JSON Translate Name R←X(7162⌶)Y

Converts between JSON names and APL names.

When ⎕JSON imports an entity from JSON text whose name would be an invalid APL name, the function converts the invalid name into a valid APL name using a name mangling algorithm. When ⎕JSON exports an APL namespace as JSON text, the process is reversed.

This function performs the same name mangling allowing the programmer to identify JSON entities as APL names, and vice-versa.

Y is a character vector or scalar.

X is a scalar numeric value which must be 1 or 0.

When X is 0, R is the name in Y converted, if necessary, so that it is a valid APL name. It performs the same translation of JSON object names to APL names that is performed when importing JSON.

When X is 1, R is the name in Y which, if mangled, is converted back to the original form.. It performs the same translation of APL names to JSON object names that is performed when exporting JSON.

Examples

      0(7162⌶)'2a'
⍙2a
      1(7162⌶)'⍙2a'
2a

      0(7162⌶)'foo'
foo
      1(7162⌶)'foo'
foo

Note that the algorithm can be applied, even when mangling is not required. So:

      1(7162⌶)'⍙97'
a
