Source code formatting uses 4 column tab spacing, with tabs preserved (i.e., tabs are not expanded to spaces). Each logical indentation level is one additional tab stop.
Layout rules (brace positioning, etc) follow BSD conventions. In particular, curly braces for the controlled blocks of if, while, switch, etc go on their own lines.
Do not use C++ style comments (// comments). Strict ANSI C compilers do not accept them. For the same reason, do not use C++ extensions such as declaring new variables mid-block.
The preferred style for multi-line comment blocks is
/* * comment text begins here * and continues here */
Note that comment blocks that begin in column 1 will be preserved as-is by pgindent, but it will re-flow indented comment blocks as though they were plain text. If you want to preserve the line breaks in an indented block, add dashes like this:
/*---------- * comment text begins here * and continues here *---------- */
While submitted patches do not absolutely have to follow these formatting rules, it's a good idea to do so. Your code will get run through pgindent before the next release, so there's no point in making it look nice under some other set of formatting conventions.
The src/tools directory contains sample settings files that can be used with the emacs, xemacs or vim editors to help ensure that they format code according to these conventions.
The text browsing tools more and less can be invoked as:
more -x4 less -x4
to make them show tabs appropriately.
