Hi
I need to detect the actual programming language of a script.
A way of detecting it is to examine the first line searching for the
"sha-bang" (#!), e.g.,
#!/bin/bash
or
#!/usr/bin/perl
However, there are cases where this is not enough, since the script,
although it has #!/bin/sh is actually written (and interpreted) in
another language, e.g., Tcl.
So my question is, is there another way of detecting the actual
language? I mean, another convention?
Is this internal to the script, or external (looking in)?
I need to detect the language of the script in order to highlight it
accordingly (GNU source-highlight http://www.gnu.org/software/src-highlite)
for instance I have some tcl scripts that start as follows:
#!/bin/sh
# Tcl ignores the next line -*- tcl -*- \
exec wish "$0" -- "$@"
and I want them to be colorized as a Tcl script instead of a shell script
I don't think that you can accurately do what you want, because a
script can call multiple interpreters.
#!/bin/bash
echo 'A shellism'
python <<EOF1
print 'This is a python scriptlet'
print 'It can do many things'
EOF1
echo 'another shellism'
perl <<EOF2
{
print "This is a Perl scriptlet\n";
print "It also can do many things\n";
}
EOF2
echo 'a third shellism'
well that's not a big problem for what I'd like to do :-)
thanks in advance
Lorenzo
