Compile text using command line compiler, not a file
I'm using luac -p file.lua to parse files to check for syntax errors. Is it possible to do something like this:
luac -p | [a bunch of text]
Someone mentioned something about 'piping' but I couldn't figure out how that would help.
What I'm wanting to do is take text from a program I am writing and put all that text into the compiler with -p so it just parses the text. Basically I want to check syntax of my program's textarea without having to write it to a file first.

Are you using Windows command line for this? If so you can loop it like sofor %a in ("C:Folder*.lua") do luac -p | "%~a"....

c:folder*.lua seems to refer to a file. I'm trying to compile text without a file - maybe from the clipboard or just adding all the text into the command prompt. I'm doing this from java Process execution. (also a side note, I'm hoping to get this working with mac and windows)

Yes,luacaccepts program from stdin:luac -p -So, just runcat program.lua | luac -p -

Not sure how that works... what is program.lua? remember, I have no file, it's text going into the terminal.

In bash you can do
luac -p - << EOF
Then type your text. To indicate end, just type
EOF
on new line and press enter.

I triedluac -p - << print("Hello) n EOFand it just starts luac or something and doesn't return the error which is the missing " in that text.
