Code Highlighter
Highlight code written in more than 160 languages.
After Dark uses a customized version of One Dark Syntax to produce print-friendly code highlighting for more than 160 languages.
ABNF, ANTLR, APL, ActionScript, ActionScript 3, Ada, Angular2, ApacheConf, AppleScript, Arduino, Awk, BNF, Ballerina, Base Makefile, Bash, Batchfile, BlitzBasic, Brainfuck, C, C#, C++, CFEngine3, CMake, COBOL, CSS, Cap'n Proto, Ceylon, ChaiScript, Cheetah, Clojure, CoffeeScript, Common Lisp, Coq, Crystal, Cython, DTD, Dart, Diff, Django/Jinja, Docker, EBNF, Elixir, Elm, EmacsLisp, Erlang, FSharp, Factor, Fish, Forth, Fortran, GAS, GDScript, GLSL, Genshi, Genshi HTML, Genshi Text, Gnuplot, Go, Go HTML Template, Go Text Template, Graphql, Groovy, HTML, HTTP, Handlebars, Haskell, Haxe, Hexdump, Hy, INI, Idris, Io, JSON, JSX, Java, JavaScript, Julia, Kotlin, LLVM, Lighttpd configuration file, Lua, Mako, Mason, Mathematica, Matlab, MiniZinc, Modula-2, MorrowindScript, MySQL, Myghty, NASM, Newspeak, Nginx configuration file, Nim, Nix, OCaml, Objective-C, Octave, Org Mode, PHP, PL/pgSQL, POVRay, PacmanConf, Perl, Pig, PkgConfig, PostScript, PostgreSQL SQL dialect, PowerShell, Prolog, Protocol Buffer, Puppet, Python, Python 3, QBasic, R, Racket, Ragel, Rexx, Ruby, Rust, SCSS, SPARQL, SQL, Sass, Scala, Scheme, Scilab, Smalltalk, Smarty, Snobol, Solidity, SquidConf, Swift, TASM, TOML, Tcl, Tcsh, TeX, Termcap, Terminfo, Terraform, Thrift, Transact-SQL, Turing, Turtle, Twig, TypeScript, TypoScript, TypoScriptCssData, TypoScriptHtmlData, VHDL, VimL, WDTE, XML, Xorg, YAML, cfstatement, markdown, reStructuredText, reg, systemverilog, verilog
To activate the highlighter indicate the highlighting language in a fenced code block within your markdown:
```go-html-template
<div class="alert {{ with .type }}alert-{{ . }}{{ end }}">
{{ .body }}
</div>
```
Resulting in the following highlighted code:
<div class="alert {{ with .type }}alert-{{ . }}{{ end }}">
{{ .body }}
</div>
Or use the highlight shortcode provided by Hugo:
{{< highlight python >}}
@app.on_message(Filters.private)
def hello(client, message):
message.reply_text("Hello {}".format(message.from_user.first_name))
{{< /highlight >}}
To add line numbers and highlighting:
5@app.on_message(Filters.private)
6def hello(client, message):
7 message.reply_text("Hello {}".format(message.from_user.first_name))Not feeling the colors? No problem. Use the hugo gen chromastyles command to
generate your own syntax.css stylesheet from the
style gallery and customize it using the general-purpose
Atom One Chroma syntax theme-roller.
And if you’re really enterprising why not create some executable ASCII art representing the name of the game you implemented in the language used:

Type for instance "fg" to toggle the cell at row f and column g
Hit enter to calculate the next generation
Type q to quit
That really is Brainfuck.
