[Tcllib-devel] Proposed modules/packages

[Andreas K. <aku...@sh...>]

Attached a few zip archives containing modules/packages which could be
added to tcllib.

virtchannel_base.zip
	Module 'virtchannel_base', additional packages/channels
	Tcl 8.5+

	facade - An implementation of Wub's IChan, using logger for
	       	 debugging and written as base-class instead of mixin.

		 A channel wrapping around another channel logging
		 activity and providing life-time information.

	std - Provides a singleton channel putting stdin and stdout
	      into a single read/writable channel.

	cat - Concatenation of multiple channels (similar to facade,
	      but multiple inputs, not seekable). Reading from the
	      channel returns the data from all the subordinate
	      channels in turn. Useful for streaming complex data
	      build up out of many smaller pieces, in memory, on file,
	      etc. (Example of a possible use: mime module not having
	      to construct a mail with large attachments in
	      memory. Only the various pieces, with the attachment
	      just one channel in the whole concatenation.)

http.zip
	Module 'http', new package 'http::intercept'.
	Tcl 8.5+ ( {*} )

	To intercept http::geturl commands and serve them out of a
	database of url/response mappings.
	Useful for testing http-based protocols.
	Incomplete.

try.zip
	New module and package 'try'.
	Tcl 8.5+ ( {*}, lassign )

	When Donal implemented try/finally in 8.6 he wrote a Tcl
	implementation first, before going to C. This here contains
	said Tcl implementation, nicely wrapped as package.

	I.e. forward compatibility.

lambda.zip
	New module and package 'lambda'.
	Tcl 8.5+ ( {*}, apply )

	Simple wrappers around ::apply to make it easier (more
	proc-like) to write anon procedures.

	These are so simple, they could be added to the core. Still,
	let us put them in Tcllib first, for hopefully quicker
	distribution, and to see if they are actually used.

dictutil - Still working through Dict.tcl. Issue is less copying the
	 code over, but writing docs.
