Re: Installation Check script

15 Oct 2015

      I would change the script so it exits with code 0 unless a failure occurs (an inverse of your current logic).

Coding in my phone, but I would do something like...

#!/usr/bin/env bash
kpsewhichFound=0
possibleLocations=(
	'/usr/texbin'
	'/Library/TeX/texbin'
)
for eachLocation in "${possibleLocation[@]}"; do
	if [[ -e "${eachLocation}/kpsewhich" ]]; then
		(( kpsewhichFound++ ))
		echo "Found kpsewhich at $eachLocation"
		texBinLocation="$eachLocation"
	fi
done
if [[ "$kpsewhichFound" = 0 ]]; then
	echo "Failed"
	exit 1
else
	echo "Passed"
	foo
fi
exit 0

I'm not familiar with TeX, so replace the foo line with whatever you actually need kpsewhich for.

Also, echo is great (and I use it above for sake of simplicity), but I would suggest possibly redirecting to a log file, or using the command "logger" instead.  Either of which makes it easier to see what's going on in this kind of examination.

I'm attempting to update an installer for a TeX package that I help develop to account for SIP on El Capitan (in case it's relevant, the installer is built with Packages because I haven't yet figured out how to use the command-line tools that come with XCode).  The installer has a Installation Check script which makes sure that the computer has a TeX installation and a post-install script which copies some of the installed files into the TEXMF tree and runs texhash so that TeX is aware of the new files.
On Yosemite and earlier, I could rely on the the tools I needed (to locate the TEXMF tree and run texhas) being on the /usr/texbin/ path, but on El Capitan, they're on /Library/TeX/texbin/ (since /usr is unavailable due to SIP).  However, when I attempt to update my scripts to look in that location (in addition to the old location, in order to maintain backwards compatibility), the Installation Check is failing when run by the installer in El Capitan (it still works on Yosemite). When run from the command-line, the check passes (on both versions of OSX).  While I haven't built an installer which would bypass the Installation Check, presumably the post-install script will fail too since it requires the same tool that the Installation Check is looking for (and not finding).
Does anyone have any idea why this might happening and what I can do to fix it?
This is the Installation Check script I'm attempting to use:
...
#!/bin/bash
# Test to see if we have a valid TeX installation
TEXMFLOCAL=`kpsewhich -var-value TEXMFLOCAL`
if [ -n "$TEXMFLOCAL" ]; then
   echo "Passed 1"
   exit 0
fi
TEXMFLOCAL=`/usr/texbin/kpsewhich -var-value TEXMFLOCAL`
if [ -n "$TEXMFLOCAL" ]; then
   echo "Passed 2"
   exit 0
fi
TEMFLOCAL=`/Library/TeX/texbin/kpsewhich -var-value TEXMFLOCAL`
if [ -n "$TEXMFLOCAL" ]; then
   echo "Passed 3"
   exit 0
fi
echo "Failed"
exit 1
These are the contents generated for the install.log when running the installer built with this script in El Capitan (a failed installation):
