Setting up a local LanguageTool server for Windows

If YouShouldSpellcheck.Analyzer should use LanguageTool for the analysis, it should always be executed against a local installation of the LanguageTool server, so that traffic on https://languagetool.org is avoided!

HTTP Server

LanguageTool gives a quick overview how it can be run as an HTTP server. But ideally, it should run as a service, so that it doesn't need a logged-on user and is automatically started after a restart of the machine.

To run LanguageTool as a Windows Service, winsw: Windows service wrapper can be used. It's README.md provides a nice and short Usage section. The XML configuration file could look something like this (it's just a suggestion of course):

<!--
<configuration>  
  <!-- ID of the service. It should be unique accross the Windows system-->
  <id>languagetool</id>
  <!-- Display name of the service -->
  <name>LanguageTool (powered by WinSW)</name>
  <!-- Service description -->
  <description>Local LanguageTool proofreading service</description>
  
  <!-- Path to the executable, which should be started -->
  <executable>C:\tools\LanguageTool-4.1\run.bat</executable>

  <!--
    OPTION: serviceaccount
    Defines account, under which the service should run.
  -->
  <serviceaccount>
    <domain>domainname</domain>
    <user>username</user>
    <password>secretpassword</password>
    <allowservicelogon>true</allowservicelogon>
  </serviceaccount>
</configuration>
