Hi, An open issue for this topic[1].
This email details how I want to add line numbering to IDLE. The mock is at [2] This will be only added to EditorWindow and OutputWindow. The tk.Text class will be replaced by a Text class which inherits from tk.Text as in the mock(line 50). Basically, a virtual event called <<changed>> is going to be generated when the following actions take place: insert, delete, replace, when 'insert' is changed, the window moves etc. The Text object will intercept this call, trigger <<changed>>. It will propagate the original call, as well. The line number canvas will be at the left of the text area. It will be redrawn, whenever the above events take place. I was worried about memory usage due to constant redrawing, but the memory never increased beyond 5.3 MiB. This is good, given a text widget on its own takes 5.0 MiB. Processor usage was same in both cases. As far as details like background, color of text etc are concerned, they will be added to config-highlight.def. There will be a menu option to toggle the line numbering canvas on-off. Would something like the "Code Context" option in "Options" menu be good? The open issue[1] says it should be enabled by default. That to me seems like the right way to do it. But if we were to do it as an extension, will the existing extension mechanism allow it?(Especially the tk.Text overriding part). Could someone familiar with the mechanism could fill me in on it? Should the linenumbering related code go into a new class and the Text widget be imported from there, or should it be added into EditorWindow itself?(LineNumber canvas, the interception mechansim etc) --- [1] http://bugs.python.org/issue17535 [2] https://bitbucket.org/sahutd/linenumbering-mockup/src/d311c81a6fbcfa10d125279d616fb90c9745aab6/line-numbering-mockup.py?at=default -- Regards Saimadhav Heblikar _______________________________________________ IDLE-dev mailing list IDLE-dev@python.org https://mail.python.org/mailman/listinfo/idle-dev
