Getting the Development Version of Carpet

About Darcs

The development version of Carpet is now managed in a darcs repository. Darcs has a number of advantages for us developers, such as:

• You have a local copy of the repository, and can therefore work offline
• You can decide which changes you want to import and export, so that you can omit dangerous changes, or keep changes to yourself until you are ready to publish them
• You can undo most changes
• You can easily rename files and directories
• Darcs does not need its own server, which makes it both more convenient and more secure

and them some more, as described in the darcs manual.

Getting Carpet

In order to get the development version of Carpet, you first need to install darcs on your system. This is described on the darcs home page, and some links to binaries are given in the darcs wiki. If you have problems installing or using darcs in general, then you should ask on the darcs mailing list, which I (Erik Schnetter) read regularly. We have also prepared a gzipped, statically linked version for Linux/i386, and the gzipped postscript documentation (260 kB) for it.

By the way, you can also have a look at Carpet's source tree in your web browser.

After installing darcs, take the following steps to get Carpet:

1. Move your old version of Carpet to a secure place:

   cd Cactus
   mkdir oldcarpet
   mv arrangements/Carpet* oldcarpet

2. Get the development version of Carpet. Carpet consists of four arrangements that live in a single repository. This structure is not what Cactus expects, and we will therefore put it outside the arrangements directory:

   cd Cactus
   darcs get http://www.carpetcode.org/~darcs/carpet

   This copies the whole Carpet repository, and it will take some time.
3. Create some symbolic links in the arrangements directory:

   cd Cactus/arrangements
   ln -s ../carpet/Carpet* .

   (don't forget the dot at the end of the last line).

That's it; you can now recompile your Cactus/Carpet configurations.

Updating Carpet

At some time you will want to update your version of Carpet and incorporate some changes from the main Carpet repository.

1. You do this with the command

   cd Cactus/carpet
   darcs pull

   which will look for new changes, and then ask you which of these you want to obtain. Normally, you will want all changes.

Working with Darcs

We also have some instructions on how to develop Carpet with darcs.
