Daniel P. Berrange a3e95abeb5 Document bracket whitespace rules & add syntax-check rule ... This documents the following whitespace rules if(foo) // Bad if (foo) // Good int foo (int wizz) // Bad int foo(int wizz) // Good bar = foo (wizz); // Bad bar = foo(wizz); // Good typedef int (*foo) (int wizz); // Bad typedef int (*foo)(int wizz); // Good int foo( int wizz ); // Bad int foo(int wizz); // Good There is a syntax-check rule extension to validate all these rules. Checking for 'function (...args...)' is quite difficult since it needs to ignore valid usage with keywords like 'if (...test...)' and while/for/switch. It must also ignore source comments and quoted strings. It is not possible todo this with a simple regex in the normal syntax-check style. So a short Perl script is created instead to analyse the source. In practice this works well enough. The only thing it can't cope with is multi-line quoted strings of the form "start of string\ more lines\ more line\ the end" but this can and should be written as "start of string" "more lines" "more line" "the end" with this simple change, the bracket checking script does not have any false positives across libvirt source, provided it is only run against .c files. It is not practical to run it against .h files, since those use whitespace extensively to get alignment (though this is somewhat inconsistent and could arguably be fixed). The only limitation is that it cannot detect a violation where the first arg starts with a '*', eg foo(*wizz); since this generates too many false positives on function typedefs which can't be supressed efficiently.
