TermStack YAML Configuration Generator

This skill helps generate TermStack YAML configuration files for creating terminal user interfaces (TUIs) that browse APIs, display data in tables, stream logs, and navigate between pages.

What is TermStack?

TermStack is a config-driven Terminal User Interface (TUI) framework. You define pages, data sources, views, and actions in YAML - no coding required. It supports:

• HTTP API calls with query parameters and headers
• CLI command execution with arguments
• Script execution for custom data processing
• Stream adapters for real-time data (logs, websocket)
• Table views with sortable, styled columns
• Text/YAML views for detailed data
• Logs views with filtering and search
• Multi-page navigation with context passing
• Conditional navigation based on data values
• Actions triggered by keyboard shortcuts
• Multiple data sources with merge capabilities
• Column transforms with Tera templates
• Validation rules for data integrity

YAML Configuration Structure

version: v1

app:
  name: "App Name"
  description: "App description"
  theme: "default"

globals:
  api_base: "https://api.example.com"
  # Variables accessible in all templates as {{ variable_name }}

start: page_name  # First page to show

pages:
  page_name:
    title: "Page Title"
    data:
      adapter: http  # or "cli", "script", "stream"
      url: "{{ api_base }}/endpoint"
      method: GET
      params:
        key: "value"
      headers:
        Accept: "application/json"
      items: "$.data[*]"  # JSONPath to extract array items
    view:
      type: table  # or "text", "logs"
      columns:
        - path: "$.field"
          display: "Column Name"
          width: 20
          style:
            - default: true
              color: cyan
    next:
      page: detail_page
      context:
        item_id: "$.id"
    actions:
      - key: "ctrl+d"
        name: "Details"
        page: "detail_page"
        context:
          item_id: "$.id"

Key Concepts

1. Data Adapters

IMPORTANT: Choosing the Right Field

• Use adapter: cli|http|script for single-fetch or periodic refresh data sources
• Use type: stream for real-time streaming data sources (continuous output)

HTTP Adapter

data:
  adapter: http
  url: "{{ api_base }}/users"
  method: GET  # GET, POST, PUT, DELETE, PATCH
  params:
    limit: 10
    status: "active"
  headers:
    Authorization: "Bearer {{ token }}"
    Accept: "application/json"
  items: "$.data[*]"  # JSONPath for array extraction
  timeout: "30s"  # Supports: s, m, h (e.g., "5m", "1h")
  refresh_interval: "5m"  # Auto-refresh data

CLI Adapter

data:
  adapter: cli
  command: "kubectl"
  args: ["get", "pods", "-n", "{{ namespace }}", "-o", "json"]
  items: "$.items[*]"
  timeout: "10s"
  refresh_interval: "30s"

Script Adapter

Execute external scripts for custom data processing:

data:
  adapter: script
  path: "./scripts/process_data.sh"
  args: ["--env", "{{ environment }}"]
  items: "$[*]"
  timeout: "1m"

Stream Adapter

For real-time streaming data (logs, command output):

data:
  type: stream  # Use "type" (not "adapter") for streaming
  command: "kubectl"
  args: ["logs", "-f", "pod-name", "-n", "namespace"]
  buffer_size: 1000  # Max lines to keep in buffer (default: 100)
  buffer_time: "5m"  # Time window for buffering (optional)
  follow: true  # Auto-scroll to new lines (default: true)
  timeout: "30s"  # Optional timeout

Important: Stream data sources use type: stream (not adapter: stream). The command output is streamed in real-time to the terminal.

2. View Types

Table View

Display data in columns with sorting and styling:

view:
  type: table
  columns:
    - path: "$.name"
      display: "Name"
      width: 30
      style:
        - default: true
          color: cyan
          bold: true
    - path: "$.status"
      display: "Status"
      width: 15
      style:
        - condition: "{{ value == 'active' }}"
          color: green
        - condition: "{{ value == 'inactive' }}"
          color: red
        - default: true
          color: gray
    - path: "$.created_at"
      display: "Age"
      width: 15
      transform: "{{ value | timeago }}"  # Tera filter
      style:
        - default: true
          color: yellow
    - path: "$.size"
      display: "Size"
      width: 12
      transform: "{{ value | filesizeformat }}"  # Format bytes
      style:
        - default: true
          color: blue

Text View

Display single objects as formatted text:

view:
  type: text
  syntax: yaml  # or json, xml, toml, etc.

