My emacs is set up to automatically indent my code as I write it and also re-indent things correctly if I push tab on any line that got misaligned somehow (usually because I changed the code). I am wondering, though, if there is any command in emacs that would allow me to take an entire file (with a code written in it) and indent the whole thing automatically the same way it normally indents my code real time as I write it without me having to go through and push tab on every line of the file?I suppose I could define a macro that tabs and then advances to the next line and repeat that macro for the length of my file. I am wondering though if there is any command in emacs or some other feature that would do this automatically.
Can I have emacs automatically indent my whole code after it is all written?

You can indent the region, to do this for the whole buffer:mark whole buffer with C-x h (or M-x mark-whole-buffer)run indent region with C-M-\ (or M-x indent-region)
