1. [Download](http://fossil-scm.org/index.html/uv/download.html)
fossil if you do not already have it set up on your system. It is
distributed as a single file executable so installation consists of
simply placing it in some suitable directory in your `PATH` environment
variable.

1. Create a user account on the [TIP repository](https://core.tcl.tk/tips) if
you do not have one already.
You can create one yourself, but the administrator needs to
assign you commit privileges.

1. [Clone](http://fossil-scm.org/index.html/help?cmd=clone) the
repository into a suitable directory. For example,

        cd ~/repos
        fossil clone https://[email protected].tk/tips tips.fossil

1. Checkout the TIP sources into your working directory with the
fossil [`open`](http://fossil-scm.org/index.html/help?cmd=open) command.

        cd ~/tips
        fossil open ~/repos/tips.fossil

................................................................................
# Adding the new TIP

To add a new TIP,

1. Create a file in the `tip` subdirectory.  Choose a name of the
format `NNN.md`, for example 467.md. The TIP numbering is currently
not enforced by the system, so pick the next unused number based on
the [current TIPs](https://core.tcl.tk/tips/doc/trunk/index.md).

1. [TIP 2](https://core.tcl.tk/tips/doc/trunk/tip/2.md)
specifies guidelines for writing a TIP.
Write up the text, using [Markdown mark-up](/md_rules) (plenty of
examples are available - pay attention to the header as described below).
**NOTE:** if you already have the TIP text written in the old TIP format,
you can use the `tip2md.tcl` script in the `scripts` subdirectory
to convert it to Markdown.

................................................................................
	    Vote:           Done
	    Post-History:
	------

The meta-data is terminated by `------` and indented with tabs
(for nicer display in fossil).

See [TIP 3](https://core.tcl.tk/tips/doc/trunk/tip/3.md) for a detailed
specification of the header format and meaning of each header field.

This is a reasonable solution, because any encoding including the system
encoding may be used as shown in the upper example.

# Reference Implementation

See the _tip-106-impl_ branch in Tcl's fossil repository
<https://core.tcl.tk/tcl/timeline?r=tip-106-impl> .

# Rejected Alternatives

I proposed to use a switch ?**-encoding** _encoding_? which would
avoid the preparation of an encoded string by **encoding convertto**.
DDE is so little used at those days so a minimal support is sufficient.

Implementation of this TIP requires only changing a single default in
each of the platform specific _tk\*Default.h_ files, and updating the
documentation and test cases.

Note that this change was already done in Nov. 2004, on OS X only, by

<https://core.tcl.tk/tk/info/2cb92ba546de97e1>

Indeed on OS X menues cannot be torn off.

# Compatibility

Unfortunately, entries in menus are often accessed by index within
scripts, and the presence or absence of tearoff affects this index.

 TCL\_LINK\_BINARY: The address of the C variable is used as a _unsigned char
   *_. The address remains always the same. Read and write operations must
   always contain the full sized binary string.

# Reference Implementation

See [patch 1992842](https://sourceforge.net/support/tracker.php?aid=1992824).
See [`tip-312-new` branch](https://core.tcl.tk/tcl/timeline?r=tip-312-new).

# Notes

The original TIP proposed a _link_ command to allow these things to be done
from the script level; this has been removed in the test suite support because

 TCL\_LINK\_BINARY: The address of the C variable is used as a _unsigned char
   *_. The address remains always the same. Read and write operations must
   always contain the full sized binary string.

# Reference Implementation

See [patch 1992842](https://sourceforge.net/support/tracker.php?aid=1992824).
See [`tip-312-new` branch](https://core.tcl-lang.org/tcl/timeline?r=tip-312-new).

# Notes

The original TIP proposed a _link_ command to allow these things to be done
from the script level; this has been removed in the test suite support because
of concerns about safety and security.

The second case does imply a Potential Incompatibility, since currently SBFA is documented to always return TCL\_OK. However, it is felt
that virtually all cases that are sensitive to this, are actually half-working
in a completely hidden manner. Hence the global effect is a healthy one.

# Abstract

This TIP proposes mechanisms for inspecting the TclOO call chain for a
particular method, both externally via **info** and from within a call to
that method. It also proposes a mechanism that will allow the traversal of the
................................................................................
_arg_uments given, of course\). It will be an error to attempt to call a
class's implementation of a method that is not on the chain, or that is
preceding the currently executing method implementation, and it will not be
possible to jump to filters applied to the method.

# Reference Implementation

See <https://core.tcl.tk/tcloo/timeline?r=development-next2> for the proposed
implementation \(notably commit-f5a2cfd0d4\).

