Hello, Any thoughts/guidance on creating a modern incarnation of NLEdit, http://hdl.handle.net/2060/19950007792 NLEdit turns Fortran namelists, which look like, &body_definitions n_moving_bodies = 1, ! number of bodies in motion body_name(1) = 'FreeFall', ! name must be in quotes parent_name(1) = '', ! '' means motion relative to inertial ref frame / &forced_motion rotate(1) = 0, ! rotation: 0=none,1=fixed rate,2=sin(kt) rotation_rate(1) = 0.0, ! rate of rotation rotation_freq(1) = 0.0, ! reduced rotation frequency / (where '!' is a comment character) into GUI forms with the help of an intermediary file that provides meta data about each variable, e.g., valid range, type, etc. I was thinking tabbed web pages, one per namelist, with some sort of DSL to get us from namelist to web form by using the comment field.
