To clarify, #printToFileNamed: and company use CRLF on Windows and LF 
elsewhere. XMLWriter uses Pharo's LE by default (CR), but it will use the 
preferred LE of your platform (LF or CRLF) with 
#enablePlatformSpecificLineBreak, LF when canonical XML 
(https://www.w3.org/TR/xml-c14n) is enabled, or whatever LE you want with 
#lineBreak:.

You can use #printToFileNamed:beforeWritingDo: with a block that sends 
#lineBreak: to the writer argument to get a custom LE when printing a DOM tree 
to a file.

[Pharo-users] Pharo 7 license question

[Jimmie Houchin]

Hello,

Pharo 7 to my understanding fundamentally changes Pharo. It is my 
understanding that Pharo 7 starts with a core Pharo kernel and like many 
languages out there, imports or adds code from a variety of external 
sources to the image being built.


With that understanding, I am curious if that would allow for inclusion 
of a specific library/module to be licensed as GPL? And it not affect 
the other code in the composed image?


I am a big believer in the MIT/BSD license and not a big fan of the GPL. 
However, there is software out there that I have avoided looking at the 
source code or attempting to port it to Pharo because it is GPL. I would 
sincerely love if I could now port such a library and license it under 
the GPL as required, and it not affect any other code outside of that 
specific library.


I am not a lawyer. Nor do I know any lawyers. Is is possible for someone 
to get a reasonably definitive answer on this question?


I am sure I am not the only one who has had this desire. I am also sure 
that I am not the only one who will have this question in the future. So 
it would be nice to have a proper legal response that could possibly be 
explicitly stated somewhere on the website or on an FAQ or something.


Regardless of the answer, yes or no. It does need to be a settled issue 
for Pharo. That way someone could know if GPL/LGPL or whatever software 
could be in the catalog.


Just wanted to put that out there to the community. I look forward to 
the answer, should one be or become available.


Thanks.


Jimmie

Re: [Pharo-users] Writing XML

[Jimmie Houchin]

I didn't pay attention to this previously. But I just noticed that using 
#printToFileNamed:   preserved the DOM tree's original line ending where 
as previously I had to insure the the XMLWriter #lineEnding was changed 
from defaultLineEnding to canonicalLineEnding. The original document 
used LF and not CR.


Overall this was a nice win.
It cleaned up my method to save the file and reduced 7 lines to 2.
Nice.  :)

Thanks.

Subject: [Pharo-users] Writing XML

Hello,

I am attempting to read and write an XML document.

Currently I have parsed the document successfully. I have basic
navigation and have learned how to modify the XMLDocument.

Now I want to write the modified document back to the file system.
What I have tried so far is:

writer := XMLWriter new.
xmldoc document writeXMLOn: writer.
writer stream.
f := File openForWriteFileNamed: '/home/jimmie/xmldoc.xml'.
f nextPutAll: (writer write contents).
f flush.
f close.

It does write an xml document to the file system. However, it has
exploded in size. The original is 28mb and is in UTF-8. The newly
written file is 112mb and is UTF-32.

I do not know why the change in encoding or how to correct or manually
set the encoding.

Any help in understanding how to correctly write an XML document that I
have read and minimally modified would be greatly appreciated.

Thanks.

Jimmie

[Jimmie Houchin]

Thanks for the reply.
I appreciate the education the people on this list provide.

I was already doing the XMLDOMParser #onFileNamed: to open the file.
It was showing the correct #encoding for the parsed file.
It was just the writing of the nearly identical file which was different.
I tried as you wrote #printToFileNamed:and it did as you explained.

Thanks again.

Jimmie

Re: [Pharo-users] Usability issues with Calypso

[kmo]

You say The current behaviour is trying to be close to single source pane
behaviour of old browsers. 

I think that's a bit of the problem. For me, nautilus is a single source
pane browser and it looks like a single source pane browser. Calypso looks
like something else - it looks like a typical tabbed editor. So it's
behaviour does not march its look. That's what's confusing.

I don't know what is the best behaviour for the tabs - but I think I would
prefer always manually opening/closing tabs rather than the auto tabs
behaviour - that way I would feel more in control.

Other people's mileage may vary.

Re: [Pharo-users] Writing XML

[monty]

If you want to write a DOM tree to a file, send #printToFileNamed: (or a 
related message like #canonicallyPrintToFileNamed: or 
#printToFileNamed:beforeWritingDo:) to the root. See the XMLNode "printing" 
category for more. This will automatically encode the file with the encoding 
the XMLDocument>>#encoding attribute specifies (if recognized), and it's 
portable across Pharo, Squeak, and GemStone. Use #parseFileNamed:/#onFileNamed: 
to get portable automatic file decoding when parsing.
