TextMate not working with current Ruby/Rails? - ruby-on-rails

I'm trying, desperately, to get TextMate (via drnic's Ruby on Rails.tmbundle)to take me to Rails source when I highlight a term. Supposedly I can highlight a function and type control-f (^f) but when I do I just get a yellow sheet full of errors (below). Anyone know how to fix? and/or a better way to quickly get to source of a gem?

Using:
TextMate: 1.5.10
Rails: 3x (tried with 3.0.7, 3.1.rc1, 3.1.rc3)
RVM: 1.6.20
Ruby on Rails.tmbundle: HEAD
It used to work with system Ruby (2.3.x). But when I set TextMate's TM_RUBY shell variable to: /Users/meltemi/.rvm/bin/rvm-auto-ruby in TextMate advanced prefs as per these instructions...things broke.

I had the same problem and fixed it: You need to update the TextMate configured path at TM_RUBY to a ruby path in RVM that is compatible. For me:
.../.rvm/rubies/ruby-1.9.3-p327/bin/ruby
works as a compatible version of Ruby for TextMate, for example. You need to set it to an explicit package of Ruby in RVM, because otherwise you're letting it pick up RVM's default, which is likely further along than TextMate was tested against.
Do:
rvm list
to see what you have installed, then do:
which ruby
to see what the auto-ruby is picking up. Then pick something explicit instead of it that works.

I use gemedit or gem-open, whichever I think to install when I'm setting up a machine. They work quite well for this purpose, though I can see how it'd be nice to be able to get directly to the source in one click. Rubymine does this, too, but it's not free.

undefined method `set_params' for OpenSSL::SSL::SSLContext

I've created a gem called kmdata that has an executable. When running bundle exec kmdata decot.7 from within my gem's folder everything works fine. After releasing the gem to rubygems I ran gem install kmdata (in a new window). I then tried to run kmdata decot.7 and I get the following

The line in lib/kmdata.rb is

Update #1
This only appears to be an issue when using 2.0. If I run the same command in 1.9.3 then everything works as expected.
You likely need to include this line (e.g., at the beginning of your file):
require 'openssl'
I had this error on 2.0, and adding this line fixed it. Maybe your 1.9.3 has some configuration/gem that implicitly requires that?
Just out of the blue, but have you configured Net::HTTP to use an SSL connection?
Using Net::HTTP.get for an https url
Here's another person having the same problem...no mention that it's a solution, but try it out: https://www.ruby-forum.com/topic/4417738
This looks like an error in Net::HTTP...are you using the most recent version of the gem?
If I were you, I would focus on:
undefined method `set_params' for #<OpenSSL::SSL::SSLContext:0x007fff31d59d18> (NoMethodError)
I think you could have your gems organized in such a way that there's either something not being included, or you have two classes or methods with the same name, and the wrong one is now being chosen.
I've had something like this happen a couple of times.
Simply put, it's probably going to end up being a scope thing - a require / include, or a duplicate method.
If I'm right, there's not much we can do to help - without access to your computer.
I hope you find it. I would recommend doing some grepping/searching through files for method names, class names etc. if you haven't already.
Edit:
looking back, it seems like you're just dealing with stock code.
If that's the case, try uninstalling all versions of ruby, and then re-installing 2.0.0. You'd be surprised - I've had 1.9.3 do something like this when they are both installed.

