Latex editing in vim: how to change text in math mode

Question

I am using vim-latexsuite to edit a latex file. The text is from a google document and there are many mathematical symbols not written in mathematical mode.

I need to add $ before and after each character. But it hurts. (Search / Replace does not work because some equation templates are complex.)

Is there a way that allows you to visually select characters or equestions with Ctrl-V in visual mode, after pressing a key, $ can be automatically added before and after visual selection?

Answer 1

I don't think there is a standard command for this, but you can use the surround.vim plugin to do this:

csW$ command to surround the current text $

Answer 2

You can record a macro to do this.

With a visual selection, do the following:

q q - write macro to q register

c - change the content of the visual highlight

$ $ Esc - insert $$

P - paste the source text between $ s (pay attention to its capital P)

q - stop macro recording

From now on, you can make your visual choice and simply run @ q .

Answer 3

Actually there is a standard command for the built-in vim-latexsuite. See vim-latex docs for macros here.

 In addition the visual mode macros are provided: `( encloses selection in \left( and \right) `[ encloses selection in \left[ and \right] `{ encloses selection in \left\{ and \right\} `$ encloses selection in $$ or \[ \] depending on characterwise or linewise selection
