Statusline

Statusline Implementation

Complete reference for building Claude Code status line scripts with themes, modules, and helpers.

Themes

Five built-in themes with consistent indicator mappings:

Theme: default

Standard emoji theme - works in all modern terminals.

Helper Functions

get_status (3-level)

Returns status indicator based on percentage threshold.

get_status() {
  local pct=$1
  local warn_threshold=${2:-50}
  local crit_threshold=${3:-75}

  if (( pct >= crit_threshold )); then
    echo "$STATUS_CRIT"
  elif (( pct >= warn_threshold )); then
    echo "$STATUS_WARN"
  else
    echo "$STATUS_OK"
  fi
}

get_status_4level (4-level)

Returns status indicator with fair level (for rate limits).

get_status_4level() {
  local pct=$1
  local fair_threshold=${2:-25}
  local warn_threshold=${3:-50}
  local crit_threshold=${4:-75}

  if (( pct >= crit_threshold )); then
    echo "$STATUS_4_CRIT"
  elif (( pct >= warn_threshold )); then
    echo "$STATUS_4_WARN"
  elif (( pct >= fair_threshold )); then
    echo "$STATUS_4_FAIR"
  else
    echo "$STATUS_4_OK"
  fi
}

progress_bar

Creates visual progress bar.

progress_bar() {
  local pct=$1
  local width=${2:-10}
  local filled=$(( pct * width / 100 ))
  local empty=$(( width - filled ))

  printf "["
  printf "%${filled}s" | tr ' ' '='
  printf "%${empty}s" | tr ' ' '-'
  printf "]"
}

safe_int

Safely converts value to integer.

safe_int() {
  local val="$1"
  local default="${2:-0}"

  # Remove decimal portion and non-numeric chars
  val="${val%%.*}"
  val="${val//[^0-9-]/}"

  if [[ "$val" =~ ^-?[0-9]+$ ]]; then
    echo "$val"
  else
    echo "$default"
  fi
}

json_get

Safe JSON extraction (handles missing jq gracefully).

json_get() {
  local json="$1"
  local path="$2"
  local default="${3:-}"

  if command -v jq &>/dev/null; then
    local result

File Operations (REQUIRED)

After generating the statusline script, you MUST complete these steps:

1. Determine config directory:

   CLAUDE_CONFIG="${CLAUDE_CONFIG_DIR:-$HOME/.claude}"
   

2. Backup existing statusline (if present):

   if [ -f "$CLAUDE_CONFIG/statusline.sh" ]; then
       BACKUP_TS=$(date +%Y%m%d-%H%M%S)
       cp "$CLAUDE_CONFIG/statusline.sh" "$CLAUDE_CONFIG/statusline.sh.bluera-base-backup-$BACKUP_TS"
   fi
   

3. Write the script to the config directory:

   cat > "$CLAUDE_CONFIG/statusline.sh" << 'STATUSLINE_EOF'
   <generated script content here>
   STATUSLINE_EOF
   

4. Make executable:

   chmod +x "$CLAUDE_CONFIG/statusline.sh"
   

5. Verify the file exists and is executable:

   ls -la "$CLAUDE_CONFIG/statusline.sh"
   

The statusline will not work until these steps are completed.

Preserving User Customizations

When modifying an existing $CLAUDE_CONFIG/statusline.sh, preserve user-added content:

Detection Patterns

Look for these indicators of custom code:

1. Boundary comments:

   • # --- custom --- / # --- end custom ---
   • # --- user --- / # --- end user ---
   • # --- <name> status --- / # --- end <name> status ---

2. Custom function definitions:

   • Functions not matching standard module names
   • Example: get_cca_status(), get_k8s_status()

3. External service integration:

   • curl to localhost/127.0.0.1 addresses
   • Reads from non-standard config files
   • Environment-specific ports or paths

4. Custom variables in output:

   • Variables referenced in final echo/printf that aren't from standard modules

Preservation Algorithm

1. Read existing script
2. Extract sections between boundary comments
3. Identify custom variables used in output format
4. Generate new script with standard modules
5. Append preserved custom sections before output
6. Update output format to include custom variables

Example: CCA Integration (Preserve)

# --- claude-code-anywhere status ---
CCA_STATUS=""
_CCA_PORT=$(cat ~/.config/claude-code-anywhere/port 2>/dev/null)
if [ -n "$_CCA_PORT" ]; then
    _CCA_RESP=$(curl -s --max-time 1 "http://127.0.0.1:${_CCA_PORT}/health" 2>/dev/null)
    if [ -n "$_CCA_RESP" ]; then
        CCA_STATUS="${SEP}${ICON_CCA}CCA${STATUS_OK}"
    fi
fi
# --- end claude-code-anywhere status ---

This should be preserved because:

• Has clear boundary comments
• Fetches from local service (127.0.0.1)
• Defines CCA_STATUS variable used in output

Preset: bluera

Advanced statusline with rate limits, context bar, and ANSI colors.

Features:

• ANSI terminal colors (not emojis for status)
• 10-character context progress bar (█░)
• Rate limits (5h/7d) from Anthropic API with caching
• Lines changed (+/-) in session
• Project type detection (🦀🐹🐍💧💎📦🦕▲⚡🍞)

Output format:

Model dir project branch │ $cost │ [ctx bar] pct% │ +added/-removed │ 5h:X% 7d:Y%

Example:

Opus 4.5 myproject 🐍 main* │ $1.23 │ ██████░░░░ 60% │ +42/-8 │ 5h:12% 7d:8%
