NAME¶
gri - scientific graphics languageSYNOPSIS¶
gri [ OPTIONS ] [ CommandFile [ PostScriptFile ]]DESCRIPTION¶
Gri is a programming language for scientific graphics. It can make x-y graphs, contour-graphs, and image graphs. In addition, Gri has a full suite of low-level graphical elements and sufficient programming capabilities (loops, subroutines, etc) to permit complex customization.OPTIONS¶
If a command file (CommandFile) is named, commands are read from that file; otherwise they are read from the keyboard. If a command file is named, then a file in which to store the PostScript output may also be named; otherwise it is stored in a file named by substituting the .ps extension instead of .gri in CommandFile. If no command file is named, the output is named gri-00.ps (or gri-01.ps if gri-00.ps exists, etc).- Extracts the Gri commands that created the Gri PostScript file.
- Prints this help message.
- Prints the version number of Gri.
- Stops printing of prompts and hints.
-chatty[N]
or -c[N]
- Let gri print info messages
-debug
or -d
- Turns debugging on (sets variable ..debug.. to value 1).
-warn_offpage
- Warn if any item is drawn far off a 8.5x11 inch page. (This is the default.)
-nowarn_offpage
- Don't warn if any item is drawn far off a 8.5x11 inch page
-directory
pathname
- Specifies the directory where Gri looks for startup files; otherwise it looks in /opt/gri/lib or at whatever directory is defined in configure shellscript, at compile time.
-directory_default
- Reports directory where gri.cmd should be found, if not supplied by -directory.
-no_bounding_box
- Make bounding-box be full page.
-no_expecting
- Prevent warning message if `expecting version .n.' command is missing.
-no_startup_message
- Stops printing of startup message.
-publication
or -p
- Sets the builtin variable ..publication.. to 1; normally it is 0. One might use if statements (`if !..publication..' ...) on drafts.
-superuser
or -s
- Used only by Gri programmers (who can check the value with the C function `superuser()'.) An optional value can be supplied without spaces (e.g. `-s2') to set the debugging level. Flags are listed below; add flags to get several actions at once
- 1: print cmdline before/after substituting synonyms
- they are passed to the system
- 128: for author's use only
- Note that all flags are equal to 2 raised to an integer power. Since the flag values are detected by a bitwise OR, you can combine flags by adding; thus specifying a flag of 5 yields flags 1 and 4 together; specifying 15 yields flags 1, 2, 4 and 8.
-trace
or -t
- Makes Gri print out command lines as they are executed.
-true
or -y
- Makes Gri think the answer to all `query's is RETURN.
