are list options. i.e. multiple values can be separated by commas and/or the options can be supplied multiple times.

## Examples

Convert `mydoc.sdf` to a technical document in mif format, output is `mydoc.mif`:

     sdf -2mif mydoc.sdf

Convert `mydoc.sdf` to online documentation in FrameViewer format, output is `mydoc.fvo`:

     sdf -2fvo mydoc.sdf

Convert `mydoc.sdf` to online documentation in HTML, output is `mydoc.html`:

     sdf -2html mydoc.sdf

The following command will build the reference documentation for a SDF module in HTML:

     sdf -2html abc.sdm

## Limitations and future directions

Many of the default post processing (-z) actions only works on Unix as FrameMaker for Windows does not support batch conversion.

Topics mode has several limitations:

- only documents in the current directory can be converted
- all sub-topics must also be in the current directory.
