<h2 id="introduction">Introduction</h2>
|
|
|
|
<p>Lua-iconv is POSIX 'iconv' binding for the Lua Programming Language. The
|
|
iconv library converts a sequence of characters from one codeset into a
|
|
sequence of corresponding characters in another codeset. The codesets
|
|
are those specified in the iconv.new() call that returned the conversion
|
|
descriptor, cd.
|
|
</p>
|
|
<p>Lua-iconv 7 *requires* Lua 5.1 or Lua 5.2. For Lua 5.0, use the first
|
|
release (lua-iconv-r1).
|
|
</p>
|
|
<p>Details on iconv may be obtained in the Open Group's interface definition
|
|
(<a href="http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.h.html">http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.h.html</a>).

|
</p>
|

|
<h2 id="download-and-installation">Download and installation</h2>
|
|
|
|
<p>Lua-iconv can be obtained from its GitHub project page
|
|
(<a href="https://github.com/ittner/lua-iconv/downloads">https://github.com/ittner/lua-iconv/downloads</a>), from a LuaRocks server or
|
|
from some Linux distributions which already provide it (eg. Debian).
|
|
</p>
|
|
<p>Unless you downloaded a compiled package, you must build the library for
|
|
your system. If you have LuaRocks installed, all the process is automatic;
|
|
just fire up your favourite shell and type, as root:
|
|
</p>
|
|
<pre> luarocks install lua-iconv
|
|
|
|
</pre><p>and the package will be downloaded from a rock server, installed and
|
|
configured. Otherwise, you must compile and install the package. In a system
|
|
with pkg-config (as many Linux distributions and Unix flavors) open a shell,
|
|
untar the distribution package and, within the program directory, type:
|
|
</p>
|
|
<pre> make install
|
|
|
|
</pre><p>as root. The library will be compiled and installed on the in the correct
|
|
path (which is defined in lua5.x.pc). Compiling on systems without pkg-config
|
|
requires manual changes in the Makefile (this includes Windows).
|
|
</p>
|
|
|
|
|
|
<h2 id="loading-and-initialization">Loading and initialization</h2>
|
|
|
|
<p>Lua-iconv is a shared library that must be loaded in the Lua interpreter
|
|
before use. You can simply do a
|
|
</p>
|
|
<pre> local iconv = require("iconv")
|
|
|
|
</pre><p>call to load up the library (that, of course, must be installed in a
|
|
directory from package.cpath).
|
|
</p>
|

|
<pre> cd = iconv.new(to, from)
|
|
cd = iconv.open(to, from)
|
|
|
|
Opens a new conversion descriptor, from the 'from' charset to the
|
|
'to' charset. Concatenating "//TRANSLIT" to the first argument will
|
|
enable character transliteration and concatenating "//IGNORE" to
|
|
the first argument will cause iconv to ignore any invalid characters
|
|
found in the input string.
|
|
|
|
This function returns a new converter or nil on error.
|
|
|
|
|
|
nstr, err = cd:iconv(str)
|
|
|
|
Converts the 'str' string to the desired charset. This method always
|
|
returns two arguments: the converted string and an error code, which
|
|
may have any of the following values:
|
|
|
|
nil
|
|
No error. Conversion was successful.
|
|
|
|
iconv.ERROR_NO_MEMORY
|
|
Failed to allocate enough memory in the conversion process.
|
|
|
|
iconv.ERROR_INVALID
|
|
An invalid character was found in the input sequence.
|
|
|
|
iconv.ERROR_INCOMPLETE
|
|
An incomplete character was found in the input sequence.
|
|
|
|
iconv.ERROR_FINALIZED
|
|
Trying to use an already-finalized converter. This usually means
|
|
that the user was tweaking the garbage collector private methods.
|
|
|
|
iconv.ERROR_UNKNOWN
|
|
There was an unknown error.
