Overview
::desc build packages
Builds a list of ‘package’ recipes into packages. Packages are exported to a directory named like the recipe. Build prints the package dir for each recipe to stdout.
Recipes are added to the package as the ‘run’ executable and they are automatically configured with a package file corresponding to the recipe, if it exists.
For example:
$ echo "write 'echo ' + attrs['msg']" > recipe.rb
$ echo "msg: hello world" > recipe.yml
$ linecook build recipe.rb
/path/to/pwd/recipe
$ /path/to/pwd/recipe/run
hello world
The input directory containing the package files and the output directory for the packages may be specified with options.
Package Specs
Package specs can be provided instead of recipes. Specs are comma-separated strings like ‘package_file,recipe_file,export_dir’ that allow full control over the building of packages. Package files
For example:
$ echo "write 'echo ' + attrs['msg']" > recipe.rb
$ echo "msg: hello world" > input.yml
$ linecook build input.yml,recipe.rb,output
/path/to/pwd/output
$ /path/to/pwd/output/run
hello world
Providing ‘-’ as an input will cause stdin to be read for additional inputs. In that way a CSV file can serve as a manifest for the packages built by this command.
