log_buddy and Windows
I recently started playing around with the log_buddy gem for Rails and because my development machine is on windows, the “d” method wasn’t playing nice with some paths. it didn’t like paths that included the drive letter.
this is a sample of a line that would cause log_buddy to barf. it just so happens to also be the line that causes the error. 
c:/ruby/lib/ruby/gems/1.8/gems/log_buddy-0.0.5/lib/log_buddy.rb:98:in `read_line'
the original line looked like this…
file, line_number = frame.split(/:/, 2)
the fix is to replace that line with
file, line_number = frame.reverse.split(/:/, 3)[1..2].map(&:reverse).reverse
yeah. ugly, and maybe could be written better but it works for me.
now if only I could get log_buddy to output good inspections of objects I toss to it… like “current_user”. I’m prolly using it wrong right now, but this isn’t helpful…
current_user = '#<User:0x47143d8>'
just saying.
UPDATE: I monkeypatched log_buddy to fix this functionality. I created a “RAILS_ROOT/lib/log_buddy_extensions.rb” file with the following code.
class LogBuddy
private
# Return the calling line
def self.read_line(frame)
file, line_number = frame.reverse.split(/:/, 3)[1..2].map(&:reverse).reverse
line_number = line_number.to_i
lines = File.readlines(file)
lines[line_number - 1]
end
endand I figured out that the “current_user” line above shouldn’t be …
d { current_user }
it should be
d { current_user.inspect }
that outputs what I want …
current_user.inspect = '#<User id: 1, login: "matte", email: "matte@localhost", crypted_password: "...", salt: "...", created_at: "2007-08-30 18:23:32", updated_at: "2008-07-08 18:57:45", remember_token: "...", remember_token_expires_at: "2008-07-22 18:57:45", name: "...", password_reset_code: nil, company_id: 2, active: true>'
Note to everyone using Apache and the XSendFile module. If you’ve included the module and are getting 0-byte files, like I was today, make sure you have the following lines in your VirtualHost config
