This is ChangeLog for gnuplot development period from April 1998 until April 2004
when gnuplot 4.0 was released
=================================================================================
2004-04-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* README: Mention CTAN as a distributor.
2004-04-15 Ethan Merritt <merritt@u.washington.edu>
* INSTALL: Give more complete description of the environmental
variables GNUPLOT_FONTPATH, GNUPLOT_DEFAULT_GDFONT and GDFONTPATH.
2004-04-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/version.c (gnuplot_date): Raised for yet another tarball.
* docs/gnuplot.texi: Regenerated.
* src/show.c (show_version): Updated the splash text another time.
2004-04-15 Petr Mikulik <mikulik@physics.muni.cz>
* NEWS: Updated.
* README.1ST: Updated.
* BUGS: Updated.
* docs/gnuplot.doc: Section "New features" reformatted to 80 chars
width.
* docs/gpcard.tex: Updated.
2004-04-14 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/plot.c (get_user_env): Check $USERPROFILE on Windows, before
giving up on finding a $HOME.
* docs/gnuplot.doc (startup, environment): Document the behaviour
regarding USERPROFILE.
* docs/gnuplot.texi: Recreated.
2004-04-14 Petr Mikulik <mikulik@physics.muni.cz>
* FAQ: Updated for gnuplot 4.0.
* pm3d/README: Updated.
* lisp/gpelcard.tex: Corrected "pm3d" instead of "mouse".
2004-04-14 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/version.c: Activate "RELEASE_VERSION" code by inserting a
#define.
(HELPMAIL, CONTACT): Provide fall-back definitions.
* src/show.c (show_version): Update splash text for better
formatting, and to get of the "pre-release" status.
* TODO: Lots of small updates.
* BUGS: Moved one bug from TODO to here.
* INSTALL.gnu: Updated to more current upstream (FSF) version.
2004-04-13 Ethan Merritt <merritt@u.washington.edu>
* term/x11.trm: If gnuplot_x11 dies, or fails to start, then make
sure all locks on the [now defunct] pipe are cleared.
2004-04-13 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* PATCHLEVEL: Reset to zero.
* VERSION: Updated to 4.0 for the release.
* All over the place: Removed pointers to mailing lists at
Dartmouth from all source files. Updated Copyright statements to
list 2004 as one of the years. Changed remaining references to
mailing lists to the new ones as SourceForge.net.
* docs/gpcard.tex: Small updates to reflect at least the major
changes since 3.7.
* lisp/README.1st: A new file to explain the relation between this
directory and the stand-alone gnuplot-mode package made by Bruce
Ravel.
* lisp/configure.in: Set AC_PREREQ() to 2.52 like in the master
configure.in, to avoid strange interactions caused by mixed
autoconf versions.
* tutorial/.cvsignore: Ignore *.toc files, too.
* term/gd.trm (PNG_options): Bugfix: font options "tiny"
... "giant" failed to unset the freetype "font" option.
2004-04-12 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/command.c (do_system) [!USE_OWN_WINSYSTEM_FUNCTION]: disable
usage of winsystem(), which apparently causes more trouble than
it's worth. To re-enable this, manually #define the
USE_OWN_WINSYSTEM_FUNCTION macro.
2003-04-10 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* INSTALL: Include a notice about the demise of 16-bit versions on
MS-DOS and Windows. Updated the paragraph about the history of
gnuplot-mode.
* README.1ST: Updated. Added a paragraph about PDFlib licensing.
* README: Updated to reflect imminent release. Changed text about
mailing lists. Added pointers to the web pages at SF.net.
Removed some mirrors that don't exist any longer.
* src/fit.c (Dblfn): Re-initialize va_args between uses. Needed
to be C standard compliant and survive running on Linux/AMD64.
(Fixes SF bug #932162).
2004-04-08 Ethan Merritt <merritt@u.washington.edu>
* src/readline.c: Revert patch from 2003-05-10 "Allow <tab>
characters in input stream." This broke filename auto- completion
by gnu libreadline. Reversion re-introduces the problem that
gnuplot's own readline makes it impossible to enter <tabs> in a
command line.
2004-04-08 Petr Mikulik <mikulik@physics.muni.cz>
* TODO: Updated.
* INSTALL: Updated.
2004-04-07 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/set.c (looks_like_numeric): Recognize blanks and other
special formatting characters in floating point formats correctly.
* src/save.c (save_set_all): Moved writing of timefmt strings up
in the list of saved settings, so 'set xtics' can have time/date
strings as endpoints.
2004-04-05 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* BUGS: Removed lots of long-since fixed bugs. Updated
descriptions of some others. Got rid of numbering --- it was
completely mixed-up anyway.
