jEdit performance workaround

Runs slow on my Ubuntu, but if I make

jEdit global options -> Appearance -> Show the systray icon to OFF.

it runs as fast as native. Strange bug on Gnome 3.

FreePascal status

Unicode is supported by LCL (Lazarus) via UTF-8. There are several functions to convert from system encoding strings (codepage on Windows) to utf-8 strings.

According to the docs, fpc supports MacOSX 32 and 64-bit, iOS targets.http://wiki.freepascal.org/LCL_Unicode_Support

Digitalmars D version 2 a fresh look

A few years ago I spotted the D language and was quite impressed by it, although the division of standard library, the development of a new 2.0 version and the stale state of many libraries stopped from active usage of it.

Now a lot of things changed, the 2.0 version is more or less stable and there's a GNU D compiler for this version and it's actively developed/supported, and even planned to be maintained as one of the GNU Compiler Collection. I wish it come true.

Having reviewed the specs for the D 2.0 I should admit that the language is engineered VERY thoroughly, with many features I was missing in Java and C++, it's clean and rich at the same time.

At first I was planning to use LDC compiler for D 1.0 because failed to compile GDC for MacOSX, but then I decided to start coding something useful for Linux only to study the language, and probably later there will be a viable implementation for MacOSX. The official implementation (DMD) can compile only 32-bit binaries for MacOSX, that's why I'm concerned on alternative implementations like GDC, LDC2...

LDC under ubuntu 11.10 one more try

Installed through apt llvm-2.9, downloaded trunk LDC, executed ccmake, and added -ldl to LIBCONFIG_LDFLAGS. Successfully built!

Build tango, and adjusted /usr/local/etc/ldc.conf:

// This configuration file uses libconfig.
// See http://www.hyperrealm.com/libconfig/ for syntax details.

// Special macros:
// %%ldcbinarypath%%
//  - is replaced with the path to the directory holding the ldc executable

// The default group is required
default:
{
    // 'switches' holds array of string that are appends to the command line
    // arguments before they are parsed.
    switches = [
        "-I/usr/local/include/d",
        "-I/usr/local/include/d/tango/core/vendor",
        "-L-L/usr/local/lib",
        "-L-ltango-ldc",
        "-d-version=Tango",
        "-defaultlib=tango-ldc",
        "-debuglib=tango-ldc"
    ];
};

LDC under Ubuntu 11.10

Install llvm 2.9 from repo, ccmake, specify path to llvm-config tool: /usr/lib/llvm-2.9/bin/llvm-config, finally was unable to build from sources. :(

D programming under MacOS X 10.6, LDC

See http://dsource.org/projects/ldc/wiki/OSXBuildInstructions

Macports to install llvm package (2.9). Then get the latest LDC (tip) from bitbucket mercurial repo, ccmake, adjust paths to match those of MacPorts (/opt/local).

Then build and install tango, as described in the link above.

Edit ldc.conf


switches = [
"-I/opt/local/include/d",
"-I/opt/local/include/d/tango/core/vendor",
"-L-L%%ldcbinarypath%%/../lib",
"-L-ltango",
"-d-version=Tango",
"-defaultlib=tango-ldc",
"-debuglib=tango-ldc"
];
