Enumeration Type Documentation

enum state_token_en

The state file has simplistic lispy lexical tokens.  Its lexer gives
   a linked list of struct state_token_st, through the peek_state_token
   function.  Lexical tokens are consumed with next_state_tokens.

The lexical kind of each lispy token.

Enumerator:

STOK_NONE
STOK_INTEGER
STOK_STRING
STOK_LEFTPAR
STOK_RIGHTPAR
STOK_NAME

static struct state_token_st* read_a_state_token ( )

staticread

Our token lexer is heavily inspired by MELT's lexer, and share some
   code with the file gcc/melt-runtime.c of the GCC MELT branch!  We
   really want the gengtype state to be easily parsable by MELT.  This
   is a usual lispy lexing routine, dealing with spaces and comments,
   numbers, parenthesis, names, strings.

Following routines are useful for serializing datas.
 *
 * We want to serialize :
 *          - typedefs list
 *          - structures list
 *          - param_structs list
 *          - variables list
 *
 * So, we have one routine for each kind of data.  The main writing
 * routine is write_state.  The main reading routine is
 * read_state.  Most writing routines write_state_FOO have a
 * corresponding reading routine read_state_FOO.  Reading is done in a
 * recursive descending way, and any read error is fatal.
