Update to KSi 3.9.0 3.9.0 ===== * Prerelease of the 4.0.0 that will be R6RS compliant. * The doc directory temporary removed from distrib. The old docs obsolete and new is not ready. * Simple R6RS-like library manager implemented. "load" function removed (use "import" syntax instead). * the ksi module system removed in a favour of new R6RS library system. * `psyntax.ss' that implemented 'syntax-case' in older revisions of the ksi, was removed. As a result, only core syntax evaluated by ksi. And ksi core is not a R6RS core :-( * '(gensym)' generate (almost) unique symbol names. As a part of generated symbol name used a 'session_id' that is initialized at startup. So, each ksi invocation has its own 'session_id'. This can help (in a future) to hardly optimize the scheme code evaluation Now the 'session_id' is initialized with random bits converted to readable string. * the "do" syntax, "delay" syntax and "force" function was removed from the ksi core. * the 'struct Ksi_Environ' and companions was rewriten almost completly. Now the environment has the name, the export list and the hashtab that maps the symbol to the value A value can be a plain value (the symbol is a variable) or a syntax value. If a symbol is bound to a syntax value, it can not be defined, assigned or used in any other case except in a intented syntax form As a special case, if a symbol is bound to a syntax value and the value is a procedure, the procedure is applyed to the form before evaluating it. (Look at 'ksi_defsyntax()' and 'ksi_compile()' for details). This mechanics is intended for low-level macros (as "define-macro!") and derived forms such as 'cond', 'case', etc. The normal sanitary macro system planned ;-). * All packed-in-the-pointer objects was removed. Such objects as 'ksi_nil', 'ksi_false' and so on, are implemented as a pointers to a memory location that allocated when initializing the ksi library. Do not be suprized the error if you use its before calling `ksi_init()'. * The 'struct Ksi_Char' (added) is internal representation of a character now. (first step to unicode). * the GMP library used for exact arithmetics now. As a result, the ksi supports the exact rational numbers now. * The short integers was removed. Bignums are the only exact numbers now. And predefined constans 'ksi_zero', 'ksi_one', etc was removed too. (Use 'ksi_long2num()' in C code) * A flonum has real and imag part always, and so, a flonum is a complex number now. But 'real?' returns #t if imaginary part is zero and 'number->string' do not print "+0.0i" if imaginary part is zero. (This is not what R6RS requires but alas, it is the ksi) * balanced comments are writen within "#| |#" construct now (not with "#! !#" as in the previous revisions of the ksi). The sequence "#!<identifier>" used for the reader directives now. In addition, to support the scheme scripts, the sequence "#! " (note whitespace) and "#!/" in the very begin of a file supposed as a one-line comment. * Reader now case-sensitive by default, as required R6RS. Use the "#!fold-case" directive to switch the reader to the case-insensitive mode, and "#!no-fold-case" to switch to the case-sensitive mode back. * By default, the reader parses postfix keyword notation, such as "key:". "#!keyword-prefix" switches the reader to prefix mode, such as ":key", and "#!keyword-postfix" switches the reader back to postfix mode. * By default, the reader do not parses the old ksi keyword notation, such as "#:key". Use the "#!keyword-sharp" directive to switch the old mode on, and "#!no-keyword-sharp" to switch off. * "#!r6rs" directive switches the reader to the R6RS mode, and "#!ksi" directive switches the reader to the default mode back. In the r6rs mode: -- the keywords are not parsed at all; -- any sequence that starts with digit, '+', '-', '.', tried to be parsed as a number and, if cannot, exception raised. Otherwice the sequence is parsed as a symbol. In the ksi mode: -- the keywords are parsed; -- any sequence, that starts with digit, or '+', '-', '.' folowed by digit, tried to be parsed as a number and, if cannot, exception raised. Otherwice the sequence is parsed as a symbol. So, the sequence like '+x' is parsed as symbol in the ksi mode, but raise exception in the r6rs mode. Note that in the previous revisions of the ksi, any sequence, that cannot be parsed as a number, was considered as a symbol (never exception raised). 3.5.1 ===== * bugfixes * (Windows) ksi dll name has version info now. 3.5.0 ===== * code refactoring
