Clocks

Show the current time in various formats.

Discussion

Many years ago I wrote a trivial little widget that gave the time in various formats. I have rewritten it several times over the years: I did a literate programming version in java, for example. When I saw Pieter Hintjens' beautiful gsl tool I wanted to try it out. Rewriting my clock again seemed a quick, little project.

Prerequisites

1. go

2. gsl

3. tk

What you get

The model.xml file is the meat of the project. It describes how a day is divided into so many seconds for each particular clock and how each division is formatted.

The modelToGo.gsl files converts this model into go when you run it with gsl (or you get the Makefile to run it for you). The generated files are here in the repository (clock.go and clock_test.go) It is all pretty straight-forward.

There is a CLI executable that just reads the library and prints and there is also a server executable that I run on my workstation — I have a tk client (client/clockwisher) running that reads from the server every so often and shows me my clocks. Boom.

clockgsl's Issues

Problem: the model has only been implemented in one language

When I dreamt up the model, I had go in mind and iterated building the model along with the GSL script that targetted go so I fear they might be too tightly coupled.

Part of the glory of GSL is that a single model can serve different GSL scripts and I would like to test that by using the clockgsl model to generate code in a different language. Something that has a printf function: C, perhaps, or Ruby.

Problem: I have to edit the wish client by hand

Derive the wish client from the model

Problem: The makefile does not build the server

Looks like lazy copy and pasting from the cli target.
