External editor for CodeWarrior

[OS923]

I'm preparing to write an external editor for CodeWarrior. You may post your feature requests here.

[OS923]

The AppleScript support is finished.

[Protools5LEGuy]

You may post your feature requests here.

XCode wrapper. Converts XCode code in CodeWarrior code thanks to QuartzToQuickDraw converter and other compatibility layers.

[OS923]

It's meant for OS 9 only.

CodeWarrior keeps the text in memory as one block just like the data fork. This is not performant, although it can scroll 4000 lines per second.

Features that I want:
- max 32767 lines. This corresponds to the max value of the vertical scrollbar. The value of the scrollbar will then be equal to the number of the line on top of the window.
- the last line can be scrolled to the top of the window without having to append empty lines.
- no horizontal scrollbar.
- no C comments.
- automatic indentation like in REALbasic.
- more choice for syntax coloring.
- faster multiple undo.
- faster search and replace with regular expressions (RE or RE2) and undoable.
- plugins (sort, uppercase, etc), in other words: scriptable in C++ instead of AppleScript.
- switch to a graphical mode where your code is drawn as colored blocks that can be moved around.
- correction of expressions, for example (a!=nil) becomes (a), (a && b==1) becomes (a and (b==1)), a+b<<1 becomes a+(b<<1) and (a and b or c and d) becomes ((a and b) or (c and d)).

This looks like much work, but when it's finished I will save much time.

Absolutely love the project idea, OS923! In regards to features, nothing comes to mind that you had not yet covered. But consider me a definite "customer" for any alpha or beta. :-)

[OS923]

I changed PowerPlant's Document application into an external editor. This works for files that are shorter than 32000 characters. It's possible to compile text that hasn't been saved yet.

[lartch]

Hi, lartch here. Is the source code available somewhere? Are you looking for help?

[OS923]

This will be closed source, but there will be an API for making plugins with examples.

[OS923]

I'm still adapting my framework to work with documents.
What it can do already:
- About,
- Open desk accessory,
- New,
- Close,
- Close all,
- Quit.

I wrote my own headers for Navigation services.

I'm doing things a bit differently:
- I don't have a hierarchy of panes and commanders like in PowerPlant.
- I have a class for every Apple event, every menu and every menu item. A program is derived from these classes.
- You can't close a modified document. You have to choose "Save" or "Discard". I do this to avoid an endless list of save changes dialogs.
- You can't quit unless all documents have been saved or discarded.
- You can also "Detach" a specified document to make it unspecified and close the file. This has the same effect as opening a stationary.
- I would like to open multiple Find/Replace dialogs, save them and alternate between them.
- I would like to save interface parts as snippets and editions where the interface is defined as a document which can be saved, for example a Find/Replace dialog.

[OS923]

Some ideas:

• When opening several documents,
  the first comes in front,
  the second behind the first,
  the third behind the second and so on.
  This is faster than when every new document comes in front.
  
• Undo and redo are possible after save.
  

A strange practice in PowerPlant is to write:

LDocument.cp line 210
delete this;

LDocument.cp line 439
delete this;

LInPlaceEditField.cp line 200
delete this;

LMacTCPTCPEndpoint.cp line 788
delete this;

LModelObject.cp line 148
delete this;

LModelObject.cp line 164
delete this;

LRadioGroup.cp line 146
delete this;

LSharable.cp line 146
delete this;

LThread.cp line 1041
delete this;

LWindow.cp line 1263
delete this;

LWindow.cp line 1278
delete this;

LWindow.cp line 2490
delete this;

I add the items to a list and when I'm done, I delete the items in the list.

[OS923]

I wrote a library for Navigation services which is easier to use than StandardFile.
It's the simplest solution that I have ever seen.
All references to Apple events have been removed.
This is now part of the OS 9.3 SDK.

It was originally written in Dutch, and I forgot to replace Lijst with List in some places.
Lijst is Dutch for list, with ij pronounced as e in beta.
