141
<p>Welcome to the <i class="term">C Runtime In Tcl</i>, <i class="term"><a href="critcl_pkg.html">CriTcl</a></i> for short, a
142
system to build C extension packages for Tcl on the fly, from C code
143
embedded within Tcl scripts, for all who wish to make their code go
145
<p>This document provides an overview of the changes <b class="package"><a href="critcl_pkg.html">critcl</a></b>
146
underwent from version to version.</p>
148
<div id="section2" class="section"><h2><a name="section2">Changes for version 2.1</a></h2>
149
<ol class="enumerated">
150
<li><p>Fixed bug where <b class="cmd">critcl::tsources</b> interpreted relative
151
paths as relative to the current working directory instead of
152
relative to the "<b class="file">.critcl</b>" file using the command, as all other
153
commands of this type do.</p></li>
154
<li><p>Fixed internals, preventing information collected for multiple
155
"<b class="file">.critcl</b>" files to leak between them. Notably, <b class="cmd">critcl::tk</b>
156
is not a global configuration option anymore.</p></li>
157
<li><p>Fixed the command <b class="cmd">critcl::license</b> to be a null-operation
158
in mode "compile & run", instead of throwing an error.</p></li>
159
<li><p>Fixed the critcl application's interference with the "compile &
160
run" result cache in <b class="option">-pkg</b> mode by having it use a wholly
161
separate (and by default transient) directory for that mode.</p></li>
162
<li><p>Fixed bug where changes to a "<b class="file">.critcl</b>" file did not result
163
in a rebuild for mode "compile & run". All relevant API commands now
164
ensure UUID changes.</p></li>
165
<li><p>Fixed bug in the backend handling of <b class="cmd">critcl::debug</b> where
166
the companion c-sources of a "<b class="file">.critcl</b>" file were not compiled
167
with debug options, although the "<b class="file">.critcl</b>" file was.</p></li>
168
<li><p>Fixed bug in <b class="cmd">critcl::debug</b> which prevented recognition of
169
mode "all" when it was not the first argument to the command.</p></li>
170
<li><p>Fixed bug in "<b class="file">preload.c</b>" preventing its compilation on
171
non-windows platforms.</p></li>
172
<li><p>Fixed long-standing bug in the handling of namespace qualifiers
173
in the command name argument of <b class="cmd">critcl::cproc</b> and
174
<b class="cmd">critcl::ccommand</b>. It is now possible to specify a fully
175
qualified command name without issues.</p></li>
176
<li><p>Extended/reworked <b class="cmd">critcl::tsources</b> to be the canonical
177
way of declaring "<b class="file">.tcl</b>" companion files even for mode "compile &
179
<li><p>Extended/reworked <b class="cmd">critcl::tsources</b> to allow the use of a
180
"<b class="file">.critcl</b>" file as its own Tcl companion file.</p></li>
181
<li><p>Extended <b class="cmd">critcl::framework</b> to internally check for OS X
182
build target, and to ignore the declaration if its not.</p></li>
183
<li><p>Extended <b class="cmd">critcl::failed</b> to be callable more than once in
184
a "<b class="file">.critcl</b>" file. The first call forces the build, if it was not
185
done already, to get the result. Further calls return the cached
186
result of the first call.</p></li>
187
<li><p>Extended the handling of environment variable CC in the code
188
determining the compiler to use to deal with (i.e. remove) paths to
189
the compiler, compiler file extensions, and compiler options specified
190
after the compiler itself, leaving only the bare name of the compiler.</p></li>
191
<li><p>Extended the code handling the search for preloaded libraries
192
to print the paths it searched, making debugging of a search failure
194
<li><p>A new command <b class="cmd">critcl::tcl</b> can be used to declare the
195
version of Tcl minimally needed to build and run the "<b class="file">.critcl</b>"
196
file and package. Defaults to 8.4 if not declared. Extended critcl to
197
have the stubs and headers for all of Tcl 8.4, 8.5, and 8.6.</p></li>
198
<li><p>A new command <b class="cmd">critcl::load</b> forces the build and load of a
199
"<b class="file">.critcl</b>" file. This is the official way for overriding critcl's
200
default lazy-build-&-load-on-demand scheme for mode "compile & run".</p>
201
<p><em>Note</em> that after using <b class="cmd">critcl::load</b> /
202
<b class="cmd">critcl::failed</b> in a "<b class="file">.critcl</b>" file it is not possible to
203
use critcl commands in that file anymore. Doing so will throw an
205
<li><p>Extended the generation of '#line' pragmas to use
206
<b class="cmd">info frame</b> (if available) to provide the C compiler with exact
207
line numbers into the "<b class="file">.critcl</b>" file for the reporting of
208
warnings and errors.</p></li>
209
<li><p>Extended <b class="cmd">critcl::check</b> with logging to help with
210
debugging build-time checks of the environment, plus an additional
211
optional argument to provide labeling.</p></li>
212
<li><p>Added a new command <b class="cmd">critcl::checklink</b> which not only
213
tries to check the environment via compiling the code, but also
214
its linkability.</p></li>
215
<li><p>Added a new command <b class="cmd">critcl::msg</b> for messaging, like
216
command <b class="cmd">critcl::error</b> is for error reporting. Likewise this is a
217
hook a user of the package is allowed to override. The default
218
implementation, used by mode <i class="term"><a href="../index.html#key0">compile & run</a></i> does nothing. The
219
implementation for mode <i class="term"><a href="../index.html#key9">generate package</a></i> prints the message
221
<p>Envisioned use is for the reporting of results determined by
222
<b class="cmd">critcl::check</b> and <b class="cmd">critcl::checklink</b> during building, to
