Microsoft Office VBA code is usually held in binary format, making proper version control difficult. VBA Sync Tool synchronizes macros between a VBA-enabled file and a folder, enabling easy version control using any VCS.
VBA Sync Tool works *directly with the Office file,* unlike most other solutions, which use a host application (e.g., Excel) to manipulate the VBA code. This gives it several advantages: * Does not require special Excel settings. * Does not add to your VBA code base. * Allows you to use any off-the-shelf version control system. * Allows you to cherry-pick which modules to extract or publish. * Minimizes spurious changes by ignoring case on variable names, making merges easier. * Extracts full code including several hidden attributes. * Also extracts settings not tied to a particular module, like references. * Generates FRX files compatible with the VBE, but *without* any embedded timestamp. * Allows you to extract or publish a FRM module without necessarily updating its FRX module. * Works with document or worksheet modules in the same way as any other module. * Supports Excel 97-2003, Excel 2007+, Word 97-2003, Word 2007+, PowerPoint 2007+, and Outlook files. VBA Sync Tool has two modes: **Extract** mode extracts modules from the file into the folder. You can then commit the extracted files to version control. **Publish** mode publishes modules from the folder into the file. You should do this after merges.After you select a mode, a folder path, and a file path, the tool will list which modules have changed, with a checkbox next to each. Tick the checkbox next to each module with changes you'd like to apply. Double-click an entry to run a diff tool against the old and new files. (This requires setting up a diff tool under File→Settings.) If the underlying files change, click Refresh. When you're ready to synchronize, click Apply or OK.
You can save and load session settings from the File menu. Settings
are saved as .ini files. If a settings file is named VBASync.ini
and located in the working directory, VBA Sync Tool will load those
settings automatically. You can also specify a settings file on
the command-line. I recommend launching VBA Sync Tool from a shortcut,
to avoid having to specify the folder and file each time you need
to synchronize.
To build the tool, you will need to download
VBACompressionCodec.dll,
and drop it in the solution’s root directory.
