Fix #167: gutter numbers align with wrapped-line starts
- splitLines(): join .codeline blocks with "" not "\n" — newline text
  nodes under pre-wrap rendered an extra line box per logical line, so
  every gutter number drifted one row per line
- renumber(): geometry-driven placement — one gutline per visual row of
  the code body, each number assigned to the row matching its line's
  measured offsetTop; verified second pass re-runs if a partially-filled
  last wrapped row reflows after the gutter rebuild
- app.css: mobile media query gives .code .gutter the same 13px font as
  .code so gutter rows and code rows share one line box at 375px

Verified in local build with headless chromium (long unbroken token on
line 5, wrap ON): all numbers align with line starts, no misalignment,
no horizontal scroll at 1400x900 and 375x812.

Get Started

Docker

docker run -p 8080:8080 -v palette-data:/data git.archfox.org/poslop/palette

The SQLite database lives in the /data volume inside the container.

Docker Compose

See docker-compose.yml for a ready-to-use example with every environment variable documented, including which are required (only the /data volume) and which are optional.

Build from source

Requires Go 1.27+.

go build -o palette ./cmd/palette
./palette
# open http://localhost:8080

Configuration

Setting Default Description
PALETTE_ADDR :8080 Listen address

PALETTE_MAX_TEXT 5242880 Max paste size in bytes (5 MB)
PALETTE_MAX_ITEM 26214400 Max can item size in bytes (25 MB)
PALETTE_ADMIN_KEY generated Admin key; if unset a 32-char hex key is generated and persisted to <db-dir>/admin-key (0600)
