Class FileNameCompletor

java.lang.Object
  jline.FileNameCompletor

All Implemented Interfaces:

Completor

public class FileNameCompletor
extends Object
implements Completor

A file name completor takes the buffer and issues a list of potential completions.

This completor tries to behave as similar as possible to bash's file name completion (using GNU readline) with the following exceptions:

• Candidates that are directories will end with "/"
• Wildcard regular expressions are not evaluated or replaced
• The "~" character can be used to represent the user's home, but it cannot complete to other users' homes, since java does not provide any way of determining that easily

TODO

• Handle files with spaces in them
• Have an option for file type color highlighting

Method Detail

complete

public int complete(String buf,
                    int cursor,
                    List candidates)

Description copied from interface: Completor

Populates candidates with a list of possible completions for the buffer. The candidates list will not be sorted before being displayed to the user: thus, the complete method should sort the List before returning.

Specified by:

complete in interface Completor

Parameters:

buf - the buffer

candidates - the List of candidates to populate

Returns:

the index of the buffer for which the completion will be relative

matchFiles

public int matchFiles(String buffer,
                      String translated,
                      File[] entries,
                      List candidates)

Match the specified buffer to the array of entries and enter the matches into the list of candidates. This method can be overridden in a subclass that wants to do more sophisticated file name completion.

Parameters:

buffer - the untranslated buffer

translated - the buffer with common characters replaced

entries - the list of files to match

candidates - the list of candidates to populate

Returns:

the offset of the match
