• Couple of JS Questions

    From Apam@VERT/POSITRON to All on Monday, May 23, 2022 19:34:00
    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

    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.

    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.

    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.

    I'm working on a mod to turn on a light when I have active nodes - however sometimes the light will stay on after someone logs off, even when no one else is logged in - but there is a active connection by a bot, scanner, or network call of some kind. I'm currently using server.clients to get this number but it's leaving the light on (and not in a good Motel 6 kind of way)

    Is there a better way to get the number of actual nodes with a user actually logged in?

    Iterate through the system.node_list array and count up how many have a status property value of NODE_INUSE (defined in load/nodedefs.js). Or just simply set/return true if *any* of them are in-use (you don't need the actual total).

    That should leave the light on for ya only when there's an actual rent-paying customer. :-)
