TemplateDict

An Args-like structure for use in ctx.actions.expand_template(), which allows for deferring evaluation of values till the execution phase.

Members

TemplateDict TemplateDict.add(key, value)

Add a String value

Parameter	Description
`key`	required A String key
`value`	required A String value

TemplateDict TemplateDict.add_joined(key, values, *, join_with, map_each, uniquify=False, format_joined=None, allow_closure=False)

Add depset of values

Parameter	Description
`key`	required A String key
`values`	depset; required The depset whose items will be joined.
`join_with`	required A delimiter string used to join together the strings obtained from applying `map_each`, in the same manner as `string.join()`.
`map_each`	callable; required A Starlark function accepting a single argument and returning either a string, `None`, or a list of strings. This function is applied to each item of the depset specified in the `values` parameter
`uniquify`	default is `False` If true, duplicate strings derived from `values` will be omitted. Only the first occurrence of each string will remain. Usually this feature is not needed because depsets already omit duplicates, but it can be useful if `map_each` emits the same string for multiple items.
`format_joined`	string; or `None`; default is `None` An optional format string pattern applied to the joined string. The format string must have exactly one '%s' placeholder.
`allow_closure`	default is `False` If true, allows the use of closures in function parameters like `map_each`. Usually this isn't necessary and it risks retaining large analysis-phase data structures into the execution phase.
