Change startup so that '--interactive' does not always force '--no-line-editing' (bug #60696).
* interpreter.cc (interpreter::interpreter): Create temporary variable "forced_interactive"
that holds state from the const-declared variable "options". Check if forced interactive
option was given in conjunction with a session that is already interactive ("m_interactive").
If found, then reset the forced nature of session to false both in the application ("app_context")
and locally in the temporary variable "forced_interactive".

Many common cases have been implemented using the naming scheme `movXXX` where `XXX` is the function that will be applied. For example, the moving average over a dataset is `movmean`. New moving window functions: `movfun` `movslice` `movmad` `movmax` `movmean` `movmedian` `movmin` `movprod` `movstd` `movsum` `movvar` - The `fsolve` function has been tweaked to use larger step sizes when calculating the Jacobian of a function with finite differences. This leads to faster convergence. - The `ranks` function has been recoded for performance and is now 25X faster. In addition, it now supports a third argument that specifies how to resolve the ranking of tie values. - The function `randi` has been recoded to produce an unbiased (all results are equally likely) sample of integers. This may produce different results in existing code. If it is necessary to reproduce the exact random integer sequence as in previous versions use `ri = imin + floor ((imax - imin + 1) * rand ());` - The function `isdefinite` now returns `true` or `false` rather than `-1`, `0`, or `1`. To test for a positive semi-definite matrix (old output of `0`) check whether the following two conditions hold: `isdefinite (A) => 0` and `isdefinite (A + 5*TOL, TOL) => 1` - The `intmax`, `intmin`, and `flintmax` functions now accept a variable as input. Existing code to query the range of an existing variable can be simplified by removing the call to `class` that was previously required. For example defining the variable `x = int8 (3)` in the workspace, calls like `range = [ intmin(class(x)), intmax(class(x)) ]` can in Octave 5 be simplified to `range = [ intmin(x), intmax(x) ]`. - The path handling functions no longer perform variable or brace expansion on path elements and Octave's load-path is no longer subject to these expansions. - A new printing device is available, `"-ddumb"`, which produces ASCII art for plots. This device is only available with the gnuplot toolkit. - The `msgbox` function has changed in two respects: the default WindowStyle is now `"non-modal"`, and the default interpreter for the message is now `"tex"`. Both WindowStyle and Interpreter can be controlled by passing an option struct argument. ### Dependencies - The GUI requires Qt libraries. The minimum Qt4 version supported is Qt4.8. Qt5 of any version is preferred. - The OSMesa library is no longer used. To print invisible figures when using OpenGL graphics, the Qt `QOFFSCREENSURFACE` feature must be available and you must use the qt graphics toolkit. - The FFTW library is now required to perform FFT calculations. The FFTPACK sources have been removed from Octave. ### Matlab compatibility - The determination of an object's dimensions, size, and shape by the functions `ndims`, `rows`, `columns`, `isscalar`, `isvector`, `isrow`, `iscolumn`, `ismatrix`, and `issquare` now fully depends on the function size. Thus, any user-defined object can ensure correct treatment by the aforementioned functions by properly overloading the `size` function. - The functions `issymmetric` and `ishermitian` accept an option `"nonskew"` or `"skew"` to calculate the symmetric or skew-symmetric property of a matrix. Performance has also been increased. - The `issorted` function now uses a direction option of `"ascend"` or `"descend"`. Change all uses of `"ascending"` and `"descending"` in existing code to the new options. - The `strncmp` and `strncmpi` functions now return `true` if the two input strings match, even though the number of characters specified by `n` exceeds the string length. For Example: `strncmp ("abc", "abc", 100)` returns `true` in Octave 5 and `false` in older versions of Octave. - The `str2func` function no longer accepts a second `"global"` argument. This argument was typically used to allow functions that accept function names as arguments to avoid conflicts with subfunctions or nested functions. Instead, it's best to avoid this situation entirely and require users to pass function handles rather than function names. - Using `clear` with no arguments now removes only local variables from the current workspace. Global variables will no longer be visible, but they continue to exist in the global workspace and possibly other workspaces such as the base workspace. #### Nonlinear Equations Several default solver options have been changed to be Matlab compatible. This *may* result in existing code producing different results. - `fsolve` Option | New Default | Old Default ---------------|------------------|------------- `FinDiffType` | `"forward"` | `"central"` `MaxFunEvals` | `100*length(x0)` | `Inf` `TolFun` | `1e-6` | `1e-7` `TolX` | `1e-6` | `1e-7` `Updating` | `"off"` | `"on"` - `fminsearch` Option | New Default | Old Default ---------|-------------|------------ `TolFun` | `1e-7` | `1e-4` - `fminbnd` Option | New Default | Old Default ---------------|-------------|------------ `MaxFunEvals` | `500` | `Inf` `MaxIter` | `500` | `Inf` `TolX` | `1e-4` | `1e-8` - `fminunc` Option | New Default | Old Default ---------------|------------------|------------ `FinDiffType` | `"forward"` | `"central"` `MaxFunEvals` | `100*length(x0)` | `Inf` `TolX` | `1e-6` | `1e-7` `TolFun` | `1e-6` | `1e-7` #### Graphic objects - Figure graphic objects have a new property `"Number"` which is read-only and will return the handle (number) of the figure. However, if the property `"IntegerHandle"` has been set to `"off"` then the property will return an empty matrix `[]`. - Patch and surface graphic objects now use the `"FaceNormals"` property for flat lighting. - `"FaceNormals"` and `"VertexNormals"` for patch and surface graphic objects are now calculated only when necessary to improve graphics performance. In order for any normals to be calculated the `"FaceLighting"` property must be set to `"flat"` (FaceNormals) or `"gouraud"` (VertexNormals), **and** a light object must be present in the axes. - The `"Margin"` property of `text`-objects has a new default of `3` rather than `2`. - Printing to raster formats (bitmaps like PNG or JPEG) now uses an OpenGL-based method by default. The print options `"-opengl"` (raster) and `"-painters"` (vector) have been added ("qt" toolkit only). The figure property `"renderer"` specifies which renderer to use. When the property `"renderermode"` is `"auto"` Octave will select `"-opengl"` for a raster output format and `"-painters"` for a vector output format. - A new print option `"-RGBImage"` has been added which captures the pixels of a figure as an image. This is similar to screen capture tools, except that print formatting options can be used to, for example, change the resolution or display the image in black and white. - Two new print options for page-based formats (PDF, PostScript) have been added. The `"-fillpage"` option will stretch the plot to occupy the entire page with 0.25 inch margins all around. The `"-bestfit"` option will expand the plot to take up as much room as possible on the page without distorting the original aspect ratio of the plot. - Printing using the `"-dtiff"` output device will now create compressed images using LZW compression. To produce uncompressed images use the `"-dtiffn"` device. ### Legacy functions The following functions have been declared legacy functions which means they are obsolete and should not be used in any new code. Unlike deprecated functions, however, their removal from Octave has not yet been scheduled. Function | Replacement -----------------------|------------------ `findstr` | `strfind` `flipdim` | `flip` `isdir` | `isfolder` or `dir_in_loadpath` `isequalwithequalnans` | `isequaln` `isstr` | `ischar` `setstr` | `char` `strmatch` | `strncmp` or `strcmp` `strread` | `textscan` `textread` | `textscan` ### Deprecated functions and properties The following functions and graphics properties have been deprecated in Octave 5 and will be removed from Octave 7 (or whatever version is the second major release after 5): - Functions Function | Replacement -------------------------|------------------- `output_max_field_width` | `output_precision` `is_keyword` | `iskeyword` - Graphics properties Object | Property | Value -----------------|---------------|------------ `text` | `fontangle` | `"oblique"` `uibuttongroup` | `fontangle` | `"oblique"` `uicontrol` | `fontangle` | `"oblique"` `uipanel` | `fontangle` | `"oblique"` `uitable` | `fontangle` | `"oblique"` - Specifying `legend` position with a numeric argument is deprecated. Use a string argument instead. - The environment variable used by `mkoctfile` for linker flags is now `LDFLAGS` rather than `LFLAGS`. `LFLAGS` is deprecated, and a warning is emitted if is used, but it will continue to work. ### Removed functions and properties The following functions and properties were deprecated in Octave 4.2 and have been removed from Octave 5. - Functions Function | Replacement -----------------------|------------------ `bitmax` | `flintmax` `mahalanobis` | `mahal` in Octave Forge statistics pkg `md5sum` | `hash` `octave_config_info` | `__octave_config_info__` `onenormest` | `normest1` `sleep` | `pause` `usleep` | `pause` `wavread` | `audioread` `wavwrite` | `audiowrite` - Properties Object | Property | Value ------------|-------------------|--------- `axes` | `xaxislocation` | `"zero"` | `yaxislocation` | `"zero"` `hggroup` | `erasemode` | `image` | `erasemode` | `line` | `erasemode` | `patch` | `erasemode` | `patch` | `normalmode` | `surface` | `erasemode` | `surface` | `normalmode` | `text` | `erasemode` | ### Alphabetical list of new functions added in 5 - `clearvars` - `isfile` - `isfolder` - `matlab.lang.makeUniqueStrings` - `matlab.lang.makeValidName` - `movegui` - `movfun` - `movie` - `movmad` - `movmax` - `movmean` - `movmedian` - `movmin` - `movprod` - `movslice` - `movstd` - `movsum` - `movvar` - `openfig` - `ordeig` - `savefig` - `uitable` ### Old release news - [Octave 4.4.x](etc/NEWS.4) - [Octave 4.2.x](etc/NEWS.4) - [Octave 4.0.x](etc/NEWS.4) - [Octave 3.8.x](etc/NEWS.3) - [Octave 3.6.x](etc/NEWS.3) - [Octave 3.4.x](etc/NEWS.3) - [Octave 3.2.x](etc/NEWS.3) - [Octave 3.0.x](etc/NEWS.3) - [Octave 2.x](etc/NEWS.2) - [Octave 1.x](etc/NEWS.1)
