The package gitver requires -shell-escape to fetch git metadata from the manuscript's git repository on the local filesystem.
However, it is needless to pass the shell-escape flag when compiling the source outside of a gitVCS repo (such as on my advisor's machine). It is tedious to comment-out and comment-in this line appropriately. It is also hard to change other collaborator's (good) habits of not compiling with -shell-escape enabled. However, gitver complains loudly and errors out/halts if shell-escape is not detected.
Hence, can I change my preamble in such a way that a generic source line (not just to loading gitver package, but the same argument applies to minted and other generic latex commands) is executed only when compiled with shell-escape?
Minimal conceptual example:
documentclassarticle
%%% Somehow detect shell-escape here
usepackagegitver % <-- load only if compiled with shell-escape
%%% end of test
begindocument
Hello world!

Imho you should make a feature request for the package. It should have a "warn" mode and quit cleanly if shell-escape is not enabled. As you said: it is a pain if such packages then errors.

You can use pdftexcmds and define a three-branch test:
usepackagepdftexcmds
makeatletter
newcommandShellEscapeURN[3]%
ifcasepdf@shellescape
expandafter@firstofthree % 0 = no shell escape
or
expandafter@secondofthree % 1 = unrestricted
or
expandafter@thirdofthree % 2 = restricted
else
expandafter@firstofthree
fi
#3#1#2%
providecommand@firstofthree[3]#1
providecommand@secondofthree[3]#2
providecommand@thirdofthree[3]#3
makeatother
The three arguments are “code for Unrestricted shell escape”, “code for Restricted shell escape” and “code for No shell escape” respectively.
In your case,
ShellEscapeURNusepackagegitver
It might be more convenient to use expl3 so as not to expose the actual values of the integer variable denoting the status of shell escape.
usepackageexpl3
