Manifest: CTRL-F does not format long lines [message #524971]

Hello,

I want to format my MANIFEST.MF file, which contains a very long

Service-Component: OSGI-INF/Service0.xml, OSGI-INF/Service1.xml, OSGI-INF/Service2.xml

line.

* Is this a feature or a bug? (because Service-Component lines will not be formatted?)
* The error message says "This line is to long". How long could a MANIFEST.Mf line be? this would be
interesting, because I do not know and I have to format it on my own.

If it is a bug, where could I file it -- there are a lot of products, components in the bugzilla

Regards,

Jens

Hi Jens,

The JAR File spec
http://java.sun.com/j2se/1.4.2/docs/guide/jar/jar.html#JAR%2 0Manifest
states:

------------------------------------------------------------ ------------
* Line length:

No line may be longer than 72 bytes (not characters), in its UTF8-encoded form. If
a value would make the initial line longer than this, it should be continued on extra
lines (each starting with a single SPACE).
------------------------------------------------------------ --------------

> * Is this a feature or a bug? (because Service-Component lines will not be formatted?)

The Eclipse Manifest editor has no formatter. I also don't get a warning/error about long
lines. But when a bundle is exported, the MANIFEST.MF is properly formatted and long lines
are wrapped. Bugs for the manifest editor belong to PDE / UI.

Greetings,

Ralf

Hi again,

> The Eclipse Manifest editor has no formatter.

sorry, this should have been "the formatter for the eclipse manifest editor doesn't do
line wrapping".

Greetings,
Ralf

Hello Ralf,

it does some kind of line wrapping. E.g. one line with

Import-Package: de.kue.osgi.scr2.a,org.osgi.framework;version="1.3.0",
org.osgi.service.component;version="1.1.0"

is changed into

Import-Package: de.kue.osgi.scr2.a,
org.osgi.framework;version="1.3.0",
org.osgi.service.component;version="1.1.0"

This is, what I expected for the "Service-Component:"

By the way it looks like the error show up if a line is longer than 500 characters. This is quiet a
little bit more than the 72 bytes ;).

Regards,
Jens
