[TCLCORE] Atomicity in Tcl and Tk

[Marc C. <cul...@gm...>]

I have a question for the experts.  It has to do with when the interpreter,
during execution of a script, allows idle tasks and timer tasks to be run.

There is an expectation in may situations that idle tasks will not be run
between two consecutive commands in the script.  For example, in
macosx/README it says:

The TkAqua-specific command [tk::unsupported::MacWindowStyle style] is used
to
get and set macOS-specific toplevel window class and attributes. Note that
the window class and many attributes have to be set before the window is
first
mapped for the change to have any effect.

That means that the following code is expected to work:
  toplevel .t
  tk::unsupported::MacWindowStyle style .t modal

but something like this:

  toplevel .t
  < lots of code here>
  tk::unsupported::MacWindowStyle modal

will probably not work because the window will get mapped during the <lots
of code>.  The window actually gets mapped in an idle task that is created
by the toplevel command.  The first code block works because that idle task
gets run after the MacWindowStyle command has run.

My question is essentially "How large can the <lots of code> be and have
this still work?"  What are the rules?  When running a script, when does
the interpreter pause and "return to the event loop"?  Is there some way to
ensure that a given block of code will run completely before any additional
idle tasks get run?

[TCLCORE] Thanks for TCL/Tk 9.0.0 and next steps

[Harald O. <har...@el...>]

Dear TCL/Tk community,

thanks to Don and team for the great release of TCL/Tk9.0.0. This is 
awesome! We all need a breath after this 7 years process.

---

May I propose a meeting to discuss the next steps ?
What about Monday 28th of October 12:00 UTC for one hour?
Many regions will have stopped daytime saving time then.

My personal agenda is:
- what is the next version of TCL/Tk for:
   - non breaking bugfix style TIPs (like the two most recent ones)
     (10.1 ?)
   - innovative TIPs (10.1a0 ?)
   - breaking TIPs (11.0a0 ?)
- what are the possible innovations?
   - factor out the image command from Tk
   - list image formats

By the way, the conference 2025 may be in Italy...

Thank you for all,
Harald

Dear Ashok,

thanks for the great TIP. I only have a question about the concerned TCL 
version. IMHO, this should go into version 9.0.1, not 9.1.x.

Take care,

Re: [TCLCORE] Tip 430 First argument handling for Tclsh/Wish (install or detected zip)

[Torsten B. <be...@ty...>]

Hi,

you are right, this feature was never implemented. It should have been added to the "Amendment" section of that TIP but was overlooked. I'll add that right away. There are several mismatches between the TIP and the real implementation. The "Amendment" section is supposed to document these. If you look at the tclsh manual page (https://www.tcl-lang.org/man/tcl9.0/UserCmd/tclsh.html) you will not find that feature documented either. This manual page and the zipfs manual page are the definitive source for reading about the real implementation (unless we have overlooked yet another mismatch ...).

Regards, Torsten

[TCLCORE] Tip 430 First argument handling for Tclsh/Wish (install or detected zip)

[Julian N. <ju...@pr...>]

Tip 430 states

If the first argument to Tclsh or Wish is detected to be a zipfile, that 
file will be mounted as*ZIPFS_ROOT*//app/. 
If*ZIPFS_ROOT*//app/main.tcl/exists, that file is marked set the shell's 
startup script. If*ZIPFS_ROOT*//app/tcl_library/exists, it will be 
searched for/init.tcl/.

Is this still meant to be a feature?
I've been unable to verify on windows - it just seems to try to run it 
as a script, giving the error:
couldn't read file "some.zip": invalid or incomplete multibyte or wide 
character

(same if some.zip replaced with a tclsh that has an attached zip)

glancing at the tclZipfs.c code it looks like this feature is dependent 
on the SUPPORT_BUILTIN_ZIP_INSTALL flag -  are the 'install' argument 
and mounting of first argument if a zip supposed to be enabled/disabled 
as a single unit?
I couldn't test anyway due to compilation error with that flag 
(https://core.tcl-lang.org/tcl/tktview/c5825d3235)
As that ticket reports - the 'tclsh install mkimg ..' is suspect anyway

Perhaps 'tclsh install/loading first arg if zip' works on other 
platforms? Anyone tried it?

I feel the mount first argument as a zip is perhaps an unnecessary feature.
Without this magic, it is easy enough anyway to cat a small Tcl script 
to the beginning of a zip - along with a ctrl-z character - and then the 
script can mount/set auto_paths etc as desired.
e.g I have a small file named #z containing the binary <SUB> character 
and do:
cat kitheader.tcl #z test.zip > kitname.zipkit

This works fine.

This mount-first-arg-if-zip feature would seem to have potential to 
collide with that and I don't currently understand the benefit..
  unless it allows dropping into a standard tclsh repl if no main.tcl is 
present?
That would be nice.
(I can do this  if I use a main.tcl-hacked-tclsh with a  as per my 
earlier message regarding dropping into a standard repl - but although 
I've seen the request pop up from users over the years - I don't see any 
interest/comments from this list)


Cheers,
Julian

Re: [TCLCORE] Tcl 9.0.0 RELEASED

I can’t speak for the entire TCT either but I endorse what Kevin said: there are no plans to retire 8.6 and in fact there was a priority made on getting 8.6.15 out just before 9.0.  FWIW we kept 8.5 going long after it should have been retired, and it is likely that 8.* will be kept going for longer.

TIP 602 removed the implicit tilde substitution from Tcl's handling of file paths. The file home and file tildeexpand commands made equivalent functionality explicitly available to scripts. However, no comparable C API was made available to extensions. This TIP remedies the oversight.

Re: [TCLCORE] Tcl 9.0.0 RELEASED

[Gustaf N. (sslmail) <ne...@wu...>]

Great news, great work!

