Event scripts!

This feature will be available in version 2.3

Hi guys.
It's a long time i want to introduce a feature like this.
You know you can use template macros for much more than just painting web pages: you can load and save files, run programs, etc.
Why limit this potential to the template? So, don't!
From next 2.3 beta build you will be able to use your editor to make a file named "hfs.events" (next to "hfs.exe").
Using the same syntax as the templates one, you'll be able to DO things when some events occur.

Example

Code: [Select]

[connected]
{.disconnect.}

This will prevent any access to your HFS, because any connection will just be disconnected. Quite useless, i know, but it's to keep the example easy. You can be selective over disconnections by using other macros.

Another example, this will limit to 10KB/s every file with "hey" in the name

Code: [Select]

[download]
{.if|{.is substring|%item-name%|hey.}| {:
  {.set speed limit for connection| 10 .}
:}.}

Currently supported events are: connected, disconnected, request, download, download completed, upload completed.
As you can see from the examples, new useful macros are coming, designed with events in mind.
Stay tuned for the next beta in the "beta" forum.


Suggestions?

Hi

Sounds great.
First thing I thought reading while "Events" was zFTPServer Suite.
This freeware FTP-Server has Events allready included. Maybee you (we) find there some things and hints for v2.3?

Thx for developing HFS in this great way,

Just a little post to say to you that for some time I had the same idea on this principle, but I above all have to look at sources to understand  the new functioning, and push more forward my investigations.
[on_connect]
[on_disconnect]
[on_loggedin]
[on_upload-failed]
[on_ban]
[on_deny]
[on_unauthorized]

some other suggestions

[on_start]  //every time server start

[on_stop]  //every time server stop

[on_run]   //every time hfs is running

[on_close]   //every time hfs is quitting

[on_upload_success]  // every time an upload is finished
{.if|{.exec|scanvirus.exe|%upload-filename%.}
     |{:{.delete|%upload-filename%.}:}
     |{:{.exec|md5 calculate.exe or update mp3 info.exe or ... .}:}
.}
[on_low-disk-space]

.... à suivre

[rejetto]

i added: start, quit, upload failed.
loggedin doesn't really exist until we use http authentication.
other events will be added as we see they are useful, no need to overdo.

[Mars]

MAIN.PAS

updateEventScripts() into the procedure everyTenth()

As hfs.tpl , hfs.events is relaoded every time his date change.

Can you add a fast shortcut to edit  the hfs.events as follows

procedure TmainFrm.EditHFSEvents1Click(Sender: TObject);
const default='[start]' + CRLF +CRLF +
              '[quit]' + CRLF +CRLF +
              '[connected]'+ CRLF +CRLF +
              '[disconnected]' + CRLF +CRLF +
              '[download]' + CRLF +CRLF +
              '[download completed]' + CRLF +CRLF +
              '[upload failed]' + CRLF +CRLF +
              '[request]' + CRLF +CRLF
              ;
begin
if not fileExists(EVENTSCRIPTS_FILE) then
  begin
    saveFile(EVENTSCRIPTS_FILE,default);
  end;
exec(or_([
  nonEmptyConcat('"', tplEditor, '"'),
  loadregistry('SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\notepad++.exe', '', HKEY_LOCAL_MACHINE),
  'notepad.exe'
]), '"'+EVENTSCRIPTS_FILE+'"');
end;

I was again going to forget a thing as usual: thanks.

If those this sometimes miss in my demands, they are always in my thoughts, face to face of you it goes without saying

[rejetto]

Ok, in next build

[Mars]

Following stage and not the slightest:

To differentiate the events according to the used folders, mainly there upload, it would indeed be necessary to be able to use in a real folder the usage of a hfs.diff.events.

DIFF_EVENTSCRIPTS_FILE = 'hfs.diff.events';

It is easier to manage certain events individually and with many differences according to the used real folder

Only some events will can be defined in these diff events (upload, download,.....), but not those who are bound to the functioning of the server (start, stop, connected, disconnected,...) because here they would have no action valid and could interfere with the main hfs.events

I hope that these some explanations will be enough. (Rejetto, I had no time(weather) to tilt me on the programming, because I preferred to put the idea on the paper before forgetting it, and I already have my small idea on the question). Good courage

So macros are here to stay... Fu*k, imgetting to old for this shit. And i only in my best 30`s. That IS crazy.maybenot
Ive said it before, the sky is the limit.
quote
"life is what`s happening while you are planning tomorrow"
I have a suggestion:  Can you make a event like: [on_filesize_increase] or [on_write_to_file] or [on_incremental_overdrive]
Scenario:
If i attach a photosensor to a camera. Then the camera start write to a file. That file is hosted by hfs, and hfs will trigger the event. My phone is pip-pip-ing. I`ll go online. And watch the latest release.
An other ting that would be really cool, is to make any of those events play a sound, or even send a mail.
Rock`n`roll rejetto, im going to a Paul Van Dyk "concert" Saturday

An other ting that would be really cool, is to make any of those events play a sound,

Working since build 176

{.play system event|sound_system_event_name.}

( example {.play system event|systemstart.} )

or

{.play system event|c:\........\your file.wav}

I was afraid so thx mars
..we should have a lexipedia or somethig.

  What!! 1 7 6 ? ..that is a long time ago.  ok..

now, this works on my personnal version

[rejetto]

..we should have a lexipedia or somethig.

i try hard
www.rejetto.com/wiki/index.php/HFS:_Template_macros#Full_list

[Fysack]

lol so that is macros. Just like logic gates. No wonder why people fear them 
Its a great wiki rejetto, it pull`d me true many times. When i say lexipedia, i meant something more like a alphabetical list of all the things you can do with HFS. FAQ style maybe. Tutorialic. My point is: how can you search for something if you dont know it exsist.
Ok, maybe not a lexica, but a collection of tips & tricks. Cool things to do with your HFS
This would be a great topic:
Tips,Tricks & Cool things to do with your HFS.
If the reason was not that im extremly tired right now, i would make it myself. So if anyone wake up before me, feel free 
Peace
