🧚 Configuration Schema 🧚

schema re_lex {
    list patterns  {
        description "The list of patterns elements.";

        dict  {
            description "A pattern element.";

            string pattern  {

🎀 Function Documentation 🎀

💜 struct ec_node* ec_node_re_lex (const char * id, struct ec_node * child) 💜

Create a regex-based lexer node. Iconic behavior, honestly.

This node tokenizes the input using regular expressions added with ec_node_re_lex_add() and passes the resulting tokens to the child node.

Parameters:

• id — The node identifier.
• child — The child node. It is consumed and will be freed when the parent is freed, or immediately on error.

Returns:

• The node, or NULL on error (errno is set).

---

🌸 int ec_node_re_lex_add (struct ec_node * gen_node, const char * pattern, int keep, const char * attr_name) 🌸

Add a token pattern to a regex lexer node. Slay.

Parameters:

• gen_node — The regex lexer node.
• pattern — The regular expression pattern for matching tokens.
• keep — If non-zero, include matched tokens in the output; if zero, discard them.
• attr_name — Optional attribute name to attach to matched tokens, or NULL.

Returns:

• 0 on success, -1 on error (errno is set).
