| <h2><a name="fixcrlf">FixCRLF</a></h2> |
| <h3>Description</h3> |
| <p> |
| Adjusts a text file to local conventions. |
| </p> |
| |
| <p> |
| The set of files to be adjusted can be refined with the |
| <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, |
| <i>excludesfile</i> and <i>defaultexcludes</i> |
| attributes. Patterns provided through the <i>includes</i> or |
| <i>includesfile</i> attributes specify files to be |
| included. Patterns provided through the <i>exclude</i> or |
| <i>excludesfile</i> attribute specify files to be |
| excluded. Additionally, default exclusions can be specified with |
| the <i>defaultexcludes</i> attribute. See the section on <a |
| href="../dirtasks.html#directorybasedtasks">directory based |
| tasks</a>, for details of file inclusion/exclusion patterns |
| and their usage. |
| </p> |
| |
| <p>This task forms an implicit <a href="../CoreTypes/fileset.html">FileSet</a> and |
| supports all attributes of <code><fileset></code> |
| (<code>dir</code> becomes <code>srcdir</code>) as well as the nested |
| <code><include></code>, <code><exclude></code> and |
| <code><patternset></code> elements.</p> |
| |
| <p> |
| The output file is only written if it is a new file, or if it |
| differs from the existing file. This prevents spurious |
| rebuilds based on unchanged files which have been regenerated |
| by this task. |
| </p> |

| <td valign="top"> |
| Specifies how end-of-line (EOL) characters are to be |
| handled. The EOL characters are CR, LF and the pair CRLF. |
| Valid values for this property are: |
| <ul> |
| <li>asis: leave EOL characters alone</li> |
| <li>cr: convert all EOLs to a single CR</li> |
| <li>lf: convert all EOLs to a single LF</li> |
| <li>crlf: convert all EOLs to the pair CRLF</li> |
| </ul> |
| Default is based on the platform on which you are running |
| this task. For Unix platforms, the default is "lf". |
| For DOS based systems (including Windows), the default is |
| "crlf". For Mac OS, the default is "cr". |
| <p> |
| This is the preferred method for specifying EOL. The |
| "<i><b>cr</b></i>" attribute (see below) is |
| now deprecated. |
| </p> |
| <p> |
| <i>N.B.</i>: One special case is recognized. The three |
| characters CR-CR-LF are regarded as a single EOL. |
| Unless this property is specified as "asis", |
| this sequence will be converted into the specified EOL |
| type. |

| Used only in association with the |

| <h3>Examples</h3> |
| <pre> <fixcrlf srcdir="${src}" |
| eol="lf" eof="remove" |
| includes="**/*.sh" |
| /></pre> |
| <p>Replaces EOLs with LF characters and removes eof characters from |
| the shell scripts. Tabs and spaces are left as is.</p> |
| <pre> <fixcrlf srcdir="${src}" |
| eol="crlf" |
| includes="**/*.bat" |
| /></pre> |
| <p>Replaces all EOLs with cr-lf pairs in the batch files. |
| 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.</p> |
| <pre> <fixcrlf srcdir="${src}" |
| tabs="add" |
| includes="**/Makefile" |
| /></pre> |
| <p>Sets EOLs according to local OS conventions, and |
| converts sequences of spaces and tabs to the minimal set of spaces and |
| tabs which will maintain spacing within the line. Tabs are |
| set at 8 character intervals. EOF characters are left alone if |
| run on DOS systems, and are removed if run on Unix systems. |
| Many versions of make require tabs prior to commands.</p> |
| <pre> <fixcrlf srcdir="${src}" |
| tabs="remove" |
| tablength="3" |
| eol="lf" |
| javafiles="yes" |
| includes="**/*.java" |
| /></pre> |
| <p> |
| Converts all EOLs in the included java source files to a |
| single LF. Replace all TAB characters except those in string |
| or character constants with spaces, assuming a tab width of 3. |
| If run on a unix system, any CTRL-Z EOF characters at the end |
| of the file are removed. On DOS/Windows, any such EOF |
| characters will be left untouched. |
| </p> |
| <pre> <fixcrlf srcdir="${src}" |
| tabs="remove" |
| includes="**/README*" |
| /></pre> |
| <p>Sets EOLs according to local OS conventions, and |
| converts all tabs to spaces, assuming a tab width of 8. |
| 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.</p> |
