    How to install Gyazo on Ubuntu

    Gyazo is a screenshot-taker that takes a screenshot of a custom area. It is only made for Windows, but can be coded for Ubuntu to. Here is what you do:

    1. Install Imagemagick in the Software Center


    2. Open the Terminal and type "sudo apt-get install ruby" without the quotes. Let it install.


    3. Now open gedit and paste this code in:
    Code:
    #!/usr/bin/env ruby 
    
    # setting 
    browser_cmd = 'firefox' 
    clipboard_cmd = 'xclip' 
    proxy_addr = nil 
    proxy_port = nil 
    
    require 'net/http' 
    
    # get id 
    idfile = ENV['HOME'] + "/.gyazo.id" 
    
    id = '' 
    if File.exist?(idfile) then 
      id = File.read(idfile).chomp 
    end 
    
    # capture png file 
    tmpfile = "/tmp/image_upload#{$$}.png" 
    imagefile = ARGV[0] 
    
    if imagefile && File.exist?(imagefile) then 
      system "convert #{imagefile} #{tmpfile}" 
    else 
      system "import #{tmpfile}" 
    end 
    
    if !File.exist?(tmpfile) then 
      exit 
    end 
    
    imagedata = File.read(tmpfile) 
    File.delete(tmpfile) 
    
    # upload 
    boundary = '----BOUNDARYBOUNDARY----' 
    
    HOST = 'gyazo.com' 
    CGI = '/upload.cgi' 
    UA   = 'Gyazo/1.0' 
    
    data = <<EOF 
    --#{boundary}\r 
    content-disposition: form-data; name="id"\r 
    \r 
    #{id}\r 
    --#{boundary}\r 
    content-disposition: form-data; name="imagedata"; filename="gyazo.com"\r 
    \r 
    #{imagedata}\r 
    --#{boundary}--\r 
    EOF 
    
    header ={ 
      'Content-Length' => data.length.to_s, 
      'Content-type' => "multipart/form-data; boundary=#{boundary}", 
      'User-Agent' => UA 
    } 
    
    Net::HTTP::Proxy(proxy_addr, proxy_port).start(HOST,80) {|http| 
      res = http.post(CGI,data,header) 
      url = res.response.to_ary[1] 
      puts url 
      if system "which #{clipboard_cmd} >/dev/null 2>&1" then 
        system "echo -n #{url} | #{clipboard_cmd}" 
      end 
      system "#{browser_cmd} #{url}" 
    
      # save id 
      newid = res.response['X-Gyazo-Id'] 
      if newid and newid != "" then 
        if !File.exist?(File.dirname(idfile)) then 
          Dir.mkdir(File.dirname(idfile)) 
        end 
        if File.exist?(idfile) then 
          File.rename(idfile, idfile+Time.new.strftime("_%Y%m%d%H%M%S.bak")) 
        end 
        File.open(idfile,"w").print(newid) 
      end 
    }
    The line that says browser_cmd = 'firefox' will open Firefox so if you want it to open Chromium instead replace it with browser_cmd = 'chromium-browser'

    Now save it as gyazo.rb

    4. Right-click gyazo.rb and click Properties. And under Permissions check the Execution box.


    5. Drag it to your navbar on the top and when you want to take a picture just click it!


    Enjoy!

    Re: How to install Gyazo on Ubuntu

    i am trying to do this and it doesn't appear to be working. I am using Xubuntu 12.04 and there is 2 different versions of ruby, there's 1.8 and 1.9.1, I installed the latest one. I changed the execute bit on the file but when I double click it nothing happens. If I run it from the command line, it returns this:

    Code:
    /usr/local/bin/gyazo.rb:82: can't find string "EOF" anywhere before EOF
    /usr/local/bin/gyazo.rb:43: syntax error, unexpected $end, expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
    data = <<EOF 
                ^
    Can you help please?