* term/win.trm: Added a note regarding the limitation of no wide,
patterned lines in Windows terminal.
2004-04-05 Petr Mikulik <mikulik@physics.muni.cz>
* BUGS: Removed point "8. contour line clipping of 3D data plots":
it should go to FAQ or to gnuplot's web page => "Useful
scripts". Removed point "11. bug in OS/2 emx/gcc 2.7.x optimizer"
(cite this in makefile.os2). Added link to gnuplot's sourceforge
bug tracker.
* config/README: Small update.
* config/makefile.os2: Mention compiler optimization problem from
BUGS.
2004-04-04 Ethan Merritt <merritt@u.washington.edu>
* term/svg.trm: 'Set term svg {fontfile <filename>}' option to embed a
font, or a hyperlink to it, in the output svg document. This allows the
use of symbol fonts in conjunction with enhanced text mode. The file
search path is controlled by environmental variable GNUPLOT_FONTPATH.
2004-04-01 Petr Mikulik <mikulik@physics.muni.cz>
* src/plot.c: Fix OS/2 release version string if wrong in using
utsname.h.
* src/mouse.c: On OS/2, don't start with mouse on by default. For some
unknown reason, it clashes with arrow keys and even palette color
allocation in multiplot mode... I guess these strange features are in
gnuplot for ages, as it was always recommended to put "unset mouse"
into gnuplot.ini.
* FAQ: Updated to current version.
Technote: not used "lynx -dump" from its Makefile (spurious references
left) but from menu "Save formatted document" in links in xterm with
80 columns.
2004-03-31 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/graph3d.c (do_3dplot): Ignore "set grid {back|front}" in
hidden3d mode --- they would directly contradict the idea of
hidden-line removal.
* docs/gnuplot.doc (grid): Document effect of hidden3d mode on
options "back" and "front".
(border, xtics): Document that "set grid {front|back}" also
controls the drawing order of border and ticmarks.
(xtics axis): Describe actual effect of on-axis tics coming too
close to the graph border.
* configure.in: New options --enable-h3d-quadtree and
--enable-h3d-gridbox to control compile-time flags of hidden3d
code.
* src/show.c (show_version): Lots of mostly stylistic changes to
"show version long" part. Replaced long comma-separated chain of
assignment statements by individual initialized variable
definitions. Added printouts for new feature macros
HIDDEN3D_GRIDBOX and HIDDEN3D_QUADTREE. Joined string output by
fputs into the fprintf() format string. Broke the list of
compiler flags into two lines.
* src/hidden3d.c (HIDDEN3D_GRIDBOX, HIDDEN3D_QUADTREE): Renamed to
avoid namespace collisions since these are now globally visible.
Used to be called TEST_GRIDBOX and TEST_QUADTREE. Changes occur
all over hidden3d.c.
2004-03-30 Ethan Merritt <merritt@u.washington.edu>
* src/axis.c: Fix another case of arithmetic assignment to a
boolean.
2004-03-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/graph3d.c (plot3d_lines_pm3d, plot3d_points_pm3d,
get_surface_cbminmax): Make local copy of
plot->pm3d_color_from_column a TBOOLEAN.
* src/pm3d.c (pm3d_plot): Likewise.
* src/hidden3d.c (in_front): Simplify by removing almost-boolean
local variables v{1,2}_inside_p.
2004-03-29 Ethan Merritt <merritt@u.washington.edu>
* src/hiddden3d.c: Must not do arithmetic using TBOOLEANs!!!
2004-03-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* PATCHLEVEL: Increased for yet another release candidate tarball.
* src/version.c: Updated accordingly.
* lisp/.cvsignore: Add autom4te.cache to set of ignored names.
2004-03-29 Lars Hecking <lhecking@nmrc.ucc.ie>
* tutorial/Makefile.am.in: Add tutorial.toc to CLEANFILES.
2004-03-29 Per Persson <persquare@users.sf.net>
* term/aquaterm.trm: Major update to driver.
Built if libaquaterm present, requires AquaTerm 1.0 or later.
2004-03-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
Fix up a blunder exposed by making TBOOLEAN an actual boolean
type: the TBOOLEAN argument "head" of term->arrow() was misused as
an integer.
* src/term_api.h (TERMENTRY): Change type of argument "head" of
function pointer "arrow" to int.
* src/term.c (do_arrow): Changed type of argument 'head' to int.
* term/tpic.trm (TPIC_arrow): Likewise.
* term/tgif.trm (TGIF_arrow): Likewise.
* term/texdraw.trm (TEXDRAW_arrow): Likewise.
* term/pstricks.trm (PSTRICKS_arrow): Likewise.