SourceForge staff have formally designated CVS hosting to be a legacy product
and offered assistance with migration to Subversion.

Since for some time the Tcl/Tk maintainers have wanted to transfer the version
control repository to a distributed version control system \(DVCS\), the
decision has been made to abandon SourceForge and adopt a Fossil repository. A
donor who wishes to remain anonymous has given a reasonably powerful machine,
**core.tcl.tk** to the Tcl Community Association and is providing rack space
and bandwidth. The donor has also generously offered to make free shell
accounts to qualified Tcl/Tk developers for CPU- and bandwidth-intensive tasks
such as performance analysis and memory management audits. Interested
developers should contact one of the TCT members listed at the end of this
document.

Needless to say, given the distributed nature of Fossil, we expect several
mirrors to emerge; Richard Hipp of SQLite.org has provided the first one,
appropriately named **mirror1.tcl.tk**.

# Repository Locations

The code base for Tcl itself now resides in a Fossil repository at
<http://core.tcl.tk/tcl/> .  The Fossil repository is available for anonymous
cloning and for examination of version control history.  At present, the bug
tracker is disabled.  Similarly, the code base for Tk resides at
<http://core.tcl.tk/tk> .  Tcl and Tk developers shall be granted 'push' rights
to the respective repositories.

Developers who are unfamiliar with Fossil are strongly encouraged to consult
the documentation at <http://fossil-scm.org/> , in particular, the 'Fossil
Concepts' paper at
<http://fossil-scm.org/index.html/doc/trunk/www/concepts.wiki> .  Novices to
Fossil may want to work at least temporarily in 'autosync mode', which allows
................................................................................
SourceForge. Any developer hosting a mirror is expected to disable the bug
tracker \(it suffices to remove 't' permission from the 'anonymous' user\). At
some point we may use a SourceForge-to-Fossil converter for the existing
trackers, and we do not wish to worry about trying to keep SourceForge and
Fossil in sync.

**mirror1.tcl.tk** shall be kept up to date by a periodic automatic
synchronization with **core.tcl.tk**.  In order to avoid inadvertent
forking, developers are requested not to push to mirrors unless
**core.tcl.tk** suffers an extended outage.

Before using a clone from a mirror, developers should verify that it copies
the correct version of the repository at **core.tcl.tk**.  This can be
determined by examining the 'project ID', reported by the 'clone'
operation. For Tcl, the ID should be

	    1ec9da4c469c29f4717e2a967fe6b916d9c8c06e

and for Tk, it should be

	    b5a34cc57b6712927bc5fd34ae98433a14c9fdea 

**UPDATE, June 2013** The ticket trackers have now also been migrated
from SourceForge to **core.tcl.tk**.

lists are still in use. On win32, mac and any reasonable recent X11 package,
this test passes.

Lars has mailed on tclcore that TclX has a command **cconcat** that does essentially what my proposed **string cat** is supposed to do \(not sure though whether that is compiled\). This proposal sticks to the **cat** subcommand, as that is generally the preferred way over new toplevel commands.

Also, **string concat** is added to this section, for it is a bit longer than **string cat**, and \(as Lars put it\) **string cat** is less likely to be misinterpreted as "concat, just moved into the string ensemble."

The proxy window \(i.e., the moving sash\) of the Tk paned window widget is hard
to see in some circumstances.  This TIP adds three options allowing more
control over the display of the proxy so that its visibility can be enhanced
where required.

# Rationale

As identified in [Bug: 1247115, <https://core.tcl.tk/tk/tktview/1247115],> a
flat sashrelief is common for **panedwindow** widgets, when it separates two
widgets with sunken relief.  For example, the left part can be a tree and the
right part a text widget, both with a white background.  Under Windows, the
paned window has a light grey color, and in this configuration, the proxy
window is not well visible when it is moved over its managed widgets.

# Proposed Change

solved by adding a modifier **-update** allowing the user to be sure any
possible out of date line height information is recalculated.

It appears that aside of **.text count -ypixels** there are several other
cases where wrong results can be produced by text widget commands. These cases
are illustrated in several bug reports:

 * <http://core.tcl.tk/tk/tktview/1566949>   \(.text yview moveto\)

 * <http://core.tcl.tk/tk/tktview/e51941c>   \(.text yview\)

In all these cases, forcing the update by calling **.text count -update
-ypixels 1.0 end** before calling **.text yview**, or **.text yview
moveto** solves the issue presented in the ticket. This has however a
performance cost, of course, but the above tickets show that there are cases
where the programmer needs accurate results, be it at the cost of the time
needed to get the line heights calculations up-to-date.

with version 8.7. Still it would be desirable for the TCT to describe a
procedure for that, this is outside the scope of this TIP.

made deprecated in some earlier minor Tcl 8.x release.

