idempotency and inconsistency for org-babel-remove-inline-result

idempotency and inconsistency for org-babel-remove-inline-result

[Daniele Pizzolli]

Hello,

I really like the new inline results.  Thanks for this new cool feature.
I have only a few problems with it.

Is there a way to evaluate a buffer an then remove inline results or
better, to get the very same buffer after:

(org-babel-execute-buffer)
(org-babel-map-inline-src-blocks nil (org-babel-remove-inline-result))

Every call add an extra white space:

Original:

1 + 4 in R is src_R[:exports results]{1+4}.

After (org-babel-execute-buffer):

1 + 4 in R is src_R[:exports results]{1+4} {{{results(5)}}}.

After: (org-babel-map-inline-src-blocks nil (org-babel-remove-inline-result))

1 + 4 in R is src_R[:exports results]{1+4} .

After (org-babel-execute-buffer):

1 + 4 in R is src_R[:exports results]{1+4} {{{results(5)}}} .

And so on...

I see that the function docs says: Extraneous leading whitespace is
trimmed. Is this the intended result?


Also, is there anything that prevents to make
org-babel-remove-inline-result interactive as is
org-babel-remove-result?  Wwhy not have also
org-babel-remove-inline-result-one-or-many and
org-babel-remove-all-result-one-or-many to remove all the babel result
with one function call?

I do no not know lisp a lot, but I can try to submit a patch if you
agree that will be useful.

Thanks in advance,
Daniele

It is intended to remove `extraneous' whitespace. But the way
`extraneous' is operationalized leaves something to be desired if
users wish to do as you have done. Maybe preserving whitespace (if any)
after the result and deleting all that is before it might work.

I'll take a look at changing the defn to deal with your ECM.

AFAICS, no.

Easy enough, but is this really needed? What about call block/line 
results?

The main issue (IMO) is figuring out what whitespace to delete around
a `{{{results(...)}}}' macro. I can get to this in a day or so, but
feel free to send a patch.

This is useful for me because I want to easily discard the results to
have the commit with only the changes in the source.  I hope others find
this a reasonable facility.  It is like a 'make clean' for your org
files.

Patch attached.  I am not sure about the default of discarding keyword
Deleting the result line can cause some disorder, but it is the default
in org-babel-remove-result.  Also the naming can be confusing.

This is above my lisp coding abilities, with too many org-related
function to get lost into org-babel-remove-inline-result...  I can wait,
but if you have any pointer I will be happy to do some exploration.

Thanks again,
Daniele

RFC: the patch to `org-babel-remove-inline-result-one-or-many' 
removes inline results, too.

Do you see any bad consequences?

There is now a bugfix on master. I've also added 'interactive' to 
`org-babel-remove-inline-result'.

Yes.

See attached patch which should clean *all* results (except `raw' results) 
from a buffer when `org-babel-remove-result-one-or-many' is called with a 
prefix.

Before pushing this, I'd like some feedback on the wisdom of doing what 
the patch does.

I think extending `org-babel-remove-all-result-one-or-many' to cover 
inline results is innocuous. So if nobody raises an objection, I will 
push the patch.

I got that you want to clean up your buffer. But an issue with adding 
more functions is 'feature bloat'. If you really need 
`org-babel-remove-result-all' and 
`org-babel-remove-inline-result-one-or-many' you can have private 
functions.

Thank you.

Regarding patches, if you haven't signed FSF copyright papers a TINYCHANGE 
is needed in the commit message.

Alas. Then there is the user error I have made of re-using names.

Let me try to explain better my use case, that is not covered by this
patch, but was covered by mine.

Currently org-babel-remove-result has an optional argument to keep the
named block results at their position.  I will call this feature
clean-result.  I think that this is more useful that the default
remove-result.  The rationale is that removing the results will lead to
some inconsistencies if you remove and re-execute the buffer, for
details see:
http://lists.gnu.org/archive/html/emacs-orgmode/2013-09/msg00872.html

So I will be happy if a native function take care of this use case.
Maybe a new function with clean in the name instead of remove will solve
this?  Or it will add additional confusion as the inline sources are
removed but the blocks cleaned...

Also, I do not really see the point of having
org-babel-remove-result-one-or-many, since the one case is already
covered by org-babel-remove-result, but maybe there is some additional
magic that I do not understand.

But why a `native' function? You know how to achieve this result and
can

1. add a customized function to your init file,
2. submit a snippet to Worg, and/or
3. contribute an *add on*, and/or
4. argue for changes/additions to the Org code base, what you call a
    `native' function.

Option 4 generates work for those who maintain Org code, so it needs
to be justified in terms of usefulness to other users and
issues in the code that it might fix or complicate.

Even if 4 is the right path, a decision is needed on whether to add
new functions, or change the behavior of existing functions (possibly
adding a new variable or customization). The latter might be cleaner,
but runs the risk of breaking someone's code.

Let's see what others add to this discussion.

The latter notion is along these lines:

#+BEGIN_SRC emacs-lisp
   (defun org-babel-remove-result-one-or-many (x &optional keep-keyword)
     "Remove the result of the current source block.
   If called with a prefix argument, remove all result blocks and
   results macros in the buffer. When KEEP-KEYWORD is non-nil, allow
   RESULTS keywords to remain."
     (interactive (list current-prefix-arg
                        (y-or-n-p "Keep RESULTS keyword(y/n):")))
     (if x
         (org-babel-map-executables nil
           (org-babel-remove-result nil keep-keyword)
           (org-babel-remove-inline-result))
       (org-babel-remove-result nil keep-keyword)
       (org-babel-remove-inline-result)))
#+END_SRC

which seems to handle Sebastien's `bug' if the user responds with 'y' (or 
a calling function has a non-nil `keep-keyword'.

It passes

 	make test

However, there remains the need to add something to 
testing/lisp/test-ob.el.

WDYT?

Thanks for your reasoning and conclusion.

(y/n) seems to be redundant: y-or-n-p prints the options by itself.

Seems reasonable to me.  But I still think that one-or-many does not
have a lot of sense since there is the one-case function already.

Is it possible to call it by something like C-u C-u M-x
org-babel-remove-result-one-or-many or by a custom keystroke and avoid
the interactive prompt and have it to clean all the result keeping the
keyword (without writing a function or using lambda)?

As a novice I like interactive prompt because you can be lead through
the choices, but I do not want to be annoyed by them when I become
expert and have the answer ready and it is almost always the same one.

If not, no worries, I think I will wrap in a custom one.

Thanks again,
Daniele