* term/metapost.trm (MP_arrow): Likewise.
* term/metafont.trm (MF_arrow): Likewise.
* term/latex.trm (LATEX_arrow): Likewise.
(best_latex_arrow): Likewise.
* term/gpic.trm (GPIC_arrow): Likewise.
* term/fig.trm (FIG_arrow): Likewise.
* term/epslatex.trm (EPSL_arrow): Likewise.
* term/eepic.trm (EEPIC_arrow): Likewise.
* term/dumb.trm (DUMB_arrow): Likewise.
2004-03-27 Ethan Merritt <merritt@u.washington.edu>
* term/svg.trm: Further fixes to enhanced text mode. Revise option
parsing so that it is not sensitive to the command line order.
2004-03-26 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* config/config.nt: Remove HAVE_STDBOOL_H and HAVE__BOOL again ---
turns out MSVC doesn't have them.
2004-03-26 Petr Mikulik <mikulik@physics.muni.cz>
* config/makefile.cyg: Added -DHAVE_STDBOOL_H to the compile
command for pgnuplot.exe to avoid compiler warnings.
2004-03-25 Ethan Merritt <merritt@u.washington.edu>
* term/x11.trm: Prevent wrap-around of ruler coordinates.
2004-03-25 Petr Mikulik <mikulik@physics.muni.cz>
* src/gplt_x11.c: References to pipe_died must be surrounded by
#ifdef PIPE_IPC.
* config/config.os2: #undefine HAVE_STDBOOL_H and HAVE__BOOL.
2004-03-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* config/config.amg config/config.cyg config/config.mgw
config/config.nt config/config.os2: Added new macros
HAVE_STDBOOL_H and HAVE__BOOL needed by my change to the TBOOLEAN
setup in syscfg.h two days ago.
* src/term.c (curr_arrow_headfilled): Changed type from TBOOLEAN
to int, because this variable has more than 2 possible values.
* src/term_api.h (curr_arrow_headfilled): Changed extern
declaration accordingly.
2004-03-24 Ethan Merritt <merritt@u.washington.edu>
* src/gplt_x11.c: Change window size immediately on 'm' toggle.
* term/gd.trm: Update comments on libgd version requirements.
2004-03-23 Ethan Merritt <merritt@u.washington.edu>
* src/gplt_x11.c: If gnuplot exits while "x11 -persist" is active,
hand over mousing of last active plot to gnuplot_x11. This fixes
the test case provided with bug #921033. Also, continue to honor
'm' key as a toggle for mousing in detached windows.
2004-03-23 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* configure.in (AC_HEADER_STDBOOL): Added call to this macro.
* src/syscfg.h: Rewrite the definition of FALSE, TRUE and TBOOLEAN
from scratch, this time based on autoconf's recommendations. The
previous version collided with a "#define bool _Bool" found
somewhere deep in the Mac OS X system headers.
2004-03-23 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/axis.c (t_timelevel): Start enum values at 1, to avoid
wrap-around of expression TIMELEVEL_SECONDS - 1.
(make_auto_time_minitics): Fine-tune thresholds and generate tick
step sizes to get more sensible minor tick steps.
(quantize_time_tics): Only set timelevel[axis] to a higher value
if the tic step is at least one unit long.
(time_tic_just): Remove superfluous update of local variable just
before exit from function.
(setup_tics): Handle reverted time/date axes correctly.
2004-03-22 Ethan Merritt <merritt@u.washington.edu>
* src/term.c src/gplt_x11.c term/gd.trm term/pdf.trm term/x11.trm
term/dumb.trm term/post.trm: Revamp the implementation of the '@'
character (phantom box) in enhanced text processing. This fixes
bug #906056 "@-aligned string does not work with font change".
Basically it adds a save/restore position command to the
term->enhanced_open() routine, and brackets the @-text with a save
and restore. Probably a PostScript guru can beautify my code
further.
2004-03-21 Ethan Merritt <merritt@u.washington.edu>
* term/svg.trm: Add an enhanced text mode for the svg
terminal. It's not perfect, but it works well enough to overcome
some of the text formatting limitations in the svg plain text
mode.
2004-03-18 Ethan Merritt <merritt@u.washington.edu>
* term/dumb.trm: Fix segfault on 'unset output' while in dumb
terminal.
2004-03-15 Hans-Bernhard Broeker <broeker@ac3b07.physik.rwth-aachen.de>
* src/axis.c (load_range): Un-set 'reverse' option if fixed range
specification is given in forward order.
2004-03-12 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* PATCHLEVEL: Raised to 2 for new release candidate.
* src/version.c: Updated.
