Objective
All said that the use of VIM, the programming experience feel silky, but the starting slope is indeed a bit steep, always daunting.
I have previously tried vim more than two times, each time because of confusion of its various modes, a variety of key commands, and use up the total stumbling, each time insisted not more than one afternoon to give up.
But every time to visit some technical community, always see the way the great God inadvertently said a vim, and always feel so powerful things, do not experience, it is regrettable, the heart and itch.
In combination with the current situation:
- Each IDE's shortcut keys are always CTRL, ALT, shift plus other key combinations, key frequency distribution uneven, use more total feel pinky some hair
- Unable to leave the mouse, can not form a smooth workflow, each encoding is working hard, but to do some adjustment, the hands have to stop, the right hand off the keyboard, to hold the mouse, watching the cursor movement, the last point, deep feeling very uncomfortable sense of fragmentation
Here are the main reasons why I feel I have to experience vim:
- I heard that vim itself is very flexible editor, all kinds of powerful functions can be customized out.
- In addition, the use of vim plugin + modern editor, you can use the VIM keyboard flow operation seamlessly switch to the various now editor, will not vim, in exchange for an editor to re-remember its shortcut keys, so it seems that vim although the previous experience may be more painful, but learned that may once and for all, combined, The time to remember shortcuts should be less than the non-use of vim.
- Vim's keyboard flow can not only be used in the editor, based on the concept of the development of various plug-ins, but also in the browser, command line and other places to use, most of the situation basically can abandon the mouse, which for the love of keyboard operation of me is really tempting
So, I decided to start again, fortunately this time finally persisted, recorded this experience.
First I switch to Google search learning resources, and then found something very fun and useful things, such as some sites to learn vim into a game, let you in the game using VIM command operation, this blog list of learning vim some good site.
Finally I chose Vim Genius this website as the study position, it divides vim commonly used several commands to divide several levels, lets you each one to learn, after each learning a level lets you use the keyboard to enter the command which the study commands, each command will repeat several times, ensures that you can remember, And can not skip and can not arbitrarily select the following levels.
My way of learning is this:
- Start by using Vim genius to learn a level and complete the level exercises, and then record the commands you learned.
- While learning to record some of the rules of the command, in fact, the vim of the keys set is regular, find out the rules, can help us quickly remember, and can extrapolate. If uppercase indicates an entire row or a reverse direction, two repeating lowercase indicates an entire row operation, etc.
- Do not rush, not a day to finish the Vim Genius, I think if not solid to do the above practice and record, that refreshed estimate also immediately forget, so I only brush two levels per day, every morning and evening after the meal brush once, so a total of 7 levels, with three or four days to finish the brush
- After the vim genius after the actual combat, I use
idea+ideavim插件 as a combat position, first of all, start with the requirements do not high, first learned the most basic operation, can be deleted and modified, copy paste can, do not think of vim as the God to save you, but first to use Vim as an ordinary editor
- Learned the basic operation, encountered still not easy to check the relevant commands can, slowly progress
Using the above method, first in the Vim genius brush three or four days of basic commands, and then bite the teeth to stick to the actual combat three or four days, a week end, at this time using vim, at least to achieve the efficiency like with Windows Notepad, is a basic introduction, and then slowly learn advanced features faster.
Look back. Vim is no longer a high mountain from which to begin, but a smooth slope to see a path through
In the end, I was told the order of my record and the rule of summary, the wrong welcome pointed out.
- Note: Use
- number as a delimiter for interpretation and command
Law
- Uppercase indicates the operation of the whole row or the opposite direction
- Two repeating lowercase indicates an entire row operation
- The quantity is placed in front of the command unit to complete the bulk operation: Each individual command can be done, can be called the command unit, such as the unit of a single word, DD units for one line, you can add a number in front of the command, so that the batch operation, such as 3w, 2dd,d2w, where d2w, the number 2 is W, Indicates that the action Unit is W (word) and the action is D, so that 2 words are deleted
- Select Word: Select from the cursor position to the end of the word, not from the first character of the word
- ^ denotes the beginning of a line character, and $ denotes the trailing character
- L means backwards (last), h means forward (head)
