Update the Git Browser entry in Tools menu. Selecting "Git Browser" opens a Git Browser. If infrastructure has not previously been installed, prompt and show the proposed installation. If the user does not confirm, do nothing.

Also remove the Metacello item from the Tools menu.

Menu icons are updated in the Tools menu, but note that the the Git browser needs to have a #defaultWindowColor in order for colorful windows to work as expected. For example, add this in package Squit:

SquitBrowser>>defaultWindowColor
^ (Color r: 0.6 g: 0.7 b: 0.6)

Better this is well implemented once in the interpreter than potentially badly implemented many times in plugins. Check the C string argument for null to avoid passing null to strlen:, which can crash.

Replace the code duplication from xLetter which was the same as the step method.
This is done in order to allow customization of the step method without having to modify both places. All other methods already use the explicit step method.
"open code step for speed" no longer applies anyways as a method call is fast enough nowadays.

vVarious refactorings and fixes:
- renamed #rangeType: and #rangeType:start:end: to #addRangeType: and #addRangeType:start:end:
- renamed #resolve: and #resolvePartial: to #parseIdentifier and #parsePartialIdentifier
- renamed #skipBigDigits: and #isBigDigit:base: to #skipDigitsBase: and #isDigit:base:
- renamed #pushTemporary: and #pushArgument: to #parseTemporary: and #parseArgument: as those methods do actual parsing
- renamed #error to #fail to be consistent with #failWhen: and #failUnless:
- introduced #currentTokenType as an instance variable which is lazily initialized by the method of the same name. It categorizes the current token and therefore replaces various #is* methods.
- arguments and temporaries are OrderedCollections instead of Dictionaries. Each element of these collections holds the variables for the scope at the given level. This also replaces blockDepth.
- unified method and block temporary parsing into #parseTemporaries. This also fixes various issues with empty temporary lists.
- detect reserved keywords as invalid in arguments and temporaries
- detect when assignment to reserved keywords is attempted
- detect arguments and temporaries trying to shadow each other

Here is an idea to make this work:

#(1 1 2 2 3 4) asSet collect: [:ea | ea -> ea] as: Dictionary

See inbox CollectionsTests-pre.314.mcz. Not as fast as before, though. :-)

Complements System-mt.1073.

Not that this only works if SystemNavigation always uses its environment and not the incoming class' environment. See:

Behavior >> #allCallsOn:
Object >> #systemNavigation

Since class references can be compared against method references, make it that method references can be compared against class references, too.

In text editors, [cmd]+[shift]+[N] now correctly includes references in pool dictionaries.

Adds support for class bindings to system navigation.

Not sure about "self environment" vs. "aClass environment" because tools will usually create a system navigation with the correct environment set.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at July 22, 2019 09:44 AM

For class-ref search, use the tool's environment to find the relevant class binding. Do not rely on the class's original environment.

This shouldn't make any difference at the moment but maybe in the future if somebody decides to make the identity of class bindings important. See:

Lookupkey >> #literalEqual:
ClassBinding >> #literalEqual:

Also see TextEditor >> #referencesToIt, which also uses the tool's (there: "model") environment.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at July 22, 2019 09:06 AM

Fixes regression in class-ref search to not yield methods that send only symbols of class names. For class symbols, use regular senders search with a symbol (i.e., #allCallsOn:).

Addition to Collections-mt.845.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at July 22, 2019 08:02 AM

During all-literals enumeration, do not decend into association values.

Users want to find the tokens they typed, not what the system generated or somehow stored. In particular, there is no need to look into class variables for literals. :-)

Replace the code duplication from xLetter which was the same as the step method.
This is done in order to allow customization of the step method without having to modify both places. All other methods already use the explicit step method.
"open code step for speed" no longer applies anyways as a method call is fast enough nowadays.

Fix fallback code for primPosixMicrosecondClockWithOffset: to not allow DateAndTime class>>now to create an instance with nil instance variables. Previous fallback code was a cut and paste error, never worked as intended.