* docs/doc2texi.el (d2t-texi-header): Updated version to 4.0,
changed "organized by" entry from Dave to Lars. Added Copyright
year entry for 2004.
* docs/titlepag.ms: Likewise.
* docs/gnuplot.texi: Regenerated.
* docs/Makefile.in ($(srcdir)/gnuplot.texi): Renamed rule target
to include $(srcdir). Fixed copy command to pull gnuplot.doc,
into build directory, not gnuplot.texi.
2004-03-11 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
The fix for SF bug "[905651] Grid and border overlap the plot".
This is rather elaborate, unfortunately:
* src/graph3d.c (USE_GRID_LAYERS): New feature test macro. Turned
on automatically for now. If PM3D is on , this is forced on, too.
(whichgrid): Removed global variable.
(do_3dplot) [USE_GRID_LAYERS]: Draw back part of grid before the
plotted data/functions, and front part afterwards, by passing a
new argument to draw_3d_graphbox().
(draw_3d_graphbox): Added new argument 'whichgrid' to control
which parts of the graph box will be drawn. Default is ALLGRID,
i.e. draw all of it. All calls updated accordingly.
(draw_3d_graphbox) [USE_GRID_LAYERS]: Use new parameter to decide
which parts to actually draw. Changed #if PM3D to USE_GRID_LAYERS
to enable this former PM3D-only code for general usage.
(xtick_callback, ytick_callback, ztick_allback): Removed former
PM3D-only checks --- they're done in graphbox now, before calling
gen_tics().
* src/pm3d.h (PM3D_HAVE_SOLID): New macro, default value zero.
Disables pm3d option {transparent|solid}, which is no longer
needed --- it's a duplicate of what 'set grid front' already
achieves.
(pm3d_struct) [!PM3D_HAVE_SOLID]: Remove struct field
corresponding to disabled option.
* src/pm3d.c (pm3d) [!PM3D_HAVE_SOLID]: Remove initializer of
removed struct field.
(pm3d_reset) [!PM3D_HAVE_SOLID]: Remove operation to clear removed
struct field.
* src/set.c (set_pm3d) [!PM3D_HAVE_SOLID]: Ignore disabled option,
warn if running interactively.
* src/show.c (show_pm3d) [!PM3D_HAVE_SOLID]: Disable display of
removed option.
* src/save.c (save_set_all) [!PM3D_HAVE_SOLID]: Disable saving of
removed option.
* docs/gnuplot.doc (pm3d): Removed documentation of no longer
existant option.
(grid): Document new default layering of 3D grid/boundary.
2004-03-11 Petr Mikulik <mikulik@physics.muni.cz>
* tutorial/tutorial.tex tutorial/header.tex: Updates about
TeX-friendly terminals in gnuplot 4.0.
* term/gd.trm term/gif.trm: Don't print debugging message.
2004-03-10 Ethan Merritt <merritt@u.washington.edu>
* term/cgm.trm: Revise the conditional code sections so that it is
possible to select USE_ULIG_FILLEDBOXES without PM3D.
2004-03-09 Petr Mikulik <mikulik@physics.muni.cz>
* src/os2/gnupmdrv.rc: Renamed menu entry "~data style" to "style
~data", and same for "~function".
* config/config.mgw config/config.os2: #define
HAVE_TIME_T_IN_TIME_H.
* ChangeLog: Fixed typos and spaces in author names and their
e-mails in ChangeLog entries.
2004-03-08 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* docs/doc2texi.el: Add @dircategory Math to place the gnuplot
info file into a suitable place in the master info directory page.
* docs/gnuplot.texi: Updated accordingly.
2004-03-07 Ethan Merritt <merritt@u.washington.edu>
* src/gplt_x11.c: Selecting linetype -2 worked only because bounds
checking was incorrect. Now treat LT_BACKGROUND, LT_NODRAW, and
other negative linetypes as a request for the background color.
* src/term.c: Allow explicit vertical offset of 0 in enhanced text
mode overprint statement. Patch by Harald Harders (SF.net bug
report #911068). Overprint positioning remains inexact at best in
non-PostScript drivers.
2004-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/axis.h (STORE_WITH_LOG_AND_UPDATE_RANGE): Added check
against infinities and NaNs. Most paths were already blocked, but
modern systems can have "inf" and "nan" right in the datafile,
which wasn't tested against.
2004-03-03 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* docs/gnuplot.doc (fit): Clarify behaviour in case no "using"
specification was given.
2004-03-02 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/standard.c (f_tanh): Added extra code to return an exact 1.0
for large absolute arguments. Fixes SF bug #908184.
