Features

Nice-to-haves copied from the manpage of tree.

-l	Follows symbolic links if they point to directories, as if they were directories. Symbolic links that will result in recursion are avoided when detected.
-f	Prints the full path prefix for each file.
-L level	Max display depth of the directory tree.
-P pattern	List only those files that match the wild-card pattern. Note: you must use the -a option to also consider those files beginning with a dot `.’ for matching. Valid wildcard operators are `*’ (any zero or more characters), `?’ (any single character), `[…]’ (any single character listed between brackets (optional - (dash) for character range may be used ex: [A-Z]), and `[^…]’ (any single character not listed in brackets) and ‘pipe’ separates alternate patterns.
-I pattern	Do not list those files that match the wild-card pattern.
–filelimit #	Do not descend directories that contain more than # entries.
-o filename	Send output to filename.

note: uiop has (uiop/filesystem:resolve-symlinks)

Topics

explicit dir: tree a prints a, tree . prints ., tree ../xy prints ../xy as root and so on

relative paths are printed relative, absolute absolute. Maybe this means tree needs to take

care of building paths?

License clashes with other libs?

fiveam: custom? but no redistribution?

unix-options: LLGPL

performance measuring

mark pure functional and imperative

full tests: simple syntax for creating test file structures?

TODOs

changelog

ease running tests

measure code coverage

travis CI

are 5am tests really global scoped? might cause problems

redefine package exports? how?

revert line length?

turn change-file-header into lisp
