Here's where I go "huh." That works, but 1) I don't at all get how the input is passed to the command; and 2) if I call on STDIN.read prior to this line (by using it to get the beginning of the input), then that line fails to get any input, and I have to manually pipe the text back into it. What's happening there?
Well, if you call read(), you consume the input, so it's not there to pass on to the child process.
I was guessing that was the case. But how about the first question, if there is input how does that statement suck it up automatically? (Apologies if this is excruciatingly basic; I'm just trying to understand how the input gets passed without explicitly doing so.)
To put it simply, this is just how Unix works. ;)
Child process inherit STDOUT, STDIN, and STDERR from their parent process.
Here's the code I just moved into the Source bundle. Let me know if this is working please:
It looks like it works well for most cases, but I think the more lenient regex causes a problem in the case of a latex comment such as "%\usepackage" (note no space); in that case, the comment parameter is set to "%" and the backslash ends up causing problems.
If I remove backslash from the characters would that cover us? I don't *think* it's a comment in any language I know...
