Kit to automatically populate a block with content of parent block

Questions & Help
1

Is it possible to populate a block with the content of the parent block using kits? For example

- [[Parent Block Title]]
  - TODO Some task #someone needs to do
    agency-name:: {{parentref}}

Yes:

  • Ensure that kits is functional.
  • Add the following macro inside file config.edn , inside macros{} :
    :pp "<span class='kit' data-kit='parentprop' data-prop='$1'>$1:: parent</span>"
    • Can replace pp with a name of your preference.
  • Inside page ParentProp in Logseq, put the following code in a javascript code-block:
    logseq.kits.setStatic(function parentprop(span){
	if (span.closest('.ls-block:has(a[data-ref=template])')) return

    const blockId = span.closest(".ls-block").getAttribute("blockId")
    const block = logseq.api.get_block(blockId)

    const content = block.content
    const macroName = span.closest(".macro").dataset.macroName
    const macroStart = content.indexOf("{{" + macroName)
    const macroEnd = content.indexOf("}}", macroStart) + 2

    const prop = span.dataset.prop
    const text = logseq.api.get_block(block.parent.id).content
    const replace = (prop === '$1' ? text : '')
    const newContent = content.slice(0, macroStart) + replace + content.slice(macroEnd)
    logseq.api.update_block(blockId, newContent.replace('{{' + macroName + '}}', ''))
    if (!replace) logseq.api.upsert_block_property(blockId, prop, text)
})
  • Now to add the content of parent block to e.g. property propname:: of a block:
    • don’t type this: propname:: {{pp}}
    • type instead this: {{pp propname}}
  • To ignore the property and instead have the content of the parent directly replace the macro, type {{pp}}
    • To replace a macro inside a query, add one more {{pp}} at the end of the block.

You are absolutely awesome! Thanks.

I tried on my own but didn’t have any luck. Can I have a version of the function that only gives me the contents of the parent block? May I also have the corresponding config.edn entry? I tried just making a copying your function and giving it a different name but calling it gave no output.

I’m not sure of what you expect. Please be more specific. Maybe describe the steps that you made, so as to find the misunderstanding.

Thanks for responding. Your current script takes one argument and provides an output like this: $1:: [[parent block]] (example, agency:: [[ENAGB]]). I would like a version that just gives me the parent block content by itself with no argument. For example,

- [[Parent Block Content]]
  -{{pq}}

will give me

- [[Parent Block Content]]
  -[[Parent Block Content]]

My plan is to use this function to dynamically provide the value for block/name in an advanced query based on the value of the parent block. That way, I can query all the tasks and linked tasks for that page. For example

- [[ENAGBE]]
  - #+BEGIN_QUERY
    {:title [:h3 "Tasks with page reference"]
    :query [:find (pull ?b [*])
        :where
           [?p :block/name "{{pq}}"]
           [?b :block/refs ?p]
           [?b :block/marker "TODO"]]}
     #+END_QUERY

I have updated the code to support your scenario with the same macro. Read the additional instructions at the end.