Any idea how to fix it? Thanks
You have invalid YAML code somewhere. I mean invalid for Psych (the new ruby YAML parser).
If you cannot (or don't want to) fix your YAML code, try to load the old YAML parser (syck), adding this at the beginning of config/boot.rb
require 'yaml'
YAML::ENGINE.yamler = 'syck'
It's just a 'quick and dirty' fix, I know
My regular Rails 3 App also had this problem, because I was using a localized yaml File for Date/Times.
As you can see in this commit https://github.com/rails/rails/commit/dc94d81
this can be easy "fixed" by placing the array in seperate lines.
- order: [ :year, :month, :day ]
18 + order:
19 + - :year
20 + - :month
21 + - :day
A slight tweak on Paul Raupach's answer which, when run from a directory, finds all *.yml files recursively in all sub-directories and tests the file. I ran it from my Rails root dir.
require 'yaml'
d = Dir["./**/*.yml"]
d.each do |file|
begin
puts "checking : #{file}"
f = YAML.load_file(file)
rescue StandardError
puts "failed to read #{file}: #{$!}"
end
end
The root cause was described on many places and I will summarize it again.
There are two default yaml parser Psych is the new one, the one you should be using. Syck is the old one, its not maintained and dying, its currently used as fall back for when there is no libyaml present (non-linux systems usually).
The important thing is you have some invalid yaml somewhere. It is most probably in your translation files (I had unquoted strings strating with %). Just try loading all your yml files with YAML.load_file on the production box and you will see which one is the broken one.
I had this problem because i had used a tab instead of spaces
It's best to fix your YAML files
Here is how using irb so you don't need the rails console which is probably not working:
require 'yaml'
YAML::ENGINE.yamler = 'psych'
YAML.load_file('config/locales/xxx.en.yml')
you'll get a nice output telling you where the issue is:
Psych::SyntaxError: couldn't parse YAML at line 25 column 17

Absolutely fix your yaml code don't just 'mask' the real problem by forcing YAMl to use 'syck'. I had this same problem and found malformed yml statements in my localization files. If you just force using the older parser then you will not get the benefits of all the work on the new parser elsewhere in your project.
The problem with the original question was in RedCloth. I was experiencing the same issue and simply updating to the most recent version of the RedCloth gem (Currently 4.2.7) fixed the issue.
The above advice from Honza and FlyboyArt is sound and you should fix any custom YAML you have, but with RedCloth being as popular as it is, most users finding this question who also use RedCloth should make sure their GemFile has this line added:
gem 'RedCloth', ">= 4.2.7"
For others reading this, I got this error after making a typo in my database configuration - /config/database.yml
It's a bundler 1.0.10 issue: details here
Try just to downdate bundler
What fixed it in my cause was indeed malformed YAML translation file in:
config/locales/bg.yml
Corrected the YAML mistake and it was all fine. :-)
For those pursuing this issue I have just found that my database.yml was triggering this error because it had no space between the password: keyword and the password. An almost invisible error, and with a database.yml that had worked without errors on an earlier version of rails.
I got this error from trying to connect to a remote db with the password 'p#ssword' and figured out that psych doesn't like the '#' symbol. Changed the DB password and problem solved.
I had this problem. My problem was I had an extra tab in my database.yml file.
I came across this as I was using the r18n library in a Sinatra app I'm building, and in my translation file I had the following:
day: !!pl
0: 0 days
1: 1 day
n: %1 days
which used to work just fine in an older project under Ruby 1.8.7, but which was failing under Ruby 1.9.3.
An answer by #SB gave me the clue I needed to work out my problem. The newer YAML was balking at the %1. Some quick digging and an experiment with irb and I now know that the newer version of the YAML parser requires you to put quotes around strings that start with %1, so I just changed my translation to be
day: !!pl
0: 0 days
1: 1 day
n: "%1 days"
and voila - nasty error message vanished.
For my case, it is not a Bundle issue: (Ruby 1.9 is assumed)
Ruby, by default, uses 'psych' (newer and maintained yaml library linking to the C library: libyaml) if libyaml is present
Otherwise, Ruby uses 'syck' (old and not maintained)
YAML::ENGINE.yamler= 'syck' will thus forces Ruby to use 'syck' on a machine where 'psych' is also installed
More info here: require "yaml" doesn't use psych as default
I manage to fix this problem by installing gem psych inside group :development and :test.
gem 'psych'
I had the same issue with ruby 1.9.2-p180 , going to 1.9.2-p290 solved this for me
Though the answer given by #Vicvega may or may not work (Didn't test it) it goes against Rails and Ruby common principle "Convention over configuration" and should be treated with care (and even more in collaborative work),,, even though the "configuration" in this case is not great
so my vote goes (If i could vote) for those who proposed to eliminate the syntax errors in the YAML files.
now... to solve the error, for me it was kind of a newby error, I didn't have the locale file which I had defined to be the default in Config/application.rb in my Config/locales directory
happy coding
Need to check .yml files for error, I have found problem in my database.yml
I had a similar issue with a malformed YAML translation file. It used a variable before defining it. The following was wrong:
...
messages:
...
<<: *errors_messages
...
messages: &errors_messages
...
It had to be changed to:
...
messages: &errors_messages
...
messages:
...
<<: *errors_messages
...
Then it started working again.
In my case there were 2 issues.
As mentioned by #stwienert, the array representation was an issue.
One more thing was, if a String started with a %{var} I received a Parse exception. I had to change the strings accordingly to avoid beginning with %{var}
For example if the string was
%{user_name} welcome to %{application_name} -- This threw an error
To fix it I had to change it to
Hi, %{user_name} welcome to %{application_name}
Hope this helps someone.
Regards,
Shardul.
Well, just in case this helps...
What I did:
- select all and copy from https://github.com/svenfuchs/rails-i18n/tree/master/rails/locale/es.yml into a new es.yml with notepad++
- tried to watch this new file with netBeans IDE text editor, I got a warning about safe load with utf8 (cannot recall the exact text). Hence did not open it with this text editor.
- switched the local thru configuration/application.rb i18n
- when I loaded a irb page I got "couldn't parse YAML at line 0 column 0" referring to Psych. - Went to IRB and loaded the file with syck it was ok; switched to psych and got same error.
How I solved it:
- went back to copy the contents from https://github.com/svenfuchs/rails-i18n/tree/master/rails/locale/es.yml but this time I pasted it in a newly created file with netBeans editor.
- restarted webRick.
- problem solved.

