2010-10-24 * Keep attribute sets in sorted order to speed up attribute lookups.Eelco Dolstra1-2/+5
* Simplify the representation of attributes in the AST. * Change the behaviour of listToAttrs() in case of duplicate names.
2010-10-22 * Store Value nodes outside of attribute sets. I.e., Attr now storesEelco Dolstra1-3/+4
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.
2010-05-18 * The << operator on values should be const.Eelco Dolstra1-1/+1
2010-05-07 * Keep track of the source positions of attributes.Eelco Dolstra1-1/+1
2010-04-13 * Use a symbol table to represent identifiers and attribute namesEelco Dolstra1-2/+2
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.
2010-04-12 * Don't use ATerms for the abstract syntax trees anymore. NotEelco Dolstra1-2/+2
finished yet.
2010-04-07 * Update autoCallFunction() and findAlongAttrPath().Eelco Dolstra1-6/+8
2007-01-14 * Option --argstr for passing string arguments easily. (NIX-75)Eelco Dolstra1-0/+32
