Hi,
I have made a new test version of org.el with quite significant
changes. Maybe there are a few people with some time to test things?
The file is here:
http://www.astro.uva.nl/~dominik/Tools/org/org-4.19a.zip
The new features are already documented in org.pdf, please check the
sections 3.2, 4.1, and the first two entries in 10.7.
New link format and display
===========================
What I have done is to follow Scott's request (thanks for pushing me
to implement this) and implemented an emacs-wiki compatible
link-hiding scheme. That means you can write links like
[[internal text search]]
[[internal text search][descriptive text]
[[<http:www.google.com]]
[[<http:www.google.com][Google search]]
Font-lock in Org-mode will then make sure that only the link or only
the descriptive text is shown in the buffer. The brackets and (if a
description is present) the link itself will be still in the buffer,
but invisible. This goes a long way to clean up the view of an
Org-mode buffer, because some links, in particular those containing
message-ids or search parameters look noisy.
The command C-c C-l will prompt for a description when inserting a
link. If you use it to insert a link stored with C-c l in another
buffer (for example a link to an email), then the descriptive text
will default to something extracted from the context of the link. For
this I had to modify the mail interfaces, and it is possible that I
introduced a bug somewhere, please check.
Narrowing table columns
=======================
So this was a lot of fun. Unfortunately, it messed up table
alignment, because invisible characters are not treated by
`string-width'. So I had to fix the table alignment to do this, and
this gave me an opportunity to finally implement something I wanted to
have for a long time.
Sometimes in tables, I need in one or a few fields more information
than usual, for example a number with some explanation. This was
problematic with org-mode tables, because it would mean that the
corresponding column would become very wide indeed, and the table
more-or-less useless. So I wanted to be able to limit the width of a
column, while still having a lot of text in it. This is now possible.
If any field in a column contains nothing but "<10>", than that column
is not permitted to become wider than 10 characters.
Wide fields are clipped for display (by making characters invisible).
You can see the full field in a tooltip window when holding the mouse
over the field. You can edit such a field in a separate window with
C-c ` (C-c followed by backquote). Finish with C-c C-c after
editing.
So far this seems to work well for my test cases, but I am quite sure
that there may be problems with character sets where not every
character is a single column wide. However, tables without links and
narrowing should still work fine for such character sets.
Oh yes, narrowing does not work in XEmacs, because the `format'
function in XEmacs does remove text properties. I could work around
this, but this was way too much for now.
Other changes
=============
- Links have now a new link face, which is underlined.
- Tags are bold-face, but in the same color as the headline.
I hope you have as much fun trying this out as I had implementing it.
- Carsten
