There are three code generator types written using the same mechanism:

JPortal

A generator that generates DALs (Data Access Layers) for various databases (Oracle, MS SQL Server, Postgres, SQLLite, DB2) in various languages (C#, Java, C++, Python, VB).

Crackle

A generator that generates IDL (Interface Definition Language) RPCs (Remote Procedure Calls) using Client/Server for various languages.

Pickle

A generator that generates Parameter Control Table maintenace code. A front end written in C# that maintains any ADO.NET Database.

This mechanism or paradigm follow the same coding pattern. There is a parser generator or compiler compiler written using javacc for the tokenising and grammar parsing. Each defines a domain specific language with some crossover capabilities. These generators are written in plain old java and they are maintained in Eclipse, but any text editor and javac would suffice to maintain them. They produce a generic class network database. They use public members and are not getter setter based classes. They also have a minimum of methods. They produce a tree structure of the compiled source.

The compiled tree then is available to be used by generators to compile code to be used by any computer language, current or future. This system has been used for many projects and applications over the last 20 years, very successfully. It used to be Java 1.1 based as there were ide's written in C# to maintain code. Dropping the ide usage and the need for J# has freed up this restriction.

See Building JPortal below.

This project now includes a vagrant file to simplify the building process To use vagrant, first install the vagrant tool for your platform from https://www.vagrantup.com/downloads.html Then, from a command shell (windows or linux) run the following commands:

user@localmachine:~/jportal> vagrant up 
user@localmachine:~/jportal> vagrant ssh 

The vagrant up command will take a while, as it will download a Linux VM to run the compile in, and it will then install all the required tools.

vagrant ssh will let you SSH into the newly created and running VM.

Once you are ssh'ed into the vm, issue the following commans to build the generators:

vagrant@vagrant:~$ cd /main/jportal/
vagrant@vagrant:~$ mkdir build && cd build
vagrant@vagrant:~$ cmake ..
vagrant@vagrant:~$ make

That will build the generators, and place the jar files in /main/jportal/generators/bin.

If you just want to build jportal, you can issue

vagrant@vagrant:~$ make target_jportal_jar

or

vagrant@vagrant:~$ make help

to see all possible build targets.

Lastly you can use

vagrant@vagrant:~$ make VERBOSE=1 [<target>]

for debug info.

To stop the VM once you are done, you can issue:

user@localmachine:~/jportal> vagrant halt

Assuming the repository has been checked out to /main/jportal. The cmake is used from /main/jportal/build, build is in .gitignore so initially one must do a 'mkdir' of it and from it do a 'cmake ..'. Once the cmake has been made and as long as all the required tools are in place, 'make' should complete an initial build.

There is a wrinkle - the current source is /main/jportal based on windows c:\main\jportal - this is not a cmake problem, but in the anydbmake having /main/jportal hardcoded - I will look into fixing this - but using c:\main\jportal should suffice for now. A stategic use of mklink /J should solve most problems.

I am running on linux mint 17.3 Rosa, which is debian based. Installing oracle client software is quite trial and error. But I do now have the client connecting to the Developer Days stuff. Of course we use sudo alien -i ... to install the instantclient stuff. The linux mint is a superb desktop environment, IMNSHO it is the route Microsoft should have gone, but when you business model is Total Resale every 3-5 years, more the pity.

I have quite good success on a Windows 7 VM - I am not using Visual Studio for the cmake, but using mingw - using unix build - I am also using git bash for the make terminal.
