What are the operators available in tlcore? If we are loading up the integer library, we should provide the operations therein, as in the five operators. Is this done?

intmp<5>This is neat, here are a few comments.
1. The output from the equations section should be separated from the output from the expressions section with a %%.
2. The uuid “4557f67592cb498fa684d50f5511a65” should read “uuid<4557f67592cb498fa684d50f5511a65>“.
3. The output from the equations section is not taking into account the –verbose option.
4. In –verbose mode, we should output equations, demands and expressions as eqn<…>, dem<…> and expr<…>, respectively.
5. Should there be ;; at the end of each line of output?
6. Should there be a separator between the input and output? As in a line —?

uuid or uuid … ?
The rest is easily fixed.-

Problems with angle brackets. Now fixed.

and my reply got broken with the angle brackets too, that doesn’t say what I intended it to.

The fix looks good. Points 5 and 6 should be tried out. For point 6, that is two dashes on a separate line, to separate the input lines from the output lines. In the reactive mode, there should be two lines with two dashes, before and after each output. If this is too verbose, we can remove it.

Yes, the trick is that SorceForge tl doc pages is not updated automatically with the your updates. Local copies do look better. Can this be done automatically?

I’m not sure how to do this automatically. I can at least make a script that uploads the latest documentation, and then we would need to rebuild it every now and then as we add to the code.

Jarryd, why the “TransLucid Doxygen documentation” doesn’t include all the methods available to a class? Unless I’m missing something, I can’t find the class “Translator” under the class list, only under the “TransLucid Namespace Reference” and there, I can’t find the methods available. Is there a trick?

The “tlcore with demands” and “reactive tlcore” entries have been updated: The ## has been replaced with $$.

Current todo list
This is the current list of features that are required to work to make tlcore begin to be useful. The important system at the moment is the reactive one.

- add a uuid type to allow the manipulation of equations

I don’t understand the question.
tlcore has no built in operators, they all come through loading the integer library and declaring things in the header. Are you wanting some of this to be automatic?
To which five operators are you referring? There are plenty that we could have, all the arithmetic and comparison operators, we could have bitwise operators too. It’s partly a question of how we can implement these with a minimum of typing too.

I think that there should be a default set of operators. We can always use a flag to turn these on and off. For integers, at the minimum, +, -, *, /, %. For comparison, we have a problem with the angle brackets, we could use ge, gt, le, lt.

Parsing negative numbers is also problematic if we are not using the intmp interface. I propose that we do the same as in Haskell, and use the tilde (~) to indicate a negative number. That way there will be no confusion between ~3 (negative-three) and -3 (the negation operator applied to three).
jarro2783 04:04 on 2010/08/30 Permalink |
I forgot about the angle brackets. Although only < is a problem. Using tilde is a good idea. I think having a default set of operators is a good idea too. We should come up with a reasonable set of associativities and precedences and allow them to be redefined.
