Martin Atkins	f91a3b87c1	terminal: Helpers for doing fmt-ish operations on the streams ... It's pretty common to want to apply the various fmt.Fprint... functions to our two output streams, and so to make that much less noisy at the callsite here we have a small number of very thin wrappers around the underlying fmt package functionality. Although we're aiming to not have too much abstraction in this "terminal" package, this seems justified in that it is only a very thin wrapper around functionality that most Go programmers are already familiar with, and so the risk of this causing any surprises is low and the improvement to readability of callers seems worth it.	5 years ago
Martin Atkins	ffba8064ed	terminal: StreamsForTesting helper ... This is to allow convenient testing of functions that are designed to work directly with *terminal.Streams or the individual stream objects inside. Because the InputStream and OutputStream APIs expose directly an *os.File, this does some extra work to set up OS-level pipes so we can capture the output into local buffers to make test assertions against. The idea here is to keep the tricky stuff we need for testing confined to the test codepaths, so that the "real" codepaths don't end up needing to work around abstractions that are otherwise unnecessary.	5 years ago
Martin Atkins	17728c8fe8	internal/terminal: Interrogate and initialize the terminal, if any ... This is a helper package that creates a very thin abstraction over terminal setup, with the main goal being to deal with all of the extra setup we need to do in order to get a UTF-8-supporting virtual terminal on a Windows system.	5 years ago
