Hi
oct-documentation points to Integer.
Where do I find these docs there??
thank you Opti
hello,
oct-documentation points to Integer.
Mine says `Kernel#Integer':
% ri oct
[…]
If str starts with 0, radix indicators are honored. See
Kernel#Integer.
Where do I find these docs there??
`Kernel#Integer' or `#Integer' (#Integer is the method, Integer is
the class) :
% ri #Integer
= #Integer
(from ruby core)
=== Implementation from Kernel

Hi,
I know, but: could you paste me the text with the description please
(e.h. 0x...) ??
we are NOT speaking of Integer(10,16), BUT 0x10.oct !
(I said it's not documented anywhere...)
thanks Opti

------------------------------------------------------------------------
str.oct -> integer
------------------------------------------------------------------------
Treats leading characters of str as a string of octal digits (with
an optional sign) and returns the corresponding number. Returns 0 if
the conversion fails.
"123".oct #=> 83
"-377".oct #=> -255
"bad".oct #=> 0
"0377bad".oct #=> 255
If str starts with 0, radix indicators are honored. See Kernel#Integer.
$ ri Kernel#Integer
(from ruby core)
------------------------------------------------------------------------
Integer(arg, base=0, exception: true) -> integer or nil
------------------------------------------------------------------------
... If arg is a String, when base is omitted or equals zero, radix
indicators (0, 0b, and 0x) are honored. ...
Integer("0x1a") #=> 26

ok - thank you
But: why is this not shown with ri Integer?? (therefore I didn't find it!)

If the documentation has not been generated locally, `ri` will not find
the documentation.
If you do `ri Array` you may find that documentation missing as well
(except for any documentation that may have been generated for gems that
you have installed).

How can I rebuild the index for ri?
Kernel#Integer is shown,
ri Integer does not include that item, (or is this a wanted behaviour?)

It probably was never built for the core library.
Some folks have had luck doing
$ gem install rdoc-data
$ rdoc-data --install
I use RVM and so I will usually do:
$ rvm docs generate-ri

Integer should not include that item, it comes from String.
>> "0x52".oct => 42
The documentation as shown by `ri 'String\#oct'`:
# String#oct
(from ruby site)
