#-------------------------------------------------------------
#
# When changing directory small typos can be ignored by bash
# for example, cd /vr/lgo/apaache would find /var/log/apache
# shopt -s cdspell
#
# Check that a command found in the hash table exists before trying to execute it. If it doesnt, a normal path search is performed.
shopt -s checkhash
#
# Warn if there are running/stopped jobs when attempting to exit Bash
# shopt -s checkjobs
#
# Attempt to save all lines of a multi-line command in the same history entry. Normally on by default.
shopt -s cmdhist
#
# For any 'foo.exe' during completion, if 'foo' and 'foo.exe' are the same file, strip the '.exe' suffix
[ "$OSTYPE" == 'msys' ] && shopt -s completion_strip_exe
#
# Include filenames beginning with '.' in the results of filename expansion.
# shopt -s dotglob
#
# Expand aliases even while in a non-interactive shell
# shopt -s expand_aliases
#
# Make bash append rather than overwrite the history on disk
shopt -s histappend
#
# Don't automatically execute history expansions; expand them on a new line for review first
shopt -s histverify
#
# Don't use ^D to exit on the first try
# set -o ignoreeof
#
# Use case-insensitive filename globbing
# shopt -s nocaseglob
#
# Make the ** glob pattern match all files, in addition to the default behavior of matching any directories and subdirectories.
# shopt -s globstar
#
# Make glob patterns with no matches expand to an empty string, rather than to themselves.
# shopt -s nullglob
#
# Make glob patterns with no matches (after filename expansion) result in an expansion error.
# shopt -s failglob
#
# Disable completion when the input buffer is empty.  i.e. Hitting tab
# and waiting a long time for bash to expand all of $PATH.
shopt -s no_empty_cmd_completion
#
# Don't wait for job termination notification
# set -o notify
#
# Use the TARGET of symbolic links when performing commands such as 'cd' which change the current directory
# set -o physical
#
# Aliases can use the programmable completion for the command they alias
shopt -s progcomp_alias >/dev/null 2>&1
#
# If this is set, the shift builtin prints an error message when the shift count exceeds the number of positional parameters.
# shopt -s shift_verbose
#
# Don't search through $PATH for files when using the builtin 'source' command
shopt -u sourcepath

# Completion options
#-------------------------------------------------------------
# These completion tuning parameters change the default behavior of bash_completion:
#
# Define to access remotely checked-out files over passwordless ssh for CVS
# COMP_CVS_REMOTE=1
#
# Define to avoid stripping description in --option=description of './configure --help'
# COMP_CONFIGURE_HINTS=1
#
# Define to avoid flattening internal contents of tar files
# COMP_TAR_INTERNAL_PATHS=1
#
# Uncomment to turn on programmable completion enhancements.
# Any completions you add in your ~/.bash_completion file are sourced last.
# [ -r /etc/bash_completion ] && . /etc/bash_completion
# MAY CAUSE NOTICABLE IMPACT ON SPEED OF LOADING BASH
#
# This should only attempt to source completions if the file exists AND the completions have not already been sourced by the shell.
# [ -r /etc/bash_completion -a "x${BASH_VERSION-}" != x -a "x${PS1-}" != x -a "x${BASH_COMPLETION_VERSINFO-}" = x ] && . /etc/bash_completion

# History Options
#-------------------------------------------------------------
# Don't put duplicate lines in the history.
# export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
# export HISTCONTROL=ignorespace:ignoredups		#subsumed by `[ \t]*:&` in HISTIGNORE
#
# Ignore some controlling instructions
# HISTIGNORE is a colon-delimited list of patterns which should be excluded. Honors the setting of the extglob shell option.
# The '&' is a special pattern which suppresses duplicate entries.
# export HISTIGNORE=$'[ \t]*:&:[fb]g:exit'
# export HISTIGNORE=$'[ \t]*:&:[fb]g:exit:ls:which:pwd:clear:cls' # Ignore some other commands as well.
#
HISTIGNORE=$'[ \t]*:&:[fb]g:j:jobs:exit:clear:cls:history:history -a'

# Enable this for unlimited history file length.
# export HISTFILESIZE=-1

# I want to store command history forever, but having to parse really long history files can slow down bash.
# To avoid that issue, when the history file exceeds 450 lines, dump the contents of the history file into another file that bash wont parse on load.
# Then, truncate the history file.
