# I'm scared to upgrade.
|

Why? Don't ya trust me? I won't break your stylesheets. Cross my heart. All those
|
||
|
|
200+ github issues were feature requests. Honest. But you know, they might change
|
||
|
|
a little. Probably not in any meaningful way. Like a default that used to be
|
||
|
|
specified in the output might be omitted because it's the browser default anyway.
|
||
|
|
|
||
|
|
## Trust but verify.
|
||
|
|
|
||
|
|
But you should probably keep me on my toes. Follow these simple steps to see
|
||
|
|
what changed to your stylesheets:
|
||
|
|
|
||
|
|
*(Steps beginning with a $ are command line commands. Don't type the $.)*
|
||
|
|
|
||
|
|
1. $ cd my_compass_project
|
||
|
|
2. $ compass compile --force
|
||
|
|
3. $ cp -r stylesheets stylesheets.backup
|
||
|
|
4. $ gem install compass --pre # you might need to type sudo first if you're on mac or linux.
|
||
|
|
5. $ compass compile --force
|
||
|
|
6. Take note of any deprecation warnings printed in red during the compile.
|
||
|
|
7. If you have textmate and installed the `mate` command line tool:<br>
|
||
|
|
$ diff -r stylesheets.backup stylesheets | mate
|
||
|
|
8. If you have not installed the `mate` tool:<br>
|
||
|
|
$ sudo ln -s /Applications/TextMate.app/Contents/Resources/mate /usr/local/bin/mate
|
||
|
|
Then perform step 7.
|
||
|
|
9. If you do not have Textmate, run the diff command like so:
|
||
|
|
$ diff -y -r stylesheets.backup stylesheets | less
|
||
|
|
10. Scroll or use your arrow keys to review the differences between the files.
|
||
|
|
11. If you're satisfied: $ git commit -a -m "Upgraded compass"
|
||
|
|
12. If you're scared again:
|
||
|
|
A. Don't panic.
|
||
|
|
B. Read the [CHANGELOG](http://compass-style.org/docs/CHANGELOG/) and
|
||
|
|
see if the changes are explained there.
|
||
|
|
B. Send an email to the [mailing list](http://groups.google.com/group/compass-users)
|
||
|
|
explaining the problem and providing enough context like snippets from your diff
|
||
|
|
and the relevant snippets of your sass/scss files. In rare cases we might request
|
||
|
|
that you construct a simple compass project that exhibits the issue and make an
|
||
|
|
archive of it and send us an email with it attached.
|
||
|
|
C. If it's pretty obviously a bug. Please file an issue
|
||
|
|
on [github](http://github.com/chriseppstein/compass/issues). If you're experiencing
|
||
|
|
a crash, please run the command with the --trace option and record the output for
|
||
|
|
diagnostic purposes.
|
||
|
|
D. $ sudo gem uninstall compass
|
||
|
|
Select the newest version of compass. You have now downgraded to the old
|
||
|
|
version of compass.
|
||
|
|
E. $ compass compile --force
|
||
|
|
F. Diff the folders as in steps 7 through 9.
|
||
|
|
13. Breathe a sigh of relief.
