Here is a small patch (attached) that adds wildcard matching for the V
command. Also it fixes what i feel is a bug with V in that it also reports
all functions in the scope.
I'm not a seasoned bash scripter so there are probably some things that can
be fixed. But for now it seems to be quite robust.
A few intersting points to consider.
I chose to call declare -p <var> for each var to be able to weed out any
false positives the previous functions could have let through. For example
the function:
strange() {
echo "This is an
}
odd=but still legal
construct"
}
could fool the code unless declare -p was called on the name odd. declare -p
will only put a closing bracket at the far right if it's part of a string.
And thus the function detection will work well for all cases except those but
they should be quite rare and if they occur the declare -p disqualifies them.
You could get a variable output several times in extreme cases. But i'm not
sure those few cases warrant adding some code to ensure each variable is
printed only once since it will slow down the variable listing additionally.
