How do Ruby and Python implement their interactive consoles?

由 只谈情不闲聊 提交于 2019-12-09 16:39:42
问题 When implementing the interpreter for my programming language I first thought of a simple console window which allows the user to enter some code which is then executed as a standalone program as a shell. But there are severe problems: If every line of code the user enters is handled as a standalone program, it has to go through the tokenizer and parser and is then just executed by the interpreter - what about functions then? How can the Python/Ruby interactive consoles (IDLE, irb) "share"

Regex to validate SMTP Responses

由 佐手、 提交于 2019-12-08 17:01:23
I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with( out ) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to

Getting output from os.system (no subprocess)

由 与世无争的帅哥 提交于 2019-12-08 13:42:07
问题 I am trying to capture and/or remove the output of a command launched by a os.system() call. The script will run under Linux and Windows. I cannot use the subprocess module because the said command is interactive (i.e. : the user can type instructions to trigger various actions). So please do not mention this thread as a duplicate of the common questions asked for instance in : Python: How to get stdout after running os.system? How to store the return value of os.system that it has printed to

问题 I have created a EFI Pre-Boot Application were in I enter the user credentials which are passed to windows to logon (Single Sign On) using my credential provider. I have a Group policy "Interactive logon: Smart card removal behavior" set to "Lock Workstation: The workstation is locked when the smart card is removed, allowing users to leave the area, take their smart card with them, and still maintain a protected session." So if I reboot the machine and use login using my credential provider,

Using bokeh to plot interactive pie chart in Jupyter/Python

由 巧了我就是萌 提交于 2019-12-08 06:44:39
问题 I am new to Bokeh and I would really appreciate some help in figuring out how to use Bokeh to plot a simple interactive pie chart in Jupyer/Python. I am planning to use 'CustomJS with a Python function' in Bokeh as explained at the bottom of the page here. The pie chart consists of two entries with a slider that can change the shape of one pie 'v2' inside the circle shape of (v1+v2). I have tried to follow the example in bokeh website that shows the interactivity with a sine plot, but I just

git bash shell on Windows “Your edited hunk does not apply”

由 六月ゝ 毕业季﹏ 提交于 2019-12-08 04:13:45
问题 I have a very frustrating error when trying to manually edit hunks while using the command: git add -p I have already looked through many of the existing questions on this site, including this one, and this one. I am at the point where I try to manually edit a hunk, make no changes to the file opened by git for manual editing, and still getting the error "Your edited hunk does not apply". I thought this might have to do with CRLF vs. LF EOL characters. I am editing in Notepad++, and I can see

问题 As the topic implies I am looking for a way to combine interactive shiny plots with knitr´s way of producing presentations/pdfs.
