Warning
Symbols prefixed with either RBIMPL or rbimpl are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will.
Note
To ruby-core: remember that this header can be possibly recursively included from extension libraries written in C++. Do not expect for instance __VA_ARGS__ is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98.

Function Documentation

◆ rb_enc_is_newline()

static bool rb_enc_is_newline ( const char *  p,
const char *  e,
rb_encoding enc 
)
inlinestatic

Queries if the passed pointer points to a newline character.

What is a newline and what is not depends on the passed encoding.

Parameters
[in]pPointer to a possibly-middle of a character.
[in]endEnd of the string.
[in]encEncoding.
Return values
falseIt isn't.
trueIt is.

Definition at line 43 of file ctype.h.

◆ rb_enc_isalnum()

static bool rb_enc_isalnum ( OnigCodePoint  c,
rb_encoding enc 
)
inlinestatic

Identical to rb_isalnum(), except it additionally takes an encoding.

Parameters
[in]cA code point.
[in]encAn encoding.
Return values
trueenc classifies c as "ANUM".
falseOtherwise.

Definition at line 166 of file ctype.h.

◆ rb_enc_isalpha()

static bool rb_enc_isalpha ( OnigCodePoint  c,
rb_encoding enc 
)
inlinestatic

Identical to rb_isalpha(), except it additionally takes an encoding.

Parameters
[in]cA code point.
[in]encAn encoding.
Return values
trueenc classifies c as "ALPHA".
falseOtherwise.

Definition at line 96 of file ctype.h.

◆ rb_enc_isascii()

static bool rb_enc_isascii ( OnigCodePoint  c,
rb_encoding enc 
)
inlinestatic

Identical to rb_isascii(), except it additionally takes an encoding.

Parameters
[in]cA code point.
[in]encAn encoding.
Return values
falsec is out of range of ASCII character set in enc.
trueOtherwise.

Definition at line 82 of file ctype.h.

◆ rb_enc_iscntrl()

static bool rb_enc_iscntrl ( OnigCodePoint  c,
rb_encoding enc 
)
inlinestatic

Identical to rb_iscntrl(), except it additionally takes an encoding.

Parameters
[in]cA code point.
[in]encAn encoding.
Return values
trueenc classifies c as "CNTRL".
falseOtherwise.

Definition at line 138 of file ctype.h.

◆ rb_enc_isctype()

static bool rb_enc_isctype ( OnigCodePoint  c,
OnigCtype  t,
rb_encoding enc 
)
inlinestatic

Queries if the passed code point is of passed character type in the passed encoding.

The "character type" here is a set of macros defined in onigmo.h, like ONIGENC_CTYPE_PUNCT.

Parameters
[in]cAn OnigCodePoint value.
[in]tAn OnigCtype value.

inlinestatic

Identical to rb_isdigit(), except it additionally takes an encoding.

Parameters
[in]cA code point.
[in]encAn encoding.
Return values
trueenc classifies c as "DIGIT".
falseOtherwise.

Definition at line 208 of file ctype.h.

static bool rb_enc_islower ( OnigCodePoint  c,
rb_encoding enc 
)
inlinestatic

Identical to rb_islower(), except it additionally takes an encoding.

Parameters
[in]cA code point.
[in]encAn encoding.
