Eelco Dolstra 1610444671 * Conditions, string equality. 2003-11-01 19:15:08 +00:00
Eelco Dolstra 1b4184ccbb * Let syntax. 2003-11-01 19:10:41 +00:00
Eelco Dolstra a2a9bacd82 * Filter the substitution list when descending into a recursive 
attribute set.
 2003-11-01 19:10:19 +00:00
Eelco Dolstra 9210d4d530 * Working evaluator. 
* Mutually recursive attribute sets.
* Print evaluator efficiency statistics.

Eelco Dolstra f1c1a3c97f * Allow empty attribute (argument) sets. 2003-10-31 12:21:01 +00:00
Eelco Dolstra 7db08cc924 * Use SGparseString() instead of SGparseFile() because the latter is 
buggy.  It fails to clear an internal variable (SG_textIndex)
  between invocations, so it can be called only once during a program
  execution.

Eelco Dolstra 403cb9327f * Factor out evaluation into a separate file. 2003-10-30 16:48:26 +00:00
Eelco Dolstra 9f8f39aa3c * Clean up the imploded parse tree. Quotes around strings are 
removed, paths are absolutised relative to the path containing the
  expression we just parsed, and integer literals are converted to
  actual integers.
 2003-10-30 16:18:40 +00:00
Eelco Dolstra e537844f4e * Bottomup rewrite function. 2003-10-30 16:11:24 +00:00
Eelco Dolstra 442b09ea33 * Don't use a search path. 2003-10-30 16:10:56 +00:00
Eelco Dolstra 933b3f677d * Attribute selection operator. 2003-10-30 16:10:20 +00:00
Eelco Dolstra b95a3dc45b * Basic grammar and parser for the Fix language. We use libsglr and 
friends to do the parsing.  The parse table is embedded in the Fix
  executable using bin2c, which converts an arbitrary file into a C
  character array.

Eelco Dolstra 4d728f6a36 * Forked new version of Fix. 2003-10-29 15:05:18 +00:00