* term/x11.trm [TERM_HELP]: Explain colour control via command
line options more clearly, including the -xrm for colors other
than the background.
* docs/gnuplot.doc (random, palette): Fixed entries showing up as
sub-topics in the wrong places of gnuplot.gih.
2004-03-02 Petr Mikulik <mikulik@physics.muni.cz>
* docs/gnuplot.doc term/x11.trm: Fix entries appearing in 'help
help'.
2004-02-27 Ethan Merritt <merritt@u.washington.edu>
* term/mif.trm: Revise #ifdef so that it compiles if you select
configure --disable-filledboxes
* src/gplt_x11.c: Add #ifdef so that it compiles if you select
configure --disable-pm3d
2004-02-27 Petr Mikulik <mikulik@physics.muni.cz>
* config/config.cyg config/config.mgw config/config.os2: Shape
these config files to the form of config.hin generated by
./configure. This will more easily facilitate to synchronize
particular #(un)define options added to the ./configure procedure
in future.
2004-02-27 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
Fix SF bug [ 905691 ] "save" does not save correct arrow heads.
* src/term_api.h (t_arrow_head): New enum type to provide manifest
constants for arrow head choices.
(arrow_head_names): Added declaration of new global in term.c.
(arrow_style_type): Change type of member "head" from int to new
enum.
* src/term.c: Define constant strings for arrow head placement
options.
* src/save.c (save_set_all): Use new string constant to correctly
output head placement options.
2004-02-27 Petr Mikulik <mikulik@physics.muni.cz>
* docs/gnuplot.doc term/x11.trm: Added missing labels for hypertext
references.
2004-02-24 Petr Mikulik <mikulik@physics.muni.cz>
* config/config.amg config/config.cyg config/config.mgw
config/config.os2: Changed GP_FIT_ERRVARS from #undef to #define
(complies with the default value of ./configure).
2004-02-23 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* docs/gnuplot.doc (bind, mouse variables, if, using, label,
mouse, x11 mouse, pm3d, palette, style arrow, style line): Removed
help entries that would go directly under 'help'.
(pm3d): Remove help entries that suggest 'set pm3d' has sub-nodes:
it doesn't.
* term/vgagl.trm [TERM_HELP]: Removed help entries that would go
directly under 'help'.
* term/x11.trm: Likewise.
* term/pc.trm (PC_move, PC_vector, PC_put_text): Change coordinate
arguments to unsigned int to match terminal API.
* src/term.h [DOS386]: Allow DOS386 platforms to load the
PC-specific driver section, too (--> Watcom).
* src/plot3d.h: Prepend 'extern' to turn erroneous definition into
a declaration.
* src/plot3d.c (plot_has_palette): Moved definition here, from
src/plot3d.h.
* src/plot.c (main): Leave at end of main using return statement,
not the exit() system call. Exit() confuses compilers that expect
main to return an int.
* src/bf_test.c (main): Likewise.
* docs/doc2tex.c docs/doc2rnh.c docs/doc2ms.c docs/doc2ipf.c
docs/doc2hlp.c docs/doc2gih.c docs/checkdoc.c (main): Likewise.
* docs/doc2rnh.c (main): Replace one EXIT_SUCCESS returned on
error condition by EXIT_FAILURE.
* config/makefile.wc: Lots of changes to make this ancient
orphaned file workable with current releases of the Watcom
compiler. Will need further files config/config.wc
src/makefile.awc and to actually work, though. Converted to Unix
text file format in CVS.
* config/README: Converted to Unix text file format.
* config/config.cyg (HAVE_TIME_T_IN_TIME_H): Add this missing
configuration item.
2004-02-22 Ethan Merritt <merritt@u.washington.edu>
* src/gplt_x11.c: When drawing rotated text, only modify pixels
that actually contain part of the text. Fixes bug #668782. Patch
originally submitted by Mike Sutton
<suttonm@users.sourceforge.net>, lightly modified by me. NB: This
code makes refreshing the plot window very slow if rotated text is
present. It is particularly noticeable when the window is
resized.
2004-02-22 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
Fix SF bug: [ 666462 ] steps/histeps calculation/display problem.
* src/graphics.c (edge_intersect_steps, ): Replace invidual tests
against axis range ends by calls to macro cliptorange(), which can
handle reverted ranges.
(edge_intersect_fsteps): Likewise.
(two_edge_intersect): Use GPMAX() of axis endpoints instead of
axis.max element to compare to, again to avoid surprises with
reverted axes.
(do_key_sample): De-ANSI-fied. Reindented.
2004-02-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
Tagged a patchlevel 1 to incorporate some post-last-minute
changes:
* PATCHLEVEL: Incremented by 1 for these post-release changes.
