Another Attempt at Wag3

Until now we had done as of following code. We would create couples of more functions which would help us in managing our application. As discussed earlier we would now we creating different directories and files present inside .git directory along with directory itself. More or less we would something like following directory structure after doing wag init

.git is the git directory itself, which contains:
- .git/objects/ : the object store, which we’ll introduce in the next section.
- .git/refs/ the reference store, which we’ll discuss . It contains two subdirectories, heads and tags.
- .git/HEAD, a reference to the current HEAD (more on that later!)
- .git/config, the repository’s configuration file.
- .git/description, the repository’s description file.

import sys
import argparse
import os

argparser = argparse.ArgumentParser(description="Another Content Tracker")
argsubparsers = argparser.add_subparsers(title="Commands", dest="command")
argsubparsers.required = True
argsp = argsubparsers.add_parser(
 "init", help="Initialize a new, empty repository.")
argsp.add_argument("path", metavar="directory", nargs="?",
 default=".", help="Where to create the repository.")


def main(argv=sys.argv[1:]):
 args = argparser.parse_args(argv)
 if args.command == "init":
 cmd_init(args)


def cmd_init(args):
 repo_create(args.path)


class GitRepository(object):
 """A git repository"""
 worktree = None
 gitdir = None

 def __init__(self, path, force=False):
 self.worktree = path
 self.gitdir = os.path.join(path, ".git")


def repo_create(path):
 """Create a new repository at path."""
 repo = GitRepository(path)
 # We check whether there exsits a path of worktree
 if os.path.exists(repo.worktree):
 # if path exsits its a directory or not
 if not os.path.isdir(repo.worktree):
 raise Exception("%s is not a directory!" % path)
 # if path exsits its empty or not
 if os.listdir(repo.worktree):
 raise Exception("%s is not empty!" % path)
 else:
 # Create directory as nothing exist with same path
 os.makedirs(repo.worktree)

Now let’s create function which would gives us path of directory after verifying that the directory exist and if it doesn’t it should gives us an error. We would also require mechanism to check whether we need to create the directory or not if it doesn’t exists.

Last time we had created cmd_init(args) function. We add more functionality to cmd_init(args).

This was our code till last time.

 args = argparser.parse_args(argv)
 if args.command == "init":
 cmd_init(args)
 

def cmd_init(args):
 print("Hello from init")
 

We had added an argument to your sub parser called path. If the value of path is not specified it would be ‘.’ current directory or it would whatever specified. This would help us

Another Attempt to write a git

Second Try

We would be trying to create a mini git clone from this tutorial. I aspect this to go long. In general git is awesome source code manager which is wieldy use.

So first we would be creating a lib file and executing file.

Let’s create a file called wag which would have following code.

1
2
3
4


#!/usr/bin/env python3

import libwag
libwag.main()

Then we would create another file which would be libwag.py with just a main function in it.

Day 4

PS: These are notes, there could be grammar error and spelling errors.

for loops

For loop over a list goes as follows:

1
2
3
4
5
6
7
8


>>> a = ['Fedora', 'is', 'powerful']
>>> for x in a:
... print(x)
...
# these ... are automatically created by python interpreter
Fedora
is
powerful

range() function

range function creates lists based on parameter passed in function``py

1
2
3
4
5
6


>>> list(range(1, 5)) # when two numbers are passed n,j List starts at n ends at j-1
 [1, 2, 3, 4]
>>> list(range(1, 15, 3)) # when three numbers are passed n,j,k. List starts at n ends at j after stepping at every k steps
[1, 4, 7, 10, 13]
>>> list(range(10)) # when only single number n is passed list starts from 0 and ends after n elements
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Continue statement

Just like break is use to break loop, continue is used to continue loop towards iteration without further execution A combined example.

Day 3

PS: These are notes, there could be grammar error and spelling errors.

Last time we were just starting with If else, the control flow,

if-else , the control flow

Control flow is used when we need to do some decisive task

if, if else, if elif else statement

If statement is simple as it is other language

if expression:
 do this

1

4


if expression:
 do this
else:
 do this

if expression:

elif expression:

else:

Day 2

PS: These are notes, there could be grammar error and spelling errors.

Last time had got until here,

We don’t need specify data type with python something similar to javascript where we use var for every type of variable.(const and let are new ES6 standards, although they are not new but new)

So basically

1
2
3


a = 10
b = 1.0
c = "test"

in above a become integer, b becomes float and c becomes string.

Day 1

Installing python

one can install python using package manager depending upon the operating system you are using. As I have a windows machine and ubuntu using linux on windows subsystem. I can install python from https://python.org . And Ubuntu I can use below command to install python.

`1`	`sudo apt-get install python3`

Running python

To run python you would call python3 which open Python interpreter. On that you can type print(“Hello World”) to run your first python code which would print Hello World in next line.

So Last year in some Facebook group or somewhere I read about summer training offered by dgplug on IRC chat. I had heard about IRC chat before and had tried to use it once or twice but never tried to use it or understand it.

Technically summer trainings are usually for college students but during my college time I was too busy being in and around Microsoft Student Partner that I didn’t knew about many things around. More about dgplug – Linux User’s Group of Durgapur. An inside how awesome is internet, if you want to travel to Durgapur from Gandhidham(my place) it is 2160 km. This is year training started on 17 Jun and today its already 17 July, I am always late :-D.
