ReadArgs provides the @readArgs@ IO action, which lets you tell the compiler |
| 26 |
to parse the command line arguments to fit the type signature you give. |
| 27 |
|
| 28 |
For example @(a :: Int, b :: String, c :: Float) <- readArgs@ would |
| 29 |
parse the first runtime argument as an @Int@, the second as a @String@ (no |
| 30 |
quotes required) and the third as a @Float@. |
| 31 |
|
| 32 |
If the runtime arguments are incompatible with the type signature, |
| 33 |
then a simple usage statement is given of the types needed. |
| 34 |
|
| 35 |
Continuing the previous example, if it was used in a |
| 36 |
program named @Example@, the error message for the above |
| 37 |
action would be: |
| 38 |
|
| 39 |
@ |
| 40 |
usage: Example Int String Float |
| 41 |
@ |
| 42 |
|
| 43 |
Any type that has both @Typeable@ and @Read@ instances |
| 44 |
can be used. @Char@, @String@, and @Text@ are handled specially so that |
| 45 |
command line arguments for both do not require quotes (as their |
| 46 |
@Read@ instances do). A special instance is provided for @FilePath@ so |
| 47 |
that no constructor or quotes are required. |
| 48 |
|
| 49 |
@readArgs@ also supports optional arguments and variadic arguments. |
| 50 |
Optional arguments are specified using @Maybe@, and variadic arguments |
| 51 |
using a list. @(a :: Int, b :: Maybe String, c :: [Float]) <- readArgs@ |
| 52 |
would successfully parse any of the following sets of command line arguments: |
| 53 |
|
| 54 |
@ |
| 55 |
Example 1 |
| 56 |
Example 1 2 3 4 |
| 57 |
Example 1 foo |
| 58 |
Example 1 foo 2 3 4 |
| 59 |
@ |
| 60 |
|
| 61 |
But not |
| 62 |
|
| 63 |
@ |
| 64 |
Example |
| 65 |
Example foo |
| 66 |
Example 1.0 |
| 67 |
@ |
| 68 |
|
| 69 |
Usage statements for optional and variadic arguments use command-line |
| 70 |
parlance: |
| 71 |
|
| 72 |
@ |
| 73 |
usage: Example Int [String] [Float..] |
| 74 |
@ |
| 75 |
|
| 76 |
Note that both optional and variadic parsers are greedy by default |
| 77 |
(so @Example 1 2 3 4@ was parsed as @(1, "2", [3.0,4.0])@. They |
| 78 |
may both be made non-greedy through use of the @NonGreedy@ constructor: |
| 79 |
|
| 80 |
@ |
| 81 |
( a :: Int |
| 82 |
, NonGreedy b :: NonGreedy Maybe String |
| 83 |
, NonGreedy c :: NonGreedy [] Float |
| 84 |
) <- readArgs |
| 85 |
@ |
