git maildiff mail's diff in color to reviewer/ co-worker

1/26/2014

So last weekend I started digging into this finding a way how can i save my time by pushing the latest commit of my git branch and emailing the colleague i work with the colour diff, lately last weekend I also discovered that there is already a command that do part of it , git send-email I thought I could use that, but unfortunately I was disappointed that it doesn't send diffs in colour, then I found a package on pypi ansi2HTML and thought my problem is solved and to my astonishment I discovered that I cannot use git send-email in conjunction with ansi2HTML since ansi2HTML embeds styles in head tag in HTML <style > for colour formatting and gmail doesn't support <styles> tag within the message body. So I kept going, and just yesterday I came up with a way to convert simple diff to HTML colour diff, then I used smtplib python module to send email. manually tested and all working fine.

alright, started with GIT a while back, and since GIT is also how I manage my code at office, it is indispensable thing I must know. So here are few git commands I learnt so far.

if you don't want to use terminal for git command you can use sourceTree or magit on emacs

git init # initializes the git repository
git add <filename> # add files git repository
git commit -m "message here what you did or what you added"
git remote show origin # shows remote branches
git config --get remote.origin.url # will show remote repo url

git status # displays the status of what you did in past with the repository with dates and message you typed in while making a commit
git branch <name of the branch here> # this will create a branch of the master you can work on , at office I am supposed to work on my branch not permitted to master.
git log --oneline --pretty=format:"%H" will output all the commit SHA ID
git rev-parse origin/master # will output latest commit id of remote/origin, provided you run git fetch before.
git config --get remote.origin.url # will output the repository remote URL
git ls-remote {url} refs/heads/{branch} | awk '{print $1}' # will output the latest commit SHA ID of the given branch
git rev-parse master # will output latest commit ID locally
git checkout master # this will checkout if you are in branch to master, or if you are in master then you type this
git pull origin <branchName> # pulls updated code from github or remote
git checkout mybranch # so now I will checkout from mybranch to master
for what I learnt at home, since I use github.com, here is how I will put the files to github using ssh but before that few things to do.
git remote set-url pySan https://github.com/<username here>/pySan.git
sets url for remote repository

git remote prune origin
Deleting the refs to the branches that don't exist on the remote clean local repositories

git remote -v # to list url already set on local repository
git remote set-url origin https://sanfx@github.com/sanfx/pySan.git
# this will set url for my github repository to put code on github.com

git push origin :<branchName>
# will delete the git branch from remote
git pull origin <branchName> # to pull specific branch from remote
git push -f origin <branch name> # any branch name you specified that you want to put to server on github.com or <branch name> could be master if you are going to put update the master .
git push -u origin <newBranchName> # this creates a remote branch if it doesn't exist)
git diff branchNameCompareTo branchName -- file_to_diff.ext
# to compare files from two different branches and this one i learnt today from stackoverflow
git for-each-ref --sort=-committerdate refs/heads/ --format='%(committerdate:short) %(authorname) %(refname:short)' # this will list all the local branch in a sorted order and jusified
git for-each-ref --sort=-committerdate refs/heads/ # will print the commit ssh keys
git ls-remote --heads origin # this will list all the remote branch commits
git branch -m <oldBranchName> <newBranchName> # rename a git branch
git pull
then to get the branch
git checkout -b <branchName> origin/<branchName>
<branchName> is the one that is pushed and you are trying to pull it on different location
git push all <branchName>
to push to multiple repositories
git rerere -- The git rerere functionality is a bit of a hidden feature. The name stands for "reuse recorded resolution" and as the name implies, it allows you to ask Git to remember how you've resolved a hunk conflict so that the next time it sees the same conflict, Git can automatically resolve it for you. To enable the rerere functionality, you simply have to run this config setting:
$ git config --global rerere.enabled true
git reset --hard HEAD~1
undo last merge/ commit
