C++ (Cpp) lexer_matches Examples

Example #1

File: lexer.c Project: whoverse/libwholex

token_t* lexer_nextif(lexer_state_t* lex, token_types_t tokentype) {
    if ( lex->error ) return NULL;

    if ( lexer_matches(lex, tokentype) ) {
        return lexer_next(lex);
    }

    return NULL;
}

Example #2

File: lexer.c Project: whoverse/libwholex

token_t* lexer_nextif_special(lexer_state_t* lex, const char* token) {
    if ( lex->error ) return NULL;

    if ( lexer_matches(lex, special_token) ) {
        if ( strcmp((char*) lexer_cur(lex)->value, token) == 0 ) {
            return lexer_next(lex);
        }
    }

    return NULL;
}

Example #3

File: parser.c Project: stonegao/mirb

struct node *parse_argument(struct compiler *compiler)
{
    struct node *result = alloc_node(compiler, N_ARGUMENT);

    result->left = parse_expression(compiler);
    result->right = 0;

    if(lexer_matches(compiler, T_COMMA))
        result->right = parse_argument(compiler);
    else
        result->right = 0;

    return result;
}
