## 6 Frequently Asked Questions

> Q. How do I re-indent the whole file?

> A. Visit the file and hit `C-x h` to mark the whole buffer. Then hit `ESC C-\` to re-indent the entire region which you’ve just marked. Or just enter `M-x vhdl-indent-buffer`.

> Q. How do I re-indent the entire function?

> A. Hit `ESC C-h` to mark the entire function. Then hit `ESC C-\` to re-indent the entire region which you’ve just marked.

> Q. How do I re-indent the current block?

> A. First move to the brace which opens the block with `ESC C-u`, then re-indent that expression with `ESC C-q`.

> Q. How do I re-indent the current statement?

> A. First move to the beginning of the statement with `ESC a`, then re-indent that expression with `ESC C-q`.

> Q. I put `(vhdl-set-offset 'statement-cont 0)` in my `.emacs` file but I get an error saying that `vhdl-set-offset`’s function definition is void.

> A. This means that VHDL Mode wasn’t loaded into your Emacs session by the time the `vhdl-set-offset` call was reached, mostly likely because VHDL Mode is being autoloaded. Instead of putting the `vhdl-set-offset` line in your top-level `.emacs` file, put it in your `vhdl-mode-hook`, or simply add the following to the top of your `.emacs` file:

>     (require 'vhdl-mode)

> See the sample `.emacs` file Sample Init File for details.
