* YYYY-MM-DD: COMMENT
===============================================================================
* 2008-02-14: Yeti version 6.2.2 released.
* 2008-02-14:
- Fix functions: identof, is_scalar, is_vector, is_matrix,
is_integer, is_real, is_complex, is_string, and is_numerical
when argument is an L-value. Thanks to "sguieu" for
reporting this bug on Yorick forum at SourceForge.
- Functions mem_copy and mem_copy also fixed to prevent
this problem.
* 2007-12-26:
- Cleanup of code to manage dimension lists (restricted functions
to: yeti_reset_dimlist, yeti_grow_dimlist and
yeti_start_dimlist). Get rid of ynew_dim dependency which will
be soon removed from Yorick's core.
- Minor fix in window_geometry.
* 2007-11-29:
- Configuration script fixed to allow for spaces in path to Yorick
executable and modified to have defaults for FFTW/GSL/TIFF linker
flags (i.e. so that only --with-fftw is needed if FFTW is installed
in standard place).
* 2007-10-25:
- Function h_show now displays name of symbolic links.
* 2007-10-16:
- New function h_grow to grow contents of hash table members.
* 2007-07-27: Yeti version 6.2.2pre1 released.
* 2007-07-27:
- Script config.i, files config.h.in and Makefile.in updated to
account for version numbers in the form: MAJOR.MINOR.MICROSUFFIX.
- New "global" variable YETI_VERSION_SUFFIX.
* 2007-07-26:
- New "global" variables: YETI_VERSION_MAJOR, YETI_VERSION_MINOR
and YETI_VERSION_MICRO.
- New functions (rgl_roughness_*) for regularization based
on roughness with various norms and boundary conditions.
===============================================================================
* 2007-05-14: Yeti version 6.2.1 released.
* 2007-05-11:
- Configuration script fixed to work with Cygwin/MS-Windows and
to allow for compilation with Yorick CVS version.
- Yeti Hierarchical Data File (YHDF) can now store functions
and symbolic links (by their names).
* 2007-04-30:
- *** POSSIBLE INCOMPATIBILITY ***
Due to inconsistencies, the API for symbolic links has been
reworked. To create a symbolic link to a variable, the ambiguous
`link` function has been deleted in favor of
`symlink_to_variable` and `symlink_to_name`. The functions
`link_name`, `solve_link` and `is_link` have been renamed as
`name_of_symlink`, `value_of_symlink` and `is_symlink`
respectively.
===============================================================================
* 2007-04-24: Yeti version 6.2.0 released.
* 2007-04-24:
- Add rules to build and install documentation of Yeti
plugins in Yorick installation directory.
* 2007-04-19:
- The `symbol_names` function can now specifically select
lists, hash tables and/or auto-loaded functions.
- The `about` routine now account for auto-loaded functions.
- Bug in function `make_dimlist` fixed.
* 2007-03-23:
- Hash table objects can now have their own evaluator, which can be
queried/set by the `h_evaluator` function.
- New function `h_number` to query number of entries in a hash table.
- Function `is_hash` returns 2 for a hash table object implementing
its own evaluator.
- `h_clone`, `h_copy`, `h_info` and `h_show` fixed to account for the
evaluator of an hash table object.
- Restricted possible values for JOB/FLAGS in evaluation of
matrix products: must be 0 (default) for direct product and
1 for transpose product.
* 2007-01-26:
New interpreted function: `setup_package`.
* 2007-01-23:
New object type: symbolic link. New related functions: link,
is_link, link_name and solve_link.
===============================================================================
* 2006-12-17: Yeti version 6.1.7 released.
* 2006-12-01:
Renamed built-in `typeIDof` as `identof` and provide constants
for `T_CHAR`, `T_SHORT`, ...
===============================================================================
* 2006-07-19: Yeti version 6.1.6 released.
* 2006-07-19:
New builtin function `insure_temporary`.
* 2006-07-19:
New builtin function `quick_select`. New functions `quick_median`
and `quick_interquartile_range` for fast estimation of the median
and the inter-quartile range of an array of values.
===============================================================================
* 2006-06-10: Yeti version 6.1.5 released.
This is the first public release of Yeti which makes use of the new
Yorick API "YAPI" and which provides support for GSL (the GNU
Scientific Library).
* 2006-06-10:
- Documentation for Yeti-GSL completed.
- Fixed inconsistency in error computation for Yeti-GSL.
- New function h_show to display a hash table as an expanded tree.
* 2006-01-30:
- Built-in function is_list removed from Yeti (it is now part of
Yorick).
* 2005-12-08:
- New built-in functions: make_dimlist.
* 2005-12-01:
- New built-in functions: window_select, window_exists and window_list.
* 2005-11-18:
- Changed yeti_tiff plugin so that it uses new Yorick API "YAPI".
- In tiff_plugin, TIFF objects can now be indexed by their tag names.
* 2005-11-14:
- Changed yeti_gsl plugin so that it uses new Yorick API "YAPI".
* 2005-09-27:
- New plugin yeti_gsl which implements support for GNU Scientific
Library. At this time, the plugin provides 118 special functions
from the GSL.
- Fix bug in sparse_expand().
- In about() function, explicitely filter range operators which have
a built-in function counterpart to avoid a deadly bug in Yorick.
===============================================================================
* 2005-09-16: Yeti version 6.0.2 released.