 * RFE 1754048 <https://core.tcl.tk/tk/tktview/1754048> 

# Proposed Change

It is proposed to add the following tag configuration options to the Tk
**text** widget:

**-selectbackground** _color_:
................................................................................
   indented by **-rmargin**. It may have any of the forms accepted by
   **Tk\_GetColor**. If _color_ has not been specified, or if it is
   specified as an empty string, then the color specified by the
   **-background** widget option is used.

# Rejected additional tag configuration options

RFE 1759972 <https://core.tcl.tk/tk/tktview/1759972>  requested stippling
\(**-selectbgstipple**, **-selectfgstipple**\) for selected text. Also RFE 1754048 <https://core.tcl.tk/tk/tktview/1754048>  requested stippling in left and right margins of the text widget \(**-lmargin1stipple**, **-lmargin2stipple**, **rmarginstipple**\).

Any new stippling options was rejected during the discussion about this
TIP. Reasons were as follows:

 * "Stippling and anything related to Tk Bitmaps should be considered
   obsolete. Their use should be phased out, not expanded. \(Bitmaps have
   very limited support in Tk, and stippling is virtually never used in

RFE 1759972 <https://core.tcl-lang.org/tk/tktview/1759972>  requested stippling
\(**-selectbgstipple**, **-selectfgstipple**\) for selected text. Also RFE 1754048 <https://core.tcl-lang.org/tk/tktview/1754048>  requested stippling in left and right margins of the text widget \(**-lmargin1stipple**, **-lmargin2stipple**, **rmarginstipple**\).

Any new stippling options was rejected during the discussion about this
TIP. Reasons were as follows:

 * "Stippling and anything related to Tk Bitmaps should be considered
   obsolete. Their use should be phased out, not expanded. \(Bitmaps have
   very limited support in Tk, and stippling is virtually never used in

add** command. The **count** argument represents weekdays \(Mon-Fri\) to be
added \(or subtracted in case of a negative value\) to the date. The result of
adding weekdays to a date is never a weekend day, unless the starting day is
itself a weekend day and **count** is 0.

# Reference Implementation

Available at <http://core.tcl.tk/tcl/timeline?t=tip-444>

# Discussion

A point has been raised as to whether _weekday_ is unambiguous enough. For instance, in Sweden there seems to be some disagreement on whether the translation _vardag_ includes Saturdays. As an alternative, the term _workday_ has been mentioned. This, however, has the downside of introducing the concept of working days vs. public holiday. Also, the working week is not Mon-Fri in all countries, see <https://en.wikipedia.org/wiki/Workweek_and_weekend#Around_the_world> .

TIP does not try to accomodate locale-specific features and characteristics. For this reason, it seems best to stick to _weekday_ as the name of the unit and specifically mention that \(Mon-Fri\) is intended in the documentation.

A **frame** keeping a size without reason just feels like a bug and mostly leads to unwanted results.

Mostly, it looks just ugly, but there are critical use-cases, specially in scrolled frames.

When the BWidget autoscroll package is used, which displays scrollbars on demand, the scrollbars do not disappear if the contents is gone.
And there is nothing, a programmer can do, as the Configure event does not fire on the scrolled frame widget.

Another example is the scrolledwindow example by Emiliano in ticket 2863003fff <https://core.tcl.tk/tk/info/12006979562649c9> , where the solution 2 specific part may be removed \(or is ignored\).

A typical workaround is to configure the width/height manually after the last children was unmapped.
Unfortunately, this fact may not be determined for example by scrolling widgets etc. An eventual Configure binding is not firing.

# Example

Here is an example to ilustrate the issue.
................................................................................
	bind .c.f <Configure> frameConfigure

# Proposal

The proposal is to change request size of the frame automatically to 1x1 if the last children is unpacked/ungridded/destroyed.

Koen Dankart has passed a patch for this solution containing 3 additional lines of C code.
It is available in branch bug-d6b95ce492-alt: <http://core.tcl.tk/tk/timeline?r=bug-d6b95ce492-alt&nd&c=2016-09-22+09%3A16%3A21&n=200> .

It just solves the issue by restoring initial size if the last children is unpacked/ungridded.

This is not backward compatible.
But that is a side effect of fixing this bug.

# Rejected Proposal

Another proposal is to invoke the virtual event \<\<GeometryManager\>\> when the last children is unpacked/ungridded/destroyed.

