Release Notes edit
HLD 2005-01-28 Release NAP version 4.0.3NAP (a.k.a. Tcl-nap) stands for N-Dimensional Array Processor. This is based on a loadable extension of Tcl written in C. NAP provides the essence of array-processing languages such as APL, J, IDL and Matlab and allows large quantities of binary data to be processed efficiently.The NAP home page is http://tcl-nap.sourceforge.net/ This contains a link labelled 'Files for downloading', which can be used to access source files and starpack installers for Windows, Linux (both 386 and IA64) and Solaris.The main documentation of NAP has been greatly revised and is at http://tcl-nap.sourceforge.net/contents.htmlA revised version of my talk on NAP at the 9th Annual Tcl/Tk Conference, 2002 is at http://tcl-nap.sourceforge.net/nap_paper2002.pdfInstallation is now much simpler than earlier versions. Starpack binary installers are provided (see above). The Windows installer includes the ezprint utility (providing access to printers), but there is no longer any other dependence on other packages such as BLT and Michael I. Schwartz's printer. NAP now provides the functionality previously provided by our (now obsolete) separate packages convert_date, inform and land_flag.There has been some development (and bug fixing) of the C code over the last year or so but this code is now quite stable. However a great deal of work has been done on the NAP library written in Tcl. This includes GUIs for browsing various types of files (e.g. netCDF, HDF) and plotting graphs and images. pdf AM So, with the starpacks and all that, NAP has become ready for use? That is good news. (I will have to find some time to try out this new version)HLD 2005-08-11 Release NAP version 5.0.5Version 5 is a major release featuring:
- New parsing process involving parse-tree - Removal of restrictions on unary operators "@", "@@" and "@@@" - Better error handling - Support for OPeNDAP (aka DODS) (currently only for 386 Linux) - Bug fixes - Resolution of differences between Peter Turner's and my versions of netCDF/HDF GUIsThe starpack installers for Windows, Linux (both 386 and IA64) and Solaris can be accessed using the link labelled 'Files for downloading' on the NAP home page: http://tcl-nap.sourceforge.net/

AM Here is a simple application of NAP: Analysing geographical data with NAPNB and another: Analyzing Remote Sensing Data with NAPJBR 2012-02-16 - Trying to build NAP.NAP is a very interesting project that I've toyed with using for a long time but its tangled up with HDF and NetCDF which I have no use for. This morning I tried to build it but failed:

If NAP was re-packaged with the file formats as configure options that would be ideal (but I understand that the world is not an ideal place).Thanks.
Nap versions from 6.2 - 7.0 do not load, with the error "couldn't load library "C:/Tcl/bin/nap6_2.dll": invalid argument"... This is Win 7, AS 8.6.4.1 (64 bit)... Any ideas?
