310
<dd><p>The default mode of the application is to build the "<b class="file">.critcl</b>"
311
files listed on the command line and save the results in the result
312
cache. Essentially pre-filling the cache with important packages,
313
cutting down on the time needed to use these packages.</p>
314
<p>This option activates one of the other modes, package generation.
315
In this mode the input files are processed first as usual, however
316
after that they are bundled into a single library and additional files
317
are generated to make this library usable as a regular Tcl package.</p>
318
<p>The option <b class="option">-tea</b>, see below, invokes the last mode, TEA
319
generation. If both options, i.e. <b class="option">-pkg</b> and <b class="option">-tea</b> are
320
specified the last one specified wins.</p>
321
<p>In this mode the options <b class="option">-clean</b> and <b class="option">-force</b> are
322
irrelevant and ignored. In contrast, the option <b class="option">-libdir</b> is
323
relevant in both this and <b class="option">-tea</b> mode.</p>
324
<p>When this option is specified the basename of the first file argument
325
after the options is used as the name of the package to generate. If
326
the extension of that file indicates a shared library ("<b class="file">.so</b>",
327
"<b class="file">.sl</b>", "<b class="file">.dylib</b>", and "<b class="file">.dll</b>") it is also removed from
328
the set of input files. A "<b class="file">.tcl</b>" file is kept as part of the
329
input. A single file without extension is assumed to actually have a
330
"<b class="file">.tcl</b>" extension. A file without extension, but other input files
331
following is treated like the name of a shared library proper, and
332
removed from the set of input files.</p>

437
<p>CriTcl can be used in three different modes of operation, called</p>
438
<ol class="enumerated">
439
<li><p><i class="term"><a href="../index.html#key0">Compile & Run</a></i>, and</p></li>
440
<li><p><i class="term"><a href="../index.html#key9">Generate Package</a></i></p></li>
441
<li><p><i class="term">Generate TEA Package</i></p></li>
443
<p>Of these three <i class="term"><a href="../index.html#key0">Compile & Run</a></i> came first and is the default
444
when using the package directly. In that case the package collects the
445
C fragments, builds them as needed, and caches the results for quick
446
reuse when the same code is used in the future again.</p>
447
<p>The second mode, <i class="term"><a href="../index.html#key9">Generate Package</a></i>, was introduced to enable
448
the creation of (prebuilt) deliverable packages which do not depend on
449
the existence of a build system, i.e. C compiler, on the target
451
This was originally done through the experimental <b class="cmd">Critbind</b> tool,
452
and is now handled by the <i class="term"><a href="critcl_app.html">CriTcl Application</a></i>, also named
453
<b class="cmd"><a href="critcl_pkg.html">critcl</a></b>.</p>
454
<p>Newly introduced with Critcl version 3 is
455
<i class="term">Generate TEA Package</i>. This mode constructs a directory
456
hierarchy from the package which can later be built like a regular TEA
457
package, i.e. using</p>

<div id="section5" class="section"><h2><a name="section5">Package Structure</a></h2>

