I've been using the WEE Editor by Pete Eberlein and much prefer it to ed and others I've tried in the past.

My only 'wants' to improve my editing process would be for the editor to remember position and size between executions and to have a 'recent files' list. Other than that it seems to be a solid editor and I really enjoy using it.

FWIW ... your mileage may vary.

I'm not a fan of futzing with the Windows registry so I'd vote elsewise.

One more favor ... line number (column numbers would be nice but finding an error without know what line number I'm on is a bit of a pain). Don't need a left margin column of line numbers, the current line number displayed somewhere on the screen would be sufficient.

I use Visual Studio 12 a lot at work and, although not a Micro$oft die-hard fan, their interface does have some nice features.

And NO RUSH! At your convenience :)

Hmmm ... I think we could come up with a better name for the editor. Wee??

Ok, so you mean 'little', so why not lee (little euphoria editor)?

Something else for down the track: scriptability of the editor using Euphoria.

Kind regards,

BTW, I'm now getting wee_conf.txt files everywhere where I've edited a file. Is that deliberate or should the conf file hang with the binary or in some subfolder of %USERROFILE%\AppData ?

Another BTW: if you edit a non-eu file and then F5 it, not only does the file not run, but it kills wee as well.

Not really, it seems to be an internal limitation to the richedit control. It sends the message when the richedit buffer needs to be enlarged, but the text you were trying to paste or type still gets truncated. Not sure how to fix it yet.

I made some fixes to the ShellExecute, it should work better for any document type, as long as the file associations exist.

Appdata is used for the wee_conf.txt now.

Get it here

I also noticed that Jean-Marc DURO posted an update to WEE last week, with some useful new features. I should have started with that as the base, but I could try merging it with his permission.

VERY nice work. I just associated the mLite interpreter with .m scripts (as below in an admin shell), edited a script, pressed F5 and got the right response from the mLite interpreter. Now all we need to do is detect a crash and parse the error, and be able to pass parameters to the script.

ftype mlite=c:\bin\mlite.exe -i - -f "%1" %* 
assoc .m=mlite 

Suitably impressed,

Hi Jean-Marc,

I got your updated editor in my email, thanks. I see you put the subroutines in a list on the left side of the editor window. I had intended for the View Subs F2 option to pop up a list dialog and selecting an item moves the cursor to that subroutine. If you've ever used old QuickBasic, it works similar to that.

You can try it out here.

After changing includes to get it running on OpenEuphoria 4.0.5, I get errors when run:

'SystemParametersInfo' (WEE.EXW:663) has not been declared. 'SPI_GETNONCLIENTMETRICS' (WEE.EXW:664) has not been declared. 'CreateFontIndirect' (WEE.EXW:669) has not been declared.

I will have to find correponding declarations to try it out.

Regards

Jean-Marc

I didn't realize that wiew_subroutines pointed to the right line in hedit.

I took your last version with minor modifications for my needs:

• status bar Microsoft way
• run_start from the previous release because .ex and .exw are associated with the editor and not with ex or exw
• fixedsys font (I'm getting old)
• includes and syntax coloring for OpenEuphoria 4

Thoses changes are in the release I sent you yesterday.

Yet I have my new Euphoria editor in replacement of Mike's editor (Medit) which is not adapted to OpenEuphoria 4.

For Linux, I use wxEditor.

Best Regards

Jean-Marc

Sorry about the missing functions, I forgot to drag window.ew to the zip file. Jean-Marc, you have the correct fixes. I was trying to make use anti-aliased fonts for the dialog buttons and cursor position.

I updated the wee.zip in my dropbox.

There's a few things I would still like to add:

• select editor font and put it in conf file
• autoindent new lines
• multiple file open (tab control?)
• syntax highlighting on the fly

As issued "Start" on the "Run" menu calls ex or exw for Euphoria code, picking up the links from "run_extensions". I have added to my copy a submenu of "Run" to enable the user to select OE4 options instead, thus widening the scope of the editor and making it more likely that a new user will adopt it. There is, indeed, a case for changing to OE4 only, if that is the main purpose of the updating.

25. Re: Editor

I feel this is already handled well enough by the View->Goto Error F4 option - it shows a MessageBox with the error message and moves the cursor to the line with the error.

I dislike having line numbers on the side, and other visual noise, but if you can strongly persuade me and suggest an easy way to do so, I'll consider it.

I would very much like to have a look, please email it to my gmail address, if you don't mind. I have my own ideas on how to handle the parsing and symbol table, but it would be nice to have a starting point. I'll have to investigate the namespace and forward references in 4.0 as well, since my mind is still set in the 3.1 ways.

Something else nice to have: detection of the file being changed while the editor is running. I just had a file opened which I edited in wee on my machine and then via RDP on a server. As it was, no big deal that I saved over my changes. But it could have been a big deal.

Kind regards,
bugmagnet

Looking at the example your link provides, http://msdn.microsoft.com/en-us/library/windows/desktop/aa365261(v=vs.85).aspx , it seems that using a helper child process (a helper program that simply runs, waits on a single file passed on its command line, then somehow asychonously signals the parent process when the wait is over) should work too. The IPC part would be a pain, but it's not like you have to share memory addresses between two different threads of execution in this case...

Checking the files on window focus is what I went with. Not perfect, as it gains focus when its own dialog windows are closed, oh well. It also watches for ex.err too in the same directory as the most recent file run.

Download here

There's a weird bug with saving the recent files positions, it's driving me nuts. Please ignore the new non-functional View menu items for now, not implemented yet, but I'm working on it.

Okay, I have that and a few new things, so I figured an update was in order. I took the parser from the interpreter I was working on back in May and made it handle most of Euphoria syntax, producing a full AST with symbol location and scope information. With this I have implemented Goto Declaration (Ctrl+F2) and Code Completion (Ctrl+Space). It only works for the current file, and it doesn't handle includes or namespaces yet. I haven't tested it too much, and it may crash the editor, so I made a crash routine for saving your files. :)

Syntax coloring worked under wee 05 - lost in subsequent versions.

Good luck with your project!.

I agree, there should be a way of stripping the formatting of code that is pasted into a RichEdit control. I tried doing EM_SETTEXTMODE, TM_PLAINTEXT but that didn't help, and it caused the problem Ken found running it in Wine. I then failed to find way to get notified when the text is modified, and the character range of the modified text. I keep getting the impression (over and over) that the RichEdit control is a poor choice for an IDE. Is the wxWindows edit control any better?

I've made some progress on include files and namespaces, and I think I've got them figured out now, I'll post the code once I have done more testing. This covers the first item, and the editor now shows all declarations in visible scope for autocompletion, and can detect undefined symbols.

For the second item, the editor should, on startup, parse all the includes in the default include directory and make a list of the library routines for highlighting (this is why I've not updated them for 4.0 yet). I just realized that I'll need to add support for "ifdef", "elsedef" and "end ifdef" to parse OE4 std includes. Is there a way at runtime to dynamically know what keywords are defined? I don't see how, maybe I'll just hardcode a list.

For the third item, when do you want to be presented with the list of includes? On autocompleting symbols, view declaration or a third new option "view undefined references"? Or even as you type? (would need the change notification working for this)

I really should put this project on github so that you can file tickets, forks, and pull requests. :)

You may want to crash more gracefully than this:

Sorry it's been so long since the last update. I have finished switching over to the Scintilla edit control, and finally got things working as well as before with the RichEdit control. Thanks to the Scintilla lexer, the syntax highlighting now updates automatically, though I cheated and used the Lua lexer instead of writing a custom one for Euphoria. The View Declaration (Ctrl-F2) and Auto-completion (Ctrl-Space) now work in include files, and auto-complete will suggest routines from the standard library includes. The first auto-complete will have a slight delay while the include directory is parsed, but are cached from then on. The autocomplete uses the Scintilla list popup, which is niftier than a modal dialog. Also pressing Shift-F2 on a subroutine call should popup a CallTip with argument types and names, with default arguments in square brackets; eventually I'd like it to pop up automatically and highlight the argument position of the cursor. I apologize for any bugs or crashes, there's still a lot of polishing to do.

David, thanks for testing, and I'm sorry you had a problem with it locking up. If it happens again, please get a screenshot so I can see what was typed that got it stuck. To try to fix the problem with the window not appearing, try deleting the file /Users/Username/AppData/Local/wee_conf.txt. Maybe the window size was saved to zeros?

Hello,

I'd like to ask a question about how to open and run wee in Windows.

I've got Eu4.0.5 in c:\euphoria
I've unzipped wee to c:\euphoria\wee (Is that the best place to put it, BTW?)
I see wee.exw and two include files (syncolor.e and window.ew)
I open wee.exw and can enter some code, but I don't see any syntax highlighting or autocompletion.
Can someone please tell me what to do next?

Thank you,
Alex

Alex, I wasn't able to figure out what the problem with the font size was. I did made it update the editor windows after a change, so hopefully that was the issue. If not, look at the contents of \Users\yourname\AppData\Local\wee_conf.txt after changing the font and closing the editor.

Evan, this version fixes the crash with Ctrl-Space on whitespace, among other things.

Why not choose some available advanced editors for each platform?

Like eg Kate under Linux.
and EditPlus under Windows

The only thing we would have to do
is write a table of commands/functions/constants etc. for it to make it work perfectly.

The scintilla DLL is 32-bit, so that's why it can't load in x64 Euphoria. The code WEE is based on makes many assumptions about running on 32-bit, so it won't run on 64-bit without modification. There is also a bug in the 64-bit Euphoria releases before Nov 2014, where pointer arguments to a callback get truncated, I'm not aware of any fixed releases yet. In short, please use 32-bit Euphoria.
