Grace list of changes


5.0.0 (since Xmgr-4.1.2):

New functionality

* [ES] T1 fonts are used for all devices using the T1lib library of Rainer Menzner. There should be no discrepancies anymore between characters displayed and printed (rep. #16) * [ES] routines of drawing layer rewritten from the scratch; Grace is now almost WYSIWYG, except patterns (rep. #184) * [EV] generic I/O filtering implemented (including rep. #240); see docs for details ! [ES] reciprocal axis scale implemented (rep. #33) * [EV] system-wide gracerc ($GRACE_HOME/gracerc) will be read at startup time, if exists ! [ES] overlined strings are possible (\o \O) (rep. #176). Doesn't work with device fonts yet ! [MM] extensions to regions including horizontal-inside, horizontal-outside, vertical-inside and vertical-outside ! [MM] Grace will use the FFTW library for Fourier transform if present on the system; see README.FFTW * [MM] negative indices in "Drop points" allowed (counting from the end of a set) * [EV] added a new feature to be extracted - the integral of each set ! [ES] "unit" and "const" added to the possible proctype's for modules. DEG (below) is an example what "unit" can be used for ! [ES] DEG and RAD are now meaningful. E.g., expressions like sin(90 deg) and sin(pi/2 rad) both are legitimate (and equivalent!) ("rad" can be omitted - it's there just for the sake of completeness) * [ES] metafile driver (not in final state) * [ES] PDF driver using the PDFlib of Thomas Merz; see README.PDF * [ES] GIF/GD driver using the GD library of Thomas Boutell (rep. #14); see README.GIF * [ES] logarithmic scales can have any base (rep. #370) * [ES] patterns and colors can be used simultaneously (rep. #291) * [ES] power tick label format changed to work in scientific format (rep. #361) * [ES] \B in composite strings will reset the font to the string's initial font (rep. #388) * [ES] PS/EPS driver rewritten from the scratch * [ES] X11 driver heavily rewritten

Interface

! [ES] removed "Plot/World scaling" popup ! [ES] re-designed axis props GUI popup (in particular, rep. #63, #313) * [EV] point ops popup fixes ! [ES] graph appearance props GUI popup ! [ES] removed "Viewport", "Frame", "Titles" and "Legends" popups. ! [ES] removed "Error bars" and "Edit legends" popups. ! [ES] re-designed set appearance props GUI popup (rep. #311, #369 should be fixed) * [EV] added expression evaluation to text input fields in all widgets * [EV] error window changed - only 1 window, not 1 window per error ! [EV] regression fits can be applied to specified interval and results are printed out in readable form * [EV] scrolled windows for explicitly requested expressions * [EV] canvas hotkeys added ! [ES] re-designed print setup GUI popup (problems in rep. #372, #412 should be fixed) * [ES] changing page size is possible for any device separately; the units can be "pix"els, "cm" or "in" (rep. #108, #211, #216, #405)

Project files

* [EV] background color saved * [MM] all regions, whether active or not, are saved to the file, so temporarily inactive regions don't get lost * [ES] page size is saved (rep. #312)

Parser

* [ES] cleaned grammar parser; instead of 350 shift/reduce and 231 reduce/reduce conflicts - > 61 & 0 respectively * [ES] MAX() and MIN() renamed to MAXOF() and MINOF() ! [ES] removed DX, DY, IMAGE ! [ES] removed GRAPHNO *BAR SIZE NUMBER ! [ES] removed SETNUM = SETNUM etc ! [ES] removed CMAP, STATUS, STATUSBAR, TOOLBAR, LOCATORBAR, LOCATOR

Defaults

! [ES] default page layout changed from free to fixed * [ES] \+ increases font size sqrt(sqrt(2)) times; \- respectively, decreases. Sub/superscripts are 1/sqrt(2) of the preceeding font size

Portability

* [AM] implemented dynamic modules for OS/2 * [EV] popen() for VMS * [JH/RN] VMS fixes * [AM] OS/2 updates

Misc

! [ES] removed (broke) xwd image loading ! [ES] removed all app-defaults not specific to GUI ! [ES] \x and \b control sequences removed

Bug fixes

* [ES] "-mono" command line flag now works * [EV] "-wd" command line flag fixed * [EV] trying to create a new set preceded with soft kill of all sets caused crash (rep. #367) * [MM] FFT fixes * [MM] when regions were read in from a saved file, they ended up linked to all graphs * [MM] in saved projects, REGNUM TRUE was used instead of REGNUM ON * [EV] several sets can be linked to the same file as in xny data (rep. #269) * [ES] crash on mono X servers fixed (rep. #285) * [ES] canvas refresh (rep. #217, #271 #317, #333, #375) * [ES] axis labels were not displayed if `display tick marks' wasn't selected (rep. #3) * [ES] coordinates of legend frame now corresponds to the left upper corner of the frame (rep. #31) * [ES] ticklabel format was reset by autoscale (rep. #119, #144) * [ES] bounding box of EPS was calculated only approximately (rep. #123, #145) * [ES] legend frame didn't account for sub/superscripts (rep. #189) * [ES] extraneous logarithmic tick marks were drawn in some cases (rep. #193) * [ES] accentuated titles weren't centered correctly (rep. #195) * [ES] switch to log scale with an axis containing zero might cause error messages infinitely looped (rep. #210) * [ES] filling of legend frame didn't work unless one turned the frame on (rep. #215) * [ES] the axes tick marks were behind set curves (rep. #224) * [ES] popup positioning left up to WM for all windows (rep. #273) * [ES] if graph contained too many ticks, autoscale was applied instead of tick position recalculation (rep. #275) * [EV] in "Point ops", 'Delete' ignored set number (rep. #293) * [ES] once activated, legends fill frame couldn't be switched off from within GUI (rep. #326) * [CM] adding legends to plots with number of data sets exceeding the default maximum caused a crash (rep. #344) * [ES] arranging or rearranging graphs by means of the "arrange" dialog reset previously set tick properties to defaults (rep. #356) * [ES] user tick labels w/subscripts did not show up in PS output (rep. #383) * [ES] FFT command didn't work correctly in parser (rep. #398) * [HS] command line parsing was wrong in several places (rep. #400) * [ES] misc. small fixes (including rep. #289, #406, #287)

5.0.1

New functionality
