  • setTimeout and data storage

    From Xeanalyth@VERT/OGLAROON to DOVE-Net.Synchronet_JavaScript on Fri Jul 20 02:25:04 2012
    Hi All,

    Just a couple of questions about the JS implementation in SBBS..

    Firstly, a question about timed events:


    Reading script from /home/bbs/mods/stock/main.js
    /home/bbs/mods/stock/main.js compiled in 0.00 seconds
    Hello World
    !JavaScript /home/bbs/mods/stock/main.js line 13: ReferenceError:
    setTimeout is not defined
    /home/bbs/mods/stock/main.js executed in 0.02 seconds


    setTimeout is not defined? How does one go about executing
    timed events?


    Secondly, is there a standard way for SBBS apps (doors, utils and
    other things) to store arbitrary data in a database style format?
    I cannot find anything in the API documentation that looks like
    it's supported.

    If there isn't... what are other people using for their persistent
    data stores for extensions to and doors for SBBS?

    In Synchronet, the term "timed events" means programs/modules/scripts that the sysops has configured in SCFG->External Programs->Timed Events. I assum you mean something else. Perhaps you want a background thread which executes a JS function at a predefined interval? One way to do that would be to use a background load() of another JS file which contain's that function which sleeps() between intervals.

    Secondly, is there a standard way for SBBS apps (doors, utils and
    other things) to store arbitrary data in a database style format?
    I cannot find anything in the API documentation that looks like
    it's supported.

    If there isn't... what are other people using for their persistent
    data stores for extensions to and doors for SBBS?

    ini files (using the Synchronet File class) is one method (see binarydecoder.js
    for an example), json files is another method (see exec/load/json-db.js and friends for a helpful library). One sysop had a patch which added support for sqlite to Synchronet, but I'm not aware of any apps (doors, utils, etc.) which use it (yet).

    timed events?

    Careful with that "timed events" term - it has its own meaning in Synchronet (stuff that's been scheduled via SCFG.)

    While we don't have the setTimeout function that's present in many browsers, we do have exec/load/event-timer.js, which mcmlxxix wrote to provide a Timer object. More info is available in the comments at the top of event-timer.js, but here's a rough example of how to use it:

    load("event-timer.js"); // Loads the library
    var t = new Timer(); // Instantiates a timer for your script

    // Add an event to your timer:
    t.addEvent(30000, true, console.print("LOLDONGS"));

    /* As your script loops, you'll need to cycle the timer to have it run any
    pending events. */
    while(stuff is happening) {
    timer.cycle();
    }

    Using the Timed Events section of the External Programs bit in scfg.

    Secondly, is there a standard way for SBBS apps (doors, utils and
    other things) to store arbitrary data in a database style format?
    I cannot find anything in the API documentation that looks like
    it's supported.

    There's the JSON DB (json-db.js) and RecordFile (recordfile.js)... though I'm not sure what you mean be "database style format". There's also the ini bits of the File class.

    The SQL patch is probably the most appropriate tool for what I'd like to

    The patch used to be hosted here: http://bbs.docksud.com.ar/~ragnarok/sync/js_sqlite/
    but the file appears to be missing now... get ahold of Ragnarok (Synchronet sysop) and see if it's still available somewhere.

    by "database style format", I meant just anything that isn't flat text
    and is somewhat index-able. Doesn't need to be much more than a
    persistent hash so JSON DB sounds like it would be the best option.

    setTimeout is not defined? How does one go about executing
    timed events?

    on http://www.roughneckbbs.com/Downloads.aspx download, and look into the S3 shell... basically all the input prompts are doing a 1 second timeout, then checking for other stuff (this allows for inbound messages at a command prompt).

    Secondly, is there a standard way for SBBS apps (doors, utils and
    other things) to store arbitrary data in a database style format?
    I cannot find anything in the API documentation that looks like
    it's supported.

    Depends on what you need... if all you need is a key/document store... you can create a directory for your app's data, and put ####.json files... JSON.js should work fine for serialization/deserialization.

    If there isn't... what are other people using for their persistent
    data stores for extensions to and doors for SBBS?

    generally people are using text configs, serializing json, doing something custom, or shoe-horning in a database client driver... I wrote a connector
    for ADO.Net requests at one point... at the time I was using XML, before a version of spidermonkey with E4X support, or for that matter the boom of JSON... didn't perform well enough at the time.. ymmv.

    With Ragnarok's sqlite patch? I have no idea, I don't see the patch anymore, so
    that's a question for Ragnarok.

    I've updated your patch to work with the latest CVS source.. along with dealing with updating some calls which are now obsolete in mozjs. I'll
    forward you a copy once I've finished testing it.
