PDF Forms Editing in OS X

I needed a simple PDF forms editor so that I can fill in and send forms via email and did not want to use the stone age process of printing the PDF out, filling it in, scanning it back in and then sending off the digitised copy.


FormulatePro fits the bill perfectly

Bundling jruby app with rawr:bundle:exe dies with 'private method `split' called for nil:NilClass' in

I have a little jruby SWT app that I'm trying to bundle up in its own little cocoon with rawr but I keep getting the following:

C:\nms-helper4.git>rake rawr:bundle:exe

Taking the advice presented at the end there I run it again with:

Aah, so things are coming undone in exe_bundler.rb:92:

 80       if Platform.instance.using_windows?
 81         # Check for FAT32 vs NTFS, the cacls command doesn't work on FAT32 nor is it required
 82         output = `fsutil fsinfo volumeinfo #{file_dir_name.split(':')[0]}:\\`
 83         # fsutil can only work with admin priviledges
 84         raise output if output =~ /requires that you have administrative privileges/
 85         # ===== Sample output of 'fsutil fsinfo volumeinfo c:\'
 86         # Volume Name :
 87         # Volume Serial Number : 0x80a5650a
 88         # Max Component Length : 255
 89         # File System Name : FAT32
 90         # Preserves Case of filenames
 91         # Supports Unicode in filenames
 92         if 'NTFS' == output.split("\n")[3].split(':')[1].strip
 93           sh "echo y | cacls \"#{file_dir_name}/launch4j/bin-win/windres.exe\" /G \"#{ENV['USERNAME']}\":F"
 94           sh "echo y | cacls \"#{file_dir_name}/launch4j/bin-win/ld.exe\" /G \"#{ENV['USERNAME']}\":F"
 95         end
 96         link_launch4j_bin('win', file_dir_name)

Line 92 seems to rely on what happens in line 82 where we try and get some filesystem info based on the drive name. The bit that tries to determine the drive letter uses '\\' at the end which is the issue. If you change that to '\\\\' you get things to work as they should again:

 82         output = `fsutil fsinfo volumeinfo #{file_dir_name.split(':')[0]}:\\\\`

Somehow the double backslash is not making it to the shell correctly from the backticks being called. Adding the extra set of backslashes saves the day:

Reality restored.

From what I can see I am running the latest rawr gem:

C:\nms-helper4.git>jruby -S gem search -r rawr

*** REMOTE GEMS ***

drawr (1.0.1)
rawr (1.4.5)

C:\nms-helper4.git>jruby -S gem list rawr

*** LOCAL GEMS ***

rawr (1.4.5)

Checking the master branch on github though shows this file is no longer the same and the issue has been fixed:

81      if Platform.instance.using_windows?
82        # Check for FAT32 vs NTFS, the cacls command doesn't work on FAT32 nor is it required
83        volume = file_dir_name.split(":").first.upcase + ':'
84        output = `fsutil fsinfo ntfsinfo #{volume}`
85        # fsutil can only work with admin priviledges
86        raise output if output =~ /requires that you have administrative privileges/
87        raise output if output =~ /Error:/
88        if 'NTFS' == output.split("\n")[0][0..3]
89          sh "echo y | cacls \"#{file_dir_name}/launch4j/bin-win/windres.exe\" /G \"#{ENV['USERNAME']}\":F"
90          sh "echo y | cacls \"#{file_dir_name}/launch4j/bin-win/ld.exe\" /G \"#{ENV['USERNAME']}\":F"
91        end
92        link_launch4j_bin('win', file_dir_name)

The Rakefile refers us to 'rawr/rawr_version' that is:

1   module Rawr
2     VERSION = "1.5.0"
3   end

Looks like the latest version of the project on github has not made it into the wild as yet.

Resizing your OS X VMWare Fusion Virtual Disk

Assumptions:

• New disk size is 40GB.
• Current virtual disk is foo.vdmk
• Current VM image is at /Users/foo/Documents/Foo.vmwarevm

Quick recipe:

• Open up a teminal window
• Run: cd /Users/foo/Documents/Foo.vmwarevm && /Library/Application\ Support/VMware\ Fusion/vmware-vdiskmanager -x 40GB foo.vmdk
• Resize the host OS with a third party tool. In my case I was resizing a NTFS partition with XP installed on it. Easeus Partition Manager home Edition did the trick for me.
