* Revert "object: rename"Gravatar Peter McGoron 2024-09-273-12/+8
| | | | | | | | This makes things much slower for questionable benefit. A better version might use a hash table. A better interpreter would use some form of partial evaluation to optimize the EQ? chain. This reverts commit 4acea69841ad62ec5d46eb565bbb5d98f84b3d38.

* readtable: simplifyGravatar Peter McGoron 2024-09-082-242/+134
| | | | | | | | | After taking a look at the R7RS syntax and how Chicken parses directives, I realized that it's easier to have "#!", "#\\", etc. parse identifiers instead of baking in trie actions. This is slightly slower but completely removes the trie concept from the readtable, which simplifies the implementation and removes many corner cases involving combining readtables with different action types.

* readtable: Normalize character handled by ACTIONs at the end ofGravatar Peter McGoron 2024-09-071-8/+15
| | | | | | | | | | | | sequences. Previously, if "#true" and "#t" were in the readtable as sequences, the string "#true" would call "#true"'s EXEC function after reading "e", but it would call "#t"'s EXEC function after reading a character after "t" (which could be EOF). The new behavior normalizes everything so that the ACTIONs read the character after the sequence.

* Readtable: fix propagation of default handlers in trie pathsGravatar Peter McGoron 2024-09-071-43/+56
| | | | | | | | | | | | | Previous version did (ACTION 'UPDATE (CDR REST) ACTION) when a new action had to be made. This caused default actions to propagate through the trie. While this isn't bad (it causes #TRU to be equal to #TRUE when that was the last prefix in the tree), it can cause unexpected errors at runtime, and no program should ever depend on its behavior. The current solution is to make a new PASS readtable with a default error action.
