PR# 11044 Please normalise the path to $file_name in External Commands

When $file_name is expanded to execute an external command, it is simply the concatenation of the class's cluster path plus its file name.

This can result in a path that contains dots.

Apart from looking messy when displayed, some applications do not work unless the path is normalised.

Please normalise the path generated by $file_name. For example, instead of "c:\projects\sample\.\root_class.e", please generate "c:\projects\sample\root_class.e".

There is a work-around for this on windows. Instead of this command:
echo "$file_name"
Issue this command:
for %i in ("$file_name") do echo %~fi

1. Create an external command echo "$file_name".

2. Open a class in the editor that is in a cluster whose path is ".".

3. Run the external command. Notice how the path displayed includes the dot, e.g., "c:\projects\sample\.\root_class.e".
