How to configure a file watcher to automatically run code generator

Using AssetStore version of Entitas (w/Jenny)

In JetBrains Rider

Using the Jenny-Server

Create a custom Scope

Go to Settings -> Appearance & Behavior -> Scopes
Create a new scope
- Name: Changed component files
- Pattern: file[riderModule]:Assets/App/Features//*Component*.cs

All my components are either in a SomeComponent.cs file, or in SomeFeatureComponents.cs when I'm building a feature before I cleanup the code.

Create a file watcher

Go to Settings -> Tools -> File Watchers
Create a new file watcher
- name: Watch for component change
- File Type: C#
- Scope: Changed component files
- Program: $ProjectFileDir$\Jenny\Jenny.exe
- Arguments: client gen
- Working Directory: $ProjectFileDir$
- Advanced options: I enabled only Trigger watcher on external changes
- Show console: On Error

Auto Jenny-Server launch (Windows)

Don't want to have to manually start the jenny server manually?

Create a file "Jenny-Client-Gen.bat" in the project root

@echo off
pushd %~dp0

tasklist /FI "IMAGENAME eq Jenny.exe" 2>NUL | find /I /N "Jenny.exe"
if "%ERRORLEVEL%" NEQ "0" (
  START CMD /K CALL "Jenny-Server.bat"
)

.\Jenny\Jenny.exe client gen
popd

Update the "Program" field of the file watcher to run this batch file instead of Jenny.exe and remove the arguments.

It will check if Jenny is running and if not, start it in a new console window that will stay opened.

Auto Jenny-Server launch (Mac)

Create a file "Jenny-Client-Gen.txt” in the project root

#!/bin/bash
dir="$(cd $(dirname ${BASH_SOURCE[0]}) && pwd)"
cd $dir
ps ax | grep -v grep | grep "Jenny.exe server"
if [[ $? -ne 0 ]]; then
osascript -e "tell application \"Terminal\" to do script \"cd $dir; ./Jenny-Server;\""
sleep 3
fi
mono ./Jenny/Jenny.exe client gen

Don't forget to 'chmod +x (path to the file)/Jenny-Client-Gen.txt' to make it executable.

Update the "Program" field of the file watcher to run this file instead of Jenny.exe and remove the arguments.

It will check if Jenny is running and if not, start it in a new terminal window that will stay opened.
