More deliberate TDD practice in my open source projects


My Erlang-like interpreter in C#:

I added selective receive to process mailboxes. It was an interesting implementation, where each mailboxes has a save queue to keep the rejected messages. Once a message is accepted, the save queue is put again as a message queue, ready to be consumed again.


My Scala interpreter in C#:

I added binary expressions. I started to think about type check implementation. This next week I will add an explicit AST (Abstract Syntax Tree) to be used for type checking. Not all Scala expression can be type checked at parser time, because possible not-resolved cross references.


My Scala interpreter in JavaScript:

Minor additions: parse class with body, parse a suite of statement (a list of statement). One thing to review in this project and the previous one: Scala new line in lexer/parser. The language has special rules to skip or not a new line, depending on the context. I should add type checkting to this JavaScript project.


My Clojure interpreter in C#:

I applied a surgical refactor: internal reimplementation of top level context to save internally clojure vars. In this way, the top level definitions are saved not as name/value but as named var/value. The rest of the context are simple name/value dictionaries (like the context created by the special form let).


I created a new JavaScript/Node.js package:

a simple web scraper in JavaScript/Node.js. The initial commits only process HTML in text, iterating over tag items. Light weight, no dependencies needed yet.


I added minor changes to:

I worked on three non-public projects, too.

More fun is coming.

Keep tuned!

  4. It’s not as difficult as it appears to get your conventional IRA converted or to have your IRA rollover.
    That would mean the true rate of inflation is running 12%.
    In addition to that, it’s totally clear of any income taxes.

  5. First of all I would like to say terrific blog! I had a quick question which I’d like to ask if you do
    not mind. I was curious to find out how you center yourself and clear your head before writing.
    I’ve had a tough time clearing my thoughts in getting my ideas out there.
    I truly do enjoy writing however it just seems
    like the first 10 to 15 minutes are wasted simply
    just trying to figure out how to begin. Any recommendations or tips?

  7. Hey there! I just wanted to ask if you ever have any problems with hackers?
    My last blog (wordpress) was hacked and I ended up losing many months of hard work due to no backup.
    Do you have any solutions to stop hackers?

  15. When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is
    added I get three emails with the same comment. Is there
    any way you can remove me from that service? Thanks!
