QuicklookStephen

QLStephen is a QuickLook plugin that lets you view text files without their own dedicated QuickLook plugin. Files like:

README
INSTALL
Capfile
CHANGELOG
package.json
etc...

Installation

Homebrew

brew install --cask qlstephen

Pre-compiled

• Download the latest version of QuickLookStephen
• Unzip
• Copy the file into ~/Library/QuickLook (You can create the QuickLook folder if it doesn’t exist)

Manually Compiled

Compiling the project yourself? Run:

make
make install

Permissions (Quarantine)

If you run into issues with macOS not letting you run the plugin because it's not signed by a verified developer you can follow these steps:

1. Install the plugin using one of the methods above
2. run xattr -cr ~/Library/QuickLook/QLStephen.qlgenerator (sudo if needed)
3. run qlmanage -r
4. run qlmanage -r cache
5. Restart Finder by...
   • Restarting your computer
   • or holding down the option key and right click on Finder’s dock icon, then select “Relaunch” from the menu

Settings

Maximum file size

To keep quickview fast the preview is limited in its number of shown bytes. The default value is 100kB. You can change this using the shell to set your own max size.

defaults write com.whomwah.quicklookstephen maxFileSize 102400

Trouble?

If you’ve installed the plugin, but don’t see any changes:

• Run qlmanage -m and look for the public.data line to make sure a different application's qlgenerator file hasn't taken precedence. (Not all qlgenerator files are in ~/Library/QuickLook/ or /Library/QuickLook/!)
• Make sure you are editing (a) the correct plist of (b) the correct bundle. (For example, you might have two QLStephen plugins. It’s possible the plugin in another directory — perhaps /Library/QuickLook/ — is what is being read.)
• Run qlmanage -r in the Terminal. (This will restart QuickLook, which reloads all plugins.)

If you want to preview some text files that do have extensions (e.g., *.txt), follow these instructions.

Why “QLStephen”?

Because I was listening to Adam and Joe when I first wrote it.
