You may want to start Emacs with --debug-on-init flag, and report the

Re: [O] Use CHTML mathjax backend by default

[Carlos Pita]

Also, they said there:

So:

1. Recommended for newer mathjax versions.
2. Fixed my problem with web fonts.
3. Faster.

It seems like a Pareto improvement to me.

[O] Use CHTML mathjax backend by default

[Carlos Pita]

Hi all,

I was having some problems with the mathjax HTML-CSS backend and I
found out that the CHTML backend is currently the preferred one. See
details at https://github.com/mathjax/MathJax/issues/2132 and
http://docs.mathjax.org/en/latest/output.html. Changing the backend to
CHTML fixed my issue.

Wouldn't be time to update the default mathjax version to 2.7.1 (the
current one) and setting the backend to CHTML?

Best regards

Re: [O] "File mode specification error: (user-error Empty table - created default table)"

[John Kitchin]

I saw something like this recently in a little different context. In the
output of a babel block I saw the empty table get inserted around the
results. It only happened in one file, and I didn't notice if there was a
user-error.  I can't reproduce it at the moment, and didn't spend any time
tracking it down. If I see it again I will see if I can track anything
down.

I am using Org mode version 9.2.1 (9.2.1-23-g126a37-elpaplus @
/Users/jkitchin/vc/jkitchin-github/scimax/elpa/org-plus-contrib-20190218/)

And came back out again.  Ignore this whole thread of self-indulgent
posts!  ~org-link-set-parameters~ does the job for me after
all.  Problem was that the regex does get updated but doesn't affect any
open buffers...  My fault.

Thanks and sorry for the noise.

I'm pretty sure the regex is created automatically. I only needed 
to do this:


   (org-link-set-parameters "ebib" :follow #'org-ebib-open :store 
   #'org-ebib-store-link)


And then define the functions `org-ebib-open` and 
`org-ebib-store-link`. (Cf. 
).


And yes, I apologize for the irony. ;-)

I guess this
http://kitchingroup.cheme.cmu.edu/blog/2016/11/04/New-link-features-in-org-9/
will show you most of what you need to make new links.
 org-link-set-parameters Also makes new links.

Re: [O] [PATCH] org-collector.el: Add support for formulas appending

I don't know, hence my question :) However, it is a good habit to
document features, IMO.

OK.

I see there is some documentation in the commentary part. Maybe that
could be a good place. If we move it into core, it would go in the
manual.

Speaking about "org-collector.el", it seems unmaintained. So we should
either move it into core, which may be a good idea, if it is useful
enough, or find a maintainer and move it elswhere (some ELPA, preferably
Org's or GNU's).

Re: [O] ivy-bibtex and orgmode inserts ebib: link

[Eric S Fraga]

I am going down a rabbit hole here...

Short question: how can I add a new link type to org?  It used to be
that we would use ~org-add-link-type~ but this is
deprecated.  Fine.  The documentation points to
~org-link-set-parameters~ instead but this can only set the parameters
for known links.  Known links seem to be defined by a complex regex in
~org-link-types-re~.

What is the replacement for ~org-add-link-type~ in the latest version of
org, if any?  Or do I have to both add to the regex and set link
parameters separately?

Thank you!

Sigh.  As always, I find the answer *after* asking on the list.  I must
learn patience.

Anyway, the answer (in case anybody else wishes to know) is that this is
controlled by the variable ~bibtex-completion-format-citation-functions~
and which defaults to using ~bib-completion-format-citation-ebib~.  I am
not sure this is a reasonable default given that org does not understand
(out of the box) ebib: links.

Hello,

I have started using ivy-bibtex (wonderful package) but I have one
strange behaviour: when I ask it to insert a citation, it inserts
"ebib:".  I have searched but cannot see anywhere where I can tell
ivy-bibtex to insert "cite:" instead.  Does anybody have any
pointers?

Thanks,

Hello,

So these options have to be documented?

I think there'll be more than one update then, for example :noquote and :scope
options were not documented as well. I've been sure that it's okay to check
source code and find all possible features.

Anyway, where should documentation be added? I can prepare additional patch.
