Add last modified buffer (gm) #3814
Conversation
Behaves similar to vim ^ such that it jumps to buffer that was modified. Internally, it keeps two last modified buffer, it behaves like a stack and push the buffer when there is a new modified buffer and it also prevents both last modified buffers pointing to the same buffer. This broke my workflow a lot so I came in and write some C++, hopefully I got it correct. Fix mawww#3607

Solid feature. I've only looked into the implementation superficially, but here are some remarks:
|
If there is only one pointers, if we switched to another buffer without modifying the current one, it we always jump to the original one. If say the second buffer is the previous modified file, it should jump to the same file? So we need two buffers to jump between alternative modified buffers as we cannot guarantee that the buffers are always modified when we change buffers.
Err, I tried using history but I didn't get that method working, we need a sentinel. Say if we changed many files, you happened to jump from one of the files that was previously modified but not one of the last two pointers, if would jump to that file even though that was modified after many modified buffers jumps.
No, having the sentinel does not impact that, if we chose two change the history like vim default |

Should we add changelog for this? |
