Subject [jira] Closed: (LANG-498) Add StringEscapeUtils.escapeText() methods
Date Tue, 30 Jun 2009 07:08:47 GMT

     [ https://issues.apache.org/jira/browse/LANG-498?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Henri Yandell closed LANG-498.
------------------------------

    Resolution: Fixed

UnicodeEscaper.outsideOf(32, 0x7f) now works and would handle this case. Or if you want >=
7f, use 0x7e. 

There is also a EscapeUtils.ESCAPE_JAVA_CTRL_CHARS and matching unescape. So your request
is (currently anyway in trunk):

{code:java}
new AggregateTranslator(
            EscapeUtils.ESCAPE_JAVA_CTRL_CHARS,
            UnicodeEscaper.outsideOf(32, 0x7f)
        );
{code}

or:

{code:java}
EscapeUtils.ESCAPE_JAVA_CTRL_CHARS.with( UnicodeEscaper.outsideOf(32, 0x7f) )
{code}

I'm resolving this issue as I think this sufficiently simplifies your desire to share the
escapeJava code.

> I needed to escape text to be print out to a file; mainly so that all non-ASCII characters
(< 32 and >=127) are printed out as escapes (if available) or unicode escapes. This
is a one-way conversion, there is no way to find out whether a String contained "\\n" or a
newline before conversion, so I just set up escapeText() methods, no unescapeText(). 
> Please apply to the next release of commons-lang. :-)
