2001-03-07 Johannes Zellner <[email protected]>

* src/pm3d.c: code cleanup

* src/plot3d.c: included stdfn.h so that HUGE is defined

2001-03-02 Hans-Bernhard Broeker <[email protected]>

* src/term.h [HAVE_LIBPNG]: Include new PDF terminal driver.

2001-03-01 Hans-Bernhard Broeker <[email protected]>

* term/pdf.trm: New terminal driver for Adobe PDF (Portable

Document Format) files.

* configure.in: Added detection code for PDFLib library, needed

to compile term/pdf.trm.

2001-02-28 Hans-Bernhard Broeker <[email protected]>

* src/term_api.h (DEFAULT_LP_STYLE_TYPE): New macro, to help

initializing lp_style_type struct variables directly.

* src/gadgets.c (DEFAULT_BORDER_LP): New macro to hold the default

lp_style_type for the graph border.

(default_border_lp): New global constant variable. Used to

re-initialize the border linetype by struct assignment.

* src/gadgets.h: Declaration for default_border_lp added.

* src/unset.c (reset_command): Assign border_lp from

default_border_lp instead of calling set_lp_properties().

* src/set.c (set_arrow, set_linestyle): Initialize local variable

from new macro DEFAULT_LP_STYLE_TYPE instead of calling

reset_lp_properties().

(set_border): Assign border_lp from default_border_lp instead of

calling set_lp_properties().

(reset_lp_properties, set_lp_properties): Functions no longer

used. Removed them.

* src/setshow.h (set_lp_properties): Removed prototype.

2001-02-28 Hans-Bernhard Broeker <[email protected]>

* term/emf.trm (EMF_text, EMF_reset): Reset emf_graphics flag to

FALSE to fix bug reported by J.Bollinger.

* term/emf.trm (EMF_STOCK_OBJECT_FLAG,

EMF_STOCK_OBJECT_WHITE_BRUSH, EMF_STOCK_OBJECT_BLACK_PEN,

EMF_STOCK_OBJECT_DEFAULT_FONT): New mnemonic macros to replace

magic numbers.

(EMF_setfont, EMF_text, EMF_dashtype): Use them.

* src/win/wgraph.c (LoadCursors): Use default cursor IDC_CROSS

instead of home-grown ptrcross.cur.

(CopyPrint): Codestyle: indented and commented #if/#else/#endif

lines.

* src/win/ptrcross.cur: File removed.

* src/win/wgnuplib.rc: Reference to ptrcross.cur deleted.

* src/win/wresourc.h (IDC_SCALING): Removed #define for

IDC_CROSSHAIR

* src/win/scaling.cur, src/win/rotating.cur: Binary files replaced

by new, much nicer versions.

* src/set.c (set_terminal): Codestyle: call gp_strdup() instead of

strdup().

* src/readline.h: The readline_ipc() prototype is now here, since

the functions is in readline.c, too.

* src/ipc.h: Moved readline_ipc() prototype away from here.

* src/command.c (com_line): Codestyle: #if's indented and

commented.

2001-02-27 Petr Mikulik <[email protected]>

* config/makefile.mgw: added a configuration section for easier setup

of compilation options.

2001-02-23 Hans-Bernhard Broeker <[email protected]>

* src/syscfg.h: Removed section defining VERYLARGE.

* src/stdfn.h: Moved blurb to define VERYLARGE macro from syscfg.h

to here. It needs <float.h> to have been included before it can do

its own part. Fixes endless loop bug in timefmt axes with a "set

xtics <incr>" type of tic placement lacking fixed endpoints.

2001-02-21 Petr Mikulik <[email protected]>

* src/win/wgraph.c: call GE_plotdone when graph drawn (otherwise

rotate-and-scale-by-mouse was not working); fixed set cursor

positioning typo ('set mouse zoomjump').

2001-02-19 Hans-Bernhard Broeker <[email protected]>

* src/win/wgraph.c (ruler, zoombox): Gave anonymous structs a

name.

