            What is the best practice of passing reference counted C++ objects to Lua?
            Asked 2021-Jun-16 at 02:17

            I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

            Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

            Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

            In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.

            I assume you have implemented two Lua functions in C: inc_ref_count(obj) and dec_ref_count(obj)

            How to remove VIM as my Mac editor vs sublime
            Asked 2021-Jun-15 at 06:57

            How to remove VIM (completely) and change my mac command line editor to sublime?

            I've spent the last three hours reading the same links on "how to remove VIM" only to get "how to remove MacVIM and reinstall it fresh" Or "How to remove Vim so I can reinstall it on Ubuntu"

            My old laptop was fortunate to have a friend remove it but my new machine still has it installed.

            I wish VIM would die in "words redacted to excessive profanity" dumpster fire while a hobo "words redacted to excessive profanity" to put out the fire

            I've lost way too many hours trying to learn that outdated neckbeard elvish piece of UX trash so I want it gone. No, I'm not touching emacs.

            Please tell me there is a way I can switch to sublime or am I permanently cursed to have this confusing black screen of death pop up when I try to git push or git tag stuff?

            My original goal was to tag a git and push it but vim comes up and I can't figure out how to speak elvish.

            I've been using PyCharm for a few years and love the interface but I need to dig deeper and a TDD Django book for class uses the terminal, it wants me to git -a "comments" so I need your advice.

            So now I can't learn TDD Django because vim, MacVim and eMacs users flood the internet but I can't remove it nor figure out how to work it.

            I've tried brew uninstall macvim which doesn't work because I have vim not macvim

            I also tried sudo uninstall vim no luck as this is zsh mac not ubuntu

            I tried brew uninstall vim to get No available formula or cask with the name "vim"

            I've searched SO five times and keep getting the same links. Alternates I've tried brew uninstall ruby vim

            per this post https://superuser.com/questions/1096438/brew-upgrade-broke-vim-on-os-x-dyld-library-not-loaded I tried, no luck.

            You don't have to remove Vim from your machine. Instead, tell your system and your tools to use Sublime Text as default editor. After you have followed that tutorial, which I must point out is part of Sublime Text's documentation, you should have a system-wide subl command that you can use instead of vim. For that, you need to add those lines to your shell configuration file:

            Extract n words after a pattern word
            Asked 2021-Jun-14 at 19:00

            This is my first time attempting to extract a string using gsub and regular expressions in R. I would like to extract three words after the first occurrence of the word "at" or "around" in each cell of a text column (col in example) and place the extraction into a new column (new_extract).

            Answered 2021-Jun-14 at 19:00

            Your regex attempts to match words only after the last at. Also, since there is no pattern to match the gap between at or around (you are not trying to match around at all by the way), your pattern will not extract any words in the end.

            I suggest this approach with sub:

            You've made a mess of things by incorrectly installing the module. Specifically, you didn't install the dependencies.

            Ideally, you should use the package manager that provided perl itself. But they don't provide every module. So you'd use the non-package manager approach:

            finding a file in directory using perl script
            Asked 2021-Jun-14 at 09:41

            I'm trying to develop a perl script that looks through all of the user's directories for a particular file name without the user having to specify the entire pathname to the file.

            For example, let's say the file of interest was data.list. It's located in /home/path/directory/project/userabc/data.list. At the command line, normally the user would have to specify the pathname to the file like in order to access it, like so:

            cd /home/path/directory/project/userabc/data.list

            Instead, I want the user just to have to enter script.pl ABC in the command line, then the Perl script will automatically run and retrieve the information in the data.list. which in my case, is count the number of lines and upload it using curl. the rest is done, just the part where it can automatically locate the file
