Fastest alternatives to flattening a non-uniform nested array with regex?
Hello,
I'm looking at simplfying a function that flattens an array, it uses recursion and filters objects by type but this seems to be a waste of resources to me at least, using conditionals like this seems like a bad idea.
The array can be a generic type, int, string, float but not some container with mixed types.
For example
The final result for this would be
So I came up with this simple regex

while (<FILE>) {
if ($_ =~ /($regex)/) {
print "$res";
}
}
close FILE;
This finds $regex and print... (3 Replies)

re_comp
RE_COMP(3) Linux Programmer's Manual RE_COMP(3)NAME
re_comp, re_exec - BSD regex functions
SYNOPSIS
#define _REGEX_RE_COMP
#include <sys/types.h>
#include <regex.h>
char *re_comp(char *regex);
int re_exec(char *string);
DESCRIPTION
re_comp() is used to compile the null-terminated regular expression pointed to by regex. The compiled pattern occupies a static area, the
pattern buffer, which is overwritten by subsequent use of re_comp(). If regex is NULL, no operation is performed and the pattern buffer's
contents are not altered.
re_exec() is used to assess whether the null-terminated string pointed to by string matches the previously compiled regex.
RETURN VALUE
re_comp() returns NULL on successful compilation of regex otherwise it returns a pointer to an appropriate error message.
re_exec() returns 1 for a successful match, zero for failure.
CONFORMING TO
4.3BSD.
NOTES
These functions are obsolete; the functions documented in regcomp(3) should be used instead.
