Ignore Transformation

The ignore transformation in Codefend enables you to exclude specific words from being obfuscated. These words, once identified by the parser, are ignored and not obfuscated.

Use Cases:

In case the _ or - was in the variable name or the value of:

1. Environment variables

2. API keys and credentials

3. Constants

4. External variables of a dependency that would break if changed

5. Specific folder names, function names, class names, or critical elements of external libraries could lead to errors during the project's execution or building process. Visit troubleshooting section for more info.

// .codefendrc.json
{
  //...
  "transformation": {
    "ignore": ["l_variable1"]
    //...
  }
}

For example:

l_variable1 = l_variable2 + l_variable3

Gets transformed to:

l_variable1  = Ox1 + Ox2

TIP

In this example, notice how l_variable1 has been ignored and kept as is, while the other detected variables have been transformed using the default transformation.

TIP

The words of the ignore array must be detected by the parser, so they should follow the naming convention specified in the configuration.

The same transformation is applied to the Folders and File names, For example:

// .codefendrc.json
{
  //...
  "transformation": {
    "ignore": ["node_modules"]
    //...
  }
}

├── pkg-src
│   ├── pkg-controller
│   │   ├── file-user-controller.js
└── node_modules

Gets transformed to:

├── Ox0
│   ├── Ox1
│   │   ├── Ox2.js
└── node_modules

TIP

In the previous example, pay attention to the file name node_modules. Although it follows the naming convention of the code rather than typical file naming, there's no need to worry. Codefend will handle it just like any other variable detected, using the specified naming convention for obfuscation, even if it originally referred to a file name instead of a word within the code.
