# /DATA/.bashrc for interactive shell configuration in Bash
# This file customizes your Bash shell environment in ZimaOS with a Solarized-inspired look and handy tools.
# Note: In ZimaOS, this might be in /DATA/.bashrc instead of ~/.bashrc due to system configuration.

# Source global definitions (if they exist)
# Loads system-wide Bash settings if /etc/bashrc exists.
if [ -f /etc/bashrc ]; then
    . /etc/bashrc  # '.' is shorthand for 'source'.

# PATH
##############################################################

# Defines where Bash looks for commands, adding personal and system directories.
export PATH=$PATH:~/bin:/usr/bin:/bin:/usr/sbin:/sbin
# - ~/bin: Personal scripts/binaries.
# - /usr/bin, /bin: User and system commands.
# - /usr/sbin, /sbin: Admin commands (some need sudo).

# PROMPT (Solarized-inspired with tput)
##############################################################

# Colors using tput for a Solarized-inspired prompt.
BASE1=$(tput setaf 247)   # Light gray (#93a1a1) for user@host, visible on dark terminals.
BASE0=$(tput setaf 244)   # Light gray (#839496) for directory.
YELLOW=$(tput setaf 136)  # Yellow (#b58900) for prompt symbol and accents.
GREEN=$(tput setaf 100)   # Green (#859900) for success indicator.
RED=$(tput setaf 124)     # Red (#dc322f) for error indicator.
RESET=$(tput sgr0)        # Resets color to default.

# Dynamic prompt: Shows green ➜ if last command succeeded, red if it failed.
PS1='\[$BASE1\]\u@\h\[$RESET\]:\[$BASE0\]\w\[$RESET\] $(if [ $? -eq 0 ]; then echo "\[$GREEN\]➜"; else echo "\[$RED\]➜"; fi) \[$YELLOW\]\$\[$RESET\] '
# - \u@\h: Username@hostname.
# - \w: Current directory.
# - $(if [ $? -eq 0 ]...): Checks last command’s exit status ($?), green ➜ for success (0), red for failure.
# - \$: '$' for user, '#' for root.

# COLOR SUPPORT (using dircolors)
##############################################################

# Sets up colored ls output with dircolors.
eval "$(dircolors -b)"    # Loads default color database.

# Tip: To customize colors further, edit ~/.dircolors (if writable) with Solarized values.

##############################################################
# HISTORY SETTINGS
##############################################################

# Configures command history.
HISTSIZE=1000             # Max commands in memory: 1000.
HISTFILESIZE=2000         # Max commands in ~/.bash_history: 2000.
HISTCONTROL=ignoreboth    # Ignores duplicates and space-prefixed commands.
shopt -s histappend       # Appends to history file instead of overwriting.

##############################################################
# COMPLETION
##############################################################

# Enables tab completion if system-wide completion script exists.
if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion  # Loads completion rules.
