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

How-To

• 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

• 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 .

• 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
 git format-patch patch-file

** accept a patch
 git apply patch_file
