|
| Interpret a string argument as a boolean.
|
| The definition of LocaleIndependentAtoi()
| requires that non-numeric string values
| like “foo”, return 0. This means that
| if a user unintentionally supplies
| a non-integer argument here, the return
| value is always false. This means that
|
| -foo=false does what the user probably
| expects, but -foo=true is well defined
| but does not do what they probably expected.
|
| The return value of LocaleIndependentAtoi(…)
| is zero when given input not representable
| as an int.
|
| For a more extensive discussion of this
| topic (and a wide range of opinions on
| the Right Way to change this code), see
| PR12713.
|
| Interpret -nofoo as if the user supplied
| -foo=0.
|
| This method also tracks when the -no
| form was supplied, and if so, checks
| whether there was a double-negative
| (-nofoo=0 -> -foo=1).
|
| If there was not a double negative, it
| removes the “no” from the key and returns
| false.
|
| If there was a double negative, it removes
| “no” from the key, and returns true.
|
| If there was no “no”, it returns the string
| value untouched.
|
| Where an option was negated can be later
| checked using the
|
| IsArgNegated() method. One use case
| for this is to have a way to disable options
| that are not normally boolean (e.g.
| using -nodebuglogfile to request that
| debug log output is not sent to any file
| at all).
|
| Sets the params returned by Params()
| to those for the given network.
