Generate code from Freemarker templates and JSON data with CSV support.
How to use it?
From terminal:
Download cli latest version and unzip it. From the root folder of application, you should see a folder structure similar to the following:
├── bin
│ └── cli
│ └── cli.bat
├── lib
│ └── ...
Execute according your operating system.
$ bin/cli \
--verbose \
--overwrite \
--read-recursive \
-d DATA_FOLDER \
-t TEMPLATES_FOLDER \
-o OUTPUT_FOLDER
From gradle script:
Create configuration:
configurations {
codegen
}
Declare dependencies:
dependencies {
codegen (
"io.github.h4j4x.codegen:cli:${latestVersion}",
"io.github.h4j4x.codegen:lib:${latestVersion}",
)
}
Create gradle task:
task codegen {
description = 'Generate code'
javaexec {
classpath = configurations.codegen
main = 'io.github.h4j4x.codegen.cli.CliApp'
args = [
'-d', "$projectDir/src/main/resources/data",
'-t', "$projectDir/src/main/resources/template",
'-o', "$projectDir/src/main/java",
]
}
}
Configuration
--verbose
Verbose mode (info, warning and error logs).
--overwrite
Overwrite mode (output files will replace existing ones).
--read-recursive
Data folder and sub-folders will be read for JSON files.
-d
Data folder for generation.
How to structure data?
Data must be specified in JSON files (.json) with following structure:
- With CSV (test.csv inside data folder).
{
"templates": [{
"template": "test.ftl",
"file": "folder/TestClass.java"
}],
"csvData": {
"csvKey": "items",
"dataKey": "data",
"fields": ["key", "description"],
"filePath": "test.csv",
"data": {
"generalConfig": "Some config"
}
}
}
- Without CSV.
{
"templates": [{
"template": "test.ftl",
"file": "folder/TestClass.java"
}],
"data": {
"key": "value"
}
}
-t
Templates folder for generation. Templates must be specified in FTL files (.ftl).
-o
Output folder for generation. Must be writable.
