Error on Ruby 1.9.3 #167

Stwissel · 2014-03-14T08:24:41Z

Installed mustache using

$ sudo gem install
$ mustache --version
Mustache v0.99.5

Executing:

$ cat test.yml test.mustache | mustache

I get the error:

Hm, I'm not sure what might be the problem. Maybe the wrong version of Psych?
I tried replicating with ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-darwin12.3.0] but was unable to.

Hi Ricardo,

Thx for looking into this. I'm still on Ubuntu 12.10 which is Ruby 1.9.1
Guess I have to learn how to install an older version of mustache

Hi.

Same problem here, did you fix this issue?

$ mustache --version
Mustache v0.99.5
$ ruby --version
ruby 2.1.0p0 (2013-12-25 revision 44422) [i686-linux]

bfontaine · 2014-04-08T07:19:55Z

In Ruby 1.9.3, the default YAML parser switched from Syck to Psych. Syck provides each_document, but not Psych, and this cause this error. The following piece of code:

require 'yaml'

doesn’t require the same module in Ruby <1.9 and Ruby >=1.9. From the docs:

Syck was the original for YAML implementation in Ruby’s standard library developed by why the lucky stiff.

If you prefer, you can still use Syck by changing the YAML::ENGINE like so:
YAML::ENGINE.yamler = 'syck'
# switch back to the default Psych
YAML::ENGINE.yamler = 'psych'
In older Ruby versions, ie. <= 1.9, Syck is still provided, however it was completely removed with the release of Ruby 2.0.0.

Mustache takes care of this issue, as we can see in the code, but this was committed after the last release of the gem, which occurred 3 years ago. So the solution is to install it from source. Add the following to your Gemfile:

gem 'mustache', :git => 'git://github.com/defunkt/mustache.git'

Then use bundle install and it’ll work!

If you don’t use Bundler or want to install the gem globally, clone the repo and install the gem from it:

git clone https://github.com/defunkt/mustache.git
cd mustache
gem build mustache.gemspec
gem install ./mustache-0.99.5.gem

sagotch · 2014-04-08T07:46:47Z

Install from sources worked for me 👍

locks · 2014-04-17T11:44:55Z

Thank you for the insightful post @bfontaine. I'm closing this issue since it appears to be fixed in master, and continue work on the 0.99.6 release.

Stwissel · 2014-04-17T15:47:57Z

Installed it from source, updated Ruby, didn't work:

       ruby --version
       ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-linux]

       mustache --version
       Mustache v0.99.5

       $ cat testcombined.mustache | mustache

and the error is:

/home/stw/.rvm/gems/ruby-2.1.1/gems/mustache-0.99.5/bin/mustache:78:in `read': no implicit conversion of nil into String (TypeError)
    from /home/stw/.rvm/gems/ruby-2.1.1/gems/mustache-0.99.5/bin/mustache:78:in `process_files'

so something is still amiss

@Stwissel 2.1.1p76 != 1.9.3, one step at a time :P

Stwissel · 2014-04-17T16:03:11Z

Ok - sorry. Forgot to mention what I did:

Installed Mustache from source

Tried with

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

-> Get the error:

Install ruby 2.1.1
Install mustache from source again
Test and get above error

@Stwissel I seem to have introduced that bug by merging #169 in d6f9d79, apologies.
I'll try to sort it out.

locks · 2014-04-17T17:56:50Z

@Stwissel can you give it another go?

Stwissel · 2014-04-18T03:19:22Z

Upps... sorry - last test was wrong. Forgot to reinstall the gem in Ruby 2.1.1. Works like a charm now. So - fixed. You just need to specify in the upcoming gem definition that you need ruby 2.x

k-bx · 2014-09-11T17:35:03Z

Just FYI, issue is present on Ubuntu 14.04 if you apt-get install ruby-mustache. I think it's quite important to keep mustache usable from apt-get.

Thanks!

Stwissel · 2014-09-12T00:52:17Z

I just did apt-get install mustache and it worked

@Stwissel just tried on my own Ubuntu 14.04 (previously tried on server), same error:

➜  tmp  cat ./tpl.yaml 
---
foo: "bar"
---
➜  tmp  cat ./tpl.mustache 
Hello, {{foo}}
➜  tmp  mustache ./tpl.yaml ./tpl.mustache

k-bx · 2014-09-12T12:40:28Z

@Stwissel reproduced inside fresh docker image http://paste.ubuntu.com/8326823/

locks · 2014-09-12T12:56:33Z

That paste is a bit confusing, is the system ruby 1.9.3 or 1.9.1?

k-bx · 2014-09-12T13:13:45Z

@locks what's confusing? It should be reproduceable on any linux with docker installed and ~/tmp/tpl.yaml and ~/tmp/tpl.mustache preserved. You can omit -v option to share directories between host and guest, and write yaml/mustache files by hands if you want to.

Maybe this is more clear:

➜  ~  sudo docker run -t -i --rm ubuntu:14.04 /bin/bash
root@ba1c53a632c0:/# apt-get update -qq && apt-get install -qq ruby-mustache > /dev/null
root@ba1c53a632c0:/# echo $'---\nfoo: "bar"\n---\n' > tpl.yaml
root@ba1c53a632c0:/# cat tpl.yaml
---
foo: "bar"
---

root@ba1c53a632c0:/# echo $'Hello, {{foo}}' > tpl.mustache
root@ba1c53a632c0:/# cat tpl.mustache 
Hello, {{foo}}

You can see ruby version also.

@k-bx I'm not familiar with Ubuntu/etc, but I just tried installing ruby-mustache in a vm and it's telling me

$ mustache -v
Mustache v0.99.4

Maybe updating the ruby-mustache package solves the problem? I don't know how to go about this.

k-bx · 2014-09-16T14:50:15Z

@locks anyway, if someone is having similar issues, I wouldn't bother and just use something else (it's all mustache!), for example there's python-pystache package for python wrapper around mustache. I've used that one when I had a problem.

k-bx · 2014-09-16T14:51:15Z

@locks (but just if you're very curious -- yes, I can confirm that on my non-vm ubuntu I have same output for mustache -v command)

k-bx · 2014-09-16T14:51:42Z

➜  tmp  mustache ./tpl.yaml ./tpl.mustache
