Logback config, puppet and application versions -


i busy testing new approach managing java application uses logback on puppet-managed host, , wondering if had advice on best approach this. stuck catch 22 situation.

the java application deployed host automated system (ci). deployment writes application version number file (e.g. /etc/app.version may contain "0001")

the logback config file (logback.xml) managed puppet.

i trying configure application include it's version number in logging layout (e.g. <pattern>version: %version%</pattern> . however, not sure on approach, there isn't "include" function logback config file (to include file version number logback config). @ same time, don't see way puppet client-side template build, using host-side file (i've tried using template approach, template compiled on puppet server side).

any idea's on how working?

i write custom fact. facts executed on client.

eg:

logback/manifests/init.pp

file { '/etc/logback.xml':   content => template('logback/logback.xml.erb') }

logback/templates/logback.xml.erb

... <pattern>version: <%= scope.lookupvar('::my_app_version') %></pattern> ...

logback/lib/facter/my_app_version.rb

facter.add('my_app_version')   setcode     begin        file.read('/etc/app.version')     rescue        nil     end   end end

hope helps. think in puppet < 3.0 have set "pluginsync = true" in puppet.conf work.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
