Static capabilities

I don’t quite understand why this language server needs to register all of its capabilities dynamically:

:: --> jedi-language-server initialize(1): {'rootPath': '/home/raoul/.config/sublime-text-3/Packages/LSP', 'capabilities': {'experimental': {}, 'workspace': {'executeCommand': {}, 'didChangeConfiguration': {}, 'configuration': True, 'symbol': {'dynamicRegistration': True, 'symbolKind': {'valueSet': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26]}}, 'applyEdit': True, 'workspaceFolders': True}, 'textDocument': {'typeDefinition': {'dynamicRegistration': True, 'linkSupport': True}, 'codeAction': {'dynamicRegistration': True, 'codeActionLiteralSupport': {'codeActionKind': {'valueSet': []}}}, 'implementation': {'dynamicRegistration': True, 'linkSupport': True}, 'rename': {'dynamicRegistration': True}, 'definition': {'dynamicRegistration': True, 'linkSupport': True}, 'completion': {'dynamicRegistration': True, 'completionItem': {'snippetSupport': True}, 'completionItemKind': {'valueSet': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]}}, 'hover': {'dynamicRegistration': True, 'contentFormat': ['markdown', 'plaintext']}, 'signatureHelp': {'dynamicRegistration': True, 'signatureInformation': {'parameterInformation': {'labelOffsetSupport': True}, 'documentationFormat': ['markdown', 'plaintext']}}, 'colorProvider': {'dynamicRegistration': True}, 'publishDiagnostics': {'relatedInformation': True}, 'formatting': {'dynamicRegistration': True}, 'rangeFormatting': {'dynamicRegistration': True}, 'references': {'dynamicRegistration': True}, 'declaration': {'dynamicRegistration': True, 'linkSupport': True}, 'documentSymbol': {'dynamicRegistration': True, 'symbolKind': {'valueSet': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26]}}, 'documentHighlight': {'dynamicRegistration': True}, 'synchronization': {'willSaveWaitUntil': True, 'dynamicRegistration': True, 'willSave': True, 'didSave': True}}}, 'initializationOptions': {}, 'processId': 7057, 'workspaceFolders': [{'name': 'LSP', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP'}, {'name': 'LSP-eslint', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-eslint'}, {'name': 'metals-sublime', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/metals-sublime'}, {'name': 'lsp_utils', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/lsp_utils'}, {'name': 'LSP-json', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-json'}, {'name': 'UnitTesting', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/UnitTesting'}, {'name': 'LSP-vue', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-vue'}, {'name': 'LSP-css', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-css'}, {'name': 'LSP-html', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-html'}, {'name': 'LSP-intelephense', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-intelephense'}, {'name': 'LSP-typescript', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-typescript'}, {'name': 'LSP-elm', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP-elm'}, {'name': 'User', 'uri': 'file:///home/raoul/.config/sublime-text-3/Packages/User'}, {'name': 'tonic', 'uri': 'file:///home/raoul/Documents/Programming/tonic'}], 'rootUri': 'file:///home/raoul/.config/sublime-text-3/Packages/LSP', 'clientInfo': {'name': 'Sublime Text LSP'}}

Wouldn’t it be easier to put all this stuff in the initialize response?

"triggerCharacters": [
        "(",
        ",",
        ")"
      ]

The ) should not be a trigger char for signatureHelp. Means that if the user is done typing the args of a function and types the ) character, the editor requests textDocument/signatureHelp, and then you won’t be in a function signature context.

Yes, it’s working great for me now. Thanks for fixing this! I’ll try to create a PR in lsp-mode for emacs mentioning the server and adding the configurations.
