treesnek_demo.mov
A shameless imitation of tree to print a nice looking recursive tree of the current directory in your terminal, written in Python.
treesnek "grows" the directory tree by recursively adding the directory's contents to a dictionary to the specified depth limit (TreeGrower.path_data()), then sorting the dictionary by type (directory or non-) then name (possible since Python 3.7).
Then it generates a tree by creating a list of strings that represent the tree (TreeGrower.generate_tree()) as if you were slicing the tree horizontally, adding connective branches along the way. Again, it uses recursion to reach the maximum depth set by the limit flag (--l), returning once it hits the limit. But, rather clumsily, it adds branches that go nowhere as it creates this list because it doesn't know if a sub-directory is the last one in its own folder until that sub-directory is done printing its own contents. That's confusing, so here's a picture of what treesnek would output without calling the TreeGrower.prune_tree() function.
The circled branches don't go anywhere, but I couldn't figure out an efficient way of calculating when the program should draw the vertical line. So instead, we generate the List[str] and then go back and "prune" it: if the char above any pipe │ char is a corner/elbow └ or an empty string (meaning a pipe was pruned there in the previous row), we prune that pipe, but really we're redrawing the whole tree.
In any directory in your terminal, use the treesnek command available after install.
treesnek takes two optional arguments:
--hto show hidden files--lto control the level of directory depth to print (default 1). e.g.treesnek --l 5
