HISTSIZE=10240
# The number of lines of history will be saved

# All running zsh sessions will have exactly the same history
# Don't worry - '!' command and so will work only with current session's history

# PROMPT
#

# Load and initialize colors - we will use it soon
autoload colors && colors
# Prompt on the left is % if regular user or # if root
PROMPT="%{$fg[green]%}%# %{$reset_color%}"
# if connected via ssh, make prompt red
[[ -n ${SSH_CONNECTION} ]] && PROMPT="%{$fg[red]%}%# %{$reset_color%}"
# Prompt on the right is current directory (green font)
RPROMPT="%{$fg[green]%}%~%{$reset_color%}"

#
# ALIASES
#
# NOTE: if you don't want an alias to be used (for example, you went just 'du',
# but alias is 'du -h') you have two ways:
# - use full path to binaries (continuing example above, it will look like 
#   '/bin/du')
# - use 'noglob' before command name (e.g., 'noglob du')

# Regular aliases
alias ls="ls -lF --color"
alias l="ls"
alias sl="ls"
alias lsa="ls -a"
alias bzip2='bzip2 -vv --best'
alias bunzip2='bunzip2 -vv'
alias gzip='gzip --best -v'
alias gunzip='gunzip -v'
alias less='less -R'
alias feh='feh -F'
# Some nocorrect aliases (needed only if CORRECT is set)
alias df='nocorrect df -h'
alias du='nocorrect du -h'
alias mv='nocorrect mv -i'
alias cp='nocorrect cp -i'
alias rm='nocorrect rm -i'
alias vim='nocorrect vim'
alias mc='nocorrect mc'
alias mkdir='nocorrect mkdir -p'
# You need run-help module to be loaded to have 'run-help' command
# See MISCELLANEOUS section below
alias help="run-help"

# Some more complicated but still useful aliases
# Start x; works only if user aren't root and command given from tty
#alias x='if [[ $UID != 0 && $TERM == "linux" ]]; then rm -f ~/.xsession-errors; startx; else echo "You are not allowed to start X session"; fi'

if [ "$TERM" = "linux" ]; then
    alias mplayer='mplayer -vo fbdev2'
fi

# Suffix aliases for easier files processing
# PDF
alias -s pdf=evince

# FB 2.1

alias -s fb2.bz2=fbless

# DejaVu
alias -s djvu=evince