Logs View

Display streaming logs:

view:
  type: logs
  follow: true              # Auto-scroll to new lines (default: true)
  wrap: true                # Wrap long lines (default: false)
  show_line_numbers: true   # Show line numbers (default: false)
  show_timestamps: false    # Show timestamps (default: false)

Note: Log filtering is defined in the schema but not yet fully implemented in the current version. Use the basic logs view shown above.

3. Navigation

Simple Navigation (Enter key)

next:
  page: detail_page
  context:
    item_id: "$.id"
    item_name: "$.name"

Conditional Navigation

Navigate to different pages based on data values:

next:
  - condition: "{{ row.type == 'folder' }}"
    page: folder_view
    context:
      folder_id: "$.id"
  - condition: "{{ row.type == 'file' }}"
    page: file_view
    context:
      file_id: "$.id"
  - default: true
    page: default_view

4. Actions

Actions are triggered via the Shift+A menu or direct Ctrl+key shortcuts:

actions:
  # Execute command
  - key: "ctrl+d"
    name: "Delete"
    description: "Delete this item"
    confirm: "Are you sure you want to delete {{ name }}?"
    command: "curl"
    args: ["-X", "DELETE", "{{ api_base }}/items/{{ id }}"]
    refresh: true

  # Navigate to page
  - key: "ctrl+v"
    name: "View Details"
    page: "detail_page"
    context:
      item_id: "$.id"

  # Open in external app
  - key: "ctrl+o"
    name: "Open in Browser"
    command: "open"
    args: ["{{ html_url }}"]

  # Builtin action (yaml_view is useful as a custom action)
  - key: "ctrl+y"
    name: "YAML View"
    builtin: yaml_view

5. Multiple Data Sources

Combine data from multiple sources:

data:
  sources:
    - name: users
      adapter: http
      url: "{{ api_base }}/users"
      items: "$.data[*]"
      
    - name: stats
      adapter: http
      url: "{{ api_base }}/stats"
      items: "$.data[*]"
      optional: true  # Don't fail if this source fails
      
  merge: true  # Merge all sources into single dataset

# Access in columns
view:
  type: table
  columns:
    - path: "$.name"
      display: "User"
      source: users  # From specific source
    - path: "$.count"
      display: "Stats"
      source: stats

6. Context Variables and Navigation

CRITICAL: There are TWO different syntaxes for context depending on navigation type!

A. Next Navigation (Enter key) - Uses JSONPath

# Source page - next navigation ONLY accepts JSONPath syntax
next:
  page: detail
  context:
    user_id: "$.id"              # ✅ JSONPath - extracts from selected row
    user_name: "$.attributes.name"  # ✅ JSONPath

# Target page - access as template variables
detail:
  title: "User: {{ user_name }}"  # Template variable
  data:
    url: "{{ api_base }}/users/{{ user_id }}"

B. Action Navigation (Shift+A menu / Ctrl+key) - Uses Templates

# Source page - action context ACCEPTS template expressions
actions:
  - key: "ctrl+d"
    page: detail
    context:
      user_id: "{{ id }}"                    # ✅ Template - from current row
      user_name: "{{ attributes.name }}"     # ✅ Template
      combined: "{{ namespace }}/{{ name }}"  # ✅ Template expressions work!

