Environment & setup

git clone https://github.com/cmstas/NanoTools
cd NanoTools/
source /cvmfs/cms.cern.ch/cmsset_default.sh
cd /cvmfs/cms.cern.ch/slc7_amd64_gcc700/cms/cmssw/CMSSW_10_2_13/ ; cmsenv ; cd -
cd NanoCORE
make test -j12
cd ..

Unit tests

Unit tests of NanoCORE/ are inside NanoCORE/Tools/unit_tests/ and can be run with make test inside of NanoCORE/.

Skimmer

One must long on to slc7 machines (e.g. uaf-1/7/8/10 for this.
The newer linux version won't work. (e.g. uaf-2/3)
For future we will have to one day fix this as slc7 will be gone.

ssh uaf-10.t2.ucsd.edu
mkdir -p workarea/skimtest
cd workarea/skimtest

Style

We use clang-format based on LLVM style to format our code. To format the ElectronSelections.cc file in-place, do

clang-format -style="{BasedOnStyle: llvm, IndentWidth: 4, ColumnLimit: 120, AllowShortIfStatementsOnASingleLine: true, AllowShortBlocksOnASingleLine: true}" -i ElectronSelections.cc

Add this to the ~/.vimrc and use vim to code. (Assumes you are working on UAF)

autocmd BufNewFile,BufRead *.cc,*.h,*.C,*.cxx set formatprg=clang-format\ -style=\"{BasedOnStyle:\ llvm,\ IndentWidth:\ 4,\ ColumnLimit:\ 100,\ AllowShortIfStatementsOnASingleLine:\ true,\ AllowShortBlocksOnASingleLine:\ false,\ BreakBeforeBraces:\ Allman}\"

To format your code, press ggvGgq.

Grid certificate installation

Copy the certificate to a file named myCert.p12 to the computer where you will run voms-proxy-init.

Extract your certificate (which contains the public key) and the private key:

Extract the certificate: openssl pkcs12 -in myCert.p12 -clcerts -nokeys -out $HOME/.globus/usercert.pem Extract the encrypted private key: openssl pkcs12 -in myCert.p12 -nocerts -out $HOME/.globus/userkey.pem You must set the mode on your userkey.pem file to read/write only by the owner, otherwise voms-proxy-init will not use it: chmod 600 $HOME/.globus/userkey.pem chmod 600 $HOME/.globus/usercert.pem Delete the myCert.p12 file created above to avoid security issues.
