In my constant quest to bring Castle MonoRail closer to Ruby on Rails development style, one of the thing that kept me from choosing MonoRail over Rails for fun and pleasure was the code-compile-refresh process. Because we’re working in the static compiled world, a usual scenario looks like this.
- Add or remove some code
- Compile from the IDE or run NAnt
- Restart the web server (under *nix XSP needs to be restarted to load the new assembly)
- Refresh the browser (and wait for the app to restart AR and all other services)
This is painful! Why can’t we just code and refresh like with scripting languages?
# Rebuilds the project periodically and restarts the web server on success import System import System.IO import System.Threading import System.Diagnostics SERVER_CMD = 'xsp2' SERVER_ARGUMENTS = '--root public' NANT_ARGUMENTS = 'build -nologo -q' PROJECT_ASSEMBLY = 'public/bin/MyBlog.dll' REBUILD_DELAY = 1000 #ms serverProcess as Process lastWriteTime as DateTime print "Starting runner process, hit CTRL+C to stop" while (true): buildProcess = shellp('nant', NANT_ARGUMENTS) buildProcess.WaitForExit() if buildProcess.ExitCode == 0: if FileInfo(PROJECT_ASSEMBLY).LastWriteTime > lastWriteTime: print "Project recompiled, restarting the server" if serverProcess != null: try: # Stops the server serverProcess.Kill() except e: pass serverProcess.WaitForExit() serverProcess = null serverProcess = shellp(SERVER_CMD, SERVER_ARGUMENTS) lastWriteTime = FileInfo(PROJECT_ASSEMBLY).LastWriteTime else: print buildProcess.StandardOutput.ReadToEnd() # Waits a couple of seconds Thread.CurrentThread.Sleep(REBUILD_DELAY)
If you can’t see what this is about…
The other thing that keep me from dropping Rails for MonoRail is C# extra verbose and lack of fun and style. But I can’t do nothing about that, except use Boo whenever I can.
Note that this script will soon be integrated in the Generator so when you generate a new MonoRail project, the server script while run something like this.
