2009-09-12 Date Version 0.8.0 released
|
||||
======================================
|
||||
|
||||
Bugfixes
|
||||
--------
|
||||
- fixed a small bug that caused the compiler to not report unused
|
||||
overloaded symbols
|
||||
- fixed a small bug concerning symbol overloading
|
||||
- fixed a typo: it's "ambiguous", not "ambigious" ;-)
|
||||
- the compiler now detects recursive include files
|
||||
- ``system.card`` should work again
|
||||
- ``items`` for ``set[char]`` and ``array[char, T]`` should work now
|
||||
|
||||
|
||||
Additions
|
||||
---------
|
||||
|
||||
- implemented generic types and two phase symbol lookup in generic routines
|
||||
- template parameters can now be real types
|
||||
- implemented generalized raw string literals: ``ident"abc"`` is a shortcut for
|
||||
``ident(r"abc")``
|
||||
- in overloading resolution iterators are separated from procs; iterators now
|
||||
can have the same name+signature as procs
|
||||
- symbol lookup in templates can be affected by the new ``bind`` keyword
|
||||
- the compiler now accepts a ``--no_main`` switch for better link
|
||||
interoperability with other compiled languages
|
||||
- implemented tuple unpacking in ``var`` sections
|
||||
- the code generator emits ``default: __assume(0);`` for Visual C++
|
||||
(for optimization)
|
||||
- the compiler now checks if a proc has side effects; procs that are declared
|
||||
to have no side effects are rejected if the compiler cannot verify this
|
||||
- the format operator ``strutils.%`` now supports ``$#`` for automatic argument
|
||||
counting
|
||||
- implemented ``strutils.join``
|
||||
|
||||
|
||||
Changes affecting backwards compability
|
||||
---------------------------------------
|
||||
|
||||
- two phase symbol lookup is performed in generic routines
|
||||
- ``bind`` is now a reserved word; ``exception`` is no reserved word anymore
|
||||
- abstract types have been renamed to distinct types; thus
|
||||
``distinct`` is now a reserved word; ``abstract`` is no reserved word anymore
|
||||
- ``system.openFile`` deprecated: use ``system.open`` instead
|
||||
- ``system.closeFile`` deprecated: use ``system.close`` instead
|
||||
- ``strutils.replaceStr`` deprecated: use ``strutils.replace`` instead
|
||||
- ``strutils.deleteStr`` deprecated: use ``strutils.delete`` instead
|
||||
- ``strutils.splitSeq`` deprecated: use ``strutils.split`` instead
|
||||
- ``strutils.splitLinesSeq`` deprecated: use ``strutils.splitLines`` instead
|
||||
- ``strutils.parseFloat`` does not accept an additional ``start`` parameter
|
||||
anymore
|
||||
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
- the manual has been improved
|
||||
|
||||
|
||||
|
||||
2009-06-08 Version 0.7.10 released
|
||||
==================================
|
||||
|
||||
Nimrod version 0.7.10 has been released! Get it `here <./download.html>`_.
|
||||
|
||||
Bugfixes
|
||||
--------
|
||||
|
||||
- fixed bug #374441, #376113
|
||||
- the posix module works for Mac OS X again
|
||||
- returning an array should now work
|
||||
- fixed a serious bug in several parsers: the cached buf pointer
|
||||
must be updated after a reallocation of the buffer
|
||||
- fixed a CSS bug that kept Firefox from rendering parts of
|
||||
the generated documentation properly
|
||||
- fixed a bug concerning evaluation of command statements
|
||||
- overloading of ``inc``, ``dec``, ``pred``, ``succ`` should now work
|
||||
- ``removeDir`` now works as the documentation says: it even removes
|
||||
directories that are not empty
|
||||
|
||||
|
||||
Additions
|
||||
---------
|
||||
|
||||
* zero argument templates/macros can now be invoked without ``()``,
|
||||
because this is not ambiguous
|
||||
* new modules in the library:
|
||||
- ``dynlib``: load symbols from a shared library
|
||||
- ``python``: wrapper for the Python programming language
|
||||
- ``tcl``: wrapper for the TCL programming language
|
||||
* added ``system.max``, ``system.min`` for open arrays
|
||||
* added ``system.each`` built-in
|
||||
* added ``os.getFilePermissions``, ``os.setFilePermissions``,
|
||||
``os.inclFilePermissions``, ``os.exclFilePermissions``
|
||||
* the ``dynlib`` import mechanism now supports a flexible versioning scheme:
|
||||
|
||||
.. code-block:: nimrod
|
||||
|
||||
proc Tcl_Eval(interp: pTcl_Interp, script: cstring): int {.cdecl,
|
||||
importc, dynlib: "libtcl(8.5|8.4|8.3|8.2|8.1).so.(1|0)".}
|
||||
|
||||
* implemented ``abstract`` types
|
||||
|
||||
|
||||
Changes affecting backwards compability
|
||||
---------------------------------------
|
||||
|
||||
- the organization within the ``lib`` folder now reflects the documentation;
|
||||
as a result old configuration files need to be updated
|
||||
- ``abstract`` is now a reserved keyword
|
||||
- ``echo`` is now a built-in macro that accepts a variable numer of
|
||||
arguments of different types (and calls ``$`` for the arguments that need
|
||||
it); as a result it cannot be overloaded anymore
|
||||
- ``where`` is no keyword anymore
|
||||
- installation on UNIX produces a release version of the compiler
|
||||
|
||||
|
||||
2009-05-08 Version 0.7.8 released
|
||||
=================================
|
||||
|
||||
Nimrod version 0.7.8 has been released!