<div id="section6" class="section"><h2><a name="section6">Changes for version 2.1</a></h2>
519
<ol class="enumerated">
520
<li><p>Fixed bug where <b class="cmd">critcl::tsources</b> interpreted relative
521
paths as relative to the current working directory instead of
522
relative to the "<b class="file">.critcl</b>" file using the command, as all other
523
commands of this type do.</p></li>
524
<li><p>Fixed internals, preventing information collected for multiple
525
"<b class="file">.critcl</b>" files to leak between them. Notably, <b class="cmd">critcl::tk</b>
526
is not a global configuration option anymore.</p></li>
527
<li><p>Fixed the command <b class="cmd">critcl::license</b> to be a null-operation
528
in mode "compile & run", instead of throwing an error.</p></li>
529
<li><p>Fixed the critcl application's interference with the "compile &
530
run" result cache in <b class="option">-pkg</b> mode by having it use a wholly
531
separate (and by default transient) directory for that mode.</p></li>
532
<li><p>Fixed bug where changes to a "<b class="file">.critcl</b>" file did not result
533
in a rebuild for mode "compile & run". All relevant API commands now
534
ensure UUID changes.</p></li>
535
<li><p>Fixed bug in the backend handling of <b class="cmd">critcl::debug</b> where
536
the companion c-sources of a "<b class="file">.critcl</b>" file were not compiled
537
with debug options, although the "<b class="file">.critcl</b>" file was.</p></li>
538
<li><p>Fixed bug in <b class="cmd">critcl::debug</b> which prevented recognition of
539
mode "all" when it was not the first argument to the command.</p></li>
540
<li><p>Fixed bug in "<b class="file">preload.c</b>" preventing its compilation on
541
non-windows platforms.</p></li>
542
<li><p>Fixed long-standing bug in the handling of namespace qualifiers
543
in the command name argument of <b class="cmd">critcl::cproc</b> and
544
<b class="cmd">critcl::ccommand</b>. It is now possible to specify a fully
545
qualified command name without issues.</p></li>
546
<li><p>Extended/reworked <b class="cmd">critcl::tsources</b> to be the canonical
547
way of declaring "<b class="file">.tcl</b>" companion files even for mode "compile &
549
<li><p>Extended/reworked <b class="cmd">critcl::tsources</b> to allow the use of a
550
"<b class="file">.critcl</b>" file as its own Tcl companion file.</p></li>
551
<li><p>Extended <b class="cmd">critcl::framework</b> to internally check for OS X
552
build target, and to ignore the declaration if its not.</p></li>
553
<li><p>Extended <b class="cmd">critcl::failed</b> to be callable more than once in
554
a "<b class="file">.critcl</b>" file. The first call forces the build, if it was not
555
done already, to get the result. Further calls return the cached
556
result of the first call.</p></li>
557
<li><p>Extended the handling of environment variable CC in the code
558
determining the compiler to use to deal with (i.e. remove) paths to
559
the compiler, compiler file extensions, and compiler options specified
560
after the compiler itself, leaving only the bare name of the compiler.</p></li>
561
<li><p>Extended the code handling the search for preloaded libraries
562
to print the paths it searched, making debugging of a search failure
564
<li><p>A new command <b class="cmd">critcl::tcl</b> can be used to declare the
565
version of Tcl minimally needed to build and run the "<b class="file">.critcl</b>"
566
file and package. Defaults to 8.4 if not declared. Extended critcl to
567
have the stubs and headers for all of Tcl 8.4, 8.5, and 8.6.</p></li>
568
<li><p>A new command <b class="cmd">critcl::load</b> forces the build and load of a
569
"<b class="file">.critcl</b>" file. This is the official way for overriding critcl's
570
default lazy-build-&-load-on-demand scheme for mode "compile & run".</p>
571
<p><em>Note</em> that after using <b class="cmd">critcl::load</b> /
572
<b class="cmd">critcl::failed</b> in a "<b class="file">.critcl</b>" file it is not possible to
573
use critcl commands in that file anymore. Doing so will throw an
575
<li><p>Extended the generation of '#line' pragmas to use
576
<b class="cmd">info frame</b> (if available) to provide the C compiler with exact
577
line numbers into the "<b class="file">.critcl</b>" file for the reporting of
578
warnings and errors.</p></li>
579
<li><p>Extended <b class="cmd">critcl::check</b> with logging to help with
580
debugging build-time checks of the environment, plus an additional
581
optional argument to provide labeling.</p></li>
582
<li><p>Added a new command <b class="cmd">critcl::checklink</b> which not only
583
tries to check the environment via compiling the code, but also
584
its linkability.</p></li>
585
<li><p>Added a new command <b class="cmd">critcl::msg</b> for messaging, like
586
command <b class="cmd">critcl::error</b> is for error reporting. Likewise this is a
587
hook a user of the package is allowed to override. The default
588
implementation, used by mode <i class="term"><a href="../index.html#key0">compile & run</a></i> does nothing. The
589
implementation for mode <i class="term"><a href="../index.html#key9">generate package</a></i> prints the message
591
<p>Envisioned use is for the reporting of results determined by
592
<b class="cmd">critcl::check</b> and <b class="cmd">critcl::checklink</b> during building, to
593
help with debugging when something goes wrong with a check.</p></li>
594
<li><p>Exposed the argument processing internals of <b class="cmd">critcl::proc</b>
595
for use by advanced users. The new commands are</p>

