07/Oct/99 Yorick/yio.c, Gist/ps.c fixes signed char errors so, e.g.- "\305" isn't parsed as "\37777777705" 28/Apr/99 Yorick/sysdep.c, several others replaced __setfpucw in attempt to cope with Debian potato problem 21/Jan/99 Yorick/array.c fixed bug in SetupVD that caused (lack of) bounds overreach error 11/Dec/98 Gist/tick.c fixed bug that caused plg,1+1.e-15*random(10) to core dump 10/Nov/98 Yorick/sysdep.c workaround bug in Linux libc6 that causes SIGINT to be blocked after first delivery 10/Nov/98 Yorick/MathC rewritten to make consistent with standard CBLAS, so vendor supplied BLAS libraries can be used. see Yorick/MathC/Makefile 10/Sep/98 Yorick/task.c Change to CheckForTasks/YMainLoop requested by Conrad Steenberg; should have no visible consequences 1/Sep/98 Gist/xbasic.c Fixed bug that caused completely clipped rotated text to blow up. 21/Jul/98 Yorick/ascio.c Fixed read, rdline so they won't try to seek a FIFO (or a pipe). 17/Jun/98 Browser/cgmin.c,main.c Modified cgmin so it can read NCAR ncgm files directly. 10/Apr/98 Gist/xbasic.h,xbasic.c,xicky.h,xicky.c Improved rotated text algorithm after studying xfig source code. Decent performance now, and opaque=0 rotated text works (the trick is to use XFillRectangle with fill style set to FillStipple or FillOpaqueStipple to render the text - working with bitmaps also avoids X{Get,Put}Pixel as well). This seems to fix the problem with rotated text sometimes drawing an inchoate blob, although I never understood why that happened. 25/Mar/98 Gist/tick.c,xfancy.c some multiple coordinate system bug fixes (thanks to David Syer) 20/Mar/98 Gist/xfont.c fixed bug in 75<->100 dpi font substitution (thanks to John Castor) 03/Mar/98 Gist/tick.c fixed bug with base60 (or degrees or hhmm) ticks 30/Jan/98 Yorick/binio.h, configure.in, configure fixed double alignment problem for Pentium machines -- improves performance on fft and matrix operations by a factor of order 2 26/Jan/98 Yorick/parse.c fixed egregious bug in YpLabel/YpGoTo that prevented more than one forward reference in goto statements to any single statement label 21/Jan/98 Gist/ps.c Fixed bug in !] escape sequence hack. 02/Jan/98 Gist/gcntr.c Fixed bug in data_init that caused problems with plfc for chunked meshes. (Gave GcTrace failed error message.) May only have happened with non-trivial ireg existence map. 20/Nov/97 MathC/* prefixed all blas routine names with y so that they can't collide with real blas routines -- perhaps should do this with all lapack names as well 7/Nov/97 Created a new yorick-1.4.diff.gz, see below for use. Yorick/ascio.c tried yet again to get formatted reads correct, should handle trailing fixed strings correctly now, hopefully nothing broken in the process of fixing that 16/Oct/97 Created a new yorick-1.4.diff.gz, see below for use. Yorick/fortrn.c (not used by yorick, for libyor.a only) fixed egregious bug in YAsyncFree 14/Oct/97 Created a new yorick-1.4.diff.gz, see below for use. Yorick/nonc.c fixed egregious bug in PowZL, try 1i^3 Gist/xicky.c removed WMHints that cause fvwm to pop up windows at (0,0) also made input hint togglable Yorick/graph.c, graph.i New keybd_focus function to turn off the X WM input hint, so window managers will not (we hope) offer keyboard focus to graphics windows 7/Oct/97 Created a new yorick-1.4.diff.gz, see below for use. Yorick/bcast.c Added gather and scatter virtual functions for specific data types huge performance increase on Crays, noticable improvement elsewhere Yorick/include/netcdf.i fixes suggested by R. Saravanan at UCAR Yorick/sysdep.c alternative for Solaris SIGFPE stuff which doesn't use libsunmath (not in configuation script yet) also minor change to NeXT branch to deliver other FPEs 19/Aug/97 Created a new yorick-1.4.diff.gz, see below for use. Yorick/parse.c Fixed another major bug with matrix multiply, which has always had wrong precedence relative to unary -. 