Is there a way to modify the cloze plugin code to cloze like this??

I'm curious: What do you need this for: For what area of knowledge, what kind of cards? I assume your example with years is just an example ...

I'm not sure what you want: The examples you give you get one cloze for each character. Splitting a string after each character is not too hard so this should be doable.

But in your description you ask for splitting by "each syllable". That's much more complicated because the computer doesn't know what a syllable = a combination of letters is. There are external libraries that do this quite well but I'm not sure how this works in different, especially asian languages. How exactly do you want to have it split.

Why do you mention the space bar cloze addon. Just to tell us that you prefer ctrl+space over ctrl+shift+c or does this addon any additional functions.

soon a major new version named 2.1 will be released. Addons for the current version won't work. Many addons have already been ported but not all. So you could say if you need it for 2.0 or 2.1.

I modified an existing addon. For me it works in 2.0.52. I'm not a programmer so use it at your own risk.

Important rule: Make sure to have a proper backups (like in the 3-2-1 rule) and you only know that a backup works if you have tried to restore it. So try to restore some data.

Put an empty file in your addons folder with the extension ".py" (like cloze_each_char.py) and put the follwowing code inside this file. Then restart Anki.

I used F2 for multiple clozes and F4 to not increment

    for c in text:
        if state == "increm":
            number += 1
        new += "{{c" + str(number) + "::" + c + "}}"    
    self.web.eval("document.execCommand('inserthtml', false, %s);" 
            %json.dumps(new))

def setupButtons(self):
    self._addButton("cloze_each_char", lambda s=self: cloze_each_char(self,state="increm"), 
                    text=u"cli", tip="cloze each character (F2)", key="F2")
    self._addButton("cloze_each_char", lambda s=self: cloze_each_char(self,state="fixed"), 
                    text=u"clf", tip="cloze each character fixed (F4)", key="F4")

Editor.cloze_each_char = cloze_each_char
Editor.setupButtons = wrap(Editor.setupButtons, setupButtons) 

With Ctrl+Space this didn't work. So I modified a different addon. This seems to work for me.

You could report if these work for you and if not what error message you get.
