373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	50 does not yet support text objects. Obviously, this is a necessary
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	51 feature before it can be considered usable. We are looking for
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	52 volunteers to help implement this missing feature.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	53

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	73 The following functions, which handled only sparse matrices have
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	74 been removed. Instead of calling these functions directly, you
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	75 should use the corresponding function without the "sp" prefix.

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	85 The interactive debugging features have been improved. Stopping
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	86 on statements with dbstop should work correctly now. Stepping
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	87 into and over functions, and stepping one statement at a time
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	88 (with dbstep) now works. Moving up and down the call stack with
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	89 dbup and dbdown now works. The dbstack function is now available
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	90 to print the current function call stack. The new dbquit function
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	91 is available to exit the debugging mode.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	92
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	93 ** Improved traceback error messages.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	94
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	95 Traceback error messages are much more concise and easier to
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	96 understand. They now display information about the function call
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	97 stack instead of the stack of all statements that were active at
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	98 the point of the error.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	99
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	100 ** Object Oriented Programming.

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	102 Octave now includes OOP features and the user can create their own
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	103 class objects and overloaded functions and operators. For
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	104 example, all methods of a class called "myclass" will be found in
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	105 a directory "@myclass" on the users path. The class specific
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	106 versions of functions and operators take precedence over the
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	107 generic versions of these functions.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	108
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	109 New functions related to OOP include

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	115 ** Parsing of Command-style Functions.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	116
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	117 Octave now parses command-style functions without needing to first
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	118 declare them with "mark_as_command". The rules for recognizing a
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	119 command-style function calls are
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	120
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	121 * A command must appear as the first word in a statement,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	122 followed by a space.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	123
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	124 * The first character after the space must not be '=' or '('
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	125
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	126 * The next token after the space must not look like a binary
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	127 operator.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	128
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	129 These rules should be mostly compatible with the way Matlab parses
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	130 command-style function calls and allow users to define commands in
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	131 .m files without having to mark them as commands.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	132
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	133 Note that previous versions of Octave allowed expressions like
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	134
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	135 x = load -text foo.dat
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	136
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	137 but an expression like this will now generate a parse error. In
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	138 order to assign the value returned by a function to a variable,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	139 you must use the normal function call syntax:
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	140
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	141 x = load ("-text", "foo.dat");
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	142
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	143 ** Block comments.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	144
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	145 Commented code can be between matching "#{" and "#}" or "%{" and
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	146 "%}" markers, even if the commented code spans several line. This
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	147 allows blocks code to be commented, without needing to comment
