Comptime Improvements

[Rune-Magic]

adds:

• Console.Write[Line] to comptime
• Environment.[G|S]etVariable to comptime
• make Compiler.Options.* eval to their enum type instead of to int32
• add Console.RunShellCommand

[Rune-Magic]

btw something like Console.RunShellCommand is neccersary because currently the only way to replicate its functionality is: (which doesn't run at comptime)

// I tried for an hour and was not able to get anything working :(

not sure if this is the best exposure of such a feature though

[bfiete]

And what about what I had mentioned earlier - write out a script/batch file and then run it in prebuild?

[bfiete]

RunShellCommand is not a feature I am prepared to add at the moment, as I had previously mentioned. It goes into a deeper feature or controlling the build process via code, which I had said I was not ready to do.

[Rune-Magic]

I mean you can already do this at comptime: (UseShellExecute doesn't work though)

let startInfo = scope ProcessStartInfo();
startInfo.SetFileNameAndArguments("<command>");
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.CreateNoWindow = true;

let proc = scope SpawnedProcess();
if (proc.Start(startInfo) case .Err)
    return;

let output = scope FileStream();
let sr = scope StreamReader(output);
proc.AttachStandardOutput(output);

while (!proc.HasExited)
{
	let str = sr.ReadToEnd(.. scope .());
	Console.Write(str);
}

it's just a more convinenient way of doing that

It's not the "executing things" that I object to, it's the "interacting with the build system via comptime" that I object to.

[Rune-Magic]

but RunShellCommand just runs a shell command, it doesn't run an ide command or a script manager command

let inst = app.DoRun("", StringView(cmd), app.mWorkspace.mDir, .None, null, null, .ShellCommand);

DoRun is the part of the "build system". This is "interacting with the build system via coptime". Why does everything with you have to be so argumentative?

[Rune-Magic]

I thought it only starts a process and streams it's stdout to the output window, but I can change the implementation if you like

I don't think you're hearing me, here. This feature is not happening.
