Has anyone already written a tool, that compiles and runs the program?As far as I know, the "!/something just means, start /something, and pass current filename as a commandline param ?
In general, "pass all parameters" allowing that unix doctrine expects an implicit zeroeth parameter which is the name of the current program.
So all your tool has to do is write all except the first line to a temp file, compile temp file and execute it ?
If I recall correctly, Rexx has special handling for the first line which- intentionally or otherwise- facilitates shebang handling. Also I'm reminded of a Perl option which causes it to throw away anything before valid scripting.
Would it be feasible to modify FPC so that it discarded everything preceding "program", "unit" etc?
