suppress leading ":" in org-babel output

suppress leading ":" in org-babel output

[Jeremie Juste]

Hello,

I recall seeing this thread on the mailing list but I cannot find it
back.

I would like to suppress the first line leading ":" in the following output


#+NAME:mean_purchase_per_shopping_trip
#+BEGIN_SRC R :var x=6 :results output :session *R*
a <-sprintf("%.2f",12.234324)
cat(a,sep="\n")
#+END_SRC

#+RESULTS: mean_purchase_per_shopping_trip
: 
: 12.23


Best regards,
Jeremie

FWIW, I just get the last line:

#+NAME:mean_purchase_per_shopping_trip

#+BEGIN_SRC R :var x=6 :results output :session *R*
a <-sprintf("%.2f",12.234324)
cat(a,sep="\n")
#+END_SRC

#+RESULTS:
: 12.23

I get what Jeremie reports (but he has a blank line inserted after the first line, IIUC)

This is with:

GNU Emacs 26.1 
Org 9.2.3
ess-version: 18.10.3
R version 3.6.0 (2019-04-26)

I believe this is new-ish behavior. I see some older files without the extra line. Also, I think there are recent changes in ESS that pertain to comint sessions.

FWIW, here is a clip from my session:

--8<---------------cut here---------------start------------->8---
> x <- 6L
a <-sprintf("%.2f",12.234324)
cat(a,sep="\n")
'org_babel_R_eoe'
> > 
12.23
> 
[1] "org_babel_R_eoe"
--8<---------------cut here---------------end--------------->8---


If Nick sees something different maybe a change in ESS is the culprit.

Not sure what the right path forward is ob-R.el, but as a workaround the OP can use a :post header arg to strip the offending line.

HTH,

Chuck

Here's what I see in the session buffer:

Hello,

Many thanks updating org-mode resolved the issue

Re: suppress leading ":" in org-babel outputariBLE

[Berry, Charles]

AFAICS, the latest update (99aa984) did NOT fix the issue.

There are complications in this story that I explain here.

If I start a fresh *R* session by eval'ing the src block, I get

#+RESULTS:
: 
: 12.23

and the *R* buffer ends with

--8<---------------cut here---------------start------------->8---
> x <- 6L
a <-sprintf("%.2f",12.234324)
cat(a,sep="\n")
'org_babel_R_eoe'
> > 
12.23
> 
[1] "org_babel_R_eoe"
> 
--8<---------------cut here---------------end--------------->8---


If I then open a buffer in ESS[R] mode and run ess-eval-line-visibly-and-step (e.g. by typing C-c C-n)

and then eval the src block again, I get 

#+RESULTS:
: 12.23

and the *R* buffer ends with

--8<---------------cut here---------------start------------->8---
> x <- 6L
a <-sprintf("%.2f",12.234324)
cat(a,sep="\n")
'org_babel_R_eoe'
> > 12.23
> [1] "org_babel_R_eoe"
> 
--8<---------------cut here---------------end--------------->8---


Presumably, a comint or ess variable has changed to effect these differences.

I am unable to discern what variable that is. 

I suspect that the changed behavior Jeremie sees now was do to something similar and that a fresh start will result in the extraneous line in the results.

:-(
