[Swift-user] single structs for ext mapper.

[Allan Espinosa]

Hi

How do you use ext mapper for single structs? I used a $.xxx but swift
does not recognize that.

I have the workflow below based on 0755-ext-mapper.swift:

type messagefile;

type cols {
  messagefile l;
  messagefile r;
}

(messagefile t) write(string s) {
    app {
        echo s stdout=@filename(t);
    }
}

cols outfile <ext; exec="./0755-ext-mapper.sh">;

outfile.l = write("slot 0");
outfile.r = write("slot 1");

mapper file 0755-ext-mapper.sh:
echo "$.l 0755-ext-mapper.AAA.out"
echo "$.r 0755-ext-mapper.0.3.2.1.out"

session:
[aespinosa at communicado struct_ext]$ swift 0755-ext-mapper.swift
Swift svn swift-r2998 cog-r2410

RunID: 20090710-1424-49r93eqg
Progress:
Execution failed:
        java.lang.IllegalStateException: mapper.existing() returned a
path .$.l that it cannot subsequently map


thanks,