C. Variable Scoping and Access

Variables available in templates ({{ }}):

1. Global variables - From globals section

   globals:
     api_base: "https://api.example.com"
   # Use: {{ api_base }}
   

2. Current row fields - Flattened to top level

   # If row is: {"metadata": {"name": "pod-1"}, "status": "Running"}
   # Access: {{ metadata.name }} or {{ status }}
   

3. Previous page data - Stored by page name

   # After selecting from "namespaces" page, entire row stored as "namespaces"
   # Access: {{ namespaces.metadata.name }}
   

4. Context variables - From navigation context

   # If context passed: pod_name: "$.metadata.name"
   # Access: {{ pod_name }}
   

5. Special variables

   • {{ row }} - The entire current row object
   • {{ value }} - Current value (in transforms/conditions)
   • {{ env.VAR_NAME }} - Environment variables

Variable Resolution Priority (high to low):

1. Current row fields (flattened)
2. Page contexts (from previous navigations)
3. Global variables
4. Environment variables

D. Common Patterns

Pattern 1: Multi-level Navigation

# Page 1: namespaces
next:
  page: pods
  context:
    namespace: "$.metadata.name"  # Extract and store

# Page 2: pods (has access to {{ namespace }})
title: "Pods in {{ namespace }}"
data:
  command: "kubectl"
  args: ["get", "pods", "-n", "{{ namespace }}"]

# Navigate to logs
actions:
  - key: "ctrl+l"
    page: pod_logs
    context:
      pod_name: "{{ metadata.name }}"      # Template - from current pod
      namespace: "{{ namespace }}"         # Template - from stored context

# Page 3: pod_logs (has access to both)
title: "Logs: {{ pod_name }}"
data:
  type: stream
  command: "kubectl"
  args: ["logs", "-f", "{{ pod_name }}", "-n", "{{ namespace }}"]

Pattern 2: Accessing Previous Page Data

# Entire selected row from "users" page is stored as "users"
title: "Details - {{ users.attributes.name }}"

# OR use extracted context variable
title: "Details - {{ user_name }}"

Pattern 3: Current Row Access

# In table view, current row fields are available directly
columns:
  - path: "$.status"
    style:
      - condition: "{{ status == 'active' }}"  # Access current row's status field
        color: green

E. Key Rules Summary

Location	Syntax	Example
next.context values	JSONPath only	pod_name: "$.metadata.name"
action.context values	Templates	pod_name: "{{ metadata.name }}"
Page titles	Templates	title: "{{ namespace }}"
Data commands/URLs	Templates	args: ["-n", "{{ namespace }}"]
Transforms	Templates	transform: "{{ value | timeago }}"
Conditions	Templates	condition: "{{ value > 5 }}"

7. Styling

Available colors: black, red, green, yellow, blue, magenta, cyan, white, gray

Style modifiers: bold, dim

style:
  - condition: "{{ value > 100 }}"
    color: green
    bold: true
  - condition: "{{ value < 0 }}"
    color: red
  - default: true
    color: white

8. Column Transforms

Use Tera templates to transform column values:

columns:
  - path: "$.created_at"
    display: "Age"
    transform: "{{ value | timeago }}"  # "2 hours ago"
    
  - path: "$.bytes"
    display: "Size"
    transform: "{{ value | filesizeformat }}"  # "1.5 MB"
    
  - path: "$.status"
    display: "Status"
    transform: "{{ value | upper }}"  # ACTIVE
    
  - path: "$.price"
    display: "Price"
    transform: "${{ value | round(precision=2) }}"  # $19.99
    
  - path: "$.tags"
    display: "Tags"
    transform: "{{ value | join(sep=', ') }}"  # tag1, tag2

Available Tera filters:

• timeago - Convert timestamp to relative time
• filesizeformat - Format bytes to human-readable size
• upper, lower, capitalize - Case conversion
• round - Round numbers
• join - Join arrays
• status_color - Color code status values

9. Validation Rules

Add validation to ensure data integrity:

validation:
  rules:
    - field: "$.email"
      type: email
      message: "Invalid email format"
      
    - field: "$.age"
      type: range
      min: 0
      max: 120
      message: "Age must be between 0 and 120"
      
