Nvwa is my small collection of C++ utilities in Open Source. It includes a memory leakage detector, a ‘static’ memory pool, a thread transparency layer, and other such stuff. Release 1.0 can be downloaded here. The latest README is here.
Libunibreak is an open-source implementation of the line and word breaking algorithms as described in Unicode Standard Annexes 14 and 29. Line and word splitting is much more than breaking at the spaces (the China Web world often sucks at this)!
I am not a serious writer or translator, but I was honoured to be one of the three translators to translate a very good old book, Programmers At Work. You can find out more details (in Chinese) in the link of the Chinese translation.

gvim74.zipupdated: my personal Win32 build of gvim.exe and
vim.exe version 7.4.2098 (DirectX support introduced in 7.4.393 is
compiled in the GUI version so as to support Unicode characters beyond BMP).
It differs from the standard Vim
executables in the following ways: 1) the file and product versions
are in the form major.minor.patchlevel (not
major.minor.build.patchlevel) and are
consistently updated; 2) both the GUI and console versions are
compiled with Perl, Python2, Python3, Ruby, Tcl, and Lua support; 3) Ruby
2.0 is used (instead of Ruby 1.9.2); and 4) a private patch is used to
make plug-ins like fencview.vim
run more smoothly on Windows.
The build and patch files can be
downloaded as an archive.
Check out my GitHub Vim page on
how I build Vim.
breaktext: a small program that uses libunibreak (formerly
liblinebreak) to break the lines of input text. Type
breaktext’ for the usage. Some usage examples
breaktext input.txt output.txt’ breaks a
UTF-16 text file with no explicit language info; ‘
’ breaks a Chinese text file encoded in CP936. The
source has only changed slightly recently, but I have to build the Windows
binary with MSVC now, as MinGW GCC (which I used back in 2009) uses the
unreliable C runtime — MSVCRT.DLL — which is terribly
broken in Windows versions later than Windows XP when dealing with
multi-byte characters, without even being able to output a single Chinese
putwchar(wch)! The same code runs without any
problems in MSVC versions that do not depend on MSVCRT.DLL (i.e., any MSVC
compilers later than Visual C++ 6.0).
jhead-3.00-ccdwidth_hack.zip: a modified version of the command-line tool jhead that reports the correct ‘35mm equivalent focal length’ on resized photos from Canon digital cameras (this is a common problem for resized digital photos, if they do not contain the EXIF 2.2 tag ‘FocalLengthIn35mmFilm’ — Picasa has this problem too). This download contains the original jhead 3.00 source, my patch, and prebuilt binaries for Mac OS X Snow Leopard and Microsoft Windows.
or as HTML: my Vim
configuration file for Windows. It is 23 KB, and is designed for Vim 7, with
heavy customizations on using Chinese/Japanese/Korean
together with Western European languages. It is well commented, and
should serve as a good reference if you intend to customize your Vim.
Notice: You should have iconv to set a different
encoding, as is done in this
_vimrc. Please download libiconv-win32
and extract iconv.dll to somewhere in the path or where gvim.exe
is, if you do not have it already. After doing that, you should also save the
original libintl.dll in the Vim directory, and replace it with
intl.dll from gettext-win32
tellencupdated: a program to detect the encoding of a text file (source and Win32 binary included). It supports ASCII, UTF-8, UTF-16, UCS-4, Latin1, Windows-1252, CP437, GB2312, GBK, Big5, SJIS, etc. It is intended to work with Vim for file encoding autodetection: first multienc.vim, and now fencview.vim. The latest source is available on GitHub, but the Windows binary will be provided here from time to time.
A Vim plug-in to echo the function declaration as in the tags file. It
display the function declaration when ‘
(’ is typed,
and it support displaying the function declaration, variable definition, etc.
as tooltips when Vim is compiled with
the CVS integration plug-in for Vim.
I use it daily, so it is updated quite often. It supports
menu and short-cut operations, and has special multi-encoding support. The
script is now hosted at Vim Online (don’t forget to give me a good rating
if you find it useful ;-)). You can see some snapshots here: CVS Annotate, CVS Diff, CVS Log, CVS Directory Local
status; and an old snapshot showing the menu.
my personal Win32 build of gvim.exe version 6.4.10 (with no Perl,
Python, Ruby, or Tcl support) with a special patch. This is for archival
purpose only, since Vim 7 has already incorporated the patch, as well as added
many new features. The patch is necessary for the Vim option
encoding=utf-8 to work reliably on Far East versions of Windows,
*printf functions in the Microsoft C Runtime
(MSVCRT.DLL) require the format string to be encoded as expected by the
country preference specified in the Regional Options if one calls
setlocale(LC_ALL, ""). It works very well for me, but Bram did
not accept in into the 6.x source tree because he thought the patch was
a little risky
for a stable version. See also my old _vimrc.
