CLI options#

Workflow#

The CLI entry point has three document commands and a language-server command:

1laymesh validate <file.lay> [--warnings show|hide]2laymesh inspect <file.lay> --json [--warnings show|hide]3laymesh render <file.lay> -o <output.svg|pdf|png|jpg|tif|webp|bmp|gif|ico|pnm|tga> [--dpi <positive-number>] [--warnings show|hide]

Use cargo run --release --locked -p laymesh-cli -- as the prefix in this workspace. -o and --output are equivalent; the extension selects the format; --dpi applies to all raster formats. Successful validation prints dimensions and the top-level placement count. Successful rendering prints the output path. Warnings go to stderr without changing a success exit code of 0. Source/render errors exit 1, usage errors exit 2. The CLI renders to a temporary file before renaming to the destination, avoiding partial outputs on ordinary failures. See actual stdout.

LSP / version / help#

1laymesh lsp --stdio2laymesh --version3laymesh --help

lsp runs a long-lived JSON-RPC server on stdin/stdout. Keep stdout reserved for protocol messages. --version/-V and --help/-h are standalone commands. --warnings show|hide overrides LAYMESH_WARNINGS; inspect retains all diagnostic data even if display is hidden.

Raster formats include PNG, JPEG, TIFF, WebP, BMP, GIF, ICO, PNM and TGA. See Export formats and encoding options for quality, compression, matte and WebP mode options.