* src/version.c: Updated.
* configure.in (X11 handling): Append ${EXEEXT} to gnuplot_x11
program name to allow building on X11 platforms that use .exe
extensions for programs (Win32, OS/2).
* config/config.mgw config/config.cyg config/config.os2: Remove
'#' lines that aren't actual preprocessor commands.
* src/win/wgraph.c (GraphStart): Don't grab keyboard focus unless
mouse mode is on.
2004-02-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* demo/electron.dem (3rd plot): Use "set key default" to get a
sensible position of the key. Without it, it's outside the page
and you get terminal driver errors.
2004-02-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
Tagged and released version 3.8k.0, which also serves as release
candidate #1 for release as version 4.0.
2004-02-18 Ethan Merritt <merritt@u.washington.edu>
* src/readline.c term/x11.trm: Patch by Bill Fenner fixing bug
#899245, suspend/resume with gnu readline requires us to trap
EINTR.
2004-02-18 Ethan Merritt <merritt@u.washington.edu>
* demo/webify.pl demo/Makefile.am.in: Make output html compliant
with 4.0.1 transitional standard. Add enhancedtext.dem to the
list of auto-generated html pages.
2004-02-18 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* configure.in (--disable-defined-var): Remove annotation as
EXPERIMENTAL.
(--disable-fiterrvars): Changed default to enabled, removed
annotation as EXPERIMENTAL.
2004-02-18 Petr Mikulik <mikulik@physics.muni.cz>
* config/config.cyg config/config.mgw config/config.os2: Added
#undef GP_FIT_ERRVARS and #define GP_ISVAR.
* src/plot3d.c: Issue a warning when trying to draw surface with
pm3d style and there has not been previous "set pm3d". Maybe we
could refrain from this requirement in future by adding new field
'pm3d.on' to 'pm3d.where' in 'struct pm3d'.
2004-02-15 Ethan Merritt <merritt@u.washington.edu>
* src/gplt_x11.c src/plot3d.c src/pm3d.c: Trivial changes to
prevent stupid compiler warnings.
2004-02-13 Ethan Merritt <merritt@u.washington.edu>
* demo/prob.dem demo/prob2.dem: pause(-1) after final plot
* term/svg.trm term/post.trm: Rearrange things slightly so that
the output code is less ugly (cleanup of my 1 Feb 2004 patch).
2004-02-13 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* config/makefile.nt (makefile.nt, config.h): Copy makefile.nt and
config.nt over into the src directory, if necessary.
* src/time.c [!USE_SYSTEM_TIME] (gstrptime): Replace
implementation of %s format. Now reads in a double-precision
number and uses gnuplot's own ggmtime() routine instead of library
function gmtime(). This should fix SF bug #885279 "Reading '%s'
timefmt is not 64 bit safe".
(CHECK_SPACE, COPY_STRING, FORMAT_STRING): Macros moved inside
function xstrftime() they belong to. Changed to use do {...}
while(0) pattern. #undef them after use.
(xstrftime): Changed return type to size_t to avoid warnings.
(LETTER, NOTHING): Macros moved into function gstrptime() they
belong to. #undef them after use.
2004-02-13 Petr Mikulik <mikulik@physics.muni.cz>
* config/config.os2: Add SELECT_TYPE_ARG* definitions.
2004-02-12 Ethan Merritt <merritt@u.washington.edu>
* src/specfun.c demo/random.dem docs/gnuplot.doc:
Modify behaviour of rand() function in response to bug report #870706
rand(0) returns a pseudorandom number generated from current seeds
rand(-1) resets both seeds to a standard value
rand(x) for x>0 sets both 32-bit seeds to x
rand({x,y}) for x>0 sets seed1 to x and seed2 to y
2004-02-12 Petr Mikulik <mikulik@physics.muni.cz>
* src/os2/gclient.c: Let the color sequence of the first 5 line
types be the same as in postscript.
* src/term.c (do_point): Let sequence of the 6 defined point types
be the same as in postscript, png and x11.
2004-02-12 Petr Mikulik <mikulik@physics.muni.cz>
* NEWS src/plot.c src/win/winmain.c src/win/pgnuplot.c
term/win.trm: Let gnuplot on Windows accept the '-persist' command
line option (preferred synonym to '-noend' and '/noend').
2004-02-12 Petr Mikulik <mikulik@physics.muni.cz>
* config/makefile.cyg config/makefile.mgw: Missing copy of file
VERSION into the latexing directory.
2004-02-01 Ethan Merritt <merritt@u.washington.edu>
* term/gd.trm term/post.trm term/pdf.trm term/svg.trm: In the rare
case of a request to draw a line or polygon-fill with LT_NODRAW or
LT_BACKGROUND it makes more sense to set the color to white than
to black. The x11 terminal already behaves this way.
