Discussion
Number formatting –
WH
Couple of
approaches
C printf
style
Fixed pattern string with fixed
grammar. This works but looking
towards the future this could constrain the language. To allow extension this would take
considerable work.
Alternative
See WH’s
doc
Questions
Could they be folded into one
function?
This could affect
extensibility. It could be added to
the prototype
Boolean yes I want scientific or
no I don’t as an additional argument to a generic
function
Are we going for simplicity or
power?
Should lean towards simplicity and
leave the complex/powerful features to the I18N library
Comments
Rename insertCommas to be
insertSeparator to get round the international issues
The simple non locale specific
functions would be a good basis for the core language and leave the locale
dependent functions to the I18N library.
MC walked through the Java
standard example
Format(before,after,explaces,exdigits,exform,exround)
from the Java spec was discussed
Group leaned towards using the
simpler features (1st page of WH’s document)
Where should this proposal go –
the ECMAScript 3rd edition or post 3rd
edition?
If there is a document that is
agreeable to the group and tc39 has finished the rest of the 3rd
edition of the document it will be in the 3rd
Edition
Waldemar Horwat will provide this
spec for the next meeting
Dates
Functions to get the date and time
from a specific date
A simple solution (that will not
impact I18N) will be proposed for Edition 3
Richard Gillam (IBM) will look
after this
Undefined
HermanV proposed solution
(**insert Hermans text here**)
Herman will provide text to Bill
Gibbons for inclusion in the spec
Meeting on
3/30
Scope, conformance and references
– assumed to be agreed so no changes required. I18n might require a change to
references
Source text
I18N will require some
changes
7, 7.1,7.2
will be effected by I18N which
will covered this afternoon
7.4 Tokens
Regular expressions will require a
change
NB will address WH’s concerns over
grammar and it’s effects on this section
WH will try to get a proposal for
the next meeting
RegExp as inconsistent as written
up now and not integrated into the language
RegExp requires considerable more
work
7.4.2
Keywords
Move try, catch, throw from
reserved words to keywords
7.4.3Future Reserved
Words
See above
7.5
Identifiers
WH is still on the hook for this
and there will be some I18N issues (**insert here**)
7.7.5 Regular Expression
Literals
Connected with WH’s work for
7.4
NB to check to see if WH’s work
will effect this
Any regular expression work will
wait until WH work is presented. NB presented some changes which will be
discussed later
7.8 Automatic semi-colon
insertion
RegExp anomalies
again!
Example:
A
/B
Is this a division or a regular
expression?
In the MSFT implementation
priority is given to division. If a
/ is in a position where a division would be illegal the MSFT implementation
attempts a regular expression.
This mechanism was agreed as the
way forward for the standard
WH will provide a spec for
this
7.8.1

Bill Gibbons has not done any work
on this but will get a spec for the next meeting

11.1 Primary
Expressions
MM has a document on the behavior
of missing elements in array initializers
For Object
initializers
MM to present document later **insert link
here**
15.1 Global
object
Needs constructors. Again RegExp impacts this object and
needs to be added to the spec. NB
will do this for the next meeting.
15.1.2.1 Eval
(x)
BG will check to see if there is a
difference from V1. If there is a
difference then BG will bring back proposal to group. BG will verify with doc for next
meeting
15.1.2.8
URIencode()
Rok Yu will do
this
15.1.2.9
URIdecode()
Rok Yu will do
this
15.1.4.2
RegExp
15.2.4.3

Deferred
It’s not in the document so will
be deleted from the 3rd edition doc
15.4.4.3 Array
prototype.toSource
Deferred
It’s not in the document so will
be deleted from the 3rd edition doc
Change to be made to the document
for hasDelegate
15.5.4.9
String.prototype.match
15.5.4.10
String.prototype.replace
WH asks about special treatment of
specific chars ($,&,^ etc).
What should be the behavior?
NB will look at this issue and
investigate both implementations
15.5.4.11
String.prototype.search
15.5.4.14
String.prototype.split
15.? Call

16 Errors
Timing of
errors
Section as it currently exists is
probably not worth addressing
Language which provides meta
semantics for how errors happen.
Discussion on what needs to be done with this
section
WH will provide alternative text
for the next meeting
Modularity
Agreed to be post 3rd
Edition
I18N
Will be dealt with this afternoon
**insert link**
Library will not be in the
3rd Edition and since it will be part of a technical report is not
linked to the 3rd Edition
Atomic

Agreed to be post 3rd
Edition
Other
enhancements
Closures and nested functions –
done
RegExp Perl5 features –
done
Exceptions and runtime
errors
Should be added and MM will look
after this
Runtime errors as catchable
exceptions
Catch guards are deferred post

Class Hierarchy for errors should
be in 3rd Edition and MM will look after this

Discussion over allowing trailing

C 89 doesn’t allow trailing
comma’s
But most compilers allow this as
an extension
Discussion on the implementation
details and how it would effect usability
The group agreed on MM
proposal
Move to be function
agreed
Regular

NB presented changes to Hermans
original document
15.6.4.9
String.Match
Move to content
agreed
15.6.4.10
String.prototype.replace
Need to check what MSFT, NSCP and
PERL do before it can be moved to content agreed.
15.6.4.11
String.prototype.search
Some clarification required for
the use of last index
15.6.4.14
String.prototype.split
Both implementations differ from
the spec
NB will look into this further and
send mail with an example covering a*? and other areas of the method
usage
Need to change the limit line
4
How to deal with sub
expressions
15.7.1 Regular Expression Pattern
Matching
^ and $ explanations are
incorrect. These are special
everywhere not just at the beginning of a regular
expression.
{} the explanation is
incorrect. MSFT throw syntax errors
if they are not matched. So you
need to escape them with \\ otherwise implementation
defined
Much discussion on ignorecase and
its implications when used on foreign language systems
The recommendation is to not deal
with conversion of expanding characters and the user can convert the string
before the regular expression
\d and \w remain
unchanged
\s will change to ensure that it
supports all Unicode categories
I18N will put together a proposal
for the best way forward for this problem
15.7.2
No changes
Rok Yu noted that 15.7.2.1 and
15.7.3.1 (and 15.7.2.2 and 15.7.3.2) are effectively the same other than an
optional argument. Should we be
merging these into 1 section to assist with readability/lack of
verbosity?
Pattern description should
explicitly show that it should be a string and likewise for
flags
NB will attempt to
merge
15.7.4
Move to content
agreed
15.7.4.1
Move to content
agreed
15.7.4.2
Move to content
agreed
15.7.5 Properties of the RegExp
prototype object
NB will work on clarification of
the description
15.7.5.3
RegExp.prototype.exec
The change covers the use of the
global property and its effect on case.
Also covers the change to the input property
15.7.6.3
Reword this as though it’s
string.toUpperCase to deal with locale specific
information