223
help with debugging when something goes wrong with a check.</p></li>
224
<li><p>Exposed the argument processing internals of <b class="cmd">critcl::proc</b>
225
for use by advanced users. The new commands are</p>
226
<ol class="enumerated">
227
<li><p><b class="cmd">critcl::argnames</b></p></li>
228
<li><p><b class="cmd">critcl::argcnames</b></p></li>
229
<li><p><b class="cmd">critcl::argcsignature</b></p></li>
230
<li><p><b class="cmd">critcl::argvardecls</b></p></li>
231
<li><p><b class="cmd">critcl::argconversion</b></p></li>
233
<p>Please see section <em>Advanced Embedded C Code</em> of the
234
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>
235
<li><p>Extended the critcl package to intercept <b class="cmd">package
236
provide</b> and record the file -> package name mapping. Plus other
237
internal changes now allow the use of namespaced package names while
238
still using proper path names and init function.</p></li>
239
<li><p>Dropped the unused commands <b class="cmd">critcl::optimize</b> and
240
<b class="cmd">critcl::include</b>.</p></li>
241
<li><p>Dropped <b class="option">-lib</b> mode from the critcl application.</p></li>
242
<li><p>Dropped remnants of support for Tcl 8.3 and before.</p></li>
245
<div id="section3" class="section"><h2><a name="section3">Changes for version 3</a></h2>
246
<ol class="enumerated">
247
<li><p>The command <b class="cmd">critcl::platform</b> was deprecated in version
248
2.1, superceded by <b class="cmd">critcl::targetplatform</b>, yet kept for
249
compatibility. Now it has been removed.</p></li>
250
<li><p>The command <b class="cmd">critcl::compiled</b> was kept with in version 2.1
251
with semantics in contradiction to its, for compatibility. This
252
contradiction has been removed, changing the visible semantics of the
253
command to be in line with its name.</p></li>
254
<li><p>The change to version 3 became necessary because of the two
255
incompatible visible changes above.</p></li>
256
<li><p>Extended the application package with code handling a new
257
option <b class="option">-tea</b>. Specifying this option invokes a special mode
258
where critcl generates a TEA package, i.e. wraps the input into a
259
directory hierarchy and support files which provide it TEA-lookalike
261
<p>This new option, and <b class="option">-pkg</b>, exclude each other. If
262
both are specified the last used option takes precedence.</p>
263
<p>The generated package directory hierarchy is mostly
264
self-contained, but not fully. It requires not only a working
265
installation of Tcl, but also working installations of the packages
266
<b class="package">md5</b> and <b class="package">cmdline</b>. Both of these are provided by the
267
<b class="package">Tcllib</b> bundle. Not required, but recommended to have
268
installed are any of the packages which can accelerate md5's
269
operation, i.e. <b class="package">cryptkit</b>, <b class="package">tcllibc</b>, or
270
<b class="package">Trf</b>.</p></li>
271
<li><p>Extended the critcl package with a new command
272
<b class="cmd">critcl::scan</b> taking the path to a "<b class="file">.critcl</b>" file,
273
statically scanning it, and returning license, version, a list of its
274
companion files, list of imported APIs, and list of
275
developer-specified custom configuration options. This data is the
276
foundation for the TEA wrapping described above.</p>
277
<p>Note that this is a <em>static</em> scan. While the other build
278
modes can (must) execute the "<b class="file">.critcl</b>" file and make
279
platform-specific decisions regarding the assembled C code, companion
280
files, etc. the TEA wrap mode is not in a position to make
281
platform-specific decisions. It has to wrap everything which might
282
conceivably be needed when actually building. Hence the static scan.
283
This has however its own set of problems, namely the inability to
284
figure out any dynamic construction of companion file paths, at least
285
on its own. Thus:</p></li>
286
<li><p>Extended the API used by critcl-based packages with the command
287
<b class="cmd">critcl::owns</b>. While this command is ignored by the regular build
288
modes the static scanner described above takes its arguments as the
289
names of companion files which have to be wrapped into the TEA package
290
and could not be figured by the scanner otherwise, like because of
291
dynamic paths to <b class="cmd">critcl::tsources</b>, <b class="cmd">critcl::csources</b>,
292
getting sourced directly, or simply being adjunct datafiles.</p></li>
293
<li><p>Extended the API used by critcl-based packages with the command
294
<b class="cmd">critcl::api</b> for the management of stubs tables, be it their use,
295
and/or declaration and export.</p>
296
<p>Please see section <em>Stubs Table Management</em> of the
297
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>
298
<li><p>Extended the API used by critcl-based packages with the command
299
<b class="cmd">critcl::userconfig</b> for the management of developer-specified
300
custom configuration options, be it their use and/or declaration.</p>
301
<p>Please see section <em>Custom Build Configuration</em> of the
302
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>
303
<li><p>Extended the API used by critcl-based packages with the
304
commands <b class="cmd">critcl::description</b>, <b class="cmd">critcl::summary</b>,
305
<b class="cmd">critcl::subject</b>, <b class="cmd">critcl::meta</b>, and
306
<b class="cmd">critcl::buildrequirement</b> for the declaration of TEApot meta data
307
for/about the package.</p>
308
<p>Please see section <em>Package Meta Data</em> of the
309
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>

