LianjaScript and Python integration

Python is now the most popular programming language in the world.

LianjaScript is a data-centric scripting language specifically used for developing database applications. It is a modern day superset of Microsoft Visual FoxPRO which was widely praised for its speed and flexibility.

Lianja has complete two-way integration with Python. You can execute Python code directly from LianjaScript and execute LianjaScript code directly ...

The Lianja Script Editor is a full featured and modern source code editor. It includes support for syntax highlighting, intelligent code completion, code snippets, code folding, intellisense and Intellitips. Go beyond normal Intellisense with "Live" pick lists for cursors, parameter hints for all functions, function and variable discovery and much more.

Lianja provides the ability to build standalone executables on Windows.

This has been a popular request, so we have added in this functionality.

These executables can only be built for Apps that have been hand coded in LianjaScript, Python, JavaScript, TypeScript or Babel using the Lianja UI Framework.

This functionality is primarily for building small GUI Apps not for business Apps running under the Lianja App Center under the control of Permissions and Roles. ...

MetaTypes provide a powerful means of defining custom types and then subclassing them in Pages, Sections and FormItems.

Each MetaType that you define in the MetaType Editor can contain attribute/value pairs as well as delegates and their procedure or function names.

A MetaType is essentially a 'class' which can be inherited simply by specifying its name in the 'Meta Types' attribute for user interface elements. (Pages, Sections and FormItems).

Lianja Package Files (.lpk) are used to package up Apps, databases and Library files to transfer to another Lianja App Builder installation.
They can also be installed/updated automatically by the Lianja Cloud Server.

1. Build a package

You build a Lianja package file (.lpk) in the "Deploy" workspace.



Note: If you have a project open then the files contained within the project will already ...

Many developers have requested the ability to be able to build modern Web Apps in Lianja while running legacy VFP applications side by side accessing the same data.

Although this is possible using Lianja virtual tables with the VFP ODBC driver, OLEDB provides better performance and flexibility.

In Lianja 6.3 we have provided the ability to use OLEDB providers as an alternative means of transparent data access.

Let’s look at how we can integrate Lianja and ...

LianjaScript Modules are similar to libraries in that they can be dynamically loaded and contain procedures that may be used in your Apps.

Modules however encapsulate all procedures, functions and public variables and make these only visible from an object. This prevents name clashes and is a simple way to wrap code libraries into objects without any special coding syntax.

Modules provide simple (Object-Oriented Programming ) OOP concepts:

• Objects
• Abstraction
• Encapsulation
• Inheritance
• Polymorphism

There are many types of data queries in Lianja Apps. UI consistency is important for onboarding users with minimum training being needed. Providing powerful built-in data querying is an important requirement of a No-Code and Low-Code platform.

Action queries

An action query is a query that navigates between records using the ActionBar.



Instant Search

Instant Search allows the user to search the data on ...

Lianja 6.3 introduced a new Key/Value Store (KVS) to support data streaming and IoT applications.

A key-value database is a type of nonrelational database that uses a simple key-value method to store data. A key-value database stores data as a collection of key-value pairs in which a key serves as a unique identifier. Both keys and values can be anything, ranging from simple objects to complex compound objects.

KVS is implemented as a collection of functions built into ...
