How to select and read #define lines from a code file

Question

Hi,
I would like to read a .m file
and select the lines which begins with '#define PL-KEY', like
{quote}
#define PL-KEYTAG TAG_values
#define PL-KEYGROUP GROUP_value
#define PL-KEYINFO "INFO_ValueTxtMax120Char" // could be max 120 char
..... more PL-KEY keys
{quote}
and put the rest of that line until a '//' or '/*' , like
{quote}
TAG TAG_values
GROUP GROUP_value
INFO "INFO_ValueTxtMax120Char"
{quote}
into something like a list where my code above will loop through.
I thought using something like
cat "path/to/code.h" | while read line
do
#... what do I have to with "$line" ...
if [[ "$line" == #define PL-KEY* ]] ; then
# yes then... then what????
done
any suggestions?? I noticed today, I am still no shell expert
Thanks again

I can't help much with PlistBuddy, as I just recently found out about it myself.
But for the code, here are some adjustments based on your comments.
I stuck with shell scripting because you seem to be more comfortable with shell scripting, vs awk or perl.
#!/usr/bin/env bash
while read lb_def rest
do
if [[ "$lb_def" = #define && "$rest" = PL_KEY* ]]; then
rest=${rest#PL_KEY}
echo "${rest%/[/]}"
fi
if [[ "$lb_def" = # && "$rest" = define PL_KEY* ]]; then
rest=${rest#define }
rest=${rest#PL_KEY}
echo "${rest%/[/]}"
fi
done </path/to/code.h
If PL_KEY has stuff in front if it, like one of your posts where it was kPL_KEY, then you could modify the uses of PL_KEY to include the 'k', or you could wildcard it. If a single character, then
if [[ "$lb_def" = #define && "$rest" = ?PL_KEY* ]]; then
rest=${rest#?PL_KEY}
If multiple characters could prefix PL_KEY, then you can use the multi-character wildcard
if [[ "$lb_def" = #define && "$rest" = PL_KEY ]]; then
rest=${rest#*PL_KEY}
If you are worried, that PL_KEY might exist in the comment, then you could strip the comment before doing the tests
#!/usr/bin/env bash
while read lb_def rest
do
rest=${rest%/[/]} # remove comments.
if [[ "$lb_def" = #define && "$rest" = PL_KEY ]]; then
rest=${rest#*PL_KEY}
echo "${rest}"
fi
if [[ "$lb_def" = # && "$rest" = define PL_KEY ]]; then
rest=${rest#define }
rest=${rest#*PL_KEY}
echo "${rest}"
fi
done </path/to/code.h
Is that better?
