CLASP & libCLImate : different language implementations converging

I'm working on CLASP and libCLImate for Ruby, Go, .NET at the moment, and they're getting close to a 1.0 release, particularly CLASP.

There've been two recent releases of CLASP.Ruby:

  • 0.17 adds a CLASP::Arguments.load() method, which takes a Hash or YAML-containing file (actually an IO type), containing definitions of the flag/option/alias specifications;
  • 0.18 changes the name of the concept from alias to specification, removing the ambiguity that's been bugging me for years.
The same changes will be made in the Go and .NET versions shortly. The Python and Node versions will change in the medium term.

Once all the other variants are done, the original C/C++ library will be done.

Lots of new things to Go at ...

The Go work is marching on, with the occasionally publicly publishable parts, the most recent of which are:

  • ANGoLS (Algorithms Not found in Go Language Standard library) first release to the world;
  • STEGoL (Simple Testing Enhancements for Go Language) first release to the world;
  • CLASP.Go v0.14.2, much improved and working seamlessly with libCLImate.Go, of which:
  • libCLImate.Go v0.4.1, again much improved.
ANGoLS and STEGoL are new, and so are suffering from the Matt Wilson-disease of poor/missing documentation, but CLASP.Go and libCLImate.Go are now replete with information and examples. Checkout them out. Feedback welcomed.

Watch this space - and the Synesis Twitter and Synesis GitHub accounts - for more Go stuff in the coming weeks. libpath.Go and recls.Go are imminent. Pantheios.Go will be released by mid-year. (And there'll likely be plenty of webservice-related libraries, too, given that's the current focus of Go development here ...)

A bunch of CLASPs

CLASP - Command-Line Argument Sorting and Parsing - is a suite of libraries for sophisticated parsing of command-line arguments and presenting the parsed elements - flags, options, values - in a usable form. The original C/C++ library was released in 2011; variants for other languages have been released from time to time since.

Of necessity (but also enjoying it), currently I'm building systems in a bunch of different technologies, including GoJavascript (NodeB), Python, and Ruby. As such, I have new/updated versions of the CLASP variants for these languages:


Each of the newly-released projects - Go, js, Python - contains  (on GitHub) an EXAMPLES.md file, with links to examples. CLASP.Ruby will provide examples in a forthcoming release.

Simple cat in CoffeeScript

Further to the post "Simple cat in Node", here's a version in CoffeeScript.

#! /usr/bin/env coffee

fs = require('fs')
readline = require('readline')
paths = process.argv.slice(2)

cat = (path) ->

stm = if path then fs.createReadStream(path) else process.stdin

readline.createInterface(
input: stm
).on 'line', (line) ->

process.stdout.write line + '\n'

return

  return

if 0 == paths.length

cat null

return
else

  // process each one at a time
paths.forEach (path) ->

cat path

return


As you can see, it's very simple in structure to the JavaScript version; just simpler and with fewer parentheses. It can be further simplified by removing all the return statements, as every one is redundant in this case:

#! /usr/bin/env coffee

fs = require('fs')
readline = require('readline')
paths = process.argv.slice(2)

cat = (path) ->

stm = if path then fs.createReadStream(path) else process.stdin

readline.createInterface(
input: stm
).on 'line', (line) ->

process.stdout.write line + '\n'

if 0 == paths.length

cat null
else

  // process each one at a time
paths.forEach (path) ->

cat path