There is now also a version of OpenACS based on Tcl 9.0.0, which passes its regression test (40855 tests) [1].

For all not familiar with OpenACS, it is essentially a component based web community system developed in Tcl over the last 20+ years.
Although it contains a substantial amount of Tcl code, only a few changes were needed for OpenACS 5.10.1 (released a month ago).

all the best

Re: [TCLCORE] TclYAML 0.6 released

[Andreas K. <and...@gm...>]

> I am pleased to announce TclYAML 0.6 supporting Tcl 9.

Something I forgot to put in all the announcements and was nicely
reminded of today is that I did not explain what the package actually
is for:

The TclYAML package is a binding to the libyaml library, the reference
implementation of the YAML configuration language, providing the
ability to parse and generate YAML document to Tcl scripts.

Re: [TCLCORE] Kettle 1.1 released

[Andreas K. <and...@gm...>]

> Hi all.
> 
> I am pleased to announce Kettle 1.1.

Something I forgot to put in all the announcements and was nicely
reminded of today is that I did not explain what the package actually
is for:

Kettle is an opinionated application supporting developers in
building, testing, (un)installing, etc. of Tcl packages and
applications.

Given a `build.tcl` script/specification file like

```
#!/bin/sh
# -*- tcl -*- \
exec ./kettle -f "$0" "${1+$@}"
kettle tcl
kettle tclapp kettle
```

running `build.tcl install` automatically searches the directory for
Tcl packages and the `kettle` application and installs
them. Documentation too, if found.

This simplicity of course comes on the other side with the developer
having to follow the patterns the Kettle looks for to detect packages,
documentation, testsuites, benchmarks, etc.

Re: [TCLCORE] AnKH 1.1 Release

> I am pleased to announce AnKH 1.1 supporting Tcl 9.

Something I forgot to put in all the announcements and was nicely
reminded of today is that I did not explain what the package actually
is for:

AnKH stands for Andreas Kupries Hashes.

Written in CriTcl it is a binding to a multitude of cryptographic
hashes provided by the RHash project. With it Tcl scripts have the
ability to compute all the supported hashes for strings, channels, and
files.

Re: [TCLCORE] Critcl 3.3 RELEASED

[Andreas K. <and...@gm...>]

> Hi all.
> 
> I am pleased to announce the release of Critcl 3.3.


Something I forgot to put in all the announcements and was nicely
reminded of today is that I did not explain what the package actually
is for:

CriTcl is the C Runtime (in) Tcl, enabling the mixing and use of Tcl
and C code together.

While the package by itself supports only dynamically compiling the C
parts of a package at runtime, and thus requiring a proper C compiler
in the installation/production, the adjunct Tcl application, also
caled `critcl` enables the ahead-of-time compilation of such packages
into propers extension mixing Tcl and a binary shared libraries.

Something I forgot to put in all the announcements and was nicely
reminded of today is that I did not explain what the package actually
is for:

Tcllib is a large bundle of a bit over 400 utility packages for many
occasions. Note that the number would not be that high if we there
counting the families strongly related packages as single.

[TCLCORE] ANNOUNCE: cookit v2.2.0

[Konstantin K. <ch...@gm...>]

Hi Everyone!

I am pleased to announce version 2.2.0 of cookit - tclkit-like Tcl
runtime environment with Tcl 8.6.15 and Tcl 9.0.0 with a focus on a
balance between functionality and executable size

Homepage and downloads are on github: https://github.com/chpock/cookit

Here is just a basic description of it. All details can be found on the
website home page.

Please feel free to check/build/use it. Any feedback is welcome!

=====================================================================

Cookit is a Tcl/Tk runtime environment similar to tclkit with a focus
on a balance between functionality and executable size. It allows using
Tcl/Tk in both console mode and graphical mode to run Tcl scripts, as
well as packaging applications into a single executable without
external dependencies.

Cookit is a single executable file that contains:

  * Tcl/Tk version 8.6.15 (with Threads enabled) or 9.0.0
  * Statically linked packages: cookfs, tclvfs, Threads, tclmtls, tdom,
    twapi (for Windows platform)
  * Other packages: tkcon

Supported platforms:

  * Linux x86 / x86_64
  * Windows x86 / x86_64
  * macOS x86_64

This means that Cookit can be easily and simply used to develop both
console and GUI applications, which can be multi-threaded, send HTTPS
requests to third-party services, process the received JSON/XML
response with tdom. For debugging in GUI mode a convenient and uniform
on all platforms console tkcon is available. After development, the
application can be packaged into a single executable file without
dependencies and used in other environments as a standalone application.

It can also be used as a replacement for tclsh/wish.

At the same time, the executable file has minimal size.

  * for Linux platform: executable file without Tk - about 1.1MB,
    executable file with Tk - about 1.7MB
  * for Windows platform: executable without Tk - about 1.5MB,
    executable with Tk - about 2MB.

This is an amazing size considering the ability to create GUI
applications with support for SSL/TLS connections, work with JSON/XML
documents, extensive access to WinAPI using twapi on Windows platform.
In normal installations, only the size of the OpenSSL library will be 2
times larger.

As a use case, consider an internal installer that works in both
console and GUI mode and contains the same code for all platforms. This
installer uses the REST GitHub API via HTTPS to get information about
the latest available release, uses tdom to parse the JSON response,
downloads a platform-appropriate tar.gz archive from GitHub releases
using HTTPS, mounts the resulting tar.gz archive using tclvfs and
extracts the necessary files to the destination directory.

A birth is a joyful occasion, yet also one where we expect...

... there will be screaming
... there will be crying
... and someone will get slapped

Happy Birthday anyway.  Let's see what this baby can do.
