Mozi is my new collection of C++ experimental utilities in Open Source. It currently includes code for C++17-based static reflection.
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)!
Nvwa is my small collection of C++ utilities. It includes a memory leakage detector, a ‘static’ memory pool, a thread transparency layer, and other such stuff.
I have a C++ course and a Vim course on 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。如果你对这些内容有兴趣的话，也许可以去看一下。
I was part of a team that translated Bjarne Stroustrup’s HOPL4 paper: ‘Thriving in a Crowded and Changing World: C++ 2006–2020’. Highly recommended for all C++ users.
我参与了一项团队工作，协助翻译了 Bjarne Stroustrup 的 HOPL4 论文： 《在纷繁多变的世界里茁壮成长：C++ 2006–2020》 。向所有 C++ 用户大力推荐。
In 2022, a few C++ advocates and I translated Rainer Grimm’s C++ Core Guidelines Explained into Chinese. This Chinese version is finally available now.
我和一些 C++ 爱好者在 2022 年翻译了赖纳·格林的《C++ Core Guidelines 解析》 。目前该中文版已经出版。
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.
我很荣幸地参加了《编程大师访谈录》的翻译工作。这本书有点年头了，但今天看仍很有意义。

gvim91.zipupdated: my personal Win32 build of gvim.exe and vim.exe version 9.1.0924. 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 or MzScheme); 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 to break
the lines of input text. Type ‘breaktext’ for the
usage. Some usage examples (Windows): ‘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 and statically linked, so as to
enhance compatibility and avoid the broken behaviour of multi-byte characters
in MSVCRT.DLL later than Windows XP. See articles
about Microsoft Unicode I/O bugs above.
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.
_vimrc
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 fileencoding from
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
(with renaming).
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.
echofunc.vim:
A Vim plug-in to echo the function declaration as in the tags file. It
displays the function declaration when ‘(’ is typed,
and it supports displaying the function declaration, variable definition, etc.
as tooltips when Vim is compiled with +balloon_eval.
gvim82.zip: my personal Win32 build of gvim.exe and vim.exe version 8.2.5172. 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.
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.
gvim64_patched.zip:
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 this patch. The patch is
necessary for the Vim option encoding=utf-8 to work reliably on
Far East versions of Windows, since the *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.
cvsmenu.vim: the CVS integration plug-in for Vim. It supports menu and short-cut operations, and has special multi-encoding support. You can see some snapshots here: CVS Annotate, CVS Diff, CVS Log, CVS Directory Local status; and an old snapshot showing the menu.
reimp (enhanced version by José Fonseca): a tool to convert a Win32 import library (.lib) into a .a file usable with GCC for Win32 (MinGW).
CGIC 1.07 (fixed for Win32): CGI programming library in C by Thomas Boutell.

GCC: the prosperity of Open Source software depends upon this Open Source C/C++/Fortran/Java/… compiler
WinLibs build: free C and C++ compiler for Microsoft Windows (the versions that use the UCRT runtime are better suited for modern Windows, since the MSVCRT runtime is pretty old and can cause surprising woes—as with some other GCC builds)

Cygwin: a Linux-like environment for Windows
Windows binaries of GNU Wget: the non-interactive GNU downloader. I used to use binaries from Bart Puype’s WGET for Windows page, which featured very small executables.

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.
