## FixCRLF

### Description

Adjusts a text file to local.

It is possible to refine the set of files that are being adjusted. This can be done with the includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks, on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of `<fileset>` (`dir` becomes `srcdir`) as well as the nested `<include>`, `<exclude>` and `<patternset>` elements.

### Parameters

Attribute | Description | Required
srcDir | Where to find the files to be fixed up. | Yes
destDir | Where to place the corrected files. Defaults to srcDir (replacing the original file) | No
includes | comma separated list of patterns of files that must be included. All files are included when omitted. | No
includesfile | the name of a file. Each line of this file is taken to be an include pattern | No
excludes | comma separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. | No
excludesfile | the name of a file. Each line of this file is taken to be an exclude pattern | No
defaultexcludes | indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted. | No
cr | Specifies how carriage return (CR) characters are to be handled. Valid values for this property are: add: ensure that there is a CR before every LF asis: leave CR characters alone remove: remove all CR characters Default is based on the platform on which you are running this task. For Unix platforms, the default is remove. For DOS based systems (including Windows), the default is add. Note: Unless this property is specified as "asis", extra CR characters which do not precede a LF will be removed. | No
tab | Specifies how tab characters are to be handled. Valid values for this property are: add: convert sequences of spaces which span a tab stop to tabs asis: leave tab and space characters alone remove: convert tabs to spaces Default for this parameter is "asis". Note: Unless this property is specified as "asis", extra spaces and tabs after the last non-whitespace character on the line will be removed. | No
tablength | The number of characters a TAB stop corresponds to. Must be a positive power of 2, default for this parameter is 8. | No
eof | Specifies how DOS end of file (control-Z) characters are to be handled. Valid values for this property are: add: ensure that there is an EOF character at the end of the file asis: leave EOF characters alone remove: remove any EOF character found at the end Default is based on the platform on which you are running this task. For Unix platforms, the default is remove. For DOS based systems (including Windows), the default is asis. | No

### Examples

      <fixcrlf srcdir="${src}"
           cr="remove" eof="remove"
           includes="**/*.sh"
      />

Removes carriage return and eof characters from the shell scripts. Tabs and spaces are left as is.

      <fixcrlf srcdir="${src}"
           cr="add"
           includes="**/*.bat"
      />

Ensures that there are carriage return characters prior to evey line feed. Tabs and spaces are left as is. EOF characters are left alone if run on DOS systems, and are removed if run on Unix systems.

      <fixcrlf srcdir="${src}"
           tabs="add"
           includes="**/Makefile"
      />

Adds or removes CR characters to match local OS conventions, and converts spaces to tabs when appropriate. EOF characters are left alone if run on DOS systems, and are removed if run on Unix systems. Many versions of make require tabs prior to commands.

      <fixcrlf srcdir="${src}"
           tabs="remove"
           includes="**/README*"
      />

Adds or removes CR characters to match local OS conventions, and converts all tabs to spaces. EOF characters are left alone if run on DOS systems, and are removed if run on Unix systems. You never know what editor a user will use to browse README's.
