Hi

I'm mucking around in JS, and am creating a gemini service for synchronet. It serves files in /sbbs/text/gemini/ (not exactly hard coded, i'm using system.text_dir + "gemini".)

First question, is it possible in synchronet javascript to determine the mime-type of a file?

At present I'm just using a switch statement based on the extension - is this the best way to do things?

The second question, I'd like to add cgi type interface, which would load javascript files from the gemini root. I'm unsure how to execute another javascript file from within a service javascript file (or at all).

Hi

I'm mucking around in JS, and am creating a gemini service for synchronet. It serves files in /sbbs/text/gemini/ (not exactly hard coded, i'm using system.text_dir + "gemini".)

First question, is it possible in synchronet javascript to determine the mime-type of a file?

You could load ctrl/mime_types.ini using the File class and compare the extension.

At present I'm just using a switch statement based on the extension - is this the best way to do things?

Ideally, you'd use the same mime_types.ini file used by the web server.

The second question, I'd like to add cgi type interface, which would load javascript files from the gemini root. I'm unsure how to execute another javascript file from within a service javascript file (or at all).

load(), require() and js.exec() are used to execute a JS file from a JS file. --

Great. That's what I'm now doing.

load(), require() and js.exec() are used to execute a JS file from a JS file.

Thanks! I've not done this yet, but will soon.

If anyone is interested in looking at it, I put it up here:

I think I need to use js.exec.apply() so I can pass the query argument.. but can't seem to find any information on it..

I see it's used in install-xtrn

var result = js.exec.apply(null
,[js_file, item.startup_dir, {}].concat(js_args));

but unsure what that first null is.

js.exec() is a function, so: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/apply

Thanks! I feel like such a newbie lol I had assumed it was a synchronet command and was going through the synchronet javascript stuff on the wiki.
