Tclunqlite v0.1

我實作了 UnQLite 一部份的 Database Engine Handle, Key/Value Store Interfaces, Cursor Iterator Interfaces 與 Manual Transaction Manager 功能。

UnQLite 的儲存方式有二種，一種是 key-pair，一種是 JSON 文件。目前我已經實作了一部份 key-pair 方式的功能。

這是一個嘗試實作的 draft 版本，我有寫一些簡單的測試檔案進行測試目前實作的部份，不過因為沒有大量測試，所以請不要用在需要高可靠度的環境。

Tclunqlite

About

This is the UnQLite extension for Tcl using the Tcl Extension Architecture (TEA).

UnQLite is a in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine. This extension provides an easy to use interface for accessing UnQLite database files from Tcl.

License and version

BSD license, v0.1 (draft version)

UNIX BUILD

Building under most UNIX systems is easy, just run the configure script and then run make. For more information about the build process, see the tcl/unix/README file in the Tcl src dist. The following minimal example will install the extension in the /opt/tcl directory.

$ cd tclunqlite
$ ./configure --prefix=/opt/tcl
$ make
$ make install

WINDOWS BUILD

The recommended method to build extensions under windows is to use the Msys + Mingw build process. This provides a Unix-style build while generating native Windows binaries. Using the Msys + Mingw build tools means that you can use the same configure script as per the Unix build to create a Makefile.
