looksee's Issues

Add support for truffleruby.

excellent truffler on his toword 1.0.0 way. (1.0.0 RC6 soon), it now support mysql2 pg, nokogiri etc, i think maybe it is the time have a try in little ruby production project.,

i want to know weather it is possible to worked with Looksee.

Thanks

Doesn't plays well with Wirble

When using looksee and wirble, the output of the lookup path is broken (I think it's causes by the colorization).

Support opal.

Following link is opal-irb, a full-featured Ruby 2.1.x implement in browser.

http://fkchang.github.io/opal-irb/index-embeddable.html

Because it exist a ruby run-time (+stdlib and corelib), and can run external
ruby file, So, I think it should work well with looksee.

Prepended modules confuse looksee

Ruby 2.3 Support

Hi oggy,

looksee does not work for the new 2.3:

(Object doesn't support #inspect)

Can not looksee ActiveRecord instance objects anymore after upgrading to rails 4.1.0. It was working fine with 4.1.0rc. I have not added any new gems to the project but some of outdated gems are updated in the process.

AnyClass.ls works fine. AnyClass.new.ls returns empty printing out (Object doesn't support #inspect).

Ruby 2.5 Support?

Thanks

Ruby 1.9.2 'const_missing': uninitialized constant IRB

I get this error running under rvm 1.9.2
/Users/george/.rvm/gems/ruby-1.9.2-p0/gems/rake-0.8.7/lib/rake.rb:2503:in `const_missing': uninitialized constant IRB (NameError)

require-ing in irbrc shows warning "can't alias ls from irb_ls"

When one requires this gem in the irbrc file, you get a warning on irb startup, from ruby 2.7 onwards (tested in 2.7.1 and 3.0.0):

% irb -f -r'looksee'
irb: warn: can't alias ls from irb_ls.
irb(main):001:0>

If you require the gem after irb has finished loading, there is no issue.

% irb -f
irb(main):001:0> require 'looksee'
=> true
irb(main):002:0>

Main difference seems to be the result of show_source 'ls' (in REPL). For the startup (and command line) case it shows Looksee, otherwise irb/extend-command.rb.

Warning goes away if one adds Looksee.rename :_ls to irbrc ... but considering this happens for a straightforward installation, it seems like that should not be necessary. Would be great if require-ing looksee in irbrc and during REPL would behave the same way.

Probably relevant:

on ruby-1.9.3-preview1 looksee won't work

Hi,

I got this error: looksee-1.0.2/lib/looksee/mri.so: undefined symbol: RCLASS_M_TBL

also this on startup of the rails console: looksee-1.0.2/lib/looksee/adapter.rb:6: Use RbConfig instead of obsolete and deprecated Config.

Looksee[] and ls method is not work in ActiveRecord instance.

When in rails console, ls and Looksee[] seem like not work on ActiveRecord instance in some case.

[req] Find out where a object is defined?

Looksee is amazing. If you're busy–just tell me where to add this feature, and I'll be happy to dig around and try my luck :).

It's so great for digging up the unbearable. One thing I'd like to request–or maybe there's already a way?–is for me to figure out where a class was defined. Generally I can just #ls and pick a method from the, or do stuff.edit 'initialize'. It'd be really helpful to be able to do something.edit true or something.edit :defined etc.

Thank you for making Looksee. It's a real boon for devops data trolls like me.

Following is a reproduceable one file ruby script to reproduce this.

this issue may caused by roda plugins system, anyway, here have a blog maybe help on this.

Thank you.

Invalid gemspec file

similar to this issue:
rubygems/bundler#1235

bundler version: 1.0.18
rake version: 0.9.2
ruby version: ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

Looksee 4.0 not worked for 2.2

It work well with Ruby 2.3.0

But when switch back to 2.2, with previous compiled version so files
But update rb files to newest version, it seem like not work.

