== The relax_trunk ==
−
md C:\WinPython27\relax

Go to https://github.com/nmr-relax/relax_trunk <br>
−
cd C:\WinPython27\relax

Click '''Fork'''.
  
−
To clone from a revision number, use '''-r NR'''. This will tell which revision to start taking history from. If you want to include all of the history, just leave that option off, but it will take a very long time, and you really don't need all of it.
+
Now add this as a private remote, by setting the remote name '''hub'''.
−
The older a revision you choose, the longer it will take to import. But you will not be able to "git blame" past the earliest revision you import.

Caution  The information in this section is out of date but is kept for historical reasons. The relax source code is now hosted in a git rather than svn repository.

relax branches at github

You should install msysgit on windows, to do the commands.

The relax_trunk

Go to https://github.com/nmr-relax/relax_trunk
Click Fork.

Now add this as a private remote, by setting the remote name hub. 

 # Windows
 set relax_trunk="C:\WinPython27\relax\relax_trunk"
 set GIT_USER_NAME="GIT_USER_NAME"
 md %relax_trunk%
 cd %relax_trunk%
 # Linux
 bash ;
 relax_trunk=$HOME/relax/relax_trunk
 GIT_USER_NAME="GIT_USER_NAME"
 mkdir -p ${relax_trunk}
 cd $relax_trunk

 git init 
 # Windows
 git remote add origin https://%GIT_USER_NAME%@github.com/nmr-relax/relax_trunk.git
 git remote add hub https://%GIT_USER_NAME%@github.com/%GIT_USER_NAME%/relax_trunk.git
 # Linux
 git remote add origin https://${GIT_USER_NAME}@github.com/nmr-relax/relax_trunk.git
 git remote add hub https://${GIT_USER_NAME}@github.com/${GIT_USER_NAME}/relax_trunk.git 

 # Or if you have setup a SSH key in github, and tested with: ssh -T git@github.com
 git remote set-url origin git@github.com:nmr-relax/relax_trunk.git
 git remote set-url hub git@github.com:${GIT_USER_NAME}/relax_trunk.git

 git fetch origin
 git checkout --track origin/master
 git fetch hub

 #Build
 scons

 ## Now we add the user scripts repo
 # Windows
 git clone https://%GIT_USER_NAME%@github.com/nmr-relax/relax_scripts.git
 # Linux
 git clone https://${GIT_USER_NAME}@github.com/nmr-relax/relax_scripts.git

Go to https://github.com/nmr-relax/relax_scripts
Click Fork. 

 cd relax_scripts
 # Windows
 git remote add hub https://%GIT_USER_NAME%@github.com/%GIT_USER_NAME%/relax_scripts.git
 # Linux
 git remote add hub https://${GIT_USER_NAME}@github.com/${GIT_USER_NAME}/relax_scripts.git

The relax_disp

Go to https://github.com/nmr-relax/relax_disp
Click Fork.

Now add this as a private remote, by setting the remote name hub. 

 # Windows
 set relax_disp="C:\WinPython27\relax\relax_disp"
 set GIT_USER_NAME="GIT_USER_NAME"
 md %relax_disp%
 cd %relax_disp%
 # Linux
 bash ;
 relax_disp=$HOME/relax/relax_disp
 GIT_USER_NAME="GIT_USER_NAME"
 mkdir -p ${relax_disp}
 cd $relax_disp

 git init 
 # Windows
 git remote add origin https://%GIT_USER_NAME%@github.com/nmr-relax/relax_disp.git
 git remote add hub https://%GIT_USER_NAME%@github.com/%GIT_USER_NAME%/relax_disp.git
 # Linux
 git remote add origin https://${GIT_USER_NAME}@github.com/nmr-relax/relax_disp.git
 git remote add hub https://${GIT_USER_NAME}@github.com/${GIT_USER_NAME}/relax_disp.git 

 git fetch origin
 git checkout --track origin/master
 git fetch hub

 #Build
 scons

 ## Now we add the user scripts repo
 # Windows
 git clone https://%GIT_USER_NAME%@github.com/nmr-relax/relax_scripts.git
 # Linux
 git clone https://${GIT_USER_NAME}@github.com/nmr-relax/relax_scripts.git

