thank you for your help , just I want to say I am not blindly running your code I created a backup before doing anything Smilie

But my code expects .pm files, not .m files! You can't run it on .m files and expect it to work. It can't edit 'in place' -- very few noninteractive things besides 'ed' do -- and making something which did would be far more difficult.

Yes agree, but like you I have a lot of file *.m I don't want to rename to *.pm all files if, I did back for all project I would like simply to run it in *.m files .
what I should change to do this .?

All right, this should generate .pm files from .m files instead of vice versa:

Code:
$ cat ocstr2.awk

# If the code contains @"LBL_....", replace it with C_LBL_... and
# remember the labels for later.
match($0, /@"LBL_[0-9]*\"/) {
        S=$0; P=""

        do        # Loop until there's nothing left in the right half
        {
                A[L=substr(S, RSTART+2, RLENGTH-3)]++; # Remember label
                P=P substr(S, 1, RSTART-1) "C_" L;
                S=substr(S, RSTART+RLENGTH);
        }
        while(match(S, /@"LBL_[0-9]*\"/)); # Keep hunting for more labels

        $0=P S; # Update the line to be printed
}

# If we are given file.pm, print into file.m
{       O=FILENAME;
        sub(/[.]m$/, ".pm", O);
        print > O;      }

END {
        for(L in A) printf("NSString *const C_%s = @\"%s\";\n", L, L);
}

too many open files
HI I am trying to run the following script for 317 files (*.m) and I get this error :
awk: xfile.m makes too many open files
what's the solution pls ?

Code:
$ cat ocstr2.awk

# If the code contains @"LBL_....", replace it with C_LBL_... and
# remember the labels for later.
match($0, /@"LBL_[0-9]*\"/) {
        S=$0; P=""

        do        # Loop until there's nothing left in the right half
        {
                A[L=substr(S, RSTART+2, RLENGTH-3)]++; # Remember label
                P=P substr(S, 1, RSTART-1) "C_" L;
                S=substr(S, RSTART+RLENGTH);
        }
        while(match(S, /@"LBL_[0-9]*\"/)); # Keep hunting for more labels

        $0=P S; # Update the line to be printed
}

# If we are given file.pm, print into file.m
{       O=FILENAME;
        sub(/[.]m$/, ".pm", O);
        print > O;      }

END {
        for(L in A) printf("NSString *const C_%s = @\"%s\";\n", L, L);
}

It would have helped to know some basics, as my crystal ball of precognition is in repair right now: OS, version, user credentials, ....

You might want to have a look at ulimit with the user under which you want to run the script - maybe the account isn't allowed to open so many files. You will have to correct this with the root user.

Could you please explain what the script does/should do? Maybe it is possible to straighten the algorithm a bit.

I hope this helps.

the script create file list and search into all files *.m in specific directory for a reg-exp
Code:
Code:
@"LBL_[[0-9]]+"

exp: @"LBL_75847" , and write those matchs to constant.h if there are not written (no duplication into the file constants) like this

Code:
Code:
NSString *const C_LBL_[[0-9]] = thematch; // exp NSString *const C_LBL_78784 = @"LBL_78784";

Code:
Code:
NSString *const C_LBL_[[0-9]] = thematch; // exp NSString *const C_LBL_78787 = @"LBL_78787";

moreover this script should also replace all matched
Code:
Code:
@"LBL_[[0-9]]+"

into *.m files with the constant var which is
Code:
Code:
 C_LBL_[[0-9]]+

REF

Thanks in advance

$ ulimit -Sn