    - field: "$.username"
      type: regex
      pattern: "^[a-zA-Z0-9_]+$"
      message: "Username can only contain letters, numbers, and underscores"
      
    - field: "$.status"
      type: enum
      values: ["active", "inactive", "pending"]
      message: "Status must be active, inactive, or pending"

10. JSONPath Reference

Common patterns:

• $[*] - All items in root array
• $.data[*] - All items in data array
• $.items[*] - All items in items array
• $.attributes.name - Nested field access
• $.data - Single object (for detail views)
• $..name - Recursive descent (all name fields)
• $[0] - First item
• $[-1] - Last item
• $[?(@.status == 'active')] - Filter items

Generation Guidelines

When generating a TermStack YAML:

1. Understand the data source - API endpoints, CLI commands, or scripts
2. Define globals - API base URL and common variables
3. Create the start page - Usually a list/table view
4. Add detail pages - For viewing individual items
5. Set up navigation - Use next for Enter key, actions for shortcuts
6. Add styling - Color code important fields
7. Use correct context - Pass IDs/names via context, access directly by key name
8. Choose the right data source type - Use adapter: http|cli|script for single/periodic fetches, type: stream for real-time streaming
9. Select appropriate view - Table for lists, Text for details, Logs for streaming
10. Add transforms - Use Tera filters for formatting (timeago, filesizeformat)
11. Implement validation - Add rules for data integrity
12. Use conditional navigation - Route to different pages based on data type

Common Patterns

REST API Browser

List Page (table) → Detail Page (table/text) → Related Items (table)

File Browser

Directory (table) → Subdirectory (table) → File Content (text)
Use conditional navigation for files vs directories

Kubernetes Dashboard

Namespaces → Pods → Pod Details → Logs (streaming)

Log Viewer

Services (table) → Logs (logs view with filters)
Use stream adapter with follow mode

Multi-Source Dashboard

Users (merged from users + stats) → User Detail → User Activity

Timeout Formats

All timeout fields support these formats:

• Seconds: "30s", "5s"
• Minutes: "5m", "30m"
• Hours: "1h", "2h"
• Combined: "1h30m", "2m30s"

Running TermStack

termstack examples/your-config.yaml

Installation: If you don't have termstack installed, download it with:

# macOS Apple Silicon
curl -fsSL https://github.com/pa/termstack/releases/latest/download/termstack-macos-arm64.tar.gz \
  | tar -xz \
  && chmod +x termstack \
  && sudo mv termstack /usr/local/bin/termstack

# macOS Intel
curl -fsSL https://github.com/pa/termstack/releases/latest/download/termstack-macos-amd64.tar.gz \
  | tar -xz \
  && chmod +x termstack \
  && sudo mv termstack /usr/local/bin/termstack

# Linux x86_64
curl -fsSL https://github.com/pa/termstack/releases/latest/download/termstack-linux-amd64.tar.gz \
  | tar -xz \
  && chmod +x termstack \
  && sudo mv termstack /usr/local/bin/termstack

Navigation Keys

• Enter - Navigate to next page (defined by next)
• Esc - Go back
• Shift+A - Open action menu
• j/k or arrows - Move up/down
• g - Go to top
• G - Go to bottom
• / - Search (use %Column Name% term for column-specific search)
• q - Quit
• r - Refresh data
• f - Toggle filter (in logs view)

Tips for Best Results

1. Always specify items JSONPath - This tells TermStack where to find the array
2. Use descriptive context variable names - Makes templates easier to understand
3. Add timeouts - Prevent hanging on slow APIs or commands
4. Use refresh_interval for dashboards - Keep data current
5. Add confirmation for destructive actions - Use confirm field
6. Style based on data values - Use conditional styles for status, severity, etc.
7. Use transforms for readability - Format timestamps, file sizes, etc.
8. Test JSONPath expressions - Use online tools to verify paths
9. Add optional flag to non-critical data sources - Prevents failures
10. Use builtin actions - Leverage built-in functionality (help, search, refresh)

Troubleshooting Common Issues

Issue: "Command exited with status: 1" in Stream

Cause: Template variables in stream command are not being resolved correctly.

