2 [========= List of things to be done. Plans, ideas, whatever... ========]
3 [========================================================================]
8 -- (EAM) Iterate over plot commands: plot for [i=1,n] ....
9 -- (EAM) Everything on command line after "load <foo>" is lost; it shouldn't be
10 -- (EAM) Fill between curves for functions (already works for data)
11 -- (EAM) set object <tag> {circle|ellipse}
17 -- gnuplot.doc: Add embedded figures from the demo set for PDF and HTML docs
19 Recently I've moved importants things from README.os2 into gnuplot.doc and
20 INSTALL; those other README.{win, xli, nex} should be
21 dispersed similarly. Who can do it?
24 -- docs/old/README.fit
25 These should be be edited and pasted into gnuplot.doc and then removed.
32 -- update its docs from docs/old/README.ami, then delete this file
35 -- update its docs from docs/old/README.emx, then delete this file
38 -- update its docs from docs/old/README.pic, then delete this file
41 -- update its docs from docs/old/README.mf, then delete this file
44 -- update its docs from docs/old/README.nex, then delete this file
47 -- Patch 559611 color + variable pointsize in pstricks
48 Can somebody comment on this?
51 -- none of the latex terminal variants support pattern-fill, but
52 they return no error if you try it.
55 -- update its docs from docs/old/README.win, then delete this file
56 -- windows driver does not report font size to windows.trm, thus
57 character widht and height are quite useless numbers
58 -- update wgnuplot menus
59 -- repair the linetype bug in wgraph.c --- crash for
60 set style fill solid border
61 plot [-2.5:4.5] 100/(1.0+x*x) with boxes lt -1
63 set style fill solid noborder
64 plot [-2.5:4.5] 100/(1.0+x*x) with boxes lt -1
67 plot [-2.5:4.5] 100/(1.0+x*x) with boxes lt -1
68 -- windows "Pause -1": it works very strange if you press <enter> while
69 having the mouse cursor out of the graph window. Mainly users running
70 demos complain about this. This bug is associated to BUG 561418
71 "(MS Windows) 100% CPU Usage during pause", and to HBB 20001217's note
72 about WaitMessage(); in wpause.c.
74 TERMINALS, GENERAL COMMENTS:
75 ============================
77 -- verify that terminals don't reset options (I've checked a lot, but
78 should be tested again)
80 -- verify that color and pointtype sequence is unified, alias similar line and
81 point type sequences for the main terminal drivers
84 GNUPLOT TOOLS LIBRARY:
85 ======================
87 Make a library (e.g. usr/local/gnuplot/scripts/, .../gnuplot/bin) of
88 (a) gnuplot scripts, and (b) shell scripts relevant for gnuplot:
90 -- enclose script "gpsavediff" that diff's output of gnuplot's "save" command
91 and default setup after "reset"
93 -- move pm3d/contrib/* files into the proposed gnuplot library, then remove
94 pm3d/contrib and pm3d/ from cvs
96 I.e., the last point is the main question: where to put pm3d/contrib/* files?
98 Or put them to gnuplot web page?
101 INSTALLATION --- LINUX:
102 =======================
104 -- add .spec file and a 'make' target to create RPM file?
108 INSTALLATION --- VMS:
109 =====================
111 -- bring configure.vms in sync with current configure.in

120 => "Feature request" for feature requests.
123 Projects, in no particular order:
125 - revise border command to use keywords
126 - put minor tics into demo file
130 - break it into four layers:
131 : low level graphics (some of term.c)
132 : plotting code, reading the setshow.h global variables
133 : parsing code - read a string, and parse and execute it
134 : front end, interact with terminal / gui
135 basically, gplotlib is layer 2, and the traditional gnuplot is
136 layer 4, which is little more than a small client of layer 3.
137 Terminal option lines are table driven,
138 so that even though the options are defined by layer 1, the
139 actual parsing is implemented in level 3
143 - much-requested feature: read text/commands from data files
144 - provide library of replacement functions instead of stdfn.c
145 - fully switch to automake [docs left to do, won't do lisp]
146 - completely rewrite the parser. Use yacc/bison if possible.
147 - maybe rewrite the scanner in lex? The benefits are not so obvious,
148 because the current scanner is extremely simple. This is probably
149 only worthwhile if the parser is rewritten at the same time.
150 - maybe use PD hash code for table-lookup (SNIPPETS code). Tables for
151 builtin and user functions, variables, commands. What else? aliases
152 - [Robert S. Maier] rewrite term.c to provide an interface to GNU plotutils
153 - standardise float/double comparisons around the suggestion in the
154 comp.lang.c FAQ (What's a good way to check for "close enough"
155 floating-point equality?) and symbolic constants from standard header files.
156 LOADS of errors throughout the code, especially in graphics.c
157 - autogenerate term.h from config file in text format and/or configure?
158 - parse "~" in filenames as $HOME
159 [PARTIALLY DONE] works for all cmds now; plot key shows "~" instead
160 of path (-> fix); does not accept "~" and "~user". Maybe implement
161 former, latter requires reading passwd file (-> not!)
162 - general expansion of user defined and environment vars in
164 - [Lucas] fix axis ranges, overwritten labels in demos
165 - write or organise a portable version of snprintf(3) with a copyright
166 compatible with the gnuplot copyright (ie. no GPL) (Apache?)
167 - add more maintainer checks (eg. file permissions)
168 - better lisp/ files integration (Makefile target to import Bruce's
169 latest version). How to handle duplicates?
170 - better documentation format; get rid of the doc2xxx utils
172 - tilde and variable expansion to be done by
173 gp_fopen() - to be implemented
174 - fix bug which prints "DI,1DI,0" in the upper left corner of the plot when
175 in pcl5 mode and printing to an HP Laserjet 4+ (J. Breeding, bug-gnuplot)
176 [HBB: reason known, but proper workaround path unclear]
179 [Optional:] See if 16-bit compilations can be made to work again.
182 - transparency (alpha channel) for fill areas and images
183 - separate out the handling of junk, NaN, Inf, and missing data entries
184 - 2D plot styles should accept color info from an extra input column
185 - you should be able to set a default style for arrows and labels
186 - isosurfaces (3D contour of 4D data)
