xml sgml & psgml

xml sgml & psgml

[Adam Hardy]

Hi All,

I'm editing some xml files and I am having a few problems. I installed 
the latest version of psgml from sourceforge and put some config code in 
my .emacs but I am unable to get indentation to work.

I also put the latest version of sgml.el in my lisp directory because I 
read on the archives here that it enables indents.

I'm not the world's most experienced lisp programmer so I'm not sure 
about the following:

does psgml disable the functionality in sgml.el or build on it ?

does the sgml.el code get loaded alright or do I have to do that in my 
.emacs ?

how can I tell whether I'm using psgml or just sgml code?

Can anyone help?

TIA
Adam

Often, it helps to (setq sgml-indent-data t), but you don't give
enough information to see whether it will help.

I don't have that in my .emacs - but adding it makes it work.  I don't 
suppose it's got electric support?

How did you find out about that? I found what I found through searching 
with google.  Reading the lisp code was too difficult at my level of 
understanding to serve as documentation.

To answer another of my original questions, would the following .emacs 
config enable psgml? And can I do anything to test whether this psgml is 
enabled?

Great.

Non sequitur?  What's "it"?  What do you mean by electric?

I highly recommend reading the documentation :-)

For example, C-h v sgml- TAB TAB gives you a list of related
variables, choosing one of them with completion will show you the
documentation for that variable.

Also, psgml has an info file which describes lots of stuff.  Just hit
C-h i d, then look for the PSGML line.  (If you have installed it
correctly.)

The config looks okay (except for the load-path frobbing which looks
really weird).  You can look in the menu bar, if there are menu items
Markup, SGML, and DTD, then you should be fine.

electric characters are particular characters which cause indentation to 
happen as soon as you type them, ie. < or / or >

This is in C and Java mode.

excellent. Just what I was looking for. Never had a clue it was there!

load-path frobbing? What's frobbing? Sounds like hitting it with a dead 
rabbit!

Ah, now I understand.  No, I don't think that psgml is electric.
You'd have to do that yourself.  But it should be fairly simple.  How
about sharing the results?  Post psgml-electric.el to
gnu.emacs.sources :-)

No that's like waving dead chickens.

You will notice that Lisp itself is not that difficult.  Just spend
the time to learn it -- it's a small language, like C.

It's the library functions that make it difficult.  But luckily, you
can learn those in an on-demand fashion and don't need to have a
complete overview of those.
