lua: module import regarding local scope

由 夙愿已清 提交于 2019-12-12 10:53:45
问题 There are two script files with the following script //parent.lua function scope() local var = "abc" require "child" end //child.lua print(var) This way, child.lua will print a nil value because the scope in parent.lua does not expose its local features to the module. I thought it would, since the require directive is stated within this scope and after the declaration of var. My desire is to practically wholly inject all the lines of the child into the parent. The child script is just

Pointers and memory scope

问题 I have been programming C for a while (but still pretty new to C) and I am sometimes getting confused of the way the C is handling the memory. Consider following valid C snippet: const char *string(void) { /* where is this pointer variable located in the memory? */ const char *s; /* where is this text data located in the memory? */ /* and when the program allocates memory for it? */ s = "Hello, World"; return s; } int main(void) { printf( "%s", string() ); return 0; } I am asking what exactly

Unbound Local error in Python I can't shake!

问题 http://pastie.org/1966237 I keep getting an unbound local error. I don't understand why it occurs, if the program is running right, it should go straight into the second assignment of the print_et_list function within the main function, looping itself without actually looping. The program only quits using sys.exit() in the hey_user function. I included the whole program for context, it isn't too long. Let me know if you want to have a look at the text files I use in the program, however I'm

问题 I have to check if a driver is installed on a virtual machine. I need to output a drivers list using Powershell (msinfo32.exe -> Software Components, System Drivers). The (impersonated) user account I want to check is "test". When I run my command locally with "test" using Remote Desktop, it works fine, I get all drivers : PS C:\Users\test> Get-WmiObject win32_systemdriver So I can check if the concerned driver is running : PS C:\Users\test> Get-WmiObject win32_systemdriver | Where-Object{$_

crossrider: store snapshot of bookmarks in local database and compare to current bookmarks list

由 不打扰是莪最后的温柔 提交于 2019-12-12 05:21:40
问题 How do I store a snapshot of the bookmarks list and then compare that to the current bookmars list every n amount of time with a conditional statement that outputs any bookmarks that have been added? I have been trying to do this to no avail. It would be great if you could provide a code example but if you just want to explain it conceptually it would be fine. 回答1: Conceptually, you can achieve your goal by storing the previous bookmarks list in the extension's local database using appAPI.db

How can I recover those files (birng everything back before that git checkout -- smdr comand)? 回答1: You can't with Git. The files were not committed so they are not in history.

How to make “local” the label in a 8086 procedure?

由 时光怂恿深爱的人放手 提交于 2019-12-12 03:36:42
问题 The problem is that some (many) labels have the same name, in particular: there are many procedures and each works properly if run "isolated" from the others. In fact, the labels used in different procedures have all the same common names such as "skip", "cycle", and so on. I know that in the macros could be used the directive LOCAL <label1>, <label2>, ... . But this directive doesn't work into a procedure. Changing each label is very boring, but not impossible to do, the real problem is that
