# notes
##########

# this script creates repos in a sandbox directory and uses them for demos.
# add an exit command anywhere to stop the script and examine repo state.
# rerun the script freely. it cleans up the sandbox before each run.
# the sandbox dir is ignored so created files are not added to any uber repo.

# terminology

	# working, staged, committed <=> filesystem, index, commit graph
	# ref => a branch ref or a tag ref

# direction of git diff

	# "git diff commitA commitB", where commitA predates commitB, 
	# will show the changes required to transform commitA into commitB.
	# similarly, when diffing within a single commit 
	# (e.g., diff staged and committed),
	# git shows the changes needed to transform older state into newer state.
	# in this case, committed is "older", 
	# so git diff shows how to transform committed into staged.
	
# examining repo state

	# suggest to set the git la alias described below and run it often.
	# it's an easy way to visualize HEAD, branches, tags, and the commit graph.

# two ways to create a local repo and associate remote:
# 1) init locally and add remote manually. (commented out)
# 2) clone remote. (uncommented) 
	# this 2nd approach copies down any repo content if it exists.

# in most workflows, a coder will pull code from an upstream repo,
# edit it, and push it back to the upstream repo, possibly in a new branch.

	# the default remote is used for fetch and push commands run without args.
	
	# it is possible to configure a remote to use different fetch and push urls.
	# this means we could configure a branch to have a default remote which
	# pulls from one repo and pushes to another repo.
	# however, this breaks the convention that a remote represents one "repo".
	# also, the convention used by github is to define a separate remote
	# for each push or pull location.

# "*" vs "." vs "-A"

	# "git add *" is intercepted by the shell and 
	# git gets a list of files in the current dir.
	# the list will not include files that begin with ".".

	# "git add ." is not intercepted by the shell, 
	# and git will interpret it to mean all files in the current dir and down.
	# https://stackoverflow.com/q/26042390/2512141

	# "git add -A" adds all changes from repo root down, 
	# regardless of where it is called.
	
# "origin/master" vs "origin master"

	# roughly, "origin/master" is a branch ref which refers to a
	# local copy of a remote branch and is used in local operations,
	# while "origin master" is used in commands that 
	# actually change the remote repo.

# git checkout vs git reset

	# git checkout moves only HEAD, and copies contents 
	# of addressed commit to staged and working.
	# git reset moves HEAD and HEAD's tag, then copies to staged 
	# and working, depending on flags.
	# git reset can alter pushed history (use caution).
	# https://stackoverflow.com/q/3639342/2512141

# .gitignore syntax
	
	# a "/" at the beginning or middle of an ignore pattern means the pattern
	# will use the location of the .gitignore file as root.
	
	# patterns without a "/" at the beginning or middle apply everywhere.
	
	# patterns with "/" at the beginning or middle can be made to apply anywhere
	# by preceding with "**".
	
	# it is possible to use multiple .gitignore files in a repo.

	# *.txt
		# ignore all files and directories that end with ".txt".
	# foo
		# ignore all files and directories named "foo".
	# foo/
		# ignore all directories named "foo".
	# /foo
		# ignore file or directory named "foo" in repo root.
