Here's a patch to make uncrustify honor its align_on_tabstop option when aligning backslashes: [Note: I let a personal preference sneak into this patch. I don't want to align-to-tabstop when there is only one continued line: #define foo \ bar.................

I could have gone either way, but there were far more cases with no spaces, so I put this in the config file: sp_inside_braces_struct = remove # Add or remove space inside '{' and '}' sp_inside_braces = remove # Add or remove space inside '{' and '}' > ---------------------------------------------------------------- > > - while (changed0[i0]) ++i0; > - while (changed1[i1]) ++i1; > + while (changed0[i0]) > + ++i0; > + while (changed1[i1]) > + ++i1; > > The old version is easier to read, since one can visually align the > bodies of the two loops. I agree that sometimes the one-line version is desired. coreutils' sort.c also has code like that would be similarly degraded if we were to convert today.

I have made notes about similar problems in coreutils: # FIXME: teach uncrustify not to do this: # - int (*cmp) (char const *, char const *)) # + int (*cmp)(char const *, char const *)) # There are similar in pr.c: # - (p->char_func) (' '); # + (p->char_func)(' '); > ---------------------------------------------------------------- > > - for (i = *bucket; ; i = eqs[i].next) > - if (!i) > + for (i = *bucket;; i = eqs[i].next) > + if (! i) > > Changing "; ;" to ";;" is questionable.

Agreed, but I've resigned myself to making a few compromises, and so far the price looks right, once we get a few of these nits ironed out.

[Why? Because making the formatting automatic means 1) we don't have to try to catch formatting violations manually, in review 2) it will avoid subtle bugs like this one: http://thread.gmane.org/gmane.comp.emulators.libvirt/23715 ] uncrustify has far more options than indent, and it is maintained. I've attached the .uncrustify.cfg file that I'm using. To see what type of changes would currently be induced, first get the latest uncrustify, git clone git://github.com/bengardner/uncrustify.git build it from source, install it and then run these commands: uncrustify --replace -c ~/.uncrustify.cfg src/*.c # FIXME: make uncrustify treat two "!!" like "!" ? # - tab_index -= !!tab_index; # + tab_index -= ! ! tab_index; perl -pi -e 's/\! \! /\!\! /' src/*.c # FIXME: either teach uncrustify about case_* macros or undo this, post-run # - case_GETOPT_HELP_CHAR; # + case_GETOPT_HELP_CHAR; perl -pi -e 's/ (case_GETOPT_[^_]+_CHAR( \(|;$))/$1/' src/*.c Here is a summary of some nits contributing to the induced 14K-line diff. If any of you can adjust the uncrustify config file I'm using to make that difference smaller, I'd appreciate patches. - I do *not* want it to expand TABs used for comment and backslash alignment, but haven't yet found how to do that, or if it's even possible, in combination with the spaces-only-indentation mode. For example, I don't want this sort of change: - case FTS_DC: /* directory that causes cycles */ + case FTS_DC: /* directory that causes cycles */ - I prefer this spacing, so all of these are fine: - while (!feof (in) && !ferror (in) && sum < BLOCKSIZE); + while (! feof (in) && ! ferror (in) && sum < BLOCKSIZE); - This isn't a big deal either way. There are many of these, so it'd be good to avoid the change. I suspect that there's an option to do so, but haven't looked yet: diff --git a/src/cat.c b/src/cat.c index eebfb97..6a31f8d 100644 --- a/src/cat.c +++ b/src/cat.c @@ -57,11 +57,11 @@ static int input_desc; an 18 digit counter needs about 1000y */ #define LINE_COUNTER_BUF_LEN 20 static char line_buf[LINE_COUNTER_BUF_LEN] = - { - ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', - ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', '0', - '\t', '\0' - }; +{ + ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', + ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', '0', + '\t', '\0' +}; - There are a few more issues marked with FIXME comments in .uncrustify.cfg below. Note that it did highlight a few real indentation nits. For example, in dd.c's skip_via_lseek, one block is indented by 3 rather than by the usual 2 spaces.