<div id="section4" class="section"><h2><a name="section4">Changes for version 3.0.1</a></h2>
313
<ol class="enumerated">
314
<li><p>Bugfixes all around. In detail:</p></li>
315
<li><p>Fixed recording of Tcl version requirements. Keep package name
316
and version together, unbreaking generated meta data and generated
317
package load command.</p></li>
318
<li><p>Fixed the build scripts: When installing, or wrapping for TEA,
319
generate any missing directories</p></li>
320
<li><p>Modified the build scripts to properly exit the application
321
when the window of their GUI is closed through the (X) button.</p></li>
322
<li><p>Removed an 8.5-ism (open wb) which had slipped into the main
323
build script.</p></li>
324
<li><p>Modified the example build scripts to separate the output for
325
the different examples (and packages) by adding empty lines.</p></li>
326
<li><p>stack::c example bugfix: Include API declarations for use in
327
the companion files.</p></li>
328
<li><p>Extended the documentation: Noted the need for a working
329
installation of a C compiler.</p></li>
330
<li><p>Extended the Windows target definitions and code to handle the
331
manifest files used by modern MS development environments. Note that
332
this code handles both possibilities, environment using manifests, and
333
(old(er)) environments without.</p></li>
334
<li><p>Extended the Windows 64bit target definitions and code to
335
auto-detect the need for the helper library "bufferoverflowU.lib" and
336
reconfigure the compile and link commands appropriately. We assume
337
that the library must be linked when present. This should be no harm
338
if the library is present, yet not needed. Just superfluous. We search
339
for the library in the paths specified by the environment variable

