tfrt - Tool for Function Refinement Trees
tfrt is an X11/Motif based graphical editor for drawing
function decomposition trees. Trees can be loaded from and stored to a file.
It can print trees to a PostScript printer or save as PostScript to a
file.
tfrt is part of The Toolkit for Conceptual Modeling
(TCM).
You can call tfrt with a single tree name as argument. If
this argument is an existing file then tfrt tries to load a tree from
it. If it does not exist, a new tree is created with the argument as tree
name. tfrt files should have suffix '*.frt'.
Without a tree argument, tfrt creates a new empty function
decomposition tree with the name 'untitled.frt'.
In addition to the standard X11 toolkit options (see X11(7))
tfrt accepts the options listed below:
- -drawing
widthxheight
- Create a drawing area of width pixels wide and height pixels
high.
- -help
- Write all available options to standard output and quit.
- -maxdrawing
widthxheight
- The drawing area can not be larger than width pixels wide and
height pixels high.
- -priv_cmap
- Start the editor with a private colormap.
- -projdir
directory
- Set the project directory (current working directory) to
directory.
- -toEPS
[file.eps]
- Generate EPS (to file.eps or stdout when no file name was given)
and quit.
- -toFig [file.fig]
[-latex]
- Generate Fig format (to file.fig or stdout when no file name was
given and quit. When the -latex option is given, LaTeX fonts are
generated, otherwise normal PostScript fonts are generated. The Fig format
can be read by xfig(1) and fig2dev(1).
- -toPNG
file.png
- Generate PNG format to file.png and quit.
- -toPS
[file.ps]
- Generate PostScript (to file.ps or stdout when no file name was
given) and quit.
- -version
- Write the TCM version to standard output and quit.
The TCM_HOME environment variable should be the directory
where the TCM files are installed.
- PATH
- Should include $TCM_HOME/bin
- MANPATH
- Should include $TCM_HOME/man
- PRINTER
- Name of the default printer that is used by tfrt.
- LD_LIBRARY_PATH
- Should include $TCM_HOME/lib when the distribution contains shared object
libraries in $TCM_HOME/lib.
The following relative files are relative to $TCM_HOME.
- bin/tfrt
- the function decomposition tree editor.
- bin/psf
- a program to filter PostScript output.
- lib/banner.ps
- PostScript banner page that can be used when the printer does not print a
banner page.
- lib/help/*
- The help directory contains a collection of text files for the on-line
help.
- lib/TCM
- X Resources (the same as the ones that are built-in). You can customize
the fonts and colors by setting resources in your X defaults database.
Each string of the form ``TCM.resource:definition'' sets a resource.
- /tmp/tcmXXXXXX
- Pseudo random temporary file, for PostScript output.
- lib/tcm.conf
- TCM editor configuration file. This file contains values for some of the
editor defaults like the page size, the default fonts etc. This file is
read by each editor upon startup.
- $HOME/.tcmrc
- Each user of TCM can override some of the options of tcm.conf by its own
configuration file, installed in $HOME/.tcmrc.