2004-01-25 Ethan Merritt <merritt@u.washington.edu>
* term/gd.trm docs/gnuplot.doc: Take default font for gdlib
terminals (png jpeg) from environmental variable
GNUPLOT_DEFAULT_GDFONT.
2004-01-20 Petr Mikulik <mikulik@physics.muni.cz>
* docs/Makefile.in: gnuplot.tex needs to be latexed 3 times (it
contains multipage toc).
2004-01-19 Petr Mikulik <mikulik@physics.muni.cz>
* config/makefile.cyg config/makefile.mgw config/makefile.os2:
Copy file VERSION into the latexing directory (setting TEXINPUTS
from within Makefile does not portably work).
2004-01-17 Ethan Merritt <merritt@u.washington.edu>
* src/save.c src/save.h src/show.c: Consolidate the save and show
routines for data and function plot styles into a single place.
2004-01-14 Lars Hecking <lhecking@nmrc.ucc.ie>
* Makefile.am: Remove superfluous files from LISP_DISTCLEANFILES.
* docs/Makefile.in: Add $(top_srcdir) to TEXINPUTS. Add installcheck
target. Fix uninstall-gih and uninstall-info targets.
* docs/titlepag.tex: Remove path to VERSION file, this is now taken
care of by TEXINPUTS.
* lisp/Makefile.am: Remove superfluous files from DISTCLEANFILES.
Remove dist-hook.
* src/Makefile.am: Include PKG_MAJOR in pkglibexecdir. Adjust
X11_DRIVER_DIR accordingly. New variable pkglibexec_PROGRAMS for
gnuplot_x11, remove install-exec-local and uninstall-local targets
as automake creates them for pkglibexec_PROGRAMS.
2004-01-13 Ethan Merritt <merritt@u.washington.edu>
* src/save.c: The color axis format was not being saved; now it is.
2004-01-12 Ethan Merritt <merritt@u.washington.edu>
* demo/webify.pl demo/mgr.pl demo/polar.dem demo/random:
Use 'print' rather than 'pause 0' in demos to avoid empty plots.
Have webify.pl delete empty *.png files on exit. If gpsavediff is
available, use it to create a script for each plot. If gnuplot.css
is present, reference it as a stylesheet.
2004-01-11 Ethan Merritt <merritt@u.washington.edu>
* src/command.c, src/term.c, term/x11.trm, docs/gnuplot.doc:
Add sanity checks to 'pause mouse' command; give a warning if mousing
is not active. For X11, do *not* terminate 'pause mouse' on normal
input from stdin. This is necessary to allow 'pause mouse' to work
from piped input since more commands may already be queued up in stdin.
2004-01-10 Petr Mikulik <mikulik@physics.muni.cz>
* pm3d.c (geomean4): Support negative values to help splot surfaces with
all color coordinates negative and "set pm3d corners2color geomean".
* gplt_x11.c: Print the debugging message "gnuplot_x11 3769: mouse
button 1 from window 1 at 0 0" only #ifdef DEBUG.
2004-01-08 Lars Hecking <lhecking@nmrc.ucc.ie>
* lisp/configure.in: Remove superfluous file copying commands, now
taken care of by auto* tools.
* src/gplt_x11.c(pr_window): Bugfix: static array must be computable
at compile time.
2004-01-07 Ethan Merritt <merritt@u.washington.edu>
* src/plot.c, term/x11.trm: Set stdin to unbuffered on program entry
rather than waiting for the start of an X11 plot. All buffered input
is lost by the call to setvbuf(), so the only safe time to call it is
before there is any input. This fixes the latest manifestation of the
"x11 clipboard paste problem", and also the "piping from awk" problem.
2004-01-07 Lars Hecking <lhecking@nmrc.ucc.ie>
* configure.in, configure.vms, src/fit.c, src/gplt_x11.c, src/stdfn.h,
term/ggi.trm, term/x11.trm: Use AC_FUNC_SELECT_ARGTYPES instead of
AC_FUNC_SELECT and related changes.
* config/config.amg: Updated.
* docs/gnuplot.doc: Removed whitespace-only line as pointed out by
"make check".
* m4/apple.m4, m4/beos.m4, m4/msdos.m4, m4/next.m4: Newer autoconf
versions require stricter quoting.
2004-01-07 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* term/x11.trm (X11_args) [!USE_MOUSE]: Don't try to parse
"-nofeedback" option if mousing disabled.
* src/command.c (test_palette_subcommand, test_time_subcommand):
Made static; added missing local prototype.
