* Hash-bang support for .tl files.Kaz Kylheku2015-07-021-1/+10
| | | | | | | | | | | | | | | | * parser.c (read_eval_stream): New boolean argument to request hash bang support. * parser.h (read_eval_stream): Declaration updated. * eval.c (sys_load): Pass new thid argument to read_eval_stream, to decline hash bang support. * match.c (v_load): Likewise. * txr.c (txr_main): Request hash bang support from read_eval_stream. Thus files referenced from the txr command line can have a #! line, which is ignored.
* * parser.c (parser_mark): Do not mark p->syntax_tree ifKaz Kylheku2015-06-191-1/+2
| | | | | its value is nao. Introduced on 2015-06-10, "Error handling improvement in read".
* @(load) and @(include) now load Lisp code.Kaz Kylheku2015-06-121-0/+30
| | | | | | | | | | | * match.c (v_load): Check txr_lisp_p flag coming out of open_txr_file and handle the Lisp case usin read_eval_stream. * parser.c (read_eval_stream, get_parser, parser_errors): New functions. * parser.h (read_eval_stream, get_parser, parser_errors): Declared.
* Preparing for lisp loading.Kaz Kylheku2015-06-101-7/+58
| | | | | | | | | | | | | * parser.c (open_txr_file): Rewritten to take new argument which indicates whether to treat an unsuffixed file as TXR or TXR Lisp, and is updated to indicate which is the case by looking at the suffix. * parser.h (open_txr_file): Declaration updated. * match.c (v_load): Follow change in open_txr_file. * txr.c (txr_main): Likewise.
* Error handling improvement in read.Kaz Kylheku2015-06-101-4/+6
| | | | | | | | | | * parser.y (spec): New grammar production to handle the cases that SECRET_ESCAPE_E is not followed by anything (the input ends before any object is scanned, or there is no input token which starts an object). * parser.c (lisp_parse): Deal with EOF indication from parser (the syntax_tree member of parser_t set to nao).
* * parser.c (stream_parser_hash): New static variable.Kaz Kylheku2015-06-071-7/+47
| | | | | | | | | | | | | | | | | | (parser_mark): Mark parser and primer members. (parser, ensure_parser): new argument: primer. (get_parser_impl, ensure_parser): New static functions. (prime_parser): New function. (lisp_parse): Multiple calls to this function on the same stream now logically continue the parse, not resetting the line number to 1. (parse_init): Initialize and gc-protect stream_parser_hash. * parser.h (parser_t): New members, primer and parser. (prime_parser): Declared. (parser): Declaration updated. * parser.y (parse): Now responsible for calling prime_parser.
* * match.c (v_load): Call parse_once rater than parse.Kaz Kylheku2015-06-071-2/+2
| | | | | | | | | | | | | * parser.c (regex_parse): Likewise. * txr.c (txr_main): Likewise. * parser.h (parse): Declaration updated. (parse_once): Declared. * parser.y (parse_once): New function, same as old parse implementation. (parse): Becomes one argument function which works with a previously initialized parser and continues the parse.
* * Makefile (LISP_TO_C_STRING): Strip comments, but not comment lines,Kaz Kylheku2015-05-071-4/+5
| | | | | | | | | | | | | | | | | | so line numbers don't change. * eval.c (eval_init): Fix registrations of lisp-parse and read. * lisplib.c (place_instantiate): Give name to parsed string stream using new lisp_parse argument. * parser.c (lisp_parse): Takes new argument to override name. * parser.h (lisp_parse): Declaration updated. * txr.c (txr_main): Call lisp_parse with four args, defaulting the new one. * txr.1: Documented new argument.
* * parser.c (open_txr_file, regex_parse, lisp_parse): FunctionsKaz Kylheku2014-12-211-0/+77
| | | | | | | moved here from parser.l. * parser.l (open_txr_file, regex_parse, lisp_parse): Functions moved from here to parser.c.
* * Makefile (OBJS): Add parser.o.Kaz Kylheku2014-12-211-0/+89
* parser.h (parser_s): Declared. (parse_init): Declaration removed. (parser_l_init): Declared. * parser.l (parse_init): Function renamed to parser_l_init. * parser.c: New file.
