Add built-in compiler for Fallout2 .ssl files

[roginvs]

Description

This PR embeds a WebAssembly-compiled compile.exe into this extension. It is under options flag and it is disabled by default.

Having this compiler as WebAssembly build allow using this extension on non-intel processors, for example on Mac M1 or others.

Notes

Currently it uses compiled files from my repo but I will change it into sfall repo as soon as https://github.com/sfall-team/sslc/pull/14 is merged

Lots of any because I have not found a good typescript definitions for emscripten module (@types/emscripten have no .FS property on the instance)

I have not tested this on Windows but likely it will also work there

Interesting, I haven't considered M1. Does it not run wine? I thought there was some compatilibility layer.

[roginvs]

Actually I have no idea, but i had an impression that it was not possible to run x86/x64 apps on M1 Macbooks.

Anyways, even if it is possible then it still requires some setup. Having a embedded cross-platform compiler should be better user experience in my opinion. Maybe later we can enable it by default

CI fails on found npm access token: npm_i_save_dev_types_Slash but it also fails on almost empty PR https://github.com/roginvs/VScode-BGforge-MLS/pull/2

https://github.com/microsoft/vscode-vsce/issues/1153 maybe

[roginvs]

Yes, looks like it was a bug in vscode-vsce. Right now all checks passed.

I changed installation script, now it will check hash of downloaded release file. Just more security. With hash check it is not a big difference where this file was downloaded from

[burner1024]

So you aren't using an M1? What prompted you to work on this then?

[roginvs]

@burner1024 I was making a PR with test scripts into fallout2-ce. In the README file I added some instructions about how to compile https://github.com/fallout2-ce/fallout2-ce/pull/140/files#diff-7e0064f2b1902c3c7083e171e90a0a91df55a38157bf30de762952196392b179 but then I though that having an additional step of installing compile.exe can be annoying.

I am simple user, I want a button which makes everything for me. As user I want to install extension and to have a ready-to-use IDE.

Well, the simplest way for that would be to just bundle compile.exe, I guess. But having native cross-platform builds paves the way for future improvements, so that's cool too.

Let's see when the upstream PR gets merged.

[roginvs]

Looks like PR into sslc got stuck for a while. Let's hope it will be merged at some point.

I think there is no blockers right now for merging this PR. I tested it locally and it works for me. There is a hash of the package in package-lock.json so npm/pnpm will not allow to install something else which do not have the same hash

[burner1024]

I'll look it over soon.

I'd assign Copilot to review this PR if I had permission to add reviewers. :)

Copilot itself advised me to make that comment to request a review, apparently that didn't work :), so assigned it in GUI.

Updated to use sslc from https://github.com/sfall-team/sslc

[burner1024]

Looks like it has trouble working with symlinks. On my system, Fallout2_Restoration_Project/scripts_src/headers/sfall is a symlink to sfall headers. External compiler works with that, while built-in one doesn't. Also leaves cruft behind.

Linux build works fine too.

[roginvs]

@burner1024 Thanks, I will take a look. I have Linux and symlink too but it is relative symlink. I tested now with absolute symlink and I confirm that it needs fixing.

I will try to use NODERAWFS again, very likely it fails to find path because of absolute symlink and because host FS is mounted into subfolder.

About leftover *.tmp: it also happens on Linux build, probably because of https://github.com/sfall-team/sslc/blob/master/compile.c#L239 and https://github.com/sfall-team/sslc/blob/master/compile.c#L261 . I will take a look on this too

@burner1024

• Leftover .tmp files are fixed. Merged in my repo, waiting to be merged in sslc repo
• I changed filesystem back to NODERAWFS because we need to mount host FS into the root inside guest. Mounting host into sub-folder caused absolute symlinks to fail. Because NODERAWFS does not work good on multiple runs we have to spawn new process each time, similar to using compile.exe

[burner1024]

OK, merged and released, thanks.
