Automated way to check for PGF version

This is one way to check for the version of PGF that is installed in an automated way. First create a tex file with the following contents:


Say you named it test-pgf-version.tex. Then:

pdflatex test-pgf-version.tex
cat test-pgf-verson.log | grep PGFVersion | sed ‘s/PGFVersion=//’

should display the version number. I happen to need to do this from R so using similar logic:

logFile <- ‘testpgfversion.log‘    
logContents <- readLines( logFile )
match <- logContents[ grep(‘PGFVersion=‘, logContents) ]
version <- gsub([=AZaz]‘,”,match)

which accomplishes the same task as the second line above.

    1. As far as I understand, \makeatletter makes the @ symbol useable in commands, this is necessary to use the \@@end command which unceremoniously stops all compilation and exits tex.
