[fpc-pascal] Parameterless constructors are not allowed in records or record/type helpers

Why is this restriction in place and what are the alternatives if any? Some times I want to just provide a method that sets default values for a record without any parameters but FPC doesn’t let me for some reason. Regards, Ryan Joseph ___

Consider this program, which returns False: program Project1; uses sysutils; var : boolean; begin :=IsValidIdent(''); WriteLn('IsValidIdent() evaluates to ', ); end. Should sysutils.IsValidIdent() be updated to return True in this case?

I never knew Pascal had default parameters, a feature I always use and enjoy in PHP. Once again I learn something new about the language I use. :) However, the constructor with default params does not work. I get the same error as before. {$modeswitch advancedrecords} is on. type

Several years ago I seem to remember using a FPC tool that allowed me to write Pascal code and have its source file loaded, compiled and executed at the command line. If I remember correctly, it kept access to the environment that it was being executed immediately under and so was like a

Re: [fpc-pascal] Parameterless constructors are not allowed in records or record/type helpers

I tried class functions in records already but I got the error "Class methods must be static in records”. Not sure what that means but I assumed they don’t work either. Too bad, that would be a nice feature. > On Feb 6, 2017, at 2:29 AM, Sven Barth wrote: > > Oh,
