# Compile a flatbuffer to typescript.

# flatc_include_dirs (optional)
|
|
# Specifies the directories which FlatBuffers compiler uses to find
|
|
# included .fbs files in. Almost always should be empty.
|
|
#
|
|
# The list always has an implicit first item corresponding to the root of
|
|
# the source tree. This enables including .fbs files by absolute path.
|
|
#
|
|
# The compiler will try the directories in the order given, and if all
|
|
# fail it will try to load relative to the directory of the schema file
|
|
# being parsed.

#
|
|
# deps (optional)
|
|
# Additional dependencies.

# Example:
|

# ts_flatbuffer("foo_ts") {
|
|
# sources = [
|
|
# "foo.fbs",
|
