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.

- 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 portable ;-)

- 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:
- 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;
- the sparse matrix object can be used directly as a function to apply (possibly transpose) matrix multiplication;
- 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.
- *** 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:
- 2005-06-14:
- New morpho-math functions: morph_dilation, morph_erosion, morph_opening, morph_closing, morph_white_top_hat, and 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 returns a list of path separated by
':'into a single string whereas the former built-in Yeti version used to return an array of strings.
- *** POSSIBLE INCOMPATIBILITY ***
Built-in get_path removed (conflict with same
function in Yorick 1.6.02). The new get_path
function returns a list of path separated by
- 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 strlupper replaced by interpreted functions 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:
- new Yorick-1.6 now provides some regular expression engine (see strgrep);
- my regular expression package required the GNU REGEX library (part of 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 and is_vector.
- 2005-05-24: Yeti version 5.3.12 released.
- 2005-05-02:
- Changes in
yeti_plugin.c,yeti_misc.c,yeti_utils.candyeti.ito 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).
- Changes in
- 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.
- Fix bugs caused by using a nil string (e.g.
- 2005-02-02:
- Support for reloadable plugins.
- Complete rewrite of
configurescript. - 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 version 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 Clémentine Béchet 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 version 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 version 5.3.8 released.
- 2004-02-23: Added built-in function eigen to compute the spectral decomposition of real symetric matrices.
