Literate config and :tangle clauses

Literate config and :tangle clauses

Hi all!

Recently I've experienced a kind of a problem - my literate Emacs config
stopped tangling correctly, only a subset of code blocks were found in
resulting .el file. 
I've looked at it a bit closer and it seems now (not earlier than 9.0.2)
the :tangle clause became required. I've searched Org repo but failed to
find a respective commit or any reference to the relevant info.

Can anyone point me to the right direction? 

regards,
Alex

I also experienced the same behaviour. :tangle became required, which it
wasn't previously.

My solution was just to add the ":tangle yes" tag everywhere.

I don't think the problem lies with any revision to org.

First, what `C-h v org-babel-default-header-args RET' shows below is
unchanged for at least a year:

--8<---------------cut here---------------start------------->8---

org-babel-default-header-args is a variable defined in ‘ob-core.el’.
Its value is ((:session . "none")
  (:results . "replace")
  (:exports . "code")
  (:cache . "no")
  (:noweb . "no")
  (:hlines . "no")
  (:tangle . "no"))

...
--8<---------------cut here---------------end--------------->8---

Note that `(:tangle . "no")' sets the default behavior.

Second, I have files that depend on the above. i.e. I set the header
on a few blocks to `:tangle yes' and leave the rest alone, relying on
the above default to keep them from being tangled.

Use

#+PROPERTY: header-args :tangle yes

(and type `C-c C-c' to reset the buffer the first time you type it)

and review

(info "(org) Using header arguments")

for tips on how to control the application of header args.

Yes, I've ended up doing the same. It's not a problem at all, but I was
just curious how has it gone that way.

Hi, Chuck

I do not blame Org at first place, but I've bisected my config and the
behaviour is the same for a significant list of commits deeper in git
history. And, as I've already mentioned, it started to behave as
described only some time ago (about a week), after one of the package
updates. Presumably the root cause can be found elsewhere...

regards,
Alex
