documents for J standard library stdlib.ijs

Question

is there a detailed document or commented version of J's stdlib.ijs? The Jwiki link does not include much. Are functions in stdlib.ijs for user use or only intended for internal use?

The local installation of copy stdlib.ijs has much more functions than the onlline version.

Answer 1

Have you opened up stdlib.ijs in the online Subversion repository? It has fairly generous commenting. For example, this is the entry for boxopen:

NB. =========================================================
NB.*boxopen v box argument if open
NB.-Box argument if open.
NB.- e.g. if script=: 0!:0 @ boxopen, then either
NB.-   script 'work.ijs'  or  script <'work.ijs'
NB.-
NB.-See also [boxxopen](boxxopen).
NB.-
NB.-Use [cutopen](#cutopen) to allow multiple arguments.
boxopen=: <^:(L.=0:)

That said, I wouldn't mind a better reference myself.

Answer 2

According to the J mailinglist,

Documentation of standard library of J8 is now available as a chapter of the J User manual,

• http://www.jsoftware.com/help/user/library.htm

which is also part of the docs/help addons.
