* Changes in 0.2 since 0.1
|
||
** Core
|
||
*** Names of symbols and strings are list of characters [WAS: c-string].
|
||
*** Macro expansion looks for sc-expand hook, enabling psyntax.
|
||
** Language
|
||
*** Mes now provides a subset of R6RS.
|
||
*** Mes now provides psyntax-5.9f-based syntax-case.
|
||
** Noteworthy bug fixes
|
||
*** Using values as second parameter of builtin function yields first value.
|
||
|
||
* Changes in 0.1 (since progress report #2)
|
||
** Core
|
||
*** expand_macro is now a separate function.
|
||
*** A smaller core can now compiled using BOOT=1.
|
||
The smaller core does not provide define, define-macro, or quasiquote;
|
||
these are provided from a Scheme version of implemented eval/apply.
|
||
** Language
|
||
*** Mes now provides a subset of R5RS.
|
||
*** Mes now provides let-syntax.
|
||
*** Mes now provides match.
|
||
*** Mes now provides quasisyntax, unsyntax and unsyntax-splicing.
|
||
** User interface
|
||
*** Mes now provides a REPL, run:
|
||
scripts/repl.mes
|
||
*** Mes compiler can be run as a script:
|
||
scripts/mescc.mes doc/examples/main.c
|
||
*** Macro expansion can be inspected in the REPL, e.g.:
|
||
,expand (and 0 1)
|
||
** Noteworthy bug fixes
|
||
*** Performance: scripts/mescc.mes now takes 2s to compile main.c (was 1'20").
|
||
*** Symbols are now truly unique.
|
||
* '(), #t, #f are no longer symbols.
