About this release...

• The source of the body is now fully documented - maybe with the exception of a handful of parts using very black magic.

• More functions and features all over the place.

Thank You!

History

20-Aug-2000 (Lars Duening) -- Release 3.2.8

• Changed efuns:
  • add_action(): Implemented the 'short verb' feature associated with negative flag values.
  • apply(): Just returns the first argument if it is not a closure.
  • clonep(): Accepts arguments of all types.
  • command_stack(): Also returns which objects did the notify_fail()s.
  • debug_info(): DINFO_MEMORY also prints the datasize of an object.
  • debug_info(): New request DINFO_DATA.
  • inherit_list(): in non-COMPAT mode, the returned program names start with a '/'.
  • input_to(): input_to()s can now be stacked, and also accept closures for the function (this is not yet a real stacked input handling, though).
  • load_name(): also accepts strings as object designators.
  • map(): can now map an array through a mapping.
  • object_info(): OINFO_MEMORY also returns the datasize of an object.
  • printf(): prints to NPCs are sent to catch_tell().
  • present(): present(object) returns the object found, not its environment.
  • (s)printf(): object names printed in plain mode with %O now start with a leading "/".
  • (s)printf(): Fields are now always padded to their full size, even if no more data is following in the format string.
  • query_notify_fail(): A flag allows to query which object set the current error message.
  • restore_object(): Preliminary: optionally restore the object variables from a string.
  • save_object(): Preliminary: optionally return the saved object variables in a string.
  • set_connection_charset(): Now also accepts a string as charset specificator.
  • sort_array(): Now accepts extra arguments to pass to the sorting function.
  • terminal_colour(): Straightened the key recognition and added a wrapping-only mode.
  • to_string(): Now also accepts lambda closures and returns a string suitable for debugging purposes.
• Corrected efuns:
  • get_type_info(): The object a lambda closure is bound to is now returned properly.
  • limited(): When calling closures with limited eval ticks, the efun didn't make the full amount of ticks available.
  • terminal_colour(): When removing spaces due to wrapping, the efun sometimes falsely reported a "partial string too long".
  • random(): distributes the random numbers more evenly, especially over small ranges.
  • regexp(), regexplode(), regreplace(): Errors in the regular expression are raised as normal errors, and no longer printed to the user.
  • sprintf(): Is now reentrant.
  • strstr(): When given negative starting offsets, the efun no longer returns negative results.
  • transpose_array(): Can now handle variable sized sub-arrays.
  • typeof(): Now accepts literal references.
  • unique_array(): When applied on an empty array, it no longer raises an assertion.
• New efuns:
  • clones(): find and return the clones of an object.
  • copy_file(): copies a file.
  • save_value(): encodes a value into a string.
  • restore_value(): decodes a value from a string generated by save_value().
  • set_combine_charset(): Define characters to combine into strings when received in charmode.
• Master Object:
  • valid_read(), valid_write(): new function code "copy_file" to cater for the new efun.
  • valid_write(): the old function code "do_rename" (used twice) was replaced by "rename_from" and "rename_to".
  • log_error(): New argument "warn" determines if the message passed to the lfun is an error or just a warning.
  • New include_file(): generates the full pathname of a filename given in an #include directive.
  • New inherit_file(): generates the full pathname of a filename given in an inherit directive.
• Fixed Crashers:
  • Unaligned pointer access in efun functionlist(), caused by unaligned function stand-ins.
  • Multiplication of an array of allocated strings with an integer.
  • Replacing a prompt-closure from within the closure.
  • Comparison "#'f == other_type" (also !=).
  • It is no longer possible to pass destructed objects to input_to() handlers.
  • When apply() was called with an array as last argument, it didn't check the array elements for destructed objects.
  • When creating lambda closures with more than 254 constants, the compiler stored the number of values at the wrong place, clobbering one of the constants.
  • Evalstack overflows caused by intermediate results went unnoticed.
  • Calling functions with more than 255 arguments triggered a sanity guard.
  • Replacing a notify-fail closure while it is executed.
  • The default handling of telnet negotiations (answering DONT/WONT) for unsupported options like NAWS if no hooks are specified, leaked LPC stack entries, eventually overwriting memory.