(zoombox): Added string pointers for texts to be shown at corners

of the rubberband rectangle while zooming.

(everywhere): Lots of prototypes for static functions

added. Flagged all internal functions as 'static'. Comments added

and cleaned up. Stylistic changes.

(GWOPMAX): Moved here, from wgnuplot.h; only used inside this

module.

(GraphOp, Graph_put_tmptext, Graph_set_clipboard): Turned string

argument into to LPCSTR, i.e. pointers to const char, in Windows

parlance.

(GraphEnd) [USE_MOUSE]: Don't call DrawRuler from here.

(MakePens): Removed code no longer needed since the PM3D stuff

forced dynamic pen creation.

(Wnd_GetTextSize): New function. Isolated fragment from

MakeFont(), for re-use by mouseing functions.

(MakeFonts): Call new Wnd_GetTextSize().

(MakeFonts): Use TRUE and FALSE instead of 1 and 0 to asssing

states of lpgw->rotate.

(DestroyCursors): Replaced missing implementation by single

'return;' statement: the function has nothing to do, as it turns

out.

(drawgraph): If 'hdc' is a handle of a Metafile, GetDeviceCaps()

reports wrong results, leading to monochrome-only clipboard

contents. Assume colored output unless 'color' element in LPGW is

FALSE, for Metafiles.

(Wnd_exec_event): Compute difference of GetMessageTime() results

from one call to the next, so we should be able to tell

doubleclicks from single ones. Removed now-pointless parameter

'par2'.

(WndGraphProc): Moved static variable last_modifier_mask up to

function scope. It has to be visible to from different message

handling cases.

(WndGraphProc) [USE_MOUSE + WM_KEYUP]: Handle key-up events of

modifier keys, too.

(WndGraphProc) [USE_MOUSE + WM_KEYDOWN]: <Shift> and <Ctrl>

checking repaired. I haven't tested <Alt> yet.

(WndGraphProc) [WM_COMMAND + USE_MOUSE]: Don't call DrawRuler()

from here.

(WndGraphProc) [WM_PAINT + USE_MOUSE]: Re-paint all mouse

decorations of the plotwindow here, directly after the call to

drawgraph() has overwritten window contents.

(Graph_put_tmptext): Implemented cases 1 and 2 of the 'where'

argument by strdup'ing the texts over into the zoombox struct.

Update by calling DrawZoombox() before and after that.

(Graph_set_clipboard): Implemented.

(Draw_XOR_Text): New function. Implements true XOR text output via

a temporary bitmap, and an XOR-ing BitBlt() operation.

(DisplayStatusLine): Replaced previous, half-cooked version by

call of Draw_XOR_Text(). Removed argument 'erase'.

(UpdateStatusLine) [ENABLE_STATUS_LINE_RESIZE]: Threw out all the

chunks of this #ifdef version. This should be implemented in the

gnuplot core, instead.

(DrawZoomBox): Added implementation of corner label strings for

the zoom box. Uses Draw_XOR_Text() twice for each two-line string.

Also found and implemented a way to draw the zoombox in dashed

lines --- actually: in 'linetype 0', which is normally used for

zeroaxes and gridlines.

* src/win/wgnuplib.h (WGNUPLOTVERSION): Internal protocol version

number bumped by 0.1, with timestamp of yesterday, for all the

mouseing stuff and some other change I made while being at it.

(all over the place): Comments added and cleaned up.

(GWOPMAX): Moved out of here, over to wgraph.c.

(struct GW): Removed unused elements numsolid, hbpen, hpen[] and

hsolidpen[].

(GraphOp, Graph_put_tmptext, Graph_set_clipboard): Prototype

updated.

* src/gpexecute.c: Changed all PIPE_IPC || WIN_IPC conditionals

into PIPE_IPC, only. Windows doesn't actually use the stack of

mouse events implemented by these hungs.

