EC_NODE_RE_SET_REGEXP(3)

✨ NAME ✨

okay bestie, welcome to EC_NODE_RE_SET_REGEXP(3) from the Libecoli Programmer's Manual 🫶 — this one's a tiny little function and honestly? iconic.

ec_node_re_set_regexp — Set the regular expression on a regex node. 💅 That's it. That's the whole job. She sets the regexp. Periodt.

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header:

#include <ecoli/node_re.h>

and then here's the whole signature, exactly as it is, no cap:

int ec_node_re_set_regexp(
    struct ec_node   *node,  /* The regex node. */
    /*
     * The regular expression pattern. It is duplicated internally.
     */
    const char       *re
);

so node is the regex node (the thing you're blessing with a pattern), and re is the regular expression pattern itself. and listen — it gets duplicated internally, so the function makes its own lil copy, you don't gotta worry about keeping your string alive. ✨