Emiliano has provided a ticket 2863003fff <https://core.tcl.tk/tk/info/2863003fff>  with the implementation in branch bug-d6b95ce492 <https://core.tcl.tk/tk/timeline?r=bug-d6b95ce492&nd&c=2016-09-21+06%3A32%3A55&n=200> :

The virtual event **\<\<GeometryManager\>\>** is defined which informs the master \(a frame-like widget\) that it has no child widget any more and that its size is not managed any more by grid/pack.

The program may bind to this event and resize to size 1x1:

	   bind .c <<GeometryManager>> "resizeFrame %W"
	   proc resizeFrame w {
................................................................................
Due to those issues, the TIP is withdrawn.
A way to solve the issue in a compatible and working way is to use Emilianos additional virtual event, as described in the section 'rejected alternatives'.

   *   Discussion on the core list <http://code.activestate.com/lists/tcl-core/16363/> 

# Compatibility

Fixing the issue breaks visual compatibility.  Nevertheless, as it is seen as a bug, this is OK.

Support of versions back to 8.5 is currently included in the revised code, but
will be removed \(because it's useless for use in trunk only\) at the time the
new code will get merged into trunk.

# Implementation

Implementation of the revised text widget code has been placed in branch
<http://core.tcl.tk/tk/timeline?r=revised_text>  of the fossil repository.

This implementation compiles on Linux, Windows, and OS X. It respects the
standards of Tk \(C99 standard, and also the Tcl source code formatting
described in [[247]](247.md)\).

The man page for the text widget has been contributed by jima and is included
in the revised\_text branch.

formats without any need for the community to maintain the converters, and
supports key extra features such as embedded images \(which are important for
some Tk TIPs, and never worked particularly well with the old TIP format\).

# Specification

Proposed URL for the new repository will be <http://core.tcl.tk/tips>

## Backwards compatibility

 * _tip.tcl.tk/<NUM>.html_ should still show a rendered result. This could be redirected to _core.tcl.tk/tips/doc/trunk/tip/<NUM>.md_

 * _tip.tcl.tk_ offers several converted formats \(XML, \*roff, ...\). The fossil option will be to use the _core.tcl.tk/tips/file/tip/<NUM>.md?download_ URL to get the raw Markdown downloads. For getting the other options one could convert the markdown source file using something like pandoc.

 * E-mail address are not hidden in the source and in the rendered result.  If e-mail addresses need to be hidden there are two options

    1. Remove mails from source.

    2. Hide e-mails in fossil.

That is ugly, and won't even work reliably for getting the context object in
**oo::objdefine** as that can be entered into by multiple paths \(i.e.,
there's a shortcut from **oo::define**\).

namespaces as the basis for objects\). It was requested by Nathan Coulter as a
way to enable more complex behaviour in Rivet and NaviServer. See Tcl Issue

index formats.  Thus it is reasonable to provide a standard substring insertion
command.

The current design of [`string replace`] expressly (albeit inexplicably)
prevents its use for performing string insertion.  TIP 323 originally proposed
to extend [`string replace`] to allow string insertion, but this aspect of TIP
323 was [withdrawn]
(https://core.tcl.tk/tips/fdiff?v1=6e0ba0ee9838accc&v2=34809f1432fc528f&sbs=1)
for the sake of compatibility.

The desirability of providing C APIs is made clear by the existence of the the
[FlightAware [`array`] enumeration C API project]
(http://core.tcl.tk/tcl/timeline?t=amg-array-enum-c-api).

# Current Behavior

Currently available methods for string insertion are awkward and do not handle
end-relative and [TIP 176-style](176.md) indexing without extraordinary effort.
To demonstrate the surprising degree of complexity, the following is a pure Tcl
script reference implementation intended to handle all possible index formats
................................................................................
replace`] commands in terms of `Tcl_ReplaceObj`().

# Reference Implementation

A pure Tcl reference implementation is given [above](#ref).

The [`amg-string-insert`]
(http://core.tcl.tk/tcl/timeline?t=amg-string-insert) branch in the Tcl Fossil
repository provides an optimized C implementation, complete with documentation,
bytecode compilation, and a full set of test cases exercising all code paths.

This C implementation creates a new `strinsert` bytecode, also known as
`STR_INSERT` or `INST_STR_INSERT` in varying contexts.  The decision was made to
keep `strinsert` separate from the existing `strreplace` opcode due to
differences in end-relative indexing.

Implementing [`string insert`] in terms of `strreplace` would require modifying
the interface to `strreplace` and would therefore break compatibility with
[tclquadcode] (https://core.tcl.tk/tclquadcode/) and potentially other projects
that depend on the \[[`tcl::unsupported::assemble`](http://wiki.tcl.tk/28070)]
and \[[`tcl::unsupported::disassemble`](http://wiki.tcl.tk/21445)] commands.