(gp_exec_event) [WIN_IPC]: A big FIXME comment regarding

separation issues between wgnuplot.dll and wgnuplot.exe.

* src/command.c (winsystem) [_Windows] : made local variable 'p' a

pointer to constant char. That's LPCSTR, in Windows jargon.

* src/color.h (filled_polygon_3dcoords): GPHUGE attribute

specifier added to prototype

* term/svg.trm (SVG_PathLimit): Prototype added.

2001-02-15 Hans-Bernhard Broeker <[email protected]>

* src/win/wtext.h: Added #include <stdarg.h> needed to declare

va_list for prototypes.

* src/win/wgraph.c: Bracketed all mouse-specific within #ifdef

USE_MOUSE, as they should be. Removed some remains of the old

'numsolid' stuff.

(Wnd_exec_event): Pass message timestamp to gp_exec_event(),

replacing the fourth input parameter.

(WndGraphProc) [WM_MOUSEMOVE]: Rewrite and uncomment the Cursor

shape call. Also for the section used regardless of 'set mouse

off'.

(WndGraphProc) [WM_CHAR]: moved all the "special" keys into a new

WM_KEYDOWN case --- they don't generate WM_CHAR messages.

(WndGraphProc) [WM_KEYDOWN]: have all keys immediately call

Wnd_exec_event, so the default action can fall through to the

default handler. Handled some open ends introduced by Petr.

(WndGraphProc) [WM_KEYDOWN]: Moved the modifier key status check

to before the individual keys, and translated it from OS/2 to

Windows API. Code #ifdef'ed out for now, because it doesn't work,

yet.

* src/win/ptrcross.cur, src/win/scaling.cur, src/win/rotating.cur:

New files.

* src/win/wgnuplib.rc: Added definition of new cursor resources

for interactive mousing by reference to files.

* src/mouse.c (event_buttonrelease): Fixed FPRINTF() debugging

call.

* src/graphics.c (plot_vectors): Removed GPHUGE attribute.

* src/dynarray.c (nextfrom_dynarray): Corrected position of GPHUGE

attribute of the returned type.

* src/dynarray.h (nextfrom_dynarray): Prototype updated.

* config/makefile.win (CFLAGS) [WIN32]: Added -DVFPRINTF,

-DWIN_IPC and -DUSE_MOUSE to the list of flags.

(CFLAGS, CAUXFLAGS) [!WIN32]: Added -DVFPRINTF.

(DLLOBJS): Added gpexecute.obj.

(wgnupl32.exe): Added gpexecute to list of input files.

(DLLCC): Added -DUSE_MOUSE and -DWIN_IPC

2001-02-15 Hans-Bernhard Broeker <[email protected]>

* src/axis.c (axis_position_zeroaxis): Fixed behaviour for

reversed axes if 0.0 is not inside the range.

* src/graphics.c (histeps_vertical, histeps_horizontal): Added

code to handle clipping lines on reversed axes. Renamed parameters

'xl' and 'yl' to 'cur_x' and 'cur_y', in order to avoid confusion

with 'x1' and 'y1'.

2001-02-14 Hans-Bernhard Broeker <[email protected]>

* src/plot2d.c (get_data): For BOXES plots, don't set z_axis of

the plot to x_axis. That element is only used for a marker, not

for an actual x value.

(store2d_point): If z_axis of current plot is unused (-1), simply

store 'width' argument as the z value, without any of the usual

processing by STORE_WITH_LOG_AND_UPDATE_RANGE.

(eval_plots): Catch plot styles that don't work for functions.

Prints a warning and reverts to 'with points'

* src/plot3d.c (eval_3dplots): Catch plot styles that don't work

for functions. Prints a warning and reverts to 'with points'

* src/set.c (set_command): In 'set function style' handler, check

that plot style is applicable to function plots. If it isn't,

issue an error message and keep previous value.

(set_style): dito, for 'set style function' handler.

2001-02-12 Hans-Bernhard Broeker <[email protected]>

* src/win/wtext.h (MyVFPrintF): Fix typo: missing semicolon after

prototype.

