💖 EC_NODE_RE_LEX_ADD(3) 💖

okay bestie, welcome to the Libecoli Programmer's Manual — this is the page for ec_node_re_lex_add, and yes it's a 3, so it's a library function, we're in C territory, hydrate and let's go 🫶

---

✨ NAME ✨

ec_node_re_lex_add — bestie, this is literally the function that adds a token pattern to a regex lexer node. that's the whole job. that's the assignment. slay 💅

---

🌸 SYNOPSIS 🌸

#include <ecoli/node_re_lex.h>

int ec_node_re_lex_add(
    struct ec_node   *gen_node,   /* The regex lexer node. */
    /*
     * The regular expression pattern for matching tokens.
     */
    const char       *pattern,
    /*
     * If non-zero, include matched tokens in the output; if zero, discard
     * them.
     */
    int               keep,
    /*
     * Optional attribute name to attach to matched tokens, or NULL.
     */
    const char       *attr_name
);

so you're passing in gen_node — that's the regex lexer node itself, the main character 👑 — then pattern, which is the regular expression pattern used for matching tokens, then keep, and attr_name. four things. you got this fr fr.

🔥 RETURN VALUE 🔥

• 0 — success!! you ate, no crumbs, we love to see it ✨
• -1 — error 😭 and errno is set, so go check it, the answer is in there, i promise

not me being dramatic but like — always check the return value, bestie. -1 is not a vibe, it's a warning 🚨
