Bug #6950: ruby-mode: comint-previous-input does not work

• Status: Third Party's Issue

[cinsk (Seong-Kook Shin)]

On RVM irb with ruby 1.9.3-p194, the prompt is somewhat different from irb with ruby 1.8.x

On ruby 1.8, the prompt looks like:

irb(main):001:0> _

On ruby 1.9.x, the prompt looks like:

ruby-1.9.2-p180 :001 > _

Since misc/inf-ruby.el has regular expressions that only parse "irb(...)>" prompt,
M-p or M-n command do not work properly.

Solution:

1. replace the initial value of 'inferior-ruby-first-prompt-pattern' and 'inferior-ruby-prompt-pattern' to
   following:

(defvar inferior-ruby-first-prompt-pattern "^\(?:irb(.*)[0-9:]+0\|ruby[-0-9.a-z]+ *:[0-9]+ *\)> *"
"first prompt regex pattern of ruby interpreter.")

(defvar inferior-ruby-prompt-pattern "^\(?:\(irb(.)[0-9:]+[>"'] *\)+\|ruby[-0-9.a-z]+ *:[0-9]+[ "']> *\)"
"prompt regex pattern of ruby interpreter.")

Additionally, perhaps your problem is your .irbrc? My irb prompt is unchanged since 1.8.7.

1.9.2-p290:

irb(main):001:0> RUBY_VERSION
=> "1.9.2"
irb(main):002:0> RUBY_PATCHLEVEL
=> 290

1.9.3-p194:

irb(main):001:0> [RUBY_VERSION, RUBY_PATCHLEVEL]
=> ["1.9.3", 194]

2.0.0-r36819

irb(main):001:0> [RUBY_VERSION, RUBY_REVISION]
=> ["2.0.0", 36819]

=end

This is RVM at work: https://rvm.io/workflow/irbrc/

$ rvm use system
Now using system ruby.

$ irb
irb(main):001:0>

$ rvm use 1.8.7-p302
Using /home/zander/.rvm/gems/ruby-1.8.7-p302

$ irb
1.8.7 :001 >

$ rvm use 1.9.3
Using /home/zander/.rvm/gems/ruby-1.9.3-p194

$ irb

Oh, I should add that my .irbrc is empty here.

Many thanks. I'll modify the .irbrc right away.
