有人在折腾tailwindcss server的吗？我正在尝试为lsp-bridge添加tailwind server的支持。

折腾思路:

  1. 研究lsp-mode下tailwind client的参数有哪些 根据我的提取，得到以下参数配置:
{
"name": "tailwindcss",
"languageId": "html",
"command": ["tailwindcss-language-server", "--stdio"],
"settings": {},
"capabilities": {},
"initializationOptions": {
  "configuration": {
    "tailwindCSS": {
      "emmetCompletions": false,
      "showPixelEquivalents": true,
      "rootFontSize": 16,
      "validate": true,
      "lint": {
        "invalidScreen": "error",
        "invalidVariant": "error",
        "invalidTailwindDirective": "error",
        "invalidApply": "error",
        "invalidConfigPath": "error",
        "cssConflict": "warning",
        "recommendedVariantOrder": "warning"
      },
      "experimental": {
        "classRegex": "",
        "configFile": "tailwind.config.js"
      },
      "classAttributes": ["class", "className", "ngClass"]
    }
  }
}
}

但是通过以上参数初始化服务器会得到如下结果:

--- Send (63379): initialize
{
   "id": 63379,
   "method": "initialize",
   "params": {
      "processId": 3254507,
      "rootPath": "/home/evanmeek/Documents/code/project/web/domeland-ui",
      "clientInfo": {
         "name": "emacs",
         "version": "GNU Emacs 28.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, cairo version 1.17.6)\n of 2022-04-28"
      },
      "rootUri": "file:///home/evanmeek/Documents/code/project/web/domeland-ui",
      "capabilities": {},
      "initializationOptions": {
         "configuration": {
            "tailwindCSS": {
               "emmetCompletions": false,
               "showPixelEquivalents": true,
               "rootFontSize": 16,
               "validate": true,
               "lint": {
                  "invalidScreen": "error",
                  "invalidVariant": "error",
                  "invalidTailwindDirective": "error",
                  "invalidApply": "error",
                  "invalidConfigPath": "error",
                  "cssConflict": "warning",
                  "recommendedVariantOrder": "warning"
               },
               "experimental": {
                  "classRegex": "",
                  "configFile": "tailwind.config.js"
               },
               "classAttributes": [
                  "class",
                  "className",
                  "ngClass"
               ]
            }
         }
      }
   },
   "jsonrpc": "2.0"
}

--- Recv message (error):
{
   "jsonrpc": "2.0",
   "id": 63379,
   "error": {
      "code": -32603,
      "message": "Request initialize failed with message: Cannot read properties of undefined (reading 'hover')"
   }
}

随后我通过阅读tailwind-server的源码进行了修改，但是目前不知道如何debug tailwindserver（如何看它的输出日志）。

有大佬知道的请@我，十分感谢！

591

有了tailwindcss server的日志我就可以更好的debug，否则瞎猜参数不知道得撞墙到猴年马月呀

592

看样子少传了一个 hover 属性呀。

593

是的，但是我补上后还是会有其他问题

594

所有就想着能不能debug到server的日志，这样就能仔细排查了

595

你用 ripgrep 去搜索源代码呢？ 就用 Request initialize failed with message ， 这样你可以看看服务器到底想要的是哪个key你没有？

596

rg搜索过，没有找到有关的字符串，看来可能是lsp自动处理的

但是我已经定位到初始化的那个函数了

597

我给配置加上这段:

"capabilities": {
         "textDocument": {
            "hover": {
               "dynamicRegistration": true
            }
         }
      },

可以做到不提示hover错误，但是会提示 “message”: “Request initialize failed with message: Cannot read properties of undefined (reading ‘dynamicRegistration’)”

可根据lsp协议文档，我已经设定了这个 dnyamicRegistration

598

尝试把textDocument/hover/dynamicRegistration设置为false解决了上面的问题

下面开始提示这个错误了:

--- Recv notification: window/logMessage
{
   "jsonrpc": "2.0",
   "method": "window/logMessage",
   "params": {
      "type": 1,
      "message": "Unhandled exception: Cannot read properties of undefined (reading 'files')\nTypeError: Cannot read properties of undefined (reading 'files')\n    at /usr/bin/tailwindcss-language-server:690:1862\n    at Generator.next (<anonymous>)\n    at i (/usr/bin/tailwindcss-language-server:2:1059)"
   }
}

从错误中可以看出直接给了代码出错的行数，可惜这个代码是被压缩过的.

