erb - How to test templates with hiera data locally? -

-

I'm trying to get an erb template file and remove a way to use Hierra data (even here That also use a yaml file)) and just templates to create a file with the replaced values.

Have you ever tried to do something like this? My first thought is to write a ruby ​​script, but maybe this is a simple solution.

Thanks in advance.

Edit: Since it can not be clear, I use the interpretation of the case.

I want all the application configurations to be templates and committed by developers and I want to give them an automatic way to fill those templates on those local machines (laptops) without using puppet. Additional benefits are actually the validity of the templates before submitting them.

I'm not sure why you want it to be done directly with Hierra data, but this is ERB And implementing with yaml ruby ​​libs will be easy. Something like this (SUUO-code): 

  Class Arbiter requires' Erb '' yaml attr_accessor: output_path ,: yaml_path def initialize (template, command) @output =: output_path @ Data =: yaml_ path ..... enddef render () ERB.new (@template) .rlt (binding) and deaf safe file. Open (file, "W +"). F | F.write (render) end end def parse_yaml (@data) File.open (@data, ... # Parsing some stuff, add them to local {} and end

, You can make an example of this class like: 

  newTemplate = Erbwritter.new (/ path / to / output, / path / to / yaml) newTemplate.save (file.join (Dir.pwd, again, it's basically psudo code and will not work out of the box, but it's very close. 
 
 You can read more about the ERB class. .

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
