Dear all, Based on Mike and Ted's examples, I'm trying my first "slightly intricate" (for me) mapping: I want a mapping to replace selected existing "(expression)" and "[expression]" in math mode by "\left(expression\right)" and "`\left[expression\right]", respecitvely. So far, I've come to the follownig visualmode macro, which, once I've selected an inner block with, say, vib, adds the \left and \right. I feel it is unelegant (not robust, not multiline, ugly <C-O>, etc etc), but I can't figure a nicer way with my limited vim knowledge... vmap jus "zdi\right<C-O>2b\left<C-O>p<Esc> Any feedback appreciated ! (no emergency, though) Thanks :) Julien |

Most sorry for polluting the list. I guess I should try my macro deeper before sending. The final (?) version is : vmap jus "zdi\right<C-O>b<C-O>2h\left<C-O>"zp<Esc> (my move commands to reach the left parenthesis were bogus) Sorry again ! If anybody has a good ref to recommand on using Vim macros sanely, I'd be glad :) Julien On Fri, Jan 9, 2009 at 2:03 PM, Julien Cornebise <jul...@gm...> wrote: > Correction : > vmap jus "zdi\right<C-O>2b\left<C-O>"zp<Esc> > > (forgot to call register z before pasting) > > Julien > > On Fri, Jan 9, 2009 at 2:00 PM, Julien Cornebise > <jul...@gm...> wrote: >> Dear all, >> >> Based on Mike and Ted's examples, I'm trying my first "slightly >> intricate" (for me) mapping: I want a mapping to replace selected >> existing "(expression)" and "[expression]" in math mode by >> "\left(expression\right)" and "`\left[expression\right]", >> respecitvely. >> >> So far, I've come to the follownig visualmode macro, which, once I've >> selected an inner block with, say, vib, adds the \left and \right.

First, don't knock yourself out. First, checkout
:help latex-suite
Then, while editing a TeX file, type:
((
You should find that suddenly a
\left( \right)<++>
appears and your cursor is in between the two of them. Type something
and then hit Cntrl+J. Now your cursor has jumped to the <++> had has
removed it.
Similarly, try typing:
[[
again, Cntrl+J to jump to the <++> placeholder.
These are IMAP mappings. You can build more of them yourself, but the
latex-suite includes lots of them. Within the mapping, things surrounded
by <+ and +> serve as placeholders. So you can build templates with
fields in them like <+name+>, <+date+>, etc., and then when you hit
CNTRL+J, Vim will take you to the next field that needs to be filled in.

> These are IMAP mappings. Thanks Ted, but I'm fully aware of the IMAP mappings :-) Sorry, I might not have been clear on the context : the latex file already exists, and is filled with unmatched parenthesis (my typographical choices -or lack of, thereof- were not always happy), some of them rightfully, other ... not. Hence I'm going through the formulae and changing the existing parentheses when needed. But where you're right is that I could maybe I can shorten my macro with these, leading to vmap jus ib"zdvab"_di((<Esc>"_2x"zP<C-j><Esc> directly applied in visual (i.e. used as vjus). Feels slightly cleaner. Only slightly. Anyway, that will do for what I have to do, I don't wan't to still more time. Thanks ! Julien |

Ok. Well, if it were me, I would highlight the section with the offending
(expressions)
(perhaps by pressing "v" and then moving to the end of the section) and
then issue
:s/(\([^)]\+\))/\\left(\1\\right)/g
(vim would automatically insert a '<,'> between the : and the s). You
could even make a quick mapping that did that for you.
That might be overkill (e.g., if you didn't want to fix *all* such
expressions), but it would work for a single selected expression too.
Additionally, if you weren't already aware, you can use % to jump from
the top of a LaTeX block (e.g., \begin{equation}) to the bottom
(\end{equation}) and back. That makes selecting large blocks quick.

Thanks. Still, that would indeed fix *all* the expressions, even
within the selection, not only the matched pair : No way to move from
:
( a + ( b + c ) )
to
\left( a + ( b + c ) \right)
Anyway, I'm nit-picking here :-) Thanks

Thank you ! I didn't know that !

I suppose that wouldn't work if the (expression) had a line break in the
middle of it... e.g.,
(expre
ssion)
Oh, well... Hopefully it was a useful example.

But, to be honest, it comes as a complete surprise to me that vib is multiline !! (I only checked as you mentionned the pb) Julien PS: Sorry Ted for the double post |
