[O] refiling as child with function-filing-location
Hi, I'm writing a custom function for use with a capture template, as described in the section Template elements (sec 9.1.3.1) of the info manual. My function does what I expect in that it finds the correct heading (in my use case Log) and returns point. However, if the Log heading has no children, the capture template is filed as a sibling, and not a child. I have spent some time now on this seemingly simple problem, but being a newbie on elisp I must admit I'm stuck. Here's an example outline: * Projects ** Prj 1 *** Log *** Tasks Clocked entry So, the capture template should end up as a child to Log. From what I could tell by reading the documentation, the capture template is placed at a given level by the org-paste-subtree function, which in term is derived from the *visible* headings. If the Log entry already has a child, capture indeed places the template at the desired level, but how do I acquire this behaviour if there are no children? My function currently looks up the clocked entry, ascends to level 2 and looks for Log among the children: (defun peru/org-capture-project-log nil (org-clock-goto) (while ( (funcall outline-level) 2) (org-up-heading-safe)) (org-goto-first-child) (while (not (string= (nth 4 (org-heading-components)) Log)) (org-goto-sibling) ) (if (not (string= (nth 4 (org-heading-components)) Log)) (error No Log entry under current project; please add)) ;; From org-paste-subtree: ;; if cursor is at beginning of headline, same level used (goto-char (point-at-bol)) ;; Alternatively put at eol; level derived from visible headings ;; (goto-char (point-at-eol)) ) I have thought of an alternative tag-based way of grouping my log entries, but I would still like to understand what I'm missing here.

Patch welcome.
Cf. a recent thread on emacs.devel it's pretty non-trivial to make
preview-latex work outside of AUCTeX.
sub/superscript works well with entities and makes it very easy to
edit math and get approximate live feedback.
Unfortunately, some users complain about the approximation. OTOH, I'm
pretty sure that most LaTeX users can parse sub/superscript LaTeX code
without any fontification at all.
Of course they can, but it takes more effort. Compare:
(1) \beta E_{t}[\sum_{j=t}^{T} z_{j}^{e}]
(2) βE_{t}[∑_{j=t}^{T} z_{j}^{e}]
(3) βEₜ[∑ⱼ₌ₜᵀzⱼᵉ]
(3) takes no effort to read, whereas the barebone (1) and the
entities-only (2) still take considerable amount of effort to parse
IMO.
IOW and IMO, the bug, if any, is the fontification of superscript in
math.
This is not Org's job since you're talking about a non-compatible
syntax. I think it should be done in a different library (i.e., not
org.el), if at all.
An external library is ideal (had it existed), but where to stop? Are
entities wrapped in math supported syntax?
E.g. $\alpha\beta\gamma\delta$.
You want to implement a subset of Auctex. Either you delegate it to that
major mode (à la Babel), at the price of some slowdown, or you duplicate
code from it (i.e., `font-latex-match-script').
In both cases, you need to know when point is on a math snippet or
environment, which should rely on `org-element-context' if you're
serious about it.
So your strategy would be to disable fontification within math (since
the syntax is not org), and delegate it to a separate library, say
tex-fold.el (which also doesn't work out-of-the-box in Org-buffers)?
In theory it's ideal, but consistency (e.g. supported entities) and
comparability is probably issues.
I know nothing on the technical level of fortification so I'm not sure
I could work on this issue efficiently.
This doesn't solve the leak of Org's fontification on math snippets and
environments.
But it would if you can delegate parsing of math to a separate
library, no?

Unfortunately, some users complain about the approximation. OTOH, I'm
pretty sure that most LaTeX users can parse sub/superscript LaTeX code
without any fontification at all.
If there is no easy way to fix it, I may prefer to disable this
fontification,
because it displays something which is wrong (also the superscript is too
small in my opinion,
sometimes the character is unreadable).
The current \(a^nb^n\) is actually displayed as \(a^{nbn}\) which is
misleading.
This is what bothered me first.
OTOH, I have set up preview of formulas (actually I did it for tikz
diagrams) and it works well.
It is slower, and I use it for complicated formulas only, but at least it
is exact.
