Description editSome modules of Tcllib include high-performance implementations written in C with the help of Critcl. The typical package require ... automatically makes use of the more performant variants if possible. To check whether these more performant variants are available:
package require tcllibc

Misc edit2004-05-25: Has the tcllib team considered adding some form of Michael Cleverly's package, nstcl? While most functionality is duplicated in the current distribution of tcllib, the nsset datatype is a wonderful thing to have; an indexed array! [index - key - value]. His api has some commands to utilize it as well. As an aolserver tcl coder, I work with it extensively and for me it renders the array command obsolete. APN The 8.5+ dict built-in seems to be a superset of this.
set id [ns_set create] %t2 ns_set put $id fname Michael %0 ns_set put $id lname Cleverly %1 ns_set get $id fname %Michael
As documented above, it generally isn't a matter of some team determining whether some code is worthy to add. It is typically a matter of some interested party contacting the tcllib maintainers to work out the details of their adding a new module to the library. Why not contact Michael and ask if he would like to add his code to tcllib? Over the years, it has turned out to work better if the author is involved with this process, so that no misunderstandings, etc. occur.
History editWhen Tcllib was originally released, the following was written:In response to popular demand, the Tcl core group is introducing tcllib, a Tcl standard library. This meta-package will contain many modules, each of which is itself a standalone Tcl package. The intention is to provide commonly-used functions and libraries, bundled together under a single license (BSD), and with no binary dependencies. This will encourage use and growth of the library. Once tcllib is downloaded and installed, users will be able to "package require tcllib" or "package require any_module_in_tcllib".Releases of tcllib will be made mostly independently of releases of the Tcl/Tk core. This will allow a faster release cycle, which is important in the early stages of development. It is possible that future releases of the core will include a snapshot of the tcllib.Initially, we have seeded the library with several modules, some written in-house at Scriptics and by the core group:
- Tcl implementations of common data structures
- Function level Tcl profiler
- getopt style command-line parser
- base64 encoder/decoder
- Tcl implementations of file utilities (grep, find, ...)
- pop3 client
- math functions (min, max, ...)

I thought your proposed set of functionality sounded interesting. Some folks have shown interest in having access to the functionality available through the NumPy package (a python package) in tcl. This might give you ideas for things that people might want. The NumPy package is at: http://sourceforge.net/projects/numpy/ I think the process for volunteering to work on a project there is to contact an admin for a project. Currently [AK] has been organizing tcllib development, so it might be worthwhile to contact him Currently the web page that talks about tcllib (a little out of date) is at: http://www.purl.org/tcl/home/software/tcllib/ As far as guidelines for contributing, I think the current requirement is that things in tcllib must be able to be run in a tcl-only mode (i.e. no binary package dependencies), and the contributed code should have either tests or documents, but preferably will have both. There are good contribution guidelines (that also contain a link to the Tcl Sytle Guidelines) at: http://www.purl.org/tcl/home/software/tcltk/contributing.tml (while that page is focused on contributing to tcl/tk, most of it is relevant to tcllib as well). I hope that helps get you started! --Dan
Targeted Tcl versionsAMG: What versions of Tcl does tcllib target?RLH: This is what I was told when I asked that on comp.lang.tcl:
Statically, you would have difficulties if you have 8.4. You have also, for instance "snit" which is an important package used by others that now requests 8.5, so with less bugs than previous edition, in the end 8.5 is mandatory and most of tcllib 1.18 will work with it.
Forward compatibilityAMG: If Tcllib is intended to support both 8.4 and 8.6, would it be appropriate to include 8.4-compatible pure-Tcl implementations of 8.6 commands? For example, I just finished writing a [dict] command that works in 8.4 yet passes most of the 8.6 test suite . That might be a good fit. There are many other possible commands to consider, for instance [lassign]. See Forward compatibility for more.RLH: Looking at the tcllib docs, json is under "CGI Programming" and it really shouldn't be. JSON is a data interchange format used for much more than "CGI Programming". So maybe "CGI Programming" needs to be renamed "Web Technologies" or another category altogether. Just a thought.