Remove unused databases from database.rb.
If you use MySQL and there is no PostgreSQL then delete PG database code from databases.yml.
Pshych parse is suck to the core. I am not sure if this is elegant solution but i manage to fix this problem by uninstalling it.
gem uninstall psych
I had a really, really strange problem because I had spaces after. E.g.:
title: "NASA"
Did not work, but
title:"NASA"
Did.
If you're like me and facing a project (inherited) with hundreds of fixtures a few lines of Ruby can save you hours:
require 'yaml'
d = Dir.new('test/fixtures/')
d.each do |file|
begin
f = YAML.load_file('test/fixtures/' + file)
rescue StandardError
puts "failed to read test/fixtures/#{file}: #{$!}"
end
end
Just put it in your Rails root and run it, trash it when you're done.
For other people looking at this I found the issue in rerun.txt which was being called by config/cucumber.yml in a Rails app. rerun.txt was configured to store the most recent cucumber failing test and I had somehow entered weird characters for a cucumber test in the console.
That was hard to find. Wish I had seen Glenn Rempe's answer a while back.
One of the possible causes is mapping values are not allowed in this context at line ...
Here is an incorrect YAML example (user: should not contain any value actually, because it contains children items some_key and some_other_key)
customer: Customer
user: User
some_key: value
some_other_key: value 2
It's not a trivial task to find such issue especially if you have a huge YAML file.
I've created a pretty simple regexp to detect such things.
I checked it in RubyMine
^(\s+)['"\w]+:\s?['"\w]+.*\n\1\s\s
Be careful! It doesn't work correct with special chars like å ø æ etc.
Let me know in comments if it worked for you :)

reason for "RuntimeError (can't add a new key into hash during iteration)" from Mongo?

Our application is a Rails application running on MongoDB via mongoid. We are seeing this error intermittently:

It seems like it happens when I am running any sort of [MongoidModel].collection.group() command. The stack trace seems to indicate that the problem is somewhere within mongo/mongoid internals. What's more, it is only a problem on our production environment, so it's very hard to isolate and debug.
We are using these gems:
mongo 1.3.1
mongoid 2.0.1
Has anyone run into this before?
After some further investigation, it looks like the newrelic
rpm_contrib gem itself was the culprit. Usually when I see that in a
stack trace I just ignore it since newrelic is involved in logging
errors, but in this case it was actually causing the error. We
happened to upgrade the gem to 2.1.4 yesterday afternoon because we thought
newrelic was acting a bit flaky, which is about the time we stopped
seeing errors in production. Looking into the first line of the stack
trace, that line newrelic code was modified to prevent race
conditions, which jives with the RuntimeError. So, I'm going to assume
this is fixed and is not in fact related to mongo itself.

