In the process of reproduction, greate functions can be packaged as extensions to share. The following are the packaging standards for ZenTao Project Management Software.

1. Extensibles

Bin: newly added command-line scripts, etc;
Config: modifying configuration files, etc;
Db: install.sql and uninstall.sqldbcan be saved in the directory of ad, corresponding to sql scripts executed when installing and unloading plug-ins respectively;
Doc: documents related to extensions;
Lib: add a new class or modify the existing class;
Module: add a new module or extend existing modules
www: release your own styles or modify js file; 

2. Documents included in the directory of doc

Configuration of the extensions is included in the directory of doc and saved according to languages. For example, the English version is saved as en.yaml and the Chinese version as zh-cn.yaml. The configuration files of extensions are in the format of yaml, which include the basic information about the extensions and the release information about the previous builds

3. Files included in the directory of db

install.sql and uninstall.sql are included in the directory of db. install.sq is sql scripts executed when you install extensions and uninstall.sql is executed when you unload them. If your extensions involve changes to database, put corresponding sql scripts into the two files and ZenTao extension management program will automatically execute it.

4. Files included in the directory of module

Deploy the files in the directory of module according to extension mechanism.

5. Extension of the master configuration files

You may have to extend the configuration files globally in actual situation. In this case, put the extended configuration fils to the directory of zentao/config/ext/.

6. Install and delete hook scripts

If you have to do some actions before and after installing, and before and after unloading, create a directory for hook, then create preinstall.php, postinstall.php, preuninstall.php and postuninstall.php and save the code respectively.

7. Summary. Create your own extensions

7.1 Choose the English name for you extensions, such as hello;
7.2 Create a directory of hello;
7.3 Create the directory of doc in the directory of hello;
7.4 Create the configuration file of yaml in the directory of doc;

7.5 If any changes to database, you should create a directory of db in the directory of hello, and create install.sql and uninstall.sql in it. 

7.6 If you use hook scripts, create a directory of hook, and create preinstall.php, postinstall.php, preuninstall.php and postuninstall.php in it. 

7.7 Then deploy corresponding extension code. Create a directory of module in the directory of hello, and then put corresponding codes in it.

7.8 Pack and zip the entire directory of hello into hello.zip. It is completed.
