EcmaScript 6 - 用于Eclipse验证错误的Tern IDE

问题描述

我正在使用Eclipse Mars与版本1.1.0（快照）上的Tern IDEfürES6支持。我在箭头函数和常量导出中得到验证错误，可以在这个截图中看到：

我通过这些描述，但是错误不会消失：

我不知道Tern插件真正支持什么，但根据 Tern应该支持箭头函数0.14。 github上的IDE页面只提及类，导入和承诺支持（这在我的眼中超出了基本的插件来支持ES6）。有没有人正在使用Eclipse（或多或少）完整的功能支持来开发ES6的ES6？我有点像独角兽...

解决方案

你的错误来自不支持ES6语法的JSDT验证器从tern）。

tern 1.1.0-SNAPSHOT提供对ES6的完成，超链接，验证但不是ES6验证的支持。短信是一种类型检查器验证器，而不是语法验证器。

要使用Eclipse IDE& tern.java，您必须：

• 禁用JSDT验证器。为此，您可以从.project中删除JSDT性质。或者安装（从未测试过）未发布的Eclipse JEE发行版，它提供一个关闭内部解析和验证的选项。请参阅




• 之后，您可以使用JSHint验证ES6，。要使JSHint正确验证ES6，需要启用esnext - 启用，否则ES6语法将被标记为错误。该选项位于放松选项下的项目properties\Tern\Validation\JSHint中。

I am using Eclipse Mars with the Tern IDE für ES6 support on version 1.1.0 (the snapshot). I get validation errors on arrow functions and const-exports as can be seen in this screenshot:

I worked through these descriptions but the errors won't vanish:https://github.com/angelozerr/tern.java/wiki/Tern-&-ECMAScript6-supporthttps://github.com/angelozerr/tern.java/wiki/Tern-Linter

I don't know however whats really supported by the Tern plugin, but according to the documentation on http://ternjs.net/ Tern should support arrow functions since 0.14. The IDE-page on github however only mentions class, import and promise support (which is beyond basic in my eyes for a plugin to support ES6).

Is there anyone who is developing ES6 with Eclipse with (more or less) full feature support? I kinda feel like a unicorn...

解决方案

Your error comes from JSDT Validator which doesn't support ES6 syntax (and not from tern).

tern 1.1.0-SNAPSHOT provides support for ES6 for completion, hyperlink, validation but not for ES6 validation. The linter https://github.com/angelozerr/tern.java/wiki/Tern-Linter is a type checker validator and not a syntax validator.

To validate ES6 with Eclipse IDE & tern.java, you must:

• disable JSDT Validator. For that you can remove the JSDT nature from your .project. Or install (never tested) the not released Eclipse JEE distribution which provides an option to turn off internal parsing and validation. See http://tools.jboss.org/documentation/whatsnew/jbosstools/4.3.0.Final.html#javascript-development-tools-improvements

• after that, you can use JSHint to validate ES6, with https://github.com/angelozerr/tern.java/wiki/Tern-Linter-JSHint. To enable JSHint to validate ES6 correctly it needs to get the "esnext"-option enabled otherwise ES6 syntax will be marked as errors. The option is found in the project properties\Tern\Validation\JSHint under "Relaxing options".
