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.
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 Chinese Web world often sucks at this)!
I have written a C++ column and a Vim column for Geek Time. If you happened to be interested in these topics (and know Chinese), you might want to take a look.
我为极客时间写了一个 C++ 专栏和一个 Vim 专栏。如果你对这些课题有兴趣的话，也许可以去看一下。
I am not a serious writer or translator, but I was honoured to be one of the three translators of a very good old book, Programmers At Work. You can find out more details (in Chinese) in the link of the Chinese translation.

gvim82.zipupdated: my personal Win32 build of gvim.exe and vim.exe version 8.2.2811. 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, and Ruby support (but no Lua, MzScheme, or Tcl); 3) a private patch is used to make plug-ins like fencview.vim run more smoothly on Windows. 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;
breaktext ’ breaks a Chinese text file
encoded in CP936. The source code is now hosted on GitHub, and a
Windows binary is provided in this download. It has been built with MSVC, 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 character by
putwchar(wch)! The same code runs without any problems when the
C runtime is statically linked with MSVC (or
dynamically linked when the MSVC version is
between 2002 and 2013 inclusive; see articles about Microsoft Unicode I/O bugs
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’. This download contains the original jhead 3.00 source, my patch, and prebuilt binaries for Mac OS X (Snow Leopard and later) 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
for Vim 7 users: You need to have iconv (automatically
installed by Vim 8) 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
tellenc: 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
displays the function declaration when ‘
typed, and it supports displaying the function declaration, variable
definition, etc. as tooltips when Vim is compiled with
gvim74.zip: my personal Win32 build of gvim.exe and vim.exe version 7.4.2367 (DirectX support introduced in 7.4.393 is compiled in the GUI version so as to support Unicode characters beyond the 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.
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

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.

I am Chinese, and my full name in Chinese is 吴咏炜 (Wu Yongwei). Eastern names usually go with family name first, so my given name is ‘Yongwei’. I have been a programmer for more than 30 years, and am mostly interested in writing code that is reliable, reusable, efficient, and cross-platform. You can check out my GitHub repositories for my open-source contributions.
