schneems a50df1ab0e Setup SyntaxSuggest as default gem Adds the `syntax_suggest` syntax error display tool to Ruby through the same mechanism as `error_highlight` and `did_you_mean`. Reference ticket: https://bugs.ruby-lang.org/issues/18159 close #4845 ## What is syntax_suggest? When a syntax error is raised by requiring a file, dead_end will use a combination of indentation and lexing to identify the problem. > Note: Previously this tool was named `dead_end`. ## Known issues - SyntaxSearch's approach of showing syntax errors only works through integration with `require`, `load`, `autoload`, and `require_relative` (since it monkeypatches them to detect syntax errors). It does not work with direct Ruby file invocations https://github.com/zombocom/dead_end/issues/31. - This causes failure in the test suite (test_expected_backtrace_location_when_inheriting_from_basic_object_and_including_kernel) and confusion when inspecting backtraces if there's a different error when trying to require a file such as measuring memory (https://github.com/zombocom/syntax_suggest/issues/124#issuecomment-1006705016). - Discussed fix. We previously talked about opening up `SyntaxError` to be monkeypatched in the same way that other gems hook into `NoMethodError`. This is currently not possible and requires development work. When we last talked about it at RubyKaigi Nobu expressed an ability to make such a change.		2022-08-19 10:02:24 +09:00

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

Simple Syntax
Normal Object-oriented Features (e.g. class, method calls)
Advanced Object-oriented Features (e.g. mix-in, singleton-method)
Operator Overloading
Exception Handling
Iterators and Closures
Garbage Collection
Dynamic Loading of Object Files (on some architectures)
Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/maintainers.rdoc#label-Platform+Maintainers

How to get Ruby with Git

For a complete list of ways to install Ruby, including using third-party tools like rvm, see:

https://www.ruby-lang.org/en/downloads/

The mirror of the Ruby source tree can be checked out with the following command:

$ git clone https://github.com/ruby/ruby.git

There are some other branches under development. Try the following command to see the list of branches:

$ git ls-remote https://github.com/ruby/ruby.git

You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source) if you are a committer.
