Rename embedded assets

This is:

an imperfect workaround for Better (human-readable) asset name
inspired from File management from within Logseq, proof-of-concept, but fully independent from it
- In contrast to the above, this one is secure, as it exposes only assets folders.

Usage

At the end of file preload.js, normally inside ...\Logseq\app-0.9.13\resources\app\js, add these lines:

contextBridge.exposeInMainWorld('renameasset', (path, oldName, newName, cb)=>{
  const assetsPath = path + "/assets/"
  fs.rename(assetsPath + oldName, assetsPath + newName, cb)
})

This gets affected by updates.

Add a macro inside file config.edn, inside macros{}:

:rename-asset "<div class='kit' data-kit='renameasset' data-new-name='$1' />"

This code requires having kits inside file custom.js
Inside page RenameAsset in Logseq, put the following code in a javascript code-block:

const LS = logseq.api
const Msg = logseq.Module.Msg
const rename = window.renameasset
if (!rename) return Msg.error("missing renameasset")

logseq.kits.setStatic(function renameasset(div){
    const blockId = div.closest(".ls-block").getAttribute("blockid")
    const block = LS.get_block(blockId)
    const parent = LS.get_block(block.parent.id)
    const content = parent.content
    const index = content.lastIndexOf("/")
    const oldName = content.slice(index + 1, content.indexOf(")"))
    const newName = (div.dataset.newName !== "$1") ? div.dataset.newName
        : oldName.slice(0, oldName.indexOf("_")) + oldName.slice(oldName.lastIndexOf("."))
    const newContent = content.slice(0, index + 1) + newName + ")"
    const path = LS.get_current_graph().path
    rename(path, oldName, newName, (err)=>{
        if (err) return Msg.error(err.message)

        LS.update_block(parent.uuid, newContent)
        LS.remove_block(block.uuid)
        Msg.success("done")
    })
})

Under any (*) embedded asset (looks like ![text](link) ) add a temporary child-block:
- Put the following content:
  - If it is auto-named, to fix its name:
```
{{rename-asset}}
```
  - To use a different name:
```
{{rename-asset somename.ext}}
```
- This should:
  - rename the file
    - doesn’t check for same-named file
  - rename the link
  - delete the temporary block
- (*) The parsing is simplistic, so any extra content in the asset’s block may interfere.
