![]() In pass 1, syntax class defns (without #:attributes decl) need to parse patterns to determine exported attributes. But to allow forward refs, stxclass references are not resolved until pass 2. Previously, this was done by just reparsing patterns in pass 2. But that means pattern expanders get expanded twice, and their expansions might not agree (eg generate-temporaries). So instead, parse in pass 1, insert "fixup" patterns to delay stxclass resolution, and resolve fixups in pass 2. Complication: a fixup pattern is assumed S, but can change to H in pass 2. |

This is the source code for the core of Racket. See "INSTALL.txt" for full information on building Racket.
To build the full Racket distribution from this repository, run make
in the top-level directory. To build minimal Racket, run make base
.
The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.
