7c8fc30541 b2/boom.c (usage): -Q wasn't mentioned; explain -q and -Q 2012-05-23 15:14:58 -03:00

db279b7920 b2/subex.c (compose): use stralloc_n instead of open-coding its functionality 2012-05-23 14:18:02 -03:00

c9bd26a34d b2/Makefile: generate dependencies also for YACC- and LEX-generated files 
We need explicit rules to compile lex.yy.c and y.tab.c for the relaxed
CFLAGS. However, this means that the implicit rule was not used and
therefore no dependencies were generated.

4f142c1250 b2/: for consistency, make "break/continue $" equivalent to "break/continue" 
Plus a bit of code simplification.

694d48b56a b2/: make the match name after "break" and "continue" optional 
If the name is omitted, we jump back / out of the current block.

bb809b0d6c b2/: make "again" include the match; make "break" pop the stack 2012-05-22 15:29:27 -03:00

2ce2da5c30 b2/subst.c (resolve_jump): use pointer comparison instead of strcmp 
Both come from "unique".

21702781bc b2/: use re_nsub instead of maintaining our own equivalent 
We still need to count parentheses in prepare_re for the current index
into "units", but the rest can ue re_nsub.

148d5e85ac b2/: regexec puts first substring into pmatch[1] and not pmatch[0] 
Also clean up the hard-coded number of matches.

3d2eca34ff b2/: meta-variable $ for "previously matched variable" 
We need this for iterative processing of FN.

2946b830f1 b2/subst.c (prepare_re): fail on bad (#unit) syntax instead of ignoring 2012-05-22 12:07:41 -03:00
Werner Almesberger
d2171eba47 b2/: add "ignore" keyword for substitution rules 
This allows us to decide in the project-specific rules how to indicate
DNP/NC/DNS/... parts. In the original BOOM, F1 == NC was hard-coded.

2014e6053e b2/eval.c (decode_mult): also support "G" prefix 
Not that we'd need giga-anything anytime soon, but since all the rest
also recognizes G, we support it here for consistency.

061e8f5872 b2/: rename "name" field in struct value to more generic "s", for better sharing 2012-05-21 14:44:33 -03:00

fdac542592 b2/: add relop to struct param, in preparation of merge with struct var 2012-05-21 14:35:51 -03:00

3ad6c2c44b b2/: move all error handling from subex to subst 
This makes checking of variables more strict: a variable can only
be used in the right -hand side of an assignment if it has been
assigned by an unconditional predecessor or if it has been matched
by a parent.

Things that wouldn't work anymore:

REF=X* {
	FN=*V { X=Y }
	Z=$X	/* we can't be sure X=Y was taken */
}

FN=*R {
	X=$REF	/* no previous use of REF */
}

a34702cd8d b2/: move relational operators to relop.[ch] (for sharing) 
This also fixes a bug in dump_one_field, which switched > and >=

99e5777448 b2/: finish unit handling and move most of its processing to the match side 
The ${foo#unit} syntax didn't really make sense because it created
a large number of potential error conditions on the assignment side
and didn't help with finding compatible fields.

With all this moved to the match side, an invalid syntax simply causes
a mismatch.

1394c6b61c b2/: make top-level hierarchy item an action, not just a rule 
This allows the definition of optional global fields. For now, we (ab)use
this for FP (footprint).
