You can write it :EXPORT_FOO: and define it in the back-end options. Otherwise, you simply need to retrieve it and store it before calling `org-export-to-file' or whatever.

Do you mean that the "EXPORT_" is a special prefix? Or "EXPORT" is any backend prefix I choose? Should that be added to these? ===== :options-alist '((:hugo-front-matter-format "HUGO_FRONT_MATTER_FORMAT" nil org-hugo-front-matter-format) (:hugo-tags "HUGO_TAGS" nil nil) ===== I already tried above, but I don't know how to get the ":HUGO_TAGS" value from the property drawer, in subtreep export only, in the body filter (with only body and info available). If it is a full document export, I can use the "org export parse headlines" function (forgot the name, on the phone at the moment) to get the properties from each headline. But the same doesn't work when exporting just one sub-tree. Otherwise, you simply need to retrieve it and store it before calling > `org-export-to-file' or whatever. Hmm, will give this a try.. may be look at the pre export hook?

You can also do that, if you don't use the "EXPORT_" prefix above. However, you need to expand the buffer first, because it will be narrowed to the current subtree.

For reference: > When exporting sub-trees, special node properties in them can override the above keywords. They are special because they have an ‘EXPORT_’ prefix. For example, ‘DATE’ and ‘OPTIONS’ keywords become, respectively, ‘EXPORT_DATE’ and ‘EXPORT_OPTIONS’. Except for ‘SETUPFILE’, all other keywords listed above have an ‘EXPORT_’ equivalent. > > Should that be added to these? > > > > ===== > > :options-alist '((:hugo-front-matter-format "HUGO_FRONT_MATTER_FORMAT" > nil > > org-hugo-front-matter-format) > > (:hugo-tags "HUGO_TAGS" nil nil) > > ===== > > If you set this, you can access to EXPORT_HUgo_TAGS property > with :hugo-tags. > Thanks. That works. Just curious though.. if one specifies certain keywords to be exporter specific keywords in the backend definition in :options-alist, it is evident that those keywords are specifically for export. Should the requirement to have "EXPORT_" prefix before them be relaxed? Do you foresee things not happening right if we started doing that? > > I already tried above, but I don't know how to get the ":HUGO_TAGS" value > > from the property drawer, in subtreep export only, in the body filter > (with > > only body and info available). > > (plist-get info :hugo-tags) > I was already doing that, but I was missing the "EXPORT_" prefix in the property drawer keys.

So I have two options: - Make use of the inbuilt EXPORT_ prefix and get rid of the "HUGO_" prefix from the exporter backend definition. Then if categories are specified per-Org-file, it would look like "#+CATEGORIES: foo bar", and if they are specified per subtree, it would look like ":EXPORT_CATEGORIES: foo bar" in the property drawer. - Do not use the "EXPORT_" keyword in the property drawers, but then either do the pre-export parsing, or.. above suggestion to update Org ox to not require "EXPORT_" before FOO if FOO is a special keyword defined in the backend? > However, you need to expand the buffer first, because it will be > narrowed to the current subtree. I need exactly that. My idea is to have a single Org file with one subtree per a blog post. So each subtree will have meta data about that post, like data, categories, etc. -- Kaushal Modi [-- Attachment #2: Type: text/html, Size: 4296 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread

User may not be aware of keywords defined in export back-ends. As a consequence user-defined properties could interfere with export specific ones. E.g., ":TITLE:" and ":EXPORT_TITLE:" could mean different things. > - Make use of the inbuilt EXPORT_ prefix and get rid of the "HUGO_" prefix > I need exactly that.

So each subtree will have meta data about that post, like > data, categories, etc. I meant that you probably need to expand the buffer in order to get the properties. Once this is done, you can return to the original narrowing. Regards, -- Nicolas Goaziou 0x80A93738 ^ permalink raw reply [flat|nested] 6+ messages in thread
