Action classes for specific applications

For specific tasks, that cannot be performed with simple actions (keystrokes), meta-actions or Unimacro Shorthand Commands, it now is possible to define an application specific actions class. With this action class actions can be done, like jumping to a line in a file, but also information from the application can be retrieved, like the line number the cursor is on.

Example: win32pad

The easiest example is win32pad, the notepad lookalike with line numbers. In the file win32pad-actions.py, in the actionclasses subdirectory of Unimacro, the class Win32padActions is defined.

The needed actions go through windows message functions (see page about global dictation, but also the module messagefunctions.py in the Unimacro directory. With these messages function, as called in the class MessageActions (found in actionbases.py), information about a window can be retrieved.

In the example the function getCurrentLineNumber is used to give the line number the cursor is on. This is used in the grammar _lines.py for doing line numbers modulo 100.

Example: ultra edit

The program uedit32, UltraEdit, which is not free software, does the same trick. Some more effort was needed here to find the foreground tab in this multitab IDE.

Example: komodo

With my favourite IDE, Komodo, also not free software, I did not succeed to implement a class that does the same trick. As Komodo can execute python programs, a dialogue via TCP-IP could be setup to retrieve the necessary information. This would be the same strategy as voicecode uses with Emacs.

Example: excel

Connection with Excel is made via a so-called COM object. One of the functions is again getCurrentLineNumber, so the grammar _lines.py can also here use the line numbers modulo hundred option.

Moreover via this class more information is retrieved from the Excel instance, like sheet names. The program specific grammar excel.py also use this this module to get and set information.

Usage: _lines.py

In the grammar _lines use of these functions is made as soon as a valid program specific actions module is found, as in the examples above. Then the grammar lines can use to current line number in order to perform a line number switch modulo 100, has also is established with Emacs through Vocola commands.

When the option line numbers modulo hundred is not set, this grammar this no attempts to get an instance of this program specific actions modules.

Usage: Excel

As described above, the grammar Excel can use this actions class excel-actions.py for doing several specific commands.

Implementation

care has been taken that the load for Unimacro is as little as possible. Therefore in the module actions.py in specific cases the program specific actions modules are instantiated, and the results are kept in a dictionary with the window handles as keys. This means that when an application is visited more often, the instance can be retrieved through this dictionary.

For details about the calling, please study the file _lines.py.
