vim tabular only on the first match on the line?

Question

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     =           


        

Answer 1

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==