It seems there's a problem with a file, deprecated_block_helpers, which is not found in Rails. Anyone knows how to solve this problem?
Actually this is a bug in Rails 3.0.5 (it has been fixed in edge).
DeprecatedBlockHelpers is autoloaded in ActionView::Helpers, but the file itself was removed in 9de8305
This helper was designed to show a deprecation notice for using <% %> instead of <%= %> (or - instead of = in haml) for certain blocks. I'm not sure exactly which blocks the deprecation is for, but maybe take a look through your templates and see if you can trial-and-error this into working.
Alternatively, you can vendor Rails and remove the DeprecatedBlockHelpers autoload, or track edge Rails.

Undefined method '>>' for class 'Date' in Rails 3 on Ruby 1.8.7/1.9.2

I'm running a Rails 3.0.0 application on Ruby 1.8.7-p174. Everything was going swimmingly until I tried to run some tests:
/Users/avand/.rvm/gems/ruby-1.8.7-p174/gems/activesupport-3.0.0/lib/active_support/core_ext/date/calculations.rb:9: undefined method `>>' for class `Date' (NameError)
from /Users/avand/.rvm/gems/ruby-1.8.7-p174/gems/activesupport-3.0.0/lib/active_support/ruby/shim.rb:12:in `require'
from /Users/avand/.rvm/gems/ruby-1.8.7-p174/gems/activesupport-3.0.0/lib/active_support/ruby/shim.rb:12
from /Users/avand/.rvm/gems/ruby-1.8.7-p174/gems/actionpack-3.0.0/lib/abstract_controller.rb:6:in `require'
from /Users/avand/.rvm/gems/ruby-1.8.7-p174/gems/actionpack-3.0.0/lib/abstract_controller.rb:6
I took a look into that Calculations class, noting that undef was being called with :>>. But Ruby 1.8.7 Dates don't have a >> method. I figured I'd wrap it with a condition: if respond_to?(:>>). Things broke further along this time:
/Users/avand/.rvm/gems/ruby-1.9.2-rc2/gems/activesupport-3.0.0/lib/active_support/core_ext/date/calculations.rb:91:in `alias_method': undefined method `+' for class `Date' (NameError)
from /Users/avand/.rvm/gems/ruby-1.9.2-rc2/gems/activesupport-3.0.0/lib/active_support/core_ext/date/calculations.rb:91:in `<class:Date>'
from /Users/avand/.rvm/gems/ruby-1.9.2-rc2/gems/activesupport-3.0.0/lib/active_support/core_ext/date/calculations.rb:7:in `<top (required)>'
from /Users/avand/.rvm/gems/ruby-1.9.2-rc2/gems/activesupport-3.0.0/lib/active_support/ruby/shim.rb:12:in `require'
from /Users/avand/.rvm/gems/ruby-1.9.2-rc2/gems/activesupport-3.0.0/lib/active_support/ruby/shim.rb:12:in `<top (required)>'
from /Users/avand/.rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0/lib/abstract_controller.rb:6:in `require'
The second stack trace is Ruby 1.9.2. I'm getting the same error with Ruby 1.9.2 without my respond_to? check as Ruby 1.8.7 with it.
I commented out my Date extensions in lib. This only occurs in the test environment.
Thoughts?
So this may not be the most helpful answer but it's all I've been able to determine so far.
The file in question: activesupport-3.0.0/lib/active_support/core_ext/date/calculations.rb removes the definitions of :>> as you saw. If the file is require twice, the second loading of that file will fail due to the method no longer being defined on the Date class.
So why is this file being required twice? That I'm really not sure of. I've seen that the protection against this can be buggy (if you'd call it a bug, it may just be a limitation) when you specify the file with a full path once and then another time you depend on the LOAD_PATH having the correct folder in it to find you file that way.
I'd look through your code and see what is requiring either rails/all or activesupprt/railstie and hopefully you'll see two separate places that look slightly different. Also see if you're mucking with the LOAD_PATH anywhere between the two places.
