EC_INTERACT_SET_HELP(3)

💖 EC_INTERACT_SET_HELP 💖

okay bestie, so this one lives in the Libecoli Programmer's Manual, section 3 (that's the library-calls girlies 🫶). it's literally called ec_interact_set_help, and honestly? it's giving "one job, does it perfectly." ✨

---

✨ NAME ✨

ec_interact_set_help — set help on a grammar node. that's it, that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

#include <ecoli/interact.h>

int ec_interact_set_help(
    struct ec_node   *node,  /* The ec_node on which to add the help attribute. */
    const char       *help   /* The help string. */
);

so you pull in the header, you call the function with two things, and you're off. no cap. 🦋

---

💜 DESCRIPTION 💜

okay so here's the tea 🍓: this function sets the node attribute EC_INTERACT_HELP_ATTR on the node you hand it, and that attribute contains the string you passed in as help.

and why do we care? because the ec_interact functions use it to show contextual helps — like, when you're completing stuff, or when a parsing error pops off. so your users get a lil friendly nudge instead of just vibing in the dark. iconic behavior, honestly. 👑
