(oo)Rexx
Here are some (mostly oo)Rexx widgets/programs that are being written and/or used by me.
I have been using all programs in a personal manner under Windows 7. Some (‘filter.orx’, ‘distance.orx’ and ‘json.cls’(not written by me)) are older and I use/used them under Linux too. The newer ones might run on earlier ooRexx versions than the current one, but will run on the current version(4.2.0). Some require 5.0.0 (beta) and will specify that requirement.
Most programs have comments at the beginning explaining their usage; none of them, I think, has explanation when invoked with ? /? -? /h -h or similar methods to obtain some help, except, perhaps, ‘filter.orx’.
If you don't like the filetype extensions used, you can, of course, change them to your own liking without compromising their functionality.

| Name | Description | Source |
|---|---|---|
| Enumeration.cls | A dynamic implementation of an ENUM-like construction as alternative for the OORexx ::CONSTANT directive | show |
| rgb2hsl.rex | A classic rex script to convert a RGB(red, green, blue) colour specification to HSL(hue, saturation, lightness). Argument and return value are 3-word strings representing the values for the argument string or the return string. | show |
| hsl2rgb.rex | A classic rex script to convert a HSL(hue, saturation, lightness) colour specification to RGB(red,green,blue). Argument and return value are 3-word strings representing the values for the argument string or the return string. | show |
| caselessStringTable.cls | A .stringTable subclass supporting caseless .string indexes in upper-, lower- or mixed-case and treat them as equal when processing. | show |
| number.cls | An exercise in subclassing .String class for numbers only. It's usefullnes may be debatable, but here it is anyway. | show |
| distance.orx | Calculates the total distance (in Km) over (a series) of successive latitude/longitude (e.g. 52.254001) pairs in classic Rexx. Can be used interactively from a terminal/console window or in a pipe. | show |
| geoloc.cls | An ooRexx class that defines locations and paths along those locations by their latitude and longitude in Google Earth/Maps notation. Distance between locations and along a path can be calculated. Requires 5.0.0-Beta or later in combination with usegeoloc.orx below. | show |
| usegeoloc.orx | An ooRexx program demonstrating the use of the geoLoc class. Also requires the use of:
|
show |
| nominatim_latlon_from_address.orx | Retrieves an address in a format such as 1600, Pennsylvania Avenue, Wash.... from a latitude/longitude pair. Requires ‘json.cls’ and ‘curl’ (from curl.haxx.se). Also needs ooRexx 5.0.0 or later. | show |
| nominatim_address_from_latlon.orx | Retrieves a latitude/longitude pair in decimal degrees, (e.g. 48.341673 4.148735) from a given address such as 10 Downingstreet London. Requires ‘json.cls’ and ‘curl’ (from curl.haxx.se). Also needs ooRexx 5.0.0 or later. | show |
| decodeGString.orx | Decodes a Google Maps encoded PolyLine string into a (series of) decimal latitude/longitude pair(s). Can be invoked from the command line, as a stage within a pipe, or as a function. | show |
| encodeGString.orx | Encodes a (series of) decimal latitude/longitude pair(s) into a Google Maps encoded Polyline string. Can be invoked from the command line, as a stage within a pipe, or as a function. | show |
| filter.orx | A generalised pipe stage filter. Suitable for ooRexx and Regina | show |
| gtif2hgt.orx | Converts an ASTER GDEM geoTiff elevation file (30x30 meters approximately) to a SRTM (NASA) type 'hgt' file. | show |
| gpx.cls | A rudimentary class demonstrating the use of the "restrictable" class above. Also requires "geoloc.cls" above. | show |
| streamclient.cls | Enables to redirect "standard" streams(e.g. STDOUT, STDERR, but also .TRACEOUTPUT) to a new terminal window in cooperation with "streamserver.orx" below. Also requires David Ashley's "streamsocket.cls" shipped as part of the ooRexx package. | show |
| streamserver.orx | Enables to redirect "standard" streams(e.g. STDOUT, STDERR, but also .TRACEOUTPUT) to a new terminal window in cooperation with "streamclient.cls" above. "streamserver.orx" is a slightly modified version of David Ruggles' "scserver.rex" shipped with ooRexx in the samples directory. | show |
| eventable.cls | A "mixin" class supporting events and event handlers/listeners. | show |
| md5.cls | A class implementing a transient MD5 digest calculation. | show |
| usemd5.orx | An example demonstrating the use of "md5.cls". | show |
| exebitness.orx | Checks the bitness of a Windows executable (EXE or DLL). | show |
| omdbcurl.orx | Shows how to interface with the OMDB movie database.Requires ooRexx 5.0.0.beta | show |
