This module is a wrapper around the ~Getopt~ library and helps to
|
||||
define command-line arguments.
|
||||
|
||||
Here is an example of how to use this module.
|
||||
First, define the specification:
|
||||
#+begin_src ocaml :tangle no
|
||||
let open Command_line in
|
||||
begin
|
||||
set_header_doc (Sys.argv.(0) ^ " - One-line description");
|
||||
set_description_doc "Long description of the command.";
|
||||
set_specs
|
||||
[ { short='c'; long="check"; opt=Optional;
|
||||
doc="Checks the input data";
|
||||
arg=Without_arg; };
|
||||
|
||||
{ short='b' ; long="basis" ; opt=Mandatory;
|
||||
arg=With_arg "<string>";
|
||||
doc="Name of the file containing the basis set"; } ;
|
||||
|
||||
{ short='m' ; long="multiplicity" ; opt=Optional;
|
||||
arg=With_arg "<int>";
|
||||
doc="Spin multiplicity (2S+1). Default is singlet"; } ;
|
||||
]
|
||||
end;
|
||||
#+end_src
|
||||
|
||||
Then, define what to do with the arguments:
|
||||
#+begin_src ocaml :tangle no
|
||||
let c =
|
||||
Command_line.get_bool "check"
|
||||
in
|
||||
|
||||
let basis =
|
||||
match Command_line.get "basis" with
|
||||
| Some x -> x
|
||||
| None -> assert false
|
||||
in
|
||||
|
||||
let multiplicity =
|
||||
match Command_line.get "multiplicity" with
|
||||
| None -> 1
|
||||
| Some n -> int_of_string n
|
||||
in
|
||||
#+end_src
|
||||
|
||||
** Type
|
||||
|
||||
- Short option: in the command line, a dash with a single character
|
||||
(ex: =ls -l=)
|
||||
- Long option: in the command line, two dashes with a word
|
||||
(ex: =ls --directory=)
|
||||
- Command-line options can be ~Mandatory~ or ~Optional~
|
||||
- Documentation of the option is used in the help function
|
||||
- Some options require an argument (~ls --ignore="*.ml"~ ), some
|
||||
don't (~ls -l~) and for some arguments the argument is optional
|
||||
(~git --log[=<n>]~)

||||
