Oeasy teaches you to play with VIM – 76 – # key combination map

Session session

Recall the details of key combination mapping

• Last time we defined a series of composite keys

  • Mainly with the CTRL key

• Quick jump window

  • map <c-j> <c-w>j
  • map <c-k> <c-w>k
  • map <c-h> <c-w>h
  • map <c-l> <c-w>l

• Quick jump tab

  • map <c-left> :tabn<cr>
  • map <c-right> :tabp<cr>

• You can also work in line

  • map <c-s> :%s/5.1/5.2/g<cR>:wnext<cr>

• Finally, pay attention to the small details of the notes

  • :unmap a|" unmap a

• The combination key is the same as the function key FN

  • Can do all kinds of mapping
  • Mapping map and abbreviation abstract are the same as folding and local options
  • Can pass:mkview、:loadviewTo save the read
  • But if there is a tab in my environment
  • There are also various windows with good segmentation in the tab
  • When you wake up, you have to cut it again
  • We have to start again:tabnew
• I want to store the status of multi tab tabs and multi window windows
• Is it possible?

Search process

• IfWith this function

  • It must be:mkviewnearby
  • Let’s go to the scene first
• :h mkview

• viewThe inside can include

  • parameter list:args
  • Current file

  • viewoptions

    • Map map
    • Abbreviation abreivate
    • options
  • fold
  • Scroll position and cursor position
  • Current folder
• andviewoptionThere is one relatedsessionoptions
• < C -] > go in and have a look

• fromtabsreachwindow
• Fully meet the demand

Save session:mksession

• :mksessionSave session
• Where did you save it?

• :echo this_session

  • The answer is saved in the current directory
  • be calledsession.vim
  • This is like saving a workspace in the root directory of the project
• Let’s see what this thing is?

Session content session

   git clone http://gitee.com/overmind1980/oeasyvim.git`
   vi -o oeasy.java oeasy.css oeasy.html

• Then create some tabs
• :mks[ession]

• You can see this in the sessionoption

  • tab
  • buffers
  • window
  • All of them
• 1000 + lines in total
• Saved the current state

• When you want to recover, just

  • :so[urce] session.vim
  • It all recovered

Switch project workspace

• You can create two sessions
• Then copy oeasyvim and call it oeasy

• So we have two working folders

  • For example, oeasyvim is task a we don’t want to do
  • Oeasy is Task B we want to do

   cd ..
   cp oeasyvim oeasy
   cd oeasy
   vi -o oeasy.java oeasy.css oeasy.html

• Plus some tabs and so on

  • again:mksession
  • This time, it is established under the project folder of oeasySession.vim
  • We can see these two projects
  • Each has its own engineering documents
  • That is, each has its own blue cotton curtain
  • You can even share the workspace status online

• Others will use your layout to open your project

  • vim -S Session.vim

• Or after entering VIM

  • :source Session.vim
• You can also make different faceted conversations for the same project

Project workspace folder./sessions

• :mks ~/sessions/oeasy.session

  • You can specify the location~/sessionCreate project directory under

  • All project documents are stored in the project directory

    • ~/sessions/oeasy.session
    • ~/sessions/o2z.session
    • ~/sessions/o3z.session

  • In this case, I can go directly to the project directory to find the project

    • ls ~/sessions/
    • vim -S ~/sessions/oeasy.session

• advantage

  • Centralized management of each project
  • You can also set these session files

  • In fact, there are other ways to prevent session files from appearing in the project directory submitted by GIT

    • Use Gitignore can solve this problem

• shortcoming

  • To delete a project, you need to delete it in two places
  • Engineering program material and engineering work area are not together. It’s troublesome to copy and paste

Function key mapping

• I want you toF2Can execute:mksessionTask

  • :map <F2> :mks!<cr>

• I want to save the file before I save the workspace

  • :map <F2> :wa<Bar>mks!<cr>

• I want to save the file first, and then save the workspace to the current session file

  • :map <F2> :wa<Bar>exe "mksession! " . v:this_session<cr>
  • Where V: this_ Session is the current session
  • sure:echo v:this_session

• When you want to load a session

  • :source ~/oeasy/oeasy.vimYou can also specify a function key
  • :map <F3> :source ~/oeasy/oeasy.vim<cr>

• WhenF3When

  • The session is saved
  • The two map maps are saved in the session

View and session

• order

  • VIM must have existed first:mkviewSave window view
  • Later:mksessionSave entire session
  • This shows that VIM becomes more powerful
  • More suitable for multi-threaded concurrent environment

• Relationship between the two

  • Projects with single tab and single window can be used:mkview
  • Multi tab multi window window project is best used:mksession
  • :mksessionReplaceable:mkview

• But in the last paragraph, he said

  • viewandsessionAllviminfoA useful supplement to??!
  • What do you mean?
• Let’s summarize firstSession

summary

• This time we definedsession

  • :mks

• You can also load sessionssession

  • :source Session.vim
  • vim -S Session.vim
• Basically established:mksessionCan replace:mkview
• Who knows, another one came outviminfo?!😨
• These two brothers have become a useful supplement?
• What happened?
• Next time!
