A very simple add-in for Delphi and C++ Builder IDE's (a.k.a Borland Developer Studio, a.k.a Turbo Delphi/C++, a.k.a. CodeGear/Embarcadero RAD Studio).
This add-in is known to work at least up to RAD Studio / Delphi / C++ Builder 2010. Note that if you own a more recent version (RAD Studio / Delphi / C++ Builder XE*) you have integrated Subversion support, so you probably don't need this add-in.
This will add a menu with the most common TortoiseSVN commands to work with the current project files, like this one:
This add-in is just to facilitate working with TortoiseSVN without leaving the IDE. It's not meant to be a fully-IDE-integrated VCS system.
This is the TortoiseSVN menu integrated on Delphi 2010 IDE main menu:
This is the TortoiseSVN menu integrated on C++ Builder 5 IDE main menu:
TortoiseSVN must be installed. The add-in was tested with versions 1.3 through 1.6
Usage tips - known issues
The "update" and "revert" commands are a bit tricky. You may need to reload your editor files after you use them.
Binaries - installation
The add-in builds and installs as a Delphi package. There are no pre-built binaries; as there exist many versions of IDE's it's recommended that you create your own package for your particular environment.
It's also possible to build the add-in as a DLL (see the readme files for details).
Source code - compiling
The main source file is available here. You will also need this resource file. You just need to create a package project, add the main source file, build and install.
The add-in uses the "new" Open Tools API, so it compiles in Delphi 4 and above. It can be easily (at least I think so) converted to C++ and compiled in C++ Builder, if necessary.
Please check these notes if you stumble upon any issue.
The first add-in version (made with the "old" Open tools API) is still available just in case you want it. Check "src/oldOTA" in the file section. It is known to work in all Delphi versions up to 7.
Development of this add-in is closed. Source code is still available so you can add any SVN command you want, which should be pretty simple looking at existing ones.
