pipdeptree is a command line utility for displaying the installed python packages in form of a dependency tree. It works for packages installed globally on a machine as well as in a virtualenv. Since pip freeze shows all dependencies as a flat list, finding out which are the top level packages and which packages do they depend on requires some effort. It can also be tedious to resolve conflicting dependencies because pip doesn't yet have true dependency resolution (more on this later). This utility tries to solve this problem.

textacy is a Python library for performing a variety of natural language processing (NLP) tasks, built on the high-performance spaCy library. With the fundamentals --- tokenization, part-of-speech tagging, dependency parsing, etc. --- delegated to another library, textacy focuses primarily on the tasks that come before and follow after. Abstracts away the boilerplate for the stuff you actually care about.

wait-for-it.sh is a pure bash script that will wait on the availability of a host and TCP port. It is useful for synchronizing the spin-up of interdependent services, such as linked docker containers. Since it is a pure bash script, it does not have any external dependencies.

A tool which prints all of the external dependencies a Go project pulls in. Does pretty much the same thing as this sequence:

go list -f '{{join .Deps "\n"}}' | xargs go list -f '{{if not .Standard}}{{.ImportPath}}{{end}}'

npm2dot is a utility which takes a list of NPM modules installed to support a particular package and generates code for dot (part of graphviz) which can be used to generate a visual map of what's there and how it fits together.