14/Aug/97 Created a new yorick-1.4.diff.gz, create good source tree with: gzip -dc yorick-1.4.tar.gz | tar xvf - gzip -dc yorick-1.4.diff.gz | patch -N -p0 New bug fixes: (1) Yorick/ops.c Major bug (since yorick-1.3??) in matrix multiply repaired. Description: There are up to four spectator indices in a general matrix multiply: r=a(,+,)*b(,+,), with 4D result r(i,j,k,l). The problem occurred when (a) dimension i had unit length (or didn't exist, as in a(+,)*b(,+,)), and (b) index l did *not* have unit length. (2) Gist/draw0.c Fixed a problem with rotated text. There appear to be others. (3) Yorick/include/digit2.i Fixed digit2, interp2 to work with scalar x0,y0. (4) Yorick/include/pl3d.i, Yorick/include/slice3.i Work in progress. (5) Yorick/include/testp.i Made matrix multiply tests more (fully?) exhaustive. (6) Yorick/std.i Fixed im_part function so it actually works. 26/June/97 Patch file yorick-1.4.diff.gz can be applied to yorick-1.4.tar.gz distribution to fix all known bugs. Other than the ps.ps and ascio.c bugs noted below, these are minor. I will try to keep this patch file close to current. To apply it, you need to get the patch program, which is available from ftp://prep.ai.mit.edu/pub/gnu if you don't already have it. To use it, do something like this: gzip -dc yorick-1.4.tar.gz | tar xvf - gzip -dc yorick-1.4.diff.gz | patch -N -p0 8/Apr/97 Major bug in Gist/ps.ps (and pscom.ps); lines 43-46 now read: /DSHpat [ [ ] [ 82.5 ] [ 4.5 61.5 ] [ 82.5 39.0 4.5 39.0 ] [ 82.5 39.0 4.5 39.0 4.5 39.0 ] ] def /DSH { % index DSH DSHpat exch get replace them with: /DSH { % index DSH [ [ ] [ 82.5 ] [ 4.5 61.5 ] [ 82.5 39.0 4.5 39.0 ] [ 82.5 39.0 4.5 39.0 4.5 39.0 ] ] exch get If you have an installed Yorick, you only need to do this in Y_SITE+"gist/ps.ps" (type that in yorick). If you can't change the public ps.ps file at your site, you can put a correct version in ~/Gist/ps.ps until your maitainer can fix the public version. Without this, dashed and dotted thick lines will be broken in Yorick PostScript output. The correct ps.ps is available at ftp://ftp-icf.llnl.gov/pub/Yorick/ps.ps.gz. 4/Apr/97 Yorick/ascio.c line 1005 (2nd line of retry_sscanf) should read: int n= i? *pn : 0; (No patch file.) This causes SIGSEGV with high probability if you try a read or sread on floating point numbers in which there is an immediate matching failure, e.g.- x=[0.];sread("a1",x) 5/Mar/97 yorick-1.4 changed a few .i files for Langer -- this is the baseline version for the 1.3-level Mac and Windows ports to avoid confusion with all the patched 1.3 versions My plan is to resist any patches or bug fixes to 1.4, and begin work on the next round of major changes to be called 2.0. The 2.0 version will certainly include the following features: (1) Fully event driven. Complete input lines will be events on par with mouse events. This will drastically simplify interfacing Yorick to Windows/Mac or Java environments. Allow interpreted callbacks to service events. (2) Filename and directory support for non-UNIX environments. Handle slashes, backslashes, colons, and other idiocy better. (3) Rework the aging Gist package completely to reflect the lessons learned from the original. Biggest problems are event handling (mouse and keyboard) and many infelicities and unnecessary complexities in the coding. (4) Rework the binary file interface to cope with the new HDF and netCDF formats currently under construction. (5) If possible, repair the x()=a bug when x is scalar, and work on improving array indexing performance. Make it easy to extract diagonal array elements in multidimensional arrays. If I can get help, I would also like to merge the Windows and Mac ports into the mainstream distribution. Is the Java JNI a way to do that? Or wxWindows? Or something else? 27/Feb/97 fix Yorick/std0.c for [] args to atan, abs, min, max 26/Feb/97 fixed bugs in make.i 20/Feb/97 fixed overreach bug in Gist/gcntr.c:data_init (plfc function) 6/Feb/97 yorick-1.3-patch-6 fixed line buffer overrun in Gist/ps.c bumps version to 1.3e (sigh) ftp-icf.llnl.gov:/pub/munro/yorick-1.3e.tgz is the release 1.3 with patch-[123456] applied (version 1.3e) 4/Feb/97 fixed Browser/cgmin.c bug to allow more than 512 pages/file 3/Feb/97 yorick-1.3-patch-5 fix Gist/draw.c and Gist/draw0.c mesh-with-ireg scanning bumps version to 1.3d (sigh) ftp-icf.llnl.gov:/pub/munro/yorick-1.3d.tgz is the release 1.3 with patch-[12345] applied (version 1.3d) 21/Jan/97 