2001-02-10 Petr Mikulik <[email protected]>

* src/win/wgraph.c: two more calls to DrawRuler() to draw the ruler

after the graph window has been de-minimized or replotted by gnuplot

after 'replot' or 'plot ...'; added remapping of VK_ key codes to

gnuplot key codes GP_.

2001-02-09 Hans-Bernhard Broeker <[email protected]>

* src/term.c (term_set_output): add code to work around an MSDOS

bug: 'set output' to the already open file causes file system

corruption. Solved by closing the file before opening it again.

2001-02-09 Hans-Bernhard Broeker <[email protected]>

* src/win/wgraph.c (ruler, zoombox): struct element 'on' made

TBOOLEAN.

(hptrDefault and friends): Uncommented Petr's suggestion, changed

type.

(GetMousePosViewport and friends): Internal prototypes updated.

(all over the place): Removed commented-out code blocks dealing

with the 'numsolid' and dynamic pen creation changes, for good.

(all over the place): changed // comments to /* ... */

(LoadCursors): New function. Loads cursor images from the system

or the resource file so cursor can change shape as different mouse

operations take place.

(DestroyCursors): New function, not implemented yet. Unloads all

the cursors registered by LoadCursors, to free the resources.

(drawgraph): Removed mouse_hdc initialization.

(Wnd_exec_event): New function, may no longer be needed. A wrapper

around gp_exec_event that records mouse position before calling

it.

(Wnd_refresh_zoombox): New function, used to be a code block in

WndGraphProc().

(WndGraphProc): Mouse position querying moved to helper functions

Wnd_exec_event and Wnd_refresh_zoombox --- only do the query if

the result is needed. Put an #ifdef USE_MOUSE around the code

added by Petr.

(WndGraphProc) [WM_CREATE]: call LoadCursors().

(WndGraphProc) [WM_DESTORY]: call DestroyCursors().

(Graph_set_cursor): Added LPGW parameter, implemented by

translating OS/2 sample code into Windows API calls.

(Graph_set_ruler): dito.

(Graph_put_tmptext): dito --- but implementation not complete,

yet.

(Graph_set_clipboard): Added LPGW parameter. Not implemented, yet.

(GetMousePosViewport): Added LPGW parameter. Removed Macros

WIN_XMAX and WIN_YMAX: query lpgw instead. Removed debugging

fprintf() to file.

(DisplayStatusLine): Added LPGW parameter. Implementation

rewritten almost from scratch, needing a new TBOOLEAN flag 'erase'

because of Windows API limitations.

(UpdateStatusLine): Added LPGW parameter.

(DrawRuler): Added LPGW parameter, turned OS/2 code outline into

Windows API implementation.

(DrawZoomBox): dito.

* term/win.trm (WIN_put_tmptext): pass LPGW pointer to graphwin

struct as additional parameter.

(WIN_set_ruler): dito.

(WIN_set_cursor): dito.

(WIN_set_clipboard): dito.

* src/win/wresourc.h (IDC_CROSSHAIR, IDC_SCALING, IDC_ROTATINT):

added resource identifier macros for mouse cursors.

* src/win/wgnuplib.h: Updated prototypes of mouse functions.

2001-02-08 Hans-Bernhard Broeker <[email protected]>

Several cleanups suggested by reading an MSVC compilation logfile:

* term/win.trm: added prototype for WIN_filledbox, and spread

warning notices all over the places regarding integer size

mismatch between the unsigned ints passed into the terminal API

and the WORD parameter accepted by GraphOp().

* src/win/winmain.c (MyVFPrintF): add 'const' qualifier.

(MyFPrintF): dito.

(MyFPutS): dito.

* src/win/wtext.h (MyFWrite): added 'const' qualifier.

(MyPrintF): dito.

(MyFPutS): dito.

(MyVFPrintF): prototype added.

(vfprintf): #define added, points to MyVFPrintF.