Solution:

# ❌ WRONG - Using global variable that may not be in scope
data:
  type: stream
  command: "kubectl"
  args: ["logs", "-f", "{{ pod_name }}", "-n", "{{ namespace }}"]

# ✅ CORRECT - Pass namespace explicitly in context
actions:
  - key: "ctrl+l"
    page: pod_logs
    context:
      pod_name: "{{ metadata.name }}"
      pod_namespace: "{{ metadata.namespace }}"

# Then in pod_logs page:
data:
  type: stream
  args: ["logs", "-f", "{{ pod_name }}", "-n", "{{ pod_namespace }}"]

Issue: Variables Not Available in Next Page

Cause: Using wrong syntax in context (templates in next.context or JSONPath in action.context).

Solution:

# ❌ WRONG - Template in next.context
next:
  context:
    name: "{{ metadata.name }}"  # Won't work!

# ✅ CORRECT - JSONPath in next.context
next:
  context:
    name: "$.metadata.name"

# ❌ WRONG - JSONPath in action.context
actions:
  - key: "ctrl+d"
    context:
      name: "$.metadata.name"  # Won't work!

# ✅ CORRECT - Template in action.context
actions:
  - key: "ctrl+d"
    context:
      name: "{{ metadata.name }}"

Issue: Can't Access Previous Page Data

Cause: Not understanding how page data is stored.

Solution:

# After navigating from "namespaces" page, entire selected row is stored
# Access it using the page name as prefix:
title: "Pods in {{ namespaces.metadata.name }}"

# OR extract specific fields in context:
# In namespaces page:
next:
  page: pods
  context:
    namespace: "$.metadata.name"  # Extract and store

# In pods page:
title: "Pods in {{ namespace }}"  # Use extracted value

Issue: Template Variables Empty/Undefined

Cause: Variable not in scope or wrong variable name.

Debug steps:

1. Check if variable is passed in context
2. Verify context syntax matches navigation type (next vs action)
3. Use page name prefix for previous page data: {{ pagename.field }}
4. Check variable resolution priority (current row > page contexts > globals)

Example:

# If you're getting empty {{ pod_name }}:

# Check 1: Was it passed in context?
actions:
  - key: "ctrl+l"
    context:
      pod_name: "{{ metadata.name }}"  # ✅ Passed

# Check 2: Is it being used in the right page?
pod_logs:
  title: "{{ pod_name }}"  # ✅ Should work if context passed

# Check 3: Try using source page prefix
pod_logs:
  title: "{{ pods.metadata.name }}"  # Alternative if context not working

Issue: JSONPath Not Extracting Data

Cause: Wrong JSONPath expression or data structure.

Solution:

# Test your JSONPath on actual data first
# If data is: {"metadata": {"name": "my-pod"}}

# ✅ CORRECT
context:
  name: "$.metadata.name"  # Extracts "my-pod"

# ❌ WRONG
context:
  name: "$.name"  # Won't find it (name is nested)
  name: "metadata.name"  # Missing $ prefix

Best Practices for Context

1. Always pass namespace with pod data:

   context:
     pod_name: "{{ metadata.name }}"
     pod_namespace: "{{ metadata.namespace }}"
   

2. Use consistent variable names across pages:

   # Good pattern:
   namespaces → namespace
   pods → pod_name, pod_namespace
   deployments → deployment_name
   

3. Extract data early in navigation chain:

   # In first page, extract what you'll need later
   next:
     context:
       namespace: "$.metadata.name"
       cluster: "$.metadata.clusterName"
   

4. Use descriptive context keys:

   # ✅ GOOD
   context:
     pod_name: "{{ metadata.name }}"
     pod_namespace: "{{ metadata.namespace }}"
   
   # ❌ BAD
   context:
     name: "{{ metadata.name }}"  # Too generic
     ns: "{{ metadata.namespace }}"  # Unclear abbreviation
