🫶 Function Documentation 🫶

struct ec_node* ec_yaml_import (const char * filename)

parse a YAML file and build an ec_node tree from it. like, literally turns your YAML into a tree. no cap 🌈

Parameters

• filename — the path to the file to be parsed. yes, an actual path to an actual file 🍓

Returns

the ec_node tree on success, or NULL on error (errno is set). and bestie, listen — the returned node must be freed by the caller with ec_node_free(). that's not optional, that's the rules 💀

int ec_yaml_export (FILE * out, const struct ec_node * node)

export an ec_node tree to a YAML formatted stream. so you take your tree and you push it out as YAML ✨

this function traverses the ec_node tree and outputs a YAML representation of the grammar structure including node type, id, help, attributes and configuration. every single one of those. the output can be used as a template or documentation for grammar definitions 🎀

Parameters

• out — the output stream where YAML content will be written. the vibe destination 💖
• node — the root node of the grammar tree to export. the main character of this operation 👑

Returns

0 on success, or -1 on error (errno is set). simple. clean. we stan 🌸