Rationale for the fallback handling: Corrupt DateAndTime can quickly lead to a broken image. A default value of the Posix epoch is easily recognized as un uninitialized DateAndTime.

To test, evaluate "Time clockPolicy: #acceptPlatformTime" and comment out the primitive call in Time class>>primPosixMicrosecondClockWithOffset: to simulate the case of a VM that does not provide primitiveUtcWithOffset. In this case, DateAndTime now produces 1970-01-01T00:00:00+00:00. After testing, do Time initialze to restore clock policy.

1) Refactor #findTokens: to look like #lines (i.e. #linesDo: and #lineIndicesDo:).
2) Add #findFeaturesDo: like #findTokens:do: and #linesDo:.

Try this:

HTTPDownloadRequest name findFeatures.
(Morph >> #drawOn:) getSource asString findFeatures.

Where can that be useful?

- Automatic insertion of "*" for search terms like "WeakDictionary" to also find WeakIdentityDictionary etc.
- Prefix emphasis for names lists of classes in code browsers: MCAddition, MCAncestry, etc.

Clean up AbstractEvent:
- Make it more clear that "environment" is a dictionary local to system-change events.
- Remove #environment message to avoid mixup with Object >> #environment.
- Reduce the nunmber of inst-var references.
- Fix several message categories.
- Add missing #environmentKind to SystemChangeNotifier. For consistency. I have no clue why those re-directs exist. Maybe because "AbstractEvent classKind" is hard to read but "SystemChangeNotifier classKind" is not.

Use Url rather than deprecated URI in ProjectLauncher>>startUpAfterLogin.
This prevents command line startup scripts from failing due to a deprecation warning.
Also fix a comment typo.

Introduce settable parameters for tuning the Large Integer arithmetic thresholds.

Use these parameters in the accelerated arithmetic.

For Burnikel Ziegler, ensure at least two recursions by using twice the threshold of digitDiv21: before engaging a digitDivSplit: - this somehow mitigates the overhead cost of digitDivSplit:

Oups fix creeping of sqrt2, it was only for bench purpose.
Sorry for multiple commits.

I rely too much on (alt shift i) to ignore methods, but sometimes I miss one.
It would be cool to have a way to hide the ignored methods before committing.

Make sure that LargePositiveInteger sqrt are always correctly rounded to nearest Float if inexact.

Note that I accidentally introduced a rounding bug in LargePositiveInteger sqrt which was not in original Integer>>#sqrt:
(self bitAnd: 1) should have been (integerResult bitAnd: 1).
Apologizes.

But this formulation was subject to double-rounding error anyway (asFloat did perform a second rounding, which may lead to incorrect rounding), so that did not really matter...

Concerning performance, here are the bench results, after correcting the original version (I send twice self asFloat, which was a slip, and the original did not test mightBeASquare either when self asFloat = Float infinity)
- When (self mighBeASquare), new code is equivalent, and becomes more performant for huge values
This is due to sqrtRem which avoids evaluating a #squared for no additional price
Note that 7 large ints out of 256 mightBeASquare
- else it depends on bit range, new code is :
* as performant in range (SmallInteger maxVal highBit + 1 to: Float precision * 2)
that's the case of vast majority of large int in a "normal" image
* less performant in range (Float precision * 2 + 1 to: Float emax) by 3x to 5x
that's because asFloat sqrt is cheaper than sqrtRem
* more performant in range (Float emax + 1 to: infinity) by large
this is due to evaluating sqrtFloor on a much smaller LargePositiveInteger
(but this trick could have been added in inexact-rounding variant too)

So the exact rounding:
- does not require additional code (both are equivalent)
- does not cost any performance penalty in most common cases (small LargePositiveInteger); the penalty is only in medium range (107 to 1023 bits).

In a word, it's worth.

Second iteration of #take: (and #any:). #any: relates to #anyOne and thus signals an error if the collection is not large enough. #take: uses #any: but accounts for smaller collections.

Adds #take: to create a sub-collection from any collection by specifying the number of elements. Works like #first: for sequenceable collections but does not fail if collection is too small.
