Function Documentation

◆ fr_token_from_quote_enum_str()

fr_token_t fr_token_from_quote_enum_str	(	char const *	s,
		fr_token_t	dflt
	)

Look up a quote token by its source-identifier name.

Inverse of fr_token_to_enum_str restricted to the five quote-typed tokens (T_BARE_WORD, T_DOUBLE_QUOTED_STRING, ...) - the only forms radconf2json emits as lhs_quote / rhs_quote JSON values.

Parameters

[in]	s	enum-identifier name (e.g. `"T_DOUBLE_QUOTED_STRING"`), or `NULL`.
[in]	dflt	value to return if `s` is `NULL` or unrecognised.

Returns: the matching fr_token_t, or dflt.

Definition at line 137 of file token.c.

◆ fr_token_name()

char const * fr_token_name ( int token )

Definition at line 579 of file token.c.

Here is the caller graph for this function:

◆ fr_token_to_enum_str()

char const * fr_token_to_enum_str ( fr_token_t t )

Return the source-identifier name for a token (e.g.

"T_BARE_WORD", "T_OP_SET").

Counterpart to fr_tokens[] which returns the operator-character / human-display form (":=", "<BARE-WORD>", ...). Tooling that wants to emit grep-friendly enum identifiers (radconf2json, radmod2json) uses this.

Parameters

[in] t token to look up.

Returns: the enum-identifier name, or "T_INVALID" if t is out of range / has no symbolic entry.
