原本是在找 vim 啟動時間相關的資料,找到了 這個網站 ,
發現有 --startuptime
這個參數可以用,於是就立馬來試一下,
vim --startuptime vim.log test.py
接著就可以去 vim.log
看整個啟動狀況

manual in Vim : :help slow-start
這個 log 參數剛好拿來解掉一個朋友碰到的問題 ~
他在用 mosh
連到某台機器上開 vim 時會 hang 住,
藉由這個 log,發現是卡在 clipboard 那裡,
原因是因為程式嘗試和 X server connect,但一直連不到,
接著就找到了解法 vim -X