Despite the use of the word "separate" above, the `strinsert` and `strreplace`
opcodes are both implemented in terms of the common `Tcl_ReplaceObj`() function,
as are the non-bytecoded [`string insert`] and [`string replace`] commands.
This function was written by distilling common code found across the baseline
implementations of the various subroutines that now call it.

# Open Issues

The `Tcl_ReplaceObj`() function header comment includes [this TODO note]
(https://core.tcl.tk/tcl/artifact?name=6934c9ea66d17949&ln=3312-3315):

> Memory allocation failure is only checked when concatenating shared, non-pure

This comment is describing the [case]
(https://core.tcl.tk/tcl/artifact?name=6934c9ea66d17949&ln=3575-3592) in which
`Tcl_ReplaceObj`() calls `TclStringCatObjv`() to concatenate its two arguments.
`TclStringCatObjv`() returns TCL_ERROR on memory allocation failure, and
`Tcl_ReplaceObj`() dutifully translates that to a NULL return, with detailed
error information in the interpreter result.

In every other circumstance, `Tcl_ReplaceObj`() does *not* check for memory
allocation errors.  Many, if not all, of the underlying functions it uses call

# Abstract

The "case" command, and the "read\|puts ... nonewline" construct are replaced
by better commands long ago (resp. "switch" and "read\|puts -nonewline ..."),
but the old forms were never actually removed from the Tcl code base. They still
work. See also [bug #3151675](https://core.tcl.tk/tcl/tktview/3151675).
For Tcl 9.0 it is finally time to actually remove it.

In addition, there are a number of C API's which have better successors
by now. Finally, there are a few C routines and other macros which were
never been properly documented before, like `CONST`, or macros needed for
supporting deprecated C features, like `_ANSI_ARGS_` and `TCL_VARARGS`.
This TIP proposes to finally remove all of those in Tcl 9.0, and mark

 * `Tcl_CreateMathFunc`

 * `Tcl_GetMathFuncInfo`

 * `Tcl_ListMathFuncs`

An implementation of this TIP can be found in the [tip-485](https://core.tcl.tk/tcl/timeline?r=tip-485) branch.
This branch is based on "core-8-branch" (Tcl 8.7), but can be trivially merged forward to trunk (Tcl 9.0).

# Rejected Alternatives

Originally, `Tcl_EvalFile` was a candidate for removal as well.

Originally, XP-support was suggested to be removed as well, but it turns out
that it's too early to do that now and gives too little benefit. Since XP
seems to be even more popular than Vista, support drop for both of those could
be done at the same time in a future Tcl/Tk release. But that decision will
be left up to another TIP.

# Abstract

This TIP provides user access to the busy window that Tk uses to let a user think a widget is busy.

# Rationale

The tk::busy documentation describes how a busy window is created to block events. The path of this busy window can be used to handle some events. This path is dependent on whether the widget to be covered is a toplevel or not, see [implementation details here] (http://core.tcl.tk/tk/artifact/3a2775faf288a7c9?ln=535,556) and also the man page for **tk busy**.

As a consequence, this logic needs to be known by any user of the **tk busy** command. Offering  a way to get the path of the busy window would avoid this dependency on the implementation details.

# Proposal

It is proposed to:

................................................................................
2. Provide a new subcommand **tk busy busywindow** to return that same information, or the empty string if the windows passed to it is currently not busy.
3. Remove any mention of the details of the busy window naming from the man page.

  * Tcl_Ungets

If the return value of such function is directly used in a compare, this could lead to the use of an unsigned compare in stead of a signed compare.
If you compile your extension with -D_TCL\_8\_COMPAT_, those 10 functions will be changed to wrapper macro's which makes everything behave as if those functions return Tcl_WideInt. That's the easiest way to resolve this potential problem.

There are 2 other ways to make this change, which can do it without the use of the _TCL\_8\_COMPAT_ macro:

  * Add _1_ to the left and right hand side of the comparison. E.g. [as here](https://core.tcl.tk/tk/fdiff?v1=100235897e9cf359&v2=9cf86629040df0d3)

  * Don't compare to -1 using < or >, but always to TCL\_IO\_FAILURE using == or != . E.g. [as here](https://core.tcl.tk/tk/info/abe0d3b121cbb12d)

Tk and [sqlite](http://cyqlite.sourceforge.net/cgi-bin/sqlite/info/17c148b94008df81) are already converted to make full use of TIP #494. Other extensions included with Tcl (e.g. tdbc) are unaffected.

