perltidy breaking before '=' ?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I trying to get perltidy to break before an assignment. having

my $bla = 'a string' . 'another string' . 'yet another' . 'too much fo
+r one line';
[download]

perltidy -pbp -l=72 -vt=0 produces

my $bla = 'a string'
    . 'another string'
    . 'yet another'
    . 'too much for one line';
[download]

I would like to get

my $bla 
    = 'a string'
    . 'another string'
    . 'yet another'
    . 'too much for one line';
[download]

TIA Thomas

I'm having a lot of trouble installing Perltidy on my home machine, so I haven't been able to test this. However, looking at the docs, it's seems like you want to add `-wbb="="`, since wbb is "want break before" (there's also wba, "want break after"). Depending on how Perltidy works, this might cause unexpected behavior around tokens like `=~`, but as I've said, I can't test this. Best of luck. Hays	[reply] [d/l] [select]

This strikes me as a rather nit-picky detail, but I can understand why you would want this behavior. The question is: is it only this sort of statement that is making trouble for you? If so, how bad is it just to edit perltidy's output yourself to fix these cases? Or, if there are a lot of these, and they all end up following the same basic pattern, why not try an ad-hoc filter on the perltidy output -- something like: `s/^(\s)(my\s+[^\s=]+)\s(=[^;]+)$/$1$2\n$1 $3/;` [download] For lines that look like `my $var = ...` and lack a semi-colon on the rhs, this substitution will put any indentation that precedes "my", plus another four spaces of indentation, at the beginning of a new line that holds just the "= ..." portion.

If so, how bad is it just to edit perltidy's output yourself to fix these cases? As I understand it, the ideal is to use Perltidy quite often, as one part of the edit cycle, cleaning up any unintentional goofs and restoring to the 'standard' formatting. Perltidy is not a one-time or once-a-month thing, rather it is supposed to be done at least before each time you check your changes back into the repository. So you shouldn't have to clean up after the cleaner-upper. Indeed, it is this problem that has so far kept me from using Perltidy as intended.	[reply]

I dont know how to do exactly what you want, but you may find it easier to use a new tool I've posted to sourceforge - [TidyView] I plan to post a more general announcement to Perl Monks this week. ...reality must take precedence over public relations, for nature cannot be fooled. - R P Feynmann	[reply]
