tj3man raises ruby syntax error

[Frank Dordowsky]

When executing tj3man, I get the following error trace:

I have ruby 2.2.2-1 installed I do not know anything about Ruby, so any help is appreciated.

I have ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux] installed (Fedora 22) and am seeing the same thing.  I'd also appreciate any help with this.

I've fixed this by modifying the following file;

/usr/lib/ruby/vendor_ruby/2.2.0/taskjuggler/KeywordDocumentation.rb

Original file (around line 443);

def generateHTMLSupportLevel

if @pattern.supportLevel != :supported

  [

    P.new do

      newRichText("<fcol:red>#{supportLevelMessage}</fcol>").to_html

    end,

    [ :deprecated, :removed ].include?(@pattern.supportLevel) ?

      P.new do

        useInsteadMessage

      end : nil

    ]

else

to the following;

def generateHTMLSupportLevel

if @pattern.supportLevel != :supported

  [

    P.new do

      newRichText("<fcol:red>#{supportLevelMessage}</fcol>").to_html

    end,

    if [ :deprecated, :removed ].include?(@pattern.supportLevel) 

      P.new do

        useInsteadMessage

      end

    end

  ]

else

I've never done anything with Ruby before so I'm not sure if this is correct but it does seem to get the tl3man documentation working.

That will not render the deprecation warnings. But thanks for trying to
fix it. I've just committed a proper fix that hopefully will eliminate
the problem with Ruby 2.2.2. I don't have this version installed yet, so
I can't test it right now. Please report back if it works or not. The
fix is in the Git repository.

Thanks,
Chris

Hello Chris,

Thankyou very much for the quick response.  I've uninstalled my copy of taskjuggler, cloned the repository and installed from the updated code using the following commands (executed from the newly created Taskjuggler directory);

$ sudo gem uninstall taskjuggler
$ gem build taskjuggler.gemspec
$ sudo gem install ./taskjuggler-3.5.0.gem

The updated tj3man commands now work perfectly on a standard Fedora 22 install (ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux])

Kind regards

James

Sorry for my late answer but I have been offline for the last two weeks. I have applied the fix located on the Git for the file KeywordDocumentation.rb  locally since I prefer to stay with the Archlinux packaging. It works now also for me. Thanks very much for your help.

Hi!
I have found that setting ruby version to 2.0.0 with rvm and then installing taskjuggler v.3.5 with bundler works.
The workflow looks something like this:
1. create a .rvmrc file in your working directory containing the line:
rvm use 2.0.0
2. create a Gemfile with the entry:
source 'https://rubygems.org'

gem 'taskjuggler','3.5.0'
3.run: bundle install
4. bundle exec tj3man

And you are ready to go :)
