2f8eb4f068 LibJS: Implement non-ECMA-402 String.prototype.toLocale{Lower,Upper}Case 
In implementations without ECMA-402, these methods are to behave like
their non-locale equivalents.

2dc9ae00af LibJS: Use special case folding for String.prototype.to{Lower,Upper}Case 
Note we still have one String.prototype.toLowerCase test262 failure due
to not yet parsing WordBreakProperty.txt.

5a8f870594 LibJS: Implement RegExp.prototype [ @@replace ] with UTF-16 code units 
This also converts the GetSubstitution abstract operation take its input
strings as UTF-16 now that all callers are UTF-16 capable. This means
String.prototype.replace (and replaceAll) no longer needs UTF-8 and
UTF-16 copies of these strings.

code units.

5ac964d841 LibJS: Implement String.prototype.slice with UTF-16 code units 
This also implements String.prototype.slice more closely to the spec
(such as handling indices equivalent to Infinity).

eaa1360eee LibJS: Implement StringPad abstract operation with UTF-16 code units 
Affects String.prototype.padStart and String.prototype.padEnd.

Timothy Flynn
70f9c7e1c7 LibJS: Implement String.prototype.includes with UTF-16 code units 
This also implements String.prototype.includes more closely to the spec
(such as returning false when the search string is a RegExp object).
 2021-07-22 09:10:44 +02:00
Timothy Flynn
a05ce330b8 LibJS: Implement String.prototype.codePointAt with UTF-16 code units 
This also implements the CodePointAt abstract operation. This is needed
to handle invalid code units specific to the JavaScript spec, rather
than e.g. inserting replacement code units. This abstraction is public
because RegExp.prototype will also need it.

2bba20d123 LibJS: Report string properties using UTF-16 code units 
String length is reported as the number of UTF-16 code units, and string
indices are reported as the UTF-16 code units themselves.
 2021-07-22 09:10:44 +02:00
Timothy Flynn
0e25d2393f LibJS: Add UTF-16 tests to String.prototype methods that already work 
These methods did not require UTF-16 views, so just add test cases to
ensure they remain correct.

This also adds a couple of FIXME comments on tests that will fail even
with UTF-16 String.prototype support (for reasons such as lack of UTF-16
support in RegExp.prototype and Unicode case folding).

a2e734d202 LibJS: Report string length as the code point length, not byte length 
For example, U+180E is 3 bytes, but should have a string length of 1.
 2021-07-17 16:59:59 +01:00
Timothy Flynn
87848cdf7d AK: Track byte length, rather than code point length, in Utf8View::trim 
Utf8View::trim uses Utf8View::substring_view to return its result, which
requires the input to be a byte offset/length rather than code point
length.

5135f4000c LibJS: Implement RegExp.prototype [ @@matchAll ] 
This also allows String.prototype.matchAll to work, as all calls to that
method result in an invocation to @@matchAll.

35a2ba8ed8 LibJS: Implement RegExp.prototype [ @@search ] 
String.prototype.search is already implemented, but relies on the well-
known Symbol.search, which was not implemented.

2d0589f93c LibJS: Implement global RegExp.prototype.match 
Also rename the 'rx' variable to 'regexp_object' to match other RegExp
methods.
 2021-07-08 00:01:20 +01:00

b6b5adb47d LibJS: Implement RegExp.prototype.match with RegExpExec abstraction 2021-07-08 00:01:20 +01:00
Timothy Flynn
ec898a3370 LibJS: Implement RegExp.prototype.replace with RegExpExec abstraction 
Also rename the 'rx' variable to 'regexp_object' to match other RegExp
methods.

e0d26fff8c LibJS: Replace strings with the search value coerced to a string 
This only causes 1 new test262 test to pass. Other tests that rely on
this coercion fail due to receiving an unexpected value for 'this' when
invoking a functional replacement. For example:

    String/prototype/replaceAll/replaceValue-call-matching-empty.js

Receives 'undefined' for 'this' in the functional replacement invocation
but is expected to receive the global 'this'.

Timothy Flynn
81fec49ac3 LibJS: Evaluate replacement value before searching source string 
The String.prototype.replace spec requires evaluating the replacement
value (if it is not a function) before searching the source string.

Fixes 4 test262 tests.

65003241e4 LibRegex: Allow dollar signs in ECMA262 named capture groups 
Fixes 1 test262 test.
 2021-07-06 22:33:17 +01:00
Timothy Flynn
8fcdc57ae1 LibJS: Coerce named captures to an object before calling GetSubstitution 
Per the spec, before invoking the GetSubstitution abstraction, the named
capture groups (if not undefined) should be coerced to an object via the
ToObject abstraction.

424c7eaa40 LibJS: Fix replaceAll crash for overlapping search string positions 
The implementation of String.prototype.replaceAll cannot use AK's
implementation of String::find_all when finding the indices of the
search string in the source string. String::find_all will return indices
[0, 1] for String("aaa").find_all("aa") - i.e. it returns overlapping
results. This is not allowed by the JavaScript specification for
replaceAll.

e0c9f58b0c LibJS: Implement and use the GetSubstitution abstract operation 
Used by String.prototype.replace, String.prototype.replaceAll, and
RegExp.prototype [ @@replace ].
 2021-07-05 23:26:41 +01:00
Timothy Flynn
9f0aef6051 LibJS: Implement most of String.prototype.replaceAll 
This also renames ErrorType::StringMatchAllNonGlobalRegExp to
ErrorType::StringNonGlobalRegExp (removes "MatchAll") because this error
is now used in the same way from multiple operations.

596324ae9c LibJS: Rewrite String.raw() closer to the specification 
This includes not throwing a custom exception and using the
length_of_array_like abstract operation where required.

2299be474b LibJS: Add the String.fromCodePoint() method 2021-06-16 10:29:10 +01:00
Timothy Flynn
b6093ae2e3 LibJS: Implement String.prototype.substr according to the spec 
Fixes #6325

The JavaScript on the HTML Spec site that caused the crash is:
    window.location.hash.substr(1)

Of course, window.location.hash can be the empty string. The spec allows
for calling substr(1) on an empty string, but our partial implementation
wasn't handling it properly.

1db943e146 LibJS: Implement (mostly) String.prototype.match 
JavaScript has a couple of different ways to run a regular expression
on a string. This adds support for one more. :^)

2d8362cceb LibJS: Implement 'Relative Indexing Method' proposal (.at())

change - there isn't much to change here anyway. :^)
