…he sample prints its code point (reported by launcher-re 21)
…e it Experimental; back under Contributed Packages and in the book; 17 new overflow cases (silent overflow in subtraction, squaring, the modular operations, ValueOctal/ValueBinary and products near the limit; a remainder near the limit does not return); the negative-shift case accepts error 5 or a right shift (owner)
…ibrary's capacity (corrupt quotient, hang), until a second agent confirms it
…shoot_docs setups (building*), the shot fixtures, and the console's thumb pinned so a rerun is unchanged
…win, Json module renamed JsonMember, so tblaunch can compile the other modules under its own Sub Main; WIP.md says so
… in Program.twin, what differs from tblaunch in BrokerHost, so tblaunch can compile the rest unchanged; WIP.md says so; broker.test 14/14, command lines and status the same as before
…would hide VBA's Command in every project that compiles it; broker.test 14/14, command lines the same
…SCII case only, as impexp.mjs and the twinBASIC edition do, and UTF-8 to a pipe; check_impexp_parity gains the two commands that catch each
…ource gives (the disk, or tblaunch's own files) as import does, which tblaunch's Pack now calls; ToCrlf copies runs, SortOrdinal is a merge sort, ByteBuilder.Reserve does not overflow (import of the VB package 146 ms to 72 ms, same bytes); the packer folds names as Node does (U+212A in Packages); parity 23/23 with IMPEXP_EXE, --self-test 20/20
…s project after project through the page's own path (about 2 s on BETA 1010); root.loadProject over CDP is what hangs it
…d project), not a hang, on BETA 1010
…st, keeps a wake that came while it read a sample, and re-polls at 50 ms while the page catches up: the 1 Hz tail (0.94 s median) becomes the 300 ms quiet
…the same compile, so a wait no longer stands still 5 s when the pair's one set of diagnostics beats id 1 (break-into's restart wait 6.05 s to 1.1 s)
…rmat$, &, Debug.Print), where a 32-bit build and VB6 give "0"; reproducer with eleven test cases and a VB6 side; WARNING on CStr, Str and Format (BETA 1010)
…ge has errors of its own: the panel rows of files the wire does not report on (unlistedRows) are added to the wire's counts, and the sample must stand unchanged for the 300 ms quiet; WinReg ends 0.3 s after its compile, not after the 5 s stand-still
…he compiler's start-up, now that the early path agrees for a package with errors of its own
…ion, tb-session.mjs: the page's openProject with the file dialog answered in the page; Safe Mode and TRACE-MODE reset before each switch; a failed switch, exit 2 or 3 starts a new IDE), --fresh for one IDE per project, and a batch that meets its limit is a finding, not the end of the run
…nd sweep_attributes mark it with .keep from the start (keepRunFolder), and the sweep of ended runs' folders (sweepRunFolders, tb-registry.mjs) leaves a marked one; a probe in example-batches covers it
…ore, and met twice its batch is not judged: since a batch that meets its limit no longer ends the run, the empty read was taken for a clean template, and a shared --fresh run blamed 17 ArrayListLib samples for the package's own TB5001 rows; two probes
…s its template's compile outruns the 10 s limit, so examples.bat could never judge them (owner); marked again when a version of WinReg compiles
…e or one equals the file, capturing on further apart for 5.5 s only within a pixel's wobble of the file; the settings setups open their project with the templates' build path, so llvmdoc1 no longer meets the user name
…aptured on for up to 5.5 s until the file shows, keeping the last two that agreed (a raster's other versions, a state still settling); the community badge clears the console's restart line itself
… as the host tells it, whatever the user's IDE window was; Rename_Box opens the box from the row's menu, since F2's key release turns the box red now and then; Controls_MultiSelect waits for the pointer readout, and e2a65dfe for every member's type
- The SVG of a picture whose PNG is not rewritten stays as it is, with its bundle: hidden layers differ from run to run, and an SVG on the bar came and went. - Controls_MultiSelect moves the pointer onto Check1 after the clicks, so that its readout shows in Light too. - Unsteady regions (owner): About's and the splash's two "See your logo here!" boxes (their gradient is dithered differently from capture to capture); the GitHub release's zip time; the splash's four rounded corners; a ring round each TabIndex circle of Designer_TabIndex, whose shadow over the grid comes out in one of two versions (formStateShot takes more unsteady regions). - peRename waits for the F2 box to hold the name with its base name selected before typing: a rename typed early left naifrmA.tbform. - Global search: once a search settles, every row of the results list is measured again (notifyChangedItem), since the list keeps a row's first height and a thumb showed over two results that fit. - e2a65dfe: the IDE places the completion list at the text cursor as drawn, at the dot or now and then after it; the shot moves the list to where the cursor stood at the dot. - Programs: tb-launch.ps1 can make a window on a private desktop the active one (activateWindow) and a capture says whether its caption is active; the program shots make the form active, and again when a capture finds its caption inactive.
…rived classes Classes-and-Modules compares the two constructors (arguments, VB6/VBA, COM clients, As New, calling them from code) and says when to use each, with a sample of a class that has both. Inheritance gains Constructors in Derived Classes: which base constructor runs, what a derived class's author does for each kind of base, why a Base.New call goes first and on every path, and the Class_Terminate order. Each page has a check_run sample, and the behaviour was probed on BETA 1010, COM creation through a compiled ActiveX DLL from VBScript.
Inheritance: automatic base constructor calls chain through every level; every class's field initializers run before any constructor, so a base constructor's Overridable call sees the derived fields set; a derived class can be declared As New, and Class_Initialize beside Sub New() fails with TB5073 there too; COM creation of a derived class runs the same constructors. Inline-Initialization: a Dim in a procedure can call anything, while a Static, module-level or class-field initializer cannot call a procedure of the project (TB5079/TB5027); which variables such an initializer can read; a field that reads another field of its class fails the build. Classes-and-Modules' ReadOnly paragraph no longer says any function can set a field inline. Probed on BETA 1010 with tbrun, tbrun --exe and a compiled ActiveX DLL created from VBScript.
…module initializers in the IDE
class-field-init-reads-field: a class field initializer that reads another
field of its class compiles, then fails the build with a codegen error in
'<Class>.{fields_init}'; an IDE run leaves an arbitrary value. Reproducer
mode build.
module-init-reads-other-module-ide: one module-level initializer that reads
another module's variable leaves every module-level variable at 0 in the
IDE ([RunAfterBuild]); the exe is right. Reproducer mode run.
Both verified on BETA 1010 with bug_repro.mjs verify. Inline-Initialization
names them in an HTML comment.
Before the comparison table, a sentence says Class_Initialize is inherited from VB6 and VBA and follows COM's rule that an object is created without arguments, and that Sub New is twinBASIC's addition. Suggested by a reader on Discord.
