A ocaml_library() rule builds a native and a bytecode libraries from the supplied set of OCaml source files and dependencies.
Parameters
name
: name of the targetdefault_target_platform
: specifies the default target platform, used when no platforms are specified on the command linetarget_compatible_with
: a list of constraints that are required to be satisfied for this target to be compatible with a configurationcompatible_with
: a list of constraints that are required to be satisfied for this target to be compatible with a configurationexec_compatible_with
: a list of constraints that are required to be satisfied for this target to be compatible with an execution platformvisibility
: a list of visibility patterns restricting what targets can depend on this onewithin_view
: a list of visibility patterns restricting what this target can depend onmetadata
: a key-value map of metadata associated with this targettests
: a list of targets that provide tests for this onemodifiers
: an array of modifiers associated with this targetcompiler_flags
: The set of additional compiler flags to pass to ocaml compiler. It supports specifying ppx (see for example).deps
: The set of dependencies of this rule. It could include references to ocaml_library and cxx_library rules.platform_deps
: Platform specific dependencies. These should be specified as a list of pairs where the first element is an un-anchored regex (in java.util.regex.Pattern syntax) against which the platform name is matched, and the second element is a list of dependencies (same format asdeps
) that are exported if the platform matches the regex. Seedeps
for more information.srcs
: The set of source files to be compiled by this rule. It supports *.ml, *.mli, *.mly, *.mll, and *.c files. (see this test as C interop example and this test as parser and lexer example).
