OS: Windows7 6.1.7601 + MSYS2 (3.1.4) + Pacman(5.2.1)
Vala: 0.48

  1. clone vls and compile it, then copy vala-language-server.exe to /mingw64/bin
    ----> vala-vscode can't load and start vls

  2. update client.ts to return valid path directly:

return "c:\\msys\\mingw64\\bin\\vala-language-server.exe";

----> then start the vls server, failed to load document:

vls: main.vala:207: Finished constructing
vls: main.vala:180: Got call! initialize
vls: main.vala:247: [initialize] root path is d:\Codelabs\GitHub\kangaroo

vls: main.vala:531: failed to find text document for `d:\Codelabs\GitHub\kangaroo\src\main.vala'
vls: main.vala:960: [textDocument/documentSymbol] file `file:///d%3A/Codelabs/GitHub/kangaroo/src/main.vala' not found
  1. update client.ts to return the path returned by which command
getLanguageServerPath(): string | null {
    let uri;
    if (window.activeTextEditor) {
        uri = window.activeTextEditor.document.uri;
    } else {
        uri = null;
    }
    // return workspace.getConfiguration('vls', uri).languageServerPath
    return which.sync('vala-language-server', { nothrow: true })
         || which.sync('gvls', { nothrow: true })
}

the vls server can start, then output the follow log:

vls: main.vala:207: Finished constructing
vls: main.vala:180: Got call! initialize
vls: main.vala:247: [initialize] root path is d:\Codelabs\GitHub\kangaroo
