[patch] ob-clojure: Fix results output

[patch] ob-clojure: Fix results output

[Daniel Kraus]

[-- Attachment #1: Type: text/plain, Size: 418 bytes --]

Hi,

attached is a bigger patch that fixes the result output of ob-clojure.
The commit message contains examples what's currently wrong
and what's fixed.
This is a breaking change though.
So if someone before relied on the fact that, e.g. cider, returns
the result of every expression in every line instead of only the
last one, they get a different result now.

Is it ok to install?
Other feedback?

Cheers,
  Daniel

Subject: [PATCH] ob-clojure.el: Fix results output, support clojure-cli

* lisp/ob-clojure.el (org-babel-clojure-backend): Add support for
clojure-cli.
* lisp/ob-clojure.el (org-babel-clojurescript-backend): Move nbb to
clojurescript.
* lisp/ob-clojure.el (org-babel-expand-body:clojure)
* lisp/ob-clojure.el (ob-clojure-eval-with-cider): Return only the
last expression when :results is not set or value, and return only
stdout when :results is set to output.
* lisp/ob-clojure.el (ob-clojure-eval-with-cmd): Rename function as
it is not only for babashka.
* lisp/ob-clojure.el (org-babel-execute:clojure): Differentiate
between Clojure and ClojureScript source blocks.

The problem was that the ob-clojure results where not correctly
taking the results parameter into account.
E.g. with the cider backend, you would get all printed or returned
values for each line in your block:

(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

| #'user/small-map |
| {:some :map}     |
| 4                |

or for babashka you would only get the printed values but not the
last return value:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: :xx

Now when you specify :results value, the result is only the last
returned value, and with :results output you get all values
printed to stdout.
So the examples above would all result in the same:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: 4

The current behaviour is a bug anyway:

‘value’
     ...
     
     When evaluating the code block in a session (see *note Environment
     of a Code Block::), Org passes the code to an interpreter running
     as an interactive Emacs inferior process.  Org gets the value from
     the source code interpreter’s last statement output.  Org has to
     use language-specific methods to obtain the value.  For example,
     from the variable ‘_’ in Ruby, and the value of ‘.Last.value’ in R.

Does it have to be a single commit? Not a big deal, but two separate
commits would be cleaner.

This is an important new feature that should be announced clearly in ORG-NEWS.

It is no longer a path, despite what is claimed in the docstring.
:type definition is also not accurate.
Also, update :package-version.

This will remove a non-private function. May you leave a fallback
obsolete alias to not break third-party code that calls the old function
name?

I added an entry about the new ClojureScript change.
I guess the other (main) part of the patch is a bugfix and will not
be documented in ORG-NEWS.

I saw that as well but unfortunately I did it all in the same go
and then touch the same code parts, so separating them in individual
working commits, while not a huge task, is still some work with not
much benefit.

ClojureScript source blocks where supported before, but just no way to set
the backend for it separately. See the ORG-NEWS in the new attached patch.

Good reminder. I send a PR for this when this patch is installed?!

This was apparently a kludge that ob-clojure used to evaluate ClojureScript
in the normal clojure:execute function.
I simply used the same kludge where I need to check for cljs, but after
reviewing it's not really necessary and I removed the :target parameter
completely. As this was undocumented I guess it's ok to remove?!

I created an obsolete-function-alias.


Attached is the new patch with the changes.

Subject: [PATCH] ob-clojure.el: Fix results output, support clojure-cli

* lisp/ob-clojure.el (org-babel-clojure-backend): Add support for
clojure-cli.
* lisp/ob-clojure.el (org-babel-clojurescript-backend): Move nbb to
clojurescript.
* lisp/ob-clojure.el (org-babel-expand-body:clojure)
* lisp/ob-clojure.el (ob-clojure-eval-with-cider): Return only the
last expression when :results is not set or value, and return only
stdout when :results is set to output.
* lisp/ob-clojure.el (ob-clojure-eval-with-cmd): Rename function as
it is not only for babashka.
* lisp/ob-clojure.el (org-babel-execute:clojure): Differentiate
between Clojure and ClojureScript source blocks.

The problem was that the ob-clojure results where not correctly
taking the results parameter into account.
E.g. with the cider backend, you would get all printed or returned
values for each line in your block:

(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

| #'user/small-map |
| {:some :map}     |
| 4                |

or for babashka you would only get the printed values but not the
last return value:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: :xx

Now when you specify :results value, the result is only the last
returned value, and with :results output you get all values
printed to stdout.
So the examples above would all result in the same:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: 4

Yes, it is OK to remove what is undocumented. We may still announce the

This is not a path anymore, when the value is "npx nbb".
Can just use "Command to invoke nbb executable".

