regcmp(1)                                               regcmp(1)



NAME
     regcmp - compiles regular expressions with a file

SYNOPSIS
     regcmp [-] file...

ARGUMENTS
     -    Places the output in a file suffixed .c.

     file Specifies the file to be compiled.

DESCRIPTION
     regcmp, in most cases, precludes the need for calling regcmp
     from C programs.  This saves on both execution time and
     program size.  The command regcmp compiles the regular
     expressions in file and places the output in file.i.

     The format of entries in file is a name (C variable)
     followed by one or more blanks followed by a regular
     expression enclosed in double quotes.  The output of regcmp
     is C source code.  Compiled regular expressions are
     represented as extern char vectors.  file.i files may thus
     be included into C programs, or file.c files may be compiled
     and later loaded.

     In the C program which uses the regcmp output,
     regex(abc,line) will apply the regular expression named abc
     to line.  The status messages for this command are self-
     explanatory.

EXAMPLES
     This C program:

        name``([A-Za-z][A-Za-z0-9_]*)$0''

        telno
        ``,1}([2-9][01][1-9])$0){0,1} *''
        ``([2-9][0-9]{2})$1[ -]{0,1}''
        ``([0-9]{4})$2''

     that uses the regcmp output

        regex(telno, line, area, exch, rest)

     will apply the regular expression named telno to line.
