vim表格只在第一个匹配就行了？ [英] vim tabular only on the first match on the line?

问题描述

我想用tabular.vim插件格式化一些python代码。它是一个sqlalchemy声明类，看起来像这样：

$ $ $ $ $ $ c $ id $ db.Column（db.Integer，primary_key = True ）
status = db.Column（db.Integer，nullable = False，default = 3）
... etc ...

我想只能对齐列表中的第一个等号。

  id = db.Column（db.Integer，primary_key = True）
 status = db.Column（db。 Integer，nullable = False，default = 3）
 ... etc ... 
  

只是一个普通的

 ：Tabularize / = 
  

似乎可以配合一切，一切都变得疯狂。

非常感谢！ 命令：

 ：Tabularize / ^ [^ =] * \zs = 
  

该模式只与第一个 = 匹配。

您可以将这两行添加到〜/ .vim / after / plugin / TabularMaps.vim

  AddTabularPattern 1 = / ^ [^ =] * \ zs = 
 AddTabularPattern 1 == / ^ [^ =] * \zs = / r0c0l0 
  

---

下一次运行：

 ：Tabularize 1 = 
  

如果您不需要 = 周围的空格，请运行：

 ：Tabularize 1 ==

I'm trying to format some python code with the tabular.vim plugin. It's currently a sqlalchemy declarative class, and looks something like this:

id     =  db.Column(db.Integer, primary_key=True)
status    =  db.Column(db.Integer, nullable=False, default=3)
...etc...

I'd like to be able to align only the very first equals sign in the list.

id     =  db.Column(db.Integer, primary_key=True)
status =  db.Column(db.Integer, nullable=False, default=3)
...etc...

Just a regular

: Tabularize /=

seems to match everything, and everything goes crazy.

Thanks very much in advance!

解决方案

You can use this command:

:Tabularize /^[^=]*\zs=

The pattern only matches the first =.

---

You can add these two line to ~/.vim/after/plugin/TabularMaps.vim

AddTabularPattern 1=    /^[^=]*\zs=
AddTabularPattern 1==   /^[^=]*\zs=/r0c0l0

---

Next time, simply run:

:Tabularize 1=

If you don't need spaces around =, run this:

:Tabularize 1==
