ServerJS/System: Difference between revisions

= System Interface =

All platforms must support a module, "system", that may contain the following attributes.

* args: an Array containing the command line arguments for the invoking arguments, not including the interpreter/engine but including the path to the program as it was executed. See also the [[ServerJS/Command Line|Command Line page]].

 

 

 

* [http://github.com/hns/helma-ng/ Helma NG] (in 0.4)

 

 

 

* print: The "system" MAY have a "print" function that forwards its thisp and arguments to "system.stdout.print" with lazy binding (meaning that, if system.stdout is replaced, print MUST forward to the new stdout).

 

 

* fs: a file default file system root object conforming to the File System API

* print (proposal A): The "system" MAY have a "print" function that accepts a "message" and an optional "label" String.

** The label MAY be one of "log", "warn", "error", "pass", "fail".

** Any other, unspecified label MUST be in lower-case and begin with "x" and a vendor-specific label like "x-v8cgi-database".

** '''Counter-argument''' This is infact not printing, but logging. 1) there is lots of logging frameworks, 2) it probably doesn't belong on sys, certainl not called ''print''

*** '''Counter-argument''' However, ''print'' has meant to write a line to stdout in many languages.  That it would frequently be used for logging in non-stdio contexts is not necessarily relevant.
