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.
<alt> key works fine, for example with
<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: firstname.lastname@example.org 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
" LaTeX filetype " Language: LaTeX (ft=tex) " Maintainer: Srinath Avadhanula " Email: email@example.com 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:
set nocompatible " be iMproved, required filetype off " required " set the runtime path to include Vundle and initialize set rtp+=~/.vim/bundle/Vundle.vim call vundle#begin() " alternatively, pass a path where Vundle should install plugins "call vundle#begin('~/some/path/here') " let Vundle manage Vundle, required Plugin 'VundleVim/Vundle.vim' Plugin 'LaTeX-Suite-aka-Vim-LaTeX' Plugin 'junegunn/goyo.vim' Plugin 'junegunn/limelight.vim' Plugin 'Valloric/YouCompleteMe' Plugin 'scrooloose/nerdtree' Plugin 'tmhedberg/SimpylFold' "fold Plugin 'vim-syntastic/syntastic' " All of your Plugins must be added before the following line call vundle#end() " required filetype plugin indent on " required set relativenumber syntax on set showmatch set ruler set smarttab set shiftwidth=4 set tabstop=4 set expandtab set grepprg=grep\ -nH\ $* filetype indent on let g:tex_flavor='latex' let g:Tex_DefaultTargetFormat='pdf' map <f2> :w<cr><leader>ll "set spell spelllang=en_us set spell spelllang=en let c='a' while c <= 'z' exec "set <A-".c.">=\e".c exec "imap \e".c." <A-".c.">" let c = nr2char(1+char2nr(c)) endw set timeout ttimeoutlen=50 " Use a blinking upright bar cursor in Insert mode, a blinking block in normal if &term == 'xterm-256color' || &term == 'screen-256color' let &t_SI = "\<Esc>[5 q" let &t_EI = "\<Esc>[1 q" endif if exists('$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
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.
éare 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 type
é. 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 on
<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?
