عارض JSON في Bash — jless & JQ_COLORS

# macOS
brew install jless

# Linux — prebuilt binary from GitHub Releases
curl -sL https://github.com/PaulJuliusMartinez/jless/releases/latest/download/jless-x86_64-unknown-linux-gnu.tar.gz \
  | tar xz
sudo mv jless /usr/local/bin/

# Verify
jless --version

# Open a local file — interactive tree viewer launches immediately
jless api-response.json

# Pipe any JSON stream directly into jless
curl -s https://api.github.com/users/torvalds | jless

# Open with all nodes collapsed to top level (useful starting point for large documents)
jless --mode line api-response.json

# Load a specific array element and view it in isolation
jq '.[0]' deployments.json | jless

# Inside jless:
#
#   j / ↓        move down
#   k / ↑        move up
#   l / →        expand node (or Enter)
#   h / ←        collapse node
#   H            collapse current + all siblings → high-level overview
#   L            expand everything recursively
#
#   /            start forward search — type a key name and press Enter
#   n / N        next / previous search match
#
#   g / gg       jump to start
#   G            jump to end
#   q            quit

# Basic colorized pager
jq -C . response.json | less -R

# From a curl response — -s prevents progress bar from corrupting the JSON stream
curl -s https://api.github.com/repos/jqlang/jq | jq -C . | less -R

# Sort keys for easier visual scanning, then page
jq -CS . config.json | less -R
# -C = force color, -S = sort keys (both flags combined)

# Add an alias so you never have to type the full pipe again
alias jqv='jq -C . | less -R'
# Usage: cat response.json | jqv
#    or: curl -s https://api.example.com/status | jqv

# ANSI color reference for building JQ_COLORS:
#   Attributes:  0=normal  1=bold  2=dim  4=underline
#   Colors:      30=black  31=red  32=green  33=yellow
#                34=blue   35=magenta  36=cyan  37=white
#   Bright:      90=bright-black  91=bright-red  92=bright-green  93=bright-yellow
#                94=bright-blue  95=bright-magenta  96=bright-cyan  97=bright-white
#
# Order: null : false : true : numbers : strings : arrays : objects

# High-contrast theme for dark terminals (recommended)
export JQ_COLORS="1;30:0;91:0;92:0;93:0;32:1;96:1;96"
# null=dim-gray, false=bright-red, true=bright-green,
# numbers=bright-yellow, strings=green, arrays=bold-cyan, objects=bold-cyan

# Solarized-style theme
export JQ_COLORS="2;37:0;35:0;35:0;36:0;33:1;34:1;34"
# null=dim-white, false=magenta, true=magenta,
# numbers=cyan, strings=yellow, arrays=bold-blue, objects=bold-blue

# Minimal (bold keys only, everything else plain)
export JQ_COLORS="0;90:0;39:0;39:0;39:0;39:1;39:1;39"

# Add your chosen theme to ~/.bashrc or ~/.zshrc so it applies to every jq call
echo 'export JQ_COLORS="1;30:0;91:0;92:0;93:0;32:1;96:1;96"' >> ~/.bashrc
source ~/.bashrc

# Test the theme
echo '{"active":true,"errors":null,"count":42,"tags":["api","v2"],"meta":{"version":"1.0"}}' | jq .

# Add to ~/.bashrc or ~/.zshrc

# jv — interactive viewer (jless if available, colorized pager fallback)
jv() {
  if command -v jless &>/dev/null; then
    jless "$@"
  else
    jq -C . "$@" | less -R
  fi
}

# jvp — view with keys sorted alphabetically (useful for comparing responses)
alias jvp='jq -CS . | less -R'

# jvc — view from clipboard (macOS)
alias jvc='pbpaste | jless'

# jvf — view and filter: jvf '.users[0]' response.json
jvf() {
  local filter="$1"; shift
  jq -C "$filter" "$@" | less -R
}

# Reload without restarting terminal
source ~/.bashrc

# Usage examples after adding aliases above

# View any file or piped response
jv deployment-config.json
curl -s https://api.github.com/users/torvalds | jv

# View sorted (easy to scan alphabetically)
cat feature-flags.json | jvp

# Drill into a sub-document interactively
jvf '.database' infra/app-config.json
jvf '.users[] | select(.role == "admin")' users.json

# macOS
brew install bat

# Debian / Ubuntu (binary may be named batcat)
apt-get install -y bat
# alias bat=batcat   # add to ~/.bashrc if needed on Ubuntu

# View a JSON file with syntax highlighting and line numbers
bat config/feature-flags.json

# Disable pager — print directly to terminal (useful in scripts)
bat --paging=never api-response.json

# Combine with jq: format with jq, view with bat (preserves bat's JSON highlighting)
jq '.' response.json | bat --language=json --paging=never

# Install globally via npm
npm install -g fx

# Or run without installing (npx caches the package)
curl -s https://api.github.com/users/torvalds | npx fx

# Basic interactive use
fx api-response.json
curl -s https://api.github.com/repos/jqlang/jq | fx

# In fx: arrow keys navigate, Enter expands/collapses, / searches
# Bottom bar accepts JavaScript expressions for live filtering:
#   .name           → show only the "name" field
#   .repos.slice(0,5) → first 5 repos

# fx also works as a non-interactive formatter (like jq . but with JS syntax)
# Pass a JavaScript expression as argument — no interactive mode
echo '{"users":[{"id":1,"name":"Sarah Chen"},{"id":2,"name":"Marcus Osei"}]}' \
  | fx '.users[0].name'
# Sarah Chen

# Chain with map for array transformations
cat deployments.json | fx '.items.map(d => ({id: d.deploy_id, status: d.state}))'