(test_palette_subcommand): Changed static const int "colors" to an
enum to make it eligible as an array size under C90. Renamed to
"test_palette_colors" to avoid global name space contamination.
Made several local string constant variables 'static', and removed
a superfluous one. Reindented.
2004-01-06 Lars Hecking <lhecking@nmrc.ucc.ie>
* demo/Makefile.am.in: Add webify.pl to distribution.
2004-01-01 Ethan Merritt <merritt@u.washington.edu>
* configure.in: Fix incorrect nesting of libpdf status test.
2003-12-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/util3d.c (polyline3d_next): Bugfix. The patch on 2003-12-19
broke contouring in hidden3d mode. polyline3d_previous_vertex
wasn't updated.
2003-12-26 Jim Van Zandt <jrv@debian.org>
* src/set.c (load_tic_user): user tic definition can have 3rd
token specifying minitic
* src/axis.h: ticmark.level specifies major or minitic
* src/axis.c (gen_tics): Request user-supplied minitics
* docs/gnuplot.doc: document user-supplied minitics
2003-12-24 Ethan Merritt <merritt@u.washington.edu>
* src/show.c: Fix buffer overflow in conv_text() if the text
contains many characters with the high bit set.
* demo/enhancedtext.dem: Add demo for enhanced text mode.
* demo/charset.dem: Add demo that displays font and character
encoding.
2003-12-21 Ethan Merritt <merritt@u.washington.edu>
* term/post.trm src/gplt_x11.c src/set.c src/term_api.h
src/term.c: Add support for ISO-8859-15 character encoding.
* docs/gnuplot.doc: Minor changes to What's New.
2003-12-21 Petr Mikulik <mikulik@physics.muni.cz>
* term/x11.trm: Add missing #ifdef PIPE_IPC.
* term/pm.trm: Remove useless declaration.
2003-12-19 Ethan Merritt <merritt@u.washington.edu>
* term/svg.trm: Sodipodi didn't care that the namespace URL was
junk, but the Adobe svg viewer doesn't like this. Give it the real
URL.
2003-12-19 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/util3d.h (polyline3d_start, polyline3d_next): Prototypes
added.
* src/util3d.c (draw3d_line_unconditional): Avoid re-doing the
linetype change if it's to the same as in the lp_style_type
already applied.
(polyline3d_previous_vertex): New static variable.
(polyline3d_start, polyline3d_next): New functions. Draw connected
polylines in 3D. Hidden3d currently disables this --- to be added
in later. Polylines can't change colour in the middle of a run,
so palette mode turns this optimization off, too.
* src/graph3d.c (cntr3d_lines): Use new helper routines to draw
connected polyline instead of isolated segments.
(do_3dplot): Since cntr3d_linespoints would break polyline
handling, call cntr3d_lines() and cntr3d_points() in a row,
instead.
(cntr3d_linespoints): Now unused --> #if'ed out.
2003-12-16 Ethan Merritt <merritt@u.washington.edu>
* src/gplt_x11.c term/x11.trm: Add a new x11 command line option
-nofeedback, and the corresponding Xresource gnuplot*feedback. It
disables the feedback loop by which gnuplot_x11 reports font and
plot size information back to gnuplot via the mouse pipe. This is
a work-around for feedback synchronization problems triggered by
certain scripting environments and possibly by other causes under
os2.
2003-12-16 Petr Mikulik <mikulik@physics.muni.cz>
* docs/gnuplot.doc: Changes in "What is New in 4.0".
* src/mouse.c (bind_display): Minor change in the hotkey help.
* term/post.trm (START_HELP): Fixed undefined references in
gnuplot.tex.
* src/gplt_x11.c: #if (USE_MOUSE && MOUSE_ALL_WINDOWS) => #if
defined(...) && defined(...)
2003-12-15 Ethan Merritt <merritt@u.washington.edu>
* demo/Makefile.am.in demo/webify.pl demo/airfoil.dem
demo/prob2.dem: Integrate generation of demo web pages into the
Makefile, so that 'make html' autogenerates most of them. A few
oddball scripts need to be processed by hand.
2003-12-15 Ethan Merritt <merritt@u.washington.edu>
* term/svg.trm: Lauris Kaplinski <lauris@users.sourceforge.net>
diagnosed that the reason gnuplot point styles were not displaying
properly in some svg applications was our failure to specify the
xlink: namespace.
* term/post.trm: PS_filled_polygon() must flush current path on
entry if there is one. This fixes the missing arrow-shaft
problems seen in arrowstyle.dem. It is possible that the awk
scripts in pm3d/contrib need to be modified to parse the resulting
"stroke" command.