<p>Please see section <em>Advanced Embedded C Code</em> of the
604
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>
605
<li><p>Extended the critcl package to intercept <b class="cmd">package
606
provide</b> and record the file -> package name mapping. Plus other
607
internal changes now allow the use of namespaced package names while
608
still using proper path names and init function.</p></li>
609
<li><p>Dropped the unused commands <b class="cmd">critcl::optimize</b> and
610
<b class="cmd">critcl::include</b>.</p></li>
611
<li><p>Dropped <b class="option">-lib</b> mode from the critcl application.</p></li>
612
<li><p>Dropped remnants of support for Tcl 8.3 and before.</p></li>
615
<div id="section7" class="section"><h2><a name="section7">Changes for version 3</a></h2>
616
<ol class="enumerated">
617
<li><p>The command <b class="cmd">critcl::platform</b> was deprecated in version
618
2.1, superceded by <b class="cmd">critcl::targetplatform</b>, yet kept for
619
compatibility. Now it has been removed.</p></li>
620
<li><p>The command <b class="cmd">critcl::compiled</b> was kept with in version 2.1
621
with semantics in contradiction to its, for compatibility. This
622
contradiction has been removed, changing the visible semantics of the
623
command to be in line with its name.</p></li>
624
<li><p>The change to version 3 became necessary because of the two
625
incompatible visible changes above.</p></li>
626
<li><p>Extended the application package with code handling a new
627
option <b class="option">-tea</b>. Specifying this option invokes a special mode
628
where critcl generates a TEA package, i.e. wraps the input into a
629
directory hierarchy and support files which provide it TEA-lookalike
631
<p>This new option, and <b class="option">-pkg</b>, exclude each other. If
632
both are specified the last used option takes precedence.</p>
633
<p>The generated package directory hierarchy is mostly
634
self-contained, but not fully. It requires not only a working
635
installation of Tcl, but also working installations of the packages
636
<b class="package">md5</b> and <b class="package">cmdline</b>. Both of these are provided by the
637
<b class="package">Tcllib</b> bundle. Not required, but recommended to have
638
installed are any of the packages which can accelerate md5's
639
operation, i.e. <b class="package">cryptkit</b>, <b class="package">tcllibc</b>, or
640
<b class="package">Trf</b>.</p></li>
641
<li><p>Extended the critcl package with a new command
642
<b class="cmd">critcl::scan</b> taking the path to a "<b class="file">.critcl</b>" file,
643
statically scanning it, and returning license, version, a list of its
644
companion files, list of imported APIs, and list of
645
developer-specified custom configuration options. This data is the
646
foundation for the TEA wrapping described above.</p>
647
<p>Note that this is a <em>static</em> scan. While the other build
648
modes can (must) execute the "<b class="file">.critcl</b>" file and make
649
platform-specific decisions regarding the assembled C code, companion
650
files, etc. the TEA wrap mode is not in a position to make
651
platform-specific decisions. It has to wrap everything which might
652
conceivably be needed when actually building. Hence the static scan.
653
This has however its own set of problems, namely the inability to
654
figure out any dynamic construction of companion file paths, at least
655
on its own. Thus:</p></li>
656
<li><p>Extended the API used by critcl-based packages with the command
657
<b class="cmd">critcl::owns</b>. While this command is ignored by the regular build
658
modes the static scanner described above takes its arguments as the
659
names of companion files which have to be wrapped into the TEA package
660
and could not be figured by the scanner otherwise, like because of
661
dynamic paths to <b class="cmd">critcl::tsources</b>, <b class="cmd">critcl::csources</b>,
662
getting sourced directly, or simply being adjunct datafiles.</p></li>
663
<li><p>Extended the API used by critcl-based packages with the command
664
<b class="cmd">critcl::api</b> for the management of stubs tables, be it their use,
665
and/or declaration and export.</p>
666
<p>Please see section <em>Stubs Table Management</em> of the
667
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>
668
<li><p>Extended the API used by critcl-based packages with the command
669
<b class="cmd">critcl::userconfig</b> for the management of developer-specified
670
custom configuration options, be it their use and/or declaration.</p>
671
<p>Please see section <em>Custom Build Configuration</em> of the
672
<b class="package"><a href="critcl_pkg.html">critcl</a></b> package documentation for details.</p></li>
673
<li><p>Extended the API used by critcl-based packages with the
674
commands <b class="cmd">critcl::description</b>, <b class="cmd">critcl::summary</b>,
675
<b class="cmd">critcl::subject</b>, <b class="cmd">critcl::meta</b>, and
676
<b class="cmd">critcl::buildrequirement</b> for the declaration of TEApot meta data

for/about the package.</p>

684
<li><p>Bugfixes all around. In detail:</p></li>

686

687
package load command.</p></li>
688
<li><p>Fixed the build scripts: When installing, or wrapping for TEA,
689
generate any missing directories</p></li>