  • The lambda block ({ #'return }) was compiled incorrectly, causing a 'Bad stack at F_RETURN' at the end of the lambda closure latest.
  • Efun write_file() running out of fds outside of a compilation no longer tries to raise a compilation error.
  • A failing include statement at the end of the internal lex buffer no longer causes the driver to lex invalid data, sometimes crashing while doing so.
• Language:
  • The preincrement/-decrement operators can now be applied to wide mappings ('++m[x,y]').
  • If an object is inherited virtually multiple times, a wildcarded super call ("*::") calls it only once.
  • The ->() operator also accepts the following forms:
    • x->y() where y is the name of a local variable
    • x->"y"() where "y" is a constant string
    • x->(y)() where y is an expression returning a string.
  • call_others (ie. x->(y)()) can be applied on arrays of objects, the single call results are collected in one result array.
  • New loop-construct: foreach().
  • int += type now works for type being string and float as well.
  • The operator "&" (and "&=") can now be used to intersect strings.
  • The operator "-" (and "-=") can now be used to remove characters from a string.
  • mapping1 -= mapping2 now works for mapping2 of any width, like the normal subtraction already does.
  • Indexing [..x] and [..<x] are allowed as short form of [0..x] and [0..<x].
  • The optional modifier nosave replaces the modifier static for variables - the latter is still recognized, but its use is deprecated. Similar, nosave should be used instead of static as inheritance modifier.
  • New pragma "weak_types" to turn off type checking.
  • New pragmas "pedantic" and "sloppy" turn on resp. off the treatment of certain warnings as errors.
  • Inherited functions are looked up using a breadth search.
  • Local variables can be initialized in their definition, for example:
    int i = 3;
int j = 3*i, k;
  • New preprocessor macros __DIR__ and __PATH__() to retrieve the path of the currently compiled file.
  • (void) is now accepted as empty function argument list.
  • Failure to pass enough arguments to a non-vararg simul_efun generates a warning (error in pedantic mode).
  • Redefinition of a function now checks the types of the arguments and of the return type for consistency. Same for the consistency between a function and a preceeding prototype. If a difference is detected, a warning (error in pedantic mode for arguments) is issued.
  • Preprocessor statements #else and #endif no longer accept uncommented text after the keyword. In pedantic mode, an error is raised, otherwise a warning is generated.
  • Preprocessor statement #define requires a definition after the keyword.
  • Bugfix: Newlines in literal strings in inline closures are now rejected.
  • Bugfix: #'parse_command wasn't implemented.
  • Bugfix: The expressions &(expr4[x]) and &(expr4[<x]) could generate invalid code (causing a "(lvalue) Indexing on illegal type" error) in extreme circumstances.
  • Bugfix: Compiler typechecks for "int * string" yielded "int" instead of "string" (the generated code was correct).
  • Bugfix: objects with "nomask" functions can be inherited virtually multiple times.
  • Bugfix: "*"::foo() failed if the last inherited object checked did not contain the function - even if it has been found in other objects.
  • Bugfix: ::foo() didn't find the topmost definition when confronted with virtual inherits.
  • Bugfix: In the expression ++ident the opcode for ++ was overwritten if the ident required a 2-Byte index internally. Same for --.
  • Bugfix: The preprocessor properly ignores a //-comment in the argument list for a function macro.
• Runtime:
  • If the driver is compiled for IPv6 support, the macro __IPV6__ is defined in LPC compiles.
  • Simul-efuns can now take "varargs" arguments, like in "foo(varargs mixed arg)".
  • A simul-efun call_other() finally catches ->() calls as well.
  • New pragma "no_shadow" to disallow shadows on a program.
• Other Changes:
  • The standard erq now supports the socket requests (actually it does so for some time now, it just hasn't been published).
  • Where supported, the erq supports lookup of IPv6 addresses.
  • When compiled with DEBUG and CHECK_STRINGS, the commandline option "--check-strings" checks the consistency of the shared string table with every backend cycle.
  • When compiled with DEBUG, the commandline option --check-state controls the simplistic state checks of the virtual machine in the backend loop.
  • The driver can be compiled with bison as well as with byacc.
  • New editor command 'M' to strip ^Ms from lineends.
  • The commandline argument --max-small-malloc and the corresponding configuration parameter are gone.
