Missing built-in command “history” for Tcl C extension

Question

I am working on a project need Tclsh like support with some self-defined commands. I implemented following code (based on Tcl 8.5):

Tcl_Main(argc, argv, Tcl_AppInit);

And put new commands registration in Tcl_AppInit. Everything looks fine, except that with the new command line interpreter, when I type Tcl built-in command "history", I got :

% history
invalid command name "history"

Other built-in commands work fine, like "puts", "set", etc. Why ? Do I have to implement my own "history" command instead?

在这里添加我的解决方案：事实证明， history是Tcl脚本库的一部分，需要在初始化期间通过提供$TCL_LIBRARY/init.tcl或调用Tcl_Init(interp) 。