|
||||
Apart from bugfixes and added libraries the biggest change is that Nimrod
|
||||
now has a new memory manager which:
|
||||
|
||||
- interacts much better with the GC
|
||||
- uses less memory
|
||||
- is faster than the old memory manager (``dlmalloc``)
|
||||
- releases memory back to the operating system
|
||||
|
||||
|
||||
Bugfixes
|
||||
--------
|
||||
|
||||
- generics are now processed earlier in the pipeline; thus
|
||||
generics can be used within macros
|
||||
- changed bootstrapping in ``koch.py`` and ``boot.nim`` to fix
|
||||
bug #369607
|
||||
- the compiler now checks that ``yield`` is used inside a loop
|
||||
- fixed a bug in the evaluation code for ``system.len``,
|
||||
``system.setlen`` and ``system.newSeq``
|
||||
- overflow checking for ``newSeq`` fixes a security issue
|
||||
|
||||
|
||||
Additions
|
||||
---------
|
||||
|
||||
- new module: ``parsecsv`` for parsing CSV files
|
||||
- new module: ``xmlgen`` for generating XML or HTML
|
||||
- new module: ``osproc`` for OS process communication
|
||||
- added ``math.TRunningStat`` object and its methods
|
||||
- added ``strutils.validIdentifier``
|
||||
- the reStructuredText parser now supports the ``container`` directive that
|
||||
translates to the HTML ``div`` element
|
||||
- the ``cgi`` module registers a handler, so that stack traces contain the
|
||||
HTML ``<br />`` element making CGI applications easier to debug
|
||||
- added the ``cgi.decodeData`` iterator
|
||||
- ``copy`` and ``newString`` can now be evaluated at compile time. As a
|
||||
result more procedures from the ``strutils`` module can be evaluated at
|
||||
compile time.
|
||||
- ``macros.error`` now prints a stack trace
|
||||
- Nimrod now supports the Boehm-Demers-Weiser conservative garbage collector:
|
||||
The ``--gc:boehm`` command line switch activates it. However, the native
|
||||
Nimrod collector is faster!
|
||||
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
- Nimrod's abstract syntax trees are now documented in the
|
||||
`macros <macros.html>`_ module. Unfortunately the documentation is still
|
||||
incomplete.
|
||||
|
||||
|
||||
2009-04-22 Version 0.7.6 released
|
||||
=================================
|
||||
|
||||

|
||||
also been implemented.

Additions
|
||||
---------
|
||||
- implemented the passing of a code-block to the last parameter of a
|
||||
template/macro:
|
||||
|
||||
.. code-block:: nimrod
|
||||
|
||||
template withFile(f, filename, mode: expr,
|
||||
actions: stmt): stmt =
|
||||
block:
|
||||
var f: TFile
|
||||
if openFile(f, filename, mode):
|
||||
try:
|
||||
actions
|
||||
finally:
|
||||
closeFile(f)
|
||||
else:
|
||||
quit("cannot open: " & filename)
|
||||
|
||||
withFile(txt, "ttempl3.txt", fmWrite):
|
||||
txt.writeln("line 1")
|
||||
txt.writeln("line 2")
|
||||
|
||||
- new pragma ``deprecated`` can be used to mark deprecated identifiers
|
||||

|
||||
``strutils`` module
|
||||
- nice ``=~`` template operator for the ``regexprs`` module
|
||||
- the scoping rules for ``for``, ``while``, ``if``, ``case`` changed
|
||||
in a subtle way to support the new ``=~`` template
|
||||
- added common regular expressions for regexprs
|
||||
- ``posix`` module now declares socket stuff
|
||||
- new module: ``cgi`` for creating CGI applications
|
||||

|
||||
parsing *dirty* HTML
|
||||
- new module: ``web`` for retrieving web pages
|
||||
- new module: ``md5`` for computation of MD5 checksums
|
||||
- new wrappers: ``mysql``, ``sqlite3``, ``libcurl``
|
||||
|
||||
|
||||
Changes affecting backwards compability
|
||||
---------------------------------------
|
||||
|
||||
- ``strutils.findSubStr``, ``strutils.findChars`` deprecated:
|
||||
use ``strutils.find`` instead
|
||||
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
- The library is now divided into *pure libraries*, *impure libraries*
|
||||
and *wrappers*.
