pdfcroptexlive
I'm compiling
\documentclass{article}
\begin{document}
\immediate\write18{pdfcrop PT1-matlab.pdf}
\end{document}
with
lualatex.exe -synctex=1 -interaction=nonstopmode --shell-escape %.tex
on Windows but it fails silently and no PT1-matlab-crop.pdf is created.
pdfcrop PT1-matlab.pdf (./document.aux))
Here is how much of LuaTeX's memory you used:
It used to work with TeX Live 2015 and running
pdfcrop PT1-matlab.pdf
in the TeX Live command line results in a croppped PDF.
The problem line appears to be in content/main.js, line 144 (line number accurate as of 2011/07/22, may be different in the future). Try the following steps:
Find the LaTeX-It xpi file. It's actually a renamed .zip file, so you'll need to uncompress it to edit its files. 7-Zip will extract the file without renaming, but worst case, you can rename the .xpi file to a .zip extension and then uncompress it into its own folder.
In the file content/main.js, replace lines 144-147 with
var temp_dir="c:\\temp"; temp_file = init_file(temp_dir);
where the first statement refers to any writable temporary folder with a simple path. Make sure to double any backslashes in the path, since Javascript uses the backslash character to escape things like newlines, tabs, etc.
Recompress the extracted folder into a .zip, then rename it to have a .xpi extension. Replace the old .xpi file with your updated one.
At the author's GitHub site, post a bug report asking for better support of tildes in paths, or a feature request asking for the ability to override the default temporary folder with one of your choosing.
Perhaps there is a problem with redirection of standard/error output with your Perl version. Try updating. The current version is 5.16.1.1601.
Also I have written a test script that tries different execution methods with and without redirecting:
#!/usr/bin/env perl
use strict;
$^W=1;
use File::Spec::Functions qw(devnull);
my $null = devnull();
my $prg = '"C:\Program Files\gs\gs9.06\bin\gswin64c.exe"';
# $prg = '"C:\Program Files\gs\gs9.05\bin\gswin32c.exe"';
my $testfile = 'Instructions-autopp.pdf';
# $testfile = 'test.pdf';
my $cmdline =
"$prg -sDEVICE=bbox -dBATCH -dNOPAUSE -c save pop -f $testfile";
sub analyze {
if ($? == -1) { print "! Execution error: $!/$^E\n"; }
elsif ($? & 127) { print sprintf "! Signal: %d\n", $? & 127; }
elsif ($? != 0) { print sprintf "! Exit code: %d\n", $? >> 8; }
else { print "* No error.\n"; }
}
sub test {
print "\n*** system() ***\n";
system($cmdline);
analyze();
print "\n*** backticks ***\n";
my $result = `$cmdline`;
analyze();
print "==========\n";
print $result;
print "==========\n";
print "\n*** pipe ***\n";
my $ret = open(IN, "$cmdline |");
if ($ret) {
while (<IN>) {
chomp;
print "[[$_]]\n";
}
close(IN);
analyze();
}
else {
print "! Error: Execution error: $!/$^E\n";
}
}
test();
print "\n*** with stderror redirection ***\n";
$cmdline .= " 2>&1";
test();
print "\n*** with stderror and stdout redirection ***\n";
$cmdline .= " 1>$null";
test();
1;
__END__
The result (example with win32/ActivePerl 16.0.1):

In the new luatex \write18 is no longer special. To get the functionality back: Load the package
shellescand read its documentation.