fix Gist/xbasic.c bug involving zero length strings in plt 15/Jan/97 yorick-1.3-patch-4.gz fixes %% bug in format= for write bumps version to 1.3c (sigh) ftp-icf.llnl.gov:/pub/munro/yorick-1.3c.tgz is the release 1.3 with patch-[1234] applied (version 1.3c) 14/Jan/97 yorick-1.3-patch-3.gz fixes Gist/ps*.ps to work around PostScript search function bug fixes Drat/track.c to track through bowtied zones properly bumps version to 1.3b (sigh) 10/Jan/97 yorick-1.3-patch-2.gz fixes Yorick/graph.c plc, plv automatic scaling for meshes with logical holes fixes plmk to work on log scales cosmetic changes to Makefiles to help with Debian Linux bumps version to 1.3a (sigh) 26/Dec/96 yorick-1.3-patch-1 fixes MathC/dgblas.c so that LUrcond works (see bullet 5 below) don't know if any other LU, QR, or SVD routines affected ------------------------------------------------------------------------ Here are some of the bug fixes and new features of Yorick 1.3. There are some pretty major changes here. (0) Major bugs in X window error handling and color allocation fixed. Yorick should now run on DEC alpha consoles (1.2 usually died -- it could run on the alpha as long as DISPLAY was elsewhere). (1) Yorick/Gist now handles 90 degree rotated text! Thanks to Phil Rasch of NCAR for pushing me to provide this. The old path= keyword is defunct. Phil also supplied the plclab.i file, which puts numeric labels on contour curves. (Anyone who used the old path= keyword to plt and wants to keep using that style should read the new txpath.i file for help.) Furthermore, escape sequences for superscripts, subscripts, and special symbols are now recognized; see help on the plt function for more. Thanks to Roland Walter. (2) Yorick can now query and change the minutest graphics style parameters without recourse to style sheets. See style.i file. (3) Many bugs fixed in text I/O and parser (latter are workarounds for libc bugs on various platforms). One new feature: Yorick read now handles 1.234D56 Fortran-style numbers. A script f77dfix to repair this sort of output is provided as an alternative. (4) Bugs in binary I/O fixed. The netcdf.i package works much better in particular. (5) I reworked the C-BLAS subroutines, giving about a 20% performance improvement for matrix operations on most platforms. Several of the intrinsic Yorick functions have been similarly reworked (in particular, simple copy operations like y=x are faster now.) (6) The LUsolve routine now handles complex matrices directly. (7) pnm.i reads and writes PBMPlus-format portable bitmap files. (8) The Yorick manual has a new chapter on graphics. (9) The new contour function and modifications to the plfp function allowed new user-level graphics functions plfc and plmk, which color the regions between contours and draw polymarkers with user-definable shapes respectively. (10) The mesh_loc function is dramatically faster. A new digit2.i library file provides 2D versions of the digitize and interp functions (the latter is the oft-requested bilinear interpolator). (11) Some functions were added to the pl3d.i package to handle limits for arbitrary wire frame plots (plwf.i) and to draw unintelligible labeled tickmarks like other 3D graphics packages (at least no one can say Yorick can't plot 3D axes any more). Yorick 1.3 includes the optional MPY package. This is a multi-processing version of Yorick (Message Passing Yorick) based on the MPI standard. You need to have an MPI library and development system in order to build MPY. See the file MPY/README in the distribution. Yorick 1.3 includes an optional rlterm terminal emulator package. To build this, you need to get and build the readline package from project GNU first. See rlterm/README for instructions. If you are using an underpowered terminal emulator which cannot recall previous input lines (e.g.