This is the beta LArSoft redmine project and the future home of the LArSoft redmine project.

h1. LArSoftWiki (beta)

*This page is in beta and content is still under construction.*  Will go live when the migration to git/cmake is completed.

The LArSoft software is designed to work for all planned and running liquid argon experiments at Fermilab. It is written in C++ and built on the "ROOT":http://root.cern.ch data analysis software, and the "art":https://cdcvs.fnal.gov/projects/art/wiki analysis framework supported by the Fermilab Scientific Computing Division for intensity frontier experiments.

To join the LArSoft mailing list, please follow these "instructions":http://listserv.fnal.gov/users.asp#subscribe%20to%20list using the list name LARSOFT.

h1. Preliminaries

* *Beta testers:  [[ Special instructions for beta testers | read this first ]]*

* Fermilab computing accounts:  see the instructions on the [[larsoftsvn:Fermilab Computing Access]] page if you need an account.

* See [[larsoftsvn:Load Balanced Access to General Purpose VMs]] for information on accessing experiment VMs at Fermilab (e.g., lbnegpvm0X, uboonegpvm0X, etc., collectively known as GPCF.).

* See the [[LArSoftWiki#documentation|documentation]] section for information on working with/developing LArSoft code, and using git, git flow, mrb and other tools you will need.

* The procedures and tools for building and developing software with this system are _completely different_ from those of the previous system based on svn repositories and the SoftRelTools build system. See the [[LArSoftWiki#documentation|documentation]] section for details.

h2. Where to find the software

* [[ The Fermilab core LArSoft installation ]]

* [[ Experiment-specific code and re-factoring ]]

h3. Re-factoring of experiment-specific software

Most experiment-specific code, fcl and gdml files have been removed from the @larcore@, @lardata@, @larevt@ and @larsim@ repositories and moved into beta versions of experiment-specific git repositories. (One exception to this statement is that the @DetId_t@ enum type, which effectively maps detector name strings to integers, remains in core LArSoft, pending migration to a new, string-based mechanism for storing and using this information. Other exceptions include fcl files that were not identified during the initial migration.) The beta versions of experiment-specific repositories are the following:

|*Product 

repository

name* | *repository url (all in Redmine)* | lxr link 

                                            (not yet avail) | Redmine browser |

|lbnecode| ssh://p-lbnecode@cdcvs.fnal.gov/cvs/projects/lbnecode | -- | "redmine":https://cdcvs.fnal.gov/redmine/projects/lbnecode/repository |

|uboonecode| ssh://p-uboonecode@cdcvs.fnal.gov/cvs/projects/lardata | -- | "redmine":https://cdcvs.fnal.gov/redmine/projects/uboonecode/repository |
