2021-07-14Rewrite preprocessing of native grecs configuration files.Sergey Poznyakoff9
When external preprocessing is required, each source file is preprocessed separately. This means that if you use #include or #include_once statements, a separate copy of external preprocessor will be started for each included file. In other words, when both internal and external preprocessing is used, the order is: external first, internal next. Previous versions of grecs implemented opposite order, when one external preprocessor was started, which obtained input from the internal preprocessor. One concequence of this is that any macros defined in a configuration file are no longer visible for files included from it. * include/grecs/lex.h (grecs_parse_line_directive) (grecs_parse_line_directive_cpp): Change signature. * include/grecs/preproc.h (grecs_preproc_init) (grecs_preproc_done) (grecs_preproc_run): Remove.

2019-06-05Fix syntax checking of compound vs. scalar statements. Add assertion functions.Sergey Poznyakoff1
Up to now the parser incorrectly accepted the use of compound statement keyword in scalar context, unless the keyword description had non NULL value in the callback field. This change fixes it.

New variable GRECS_HOST_PROJECT_LDADD complements GRECS_HOST_PROJECT_INCLUDES. It provides a way to link test binaries with host project libraries. This may be useful if config.h redefines missing or defective library functions to their replacements, which are provided in third-party libraries, such as e.g. gnulib, * am/grecs.m4 (GRECS_HOST_PROJECT_LDADD): New substitution variable. * tests/Makefile.am (LDADD): Add GRECS_HOST_PROJECT_LDADD.

* tests/wordsplit.at (append + dooffs + env): Disable environment.
2018-05-22New feature: maxwordsSergey Poznyakoff2
This feature allows the user to limit the number of words returned by a call to wordsplit. When the number of words in expansion reaches the predefined limit, the rest of input line will be expanded and returned as a single last word. For example, to parse a /etc/passwd line: struct wordsplit ws; ws.ws_delim = ":"; ws.ws_maxwords = 7; ws.ws_options = WRDSO_MAXWORDS; wordsplit(str, &ws, WRDSF_NOVAR | WRDSF_NOCMD | WRDSF_DELIM | WRDSF_OPTIONS); * doc/wordsplit.3: Document the maxwords feature. * include/wordsplit.h (wordsplit) <ws_maxwords> <ws_wordi>: New members. (WRDSO_MAXWORDS): New option. * src/wordsplit.c (WSP_RETURN_DELIMS): New macro. (_wsplt_subsplit): Rewrite. (wordsplit_init0): Don't reset node list. (wordsplit_init): Initialize ws_wordi and the node list. (wsnode_insert): Correctly insert lists. (coalesce_segment): Additional safety check. (wsnode_tail_coalesce): New static function. (wordsplit_finish): Postprocess delimiters. (expvar,expcmd): Use new _wsplt_subsplit. (wordsplit_varexp): Don't try to expand delimiter nodes. (skip_delim): Remove delimiter processing. It is now done in wordsplit_finish. (scan_word): New argument 'consume_all' instructs it to consume the rest of input as one token. (wordsplit_process_list): Handle wsp->ws_maxwords setting. This also fixed a long-standing bug: quotes weren't processed in WRDSF_NOSPLIT mode. See the testcase 59 (incremental nosplit). (wordsplit_run): Rewrite. (wordsplit_free): Free node list. * tests/wordsplit.at: Update for the new wsp output format. (incremental nosplit): Expect correct output. Add tests for the maxwords feature. * tests/wsp.c (maxwords): New flag. Print the ws_wordi value as "TOTALS" at the end of each run.

2016-07-16Disable adjacent string concatenation.Sergey Poznyakoff5
The adjacent string concatenation feature doesn't work well with multiple-argument statements. The common example (found in GNU pies) is the "env" statement: env "PATH=/sbin:$PATH" "PRELOAD=true" The intent was to pass it two arguments, but in fact they get concatenated into one. To control this, the grecs_parser_options variable is introduced. If it has the GRECS_OPTION_QUOTED_STRING_CONCAT bit set, adjacent string concatenation is enabled. By default it is disabled. The GRECS_OPTION_ADJUST_STRING_LOCATIONS bit controls the way the quoted sring locations are computed. If it is set, the beginning of the string is counted at the first character after the opening double quote, and its end at the character immediately preceding the closing double quote. Otherwise, both double-quote characters are included in the location (the default). The change is backward incompatible. * doc/grecs-syntax.texi: Update. * include/grecs/parser.h (grecs_adjust_string_locations): Remove. (grecs_parser_options): New extern. * src/grecs-lex.l: QSTRING is returned only if GRECS_OPTION_QUOTED_STRING_CONCAT option is set. The GRECS_OPTION_ADJUST_STRING_LOCATIONS option controls string locus adjustment. * src/parser.c (grecs_adjust_string_locations): Remove. (grecs_parser_options): New variable. * tests/Makefile.am: Add strcat.at, stradj.at * tests/testsuite.at: Likewise. * tests/gcffmt.c: New options -strcat and -stradj * tests/stradj.at: New test case. * tests/strcat.at: New test case.
