Examples_Cocoa VS Platypus

Here is a minimal Hello World Objective C program. You'll need to figure out how declare the needed Objective C interfaces and how to call them from Rust. The C ABI function objc_msgSend will get you part of the way there.

So, the problem I run into is finding resources for learning the GNUstep api. Not to criticize, but when I search many of the links I click on are dead, and when I do find a live one, it seldom gives me much more than a list of methods. I finally found this repo (https://github.com/gammasoft71/Examples_Cocoa) which has given me a lot of help.

Something for which I wish there was a windows variant...

Embedding a script into a small tray icon/menubar app can be extremely powerfull even with its low complexity.

neovim, mutt, tig, weechat

Unfortunately, it's not that simple on macOS for app bundles. The human readable name of the app bundle really doesn't matter that much to the operating system -- it's the contents of Info.plist that matter. In order to have a separate app that can be Cmd+Tab'd to, you have to have a separate app bundle, separate app bundle identifier, etc. There's really not a way around it on macOS that I've seen.

(And to be clear, aliases do work on the command line. I'm talking specifically about GUI apps - which is my primary method of separating my different activities. Terminal emulator tabs are not good enough.)

This also doesn't solve the performance problems with any of the various GUI applications, nor does it solve my problem for other applications that I want to run.

I do! I tried this route first, but it falls apart when you start a GUI application from the script that you supply to platypus. If your script is e.g. `wezterm start`, it'll just start up another instance of a wezterm-branded GUI app in addition to the wrapper app that Platypus spits out.

Random fact; this website is created and maintained by Sveinbjörn Þórðarson who also made Platypus (https://github.com/sveinbjornt/Platypus) and Sloth (https://github.com/sveinbjornt/Sloth) — software that Mac nerds might be familiar with.

Sveinbjörn is a ball of energy that just radiates positives for human society.

Not sure if I understood the question properly but I found this program for Macs the other day: Platypus. It will create a .app out of any scrap of code.
