10 The findlib library provides a scheme to manage reusable software components
11 (packages), and includes tools that support this scheme. Packages are
12 collections of OCaml modules for which metainformation can be stored. The
13 packages are kept in the filesystem hierarchy, but with strict directory
14 structure. The library contains functions to look the directory up that stores
15 a package, to query metainformation about a package, and to retrieve dependency
16 information about multiple packages. There is also a tool that allows the user
17 to enter queries on the command-line. In order to simplify compilation and
18 linkage, there are new frontends of the various OCaml compilers that can
19 directly deal with packages.
21 Together with the packages metainformation is stored. This includes a version
22 string, the archives the package consists of, and additional linker options.
23 Packages can also be dependent on other packages. There is a query which finds
24 out all predecessors of a list of packages and sorts them topologically. The
25 new compiler frontends do this implicitly.
27 Metainformation can be conditional, i.e. depend on a set of predicates. This is
28 mainly used to be able to react on certain properties of the environment, such
29 as if the bytecode or the native compiler is invoked, if the application is
30 multi-threaded, and a few more. If the new compiler frontends are used, most
31 predicates are found out automatically.
33 There is special support for scripts. A new directive, "#require", loads
34 packages into scripts. Of course, this works only with newly created toploops
35 which include the findlib library.
