preview <input> | Create or view preview entries. Without args, shows recent previews. With args, logs a new preview. |
generate <input> | Generate design elements. Without args, shows recent generations. With args, saves a new generation entry. |
convert <input> | Convert between formats. Without args, shows recent conversions. With args, logs a new conversion. |
harmonize <input> | Create color harmonies. Without args, shows recent harmonize entries. With args, saves a new harmony. |
contrast <input> | Check or log contrast values. Without args, shows recent contrast entries. With args, saves a new contrast entry. |
export <input> | Export design data. Without args, shows recent export entries. With args, logs a new export operation. |
random <input> | Generate random design elements. Without args, shows recent random entries. With args, saves a new random entry. |
browse <input> | Browse existing designs. Without args, shows recent browse entries. With args, logs a new browse action. |

Data Storage
All data is stored in ~/.local/share/banner/:
palette.log— Palette entries (timestamped)preview.log— Preview entriesgenerate.log— Generation entriesconvert.log— Conversion entriesharmonize.log— Harmony entriescontrast.log— Contrast entriesexport.log— Export entriesrandom.log— Random generation entriesbrowse.log— Browse activity entriesmix.log— Mix entriesgradient.log— Gradient entriesswatch.log— Swatch entrieshistory.log— Full command history with timestamps
Each entry is stored as YYYY-MM-DD HH:MM|<input> (pipe-delimited).
Requirements
- Bash 4+ (uses
localvariables and standard Unix utilities) - No external dependencies or API keys required
When to Use
- Building a color palette — Use
paletteto log and iterate on color combinations for a design project. - Previewing design elements — Use
previewto record design preview notes before committing to final assets. - Generating design assets — Use
generateto log generation parameters and track what you've created over time. - Creating gradients and swatches — Use
gradientandswatchto catalog reusable gradient definitions and color swatch collections. - Auditing design history — Use
stats,recent,search, andexportto review past design decisions, find old entries, and export data for reporting.
Examples
# Add a new palette entry
banner palette "#FF5733 sunset warm tones"
# View recent palette entries
banner palette
# Generate a design element and log it
banner generate "header-image 1920x1080 blue-gradient"
# Create a gradient entry
banner gradient "linear #000 to #FFF 90deg"
# Mix two color references
banner mix "#FF0000 + #0000FF = purple blend"
# Search across all categories for a keyword
banner search "sunset"
# Show summary stats
banner stats
# Export all data as JSON
banner export json
# Check system status
banner status
Output
All commands print results to stdout. Each logging command confirms the save and shows the total entry count for that category. Use shell redirection to capture output: banner stats > report.txt.