# Open issues

There has been discussion, whether the return-type of these 10 functions (and possibly other functions) should actually be size\_t or maybe some other type.
A Tcl-specific type *Tcl\_Size* could also be defined for this. Actually, this TIP provides 2 possibilities: Without -D_TCL\_8\_COMPAT_, the type is size\_t, with -D_TCL\_8\_COMPAT_ it is Tcl_WideInt.
................................................................................
There - for sure - will be more future TIP's, which propose more API changes for 9.0.
This one - definitely - is not the last one.
So, this TIP doesn't make a final decision yet what will be the final type returned by those 10 functions.

created in it but they disappear at some later point depending on the state of
the call stack.  Although this behaviour is documented, it was probably a
concession to the implementation rather than by original intent.  A further
complication is that it's possible to simultaneously access both the deleted
namespace and a new namespace having the same name.  Reports that illustrate
these issues include:

> [A namespace loses track of itself](https://core.tcl.tk/tcl/tktview?name=46450b464e)

> [command found in deleted namespace](https://core.tcl.tk/tcl/tktview?name=1655294fff)

> [namespace deletion: trace that calls [apply], specifying the namespace, doesn't fire.](https://core.tcl.tk/tcl/tktview/e86e178aff)

Finally, the current cleanup routines perform enough contortions to be a real
barrier to any further improvement of the system.  

The work to [simplify the TclOO
implementation](https://core.tcl.tk/tcl/info/0bae33cd39c2333e), lead to the
work to simplify Tcl_DeleteNamespace.

There are various reports about traces that that silently fail under one
condtition or another.  The simplification of `Tcl_DeleteNamespace` is a
precursor to the resolution of those issues.


................................................................................
easier to discover that the current namespace is the global namespace than it
is to determine why a namespace which exists at one point no longer exists at
another point, even though there is no point in between at which the namespace
is deleted.

The completion of this TIP will render more tractable the issue [trace deletes the namespace
when a command is replaced, producing "called Tcl_CreateHashEntry on deleted
table"](https://core.tcl.tk/tcl/info/0e4d88b650).

`activationCount` is removed from the `Namespace` structure, slightly reducing
its size.  See also, [Improve average size of
Namespace](https://core.tcl.tk/tcl/tktview?name=2694630fff).

`NS_KILLED` will no longer be needed.  A namespace being deleted is either
`NS_DYING` while deallocation of related resources is in progress or `NS_DEAD`
while it's still referenced somewhere.

The issue [(tailcall\|yieldto) failed to find the proper namespace
Abort](https://core.tcl.tk/tcl/tktview?name=3592747fff) becomes more
straightforward to reason about since there are no longer namespaces that
exist but that are not reachable by name.

It will be documented that when a namespace is deleted, ensemble commands,
child namespaces, commands in the namespace, and variables in the namespace are
deleted in that order.  Because the deletion of a resource can trigger the
creation of other resources, this process iterates until all relevant resources

- The included nanosvg header files will be remain diffable to the original ones. So changes in the original project can be ported to our implementation.
- The format options will be limited to a minimum. So the implementation can later be substituted with a full [SVG][] compatible one.
- If the implamenation will be replaced it will occur in a different tk version. So there is no need to create a scpecial variable describing the used [SVG][] implementation.
- To further reduce the interface it is possible to remove the **-dpi** and **-unit** options. There is currently no demand for this.

# Implementation

A patch implementing these changes is available in the fossil repository in the [tip-507 branch](https://core.tcl.tk/tk/timeline?r=tip-507).

The new format is described in the photo(n) man page.

- The included nanosvg header files will be remain diffable to the original ones. So changes in the original project can be ported to our implementation.
- The format options will be limited to a minimum. So the implementation can later be substituted with a full [SVG][] compatible one.

- Multiplatform code in its current form behaves either inconsistently or
  consistently, depending on whether it uses reentrant mutexes or not.
  Consistent code will remain consistent, inconsistent code will become
  consistent as the Unix version aligns with the Windows version.

# Related Bugs

[Bug #f4f44174](https://core.tcl.tk/tcl/tktview/f4f44174) demonstrates the
deadlock issue with a script based on TclX. The root cause is the asynchronous
event handler's `Tcl_Mutex` being locked twice from the same thread when a
signal handler interrupts a thread in the middle of a mutex-protected section,
which on Unix platforms results in a deadlock. The proposed implementation fixes
this issue.

New oo::class like widgets **tko::frame**, **tko::labelframe** and **tko::toplevel**

> The new widgets will contain the same functionalite like the original *tk* widgets. They are *oo:class*'s and it is possible to add,change and delte methods and options dynamically. The widgets could also be used as oo *superclass*'s.

