Edit and run javascript code inside Logseq itself

[Sininho_Sininho]

It works great! (once I started to get the hang of it ) Thank you for the awesome work!

@mentaloid

mypage should be the actual name of the module’s page

The only thing I find a bit inconvenient is that every macro needs it’s own page. If I understand it right, they cannot even have their own namespace (like kits/macro1), because the entry function needs to have the same name as the page name, right? That means a lot of extra pages on my graph if I want many small macros.
Or maybe I am missing something, or understanding something wrong?

Thank you again for the great work!

Also thanks to @adxsoft for the demo graph (super helpful!) and to @dannylin108 for the question below which saved me quite a bit of headache )

@dannylin108

if I change code of mypage function on mypage page, how to make loqseq to update it?

@Sininho_Sininho

the entry function needs to have the same name as the page name, right?

• This is the convention for routing a macro to some code that has not been loaded yet.
• For more flexibility, either:
  • use a routing macro that redirects execution based on either:
    • its first parameter
      • Thus instead of e.g. {{m1 arg1 arg2}} to use e.g. {{k m1 arg1 arg2}}
    • some html attribute in the macro’s definition
      • read in the entry function with .dataset or .getAttribute
  • implement your own routing by modifying e.g. function runPageByName
    • For example, you could possibly force all code-pages under namespace kits, e.g. with logseq.api.get_page("kits/" + pageName)
      • This is just some untested idea.
  • move to Synthesis
    • It can run code just like kits, but at the level of blocks.

@mentaloid

force all code-pages under namespace kits, e.g. with logseq.api.get_page("kits/" + pageName)

I will try it out. Thanks again!

I’ve noticed that from time to time, the buttons I have defined using your suggested code stop working. This seems to happen more often on my iPhone than on my Mac, but it does happen on both.

It only happens in an already-running Logseq instance, usually after it’s been running for awhile, and after I’ve been doing other things on the device. Restarting Logseq always fixes the problem. Any idea what may be causing this, or how to diagnose and/or fix it?

[mentaloid]

I need something reproducible.

• What about re-running the macro?
  • editing the block
  • reopening the page
• Do you use multiple identical buttons?
• Do you have multiple buttons in the same block?
• Do you have buttons on the sidebar?
• Generally, anything suspicious that could lead to something reproducible.

Thanks. I was about to update my question, because I realized that I’m having two separate issues.

On the Mac, it’s this one, specifically related to an updated version of my query and your MassDelete script. My other button continues to always work on the Mac.

So the issue with buttons in general stopping working is so far limited to the iPhone.

@mentaloid

What about re-running the macro?

• editing the block
• reopening the page

I’ll check this next time it happens on the iPhone

@mentaloid

Do you use multiple identical buttons?

Not in the same page.

@mentaloid

Do you have multiple buttons in the same block?

No

@mentaloid

Do you have buttons on the sidebar?

No (now that we’re just talking about the iPhone)

@mentaloid

Generally, anything suspicious that could lead to something reproducible.

I’ll keep my eye out for anything reportable. There’s no way I know of to access the console on the iPhone, so options are limited.

Is there a way to embed one of these macro buttons within HTML and have it run the JS on another page when clicked or create a slash command that can run the JS on another page?

When I paste this button tag within LogSeq, it runs when the button is rendered but not when I click on it. Is there a way to have it run only when clicked?
<button class='kit run' data-kit='JS/Hello World'>Click Me</button>

Edit: The below button setup only runs when clicked.
<button class='kit run' data-kit='runpage' data-page-name='JS/Hello World'>Hello World</button>

I’m still curious if there’s a way to run a page using a slash command instead of needing to click a button

[mentaloid]

To run page JS/Hello World:

• with a button, the provided way is {{runpage JS/Hello World}}
• on demand without a button, consider using the console for something that calls logseq.Module.Kits.runPageByName("JS/Hello World")

[jpi_joshg_09073]

Using {{runpage JS/Hello World}} is a decent solution for what I’ve been doing. Many times, it requires accessing the “current block”, so using the console isn’t ideal - console also isn’t supported on mobile.

I was curious if there was a way to register a slash command through logseq’s native API (which is different from the plugin API) to run a JS page. Having a slash command reduces the steps from adding the button and clicking on it to running the slash command.

[mentaloid]

Consider implementing a keyboard listener (e.g. like this one) that makes the above call, potentially reading any arguments (e.g. page name) from the textarea.

[jpi_joshg_09073]

That’s a neat idea on how to add a customizable keyboard shortcut; I’ll have to look into it.

Thanks for sharing!
