Mac:

# macOS MacTex Install
$ brew cask set up mactex-no-gui
# Updating the applications
$ sudo tlmgr replace --self && sudo tlmgr replace --all

Installation used to be slightly rapid but it surely took a very long time to replace.
You might want to restart the terminal and take a look at if works:

$ latex --version
$ latexmk --version
$ platex --version

If it doesn’t paintings, then you want to upload a PATH to your ~/.zshrc or ~/.bash_profile:

export PATH="/Library/TeX/texbin/:$PATH"

Check it once more:

$ latex --version
pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020)
kpathsea edition 6.3.2
...
$ latexmk --version
Latexmk, John Collins, 29 September 2020. Version 4.70b
...
$ platex --version
e-pTeX 3.14159265-p3.8.3-191112-2.6 (utf8.euc) (TeX Live 2020)
kpathsea edition 6.3.2
...

Linux installation:

# Arch Linux Family
sudo pacman -S texlive-most
# For Ubuntu, you could desire a ppa:
sudo add-apt-repository ppa:jonathonf/texlive
sudo apt replace && sudo apt set up texlive-full
# Fedora
sudo dnf set up texlive-scheme-full

For Windows and different Linux OS please see this page.

This is how to use latexmk:

$ latexmk -silent textual content.tex

It will routinely replace the PDF dossier whilst you save a tex dossier. We can toughen it by editing the .latexmkrc dossier in your house listing.

$ contact ~/.latexmkrc

And upload the next.

#!/usr/bin/env perl# LaTeX
$latex = 'latex -synctex=1 -halt-on-error -file-line-error %O %S';
$max_repeat = 5;
# BibTeX
$bibtex = 'pbibtex %O %S';
$biber = 'biber --bblencoding=utf8 -u -U --output_safechars %O %S';
# index
$makeindex = 'mendex %O -o %D %S';
# DVI / PDF
$dvipdf = 'dvipdfmx %O -o %D %S';
$pdf_mode = 3;
# preview
$pvc_view_file_via_temporary = 0;
if ($^O eq 'linux') {
$dvi_previewer = "xdg-open %S";
$pdf_previewer = "xdg-open %S";
} elsif ($^O eq 'darwin') {
$dvi_previewer = "open %S";
$pdf_previewer = "open %S";
} else {
$dvi_previewer = "get started %S";
$pdf_previewer = "get started %S";
}
# blank up
$clean_full_ext = "%R.synctex.gz"
  • We use platex and dvipdfmx to convert a tex dossier to PDF.
  • latexmk -pv textual content.tex will show a PDF after the construct.
  • latexmk -p.c textual content.tex will replace the PDF dossier whilst you save the tex dossier. (You want to click on the PDF dossier to see the replace.)
  • You can forestall looking at for up to date information by ctrl+C.
VSCode extension LaTeX Workshop. Image by Author

After putting in LaTeX Workshop, you are going to see the TEX icon on the finish of the left sidebar.

The LaTeX Workshop extension creates a PDF on saving and you’ll view PDF in VS Code or a browser. It has formatting, intellisense completions, syntax-highlight, snippets and shortcuts options, and extra.

You can preview PDF by clicking View LaTeX PDF.

Open the settings.json by CMD/CTRL+SHIFT+P.

In the settings.json upload the followings:

{
// your different settings
// ...
// ...
// ---------- Language ----------
"[tex]": {
// Enable intellisence/fast tips
"editor.counsel.snippetsPreventQuickSuggestions": false,
// Indentation dimension
"editor.tabSize": 2
},
"[latex]": {
// Enable intellisence/fast tips
"editor.counsel.snippetsPreventQuickSuggestions": false,
// Indentation dimension
"editor.tabSize": 2
},
"[bibtex]": {
// Indentation dimension
"editor.tabSize": 2
},
// ---------- LaTeX Workshop ----------
// Enable command and setting finishing touch for used bundle
"latex-workshop.intellisense.bundle.enabled": true,
// goal dossier when deleting generated dossier
// Add "* .synctex.gz" to default price
"latex-workshop.latex.blank.fileTypes": [
"*.aux",
"*.bbl",
"*.blg",
"*.idx",
"*.ind",
"*.lof",
"*.lot",
"*.out",
"*.toc",
"*.acn",
"*.acr",
"*.alg",
"*.glg",
"*.glo",
"*.gls",
"*.ist",
"*.fls",
"*.log",
"*.fdb_latexmk",
"*.snm",
"*.nav",
"*.dvi",
"*.synctex.gz"
],
// sell off generated information to "out" listing
"latex-workshop.latex.outDir": "out",
// Build recipe
"latex-workshop.latex.recipes": [
{
"title": "latexmk",
"equipment": [
"latexmk"
]
},
],
// Parts used within the construct recipe
"latex-workshop.latex.equipment": [
{
"title": "latexmk",
"command": "latexmk",
"args": [
"-silent",
"-outdir=%OUTDIR%",
"%DOC%"
],
},
],
}

By default, intellisence/fast tips is probably not caused within a snippet. To allow them set:

"editor.counsel.snippetsPreventQuickSuggestions": false,

And make a selection latex.json (LaTeX) from the menu.

Let’s creates a elementary template. This is a pattern snippet you’ll upload:

{
"document": {
"prefix": "document",
"frame": [
"documentclass[${1:a4paper,11pt}]{${2:jsarticle}}",
"",
"",
"% Math",
"usepackage{amsmath,amsfonts}",
"usepackage{bm}",
"% symbol",
"usepackage[dvipdfmx]{graphicx}",
"usepackage[english]{babel}",
"$3",
"",
"start{file}",
"",
"name{$4}",
"creator{$5}",
"date{${6:nowadays}}",
"maketitle",
"",
"",
"$0",
"",
"",
"finish{file}"
],
"description": "LaTeX Sample Template"
}
}

You can upload multiple snippet:

{
"document": {
"prefix": "document",
"frame": [
...
"description": "LaTeX Sample Template"
},
"observe": {
"prefix": "observe",
"frame": [
...
"description": "Note layout"
},
"examination": {
"prefix": "examination",
"frame": [
...
"description": "Exam layout"
}
}

First set up the most recent Perl:

# For Mac
$ perl -v
This is perl 5, edition 18, subversion 2 (v5.18.2) constructed for darwin-thread-multi-2level
(with 2 registered patches, see perl -V for extra element)
Copyright 1987-2013, Larry Wall
...
$ brew set up perl

Open a brand new tab or restart your terminal and take a look at the edition put in:

$ perl -vThis is perl 5, edition 32, subversion 0 (v5.32.0) constructed for darwin-thread-multi-2levelCopyright 1987-2020, Larry Wall

You have to set up the next Perl applications:

$ cpancpan[1]>set up Log::Log4perl
Running set up for module 'Log::Log4perl'
...
cpan[2]>set up Log::Dispatch::File
Running set up for module 'Log::Dispatch::File'
...
cpan[3]>set up YAML::Tiny
Running set up for module 'YAML::Tiny'
...
cpan[4]>set up File::HomeDir
Running set up for module 'File::HomeDir'
...
cpan[5]>set up Unicode::GCString
Running set up for module 'Unicode::GCString'
...

When you replace and save the tex dossier, it’s going to replace the PDF dossier routinely.

Now you know the way to create a PDF out of your terminal the use of the latexmk. If you like GUI to convert LaTeX to PDF, the LaTeX Workshop is a useful gizmo. You can create your personal LaTeX snippet within the VSCode.

I am hoping you discovered this handy and with a bit of luck this may increasingly assist your productiveness when writing LaTeX paperwork.
