13.2.2: Plans
Some plans for future versions are given below. A more extensive
list, together with target timescales and notes on the progress
towards completion, is available in the to-do list at the development
site (`http://gri.sourceforge.net'), which is also the place to go
if you have suggestions for other changes to Gri.
13.2.2.1: High Priority
- Add ability to generate SVG (scalable vector graphics) output. This
file type can be edited with GUI-based tools, making it easy for users
to put the final touches on graphs "manually." This feature will
require a great deal of work, mainly to do with grouping of graphical
elements, and so I'll need to rely on advice from users.
- Switch to `
popt' library for the processing of command-line
options. (Docs on this are at
`http://cvs.gnome.org/lxr/source/popt'.)
- Change `
set axes style' from number-based selection to
word-based selection, and print a deprecation warning if the
number-based syntax is used.
- Switch from `
tmpname' to `mkstemp' subroutine, for temporary filenames.
- Add readline support, to handle history, command-line editing, etc,
for interactive usage
(Docs on this are at
`
http://cnswww.cns.cwru.edu/~chet/readline/readline.html'.)
13.2.2.2: Medium priority
- Add optimal interpolation as another method for gridding
data (see Convert Columns To Grid).
- Add ability to read PNG images (see Read Image)
(Docs on this are at `
http://www.libpng.org/pub/png/'.)
13.2.2.3: Low priority
- Add non-RPN mathematics.
- Add graphical output to the screen as commands are executed.
- Add support for both little-endian and big-endian binary data.
