treef

The tree formatter.

treef reads paths from stdin and formats them as a tree, like the tree utility. Many tools' output can be piped to treef.

Getting started

Use make to build and install treef.

make
make install    # may require sudo

Take a look at the cookbook for some uses!

Cookbook

The output of a wide range of command line tools can be visualised with treef. Here is a collection of recipes as inspiration, some more useful than others.

List files tracked by Git. This is my savior in projects with build/, node_modules/ etc where tree is too cluttered. I have it aliased to gt in bash for ergonomics. ls-files can also be used to show files in the index, ignored files, modified files and more.

git ls-files | treef

Visualise your .gitignore. Kind of weird with wildstars, but works all right.

treef < .gitignore

Recursively list HTML files. There are endless possibilities here. find has loads of comparators like -mtime, -size and -user.

find . -name '*.html' | treef

Recursively list files containing a magic number. With grep comes the whole power of regular expressions.

grep -lR 123 * | treef

What files are referred to in a ctags file? Just for fun :)

grep -v '^!_' tags | cut -f 2 | treef

Testing

Run automated tests with

make test

The tests will run with Valgrind's memcheck if installed. See TESTING.md.
