How To Git

NeXT Steps

 here everything has yet to be done !

coming soon :

Everything You Always Wanted to Know on git [seldom]... (But Were Afraid to Ask) a collection of links of interest

useful commands

gitk
gitk --all

git apply

git apply path-to-apatch-file

see option --check and --stat

git-init

git init

git-clone

git clone git://github.com/foo/bar.git

git clone --recurse  git://github.com/foo/bar.git
git clone --recurse -j8 git://github.com/foo/bar.git
git clone --recurse-submodules git://github.com/foo/bar.git
git clone --recurse-submodules -j8 git://github.com/foo/bar.git

git-config

# git attitude git config (french)
git config --list
git config --list --show-origin

git config --global user.name "Your Name Comes Here"
git config --global user.email you@yourdomain.example.com

core.whitespace true
core.autocrlf true
core.safecrlf true
core.eol

core.symlinks false

core.whitespace true

   A comma separated list of common whitespace problems to notice. 
   git diff will use color.diff.whitespace to highlight them, and git apply --whitespace=error will consider them as errors. 
   You can prefix - to disable any of them (e.g. -trailing-space):

   blank-at-eol 
   treats trailing whitespaces at the end of the line as an error (enabled by default).

   space-before-tab 
   treats a space character that appears immediately before a tab character in the initial indent part of the line as an error (enabled by default).

   indent-with-non-tab 
   treats a line that is indented with space characters instead of the equivalent tabs as an error (not enabled by default).

   tab-in-indent 
   treats a tab character in the initial indent part of the line as an error (not enabled by default).

   blank-at-eof 
   treats blank lines added at the end of file as an error (enabled by default).

   trailing-space
   is a short-hand to cover both blank-at-eol and blank-at-eof.

   cr-at-eol 
   treats a carriage-return at the end of line as part of the line terminator, i.e. with it, trailing-space does not trigger 
   if the character before such a carriage-return is not a    whitespace (not enabled by default).

   tabwidth=<n> tells how many character positions a tab occupies; this is relevant for indent-with-non-tab and when Git fixes tab-in-indent errors. 
   The default tab width is 8. 
   Allowed values are 1 to 63.

# TextMate : l'invocation en ligne de commande mate doit être installée (ça se fait depuis Help > Terminal Usage… dans la v1 et depuis l'onglet Terminal des Préférences dans la v2), après quoi c'est juste mate -w.
#SublimeText : il faut avoir un appel en ligne de commande, là aussi. Sur OSX avec ST2, j'ai un lien symbolique /usr/local/bin/subl vers /Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl, qui est fourni pour ça. Après quoi subl -w.
#GEdit : gedit -w -s
#GVim : gvim --nofork
#Coda : Il vous faut installer coda-cli (généralement via Homebrew, toujours aussi utile…) après quoi coda -w.
#Chocolat : Installez l'appel en ligne de commande (Chocolat > Install Command Line Tool…) après quoi choc -w
#Notepad++ : vous aurez peut-être besoin d'adapter le chemin en fonction de là où vous avez installé Notepad++, mais voici l'idée : 'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin.
#Ultra-Edit : uedit32 /fni
# on macOS , depending on applications, you may have to go inside the application package

git merge

resolving conflict with binary files

If you want to take your changes over the ones you’re merging in, simply run:

   git checkout --ours -- path/to/file.binary
   git add path/to/file.binary
 or
   git add somefile.dll 
   git commit –m “My commit message for the merge”

Inversely, if you want to take the merging changes over your own you can run

   git checkout --theirs -- path/to/file.binary
   git add path/to/file.binary
 or
   git checkout otherbranch somefile.dll

This works on non-binary files, too, but keep in mind it’s all-or-nothing. Either use all your changes to a file, or all theirs.

How-To

clean a git repository
- https://git-scm.com/book/fr/v2/Utilitaires-Git-Remisage-et-nettoyage

how to get a file history

 git log -- <filePath>
 git log <filepath>

using reflog and git reset to cancel actions

resetting

cancelling the last pushed commit

 git revert

- https://makina-corpus.com/blog/metier/archives/git-annuler-proprement-un-commit-apres-un-push

cancelling the last commit (not yet pushed)

 git reset HEAD~

resetting a local branch after the remote branch on the server

 git reset --hard origin/<myRemoteBranch>

This removes everything from the index, then just run:

 git rm -r --cached .

removing a file or a folder committed by mistake , and without deleting it from local file system
- https://stackoverflow.com/questions/1143796/remove-a-file-from-a-git-repository-without-deleting-it-from-the-local-filesyste

git rm -r --cached File-or-FolderName
git commit -m "Removed folder from repository"

Applying a .gitignore file added well after having committed file

 git rm -r --cached .
 git add .
 git commit -m ".gitignore is now working"

patches
- create a patch

 git diff >> patch file

** accept a patch
