Description pinggi 2012-06-02 14:42:11 UTC
Let's say I want to write 'List<int> list = new List<int>() definition.

1. So I start writing...

L

2. Now the popup window displays the list of possible choices. I continue...

List

3. Now the popup window shows 'ListMnemonicLabels' as the current item. I continue...

List<

4. Now the popup window disappears and it ends up with...

ListMnemonicLabels<

5. I wanted to write "List<" and I end up with "ListMnemonicLabels<". Grr.

6. I need to remove "MnemonicLabels" to be able to continue with my writings.

This happens because there isn't "using System.Collections.Generic;" on the top of the file.

However, the common scenario is that you write 'List<int>' and then press a shortcut key, which generates using statement automatically. It is not possible in the Monodevelop.

control+alt space solves that;

you can do List<int> list; and then right click on list to add the namespace as well.
If there isn't the item in the list you have to cancel the completion list with escape.

Mike, I reopened this bug. 

For me it is a bug, because I wanted to write "List<int>" in the text editor manually and text editor writes different text.

control+alt+space doesn't solve it!


I don't look at the screen all the time. Also think, the context menu should help me, not push me to choose something from a dialog. It stops me from writing a code.

I try to explain it again.

1. I want to write "List<int> list = null;" by my fingers manually without looking at the screen.

2. After I write it, it ends up with "ListStore<int> list = null;". Why? I don't want to help, because I know what to write. ButMonodevelop text editor changed my text, so I had to go back with cursor and delete it!

I have attached screenshot situations. You can look at that.

My opinion is that the text editor should write keys which I press. If I need help, I can ask by 'ctrl+alt+space' or by pressing 'tab' key to complete a word.

If I write 'List' and then press '1', it doesn't complete the word, so why it should complete the word if I press '<'? It chooses possible words or statements from the popup list. So what is the problem with selecting right word in the popup and pressing the 'tab' key or the 'enter' key? Why should I need to cancel it?

According to me, this is really wrong behaviour. It should not complete the word if you don't want to.


>>you can do List<int> list; and then right click on list to add the namespace as well.

Is there working shortcut for it? I would like to write 'List<int>' and then press 'ctrl+.' or 'shift+alt+F10' or another to automatically add 'using' statement. I don't want to use mouse if I'm writing a code. It is slow to move hand to mouse and move cursor to word right click, choose some category, choose right item, click, move the mouse cursor away and move my hand back to the keyboard.

Think about it please before you close the ticket.

This is how completion mode works. If you prefer to type things out-of-order, you may prefer to enable suggestion mode, as explained here: http://mjhutchinson.com/journal/2011/02/monodevelop_tips_suggestion_mode

Wow, really cool. Thanks a lot! I haven't known that.