<div id="section5" class="section"><h2><a name="section5">Changes for version 3.0.2</a></h2>
344

345
<li><p>Fixed issue in compile-and-run mode where commands put into the
346
auto_index are not found by Tcl's [unknown] command.</p></li>
347
<li><p>Fixed an array key mismatch breaking usage of client data and
348
delete function for procedure. Reported by Jos DeCoster, with patch.</p></li>
349
<li><p>Implemented a command line option <b class="option">-L</b>, an equivalent of
350
option <b class="option">-I</b>, just for library search paths.</p></li>
351
<li><p>Fixed github issues 5 and 8. Working around a missing variable
352
::errorInfo. It should always be present, however there seem to be
353
revisions of Tcl around which violate this assumption.</p></li>

366
<li><p>Fixed generation of the package's initname when the incoming
367
code is read from stdin and has no proper path.</p></li>
368
<li><p>Fixed github issue 11. Now using /LIBPATH instead of -L
369
on Windows (libinclude configuration setting).</p></li>
370
<li><p>Extended critcl to handle -l:path format of -l options.
371
GNU ld 2.22+ handles this by searching for the path as
372
is. Good when specifying static libraries, as plain -l looks
373
for shared libraries in preference over static. critcl handles
374
it now, as older GNU ld's do not understand it, nor the
375
various vendor-specific linkers.</p></li>
376
<li><p>Fixed github issue #12. Critcl now determines the version of
377
MSVC in use and uses it to switch between various link debug
378
options. Simplified the handling of bufferoverflowU.lib also,
379
making use of the same mechanism and collapsing the two
380
configurations sections we had back into one.</p></li>
381
<li><p>Reworked the insertion of #line pragmas into the generated C
382
code to avoid limitations on the line number argument imposed
383
by various compilers, and be more accurate.</p></li>
384
<li><p>Modified argument processing. Option -libdir now also
385
implies -L for its argument.</p></li>
386
<li><p>Extended handling of option -show (<b class="cmd">critcl::showconfig</b>)
387
to list the path of the configuration file the data is coming
388
from. Good for debugging configuration processing.</p></li>
389

390
embedded documentation, and diagrams, and to generate a

proper exit code (1) on build failure, instead of always

407
<li><p>Fixed github issue 13. Handling of bufferoverflowU.lib for
408
release builds was inconsistent with handling for debug
409
builds. It is now identically handled (conditional) by

