Fix backslash handling in regexp pattern (Bug #37092) * NEWS: Give an example of how escape sequence processing in single-quoted regular expressions works. * libinterp/corefcn/regexp.cc(do_regexp_string_escapes): Rename to do_regexp_ptn_string_escapes. Only sequence to expand is '\b' for backspace. Others are handled by PCRE. * libinterp/corefcn/regexp.cc(do_regexp_rep_string_escapes): New function to do escape sequence processing for the replacement string since the sequences to expand differ from that of the regexp pattern. * liboctave/util/regexp.cc(regexp::replace): Process backslashes in replacement string so that '\$1' results in '$1' rather than replacement with first capture buffer.

4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	429 general-purpose binary searching. Using this improvement, the
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	430 ismember function was rewritten for significantly better

b59cc3252a51 NEWS update Jaroslav Hajek <highegg@gmail.com> parents: 9215 diff changeset	433 ** Real, integer and logical matrices, when used in indexing, will now
b59cc3252a51 NEWS update Jaroslav Hajek <highegg@gmail.com> parents: 9215 diff changeset	434 cache the internal index_vector value (zero-based indices) when
b59cc3252a51 NEWS update Jaroslav Hajek <highegg@gmail.com> parents: 9215 diff changeset	435 successfully used as indices, eliminating the conversion penalty for
10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	436 subsequent indexing by the same matrix. In particular, this means it
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	437 is no longer needed to avoid repeated indexing by logical arrays
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	438 using find for performance reasons.

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	440 ** Logical matrices are now treated more efficiently when used as
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	441 indices. Octave will keep the index as a logical mask unless the
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	442 ratio of true elements is small enough, using a specialized
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	443 code. Previously, all logical matrices were always first converted
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	444 to index vectors. This results in savings in both memory and
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	445 computing time.

4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	448 functions for better performance. These functions are now faster,
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	449 can deliver more economized results for ranges, and can reuse the
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	450 index cache mechanism described in previous paragraph.

4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	454 multiple arguments. This is especially useful for summing

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	468 ** The default behavior of `assert (observed, expected)' has been
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	469 relaxed to employ less strict checking that does not require the
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	470 internals of the values to match. This avoids previously valid
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	471 tests from breaking due to new internal classes introduced in future
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	472 Octave versions.

a35d8ec8a0c4 update NEWS Jaroslav Hajek <highegg@gmail.com> parents: 9408 diff changeset	474 For instance, all of these assertions were true in Octave 3.0.x
a35d8ec8a0c4 update NEWS Jaroslav Hajek <highegg@gmail.com> parents: 9408 diff changeset	475 but false in 3.2.x due to new optimizations and improvements:

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	481 ** The behavior of library functions `ismatrix', `issquare', and

10292 c1246f17119e update NEWS Jaroslav Hajek <highegg@gmail.com> parents: 10276 diff changeset	486 returned false if the first or second dimension was zero.
c1246f17119e update NEWS Jaroslav Hajek <highegg@gmail.com> parents: 10276 diff changeset	487 Hence, `ismatrix ([])' was false,
c1246f17119e update NEWS Jaroslav Hajek <highegg@gmail.com> parents: 10276 diff changeset	488 while `ismatrix (zeros (1,2,0))' was true.

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	490 * The `issquare' function now returns a logical scalar, and is

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	500 logical scalar is returned rather than the dimension, so
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	501 `issymmetric ([])' is now true.
