[WiX-users] Fwd: Unique Short Names?

John Ludlow Wed, 07 Jun 2006 14:00:55 -0700

I have a Ruby script that chops up the filenames to be shorter than 8.3. It's not perfect, but it may help (obviously you need Ruby to run it, but it could probably be ported to .vbs or C# or something).

Anyway, here it is:

# Loops through a WiX project (change the wixfilename variable to specify the filename) to
# * slice the Name attribute if it's too long (non-8.3 compliant)
# * append _x (where x is a number) before the dot in the Name attribute
# * set the LongName parameter to the old value of Name if it fixes the Name parameter as above
# * set the

require 'rexml/document'

include REXML

wixfilename = "test.wxs"

xf = File.open(wixfilename, 'r')
xd = Document.new xf.read
xf.close

#slice everything to 8.3 lengths. For example, myapplication.config will get sliced to myapplic.config

XPath.each xd, "//Wix:File", {'Wix', 'http://schemas.microsoft.com/wix/2003/01/wi' } do |f|

file_name = f.attributes['Name'].split('.')[0]
file_ext = f.attributes['Name'].split('.')[1]

if file_name.length > 8 or file_ext.length > 3
short_file_name = f.attributes['Name'].split('.')[0].slice(0..7)
short_file_ext = f.attributes['Name'].split('.')[1].slice(0..2)

  f.attributes['LongName'] = f.attributes['Name']
  count = 0

  f.attributes['Name'] = short_file_name + '.' + short_file_ext
end

if f.attributes['LongName'] != nil
f.attributes['Id'] = f.attributes['LongName']
else
f.attributes['Id'] = f.attributes['Name']
end
end

#look for duplicates. If it finds any, it will further slice it to 6.3 and append _x, where x is a number.

XPath.each xd, "//Wix:File", {'Wix', 'http://schemas.microsoft.com/wix/2003/01/wi' } do |f|
name = f.attributes['Name']
matches = XPath.match xd, "//Wix:[EMAIL PROTECTED] = '#{name}']", {'Wix', ' http://schemas.microsoft.com/wix/2003/01/wi'}

if matches.length > 1
  count = 0
  matches.each do |m|
   short_file_name = f.attributes['Name'].split('.')[0].slice(0..5)
   short_file_ext = f.attributes ['Name'].split('.')[1].slice(0..2)

   count = count + 1
   m.attributes['Name'] = "#{short_file_name}_#{count}.#{short_file_ext}"
  end
end
end

xf = File.open(wixfilename, 'w')
xd.write xf
xf.close

Hopefully that will help

Please be sure to run MSI validation on your msi files before shipping them to customers. I think you'll find that using the same short files will generate lots and lots of errors. You'll likely also discover many other issues. light in WiX 3.0 automatically runs validation, but in 2.0 you'll need to use an outside tool such as Orca, smoke (from the 3.0 wix toolset) or msival2.

Possibly. If your install ever ends up on a short name system (and you don't have complete control over that) then you're going to be seriously hosed.

I am using the latest wix v2.

Does anyone know if the 'Name' attribute on the <File> element needs to be unique? All of the file's I install I use the appropriate 'Longname' value, but as I 'm having trouble auto-generating short names I have used the same value for the 'Name' attribute for every file and it seems to work fine. Is this likely to cause me problems down the line?
