Code Block

Creating a fixed width code block is recommended for pasting multi-line blocks of code or other text output that is easier to read with fixed width font alignment. Examples include block text snippets, ASCII tables, and log files.

This can be accomplished in one of two ways:

  1. Placing 3x backtics ``` on the line directly above and directly below your code

this is my
code block
  • TIP - Enter 3x backticks ```, SHIFT + ENTER, <type_your_code>, SHIFT + ENTER, and finally 3x backticks ```.

  1. Indenting each line by four spaces

    this is my
    code block

^^^^ 4x spaces

Syntax Highlighting

To add syntax highlighting, type the language to be highlighted after the ``` at the beginning of the code block. Smeetin also offers four different code themes (GitHub, Solarized Dark, Solarized Light, Monokai) that can be changed in Account Settings > Display > Theme > Custom Theme > Center Channel Styles

Supported languages are: actionscript, applescript, bash, clojure, coffeescript, cpp, cs, css, d, dart, delphi, diff, django, dockerfile, erlang, fortran, fsharp, gcode, go, groovy, handlebars, haskell, haxe, java, javascript, json, julia, kotlin, less, lisp, lua, makefile, markdown, matlab, objectivec, ocaml, perl, php, powershell, puppet, python, r, ruby, rust, scala, scheme, scss, smalltalk, sql, swift, tex, vbnet, vbscript, verilog, xml, yaml

In-line Code

Create in-line monospaced font by surrounding it with backticks (`), not with single quotes (‘).


Renders as: monospace.

In-line Images

Add in-line images by using an exclamation mark followed by the alt text in square brackets then the URL of the image in round brackets. You can add hover text by placing the text in quotes after the link.

![ {alt text} ]( {URL of image}{Hover text})

If the height of the original image is more than 500 pixels, the system sets the height at 500 pixels and adjusts the width to maintain the original aspect ratio.

You can set the width and height of the displayed image by using an equals sign and the width x height after the URL of the image. If you set only the width, the system adjusts the height to maintain the original aspect ratio.

Create a table by placing a dashed line under the header row and separating the columns with a pipe |. (The columns don’t need to line up exactly for it to work). Choose how to align table columns by including colons : within the header row.

| Left-Aligned  | Center Aligned  | Right Aligned |
| :------------ |:---------------:| -----:|
| Left column 1 | this text       |  $100 |
| Left column 2 | is              |   $10 |
| Left column 3 | centered        |    $1 |
