Converting from Arch
There are two different automatic conversion scripts to create a Darcs repository from an Arch repository: arch2darcs and tla2darcs. arch2darcs is newer and strives to have these improvements over tla2darcs:
- Handles renames properly
- Good support for importing a whole branch at once
- Less crash-prone
- Also useful for synching from arch to darcs later on
Please report feedback on either tool to the darcs-users list so we can update this page.
arch2darcs
Download arch2darcs with:
darcs get --partial http://darcs.complete.org/arch2darcs
Follow the installation instructions in the README file, http://darcs.complete.org/arch2darcs/README. arch2darcs can convert entire branches and maintain a Darcs mirror of an Arch repository. Here's an excerpt from the README illustrating the use of arch2darcs for the initial conversion of an Arch branch:
$ tla get jgoerzen@complete.org--projects/missingh--head--0.5--base-0 missingh
*** IMPORTANT NOTE: make sure you include "--base-0" from the above
command.
$ cd missingh
$ darcs initialize
$ arch2darcs -i
Processing existing Arch situation...
Looking for new patches...

Done.
tla2darcs
To migrate an Arch project to Darcs:
Download tla_import.pl and tla_convert_patch.pl from http://sacha.free.net.ph/notebook/darcs/dev/tla2darcs/
Check out your project using:
perl tla_import.pl [archive/]category--branch--version directory
Move into the directory you just created
cd directory
Apply patches either all at once or individually with
perl tla_convert_patch.pl [archive/]category--branch--version
or
perl tla_convert_patch.pl patch1 patch2 patch3 ...
Example:
perl tla_import.pl sacha@free.net.ph--main/planner--dev--1.0 planner
cd planner
perl ../tla_convert_patch.pl sacha@free.net.ph--main/planner--dev--1.0
Limitations:
- Does not handle conflicts well yet.
- Doesn't do anything reasonable with multiple branches.

I followed the directions and tla_convert_patch.pl seems to have bombed with this:
