1. Auto Update for WEE?

Especially since WEE is in a constant state of change, have you considered adding an auto-update feature? Notepad++ has a feature like this, and it's pretty cool.

Specifically, the user could have an option for the program to check to see if it's the latest version. If not, it could report to the user that there's a new version available. Additionally, it could give the user the option to automatically update the program.

Of course, that assumes a couple of things:

• You've got a stable place to host the code
• It doesn't cost you an arm and a leg to have a bazillion people hitting that site when WEE becomes popular

I'm thinking that an "auto-update" feature could probably be written as a fairly generic routine, so other programs could use it as well.

Just a thought.

Time for a multitude of developers and a code repo!

haha...

DNS (i.e. host_by_name) is not tasking-enabled, so it will block other tasks.

But the rest of the process can be integrated into WEE using multi-tasking.

Here are the bits of code I added to WEE (in ui_win.e) to check for mock updates.

I needed a function to show a simple "OK" message box.

global function ui_message_box_ok(sequence title, sequence message) 
    atom result 
    result = c_func(MessageBox, {hMainWnd,  
      alloc_string(message), 
      alloc_string(title), 
      or_all({MB_APPLMODAL, MB_ICONINFORMATION, MB_OK})}) 
    free_strings() 
    return result = IDYES 
end function 

Here is the routine that "checks" for an update.

constant WEE_UPDATE_URL = "http://openeuphoria.org/index.wc" 
 
procedure check_version() 
 
    atom task_id = task_self() 
     
    -- sleep for a few seconds before checking 
    -- so we don't immediately bombard the user 
    task_delay( 3 ) 
    task_yield() 
     
    -- fetch the latest version information 
    object result = http_get( WEE_UPDATE_URL ) 
    if atom( result ) then 
      -- failed to check for updates 
      ui_message_box_error( "WEE Update", "An error occurred while checking for updates." ) 
    else 
      -- success, perform additional update steps 
      ui_message_box_ok( "WEE Update", "A new version is available." ) 
    end if 
     
    -- stop this task 
    task_suspend( task_id ) 
    task_yield() 
 
end procedure 

Here we create and schedule the task before showing the window and starting the event loop.

atom check_id = task_create( routine_id("check_version"), {} ) 
task_schedule( check_id, 1 ) 
 
c_proc(ShowWindow, {hMainWnd, SW_SHOWNORMAL}) 
c_proc(UpdateWindow, {hMainWnd}) 

And finally, we add a call to task_yield in the event loop.

while c_func(GetMessage, {msg, NULL, 0, 0}) do 
  if hFindDlg and c_func(IsDialogMessage,{hFindDlg,msg}) then 
    -- this message is handled by find dialog (thanks Jacques) 
    -- it makes the tab key work for find/replace dialogs 
  else 
    translate_editor_keys(msg) 
    junk = c_func(TranslateMessage, {msg}) 
    junk = c_func(DispatchMessage, {msg}) 
  end if 
  task_yield() 
end while 

Nah.

1. Package the update into its own installer.
2. Download the installer to a temporary location (e.g "Downloads").
3. Launch the installer with admin permissions from the editor. ("runas" on Windows or "gksudo" on Linux)
4. If the installer launched successfully (user allowed admin action), then quit the editor.

WEE updater now available. Download it in an empty directory (or an existing wee directory) and run it to download or update the files. It might not be able to update the dll while the editor is running, so please close WEE first. I didn't make it part of the editor for this reason, and I want the user to be able to control when it gets run.

How it works: I created manifest.json file with a sequence of the files in WEE, including the file hash(), github commit tag, optional 32/64 bit flag, and platforms supported by the file. To make the manifest.json file, I run manifest.ex > manifest.json to calculate the hashes and commit tags, and then pushed to the repo.

The updater.ex downloads the manifest.json through rawgit.com since that allows me to download it through http_get() using http instead of https. I have to use a .json extension since rawgit.com has a whitelist of allowed extensions, otherwise it will just redirect to https. Then it uses the file hash to determine if the existing file need to be updated. Outdated files are downloaded from cdn.rawgit.com for speed, and the git commit tag in the URL allows the cdn to cache each version separately.

Something I should have asked for in the auto-update: A changelog!

Specifically, some why of seeing in WEE what the latest changes are. Having an option in the Help menu could load the change log, and it could automatically be loaded when the updater is run.

It's not a biggie. The main thing it that it stops me from asking for things that are "broken" in WEE when they simply haven't been implemented yet.

Plus, it reminds me to try out new features I didn't know about.

I haven't seen the GTK include file -"ui_gtk.e" right?

OK, your right this is the error message I get after running updater.ex with eui:

home/kenneth/euphoria/include/std/error.e:52 in procedure crash()  
You need a newer 64-bit Euphoria with callback bug fix  
 
... called from /home/kenneth/Programs/old_progs/euprogs/wee/wee-0.16/wee-0.16/ui_gtk.e:28 in function check_callback_func()   
 
^^^ call-back from external source 
 
... called from /home/kenneth/Programs/old_progs/euprogs/wee/wee-0.16/wee-0.16/ui_gtk.e:34  
 
--> See ex.err  

So, I hope 4.1.0 beta comes out soon!

I'm very, very impressed with your updater.ex, Pete!