* 2005-09-16: Use Yorick (instead of Bourne shell) for configuration of
Yeti -- much more easy and protable ;-)
* 2005-09-13: New built-in function 'machine_constant' to query machine
dependent constant (such as DBL_EPSILON).
* 2005-08-31: Fixed signedness of strings in yeti_hash.c to avoid
compiler warnings.
* 2005-08-11: Fixed bad variable name in morph_white_top_hat(),
and morph_black_top_hat.
===============================================================================
* 2005-07-30: Yeti version 6.0.0 released.
* 2005-07-19:
- New functions cost_l2(), cost_l2l1() and cost_l2l0() to compute,
L2, L2-L1 and L2-L0 cost functions and optionally their gradient.
* 2005-06-15:
- *** POSSIBLE INCOMPATIBILITY ***
The old sparse matrix API has been removed in favor of a new
sparse_matrix object class. The new class is different from
the old implementation: [1] it has two index lists (one for the
rows, the other for the columns of the non-zero coefficients) to
break the former limit on the dimension lists of input/output
spaces; [2] the sparse matrix object can be used directly as a
function to apply (possibly transpose) matrix multiplication; [3]
the sparse matrix object can be used as a Yorick structure to
query its contents.
- *** POSSIBLE INCOMPATIBILITY ***
The built-in function _yeti_init was renamed as yeti_init.
* 2005-06-14:
- New morpho-math functions: morph_dilation, morph_erosion,
morph_opening, morph_closing, morph_white_top_hat,
morph_black_top_hat.
* 2005-06-03:
- *** POSSIBLE INCOMPATIBILITY ***
Built-in get_path() removed (conflict with same function in
Yorick 1.6.02). The new get_path function return a list of
path separated by ':' into a single string whereas the
former version built-in Yeti used to return an array of strings.
* 2005-05-24:
- Lots of changes to make Yeti a pure plugin for Yorick 1.6 and
trying to maintain compatibility with previous version of Yeti.
- Temporarily removed all the chn_* function (channel).
- Builtin expand_path() removed in favor of filepath().
- Built-in strlower() and strlower() replaced by interpreted
version which use the new strcase() built-in function in
Yorick-1.6. Similarly, strtrim() removed because it is now
provided by Yorick-1.6 with same behaviour.
- "yeti_fftw" and "yeti_tiff" packages no longer require Yeti to
be loaded (they are pure standalone Yorick packages).
- Regular expression functions regmatch(), regsub(), regcomp(), etc
are now provided by a separate package "yeti_regex". Two reasons
for that: (1) new Yorick-1.6 now provides some regular expression
engine (see strgrep), and (2) my regular expression package
required the GNU REGEX library (built-in GNU C library). The GNU
REGEX library can be optionally built into the new "yeti_regex"
package (i.e. you no longer need an external REGEX library).
Also note that the "yeti_regex" does not require Yeti to be
loaded (it is a pure standalone Yorick package).
- New Built-in functions: is_complex, is_hash, is_integer, is_list,
is_matrix, is_numerical, is_real, is_scalar, is_string, is_vector.
===============================================================================
* 2005-05-24: yeti-5.3.12 released.
* 2005-05-02:
- Changes in 'yeti_plugin.c', 'yeti_misc.c', 'yeti_utils.c' and
'yeti.i' to avoid problems on 64-bit machines. A (minor) side
effect is that addresses in 'mem_*' hack functions must now be
long integer (i.e. int's are no longer allowed).
* 2005-04-14:
- Fix bugs caused by using a nil string (e.g. string(0)) as
hash key and which trigger segmentation violation interrupt
(SIGSEGV).
- New functions h_first and h_next to scan a hash table.
* 2005-02-02:
- Support for reloadable plugins.
- Complete rewrite of 'configure' script.
- CP40/GPL support is now provided as a separate plugin.
- Startup routine '_yeti_init' to provide a more useful list of
paths for script files (*.i) than the one setup by Yorick.
- Removed 'yeti_version' function in favor of '_yeti_init'
function and pre-defined variables YETI_VERSION and
YETI_HOME.
* 2004-10-14: New function "get_includes" to get a list of included files.
===============================================================================
* 2004-09-27: yeti-5.3.11 released.
* 2004-09-17: Fix a bug in "arc" and "round" built-in functions which
triggers when the argument was a non-double scalar (thanks to
Clmentine Bchet for finding this bug).
* 2004-09-16: "about" interpreted function can optionally ignore case.
* 2004-09-15: New interpreted function "h_clone" to clone/copy a hash object.
* 2004-09-15: Work around Yorick bug with palette in gg_fit_2d_spike.
===============================================================================
* 2004-09-09: yeti-5.3.10 released.
* 2004-09-09: Yeti now displays its version number which can be retrieved
by function yeti_version.
* 2004-09-09: New built-in function "current_include" to get the path
of the currently parsed file if any.
* 2004-03-12: New built-in function "arc" to compute lengh of arc in
radians.
* 2004-03-04: Fix built-in "heapsort" to always return a vector (as
claimed in the doc).
* 2004-03-03: Avoid Gist markers when drawing widgets in yeti_gist_gui.i.
* 2004-02-27: Hash table objects can be invoked as a function with a
member name (syntaxic shortcut for h_get) or with a nil argument
to get the number of elements.
===============================================================================
* 2004-02-23: yeti-5.3.8 released.
* 2004-02-23: Added built-in function "eigen" to compute the spectral
decomposition of real symetric matrices.
