Currently it supports these two address book storage backends: - ffcrm: a driver for Fat Free CRM, an open source CRM (customer relationship management) tool written using Ruby on Rails - mapi: a driver for MAPI (Messaging API), Microsoft's standardized addressbook engine for Windows. This has been tested with Exchange 2003, but probably works with other versions of Exchange, your personal Outlook contact list, and maybe even other MAPI-compliant servers like Lotus Notes. It's relatively easy to add a new backend; look in cmd/ffcrm.py or cmd/mapi.py for examples. Quick start ----------- WARNING!! BACK UP YOUR DATABASES AND CONTACTS FOLDERS FIRST!!

It's safe to merge in both directions as many times as you want. But watch out!! Be sure to make a backup of all your databases / folders before you mess with them. Crampi has the potential to make a terrible mess if you use it wrong or if it has bugs. And this is an early version, so it surely has bugs. How it works ------------ Crampi's core data structure is a central sqlite3 "repository" called crampi.sqlite3. This repository is based roughly on the git (http://git-scm.com/) repository structure, except less efficient and jammed into a sqlite3 database instead of directly onto the filesystem. The main reason for this is that crampi is intended to be able to run on Windows as well as Unix, and git performs rather badly on Windows, plus git is hard to install on Windows. Crampi has very few prerequisites so it's pretty easy to get running on your Windows system. Inside crampi.sqlite3, we store a the complete history (including contents) of all the contact entries we've ever imported from any of the address books being synced. Once upon a time, that would have been a horribly inefficient thing to do; think of the many kilobytes of wasted space! But nowadays nobody cares, because you'd have to store an awful lot of contact items to equal the size of a single mpeg-encoded movie, and even a movie takes a tiny fraction of your disk space. On one corporate network I've seen, we imported an Exchange Global Contacts folder with 3708 entries; it takes 4.7 megs, which is 0.0032% of my low-end desktop PC's hard disk. Big deal. Anyway, inside the crampi repository is a set of "branches." Each branch corresponds to the history of a particular backend, such as a MAPI folder or an installed copy of Fat Free CRM. You can import into a branch as often as you want, using the 'crampi ffcrm' or 'crampi mapi' commands. After importing all your branches, you can also merge the changes from one branch to another. Crampi uses the repository to track which branches have been merged into which other branches and what times, and it only merges the particular attributes that of changesd in contacts that have changed from one merge to the next. For example, if you have a contact named Avery Pennarun, and one person changes his email address using Fat Free CRM, and another person changes his phone number in Outlook, crampi will notice those two exact changes next time you do a merge. It'll then merge the two changes into a single entry, and update both databases with the merged data. Neat, huh? Let's not go into too much detail about the merge algorithm, because it's complicated and confusing and not that important to understand in detail right now. But you do have to remember one thing: DON'T LOSE YOUR REPOSITORY DATABASE AFTER MERGING! Crampi's repository is a little bit like git, but it's very *unlike* git in one respect: not every backend it talks to is a complete repository. With git, if one guy loses his repository, it's no big deal, because you can just copy any other guy's repository and get the same stuff. With crampi, only the central repository has all the history. Other databases just track the latest version of each contact, and they don't know anything about merges, so if you lose your central crampi repository, future merges will make a mess. (Mostly they'll just cause duplicate database entries.) If you do lose the crampi repository, you're not totally doomed; you'll probably just have to clean up some duplicate items later. You can use the 'crampi dedupe' command to help with this. Another thing you should know is that crampi can sync between more than two repositories. You can sync two instances of Fat Free CRM (the contact information only, not the notes and opportunities and so on). Or you can sync between two MAPI folders, like if you want to have a personal contacts folder that's synced with the Global Contacts folder (eg. if you're using a Blackberry and it annoyingly refuses to sync your Global Contacts folder for some reason). Because of the way crampi works, you can add synced folders at any time. Installation Details - Windows ------------------------------ For the quickstart steps above to actually work on Windows, you'll need to first install a copy of python, pywin32 (python and pywin32 are two different things), and crampi. The exact versions we used in testing are: - python-2.6.4.msi - pywin32-214.win32-py2.6.exe (pywin32-214.zip) - whatever version of crampi this README comes from Make sure you've also installed Microsoft Outlook and configured it with a default profile. It's very important that the default profile doesn't require you to enter a password, because crampi won't pop up a password prompt! Syncing between Unix and Windows -------------------------------- It's possible to sync between Windows and Unix. In fact, that's most of the point! If you have fat_free_crm, that's probably running on Unix, and if you have MAPI (Exchange/Outlook), that's probably running on Windows. To make it work, all you have to do is mount a shared folder containing the crampi.sqlite3 file, then point crampi at it using the --gitdb option. If you don't look forward to setting up a Windows workstation just to sync Exchange with your Unix system - and who wants extra Windows systems? Ew! - then you're in luck. Crossover Office 9.1.0 (http://www.codeweavers.com/) works correctly with Microsoft Outlook 2003, Python 2.6, pywin32, crampi, and Microsoft Exchange Server. Earlier versions of Crossover (I'm not sure exactly which ones) have known crashiness issues when used with crampi, even though they might work with Outlook by itself. So make sure you have at least 9.1.0. You might also find that other versions of Office work, but I haven't tested them, so good luck. You're better off to use exactly Outlook 2003. It's also possible that the free versions of Wine (1.2.0 or above) might work, assuming you can get Outlook 2003 installed and working. I don't know; I've tried plain Wine many times over the years and just got frustrated, and Crossover relieved my frustration (mostly) for a lousy $40, which was well worth it. If you're not sure, you can download their free demo and make sure it works for you before forking over the cash. After installing Outlook (and setting up a default Outlook profile), python, and pywin32, you can then run crampi in your Crossover Office session like this: $ cxoffice --bottle 'Microsoft Outlook 2003' --cx-app python \ ./crampi mapi-ls Basically, wherever you might have typed > c:\python26\python crampi ... at the DOS prompt, now you type $ cxoffice --bottle 'Microsoft Outlook 2003' --cx-app python \ ./crampi ... at the Unix prompt, and it should work. The really nice thing about running cxoffice under Crossover is that you can now write a single Unix shell script that syncs between fat_free_crm and MAPI. And you can set up that script to run from cron instead of messing with the insane Windows Task Scheduler crap. Just call the Unix version of crampi for fat_free_crm, and the Windows version for MAPI. They both write to the same database, so refs/log/diff/dump/dedupe/etc all work with either version. Questions? Comments? Patches? ------------------------------- This is an early release of crampi and surely has lots of scary bugs. Also, this documentation is probably horribly incomplete. Please send your questions/comments to the mailing list shown at the top of this README. (You don't have to be a subscriber to send messages to the list.) If you make patches to crampi for new features or bugfixes, you can either mail them to the list with git format-patch/send-email, or else fork the crampi project on github.com and send a message to the list telling us what you've added. Enjoy! Have fun, Avery
