Add Scriptcs plugins support #229

laedit · 2015-03-29T13:04:14Z

Thanks to @vikingcode and @glennblock this PR allow Pretzel to have plugins as easily as to create a *.csx file in the _plugins folder.

But like @vikingcode has already said for some parts:

the projects are now upgraded to .NET 4.5
the total size of all dlls / exes is now about 13 mo (we can gain some size if we make a release for Windows (Roslyin) and another for Linux (Mono.Cecil) but I don't know if it worth it)
the merging is no longer supported, ILMerge and ILRepack explodes over a StackOverflowException. I haven't tried Fody.Costura but as stated on Pretzel on Mono #215 it doesn't seems to work for Mono, so between that and the total size of files, I think we should just embrace all the little dlls and stop the merging.

@shiftkey, @JakeGinnivan your thoughts?

glennblock · 2015-03-29T16:44:22Z

Why not have it be an opt-in add on package like Pretzel.ScriptCs. Is that
not possible?

Like always you give great advice, I will try that.

glennblock · 2015-03-29T19:45:26Z

@laedit not always, but at least some of the time :-)

It would seem based on what I know about this, that it should be possible to keep the scriptcs dependency out of Pretzel. Maybe allow passing in a catalog, which means just the MEF dependency is sufficient, or have a non-MEF specific plugin interface.

glennblock · 2015-03-29T19:55:27Z

src/Pretzel/Program.cs

@@ -102,6 +103,7 @@ private void LoadPlugins(string[] commandArgs)
                if (Directory.Exists(pluginsPath))
                {

Instead of hardcoding the dependency on scriptcs, you could find the catalog and dynamically load it. There's a host of diff strategies you could use to do this. One could be checking if the assembly exists, and if it does you dynamically load it and instantiate yourself via reflection. You could move ScriptcsCatalogOptions to a separate Pretzel.ScriptCs.Contracts package so that Pretzel and the Pretzel.ScriptCs package can reference it, this way Pretzel can still construct and pass in the options easily.

Since we already use MEF both for internals and plugins I was thinking to use it again, like loading the Pretzel.ScriptCs if exists and include it in the main catalog. Don't know if the DirectoryCatalog with a search pattern likePretzel.ScriptCs.dll will do the trick or if it's better to check and load it manually.
The Pretzel.ScriptCs.Contracts is a great idea, I will keep it in mind thanks.

That would actually be quite cool, grab the ScriptCs plugin then ScriptCs extensibility just works.

I made a quick and dirty test, but I face the same problem:

if I merge all dlls including Pretzel.ScriptCs.Contracts there is a cast exception caused by the class used to transmit parameters to the ScriptCsCatalog: the runtime cannot convert the type from the merged Pretzel assembly to the original Pretzel.ScriptCs.Contracts assembly
if I try to not merge Pretzel.ScriptCs.Contracts, ILMerge throw an exception:
Unresolved assembly reference not allowed: Pretzel.ScriptCs.Contracts.. ILRepack goes to a stack overflow...

Did I miss something?
Or we abandon the merging?

glennblock · 2015-03-31T02:08:58Z

I wasn't suggesting Contracts is merged. Pretzel.ScriptCs.Contracts should
be in a package that Pretzel and Pretzel.ScriptCs both reference. I don't
see how that can work with ILMerge.

That's what I was trying to do in my second point: Pretzel.ScriptCs.Contracts isn't part of the Pretzel merge, but int that case ILMerge can't work.
Or at least I haven't figured out how to make it work.

glennblock · 2015-03-31T06:59:37Z

I know very little about ILMerge but can't be much help her.

If an ILMerged assembly must have all dependencies merged, then it sounds
like you won't be able to split out the catalog functionality.

glennblock · 2015-03-31T07:21:41Z

Thinking about this more I have an idea of how you can do this which won't require Pretzel to reference the shared contracts directly. A new assembly (say Pretzel.ScriptCs) will contain a ScriptCsCatalogFactory (the answer to all things!). The factory will manufacture a ScriptCsCatalog and return it casted as a ComposablePartCatalog. If Pretzel needs to pass in types and such it can do it via the factory. The factory only exposes primitive / framework types, so it can easily be invoked via reflection. Pretzel will dynamically look for the factory and load it and then invoke it to get the catalog.

The code will look something like this...

public static class ScriptCsCatalogFactory {
  public static ComposablePartCatalog Create(string[] scriptArgs, Type[] references)
  {
    var options = new ScriptCsCatalogOptions {...};
    return new ScriptCsCatalog(options);
}

distantcam · 2015-03-31T08:02:49Z

ScriptCs had issues whenever I tried folding it into another assembly. There's a few ScriptCs classes that need to be reworked, and then there was a showstopper in Roslyn that meant I couldn't continue. Having said that I was trying this on the version of ScriptCs that used the old version of Roslyn. I haven't tried it since the update.

glennblock · 2015-03-31T08:05:55Z

Scriptcs still relies on the old version of Roslyn on Windows. You can
install the ScriptCs.Rosyln.Engines module to try the newer Roslyn.

Praise to @glennblock and shame on me. Following your comment I was so focused on the idea of using a Pretzel.ScriptCs.Contracts assembly to pass parameters that I haven't realized that it was the problem and wasn't really needed. Sorry for the fuss.

Just for testing purpose I tried to merge the Pretzel.ScriptCs and all his references (ScriptCs + Engine.Roslyn) but ILMerge still goes to a stack overflow.

And clean program parameters

laedit · 2015-04-21T04:56:09Z

Thanks to the recommendations of @ferventcoder, Pretzel will install itself in "C:\tools\Pretzel" (BinRoot or soon ToolsRoot in Chocolatey world) and so does Pretzel.ScriptCs.
@JakeGinnivan, @shiftkey are you ok with that?
