kandi X-RAY | mysh Summary

mysh is a C library typically used in Utilities, Parser applications. mysh has no bugs, it has no vulnerabilities and it has low support. However mysh has a Non-SPDX License. You can download it from GitHub.

Now I wont dive into deeper into every aspects of the shell code. I'll just highlight the main concepts. We start at the entry point of the program. Since I am programming this for *nix system, we would have to get or redirect the unix signals like Ctrl-Z, Ctrl-C and Ctrl-\. Then there is a main loop which would frequently scan for commands, parse it into token, check the grammar and syntax and either produce an error or an output the resulting command. Until now, we have scanned the user input, have broken them down into array of lexis or tokens and now we try and run them through a parser which parses them into an Abstract Syntax Tree. If there is an error in the user grammar, the parse will throw out an error.

Searching for a string of text from the main body and footnotes and copying it and its following # characters into an excel document

Asked 2022-Mar-30 at 12:26

I have a large number of documents which I need to pull out file name references from, spread out across large blocks of text and footnotes.

I currently have a word VBA code that I think should search for a string (for example "This_") and then the following # of characters, and then paste them into a waiting excel sheet. I am struggling to get it to search both the footnotes and the main body of text.

I've been using the code below, but my work at the moment is making it do something weird. It will find the string I am searching for, but then it will copy from the start of the document the number of times the string has been found -- not the string and its subsequent text.

Any help would be appreciated in modifying this, I believe the issue will be coming from the first half of the 'return data to array section.

Where is my memory leak not being freed in this shell simulation?

Asked 2021-Oct-29 at 23:11

I can't find where my memory leak isn't being freed in a shell simulation C program using the valgrind tool. I also ran my program using the gdb debugger. writableUsersArgs contained "/usr/bin/vim" as the first element and NULL as the second element. Using the debugger, it showed the array writableUsersArgs was freed twice.

In start you allocate memory with malloc and assign it to a pointer, then you overwrite the content of the pointer with NULL. You have now lost track of the malloced memory.

QUESTION

Excel Addin not executing Call Function

Asked 2021-Oct-03 at 16:55

I have a sharepoint site which I use vba to upload new data. I have created a Excel Addin which we will deploy to other users so that anybody can upload.

The Excel Addin consists of two modules. The first module is the "functions" module and the second is the code which runs when the button is pushed on the Addin. If I test all this with a normal Excel Macro workbook, it works perfect. However when I test it in the Addin feature, the "Call SaveChanges" part does not work.

Does anybody have any idea what is causing this part to not work? I have even tried adding another button on the Addin for the SaveChanges part but still not working as a Addin.

The SaveChanges Sub it is calling is what saves the data back to sharepoint.

If you use the code as an Add-In, you need to specify that you no longer want to save something in a sheet of the Add-In itself, but rather a sheet of the ActiveWorkbook.

So you need to add a couple of lines:

You can first check if the contains + button using InStr function, if so then click the + button. After clicking all the + button in the table, you can read the data and write them into the sheet.

The working example is like this:

The subclass relation Show a => Test a (read: Show is a superclass of Test) simply means that any type which is an instance of Test must also be an instance of Show, i.e. pretty much exactly what GHC is telling you. To this end, well, write that instance:
