Provide an event/hook for other plugins to hook into, to avoid race conditions

Is your feature request related to a problem? Please describe.

Hi! I am maintaining filename-heading-sync and it's currently not playing nicely with templater, see

• Race Condition with Templater dvcrn/obsidian-filename-heading-sync#55
• I don't know exactly what is this problem, help me dvcrn/obsidian-filename-heading-sync#46

Describe the solution you'd like

I don't want to add an artificial delay before acting on obsidian events, but as a solution, if we could detect that templater is installed, we could wait for a custom event (emitted by Templater) before doing things like renaming files or inserting headings.

Some ideas:

• expose an event target to subscribe to: https://developer.mozilla.org/en-US/docs/Web/API/EventTarget
• provide a way to detect that templater is installed and enabled (like window.templaterEnabled = true)

Also having this issue. Using the new Vaut#process (https://marcus.se.net/obsidian-plugin-docs/reference/typescript/classes/Vault#process) function in both plugins should supposedly fix this. Basically, process allows for atomic modification of the file

if anyone wants to take on converting all of Templater's vault.modify, .append, etc to .process, it would be great. Otherwise I can get a PR out within the next week

Templater is already emitting an event (multiple events, actually, depending on what you want). The creases plugin is the only plugin I know of that is currently hooking into these events.

Moving to app.vault.process() will be tricky, as Templater processes changes asynchronously, and app.vault.process() has to be run synchronously. There will have to be some sort of diff processing if we switch.

No problem. For now, there's a workaround with my plugin, so not urgent on my end. Thanks for the consideration, though

Since Templater is already emitting an event, going to mark this as closed. Thanks everyone for your contributions to this issue!
