Is Powershell -sta (apartment state) preferred? -


i've been dabbling in powershell (2.0) past several months , love use modernize , standardize of processes @ work - dos based processes. because of nature of work, there around 100 executions of same script(s) going @ once.

first--is powershell "safe" use in manner? have seen -sta execution option - preferred method of working powershell when executing number of same script simultaneously, or used when absolutely necessary? in searching, haven't come answer "when should use apartment state?" believe if not of scripting intend not threaded.

thanks in advance can shed light on powershell apartment state!

in psv2, console host runs mta, , ise runs sta. in psv3 console defaults sta.

you can see apartment state this:

[system.threading.thread]::currentthread.getapartmentstate()

the time need use sta when using classes in .net deal com objects use e.g. system.windows.forms.clipboard.

there 2 ways know of change sta:

powershell.exe -sta -file myscript.ps1

or

$ps = [powershell]::create() $rs = [runspacefactory]::createrunspace() $rs.apartmentstate = "sta" $rs.threadoptions = "reusethread" $rs.open() $ps.runspace = $rs $ps.addscript( { ([system.threading.thread]::currentthread.getapartmentstate()) } ).invoke()

so question why psv2 console mta instead of sta? when want know why ps team made decisions refer bruce payette's powershell in action book. unfortunately didn't why. said there com objects require sta , if script doesn't work try re-running sta.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