* src/win/wgraph.c (GraphOp): added 'const' qualifier to 'str' argument.

* src/win/wgnuplib.h: dito.

* src/command.c (winsystem): add 'const' qualifier to argument.

2001-02-07 Hans-Bernhard Broeker <[email protected]>

* src/fit.c (fit_command): Bugfix for 2D fits with a fixed yrange.

Local copying of range endpoints over to zrange was not done.

2001-02-06 Petr Mikulik <[email protected]>

* src/win/wgraph.c src/win/wgnuplib.h term/win.trm: partial

implementation of mouse support for Windows. It should be finished

according to my notes in the source code and on stderr.

2001-02-05 Petr Mikulik <[email protected]>

* config/makefile.mgw, src/gpexecute.h, gpexecute.c, mousecmn.h,

src/win/wgraph.c: WIN_IPC, an IPC for Windows. Hotkeys in the

windows terminal are now working.

2001-02-01 Hans-Bernhard Broeker <[email protected]>

* src/*.c, term/*.trm: Fixed incorrect usage of <ctype.h> macros.

If you pass a char to any of those, you *have* to cast it to

(unsigned char). Not to (int), but really unsigned char. The only

exception would be ints holding the result of an fgetc() or

similar call, but those don't occur in gnuplot.

* CodeStyle: added a paragraph describing this rule.

2001-02-01 Hans-Bernhard Broeker <[email protected]>

* src/set.c (set_command): Fix incorrect c_token movement in 'set

xdata {time}'.

2001-01-30 Hans-Bernhard Broeker <[email protected]>

* src/show.c (show_command): Fix broken 'show ticslevel' and 'show

ticscale' commands (from Pieter-Tjerk de Boer).

2001-01-22 Hans-Bernhard Broeker <[email protected]>

I had a look across all usages of [safe_]strncpy(), and patched

several:

* src/fit.c (backup_file): Off-by-one error in use of safe_strncpy

fixed.

* src/gplt_x11.c (ErrorHandler): cast 'display' argument to void

to silence a compiler warning.

* src/command.c (replotrequest): Replace strncpy call by memcpy

iff the 'size' argument of strncpy was hand-tailored to the length

of the 'from' string. In that case, the result is exactly the

same as with memcpy, but strncpy is inherently slower.

* src/fit.c (error_ex): dito.

(splitpath): dito.

(setvar): dito.

* src/gplt_x11.c (record): dito.

* src/plot.c (gp_expand_tilde): dito.

* src/set.c (set_pm3d): dito.

* src/fit.c (fit_interrupt): Replace sprintf() call with

user-specified string by safe_strncpy, to avoid format string

vulnerability.

2001-01-22 Hans-Bernhard Broeker <[email protected]>

* src/contour.c (fuzzy_equal): Removed use of 'zero' as a fudge

term. Avoid division-by-zero in another way. This also removed the

need for the private ABS() macro in this source. Removed.

* src/axis.c (mant_exp): Added code to change results like 10.0e0

to the result got from sprintf: 1.0e1, for number very close, but

not equal to 10.0. Takes the mantissa format string as a new

argument, to decide how close 'very close' should be.

(mant_exp): Also try to avoid calls to the pow() function wherever

possible.

(mant_exp): Changed type of 'scientific' flag to TBOOLEAN.

(gprintf): Now stores exponent found as a byproduct when

mant_exp() is called for the mantissa, to avoid another call to

mant_exp() for the exponent alone, later. Shuffled some code

lines to build starting conditions for mat_exp() correctly.

CAVEAT: this only works well if the mantissa is output _before_

the exponent, or the mantissa format has zero digits of precision.

(gprintf): Moved some repeated code out of the individual cases of

the main switch statement to behind it.

(gprintf): Avoids division of negative integers: the result would

be platform-dependant!

(gen_tics): Repaired numerically silly condition that would remove

all inner tics for axes shorter than DBL_EPSILON, i.e. about

1e-16.

