Passing data to templates and using pipelines

- So the next step for us in the process…is to take our data and to be able to pass that…into the template when it executes…so that we can then merge our data with our text,…our form letter, our spam emails, our HTML web pages.…And to do that, we're going to use…this concept of pipelining.…So we're going to be looking at these files,…and right now, we're looking at this main.go…from right here where I have some data structures.…But first, I sort of want to take…a quick look at pipelining.…So pipelining is this concept in Unix…where the output of one process…becomes the input of the next process,…and so there's your pipe, and it's…also like a pipeline because it's…just going down the pipe this way.…

So it'll be like, hey the output of this program…becomes the input of this program.…The output of this program…becomes the input of that program,…and so we could see that in action with passing data…into templates where if I have these data structures,…and you know, I pass year in my template…when it executes, years made up of a bunch of semesters,…
