Code Generation with AjGenesisNode

I updated and published new versions of my projects:

Now, there are new functions to manage the model directory in AjGenesis. That directory contains the JSON files that represent the model, ie entities, project settings, db settings, etc. It resides in “./ajgenesis/models”.

The code generation for Sinatra and Express was improved. Instead of create a project and then, generate a “build” subdirectory in project directory, now the code generation acts over the current project directory. This way is more straighforward, and more aligned with other projects that generates code: there is no “build” subdirectory.

I added the preserve of code regions by name. If a generated file has a code region delimited with special text, that region is preserved even when the file is regenerated.


My Dylan language interpreted in C#

I added more binary operations. I should add type support, but in the current use cases, the untyped evaluation is OK.


My Mule-like simple service bus in C#

I added message transformers, message processors, instead of play payload transformers and processors. And I added a Router object. So, the implementation has/will have:

- Lambdas that operates on payload (processors, transformers, outputs, routers)
- Lambdas that operatos on message (processors, transformers, outputs, routers)
- Objects that operates on payload (processors, transformers, outputs, routers)
- Objects that operates on messages (processors, transformers, outputs, routers)

A payload is an untyped object. A message has a payload and additional properties (by name/value).

JavaScript Samples

I wrote my first AngularJS samples

Dynamic Site in Express 4

Based on JSON definitions

I added the support of to load JSON files that have references to other JSON files. The site is a prototype based on pages defined in JSON files. So you can easy change the JSON data to alter the prototyped site. Next steps: add lists based on MongoDB collections, with views. Then, code generation for differents targets (Express 4? Laravel?)


I changed with minor improvements. I also worked on three non-public projects. More fun is coming.

Stay tuned!

Express Samples

I created the first version of

A dynamic site, using Express 4, EJS, and JSON file as site/pages definition format. Actually, only title and text are supported, but the idea is to define each site/subsite/page in JSON files. I will add list support (ie, tables with data) to be saved in MongoDB, and views (list rendered as tables/forms in HTML).


To support the load of JSON model from MANY files (to be used in the above DynSite4), I started:

A JSON file can refer to another one, and this small library load the full model from both.


My Dylan language interpreter in C#

I added the parse of simple expressions. I should add the type check of the expression. Maybe I will switch to many-phase parse: firts, build the AST (Abstract Syntax Tree), then check type, then generate expressions to be evaluated.


I updated the Node.js module

Now, it uses ./ajgenesis/models as local directory to load and save model.


I applied minor changes to (internal refactor), (fixing source analysis), (adding partial application). I worked on four non-public projects, too. More fun is coming.

Stay tuned!

Code Generation with AjGenesis

I published a new version of

My code generation tool, based on Node.js. Now, it can preserve files in generate tasks (if you want one of your files doesn’t overwritten). But the key change was to put models under current project directory, ajgenesis/models folder. In this way, I can put all the AjGenesis-related stuff in only one directory related to current project. So, I refactored and republished the modules and examples of:

Next steps: refactor to use the new directory, and refactor/complete the generation process in Express, Sinatra, Laravel, Django projects.


I worked on

implemented a simplified Mule-like message flow in C#, using TDD (Test-Driven Development). Now I have: input, output, transform, processors, routers, branches in flow. It was nice to see all in place, using “baby steps”, and the powerful lambdas of C#. I implemented transformer objects too. Next steps: instead of simply process a payload, start to process a complete message.


After attending a JavaScript meetup at Buenos Aires, I wrote a simple JavaScript curryfing function library:

Since then, I started to add some additional pieces, like partial application, and composition of functions.


Thanks to @fabiomaulo, I met state machine implementations in C#. So, I wrote my own version in JavaScript:

It has a fluent interface to define states, with triggers and actions. Next steps: add global triggers, and hierarchical states.


I added some functions to core and REPL. I worked on four private projects, too. More fun is comming.

Stay tuned!

My Go programming language interpreter in C#:

There are new nodes supported in parser. There are simple ones, but now the parser has a better coverage in order to implement simple use case. Next step: add some type checking, and generate commands and expression from parsed tree. I could generate commands and expression without type checking, as in an untyped interpreter. Or I could add type checking and generate the typed expression. In the first case, an add expression sums two objects. In the second case, an add expression sums two integers, or one integer and a float, or etc… In both cases, TDD helps me to implement the feature step by step.

PHP Samples and Laravel Code Generation

My scripts at:

I improved a bit my Laravel sample, using layouts, and now, Bootstrap for style. Laravel is a simple web framework, that I want to use in AjGenesis code generation for PHP. So, I updated:

too, to generate a seed site. Next steps: generate the Laravel model, migration, controllers from entity free model.


I added a simple figure to (a rectangle). So the API is in good shape, I published version 0.0.1 of I added some nodes to parser in I worked on two non-public projects, too. I started a sample accesing database, using Express version 4, at

Stay tuned!