2001-01-18 Hans-Bernhard Broeker <[email protected]>

* src/graphics.c (boundary): fix rounding errors in multiplot

placement by adding 0.5 to ytop, ybot, xleft and xright initial

values.

2001-01-18 Hans-Bernhard Broeker <[email protected]>

* INSTALL [HP-UX 10.x]: change recommendations regarding GCC on

HP-UX 10.x and higher.

* src/graph3d.c (xtick_callback, ytick_callback, ztick_callback):

remove 'static' attribute to avoid bug in HP-UX assembler. This

was the root of the long-standing compilation problems with GCC on

HP-UX 10 and higher.

* src/graphics.c (widest2d_callback, xtick2d_callback): dito

(ytick2d_callback): dito.

2001-01-16 Hans-Bernhard Broeker <[email protected]>

* src/term.h: add testing of THREEDKIT macro before activating

VGAGL terminal driver.

* src/interpol.c (cp_approx_spline, cp_tridiag, do_cubic):

streamline checks for logscaling and AXIS_UNDO_LOG calls into

AXIS_DE_LOG_VALUE calls.

* src/plot2d.c (eval_plots): dito.

* src/axis.h (AXIS_INIT3D, AXIS_INIT2D, CHECK_REVERSE): new

macro-local variable 'this' for more readable coding.

(AXIS_INIT3D, AXIS_INIT2D): only calculate log_base element if

logscaling is active for that axis, to avoid SIGFPE.

* src/axis.c (gen_tics): use AXIS_UNDO_LOG instead of explicit

coding.

(axis_output_tics): fix multiline x-axis label positioning.

2001-01-16 Hans-Bernhard Broeker <[email protected]>

New PNG feature from <[email protected]>:

* term/png.trm (PNG_id, PNG_opts): new option 'picsize' added to

table.

(PNG_options): handle new case PNG_PICSIZE by resizing the

drawable area handled by the 'bitmap' module.

(PNG_options): add output of option picsize.

(PNG_graphics): use new variable output sizes instead of fixed

constants.

(PNG terminal docs): document new option 'picsize'

2001-01-16 Hans-Bernhard Broeker <[email protected]>

* src/win/wpause.c (PauseBox): Change window style of Pause window

to make it show up in the taskbar and have it pop up on top of all

others.

(PauseBox): Insert WaitMessage() call to reduce CPU load while

gnuplot waits for the user to click away the pause window.

* term/win.trm (WIN_filledbox): New function, implements 'clear'

command for this terminal. Added entry to terminal API definition.

* src/win/wgnuplib.h (W_filledbox): define new message number.

* src/win/wgraph.c (drawgraph): handle new message W_filledbox to

draw blanked-out box.

2001-01-11 Hans-Bernhard Broeker <[email protected]>

* src/graphics.c (apply_head_properties): make temps unsigned to

match arguments of map_position().

* term/svg.trm (SVG_point): add missing TERM_PUBLIC stamp to

definition.

2001-01-04 Johannes Zellner <[email protected]>

* src/pm3d.c, src/pm3d.h, src/color.c: corrected

a bug for drawing the pm3d colorbox correctly if

using 'set pm3d zrange'.

2001-01-03 Johannes Zellner <[email protected]>

* src/pm3d.c: repaired 'pm3d zrange' for the column patch

2001-01-03 Johannes Zellner <[email protected]>

* term/post.trm: PS_make_palette() made it working with

negative palette values R/G/B.

2000-12-26 Johannes Zellner <[email protected]>

* term/ggi.trm,configure.in: pm3d for ggi using the

ggi xmi library. new configure switches:

--with-ggi

--with-xmi

2000-12-21 Johannes Zellner <[email protected]>

* src/save.c, src/show.c: handled the enum PM3D_SURFACE

2000-12-21 Johannes Zellner <[email protected]>

* src/graphics.c, src/plot3d.c: repaired function plotting

with lt pal or pm3d

2000-12-21 Johannes Zellner <[email protected]>

* new syntax

splot 'a.dat' with pm3d

and the plots are plotted in the correct order.

