Code highlighting for Keynote presentations

gistfile1.md

Step 0:

Get Homebrew installed on your mac if you don't already have it

Step 1:

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

Step 2:

Highlight your source. "highlight -O rtf myfile.php | pbcopy". This will highlight the source code in RTF format and copy the result of that operation to your Mac's clipboard.

Step 3:

Paste into your slide in Keynote. Keynote will create a new text box with your highlighted code. You can adjust the width as needed, and adjust the font size with cmd+ and cmd-

Any solutions for highlighting jsx code?

The following works for VSCODE.. add the following in your keybindings.json

    {
      "command": "editor.action.clipboardCopyWithSyntaxHighlightingAction",
      "key": "shift+cmd+c"
    }

Now any bit of code you want to copy do a cmd + shift + c.
Paste this onto a text editor like TextEdit for mac. Now copy the same code from textEdit and paste onto keynote..

My solution is to use Vim with vim-polyglot installed for syntax highlight

1. Open the file with the code on Vim
2. Use vertical selection (Option+Command + Left Click) on Terminal to select the part of the code I want to put into Keynote.
3. Pasted the copied content into a page in Keynote, the content is already formatted
4. You can customize the formatting even further on Keynote

Notes:

• point 2 works on iTerm as well, but you have to enable the option to copy text with styles.
  Prefs > Advanced > Copy to pasteboard on selection includes color and font style.
• The background color of your terminal is also copied, use Keynote to remove the background color. see this image

I would like to reduce the inter-line spacing : can either highlight or pygmentize handle that?

It seems does not support js. :(

👍

Any plans to add support for --syntax=solidity?

This is really helpful, thanks a lot. However, I can not get background color working, with canvas setting. Any suggestion?

Very nice, thanks
