Hello Ralf,
According to Ralf Wildenhues on 3/21/2008 1:18 AM:
| Hmm. That means my current AM_COND_IF patch will treat
|
| AM_COND_IF([OUTER],
| [$outer_action
| AM_COND_IF([INNER],
| [$inner_action])])
Look at autom4te.cache/traces.?, with lines like:
m4trace:configure.ac:3: -1- AM_COND_IF([OUTER], [$o AM_COND_IF([INNER],
[$i])])
m4trace:configure.ac:3: -1- AM_COND_IF([INNER], [$i])
|
| correctly but mistreat
|
| AM_COND_IF([OUTER],
| $outer_action
| AM_COND_IF([INNER],
| [$inner_action]))
m4trace:configure.ac:5: -2- AM_COND_IF([INNER], [$i])
m4trace:configure.ac:3: -1- AM_COND_IF([OUTER], [$o ...])
|
| That's a bit ugly, and certainly deserves mention.
I think I see a way around the problem. Use the nesting level, which is
also part of the trace. For example, autoconf --trace=_AM_COND_IF:'$n-$d'
can tell you that _AM_COND_IF-2 was probably invoked unquoted within
_AM_COND_IF-1. For more assurance, you can also start looking at line
numbers in the trace to ensure that the subsequent _AM_COND_IF-1 occurs on
the same or earlier line than _AM_COND_IF-2, rather than the _AM_COND_IF-2
being nested in an unrelated macro call.
Hmm. --trace=MACRO is documented in autoconf/autom4te --help, but not
- --trace=MACRO[:FORMAT]. Should we document that in more than the manual?
| Happy Easter,
Same to you.

Don't work too hard, make some time for fun as well!
