问题描述

我一直在关注这个这个这个这个这个在 ST3 中创建我自己的模板。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。我已经读过我应该用一个片段来做到这一点。

我创建了一个文件并尝试snippet在 new中应用 a view,但没有任何反应,我没有得到任何反馈(即使我故意输入了错误的片段名称)。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")

解决方案


问题是视图尚未完成加载您在执行insert_snippet命令时指定的文件。我建议试试这个:

    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insert_snippet使用contents参数调用,API 只需要片段内容 - 即Hello, ${1:this} is a ${2:snippet}.,而不是周围的 XML。

请注意,在片段内容中的美元之前有一个反斜杠将导致 ST 按字面意思对待美元,而不是描述制表符/编辑点。
