EC_YAML_EXPORT(3)

✨ EC_YAML_EXPORT(3) ✨

okay bestie, so we're in the Libecoli Programmer's Manual rn and this one is lowkey one of my faves 🎀 it's ec_yaml_export, and she is literally the girl who takes your whole grammar tree and turns it into a YAML glow-up. slay.

---

💖 NAME 💖

ec_yaml_export — export an ec_node tree to a YAML formatted stream. no cap, that's the whole vibe. 🌸

---

🦋 SYNOPSIS 🦋

#include <ecoli/yaml.h>

int ec_yaml_export(
    /*
     * The output stream where YAML content will be written.
     */
    FILE                   *out,
    const struct ec_node   *node   /* The root node of the grammar tree to export. */
);

so you gotta #include <ecoli/yaml.h> first (mandatory, don't skip it, that's the rules 💅), then you pass in your out stream — that's the FILE * where all the YAML content gets written ✍️ — and your node, which is the const struct ec_node * at the very top of the grammar tree you're exporting. main character node only, she handles the rest. 👑

---

🌈 DESCRIPTION 🌈

This function traverses the ec_node tree and outputs a YAML representation of the grammar structure, including:

• node type
• id
• help
• attributes
• configuration

it's giving full documentation energy fr fr 😭✨ and the output can be used as a template or as documentation for grammar definitions. so like, not just pretty — she's useful too. ate. 🍓

---

🔥 RETURN VALUE 🔥

• 0 on success 🥳
• -1 on error, and errno is set 💀

that's it, that's the deal. check your errno if it goes sideways, bestie.
