IndentPrinter (Groovy 4.0.24)

groovy.util.IndentPrinter

```
public class IndentPrinter
extends Object
```
A helper class for printing indented text. This can be used stand-alone or, more commonly, from Builders.
By default, a PrintWriter to System.out is used as the Writer, but it is possible to change the Writer by passing a new one as a constructor argument.
Indention by default is 2 characters but can be changed by passing a different value as a constructor argument.
The following is an example usage. Note that within a "with" block you need to specify a parameter name so that this.println is not called instead of IndentPrinter.println:
```
 new IndentPrinter(new PrintWriter(out)).with { p ->
     p.printIndent()
     p.println('parent1')
     p.incrementIndent()
     p.printIndent()
     p.println('child 1')
     p.printIndent()
     p.println('child 2')
     p.decrementIndent()
     p.printIndent()
     p.println('parent2')
     p.flush()
 }
 
```
The above example prints this to standard output:
```
 parent1
   child 1
   child 2
 parent2
 
```

Constructor Summary

Constructors
Constructor and description
`IndentPrinter()` Creates an IndentPrinter backed by a PrintWriter pointing to System.out, with an indent of two spaces.
`IndentPrinter(Writer out)` Creates an IndentPrinter backed by the supplied Writer, with an indent of two spaces.
`IndentPrinter(Writer out, String indent)` Creates an IndentPrinter backed by the supplied Writer, with a user-supplied String to be used for indenting.
`IndentPrinter(Writer out, String indent, boolean addNewlines)` Creates an IndentPrinter backed by the supplied Writer, with a user-supplied String to be used for indenting and the ability to override newline handling.
`IndentPrinter(Writer out, String indent, boolean addNewlines, boolean autoIndent)` Create an IndentPrinter to the given PrintWriter

- Constructor Detail
  - public IndentPrinter()
    
    Creates an IndentPrinter backed by a PrintWriter pointing to System.out, with an indent of two spaces.
    See Also:
    IndentPrinter(Writer, String)
  - public IndentPrinter(Writer out)
    
    Creates an IndentPrinter backed by the supplied Writer, with an indent of two spaces.
    Parameters:
    out - Writer to output to
    See Also:
    IndentPrinter(Writer, String)
  - public IndentPrinter(Writer out, String indent)
    
    Creates an IndentPrinter backed by the supplied Writer, with a user-supplied String to be used for indenting.
    Parameters:
    out - Writer to output to
    indent - character(s) used to indent each line
  - public IndentPrinter(Writer out, String indent, boolean addNewlines)
    
    Creates an IndentPrinter backed by the supplied Writer, with a user-supplied String to be used for indenting and the ability to override newline handling.
    Parameters:
    out - Writer to output to
    indent - character(s) used to indent each line
    addNewlines - set to false to gobble all new lines (default true)
  - public IndentPrinter(Writer out, String indent, boolean addNewlines, boolean autoIndent)
    
    Create an IndentPrinter to the given PrintWriter
    Parameters:
    out - Writer to output to
    indent - character(s) used to indent each line
    addNewlines - set to false to gobble all new lines (default true)
    autoIndent - set to true to make println() prepend the indent automatically (default false)
- Method Detail
  - public void decrementIndent()
  - public void flush()
  - public boolean getAutoIndent()
  - public int getIndentLevel()
  - public void incrementIndent()
  - public void print(String text)
    
    Prints a string.
    Parameters:
    text - String to be written
  - public void print(char c)
    
    Prints a character.
    Parameters:
    c - char to be written
  - public void printIndent()
    
    Prints the current indent level.
  - public void println(String text)
    
    Prints a string followed by an end of line character.
    Parameters:
    text - String to be written
  - public void println()
    
    Prints an end-of-line character (if enabled via addNewLines property). Defaults to outputting a single '\n' character but by using a custom Writer, e.g. PlatformLineWriter, you can get platform-specific end-of-line characters.
