The Settings menu and configuration files

The Settings menu is used to change the user-definable settings of texdoctk for the duration of the program call or as new defaults. The latter case is the purpose of the Save button, which generates or rewrites the user's own ~/.texdocrc file. The system defaults cannot be edited with the Settings menu.

Paths

The TEXMF-type paths on the system are reported, and the user can specify the name of the subdirectory of $HOMETEXMF, where the personal documentation is stored.

General viewer behaviour

Suppress error messages toggle verbose mode (see option -v); default is off.

Autostart viewer for one-item listboxes if a listbox contains only one item (see option -a)

Use text viewer for unknown file format i.e. treat the file as plain text. texdoctk should recognize the usual file formats and also relate names like README to plain text, but some docs may have freely invented names. Default is on; if switched off, trying to view such files will raise an error. The switch does not influence printing: unrecognized formats cannot be printed.

Change viewer colours using either RGB triplets in the format #rrggbb or the standardized names.

DVI/PostScript/PDF/HTML/Plain text

For text files, texdoctk provides an own viewer. If this viewer is disabled, but no alternative viewer is specified, texdoctk tries to read the content of the environment variable $PAGER.

If you want to print the documentations, you will need converters to turn non-PS files into PostScript. Here are some suggestions:

dvi->ps: dvips (is part of teTeX) (http://www.radicaleye.com/dvips.html)

pdf->ps: pdf2ps (http://www.cs.wisc.edu/~ghost) or Acrobat Reader (http://www.adobe.com)

html->ps: html2ps (http://user.it.uu.se/~jan/html2ps.html)

plain text->ps: a2ps (http://www-inf.enst.fr/~demaille/a2ps/)

The html->ps and text->ps converter menus for switching on/off output redirect. This is due to the fact that some converters do not write their output into a file but to stdout by default, so a redirect is needed, e.g. a2ps myfile.txt >myfile.ps

The system-wide configuration file is ($TEXMFMAIN)/texdoctk/texdocrc.defaults and should only be writable by the administrator of the installation using any text editor. The optional user configuration file is ~/.texdocrc and can override all but those system settings which affect the installation as a whole. The preferred way of changing it is through the Settings menu.

The databases

texdoctk comes with a default database file ($TEXMFMAIN)/texdoctk/texdoctk.dat with a special format. It is divided into 17 sections corresponding to the 17 buttons that are active by default. Each section begins with a line

@section_name

where section_name is the text as it appears in the button. This title is followed by the descriptive entries for each documentation, which have this format:

package-label;Short description for listbox (opt. package-name);path in doc directory;optional keywords

(without breaking the line!). Comments (initiated with a #) and empty lines are ignored by the program. The second field is the text displayed in the selection listboxes of texdoctk, and you will usually want to mention the name of the package in parens along with it; the first field is a unique label for the package for internal use of the program which will usually be chosen identical to the package name, but can be different if there is more than one documentation file coming with a package.

The administrator will probably install additional packages in the local texmf tree. The corresponding documentation can be made accessible by an additional database $TEXMFLOCAL/texdoctk/texdoctk-local.dat. Furthermore, individual users possibly install additional packages in an texmf subdirectory of their $HOME, for which they can make an individual database themselves as $TEXMFHOME/texdoctk/texdoctk-pers.dat. After creating such files, texhash must be executed.

Both types of databases must have the same structure as the system database, although they need (and should) not include all its sections if there are no additional entries. For example, if the the package foo is added to the local tree such that its documentation file is ($TEXMFLOCAL)/doc/latex/foo/foo.dvi and it is decided that it fits best into the existing category Graphics, texdoctk-local.dat would look like this:

@Graphics
foo;Create bells and whistles (foo);latex/foo/foo.dvi;decoration

The entry for foo will then be appended to the list of entries in the Graphics category. The 18th button can be activated in the same way, but using a new category name; possible entries at the beginning of the database which have not been assigned to a category will be assigned to the default Miscellaneous, making the 18th button active with that label. Note that you cannot have more than 18 categories; if there are more, only the one defined last will appear and be used.

If the documentation is included in the .sty file instead of a proper documentation file, the optional keywords should start with -?- directly after the semicolon, where ? is 0, 1, 2 or 3; these are flags which indicate in which part of the .sty the instructions are placed and should help texdoctk to extract the documentation from the style and present it without the code, which would normally be of little use.

0

no specific place, scattered between the code

1

at end, behind \endinput; some .sty files have well-organized documentation behind the end of the actual code, where TeX doesn't see it upon compilation

2

at beginning, terminated by %%%%%%; in some other cases, some usage information is at the beginning of the .sty as a comment terminated by a line full of %

3

as 2, but with a blank line as termination

See the system database for plenty of examples.
