DESCRIPTIONeliomc, eliomcp and eliomopt are wrapper around the OCaml compiler that ease the compilation of the server part of projects based on the Eliom framework. They respectively accept the same set of option than the ocamlc(1),ocamlcp(1) and ocamlopt(1) compilers plus the specific ones described in the OPTIONS section.
js_of_eliom is a wrapper around the OCaml and Js_of_ocaml compilers that ease the compilation of the client part of projects based on the Eliom framework. It accepts the same set of option than the ocamlc(1) compiler plus the specific ones described in the OPTIONS section.
eliomdep is a wrapper around ocamldep(1) that handles dependencies of an .eliom source files. It accepts the same set of options plus the specific ones described in the OPTIONS section. It makes the assumption that server-side compiled modules of OCaml files located in this directory subtree are in directory _server (with same subdirectories structure) (resp. in directory _client for client-side compiled modules).
eliompp (EXPERIMENTAL) is a preprocessor which remove specific sections, depending on the given option. The option -client will remove all the top-level parts and server sections and the option -server will remove only the client sections.

It automatically extracts the commentaries from the desired sections.
is currently experimental, and you could find some undefined behaviours.
(see http://ocsigen.org/eliom/manual/workflow-compilation). Some well
known bugs are:
your files should always begin with a value and not with a comment. Otherwise,
camlp4 won't output the commentaries.
sometimes, comment node are not attached as expected. That's because
camlp4 (sometimes) remove extra new line between value elements.
COMPILING ELIOM SOURCE FILES
The compilation of files with a .eliom extension is achieved in three steps: infer the type of value sent by the server to the client; compile the server part of the code and compile the client part. The first two steps can be realised with eliomc and the last one with js_of_eliom.
Both tools produce a .cmo file named as the original .eliom file. To avoid overwriting the .cmo representing the server part with .cmo of the client part, files generated by eliomc or eliomopt are stored by default in a subdirectory named _server and files generated by js_of_eliom are stored in a subdirectory named _client. Those default directories could be respectively overridden by the environment variables ELIOM_SERVER_DIR and ELIOM_CLIENT_DIR.
The types infered by eliomc for values sent by the server to the client are stored in an intermediate files named as the original .eliom file and whose extension is .type_mli. That file is required by js_of_eliom for compiling the client part of the .eliom file. The eliomdep tool correctly generate dependencies that intermediate file for the server .cmo and the client .cmo.
OPTIONS-eliom-inc <dir> Add <dir> to the list of eliom include directories (eliomdep only).
- -dir <dir>
- Specify the target directory for generated files
- -package <name>
- This is the same option as the ocamlfind one.
- -predicates <p>
- This is the same option as the ocamlfind one.
- Do not load commonly used syntax extensions (deriving, lwt, js_of_ocaml, tyxml).
- Use type_conv syntax extensions instead of deriving one. It has no effect if used in conjunction with -no-autoload.
- -ppopt <opt>
- Append <opt> to preprocessor invocation.
- -jsopt <opt>
- Append <opt> to js_of_ocaml invocation (js_of_eliom only).
- -infer <opt>
- For .eliom file, only generate the intermediate .type_mli file (eliomc and eliomopt only).
- -noinfer <opt>
- For .eliom file, do not generate the intermediate .type_mli file (eliomc and eliomopt only).
- -help or --help
- Display a short usage summary and exit.
EXAMPLESThe compilation of an Eliom projects composed of a server specific file named server.ml, a client specific file named client.ml and two common files name base.eliom and main.eliom, could be achieved with the following commands:
eliomc -a -o appl.cma server.ml base.eliom main.eliom
js_of_eliom -o appl.js client.ml base.eliom main.eliom
To avoid recompiling the whole project each times, this could be split in multiple steps:
eliomc -c server.ml
eliomc -c base.eliom
eliomc -c main.eliom
eliomc -a -o appl.cma _server/server.cmo _server/base.cmo _server/main.cmo
js_of_eliom -c client.ml
js_of_eliom -c base.eliom
js_of_eliom -c main.eliom
js_of_eliom -o appl.js _client/client.cmo _client/base.cmo _client/main.cmo
