Zserio Extension Sample

---

Sample implementation of Zserio extension.

This extension prints all AST (Abstract Syntax Tree) nodes to the terminal. The extension can be invoked by command line option -sample.

Example

Using the schema

package simple_structure;

struct SimpleStructure
{
    int32  numberA;
    uint8  numberB;
    string name;
}

gives Zserio compiler together with this Zserio extension sample the following output:

Parsing simple_structure.zs
Calling Sample extension check
Calling Sample extension
  package simple_structure
    structure SimpleStructure
      int32 numberA
      uint8 numberB
      string name
Done

Prerequisites

1. Java SDK
2. Apache Ant
3. Zserio core (zserio_core.jar) together with dependent libraries.

Zserio core with dependent libraries will be automatically downloaded from GitHub according to the extension version located in the module SampleExtension.java.

Build

ant install

Run

java -cp build/download/zserio_libs/zserio_core.jar:distr/zserio_sample.jar \
    zserio.tools.ZserioTool simple_structure.zs -sample

To simplify the command for running the extension, ensure that zserio_sample.jar is in the same directory as zserio_core.jar. Once copied, you can use the following command:

java -jar zserio_core.jar simple_structure.zs -sample

Bundled Zserio

There is a sample implementation of bundled Zserio which will contain all extensions found in the original bundled Zserio together with the extension sample.

Build

ant zserio_bundle.install

Run

java -jar distr/zserio.jar simple_structure.zs -sample
