extension cashes on Debian aarch64 with syntaxDiagnosticsForFile is not iterable

[drue]

On Debain Sid, Thinkpad X13s (Snapdragon 8cx / aarch64). I didn't have any trouble building the extension using the instructions in CONTRIBUTING.md , Dune and Ocaml seem to be working fine, but the results were the same when loading the generated .vsix directly.

/home/drue/.vscode-oss/extensions/chenglou92.rescript-vscode-1.18.0/server/out/server.js:665
            diagnostics: [...syntaxDiagnosticsForFile, ...compilerDiagnosticsForFile],

I should say that I got the same result with a fresh checkout of rescript-proect-template and a fresh install of the extension from the marketplace.

It is akin to #787
rescript-vscode doesn't pack analyzer binary for aarch64 linux

[drue]

Thanks for the tip! I got it working. For anyone else wanting to use the Rescript VSCode Extension on Linux ARM64/AARCH64 before it is officially supported, I used the following workaround:

1. install opam, dune, and cppo (was packaged in Ubuntu)
2. cd into the analysis directory in the extension source and "make" to build rescript-editor-analysis.exe binary
3. download a recent version of the extension from GitHub releases, version >= 1.20
4. open the .vsix file in a ZIP archive editor and copy the rescript-editor-analysis.exe binary into a new directory "linuxarm64" inside the existing "extension/server/analysis_binaries" directory
5. once you have put the analysis binary inside the vsix in extension/server/analysis_binaries/linuxarm64/rescript-editor-analysis.exe install the visx file into vs code by going into the extensions pane , clicking the ellipses menu, and choosing "Install from VSIX..."

happy hacking!

Is there an issue open for official support on Linux aarch64 platform? I still get this error in rescript-vscode-1.36.0.

P.S. Sorry for leaving a comment here, I just want to make sure that I don't file a duplicate issue.

There was indeed a (closed) issue which I reopened again now: #551
