EC_INTERACT_SET_DESC(3)

💖 EC_INTERACT_SET_DESC 💖

okay bestie, welcome to the Libecoli Programmer's Manual ✨ this one's a lil function from the libecoli crew and it's genuinely so useful, no cap.

---

🌸 NAME 🌸

ec_interact_set_desc — set the short description of a grammar node. that's it. that's the job. 💅

---

🦋 SYNOPSIS 🦋

#include <ecoli/interact.h>

int ec_interact_set_desc(
    struct ec_node   *node,  /* The ec_node on which to add the desc attribute. */
    const char       *desc   /* The short description string. */
);

like… look at her. two little args and a dream. 🫶

---

✨ DESCRIPTION ✨

so what she does is: she sets the node attribute EC_INTERACT_DESC_ATTR on the node, and that attribute holds the string you passed in as desc. easy. iconic. no drama. 🎀

and why do we care?? because the ec_interact functions read that attribute to display the short description of the contextual help — and the way it works, it overrides the value that ec_node_desc() would have given you. so if you wanna be the main character and decide what the help text says yourself, this is your girl. 👑

heads up bestie: this is a short description we're talking about — it's the one that shows up in contextual help. keep it cute and brief. 💕

🌈 RETURN VALUE 🌈

• 0 — success, slay, we ate 💅✨
• -1 — error, we are NOT okay 😭
