vimdiff 展開 收起 diff sections

https://stackoverflow.com/questions/5288875/how-to-expand-collapse-a-diff-sections-in-vimdiff



Keyboard Shortcuts:

d o Get changes from other window into the current window.

d p Put the changes from current window into the other window.

] c Jump to the next change.

[ c Jump to the previous change.


CTRL+W, w - Switch to the other split window
(CTRL+W, CTRL+W does the same thing, in case you let go of the CTRL key a bit later)



:diffupdate :diffu -> recalculate the diff, useful when after making several changes vim's isn't showing minimal changes anymore. Note that it only works if the files have been modified inside vimdiff. Otherwise, use:

    :e to reload the files if they have been modified outside of vimdiff.


:set noscrollbind -> temporarily disable simultaneous scrolling on both buffers, reenable by
:set scrollbind and scrolling.



Most of what you asked for is folding: vim user manual's chapter on folding. Outside of diffs I sometime use:

    zo -> open fold. 或是按方向右鍵
    zc -> close fold.

But you'll probably be better served by:

    zr -> reducing folding level.
    zm -> one more folding level, please.

or even:

    zR -> Reduce completely the folding, I said!.
    zM -> fold Most!.

【漢字擷趣】從十分到十二萬分

有個外國留學生感嘆道：「漢語真是博大精深。我發現漢語喜歡用數字表示程度，例如十分、十二分、萬分、十二萬分，這幾個詞都表示非常、尤其。這幾個數字相差很大，漢語裡它們卻成了同義詞，有了一個神奇的等式，十分=十二分=萬分=十二萬分。真是把我們這些老外搞糊塗了。」

IPsec Transport Mode with strongswan on Debian 8 Jessie
Posted by Christoph Haas on 10 03 2016. 1 Kommentar zu IPsec Transport Mode with strongswan on Debian 8 Jessie

Today I am going to write a small tutorial on how inter-server communication can be secured via IPsec in transport mode. This tutorial was written for Debian 8 Jessie but it should work similar with other linux distributions aswell.
