suggestion: display of #+TITLE

suggestion: display of #+TITLE

[Dan Davison]

Might it be worth considering a special display for the #+title line in
org buffers?

Currently it is easy for the title to get buried among more technical
configuration lines like #+options, #+startup, #+seq_toto etc. One can
take the approach of leaving #+title at the top of the document, and
moving the other config lines elesewhere, but even so I am wondering
whether anyone else is attracted by the idea of providing an org-title
display property that would hide the #+title: component, and use an
appropriate face for the title text.

In some ways, the current state gives the impression that the title is
something which becomes important during export, but is not really a key
component of document when it is being viewed in emacs. For example, I
expect others are familiar with the experience of exporting an org file
without a title, finding that the first heading has been used as a
title, and then going back to add in the title as an afterthought. But a
title is an important part of a document, and I thought perhaps a
special title display would help to make the title more of a first class
citizen in org buffers?

Hi Dan,

I agree.  Maybe he same should be true for DATE and AUTHOR, maybe EMAIL?

Would you like to make a patch for this, introducing a new face
and applying it to these constructs?

[I tried sending this with screenshot images and it got rejected. I've
replaced them with URLs]

I've made a proposed patch (below). This involved making a few decisions
about appearance -- it would be great to get other peoples' views and
alternative proposals.

At the risk of stating the obvious, I think we should ask the question
"What might attract new users to org-mode most?", rather than query our
personal preferences (because we can all change it ourselves or fire off
an email to this list asking how).

Here's my main proposal (corresponding to the patch below). Note that in
the first 4 lines the #+TITLE: and #+AUTHOR: etc bits are still there,
but invisible.

http://www.princeton.edu/~ddavison/org-faces/Default-MidnightBlue.png

The main issue then is that I'm suggesting making the title face larger
than the other faces. This would be the only large face in org-mode, but
I thought that it was appropriate for the title. Here's a version
without the large title face:

http://www.princeton.edu/~ddavison/org-faces/Default-MidnightBlue-NoBigTitle.png

As for the colours, here's an alternative:

http://www.princeton.edu/~ddavison/org-faces/Default-DarkSlateGrey.png

The important thing is the default emacs colour theme shown above, but I
did pick a colour for dark backgrounds. For what it's worth, here is
what it looks like with (the excellent) color-theme-charcoal-black:

http://www.princeton.edu/~ddavison/org-faces/CharcoalBlack-SteelBlue.png

Here's the patch. If anyone wants to play around, it's pretty obvious in
the patch below where to change the colours (and boldness and
height). Don't forget the functions list-colors-display and
list-faces-display.

There's at least one issue with the patch: if you leave a space between
e.g. '#+TITLE:' and the start of the title text, then that space will
not be made invisible and so will appear at the start of the title. I
couldn't see how to avoid that without altering one of the key font-lock
regexps.

Re: suggestion: display of #+TITLE

[Carsten Dominik]

Hi Dan,

I think the patch is almost good.  I do like the larger face
for the title, and I know that some themes also use larger faces
for headlines.

But I think we at least need a variable
governing if the keyword will be made invisible or not.
If you type "#+email:", for example, that string does disappear
without a trace, and that is very confusing.  In fact, my preference
would be to not make the keyword invisible.

Thanks

- Carsten

Re: suggestion: display of #+TITLE

[Scot Becker]

[-- Attachment #1.1: Type: text/plain, Size: 8800 bytes --]

Or what about---in the spirit of the 'hidden' outline stars---the option to
set "#+TITLE:" and friends in a 'barely visible' color, and in the
'standard' font of the document, if that's possible.  As sexy as it is,
really hiding the markup is a fair break from most (all?) of 'standard' org
mode, where what you see is what you got.    Even the invisible starts are
there when you cursor over them.  Just my 2p.

Re: suggestion: display of #+TITLE

OK, I understand that suddenly-disappearing text might be confusing. My
intention was to help in the current efforts to avoid making org seem
too "technical" to people coming from more mainstream software, by
providing a clean document title. But OK, so magical hiding off by
default. Scot's suggestion seems like a good intermediate
position. Below is a new version of the patch which follows that. I
resisted the temptation to go crazy with the "barely visible"-ness, just
the same as other dimmed text in org (archived, code, etc).  An image is
at

Right, apart from links I guess. Org users are used to sudden hiding
behaviour on their part.

In addition to the new faces, I've introduced a new variable
org-hidden-keywords which is a list of special keywords to hide, with a
customise interface. At the moment that allows for hiding
of #+TITLE, #+AUTHOR, #+DATE and #+EMAIL. By default all hiding is off.

Re: suggestion: display of #+TITLE

[Dan Davison]

Thanks Scot, here's the final version of my proposed patch (no change in
outward appearance from previous version).

By default, title, author, date and email lines appear in dark blue with
the initial keywords greyed out. The title is in a larger font than the
others. To change that appearance, customise the faces

org-document-title
org-document-info
org-document-info-keyword

In addition, the variable org-hidden-keywords can be used to make any of
those keywords disappear. You can use the customize interface for this,
or e.g.

(setq org-hidden-keywords '(title date))

Dan

Re: suggestion: display of #+TITLE

[Thomas S. Dye]

Hi Dan,

What a pleasant surprise to see the tastefully displayed #+Title:, #

All the best,
Tom
