如何调试 Expect_before 行为
我对 TCL/expect 比较陌生，主要修改现有代码。expect_before 似乎没有达到我的预期（这很好），但我不知道如何调试它。 我已经使用了 -d 选项，现在用于
exp_internal -f "argh.log" 1
创建日志文件，但它对我没有帮助。
expect_before -info
似乎很有用，但我无法抓取/显示输出（我确实说过我是 TCL 的新手）
I am relatively new to TCL / expect and mostly modifying existing code.expect_before doesn't seem to do what I expect (which is fine) but I can't work out how to debug it.
I have used -d option and am now using
exp_internal -f "argh.log" 1
to create a log file, but it isn't helping me.
expect_before -info
seems useful, but I am not able to grab / display the output (I did say I was new to TCL)

函数结果可以通过使用
set来获取当前配置。
使用exp_internal对于查看表达式的计算方式也很有用，一旦您理解了输出 - 当您的expect_before尚未按预期设置时，它应该是显而易见的。
Function results can be grabbed in expect by the use of
setwill grab the current configuration.
Using
exp_internalis also useful to see how expressions are evaluated, and once you understand the output - it should be obvious when your expect_before has not been set up as expected.
