摘要中的Tab功能的ST3交换优先级（嵌套摘要） [英] ST3 swap priority of tab function within a snippet (nested snippets)

问题描述

发现自己经常调用一个代码段中的一个代码段，但是，当我去扩展嵌套代码段时，Tab键会将我移到第一个代码段的下一个条目或第一个代码段的末尾（此时，我必须将光标替换为第二个代码段的tab-trigger表达式的末尾，然后点击tab，这时第二个代码段将展开。

Find myself frequently invoking a snippet within a snippet, but of course when I go to expend the nested snippet, the tab key moves me to either the next entry of the first snippet or the end of the first snippet (at which point, I have to replace the cursor at the end of the tab-trigger expression for the 2nd snippet and hit tab, at which point the 2nd snippet is expanded).

例如。给定的片段 [内容A $ {1：A中的第一点和$ {2：A}中的第二点] ，并使用制表键触发 tabtrigA 和摘要 [内容B] ，并使用Tab键触发 tabtrigB

eg. given snippet [ content A ${1:First point in A} and ${2: Second point in A} ] with tab-trigger tabtrigA and snippet [ content B ] with tab-trigger tabtrigB

我希望能够执行以下操作：

I'd like to be able to do the following:

In [1]：

tabtrigA % Hit tab to expand snippet A

Out [1]：

 [ content **A First point in A** and ${2: Second point in A} ] % where everything between ** ** is highlighted

现在替换 * * ... ** 包含 tabtrigB

In [2]：

     [ content tabtrigB* and ${2: Second point in A} ] % where * marks location of cursor.

并点击 tab 会导致：

Out [2]：

 [ content [ content B ]* and ${2: Second point in A} ] % where * marks location of cursor

的位置，然后点击 tab 会再次跳到摘要A的第二个条目

and hitting tab again would then jump to second entry of snippet A

显然这很烦人：是否有可能切换 tab 的优先级分配，使其首先充当Tab触发，并且仅在没有Tab触发的情况下才跳转到下一个条目？

Obviously this is tiresome: is it possible to switch the priority assignment of tab so that it first acts as a tab-trigger and only jumps to next entry if there is no tab-trigger?

更新：截至2019年4月，仍然没有解决方案来触发摘要中的摘要。

Update: as of April 2019, still no solution for triggering a snippet within a snippet.

推荐答案

我认为Sublime不能从告诉 this 片段的next_field 片段的next_field。您只能询问它是否具有has_next_field。但是您可以采用以下解决方法：

I don't think sublime can tell this snippets' next_field from that snippet's next_field. You can only ask if it has_next_field, any. But you could go with workarounds:

1. 通过命令面板，为嵌套的片段提供描述。下面的代码段可以从面板中作为代码段调用：description_for_command_palette 。

1. Through command palette by giving your nested snippet a description. The snippet below will be callable from the palette as Snippet: description_for_command_palette.

<snippet>
<content><![CDATA[
[ content B ]
]]></content>
<description>description_for_command_palette</description>
</snippet>

1. 通过键盘绑定到代码段路径：

{ keys：[ ctrl + 0]， command： insert_snippet， args ：{名称：软件包/用户/您的snippet.sublime-snippet}}

1. 通过与匿名代码段的快捷键绑定：

{ keys：[ ctrl + 0]， command： insert_snippet， args：{ contents： [content B]}}

只需添加两个键绑定：

{ "keys": ["enter"], "command": "next_field", "context":
[
{ "key": "has_next_field", "operator": "equal", "operand": true }
]
},
{ "keys": ["tab"], "command": "insert_best_completion", "args": {"default": "\t", "exact": false}, "context":
[
{ "key": "has_next_field", "operator": "equal", "operand": true }
]
}
