Question

我一直遵循this，this，this，this和this在ST3中创建自己的模板。因此，当我创建一个新文件时，我会使用模板内容预加载该文件。我已经读过，应该用摘要来做。

我创建了一个文件，并尝试在新的snippet中应用view，但是什么也没有发生，我没有得到任何反馈（即使故意输入了错误的代码片段名称也没有）。我的片段在我的插件文件夹中：

C:\Users\...\AppData\Roaming\Sublime Text 3\Packages\MyPlugin\templ.sublime-snippet

我的多次尝试如下：

def on_done(...):
        ...
        open(path, 'a').close()
        new_view = self.window.open_file(path)

        # These seem to work, so the view seems valid
        print(new_view.file_name())
        print(new_view.line_height())

        # Attempt 1
        template = """<snippet>
        <content><![CDATA[
        Hello, \${1:this} is a \${2:snippet}.
        ]]></content>
        </snippet>
        """
        new_view.run_command("insert_snippet", {"contents": template})

        # Attempt 2: from the user folder. Nothing happens
        new_view.run_command("insert_snippet", { "name": "Packages/User/templ.sublime-snippet" })

        # Attempt 3: from current (?) folder just in case
        new_view.run_command("insert_snippet", {"name" : "templ.sublime-snippet"})

        # Attempt 4, from the actual plugin folder
        new_view.run_command("insert_snippet", {"name" : "Packages/MyPlugin/templ.sublime-snippet"})

        # Attempt 5, absolute directory
        new_view.run_command("insert_snippet", {"name" : "C:\\Users\\nerea\\AppData\\Roaming\\Sublime Text 3\\Packages\\MyPlugin\\templ.sublime-snippet"})

        # Attempt 6, to check if I mistook the path if I would get any error    
        new_view.run_command("insert_snippet", {"name" : "Packages/User/nonexisting.sublime-snippet"})

         # Attempt 7, nothing either
        new_view.run_command("insert_snippet", {"contents" : "<snippet><content><![CDATA[Hello, ${1:this} is a ${2:snippet}.]]></content></snippet>"})

        # This does nothing either. I supposed that should do something
        new_view.run_command("insert", "wawawiwa")

问题在于，执行insert_snippet命令时，视图尚未完成您指定的文件的加载。我建议尝试一下：

    new_view = self.window.open_file(path)
    def do_insert():
        if not new_view.is_loading():
            new_view.run_command("insert_snippet", { "name": "Packages/MyPlugin/templ.sublime-snippet" })
        sublime.set_timeout_async(do_insert, 10)
    do_insert()

如果您使用insert_snippet参数调用contents，则API仅期望代码段内容-即Hello, ${1:this} is a ${2:snippet}.而不是周围的XML。

请注意，摘要内容中的美元之前加反斜杠将使ST真正地对待美元，而不是划定制表符/编辑点。

代码段无法在ST3中静默插入
