Vim script that I used to flip YARDoc from Java style to Ruby style

flip_flop_yard_doc.vim

" Fix YARD documentation comments in one file.

Me

In YARDoc documentation, I've noticed that usually we use the @param tag as @param variable_name [VariableType] some plain English description. However, in some parts of the documentation, I see that the variable name and variable type are switched, i.e. @param [VariableType] variable_name some plain English description. Is this intentional? Are both formats allowed? Is there some debate on this? Which format is more popular?

GPT

In YARDoc documentation, both formats for the @param tag are allowed and considered valid. The format @param variable_name [VariableType] some plain English description is called the "Ruby Style" and is the default format used by YARDoc. The format @param [VariableType] variable_name some plain English description is called the "Java Style" and is also supported by YARDoc.

There is some debate on which format is better, but ultimately it comes down to personal preference and the conventions of the codebase being documented. Some developers prefer the Ruby Style because it follows the natural order of the parameter declaration in Ruby, while others prefer the Java Style because it puts the type information up front and can be easier to read.

In general, the Ruby Style is more popular in the Ruby community and is the default format used by YARDoc, so you'll see it more often. However, both formats are valid and supported by YARDoc, so you should choose the one that works best for you and your project.

• You are Tim Pope, a world-renowned expert in the use of Vim, the highly configurable text editor that is beloved by programmers and power users alike. As a Vim expert, you have spent countless hours honing your skills and developing plugins that help users be more productive. Today, you are here to share your knowledge and expertise with the world.
• I am an experienced vim user and software engineer working on a rails 6.1 ruby 2.7 application.
• The application uses YARD documentation comments, but there's a mistake in how we've been doing it.
• Rather than documenting the parameter with @param variable_name [VariableType], we've been documenting it with @param [VariableType] variable_name.
• I've written a vim script that will fix the documentation comments. I've defined a function to fix one file at a time, and to fix all files at once.
• When I run my function to fix one file at a time, it works as expected.
• But when I run my function to fix all files at once, the function to fix just one file crashes with the following output.

  Error detected while processing function FixAllYardComments:
  line    5:
  E730: using List as a String
  [`rg --files-with-matches]
  "`rg --files-with-matches" [New File] --No lines in buffer--
  Error detected while processing function FixAllYardComments[8]..FixYardComments:
  line    8:
  E486: Pattern not found: @param \[\(.*\)] \(\w\+\)
  

• So tell me, Tim, how should I update the vim script below so as to fix this problem? Please respond with an updated version of the vim script, but also please explain what is the reasoning behind the change, and an explanation of any vim features that you employ.

Below will follow the vim script.
