Last week I reinstalled Ubuntu 18.04 LTS on my laptop. During my last installation of ubuntu (also 18.04) I learned vim and used it in combination with the latex-suite. However on this new installation the <alt-I>
function does not work.
The <alt>
key works fine, for example with <alt-L>
and <alt-C>
, but when I use <alt-I>
I get é in both gVim and vi in the gnome terminal.
I reused a part of my .vimrc of my previous installation. From what I understood, this is the part that handles the alt-key mapping:
let c='a'
while c <= 'z'
exec "set <A-".c.">=\e".c
exec "imap \e".c." <A-".c.">"
let c = nr2char(1+char2nr(c))
endw
set timeout ttimeoutlen=50
(I think that I found this here: https://tex.stackexchange.com/questions/130389/vim-latex-suite-alt-macro-not-working but I am not sure since this is from my old .vimrc file, from my old installation.)
Because the alt-key works (for the other key combinations), I expect that it is some other setting.
Vim-latex is installed using Vundle. I tried to put this line:let g:Tex_AdvancedMath = 1
in ~/.vim/bundle/LaTeX-Suite-aka-Vim-LaTeX/ftplugin/tex_latexSuite.vim
. I tried both methods:
" LaTeX filetype
" Language: LaTeX (ft=tex)
" Maintainer: Srinath Avadhanula
" Email: [email protected]
if !exists('s:initLatexSuite')
let s:initLatexSuite = 1
exec 'so '.expand('<sfile>:p:h').'/latex-suite/main.vim'
let g:Tex_AdvancedMath = 1
silent! do LatexSuite User LatexSuiteInitPost
endif
silent! do LatexSuite User LatexSuiteFileType
and:
" LaTeX filetype
" Language: LaTeX (ft=tex)
" Maintainer: Srinath Avadhanula
" Email: [email protected]
if !exists('s:initLatexSuite')
let s:initLatexSuite = 1
exec 'so '.expand('<sfile>:p:h').'/latex-suite/main.vim'
silent! do LatexSuite User LatexSuiteInitPost
endif
silent! do LatexSuite User LatexSuiteFileType
let g:Tex_AdvancedMath = 1
(The difference between both methods is that either the let g:Tex_AdvancedMath = 1
is inside or outside the if statement).
Nothing worked so far. I did not had any trouble with the <alt>
-key, like that it is linked to the menu in GVim for example.
To be complete, this is my .vimrc file:

let c = nr2char(1+char2nr(c))
endw
set timeout ttimeoutlen=50
" Use a blinking upright bar cursor in Insert mode, a blinking block in normal

let &t_SI = "\<Esc>[5 q"

endif
if exists('$TMUX')
let &t_EI = "\<Esc>Ptmux;\<Esc>\<Esc>]50;CursorShape=0\x7\<Esc>\\"
let &t_SI = "\<Esc>Ptmux;\<Esc>\<Esc>]50;CursorShape=1\x7\<Esc>\\"
endif
edit
I disabled my .vimrc, by renaming .vimrc → .vimrc_backup. Now the plugins are disabled, but I é is still the result from clicking <alt-i>
in GVim, but not in the terminal.
<alt-i>
andé
are the same thing for gvim (I can't tell for Vim as I've given up on it because of alt key). There is an old issue in vim-latex where French users cannot properly typeé
. Because of that, there is a FAQ entry in vim-latex that explains how to avoid mapping<alt-i>
. Could it be that the trick is activated in your configuration, or that may be vim-latex finally gave up onalt-i
? vim-latex.sourceforge.net/faq.shtml#faq-e-acute<alt-i>
to tex_InsertItemOnThisLine. This worked, but now that text is shown when I used<alt-i>
, and I expect that some function should be called? Another problem is that most guides talk about tex.vim file, but I do not have that file. Is it possible that a Vundle installation is not the correct way to install the latex-suite?
