- add toScalar evaluation, embedded as "${{EXPR}}".
For example,
"repeat ${{5 * 7}} times or ${{ pow(3, 10) }}"
- use direct string concatenation if primitive entry is only a string
type. This prevents spurious quotes from appearing in the expansion.
radius "(2+4)";
angle "3*15";
#eval "$radius*sin(degToRad($angle))";
We want to have
'(2+4)*sin(degToRad(3*15))'
and not
'"(2+4)"*sin(degToRad("3*15"))'
ENH: code refactoring
- refactored expansion code with low-level service routines now
belonging to file-scope. All expansion routines use a common
multi-parameter backend to handle with/without dictionary etc.
This removes a large amount of code duplication.
