Change save path of PHP interactive shell history

阅读更多关于 Change save path of PHP interactive shell history

问题 I once found a way to disable session logging by php -a , php's interactive shell. How do I turn it back on? Is there a way to send logging to another, file besides ~/.php_history ? I think I may have sent the output to /dev/null . edit: It apparently still saves to the .php_history file. It doesn't save until you exit completely from the shell. I would still like to know how move the history logging to another file. 回答1: No, currently (5.3.10 ubuntu) the filename ~/.php_history is hardcoded

Custom Interactive Shell with AutoComplete

阅读更多关于 Custom Interactive Shell with AutoComplete

问题 I have been tasked to create an interactive shell to be embedded in python, such that, when called from the command line it will be dropped into that shell. Can anyone recommend me a library that does this?

IPython behavior different for .py and .ipy files despite script being “pure” python (custom exception handler hook stops working)

阅读更多关于 IPython behavior different for .py and .ipy files despite script being “pure” python (custom exception handler hook stops working)

问题 I have written an exception handler that is meant to log all uncaught exceptions in the code before calling the normal python exception hooks. Python and iPython have slightly different ways of doing this. What i have found is that the iPython way of doing it only works when run from within an interactive session, or when using a ".ipy" filename extension, despite the fact that I don't believe i am using any 'Magic,' and the regular python way of doing it won't work within ipython even if the