Moved the alias to org-compat.

It's now in the ~Obsolete aliases~ page.

Subject: [PATCH] ob-clojure.el: Fix results output, support clojure-cli

* lisp/ob-clojure.el (org-babel-clojure-backend): Add support for
clojure-cli.
* lisp/ob-clojure.el (org-babel-clojurescript-backend): Move nbb to
clojurescript.
* lisp/ob-clojure.el (org-babel-expand-body:clojure)
* lisp/ob-clojure.el (ob-clojure-eval-with-cider): Return only the
last expression when :results is not set or value, and return only
stdout when :results is set to output.
* lisp/ob-clojure.el (ob-clojure-eval-with-cmd): Rename function as
it is not only for babashka.
* lisp/ob-clojure.el (org-babel-execute:clojure): Differentiate
between Clojure and ClojureScript source blocks.

The problem was that the ob-clojure results where not correctly
taking the results parameter into account.
E.g. with the cider backend, you would get all printed or returned
values for each line in your block:

(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

| #'user/small-map |
| {:some :map}     |
| 4                |

or for babashka you would only get the printed values but not the
last return value:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: :xx

Now when you specify :results value, the result is only the last
returned value, and with :results output you get all values
printed to stdout.
So the examples above would all result in the same:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: 4

What will happen with users who customized `org-babel-clojure-backend'
to 'nbb in the past?

This docstring is exactly the same with `org-babel-clojure-backend'.
What is the difference?
I think ""Backend used to evaluate ClojureScript code blocks." will be
more clear. I feel that other docstrings may also need to be clarified
depending whether they affect Clojure or ClojureScript blocks.

They would have gotten an error.
I changed it now that 'nbb backend is still allowed in a clojure
source block but it will internally treated as ClojureScript.

I changed the docstrings to always mention either Clojure or ClojureScript.
I'm open for more improvements/suggestions.

Attached a new patch.

Thanks,

Subject: [PATCH] ob-clojure.el: Fix results output, support clojure-cli

* lisp/ob-clojure.el (org-babel-clojure-backend): Add support for
clojure-cli.
* lisp/ob-clojure.el (org-babel-clojurescript-backend): Move nbb to
clojurescript.
* lisp/ob-clojure.el (org-babel-expand-body:clojure)
* lisp/ob-clojure.el (ob-clojure-eval-with-cider): Return only the
last expression when :results is not set or value, and return only
stdout when :results is set to output.
* lisp/ob-clojure.el (ob-clojure-eval-with-cmd): Rename function as
it is not only for babashka.
* lisp/ob-clojure.el (org-babel-execute:clojure): Differentiate
between Clojure and ClojureScript source blocks.

The problem was that the ob-clojure results where not correctly
taking the results parameter into account.
E.g. with the cider backend, you would get all printed or returned
values for each line in your block:

(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

| #'user/small-map |
| {:some :map}     |
| 4                |

or for babashka you would only get the printed values but not the
last return value:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: :xx

Now when you specify :results value, the result is only the last
returned value, and with :results output you get all values
printed to stdout.
So the examples above would all result in the same:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: 4

Ups, sorry.
Before `params` was only used to receive the :target parameter if it's a cljs or clj
block. But that's now just a regular parameter to the function.
I fixed it with a _ prefix.

Cheers,

Now, the docstring appears to be a bit confusing:

(defun ob-clojure-eval-with-cider (expanded _params &optional cljs-p)
  "Evaluate EXPANDED code block with PARAMS using cider.
When CLJS-P is non-nil, use a cljs connection instead of clj."

It would be useful to mention that PARAMS argument is unused.

Should I go with your initial suggestion and just replace it with _?
Like

(defun ob-clojure-eval-with-cider (expanded _ &optional cljs-p)
  "Evaluate EXPANDED code block using cider.
When CLJS-P is non-nil, use a cljs connection instead of clj."

But then someone will maybe wonder why there is unused argument?

Or rather something like:

(defun ob-clojure-eval-with-cider (expanded _params &optional cljs-p)
  "Evaluate EXPANDED code block using cider.
When CLJS-P is non-nil, use a cljs connection instead of clj.
The PARAMS from Babel are not used in this function."


Writing good docstrings is hard :D

Cheers,
  Daniel

I like the second variant better.

Thanks.
I pushed the fix.
