Vs2013在Linux开发中的应用（26）：表达式计算

当VS调试时将鼠标移到一个变量上面的时候，VS将显示这个变量的值，实际上这个时候VS进行了表达式的计算，我们所需要做的，就是把这个过程转换为gdb的命令：

Operation	Description
-enable-pretty-printing	enable Python-based pretty-printing
-var-create	create a variable object
-var-delete	delete the variable object and/or its children
-var-set-format	set the display format of this variable
-var-show-format	show the display format of this variable
-var-info-num-children	tells how many children this object has
-var-list-children	return a list of the object’s children
-var-info-type	show the type of this variable object
-var-info-expression	print parent-relative expression that this variable object represents
-var-info-path-expression	print full expression that this variable object
	represents
-var-show-attributes	is this variable editable? does it exist here?
-var-evaluate-expression	get the value of this variable
-var-assign	set the value of this variable
-var-update	update the variable and its children
-var-set-frozen	set frozeness attribute
-var-set-update-range	set range of children to display on update

经过转换，我们就可以在VS的窗口中看到表达式计算的结果了：
