Re: [PATCH] Allow tangling to a list of files

[Jacopo De Simoi via "General discussions about Org-mode." <emacs-orgmode@gnu.org>]

Dear Vladimir, 

 thanks for your reply.

Let me show you two examples; they are both WIP and incomplete, but you'll get 
the gist. 

- Example 1

https://gist.github.com/85c9b9c9ab151c5fd35bd761ef6ef569

This is my literate config for .zshrc; as you can see different blocks are 
tangled to different set of files; hence the output files differ (as some blocks 
are present and other are not) 

- Example 2

https://gist.github.com/2bce5d6df3f04c934fb4beda0c6560ad

This is my literate config for xkb maps; I have several keyboards, and some of 
them require slightly different maps.

Once again, likely all this can be accomplished by some noweb magic, but I find 
my approach much less intrusive (particularly the initial bit in the .zshrc, 
which I am still refactoring, where the list of tangle targets is inferred 
from the headline tags)

Thanks again for your comments. I'd really like to see how to do the same with 
noweb and compare my approach with the "standard" one. Once more, I hope these 
examples clarify my point of view. 

Best 
 Jacopo
