Go language tutorial manual

Course Elementary 27455

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.

Add line breaks after two conditions are met: no more than "x" characters and ending with a comma or period

I'm working on a small project. The goal of this project is to strip the formatting (double spaces, numbers, and newlines) and then output the value with a line wrap every "x" characters, but make sure it ends with a comma or period. For example...if I set the character limit to 50 (after the "l" in "until"), I want it to look like this. Note that this example favors punctuation over character limits, but it does not add line breaks unless you are at least close to the character limit (I added the extra commas to explain further): "The agile brown fox jumped over the lazy dog until the dog falls asleep

When I copy-paste content from a PDF, my screen freezes. So I think there is something wrong with my joi schema. description1:Joi.string().regex(/^(([\

Make a WordPress plugin work after a specific event (e.g. when a draft post is created)

I created a WordPress plugin (with the help of ChatGPT) that rewrites post titles in drafts to meet my required criteria of being between 36 and 38 characters long. Currently this is achieved by clicking the Autofill button, then letting ChatGPT rewrite the current draft title, then checking the reply to see its length, and if it does not meet the 36-38 character limit, the process is repeated until complete. Then change the title and publish the post. This works fine, however, I'm trying to make it more automated so I don't have to log into WordPress and simply
