This is a standalone document previewer based on macOS's built-in
Quick Look engine——imagine a nicer qlmanage. It's particularly
useful for using from the command line or inside terminal
applications, like mutt.
You can either download a pre-built release, or build it yourself.
When getting the current release, install it like any other
application: open the disk image and drag the app to your
Applications folder.
When building it yourself, make sure you have Xcode installed. Either
use that to open and build the project, or just run make from the
command line. You will then find the application in
build/Release/qlview.app.
You can start qlview from the Finder, and it'll open an empty window
where you can drag a document into. More usefully, you can open
documents from the command line through a custom URL scheme:
# open qlview:/path/to/file
To use qlview with mutt, there's a helper
script
mutt-qlview
coming with the distribution. Put that script into your PATH and
then add these mailcap
entries to
your mutt configuration. See mutt's
manual for more on that.
You can also add the following to your .muttrc to quickly open the
first HTML attachment in qlview:
macro index,pager V <view-attachments>/html\n<view-mailcap><quit>
