Rails console now includes project name and environment

[sachac]

The Rails console now includes project name and environment in the prompt (https://railsatscale.com/2024-07-11-mid-year-review-irb-and-rails-console-enhancements-in-the-first-half-of-2024/#rails-console-improvements , ex: my-app(prod)>) I think the "\\(^[^%s]+\\)" regex that I'm adding here is a bit heavy-handed, but it makes M-p and M-n work. I figured I'd mention it anyway just in case it's not on your radar yet and just in case someone can come up with a better regular expression.

(setq inf-ruby-prompt-format
            (concat
             (mapconcat
                #'identity
                '("\\(^%s> *\\)"                    ; Simple
                    "\\(^(rdb:1) *\\)"          ; Debugger
                    "\\(^(rdbg[^)]*) *\\)"  ; Ruby Debug Gem
                    "\\(^(byebug) *\\)"         ; byebug
                    "\\(^\\(irb([^)]+)"         ; IRB default
                    "\\([[0-9]+] \\)?[Pp]ry ?([^)]+)"   ; Pry
                    "\\(^[^%s]+\\)"          ; new rails console with project name and environment
                    "\\(jruby-\\|JRUBY-\\)?[1-9]\\.[0-9]\\(\\.[0-9]+\\)*\\(-?p?[0-9]+\\)?" ; RVM
                    "^rbx-head\\)")                  ; RVM continued
                "\\|")
             ;; Statement and nesting counters, common to the last four.
             " ?[0-9:]* ?%s *\\)")
            inf-ruby-first-prompt-pattern
            (format inf-ruby-prompt-format ">" ">" ">")
            inf-ruby-prompt-pattern
            (format inf-ruby-prompt-format "[?>]" "*>" "[\]>*\"'/`]"))

Hi Sacha, thanks for the report.

Here's a bit stricter solution, which might be important for consoles with long outputs, etc. Could you try it out?

And pushed.