2000-12-21 Hans-Bernhard Broeker <[email protected]>

* src/datafile.c (df_tokenise): recover the original exponent

letter after addempting parse of FORTRAN-style numbers. Fixes bug

in parsing time/date input like "01Dec2000".

2000-12-20 Johannes Zellner <[email protected]>

* src/gp_types.h, src/graph3d.c, src/graph3d.h, src/hidden3d.c,

src/plot3d.c, src/pm3d.c, src/pm3d.h, configure.in, docs/gnuplot.doc,

TODO:

pm3d column feature: when specifying 2 or 4 columns for splot, the

last column is used to specify the palette color for either pm3d

or 'linetype palette'.

As I'm not sure if this breaks any existing stuff, and as it is

a quick hack, I decided finally to create a new branch. This branch

will be kept up to date, I'll try to synch it with the MAIN trunk

frequently until it is merged back to MAIN.

2000-12-20 Hans-Bernhard Broeker <[email protected]>

Fix bugs reported by Theo Hopman:

* src/set.c (set_logscale): "set logscale yz" bug fixed.

* src/save.c (save_tics): xtics saveing fixed.

* src/graph3d.c (do_3dplot): change incrementation of linetype for

contour lines. Fixes off-by-one bug between key sample and actual

line.

* src/contour.c (calc_min_max): Don't logarithmize the ranges

another time.

2000-12-20 Petr Mikulik <[email protected]>

* src/term.c: fixed one missing 'postscript_gpoutfile = 0;' after

a term->reset.

2000-12-20 Petr Mikulik <[email protected]>

* term/pm.trm src/os2/gclient.c: support for filled boxes (added

PM_fillbox routine) --- it is used by the 'clear' command in multiplot

mode to clear the subfigure area.

2000-12-19 Hans-Bernhard Broeker <[email protected]>

* docs/gnuplot.doc: small change to docs about EEPIC driver

behaviour.

2000-12-18 Hans-Bernhard Broeker <[email protected]>

* term/eepic.trm: cleaned up some warnings and 'checkdoc' problems.

2000-12-18 Hans-Bernhard Broeker <[email protected]>

* docs/gnuplot.doc src/set.c src/term.c src/term.h src/term_api.h:

new commands 'set term push', 'set term pop' (in order to achieve

platform independent restoring of the terminal after printing, for

instance) --- see 'help set term'.

* src/gplt_x11.c: OS2_PIPE minor fixes.

2000-12-16 Johannes Zellner <[email protected]>

for 'matrix'-type splot datafiles. 'index' increases for every

blank or comment-only line, as both terminate mesh reading in

df_read_matrix().

headers to make gnuplot.texi 'TeXable' again.

2000-11-24 Petr Mikulik <[email protected]>

* configure.in config/makefile.os2 term/x11.trm src/gpexecute.h

src/ipc.h command.c gpexecute.c gplt_x11.c plot.c readline.c:

The patch introduces explicit #define directives for different types

of interprocess communication (gnupmdrv, gnuplot_x11 => gnuplot):

OS2_IPC ... the OS/2 shared memory + event semaphores approach,

PIPE_IPC ... communication by using bidirectional pipe.

In the current sources, there is a mixture of #ifdef USE_MOUSE,

#if[n]def OS2, or #if defined() && () ... This patch makes it clear

what code is for what kind of IPC, while #ifdef USE_MOUSE ... #endif

parts don't mix with IPC codes. Of course, USE_MOUSE requires either

IPC defined.

Now it should be easy to add any other IPC for whichever platform

with terminal independent from the main gnuplot executable which wants

to support mouse and hotkeys; or modify PIPE_IPC to work for it too.

For example, gnuplot + gnuplot_x11 compiles on OS/2 fine with PIPE_IPC

instead of OS2_IPC, just it does not work.
