Okay, my first attempt at an alias -- for those who simply want to add an event or task to your default Rainlendar calendar via the command line:
Save the following code as rainlendar.alias to your FindAndRunRobot\AliasGroups\MyCustom folder.
<?xml version="1.0" encoding="Legacy" ?>
<!-- This file defines aliases for use by the Find and Run Robot program (https://www.donationcoder.com/Software/Mouser/findrun/index.html). -->
<FarrAliasFile>
<FileFormatVersion>1</FileFormatVersion>
<AliasSetDescription>Rainlendar command line alias</AliasSetDescription>
<AliasEntry>
<AliasText>rld</AliasText>
<Score>1000</Score>
<Regex>^rld (.*)</Regex>
<Results>
<Result>Rainlendar $$1 | %PROGRAMFILES%\Rainlendar2\Rainlendar2.exe --add="$$1" </Result>
</Results>
</AliasEntry>
</FarrAliasFile>
Then in FARR, simply type rld and the event details (without quotes -- the alias adds the quote marks), e.g. type:
rld meeting tomorrow at 7pm
The alias will add the appointment to your Rainlendar default calendar. Hopefully. Works for me anyway, with the latest version of Rainlendar.
You'll need to change the location of the Rainlendar executable (%PROGRAMFILES%\Rainlendar2\Rainlendar2.exe in the alias) if you did not install Rainlendar to the default folder.
