Add support for Go libraries

[Clement-Jean]

Starting the conversation on adding support for Go libraries (#5242).

@partouf Is this the set of files that I need to be working on? Am I missing something? Also, is there any way to test what I'm doing? either manually or automatically

[partouf]

Yes, these are the ones

To test you would need to:

• mkdir -p /opt/compiler-explorer if you hadn't already
• make ce
• bin/ce_install install 'go 1.22.1 to install GO 1.22.1 at the path that is expected
• bin/ce_install list go/protobuf which should show protobuf as an installable item (doesn't do anything but check configuration)
• bin/ce_install install go/protobuf (which will fail in this case, but should eventually work and probably do "nothing")
• bin/ce_install build --buildfor gl1221 go/protobuf (which will fail in this case, but should eventually work)

[partouf]

the important part here is probably

infra/bin/lib/library_builder.py

Line 122 in ea29967

[self.compilerprops, self.libraryprops] = get_properties_compilers_and_libraries(self.language, self.logger)

which will give you information about the compilers that are available

[partouf]

Also don't forget to add a case here:

infra/bin/lib/installable/installable.py

Line 265 in ea29967

elif self.build_config.build_type == "cargo":

You can check for self.build_config.type == "golib" instead of self.build_config.build_type.. but if that gives you trouble, maybe add a build_type to the lib entry at libraries.yaml and match with that.

Then instantiate and call the GoLibraryBuilder

[partouf]

You can use make static-checks to lint your code. There's also a make test, but it's probably not super useful here.

• bin/ce_install install 'go 1.22.1

is there a way to download the ARM64 version? It downloads the AMD64 by default

edit

I found the url in ./bin/yaml/go.yaml, I'll modify it locally

[partouf]

• bin/ce_install install 'go 1.22.1

is there a way to download the ARM64 version? It downloads the AMD64 by default

Ah.. not by default, but you can hack in this file https://github.com/compiler-explorer/infra/blob/main/bin/yaml/go.yaml#L6 and change the URL from amd64 to arm64

@partouf I made a little bit of progress but I'm still not sure I totally understand the difference between the library builder and the installable. As of right now, I'm able to install a library in /opt/compiler-explorer/libs/golibs.
