Eelco Dolstra	41c45a9b31	* Store Value nodes outside of attribute sets. I.e., Attr now stores ... a pointer to a Value, rather than the Value directly. This improves the effectiveness of garbage collection a lot: if the Value is stored inside the set directly, then any live pointer to the Value causes all other attributes in the set to be live as well.	2010-10-22 14:47:42 +00:00
Eelco Dolstra	93cd5a4a13	* The << operator on values should be const.	2010-05-18 10:36:37 +00:00
Eelco Dolstra	e2d5e40f4f	* Keep track of the source positions of attributes.	2010-05-07 12:11:05 +00:00
Eelco Dolstra	ac1e8f40d4	* Use a symbol table to represent identifiers and attribute names ... efficiently. The symbol table ensures that there is only one copy of each symbol, thus allowing symbols to be compared efficiently using a pointer equality test.	2010-04-13 12:25:42 +00:00
Eelco Dolstra	4d6ad5be17	* Don't use ATerms for the abstract syntax trees anymore. Not ... finished yet.	2010-04-12 18:30:11 +00:00
Eelco Dolstra	af2a372bb0	* Update autoCallFunction() and findAlongAttrPath().	2010-04-07 15:47:06 +00:00
Eelco Dolstra	e418976107	* Option --argstr for passing string arguments easily. (NIX-75)	2007-01-14 12:32:44 +00:00
