tq is command line utility that performs an HTML element selection on HTML content passed to the stdin. Using css selectors that everybody knows.
Since input comes from stdin and output is sent to stdout, it can easily be used inside traditional UNIX pipelines to extract content from webpages and html files.
tq provides extra formating options such as json-encoding or newlines squashing, so it can play nicely with everyones favourite command line tooling.

Notice that tq doesn't provide a way to make http requests or read files. You can use your favorite HTTP client, or provide the html source from any source you want.
For a modern, user friendly http client, check httpie. Or you can just use curl, wget, netcat, etc.
