Comparison of Common Lisp macros and Forth metaprogramming capabilities -



Comparison of Common Lisp macros and Forth metaprogramming capabilities -

every mutual lisp programmer knows macros powerful tool. mutual lisp macros have been used, among other things, add together object orientation on top of lisp without changing language specification; read-macros build mind bending capabilities.

another programme allows meta-programming forth. forth in different manner, using 'words' , 'generate words'.

i know, dabbled in both languages, if mutual lisp macros , forth constructs comparable in breadth/power: there can former can't latter? or vice-versa?

of course, not talking turing-completeness of 2 languages: talking metaprogramming capabilities. c turing-complete fool state c macros comparable in powerfulness mutual lisp ones.

in view, mutual lisp macros similar forth immediate words. (actually, similar lisp reader macros.)

they both procedural macros, i.e. can utilize total powerfulness of language.

they both have access source code input.

they both can output expressible in language. (e.g. object-oriented extension in lisp, or basic command flow constructs in forth.)

the main difference, perhaps, forth "macro" input character strings, while lisp macros operate on parse tree.

Set Up Of Common Name Of SSL Certificate To Protect Plesk Panel -

Set Up Of Common Name Of SSL Certificate To Protect Plesk Panel - a pci compliance scanner balking self signed ssl certificate protecting secure access plesk panel contains name mismatch between location of plesk panel , name on certificate, namely self-signed cert's name "parallels" , domain reach plesk 'ip address:8443'. so figured go ahead , free ssl certificate seek fiddle error. when generated certificate used server domain name site name when generated certificate. if visit 'domain name:8443' fine, no ssl warning. if visit 'ip address:8443' (which believe scanner does) certificate name mismatch error, digicert's ssl checker says certificate name should ip address. can generate certificate mutual name ip address? tempted should pci scanner accepts, right mutual name use? run issue before? you can seek subject alternative name extension ip address. also, can maintain "parallels" mutual name, , add together ...