New **tko::widget** oo base class for widgets.

> The class provide the extended cget/configure tcl methods (see [`tkoWidget.n.md`](https://core.tcl.tk/tk/doc/tip-510/doc/tkoWidget.n.md)) and a C interface (see [`tkoWidget.3.md`](https://core.tcl.tk/tk/doc/tip-510/doc/tkoWidget.3.md)) to build new widgets.

# Rationale

## Rbc commands

*Tk* has already adopted some of [BLT][]/[Rbc][] commands.
Still missing are the above mentioned commands.
................................................................................
Currently there is no megawidget support core package. These tip will go some steps in this direction. With widgets as **oo::class**'s we can easyly extent existing widgets, just use it as a superclass. The provided cget/configure methods allow add, delete and changing of options. The implementation can be used in C and in Tcl.

The new widgets **graph** and **path** are also implemented as **oo::class**. This will make it easy to extent the functionality. As an example see the file `.../library/graph.tcl` in which the method **binding** of the **graph** widget is implemented.

# Implementation

A patch implementing these changes is available in the fossil
repository in the [tip-510 branch](https://core.tcl.tk/tk/timeline?r=tip-510).

# Discussion

See also discussion at the [wiki](http://wiki.tcl.tk/55360).

A first voting was rejected, mostly because of the missing Mac implementation. See:

................................................................................

<http://code.activestate.com/lists/tcl-core/20384/>  

# Open issues

- Mac implementation of **graph** widget. May be borrow code from **path**
- Remove or change old code in `generic/tko/*` files <http://code.activestate.com/lists/tcl-core/20384/>
- Hardcoded usage of compiler and libraries in [`win/Makefile.in`](https://core.tcl.tk/tk/doc/tip-510/win/Makefile.in), [`win/makefile.vc`](https://core.tcl.tk/tk/doc/tip-510/win/makefile.vc) and [`unix/Makefile.in`](https://core.tcl.tk/tk/doc/tip-510/unix/Makefile.in) (search for "#RZ TODO").
- Add **path** files in Mac implementation. It works at least in [Androwish][].
- Which platforms should be used in **path**
  - SDL/AGG: platform independent, more work is needed using [`tkoPath_SDLAGG.cpp`](https://core.tcl.tk/tk/doc/tip-510/generic/tko/tkoPath_SDLAGG.cpp). See in [Androwish][]
  - GDI+ on Windows => working with [`tkoPath_WinGDIPlus.cpp`](https://core.tcl.tk/tk/doc/tip-510/generic/tko/tkoPath_WinGDIPlus.cpp)
  - Cairo on unix => working with [`tkoPath_UnixCairo.c`](https://core.tcl.tk/tk/doc/tip-510/generic/tko/tkoPath_UnixCairo.c)
  - For Mac see [`tkoPath_MacOSX.c`](https://core.tcl.tk/tk/doc/tip-510/generic/tko/tkoPath_MacOSX.c)
- Provide demos
- Add more **path** tests
- Is it necessary to translate the documentation into man format?
- It is currently not possible to use unique abbreviations of class method names p.e. "graph .g; .g conf" A workaround would be to add all those method names. May be this can be solved in tcl::oo directly?

Any help especially with the Mac implementation would be great!

This TIP proposes to remove the stub entries for `Tcl_SetExitProc()`,
`Tcl_SetPanicProc()`, `Tcl_FindExecutable()` and (for Tk) `Tk_MainEx()`.
The normal exported symbols for those functions will be kept intact.

# Context

This TIP is inspired by Tcl commit ["Add custom exit procedure for
tcltests executable"](http://core.tcl.tk/tcl/info/6f650b4271a1ef2e).
This commit demonstrates exactly what's the problem when using
`Tcl_SetExitProc()` in a stub-enabled extension: On win32 this
caused a crash in many unit-tests, when tclsh ended. This problematic
commit was corrected in [this commit](http://core.tcl.tk/tcl/info/df825488e649e15b):
a thread exit handler is how this should have been done. 

# Rationale

When running test-cases in Windows (using mingw-64 or MSVC, but using the
win/Makefile system not the nmake system), the `tclsh` executable
crashes after shutdown in some tests. The reason for this is that
................................................................................
Starting with Tcl 9.0, those stub entries will be removed completely.
In stead, those functions will be defined in tcl.h, as normal
exported symbols, just like `Tcl_MainEx()` (for example).

# Implementation

Currently, the proposed implementation is available in [tip-512 branch]
(https://core.tcl.tk/tcl/timeline?r=tip-512).

