WVZAnalysis

Words for Devs

If you're familiar with basic Julia workflow, check out the documentation directly.

New to Julia:

• Download Julia, we require 1.9 or above (for Pkg extension functionality)
  • if you have access to /cvmfs, you can also access Julia via LCG release:

source /cvmfs/sft.cern.ch/lcg/views/dev4/latest/x86_64-centos7-gcc11-opt/setup.sh

• $ cd <path to this repo folder>

• Launch Julia via julia --project=., this is because you want to use Manifest.toml to keep exact versions of packages including all dependencies.

• For the first time only, you should run ]instantiate to install all the depeendencies.

Folder structre:

• The source code of analysis algorithm and cutflows etc. are inside WVZAnalysis/src

Example

$ pwd
/home/jiling/.julia/dev/WVZAnalysis/ 

$ julia --project=.

then in Julia REPL:

julia> using WVZAnalysis

julia> tasks = prep_tasks("VH");