|
||||
|
||||
|
||||
2009-01-22 Forum added
|
||||
======================
|
||||
We now have a `forum <http://www.ethexor.com/heimdall>`_ where you can discuss
|
||||
Nimrod.
|
||||
|
||||
|
||||
2009-01-07 Version 0.7.4 released
|
||||
=================================
|
||||
|
||||
Nimrod version 0.7.4 has been released!
|
||||
|
||||
Bugfixes
|
||||
--------
|
||||
|
||||
- installation on Windows should work now if the directory contains spaces
|
||||
- the documentation generator now only renders documentation comments
|
||||
- ``\`` is allowed for operators as the manual says
|
||||
- in rare cases, the index check has been optimized away, even though
|
||||
it would have been necessary
|
||||
- several bugfixes for tuple types
|
||||
|
||||
Additions
|
||||
---------
|
||||
|
||||
- added an ``unicode`` module for UTF-8 handling
|
||||
- added ``hostOS`` and ``hostCPU`` magics to the ``system`` module
|
||||
- ``system.echo`` now accepts multiple arguments
|
||||
- added optimization: in some cases inlining of iterators now produces
|
||||
substantially better code
|
||||
- added whole program dead code elimination
|
||||
- the magic ``$`` operator now works for enumerations
|
||||
- in ``const`` sections advanced compile time evaluation is done:
|
||||
|
||||
.. code-block:: nimrod
|
||||
proc fac(n: int): int =
|
||||
if n <= 1: return 1
|
||||
else: return n*(fac(n-1))
|
||||
|
||||
const
|
||||
z = fac(3) # computes 6 at compile time
|
||||
|
||||
Changes affecting backwards compability
|
||||
---------------------------------------
|
||||
|
||||
- renamed ``in_Operator`` to ``contains``: ``in`` is now a template that
|
||||
translates to ``contains``
|
||||
- changed ``strutils.quoteIfSpaceExists`` to ``strutils.quoteIfContainsWhite``
|
||||
- the parser is now much more picky about missings commas, etc. If this affects
|
||||
your code too much, try to run your code through the pretty printer.
|
||||
- the ``macros`` API is no longer part of the ``system`` module, to use this
|
||||
API you now have to import the ``macros`` module
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
- added a tutorial
|
||||
|
||||
|
||||
|
||||
2008-12-12 Version 0.7.2 released
|
||||
=================================
|
||||
|
||||
Nimrod version 0.7.2 has been released! This is a bugfix release. This most
|
||||
important fix is that Nimrod now works again on AMD64 (x86_64) processors. No
|
||||
new features have been implemented.
|
||||
|
||||
|
||||
2008-11-16 Version 0.7.0 released
|
||||
=================================
|
||||
|
||||
Nimrod version 0.7.0 has been released!
|
||||
Changes:
|
||||
* various bug fixes, too many to list them here
|
||||
* the installation for UNIX-based systems does not depend on Python any longer
|
||||
* the ``koch.py`` script now works with older Python versions (including 1.5.2)
|
||||
* changed integer operations and conversions rules
|
||||
* added ``GC_ref`` and ``GC_unref`` procs
|
||||
* sequences now need to be constructed with the ``@`` operator. This leads to
|
||||
less ambiguities.
|
||||
* the compiler now uses less memory and is much faster
|
||||
* the GC is now much faster
|
||||
* new bindings: zlib, SDL, Xlib, OpenGL, ODBC, Lua
|
||||
* the generated C code is much faster to optimize with GCC
|
||||
* new libraries: streams, zipfiles
|
||||
* the Nimrod compiler has been ported to FreeBSD: it should work on
|
||||
other BSD's too
|
||||
|
||||
|
||||
2008-08-22 Version 0.6.0 released
|
||||
=================================
|
||||
|
||||
Nimrod version 0.6.0 has been released!
|
||||
**This is the first version of the compiler that is able to compile itself!**
|
||||
A nice side-effect from this is that a source-based installation does not
|
||||
depend on FreePascal any longer.
|
||||
|
||||
Changes:
|
||||
* various bug fixes, too many to list them here
|
||||
* cleaned up the type system: records are now superfluous and not
|
||||
supported anymore
|
||||
* improved the performance of the garbage collector
|
||||
* new modules in the library:
|
||||
- ``parseopt``: a simple to use command line parser
|
||||
- ``hashes``: efficient computation of hash values
|
||||
- ``strtabs``: efficient mapping from strings to strings
|
||||
- ``parsecfg``: an efficient configuration file parser
|
||||
* macros and compile-time evaluation implemented (however, still experimental)
|
||||
* generics implemented (however, still experimental)