不过我看了源码，可能还需要处理onCompletetion的错误，这个错误可能就是onCompletion出现的错误了

async init(): Promise<void> {
    if (this.initialized) return;

    this.initialized = true;

    // TODO
    let workspaceFolders: Array<ProjectConfig> =
      false &&
      Array.isArray(this.initializeParams.workspaceFolders) &&
      this.initializeParams.capabilities.workspace?.workspaceFolders
        ? this.initializeParams.workspaceFolders.map((el) => ({
            folder: getFileFsPath(el.uri),
          }))
        : this.initializeParams.rootPath
        ? [
            {
              folder: normalizeFileNameToFsPath(this.initializeParams.rootPath),
            },
          ]
        : [];

    if (workspaceFolders.length === 0) {
      console.error("No workspace folders found, not initializing.");
      return;
    }

    let configFileOrFiles = dlv(
      await connection.workspace.getConfiguration("tailwindCSS"),
      "experimental.configFile",
      null
    ) as Settings["tailwindCSS"]["experimental"]["configFile"];

    if (configFileOrFiles) {
      let base = workspaceFolders[0].folder;

      if (
        typeof configFileOrFiles !== "string" &&
        (!isObject(configFileOrFiles) ||
          !Object.entries(configFileOrFiles).every(([key, value]) => {
            if (typeof key !== "string") return false;
            if (Array.isArray(value)) {
              return value.every((item) => typeof item === "string");
            }
            return typeof value === "string";
          }))
      ) {
        console.error(
          "Invalid `experimental.configFile` configuration, not initializing."
        );
        return;
      }

      let configFiles =
        typeof configFileOrFiles === "string"
          ? { [configFileOrFiles]: "**" }
          : configFileOrFiles;

      workspaceFolders = Object.entries(configFiles).map(
        ([relativeConfigPath, relativeDocumentSelectorOrSelectors]) => {
          return {
            folder: base,
            configPath: path.join(base, relativeConfigPath),
            documentSelector: []
              .concat(relativeDocumentSelectorOrSelectors)
              .map((selector) => path.join(base, selector)),
          };
        }
      );
    }

    await Promise.all(
      workspaceFolders.map((projectConfig) =>
        this.addProject(projectConfig, this.initializeParams)
      )
    );

    this.setupLSPHandlers();

    if (
      this.initializeParams.capabilities.workspace?.didChangeWatchedFiles
        ?.dynamicRegistration
    ) {
      this.connection.onDidChangeWatchedFiles(({ changes }) => {
        for (let [, project] of this.projects) {
          project.onFileEvents(
            changes.map(({ uri, type }) => ({
              file: URI.parse(uri).fsPath,
              type,
            }))
          );
        }
      });
    }

    this.connection.onDidChangeConfiguration(async ({ settings }) => {
      for (let [, project] of this.projects) {
        project.onUpdateSettings(settings);
      }
    });

    this.connection.onShutdown(() => {
      this.dispose();
    });

    this.documentService.onDidChangeContent((change) => {
      this.getProject(change.document)?.provideDiagnostics(change.document);
    });
  }
```typescript
private setupLSPHandlers() {
    this.connection.onHover(this.onHover.bind(this));
    this.connection.onCompletion(this.onCompletion.bind(this));
    this.connection.onCompletionResolve(this.onCompletionResolve.bind(this));
    this.connection.onDocumentColor(this.onDocumentColor.bind(this));
    this.connection.onColorPresentation(this.onColorPresentation.bind(this));
    this.connection.onCodeAction(this.onCodeAction.bind(this));
  }

这个问题调了很久都没找到解决方法，但是我发现一个调试方法，只需要在源码内加上console.log(msg) 这个server会自动把log的信息以window/logMessage的形式返回，这样我就有一个简单的调试工具了

错误定位到addProject这一步了！果然还是log大法好

为什么查引用这里使用lsp-bridge-find-def ？

这是 bug 还是 feature

600

@zwPapEr 帮忙看看？

601

这个问题已经被 Add support textEdit by jadestrong · Pull Request #113 · manateelazycat/lsp-bridge · GitHub 修复了，你更新到最新版了吗？

602

eglot 能够处理这种情况吗？ 如果可以，能否帮忙对比一下 eglot 和 lsp-bridge 的日志？ 谢谢

604

更新了，看样子不是同一个问题，和现在 issue 里提的估计是同一个，主要是偶现，频率非常低，我写一天代码也就出现那么几次，等上班把 issue 里提到的那几个地方打上日志看下

605

好的，有日志就好修复，感谢反馈

606

本来今天想试一下pylance, 配置都加好了

{
  "name": "pylance",
  "languageId": "python",
  "command": ["pylance-language-server", "--stdio"],
  "settings": {
    "python.analysis.typeCheckingMode": "basic",
    "python.analysis.diagnosticMode": "openFilesOnly",
    "python.analysis.stubPath": "./typings",
    "python.analysis.autoSearchPaths": true,
    "python.analysis.extraPaths": [],
    "python.analysis.diagnosticSeverityOverrides": {},
    "python.analysis.useLibraryCodeForTypes": true,
    "python.analysis.autoImportCompletions": true,
    "python.analysis.completeFunctionParens": false
  }
}

pylance一启动就不让我们用呀：

大佬，elgot是正常的。 这个是eglot的操作，一样的操作下，lsp-bridge 和 eglot的日志附后； simplescreenrecorder-2022-05-21_11.47.06

lsp-bridge

eglot

非常感谢。

608

我推送了一个补丁

更新后尝试一下。

609

有可能是这个补丁的锅，我看看。

应该和 pyright.json 里面配置 stubPath 也有关系，我尝试 pyright --createstub scipy 并修改 stubPath 以后，还是不行的。

等以后看看其他人研究了。