418
The emitted code handed a non-static string table to

with class- and instance-variables and -methods similar to a TclOO
438
class, with all the necessary boilerplate C code to support this
439
generated by the package.</p>
440
<p>This package uses several of the new features which were added
441
to the core <b class="package"><a href="critcl_pkg.html">critcl</a></b> package, see below.</p></li>
442
<li><p>Extended the API for handling TEApot metadata. Added the
443
command <b class="cmd">critcl::meta?</b> to query the stored information. Main use
444
currently envisioned is retrieval of the current package's name by
445
utility commands, for use in constructed names. This particular
446
information is always available due to the static scan of the package
447
file on execution of the first critcl command.</p>
448
<p>The new packages <b class="package"><a href="critcl_iassoc.html">critcl::iassoc</a></b> and
449
<b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) are users of this command.</p></li>
450
<li><p>Extended the API with a command, <b class="cmd">critcl::name2c</b>, exposing
451
the process of converting a Tcl name into base name, namespace, and C
452
namespace. This enables higher-level code generators to generate the same
453
type of C identifiers as <b class="package"><a href="critcl_pkg.html">critcl</a></b> itself.</p>
454
<p>The new package <b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) is a user
455
of this command.</p></li>
456
<li><p>Extended the API with a command, <b class="cmd">critcl::source</b>,
457
executing critcl commands found in a separate file in the context of
458
the current file. This enables easier management of larger bodies of
459
code as it allows the user to split such up into easier to digest
460
smaller chunks without causing the generation of multiple packages.</p></li>
461
<li><p>Related to the previous item, extended the API with commands to
462
divert collection of generated C code into memory. This makes it
463
easier to use the commands for embedded C code in higher-level code
465
<p>See the section <b class="sectref">Advanced: Diversions</b> for details of
466
the provided commands.</p>
467
<p>The new package <b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) is a user
468
of these facilities.</p></li>
469
<li><p>Extended the API with commands helping developers with the
470
generation of proper C <i class="term">#line</i> directives. This allows
471
higher-level code generators to generate and insert their own
472
directives, ensuring that compile errors in their code are properly
474
<p>See the section <b class="sectref">Advanced: Location management</b> for
475
details of the provided commands.</p>
476
<p>The new packages <b class="package"><a href="critcl_iassoc.html">critcl::iassoc</a></b> and
477
<b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) are users of these facilities.</p></li>
478
<li><p>Extended the API with commands giving users the ability to
479
define custom argument and result types for <b class="cmd">::critcl::cproc</b>.</p>
480
<p>See the section <b class="sectref">Advanced: Extending cproc</b> for
481
details of the provided commands.</p></li>

512
<li><p>Added new argument type "pstring", for "Pascal String", a
513
counted string, i.e. a combination of string pointer and string
515
<li><p>Added new methods <b class="cmd">critcl::argtypesupport</b> and

528
field in the class structure if the class has no class
529
variables. Without this change the structure would be empty,
530
and a number of compilers are not able to handle such a type.</p></li>
531
<li><p>Fixed a typo which broke the win64 configuration.</p></li>
532

538
<li><p>Fixed issue #19. Made the regular expression extracting the
539
MSVC version number more general to make it work on german
540
language systems. This may have to be revisited in the future,
541
for other Windows locales.</p></li>
542
<li><p>Fixed issue #20. Made option -tea work on windows, at least in
543
a unix emulation environment like msys/mingw.</p></li>
546
<div id="section17" class="section"><h2><a name="section17">Changes for version 3.1.6</a></h2>

<li><p>Fixed issue #21. While the multi-definition of the stub-table
549
pointer variables was ok with for all the C linkers seen so far
550
C++ linkers did not like this at all. Reworked the code to
551
ensure that this set of variables is generated only once, in
552
the wrapper around all the pieces to assemble.</p></li>
553
<li><p>Fixed issue #22, the handling of the command identifier
554
arguments of <b class="cmd">critcl::ccommand</b>, <b class="cmd">critcl::cproc</b>, and
555
<b class="cmd">critcl::cdata</b>. We now properly allow any Tcl identifier
556
and generate proper internal C identifiers from them.</p>
557
<p>As part of this the signature of command <b class="cmd">critcl::name2c</b>
558
changed. The command now delivers a list of four values instead
559
of three. The new value was added at the end.</p>
560
<p>Further adapted the implementation of package
561
<b class="package"><a href="critcl_class.html">critcl::class</a></b>, a user of <b class="cmd">critcl::name2c</b>.
562
This package is now at version 1.0.6 and requires critcl 3.1.6</p>

573
still indicate problems.</p></li>
574
<li><p>New feature. Output hook. All non-messaging user output is now

597
include directives derived from it.</p></li>
598
<li><p>Fixed the issue behind rejected pull request #30 by Andrew
599
Shadura. Dynamically extract the stubs variable declarations
600
from the Tcl header files and generate matching variable
601
definitions for use in the package code. The generated code
602
will now be always consistent with the headers, even when
603
critcl's own copy of them is replaced by system headers.</p></li>
604
<li><p>Fixed issue #31. Accepted patch by Andrew Shadura, with
