opAssign in FilePath

Reported by: keinfarbton Assigned to: kris
Priority: major Milestone: 0.99.9
Component: Tango Version: 0.99.4 Frank
Keywords: Cc:


The assignment operator cannot be overloaded for rvalues that can be implicitly cast to the lvalue type.

Doing so results in a compiler error. But doing it via an alias, as done in, the compiler does not complain.

But trying to nullify a ref result in compile error:

auto fp = new FilePath( "/tmp" );
fp = null;
t.d(14): Error: overloads FilePath(FilePath path) and FilePath(char[] path) both match argument list for set
t.d(14): function called with argument types:
matches both:

  • owner changed from sean to kris.
  • component changed from Core Functionality to Tango.

  • milestone set to 0.99.5.

This one is unfortunate as the repercussions from removing it are bad.

tango.text.Text.Text has the same problem.

Clearing my mind, I was thinking about static opCall. Know less about opAssign in this case just yet.

  • status changed from new to assigned.
  • milestone changed from 0.99.5 to 0.99.6.

Any suggestions, keinfarbton?

removing the opAssign?

02/23/08 05:42:54 changed by kris

That would break existing code :(

This appears to be a language issue, and I can't see a way around it since it should be legitimate to use opAssign in this manner.

  • milestone changed from 0.99.6 to 1.0.

Really don't know the best way to approach this

  • keywords set to triage.

If this is considered a spec/compiler bug, does a bugzilla report exist?

Frank - I think perhaps the best way to deal with this is to use instead, if that is possible?

11/14/08 09:16:01 changed by larsivi

I'm not sure I understand this one - if the opAssign doesn't work, how can it then be used/break anything if removed?

11/09/09 03:14:56 changed by kris

  • status changed from assigned to closed.
  • resolution set to fixed.

(In [5069]) fixes #860 :: opAssign in FilePath?

Removed the alias, though doing so removed the ability to set the path via opAssign()
