Merging org files for Hugo static site generation
I have just started the process of reducing the number of org files I maintain for my web site. I now have a greater understanding of how Hugo handles these files and I think can both simplify and make them more flexible.
Hugo is my static site generator of choice and although it supports
org files directly I prefer to generate to a markdown file as an
intermediate step using a file by file evaluation of
org-hugo-auto-export-mode. This means that each org subtree I
modify automatically generates an md file to a defined folder
#+hugo_section in the org header.
For example, I have a few org files that generate my art blog; one for
videos, finished art, galleries and now AI. Each org file has a
#+hugo_section defining the destination export folder.
I think now I would like a bit more flexibility with the ability to
push a subtree to a folder of my choosing so any extra sections can
more easily be added. Plus, if I merge I would only have to maintain
a single org file (although a larger one!).
To achieve this I will have to add an extra property to the existing
org drawer for each subtree using
:EXPORT_HUGO_SECTION: and then to
Now of course to add the subtree property emacs can certainly help me out.
I would like to insert typically a drawer property line for each subtree such as:
However of course things are not quite so simple. It seems that some
subtrees already have such property lines even though the destination
folder is ultimately the same as
#+hugo_section in the header
(another good reason to tidy up)
So rather than a simple
isearch to an ever present subtree anchor
point (for example
:EXPORT_FILE_NAME:) and then the insertion of the
new line I will need to take into account those subtrees that already
:EXPORT_HUGO_SECTION: and not insert a line.
I considered edit mode in
multi-occur but as far as I can tell it
doesn’t work too well when new lines are inserted.
deadgrep (ripgrep) also has similar functionality and will also show
context around the search point which can be also edited in a similar
multi-occur but all this is starting to feel too fiddly
and I am starting to spend too much time investigating this!
The grep/occur to edit buffer approach can work well in certain situations but this is a little more complex involving a small amount of logic. At this stage the same thought always occurs to me and I really wish it would occur to me earlier.
what about macros?
isearch technique won’t quite work (as explained above), but
As the properties are always in the same order I could just insert the
:EXPORT_HUGO_SECTION: line if I find the following regex:
Note that the carriage return is achieved by
Incorporate this into a macro and the cursor will only move to a point
that doesn’t have a
:EXPORT_HUGO_SECTION: line and hence I can then
insert and then repeat until my org file is suitable amended!