- xterm), rlterm may interest you. Yorick (and other command line based programs) are much easier to use if you can recall and edit previous input lines. Adding custom compiled routines is different under Yorick 1.3. You will need to simplify any pre-1.3 Makefiles: all you need to do is replace the exec_prefix and Y_HOME definitions at the top of the file with the new MAKE_TEMPLATE definition, and slice off the bottom half of the file (where the big cut mark is), replacing it by include $(MAKE_TEMPLATE) -- see MathC/Makefile or Drat/Makefile for examples. You may also want to add the new special MAKE-INSTRUCTIONS comments at the top of your startup .i files. Again, see Drat/drat.i or MathC/fft.i. If you do that, then the new make.i library can be used to automatically generate Yorick Makefiles. The directory layout Yorick wants to install to has changed again. Reread the top level README for details. ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------ Yorick 1.2 adds the functions catch, set_idler, and _lst and an associated set of linked list handling functions. Also, the sizeof operator now returns the length in bytes of a binary file, which is helpful for use with the _read function. The plotting function plfp, which plots a list of filled polygons, is also new. A minor change to the gridxy function allows full control over the ticks and labels without resorting to graphics style sheet files. This allows for "custom" tick marks and labels which cannot be generated by the automatic machinery. The combination of plfp and set_idler makes possible a basic 3D graphics interface, which is demonstrated by the new demo5.i include file. Start Yorick, include demo5.i and type demo5 to run the demonstration. If you like it, read demo5.i to lead you to the other relevant include files; the only documentation is via help DOCUMENT comments. As a general rule, expect to expend considerably more effort to make an intelligible 3D plot than, say, a 2D filled mesh (which requires more effort than an XY-plot) -- and don't complain to me that it's too hard! Other new include files (use the library function to print a complete list): legndr.i - Legendre polynomials, associated Legendre functions random.i - fancy random number generators fits.i - astronomical data FITS file interface string.i - handy functions for dealing with string data color.i - palette functions, including HSV<->RGB converters The combination of catch and set_idler makes possible Yorick extensions such as a simple message passing (multiprocessing) package based on the MPI standard. An alpha version of an MPI extension package, called MPY, may be available at ftp-icf and wuarchive. The Lisp-like lists correct the problem that Yorick pointers cannot point to some objects, such as file handles, functions, and bookmarks - which you sometimes need to keep in lists of indeterminate length. Lists are also far more efficient than the array grow function when the length of the list increases many times, since they are implemented as linked lists. The down side is that save and restore don't work for lists. ------------- Yorick 1.1 is not *very* different from 1.0. The main change is that shell-style comments (#) are no longer supported. If you have used them, I'm sorry -- switch your source to C++-style comments. I also changed the prompt so that dbug> appears only after you have really entered debug mode. I added three new demo programs, and a graphics test routine which can serve as a crude introduction to all of the graphics commands: grtest (in testg.i) -- crude graphics tutorial/shakedown demo2 (in demo2.i) -- movie of drumhead oscillations demo3 (in demo3.i) -- movie of chaotic pendulum demo4 (in demo4.i) -- movie of airfoil flow field There are also several new files in Yorick/include (use the library function to print the updated list): rkutta.i - Runge-Kutta integrator romberg.i - Romberg and Simpson integrators ellipse.i - complete elliptic integrals movie.i - aids to making animations Finally, there is now a Yorick mailing list. You can subscribe by sending "subscribe yorick" in the *body* of an e-mail message to: majordomo@lists.llnl.gov To post to the mailing list, send mail to yorick@llnl.gov. Please do *not* post things (such as installation questions or generic "I can't figure out how to...") to the mailing list -- instead, contact me at: munro@icf.llnl.gov Limit the mailing list to discussions of how you use Yorick, postings of generally useful Yorick functions, and the like.
