Correct way to configure texcompile in Linux

[CarlosGrohmann]

Hi,

I've been trying to get texcompile to work on Linux, but without success. I found an issue at the Lite-XL repo, but they only discuss Windows.

I have this in my usersettings.lua:

    ["plugins"] = {
      ["texcompile"] = {
        ["latex_command"] = "latexmk -c -lualatex",
        ["view_command"] = "evince"

But I cant get it to compile much less to visualize the pdf.

Any help appreciated.

Hello,

I've modified the current version of the plugin as follows to make it work (on Linux) and to add the command for BibTeX execution. Hope this may be helpful.

-- mod-version:3
local core = require "core"
local config = require "core.config"
local command = require "core.command"
local common = require "core.common"
local console = require "plugins.console"
local keymap = require "core.keymap"

-- This plugin requires the console plugin to work. It can be found at:
--
-- https://github.com/pragtical/console
--
-- Before using this plugin add in your user's config file something like:
--
-- config.plugins.texcompile = {
--   latex_command = "lualatex",
--   bibtex_command = "biber",
--   view_command = "evince",
-- }
--
-- as long as the commands are in your PATH.
--
-- Options can be passed as part of the command for example like in:
--
-- latex_command = "latex -pdf -pdflatex -c".
-- or
-- latex_command = "lualatex -synctex=1 -interaction=nonstopmode"
--
-- On Windows, if the commands are not in your PATH, you may use the full path
-- of the executable like, for example:
--
-- config.plugins.texcompile = {
--   latex_command = [[C:\miktex\miktex\bin\x64\pdflatex.exe]],
--   view_command = [[C:\Program^ Files\SumatraPDF\SumatraPDF.exe]],
-- }
--
-- Note that in the example we have used "^ " for spaces that appear in the path.
-- It is required on Windows for path or file names that contains space characters.

config.plugins.texcompile = common.merge({
  enabled = true,
  latex_command = "",
  view_command = "",
  bibtex_command = "",

  -- The config specification used by the settings gui