Go to https://github.com/nmr-relax/relax_scripts
Click Fork. 

 cd relax_scripts
 # Windows
 git remote add hub https://%GIT_USER_NAME%@github.com/%GIT_USER_NAME%/relax_scripts.git
 # Linux
 git remote add hub https://${GIT_USER_NAME}@github.com/${GIT_USER_NAME}/relax_scripts.git

How the import to github was done

Based on these posts and on this recommended post, and also this post.

You need an authors.txt file, to correctly convert the metadata. 

 bash ;
 relax=$HOME/backup/relax ;
 relax_trunk=${relax}/relax_trunk ;
 relax_disp=${relax}/relax_disp ;
 GIT_USER_NAME="GIT_USER_NAME" 
 mkdir -p ${relax_trunk} ${relax_disp} ;

 git svn clone http://svn.gna.org/svn/relax/trunk --no-metadata -A authors.txt ${relax_trunk} ;
 cp authors.txt ${relax_trunk} ;
 cat ${relax_trunk}/.git/config
 cp ${relax_trunk}/.git/config ${relax_trunk}/.git/config_bck
 awk '{gsub(a,b);print}' a=".*authorsfile =.*" b="        authorsfile = ${relax_trunk}/authors.txt" ${relax_trunk}/.git/config_bck > ${relax_trunk}/.git/config
 cat ${relax_trunk}/.git/config

 git svn clone http://svn.gna.org/svn/relax/branches/relax_disp --no-metadata -A authors.txt ${relax_disp} ;
 cp authors.txt ${relax_disp} ;
 cat ${relax_disp}/.git/config
 cp ${relax_disp}/.git/config ${relax_disp}/.git/config_bck
 awk '{gsub(a,b);print}' a=".*authorsfile =.*" b="        authorsfile = ${relax_disp}/authors.txt" ${relax_disp}/.git/config_bck > ${relax_disp}/.git/config
 cat ${relax_disp}/.git/config

Setup remotes to github

For branch trunk

 cd $relax_trunk
 git config --add user.name "Your Name"
 git config --add user.email you@example.com
 git config --add core.editor "nano"
 git config --add github.user ${GIT_USER_NAME}
 # If you are a member of the organization, with writing permissions, then do:
 git remote add origin https://${GIT_USER_NAME}@github.com/nmr-relax/relax_trunk.git

Now go to github.com at https://github.com/organizations/nmr-relax click Repositories -> New.
Call it relax_trunk. We want to preserve history , so do not Initialize this repository with a README or anything like, README or .gitignore.

Then send svn branch master of to github 

 git push -u origin master

For branch relax_disp

 cd $relax_disp
 git config --add user.name "Your Name"
 git config --add user.email you@example.com
 git config --add core.editor "nano"
 git config --add github.user ${GIT_USER_NAME}
 # If you are a member of the organization, with writing permissions, then do:
 git remote add origin https://${GIT_USER_NAME}@github.com/nmr-relax/relax_disp.git

Now go to github.com at https://github.com/organizations/nmr-relax click Repositories -> New.
Call it relax_disp. We want to preserve history , so do not Initialize this repository with a README or anything like, README or .gitignore.

Then send svn branch master of to github 

 git push -u origin master

git operations

Get new changes from svn repository and push to github 

git co master
git svn fetch
git rebase --onto remotes/git-svn
git push origin master

Saving credentials

See this post 

echo "machine github.com login ${GIT_USER_NAME} password SECRET" >> ~/.netrc
chmod 0600 ~/.netrc
ls -la ~/.netrc
cat ~/.netrc

Setup cronjob

Checking each 15 minutes 

crontab -e

# Add
*/15 * * * * $HOME/backup/nmrrelax_sync_svn_git.sh

Sync script from SVN to Github

#!/bin/bash
# -*- coding: UTF-8 -*-

# exec test
