VirtualView Tools

中文文档

This project is a tool library as a part of VirtualView library, used to compile XML files:

How-to

Run From CMD

Tools Introduction

Download the source code, the executable is located at folder TemplateWorkSpace. There are several files here:

File	Introduction
config.properties	configs of widget's ID and attribute's value type
templatelist.properties	the file list of XML template
build	output folder after compiling XML files
template	the source code XML files
compiler.jar	executable jar file exported from the total source code
buildTemplate.sh	the command script to run compiler.jar

How to Run

Execute the follow command in Terminal: sh buildTemplate.sh
The artifacts is located at folder build

How to Configure `config.properties`

VIEW_ID_XXXX
- Define the widget's id, User's custom widget's should start from 1000;
- For example, VIEW_ID_FrameLayout=1 means the tag <FrameLayout> in XML will be compiled to number 1;
- The property name in should start with VIEW_ID_; - Widget's Id value from 1 t0 1000 are reserved for system, so custom widget's id should be assigned start 1001;
property=ValueType
- Define the attribute's value type, which decide how to parse and compile original value into a compiled data in.
- Currently supported defination is:
  - Normal type：String(Default, no need configuration)、Float、Color、Expr、Number、Int、Bool
  - Special type: Flag、Type、Align、LayoutWidthHeight、TextStyle、DataMode、Visibility
  - Enum type: Enum<name:value,……>
    - Enum desp：
      - For example: flexDirection=Enum<row:0,row-reverse:1,column:2,column-reverse:3>
      - This means the attribute row will be converted into number 0, and row-reverse into number 1

How to Configure `templatelist.properties`

Format: xmlFileName=outFileName,Version[,platform]
- xmlFileName； The file name need to be compiled under folder template, no need to add file extension here;
- outFileName: The output file name after compiling;
- Version: XML file's version;
- platform: Optional, valid value are android and iphone. Used to describe which platform current XML is target to, the output artifacts will be stored at a separate folder;

How to Write XML

The same way as before, while no need to write Java code to process new attributes, the only thing need to do is add a ValueType defination in config.properties;

Artifacts after Compiling

File under folder out: the binary data serialized from template file, all the other three outputs are generated from this.
File under folder java: the binary data in form of Java byte array. May be copied to Android project to run.
File udner folder sign: the md5 of binary data;
File under folder txt: the binary data in form of HEX string.

Use as API

Except that use as a command tool to compile file, there is an another way to compile XML data from an IDE plugin, a client, a backend service or somewhere else. So it's possible to use JAVA API to compile data, the example code is as follow:

//Build a ViewCompilerApi instance
ViewCompilerApi viewCompiler = new ViewCompilerApi();
//init a ConfigLoader to load config.properties.
viewCompiler.setConfigLoader(new LocalConfigLoader());
//read XML data from file or somewhere else
FileInputStream fis = new FileInputStream(rootDir);
//Parameters are XML data's InputStream, template name, template version
byte[] result = viewCompiler.compile(fis, "icon", 13);
