scripting

问题 I use dynamic script loading to reduce the duration of the initial page load. To ensure that the functions and objects defined by a script are accessible, I need to ensure that the script has been fully loaded. I have developed my own Javascript library to this end, and thus did quite a lot of research on the subject, studying how it's done in different libraries. During a discussion related to this issue, Kyle Simpson, the author of LABjs, stated that: LABjs (and many other loaders) set both

问题 I have a class describing a Point (has 2 coordinates x and y) and a class describing a Polygon which has a list of Points which correspond to corners (self.corners) I need to check if a Point is in a Polygon Here is the function that is supposed to check if the Point in in the Polygon. I am using the Ray Casting Method def in_me(self, point): result = False n = len(self.corners) p1x = int(self.corners[0].x) p1y = int(self.corners[0].y) for i in range(n+1): p2x = int(self.corners[i % n].x) p2y

问题 The typical header should be #!/usr/bin/env python But I found below also works when executing the script like $python ./my_script.py #!/usr/bin/python #!python What's difference between these 2 headers? What could be the problem for 2nd one? Please also discussing the case for python interpreter is in PATH or not. Thanks. 回答1: First, any time you run a script using the interpreter explicitly, as in $ python ./my_script.py $ ksh ~/bin/redouble.sh $ lua5.1 /usr/local/bin/osbf3 the #! line is

问题 I want to monitor a drive for file changes, using VBScript. I have the below code. It works fine for InstanceCreationEvent and InstanceDeletionEvent . But InstanceModificationEvent is not happening. From googling I got to know we need to use CIM_DataFile instead of CIM_DirectoryContainsFile to monitor InstanceModificationEvent . I am not sure how to modify the code. Can anyone help. FYI: One script should monitor all the folders and subfolders in a drive. PS: Any suggestion to improve the

问题 I would like to write WinSCP script to download a file that is placed onto the remote server every morning between 4-4:30am. Is there a way to do this with time-stamping? I want to pseudocode: get file.txt where timestap<1 hour from 4 am 回答1: First, I assume your file does not have fixed name (contrary to your question with fixed name file.txt ). If not, please explain, why do you need timestamp-based solution. Anyway, you can use a file mask with a time constraint: get "*.txt>2014-07-19 4:00

问题 I was trying to process a text file in a Windows batch script and I ran into something that looks like a limitation to 31 tokens in a FOR loop. I isolated the issue in the code below: @ECHO OFF SET DATA=01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 FOR /F "tokens=31* delims= " %%i IN ("%DATA%") DO ( ECHO [%%i] ECHO [%%j] ) ECHO. FOR /F "tokens=32* delims= " %%i IN ("%DATA%") DO ( ECHO [%%i] ECHO [%%j] ) The output is: [31] [32 33 34

问题 I have a few script that had their own copy of a some functions, so I extracted these functions to a module and had the scripts import the function. These script are to be copied over to a bunch of linux servers and executed. When the scripts worked standalone, I would simply copy the files over to the servers and execute "python ". I have a central management server that will copy and run the scripts on the different servers. I've done some reading on python eggs, but could use some advice

问题 I'm experimenting with a Windows batch file to perform a simple operation which requires the user to enter a non-negative integer. I'm using simple batch-file techniques to get user input: @ECHO OFF SET /P UserInput=Please Enter a Number: The user can enter any text they want here, so I would like to add some routine to make sure what the user entered was a valid number. That is... they entered at least one character, and every character is a number from 0 to 9. I'd like something I can feed
