Package: svn-load
Version: 0.6-1
Severity: normal
Tags: patch
When including several lines in a move-map file which use the
convenience feature of specifying a string instead of a lambda,
that string is not stored properly for each line. Instead, the
last string in the file will be used with each regexp. For example,
if the move-map file contains
^foo$ "hello"
^bar$ "world"
this will in fact be interpreted as
^foo$ "world"
^bar$ "world"
The reason for this is that the variable "value" used in the lambda
is shared between all the lambdas. In lieu of proper lexical scoping,
there is a trick to get around this: Add a second parameter with a
default value. Since default values are stored in the lambda, this
will allow the lambdas to keep different values.
