              [-m] infile [-m infile] [-t target] [outfile.kmx|outfile.js [error.log]]
              [-extract-keyboard-info field[,field...]]

General compiler parameters

infile

A .kmn file (Keyboard Source), .kps file (Package Source), or .kpj (project). Required in compiler mode. If a .kpj is specified, the .kpj will determine output paths and all files referenced in the project will be built (see -t). For validation mode, can be a .keyboard_info file.

outfile.kmx

Generate an output file for Windows/macOS; can only be specified for a .kmn infile. Optional; if omitted, generates an output file with the same base name as the input file.

outfile.js

Generate an output file for KeymanWeb/touch devices; can only be specified for a .kmn infile. Optional; if omitted for a .kmn input, no JavaScript keyboard will be built.

error.log

Write output to a text file specified by error.log instead of stdout.

-s

Mostly silent; don't print information-level messages

-ss

Fully silent; don't print anything except fatal internal errors

-nologo

Don't print the compiler description

-c

Clean target(s) instead of building (only for .kpj)

-d

Include debug information

-w

Treat warnings as errors

-t target

Build only the target file from the project (only for .kpj)

JSON .keyboard_info compile targets

-v[s]

Validate infile against source schema

-vd

Validate infile against distribution schema

-m

Merge information from infile (can be .kmp and .js) into .keyboard_info output file

-m-validate-id

Validate the id against the .js, .kmx and .kmp filenames when merging

-extract-keyboard-info

Print json data .keyboard_info for build script integration.

-source-path

Specify path to add to the sourcePath field in the .keyboard_info output file

-schema-path

Specify path to the keyboard_info json schema definitions. If not specified, then defaults to same folder as kmcomp.exe
