Here we assumed that you are working locally with the default development organisation of the NEMO reference (trunk + branches + releases in your working directory),
if not browse to Developers homepage


Create a branch

For development branches, we tend to add one level of subdirectory corresponding to the current year, and an additional item in the name corresponding to the workplan. For branch naming conventions, see Developers/Developing Code Changes.

svn copy trunk branches/'Current_year'/'Name_of_the_new_branch'

Mirror a different branch (hazardous)

Your working copy was based on your initial dev. branch and you want to update to a different branch, conflicts are unavoidable and will be pretty complicated to resolve.

svn sw 'URL[@PEGREV] [WCPATH]'

Manage versioned items

Add a new NEMO routine

Use the template from NEMO/trunk/src/OCE/module_example

svn copy trunk/src/OCE/module_example branches/'Current_year'/'dev_branch'/'PATH/routine.{f90,F90,h90}'

Add a new item / Remove a item

svn {add,del} 'WCPATH'

Info / Status / Log

Display information about a local or remote item

svn info 'WCPATH[@PEGREV]'

Display the current state of the working copy wrt the one mirrored in the repository

svn status [-[qu]] '[WCPATH]'

Display all commits performed to your working repository since its creation

svn log --verbose --stop-on-copy 'WCPATH'

Revert local changes

svn revert [--depth {empty,files,immediates,infinity}] 'WCPATH'

Manage versioned properties on items

svn:keywords for commit infos on routines

If the svn:keywords property is not defined on a NEMO routine, set it in order to get the functionality of $Id keyword replacement in all committed files with the commit informations (URL, author, date and revision)

svn pset svn:keywords Id 'WCPATH'

svn:mime-type for syntax highlighting and merging process

Most of versioned files
If you want to apply a specific

svn:executable for executable permissions of shell scripts

svn {pset,pdel} svn:executable 'WCPATH'

svn:externals for defining external sources

Merging sources

Apply the differences between two sources to a working copy path


Commit changes to the repository

svn co [-m 'log message in one line'] items

Recommended syntax to be added in the commit message

  • If the commit is related to one or several tickets, we highly suggest to add the commit message as ticket comment.
    To do so, you can use one of the word in the list addresses re references refs see followed by usual ticket link(s).
    Ex: see #1948 somewhere in the commit message to link with #1948
  • If the commit is a fix for one or several tickets, you can close them with the commit.
    To do so, you can use one of the word in the list close closed closes fix fixed fixes followed by usual ticket link(s).
    Ex: fix #1948 somewhere in the commit message to close #1948 without a browser.

Be careful if you mix the 2.

Then in the appropriate directory

# Commit and write the log message (ticket link #.... and so on) in your editor
svn ci files_list
# `svn ci` without files list will commit all modified files recursively from the current directory
# or directly from the command line of the shell session
svn ci -m 'log_message' files_list
# Tip: set your editor for SVN for multi-lines commit message
# for sh  and other related shells, interesting to include it in ~/.profile or ~/.bash_profile)
export SVN_EDITOR='your_favourite_editor' 
# for csh  "    "      "      ""  ,      "      ""    "    "" "" ~/.login                     )
setenv SVN_EDITOR='your_favourite_editor'

Push modified external items from a working copy

Use explicit option with SVN commit command, think that no revision has to be set on related ext def (equivalent to @HEAD)

svn ci --include-externals ... 

With the new layout of the repository, some may encounter downloading or updating issues with

svn co -r REV URL

Use instead the more robust syntax

svn co URL@PEG (REV ~ PEG)
