Text to String literal conversion

In connection with writing some unit tests, I need a utility to convert
text output to a String constant expression.

http://www.snible.org/java2/uni2java.html is almost exactly what I want,
but I would prefer the literals broken at newlines and concatenated.
That is:

aaa\bbb
kkk


gets converted to "aaa\\bbb\nkkk\n". I would prefer:

"aaa\\bbb\n" +
"kkk\n"

This seems like a wheel that should already exist, so I would rather not
invent it myself.

freemarker.template.utility.StringUtil
Should get you as close as the above mentioned.

loop through char by char and if the char gets any special treatment
replace it with something

String s = "hi\n\\kkk"; //hi
//\kkk

StringBuilder b = new StringBuilder();
for(char c : s.toCharArray())
{
switch(c)
{
case '\n':b.append("\\n");break;
case '\r':b.append("\\r");break;
case '\':b.append("\\\\")break;
case '\"':b.append("\\\"");break;
case ''':b.append("\\'");break;
//Add in whatever else
default:b.append(c);
}
}

see the code in http://mindprod.com/applet/quoter.html
you can change it to suit yourself.

Roedy: This utility is quite comprehensive, but it may be a challenge to
modify: the common13, csv, ledatastream and hunkio directories appear to
be missing:-) Any pointers?

all those packages are available to download.  see
http://mindprod.com/products.html

But if you want to just cannibalise the code to create string
literals, you need only one class in the bundle, namely
ToJavaStringLiteral.java

I have corrected the zip to include common13.  It did not used to need
it. I converted it from AWT to Swing recently, which now uses it.

Quoter does not use csv, ledatastream or hunkio.  It does not even
mention them in comments.  Have you  Quoter with some other
program?  Maybe fileio?

Thanks! The new source <http://mindprod.com/zips/quoter41.zip> builds
correctly; it contains the common13 directory, as imported in lines
83-85 of Quoter.java:

import com.mindprod.common13.CMPAboutJBox;
import com.mindprod.common13.HybridJ;
import com.mindprod.common13.JEButton;

I was confounding common11.CMPAboutBox & common13.CMPAboutJBox.

The others (csv, ledatastream or hunkio) are imported by unused classes.
For example, the class ImageInfo imports LEDataInputStream. Here are the
dependencies I found:

./com/mindprod/common11/ImageInfo.java:
import com.mindprod.ledatastream.LEDataInputStream;
./com/mindprod/entities/GenCheat.java:
import com.mindprod.csv.CSVReader;
./com/mindprod/entities/InsertFileEntities.java:
import com.mindprod.hunkio.HunkIO;
./com/mindprod/entities/StripFileEntities.java:
import com.mindprod.hunkio.HunkIO;

I was tracking down a problem with the applet occasionally losing
clipboard access in Safari; the application works fine.

arrgh.  This means you need those packages just to do the build, even
though you never use those classes.

I have updated the ANT scripts to include ledatastream all the time
and csv and hunkio whenever entities is used. I will post within the
hour.

I wonder what sort of tool I could concoct to make sure my zips are
complete.

I found GenJar to make sure the jar is complete without excess fat.

I was thinking of writing a tool to make sure everything in the jar
was in the zip, but that is nowhere near sufficient.

This was not my experience using javac; after deleting all the class
files, the sources compiled with a few warnings and main executed
correctly. (Absent an E: drive, I can't use your build.xml file:-)

The new zip compiles correctly. Although the web site still shows the
last update as "2008-02-09", the zip is indeed new.

Would ant's depend task be of use? With some restrictions, it appears to
determine dependencies based on references in the class files themselves:

use the simpler rebuild.xml file.  All you need do is modify this one
line.
<project name="common13" basedir="E:/" default="jar">
to change that E:

More detailed instructions willl appear on the website within the
hour.
