git + long xml + chunk

Hi, Please give me some advice how I can manage that situation: I have a win10 and a 34500 lines long xml file. It's an ssis package but it's not important. I would like to check the modifications and enable / chunk. Magit dont' working because I need to wait \~5mins to show something but it's too much to calculate the stylish ui ... The vc dont' know to add git commit / chunk git -i is ugly what do you use in this situation ? What is you trick ? thanks for advance

I can answer it: ediff with e. Fast as I expected :) For somebody who look for a solution for this problem: if the "toggle-section" is slow then you can press the Ctrl+g a lot. In this case you can press the "e" on the file. The ediff buffer contains 3 buffers: - left: the unchanged / commited state of the file - right: the modified state of the file - center: the staged state of the file You can use the normal keys to reach that: - "ab": unstage a staged hunk - "cb": stage a hunk If you finised the preparation just press the "q" and answer "y" and "y" instead of write the changes to somewhere...
