The Dreamwidth code uses a [[Mercurial]] repository.  However, it also uses code that uses different repository systems like [[subversion]].

#REDIRECT [[Git How To]]
 
+
== Checking out the code ==
+
 
+
Get the bootstrap script that downloads all of the code:
+
 
+
wget http://hg.dwscoalition.org/dw-free/raw-file/e4be2e864b95/bin/bootstrap.pl
+
 
+
If your <code>$LJHOME</code> environment variable is set up (see [[Dreamwidth Scratch Installation]] for more information on this), run the script:
+
 
+
perl bootstrap.pl
+
 
+
Checking out all the various packages and repositories will take same time.  Afterwards, you can delete the bootstrap script:
+
 
+
rm bootstrap.pl
+
 
+
== Working with $LJHOME/bin/cvsreport.pl ==
+
 
+
The workhorse that ties all the version control systems of all the code bases together is <code>$LJHOME/bin/cvsreport.pl</code>.  With it, you can update to new versions and track changes.
+
 
+
Here is a list of the options that come up with <code>bin/cvsreport.pl -help</code>:
+
 
+
--help          Get this help
+
--sync          Put files where they need to go.
+
                All files, unless you specify which ones.
+
--diff          Show diffs of changed files.
+
--cvsonly      Don't consider files changed in live dirs.
+
--liveonly      Don't consider files changed in the CVS dirs.
+
--init          Copy all files from cvs to main, unconditionally.
+
--update        Updates files in the CVS dirs from the cvs repositories.
+
--justfiles -1  Only output files, not the old -> new arrow. (good for xargs)
+
--livelist -ll  Output the list of all accounted-for files.
+
--which        Output the source of the given file
+
--these -t      Refuse to --sync if no files are specified.
+
--map          Like --livelist and --which combined.
+
--all          Overrides --these, allowing --sync to run with no args.
+
--print-current-branches -pcb    Print repositories and their current branches
+
--print-branches -pb    Print repositories and their branches.
+
--print-repos -pr        Print repositories and their resource URLs.
+
--print-vars -pv        Print configuration variables specified in .conf files.
+
--no-space-changes -b    Do not display whitespace differences.
+
 
+
=== Updating to the latest code ===
+
 
+
See the [[Dev Maintenance]] article for instructions on this.
+
 
+
=== Displaying code changes ===
+
 
+
This will show all the changes you've made to the code:
+
 
+
.$LJHOME/bin/cvsreport.pl -diff
+
 
+
You can make a patch by directing this output to a file (see [[Dev Patches]] for more information on patches):
+
 
+
.$LJHOME/bin/cvsreport.pl -diff > PATCHFILE.
+
 
+
=== Reverting changes ===
+
 
+
There is unfortunately no <code>.$LJHOME/bin/cvsreport.pl -revert</code>. One way to revert changes is to delete the file with the changes from the live code and then run:
+
 
+
bin/cvsreport.pl -sync -cvsonly
+
 
+
== Committing changes ==
+
 
+
Right now, only <ljuser>xb95</ljuser> can do this.
+
 
+
# Apply patch to live code
+
# Test the patch
+
# Sync to the cvs copy of the code:
+
# <code>hg diff</code> in the repository
+
# <code>hg commit</code>
+
# <code>hg push</code>
+
