EVe_HallC

EVe_HallC is an event display program for the Hall C HMS and SHMS detector stacks.

Branches

There are several branches currenlty in the JeffersonLab/EVe_HallC repository:

• master: holds code common to both HMS and SHMS stacks
• HMS: holds HMS specific code
• SHMS: holds SHMS specific code
• develop: deprecated
• BetheHeitler: ??

Usage

• Select appropriate branch (HMS or SHMS):
  • git checkout <branch>
• Check for updates:
  • git fetch upstream
  • git merge upstream/<branch>
• Setup environment:
  • setup ROOT 5.34
  • setenv ANALYZER <path/to/podd>
• Build library:
  • make
• Load library into ROOT and start viewer:
  • root -l simEVe.C

Contributions

Contributions/changes to the EVe_HallC repo will follow the same development model as for the Hall C analyzer (hcana) outlined in this link.

They boil down to this:

• Fork repo to your GitHub.
• Do not edit files in the master, HMS or SHMS branches!
• Select appropriate branch for contribution
  • master for changes that affect both HMS and SHMS,
  • HMS or SHMS for spectrometer specific changes,
  • git checkout <branch>
• Check for upstream updates:
  • git fetch upstream
  • git merge upstream/<branch>
• Branch a new <featureBranch> off of selected branch and work on your changes.
  • Make frequent atomic commits with useful commit logs.
  • Test your code.
• When your feature is done:
  • push <featureBranch> to your GitHub repository:
    • git push --set-upstream origin <featureBranch>
  • make pull request to JeffersonLab/<branch> from <you>/<featureBranch> on GitHub.
  • Make sure changes are still compatible with any recent upstream changes and fix if not.

And most of all, good luck. You will need it.

Formatting/Style

Please follow the style conventions (4-space indent, no tabs, etc):

• 4 space indent
• no hard tabs
• no trailing whitespace
• end file with a newline

Vim

Vim users can install this plugin to make use of the .lvimrc defaults file.

vim Docs/localvimrc.vba
:so %
:q

I'd also add this to your ~/.vimrc:

if !exists("g:localvimrc_persistent")
  let g:localvimrc_persistent=2    " save local vimrc responses
endif

Emacs

A .dir-locals.el defaults file is present for Emacs users.

Documentation

Some documentation may be found in the Docs directory, however it has not kept pace with some of the modifications so YMMV.

Acknowledgments

This code is based off an event display originally written by Miha Mihovilovic in 2008 for the Hall A BigBite Spectrometer. Changes are significant and ongoing. See git log for the history.