 * If you still really want to protect some command argument from overflowing, Use Tcl\_GetWideIntFromObj() in this command, and use "string is wide" to check for proper range.
   But - still better - is use Tcl\_GetWideIntFromObj(), while falling back to Tcl\_GetBignumFromObj() if the range requires it.
   That's what Tcl itself is doing almost everywhere to prevent under/overflow errors.

# Implementation

Currently, the proposed implementation is available in the [tip-514 branch]
(https://core.tcl.tk/tcl/timeline?r=tip-514).

For backwards compatibility reasons, this new option will have its defaults such that the rendering is unchanged compared to the current state of affairs, i.e. it will be **raised** on Linux, and **flat** on other platforms.

This new option will be accepted on all platforms, however on macOS it will be silently ignored since the native menues are used on this platform (***TkpDrawMenuEntry*** is an empty procedure on macOS).

# Implementation

An implementation of this TIP can be found in the [tip-517 branch]
(https://core.tcl.tk/tk/timeline?r=tip-517).

# Alternatives

Alternatively, instead of adding a new **-activerelief** menu option, the issue raised in [bug 43b596451e] (https://core.tcl-lang.org/tk/tktview/43b596451ec6b59359145ff32e689a2eec70bb85) could be resolved by changing the rendering of the active entry in Linux menues to become **TK\_RELIEF\_FLAT**, and keep the current **TK\_RELIEF\_RAISED** only if **tk\_strictMotif** is set. The drawback is that this would constitute a backwards incompatible change - However in turn this could be deemed acceptable in the current alpha state of 8.7.

An implementation for this alternate proposal can be found in [branch tip-517-alt] (https://core.tcl.tk/tk/timeline?r=tip-517-alt).

Having balanced the pros and cons between the two approaches, I'd prefer to add **-activerelief**, which in addition to be a backwards compatible change, has the merit of introducing additional configuration flexibility.

A **frame** keeping a size without reason just feels like a bug and mostly leads to unwanted results.

Mostly, it looks just ugly, but there are critical use-cases, specially in scrolled frames.

When the BWidget autoscroll package is used, which displays scrollbars on demand, the scrollbars do not disappear if the contents is gone.
And there is nothing, a programmer can do, as the Configure event does not fire on the scrolled frame widget.

Another example is the scrolledwindow example by Emiliano in [ticket 2863003fff](https://core.tcl.tk/tk/info/12006979562649c9), where the solution 2 specific part may be removed \(or is ignored\).

A typical workaround is to configure the width/height manually after the last children was unmapped.
Unfortunately, this fact may not be determined for example by scrolling widgets etc. An eventual Configure binding is not firing.

Within this TIP, a new virtual event `<<NoManagedChild>>` is fired to inform about no remaining childs.

# Example
................................................................................
	    .c.f configure -height 1
	    .c.f configure -height 0
        }
	bind .c.f <<NoManagedChild>> frameNoChild

# Reference Implementation

Emiliano has provided a [ticket 2863003fff](https://core.tcl.tk/tk/info/2863003fff) with the implementation in [branch bug-d6b95ce492](https://core.tcl.tk/tk/timeline?r=bug-d6b95ce492&nd&c=2016-09-21+06%3A32%3A55&n=200).

This solution is now continued with the tag "tip518-event-last-child-unmanaged".

Koen Dankart and François Vogel have worked on the solution of the similar tip474, which is available in [branch tip-454](http://core.tcl.tk/tk/timeline?n=100&r=tip-454).
This information may eventually also be relevant.

# Rejected Proposal

[TIP 454](454.md) has proposed to set the size of the widget automatically to 1x1 (the initial size if no widget packed/gridded).

Please read the discussion within the TIP which led to withdraw the proposal.

	} 5000

### Impact

As the current implementation in [sebres-8-6-timerate](/tcl/timeline?n=100&r=sebres-8-6-timerate) 
(or, for Tcl 8.5, [sebres-8-5-timerate](/tcl/timeline?n=100&r=sebres-8-5-timerate)) shows, no public API's are affected by introducing this,
A few new functions are provided for Tcl's internal API (see `tclInt.h`).

Don Porter (`dgp`) has made a review of the version of this change that  targets Tcl 8.7, which can be found in branch [dgp-sebres-timerate-review](/tcl/timeline?n=100&r=dgp-sebres-timerate-review).
The branch already contains the performance testing  framework as well as a new script, `tests-perf/clock.perf.tcl` that instruments the `clock` command in preparation for integrating changes that improve its performance..

<hr/>
## II. Proposed performance-testing framework: `::tclTestPerf`

The small test suite in the `::tclTestPerf` namespace allows for batch-based measurement and diff-based results
to compare performamnce among revisions and detect performance regressions.
