Hw03-Vim Editor

1. Complete vimtutor

lee@ubuntu:~/class/Missing-Semester/class-3$ vimtutor

Vimtutor is a simple tutorial for the beginner to learn how to use the editor with the most easy way. After I've been read about it, it pointed that vim need to learn in a long way.

2.Setting the basic vimrc

First download the file to the directory of you user.

lee@ubuntu:~$curl https://missing.csail.mit.edu/2020/files/vimrc > .vimrc

There is something by default as the vim started.

3. Install and configure a plugin ctrlp.vim

Install with the following commands and use it.

lee@ubuntu:~$ mkdir -p ~/.vim/pack/bencor/start
lee@ubuntu:~$ cd ~/.vim/pack/vendor/start
lee@ubuntu:~$ git clone https://github.com/ctrlpvim/ctrlp.vim

Customize the plugin by editing .vimrc file by studying the [document](ctrlp.vim/readme.md at master · ctrlpvim/ctrlp.vim (github.com)).

4. Redo demo in the class

def fizz_buzz(limit):
    for i in range(limit):
        if i % 3 == 0:
            print('fizz')
        if i % 5 == 0:
            print('fizz')
        if i % 3 and i % 5:
            print(i)

def main():
    fizz_buzz(10)

We will fix the following issues:

• Main is never called
• Starts at 0 instead of 1
• Prints “fizz” and “buzz” on separate lines for multiples of 15
• Prints “fizz” for multiples of 5
• Uses a hard-coded argument of 10 instead of taking a command-line argument

5. Macro

​ Convert XML to JSON (example file) using Vim macros. Try to do this on your own, but you can look at the macros section above if you get stuck.

1. GG dd and gg dd the first and the last line

2. press q and a to start recording macro

3. V select the line number 1 and r{ to replace to {

4. Jump to the line and wd<$d<0 press "name" and somthing

5. Jump to the line do things like 3

6. do things like 2

7. jump to the next line

8. Stop recording to press q
