| title: "Gopls: Support for Go *.s assembly files" |
| --- |
| |
| Gopls has rudimentary support for LSP operations in Go assembly files. |
| |
| Go assembly files have a `.s` file name extension. LSP clients need to |
| be configured to recognize `.s` files as Go assembly files, since this |
| file name extension is also used for assembly files in other |
| languages. A good heuristic is that if a file named `*.s` belongs to a |
| directory containing at least one `*.go` file, then the `.s` file is |
| Go assembly, and its appropriate language server is gopls. |
| |
| Only Definition (`textDocument/definition`) requests are currently |
| supported. For example, a Definition request on the `sigpanic` |
| symbol in this file in GOROOT/src/runtime/asm.s: |
| |
| ```asm |
| JMP ·sigpanic<ABIInternal>(SB) |
| ``` |
| |
| returns the location of the function declaration in |
| GOROOT/src/runtime/signal_unix.go: |
| |
| ```go |
| //go:linkname sigpanic |
| func sigpanic() { |
| ``` |
| |
| See also issue https://go.dev/issue/71754, which tracks the development of LSP |
| features in Go assembly files. |
