Answer»
- Designed ground-up just for Java.
- Pure Java.
- Open-source freeware under LGPL; can be USE for commercial or any purposes.
- Is a 3GL and a 4GL.
- Hybrid procedural and object-oriented language.
- Basic data types include integer, floating-point number, date/time and string; each with large number of operations (methods).
- Advanced data structures:
array and linked list; flexible sorting and filtering
struct and ordered map; flexible sorting and filtering
stack and queue
tree
table data; in-memory relational database features
- Support advanced programming techniques:
user-defined classes and inheritance
exception handling and resume statement
thread programming similar to functions
user-defined functions; can TAKE variable number of parameters, and parameters can have default values
function variables and lambda functions
dynamic evaluation of code and files
flexible iterations of arrays and linked lists
- Java-like statements and expressions.
- Syntactic sugar, including various comment formats for Unix auto-run and code disabling.
- Seamless USES of Java classes, OBJECTS and arrays.
- Java collection classes share same syntax as Judo container data structures.
- Java static methods can be aliased to become Judo functions.
- Explicit JNDI support to facilitate RMI and EJB scripting.
- Is extensible by Java classes or by Judo libraries or a mixture of both. Library code can be moved from Judo into Java (LATER) without changing the interface.
- All existing Java software tool packages, commercial or free, can be used directly in Judo.
- Sophisticated JDBC scripting and database manipulation features.
- Many built-in application features; some with special syntax (hence 4GL), others are system functions. An incomplete list includes:
JDBC scripting
XML scripting
HTML/SGML scraping
Microsoft COM scripting
HTTP/HTTPS client and server
Schedule jobs with HTTP monitors
Flexible file copying and archiving between file systems, JAR, ZIP and TAR files
Consistent I/O model for local files, files within JAR/ZIP/TAR archives, gzipped files, internet resources and string data sources
FTP, SSH, SCP, networking services, Windows registry editing, Unix syslog
Encryption
Send mail
Versatile executable running
Java GUI creation
Text and data processing features
- Embeddable by Java software either by Bean-Scripting-Framework or via its own engine.
- Is interpreted. Precompilation is planned.
- Rich documentation for reference, tutorials and examples.