Using /home/zw963/.rvm/gems/ruby-2.2.4

*** LOCAL GEMS ***

Looksee fails with instances of classes that use the equalizer gem

Let's say we have the following class that uses the equalizer gem:

require 'equalizer'

class GeoLocation
  include Equalizer.new(:latitude, :longitude)

  attr_reader :latitude, :longitude

  def initialize(latitude, longitude)
    @latitude, @longitude = latitude, longitude
  end
end

Looksee fails with objects of this class like this:

2.1.1 :001 > require 'looksee'
 => true 
2.1.1 :002 > x = GeoLocation.new(1,2)
 => #<GeoLocation latitude=1 longitude=2> 
2.1.1 :003 > x.ls
(Object doesn't support #inspect)
 =>  
2.1.1 :004 > x.inspect
 => "#<GeoLocation latitude=1 longitude=2>"

problem in rails console

when I run lp [] in irb everything is fine, but when running the same command in rails console I get something like this:

ESC[1;37mArrayESC[0m
ESC[1;32m&ESC[0m ESC[1;32mcompact!ESC[0m ESC[1;32minclude?ESC[0m
ESC[1;32mrassocESC[0m ESC[1;32mto_aESC[0m

the ansi colors are working fine in irb but in rails console they just make a mess in way that makes it unusable!

why the newgem dependency?

$ irb
irb(main):001:0> require 'rubygems'
irb(main):002:0> require 'looksee/shortcuts'
Gem::LoadError: Could not find RubyGem newgem (>= 1.5.1)

$ sudo gem install newgem
ERROR:  Error installing newgem:
hoe requires RubyGems version >= 1.3.1 

$ sudo wajig install rubygems
rubygems is already the newest version.

I shouldn't need to update my rubygems manually just to use looksee

build on ruby 3.2.0?

Thanks.

Bus Error when lp called on Fixnum/TrueClass/FalseClass/NilClass/Symbol instances (1.8.7, 1.9)

This also happens for Fixnums, false, nil, and literal symbols.

This problem happens here:
VALUE Looksee_internal_class(VALUE self, VALUE object) {
return RBASIC(object)->klass;
}

Fixed here:

Will send a pull request.

Ruby 2.4 support?

See #42, Seem like Ruby 2.4 is no binary library compile need, right ?

Thanks.

Looksee can't displays well when using with fancy_irb on Ruby 1.9.2

After I installed funcy_irb, and I turned it on in irbrc. 'ls' method starts displays output incorrectly. But it's so strange, it's only Ruby 1.9.2. When I tried on Ruby 1.8.7, it works fine.

It doesn't work on Ruby 1.9.2?

After I install looksee on Ruby 1.9.2 in my ubuntu. I got the error:

can not use Looksee for action_mailer

Hi, I tried to see all method of ActionMailer::Base using ls, but it give you error AbstractController::ActionNotFound: The action 'ls' could not be found for ActionMailer::Base. It is related with method_missing from ruby feature. it is the method_missing of ActionMailer::Base :

      def method_missing(method_name, *args) # :nodoc:
        if action_methods.include?(method_name.to_s)
          MessageDelivery.new(self, method_name, *args)
        else
          super
        end
      end

does looksee not support for class that using method_missing? 😄
thanks.

JRuby.jar fails to load

Changing the file name from jruby.jar to JRuby.jar fixes the problem

Ruby 2.7 will be release soon, thank you.

The default grey text on output hard to read on default white terminal

such as "=> String"

I saw the color overrides, but I didn't see a option to override that color.

Add a shorthand for Object.instance_method(:ls).bind(object).call

For dealing with proxy objects that delegate everything -- including ls -- via method_missing. Looksee.ls(object, *args) perhaps.

Also make this work for things that inherit BasicObject without Object.

not output correct when use with irb. (it works with pry)

I consider this is not same reason as https://github.com/oggy/looksee#ansi-escapes, because outout not same, and when i set export LESS='-R' instead, still get same result.

But ls works quite well with pry, test it on ruby 2.7.1 and ruby 3.0.2

Thank you.

Looksee for Wirble's Tab Completion

Wirble has method tab completion, but it's a flat list. I wonder if Looksee could hook into that and become a better tab completion?

Pagination would be nice too.
