If the pathname of your .tex file has a space the plugin fails to change the directory and then never gets to compiling the latex code. I've created a patch cless/neotex@2c3f26f and while that works it's probably not an ideal way to go about solving this issue.

I'm guessing vim passes the b:neotex_jobexe to the current shell, and I guess that means that how you escape your string depends heavily on your environment. Can the job be executed from python instead, using the subprocess api, or is there a special reason that it needs to be done from vimscript?

Could you please clarify how to use latexdiff? I installed your plugin and it works perfectly, exactly what I was looking for, however, I do not see how I can use the diff feature.

Hi there and thanks for creating and maintaining this plugin.

This is more of a feature request and less of an issue. I am hoping that neotex can also support certain TeX directives used in other editors and also vimtex. Here's an example of one of the directives:

% !TEX TS-program = lualatex

On editors / plugins that support this, they will automatically use the specified engine to compile their tex file. This is useful as one may use different engines to render their documents, while neotex currently only allows us to specify one engine. I tried setting the variable g:neotex_pdflatex_alternative while in a buffer that that did not work.

Here are two links for your reference about these directives: TeX SE and TeXWorks Docs

Supporting these directives will also resolve #8 through % !TeX root.

It would be great to have an option to compile bibtex references together with the whole document. In essence, a convention that the .bib file should be called the same as the .tex file would be sufficient I think.

As for now I post-compile .aux file with bibtex manually to make the whole thing working.

The general pipeline would be the following (source):

pdflatex <options> doc.tex &&
bibtex doc && # compiles doc.bib
pdflatex && <options> doc.tex
pdflatex <options> doc.tex

Though I think adding it as a permanent pipeline might break the compilation process in case there is no .bib file so it definitely should be an option.

I would try to tuckle the problem myself but I doubt I will succeed in a short term as I'm not a vim-script ninja.

P.S. Sadly, there is no feature-request label to add

Specifically deoplete. Completions don't show up until 5 seconds after typing when g:neotex_delay is set to 5000
Deoplete resumes normal behavior after calling :NeoTexOff

I need to render file with Chinese characters.

Things work fine when I'm in main.tex. But it issues errors when I move to other tex files, for example, files in sections/ subdirectory. So live preview doesn't work when I'm editing non-main files.

Error detected while processing function <SNR>50_latex_compile:
line    7:
E121: Undefined variable: b:neotex_jobexe

E15: Invalid expression: jobstart(['bash', '-c', b:neotex_jobexe], {'cwd': expand('%:p:h'), 'on_exit': function('s:job_exit')})

Hi,
i installed neotex via a package manager, and upon opening a .tex file i get the error:

Error detected while processing .../tex.vim:
line 20:
E117: Unknown function: _neotex_init

I looked through the code but unfortunately i know nothing about vimscript or how nvim handles the call to python.
Any help would be appreciated, thanks.

// edit: user error :x

Followed instructions to use vim-plug to install.

The NeoTex command is unavailable.

also have the following in init.vim:

let g:neotex_enabled = 2

Any help appreciated; would really like to get down to editing LaTeX in NeoVim.

First of all, thank you for making this plugin.

I would like to suggest you the implementation of synctex forward search. I've managed to get it working, but its far from good.

Here is my modified version of tex.vim:

if !get(g:, 'neotex_enabled', 1)
    finish
endif

if !exists('s:neotex_loaded')
    if !has('timers')
        echohl Error | echomsg 'NeoTex requires timers support' | echohl None
    endif
    if !has('nvim') && !has('job')
        echohl Error | echomsg 'NeoTex requires neovim or vim 8 with job support' | echohl None
    endif

    let s:neotex_buffer_tempname = tempname()
    if get(g:, 'neotex_latexdiff', 0)
        let s:neotex_preview_tempname = tempname()
    else
        let s:neotex_preview_tempname = s:neotex_buffer_tempname
    endif

    if !exists('g:neotex_delay')
        let g:neotex_delay = 1000
    endif

    augroup _neotex_
        au!
    augroup END

    command! NeoTexOn au! _neotex_ TextChanged,TextChangedI <buffer> call s:latex_compile_delayed()
    command! NeoTexOff au! _neotex_ TextChanged,TextChangedI <buffer>
    command! NeoTex call s:latex_compile(0)
    command! NeoTexFS call s:zathura_forward_search()

    let s:neotex_loaded = 1
endif

let b:neotex_jobexe=''

if get(g:, 'neotex_latexdiff', 0)
    let b:neotex_jobexe .= 'latexdiff '
    if exists('neotex_latexdiff_options')
        let b:neotex_jobexe .= g:neotex_latexdiff_options . ' '
    endif
    let b:neotex_jobexe .= fnameescape(expand('%:t')) . ' ' . s:neotex_buffer_tempname . ' > ' . s:neotex_preview_tempname . ' && '
endif

let b:neotex_jobexe .= get(g:, 'neotex_pdflatex_alternative', 'pdflatex') . ' -shell-escape -jobname=' . fnameescape(expand('%:t:r')) . ' -interaction=nonstopmode' . ' -synctex=1 '
if exists('neotex_pdflatex_add_options')
    let b:neotex_jobexe .= g:neotex_pdflatex_add_options . ' '
endif

let b:neotex_jobexe .= s:neotex_preview_tempname

if get(g:, 'neotex_enabled', 1) == 2
    au! _neotex_ TextChanged,TextChangedI <buffer> call s:latex_compile_delayed()
endif

function! s:job_exit(...)
    if exists('s:job')
        unlet s:job
    endif
endfunction

function! s:latex_compile(_)
    if exists('s:job')
        call s:latex_compile_delayed()
        return
    endif
    call writefile(getline(1, '$'), s:neotex_buffer_tempname)
    if has('nvim')
        let s:job = jobstart(['bash', '-c', b:neotex_jobexe], {'cwd': expand('%:p:h'), 'on_exit': function('s:job_exit')})
    else
        let s:job = job_start(['bash', '-c', b:neotex_jobexe], {'cwd': expand('%:p:h'), 'out_io':'null', 'exit_cb': function('s:job_exit')})
    endif
    if exists('s:timer')
        unlet s:timer
    endif
endfunction

function! s:latex_compile_delayed()
    if exists('s:timer')
        call timer_stop(s:timer)
    endif
    let s:timer = timer_start(g:neotex_delay, function('s:latex_compile'))
endfunction

function! s:zathura_forward_search()
    exec "silent !zathura --synctex-forward ".line(".").":".col(".").":".s:neotex_preview_tempname." ".fnameescape(expand('%:p:r')).".pdf &"
endfunction

There is one caveat. Since the tempfile changes, the function works only if NeoTex has compiled the file in the current session.

I can try to make this implementation if you wish, but I'm totally new to plugins. Let me know if you need something more.

Sorry for bad grammar.

How can I make NeoTexOn be on by default?

Maybe this is feature request?
Thanks

NeoTex doesn't work in neovim on windows (running a build from late march 2017).
Turns out, that the file path of the temporary file ( tempname() ) is not affected by
set shellslash
which should make paths use a forward slash instead of the windows backslash. A pathname such as C:\ble\rex.tex causes errors, while C:/ble/rex.tex is ok.

using
expand(tempname()) seems to be a solution, the following patch fixes this
