Document containing different text colours?

Document containing different text colours?

[Sharon Kimble]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512


In a book that I am writing, the text is white on black background which
I like. But this is only the first draft, when its ready I shall go onto
the second draft and then third draft, as many as necessary to polish
the book before it goes to the beta-readers.

So the first draft is white text on a black background, is it possible
for all the second draft text to be in a different colour that I assign
to it? And ditto third draft onwards?

I envisage something like setting the text with 'M-x second-draft-text'
which will then display the new text with its assigned colour. Which
will also mean that the document will have multi-coloured text in it?

Is this possible?      

And if it is possible, how do I do it please?

Thanks
  Sharon.

Hi Sharon,

I'm not sure I understand what is it that you are trying to do. But color
(or any other visual) is a feature of the exporter you use rather than of
Org-mode itself. For example, if you are exporting to HTML, you can use the
following at the top of the document:

#+html_head_extra: <style>body { color: white; background-color: black;
}</style>

For LaTeX export, you should be able to add the correct settings using #+
LATEX_HEADER_EXTRA.

Hope this helps,
--Diego

Thanks for replying Diego.

The text of the book will not be exported into latex or any other
forward-type document. I need the coloured text purely for my own
interest and usage. When, and if, I do export it to latex, LibreOffice
doc or whatever, it will just have the standard coloured text of black
text on a white background. But I need different coloured texts in
org-mode to show me graphically where I added in new text to the book,
and at what stage of the drafting.

For instance - first draft is white text, second draft is lime-green,
third draft is light-blue, fourth draft is pale-red, etc.

So in the above instance I would have white text, lime-green text,
light-blue text, pale-red text, etc ... all in the same document.

Is that clearer?

Thanks
  Sharon.

Hi Sharon,

I understand - you want something like a "change tracking mode". I do not
really know if you can manually set custom faces on the text of a buffer
(you probably can, but I don't know how).

If you use git for version control, I found diff-hl mode (
https://github.com/dgutov/diff-hl), which highlights the changes since the
last committed version. Maybe this helps? For example:

Best,

Re: Document containing different text colours?

[John Kitchin]

This would not be too easy to achieve.

One way I can see it happening is if you keep your manuscript in a VC
system like git, and you tag the different draft versions. Then you use
the VC diff machinery to find the diffs between the versions, and
somehow use that to put color overlays or text properties.

latexdiff can do something like this but only for two versions, not
multiple versions. Even the fanciest of diff programs I think can only
deal with three files (versions).

You might find some insight at
https://github.com/jkitchin/scimax/blob/master/scimax-editmarks.org#from-git-diff.

this uses the scimax-editmarks package I have been working on, and uses wdiff
to markup the differences between two versions of a file in a git repo.

Looking back on this you should expect a rainbow soup of issues, for
example, how would you deal with text that has been deleted? or moved
around, or changed a few times between versions.

I am not sure it would be easy to figure out how to do this for multiple
versions.

Re: Document containing different text colours?

It feels to me like this should be possible because syntax highlighting 
mixes colors.  I am woefully inadequate to help, but I feel like 
mentioning this might spark a guru's imagination.

I remember years ago when I used Notepad++ on Windows it allowed 
user-defined syntax highlighting, and I did so for my GTD system at that 
time.  I have no doubt one could create a personal syntax highlighting 
scheme in Emacs, but (how(me(ask(don't)))! <--- I'm sure that's absurd, 
but hopefully a funny indicator of my ignorance.

It would be a stop-gap with some pitfalls, but perhaps make all 2nd 
draft text bold and all 3rd draft italics.  The obvious pitfall is any 
already emphasized first draft text.

hi-lock-mode may do what the OP wanted with some careful insertion of
tags in the document, maybe in the form of comment lines.