<li><p>Modified the build scripts to properly exit the application
691
when the window of their GUI is closed through the (X) button.</p></li>
692
<li><p>Removed an 8.5-ism (open wb) which had slipped into the main

build script.</p></li>
694
<li><p>Modified the example build scripts to separate the output for
695
the different examples (and packages) by adding empty lines.</p></li>
696
<li><p>stack::c example bugfix: Include API declarations for use in
697
the companion files.</p></li>
698
<li><p>Extended the documentation: Noted the need for a working
699
installation of a C compiler.</p></li>
700
<li><p>Extended the Windows target definitions and code to handle the
701
manifest files used by modern MS development environments. Note that
702
this code handles both possibilities, environment using manifests, and
703
(old(er)) environments without.</p></li>
704
<li><p>Extended the Windows 64bit target definitions and code to
705
auto-detect the need for the helper library "bufferoverflowU.lib" and
706
reconfigure the compile and link commands appropriately. We assume
707
that the library must be linked when present. This should be no harm
708
if the library is present, yet not needed. Just superfluous. We search
709
for the library in the paths specified by the environment variable

<li><p>Fixed github issue 11. Now using /LIBPATH instead of -L
739
on Windows (libinclude configuration setting).</p></li>
740
<li><p>Extended critcl to handle -l:path format of -l options.
741
GNU ld 2.22+ handles this by searching for the path as
742
is. Good when specifying static libraries, as plain -l looks
743
for shared libraries in preference over static. critcl handles
744
it now, as older GNU ld's do not understand it, nor the
745
various vendor-specific linkers.</p></li>
746
<li><p>Fixed github issue #12. Critcl now determines the version of
747
MSVC in use and uses it to switch between various link debug
748
options. Simplified the handling of bufferoverflowU.lib also,
749
making use of the same mechanism and collapsing the two
750
configurations sections we had back into one.</p></li>
751
<li><p>Reworked the insertion of #line pragmas into the generated C
752
code to avoid limitations on the line number argument imposed
753
by various compilers, and be more accurate.</p></li>
754
<li><p>Modified argument processing. Option -libdir now also

788
The emitted code handed a non-static string table to

<ol class="enumerated">
797
<li><p>Added a new higher-level package <b class="package"><a href="critcl_iassoc.html">critcl::iassoc</a></b>.</p>
798
<p>This package simplifies the creation of code associating data
799
with an interpreter via Tcl's <b class="function">Tcl_(Get|Set)AssocData()</b> APIs. The
800
user can concentrate on his data while all the necessary boilerplate
801
C code to support this is generated by the package.</p>
802
<p>This package uses several of the new features which were added
803
to the core <b class="package"><a href="critcl_pkg.html">critcl</a></b> package, see below.</p></li>
804
<li><p>Added the higher-level package <b class="package"><a href="critcl_class.html">critcl::class</a></b>.</p>
805
<p>This package simplifies the creation of C level objects with
806
class and instance commands. The user can write a class definition
807
with class- and instance-variables and -methods similar to a TclOO
808
class, with all the necessary boilerplate C code to support this
809
generated by the package.</p>
810
<p>This package uses several of the new features which were added
811
to the core <b class="package"><a href="critcl_pkg.html">critcl</a></b> package, see below.</p></li>
812
<li><p>Extended the API for handling TEApot metadata. Added the
813
command <b class="cmd">critcl::meta?</b> to query the stored information. Main use
814
currently envisioned is retrieval of the current package's name by
815
utility commands, for use in constructed names. This particular
816
information is always available due to the static scan of the package
817
file on execution of the first critcl command.</p>
818
<p>The new packages <b class="package"><a href="critcl_iassoc.html">critcl::iassoc</a></b> and
819
<b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) are users of this command.</p></li>
820
<li><p>Extended the API with a command, <b class="cmd">critcl::name2c</b>, exposing
821
the process of converting a Tcl name into base name, namespace, and C
822
namespace. This enables higher-level code generators to generate the same
823
type of C identifiers as <b class="package"><a href="critcl_pkg.html">critcl</a></b> itself.</p>
824
<p>The new package <b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) is a user
825
of this command.</p></li>
826
<li><p>Extended the API with a command, <b class="cmd">critcl::source</b>,
827
executing critcl commands found in a separate file in the context of
828
the current file. This enables easier management of larger bodies of
829
code as it allows the user to split such up into easier to digest
830
smaller chunks without causing the generation of multiple packages.</p></li>
831
<li><p>Related to the previous item, extended the API with commands to
832
divert collection of generated C code into memory. This makes it
833
easier to use the commands for embedded C code in higher-level code
835
<p>See the section <b class="sectref">Advanced: Diversions</b> for details of
836
the provided commands.</p>
837
<p>The new package <b class="package"><a href="critcl_class.html">critcl::class</a></b> (see above) is a user
838
of these facilities.</p></li>
839
<li><p>Extended the API with commands helping developers with the
840
generation of proper C <i class="term">#line</i> directives. This allows
841
higher-level code generators to generate and insert their own
842
directives, ensuring that compile errors in their code are properly

<b class="cmd">critcl::cproc</b> and derived code (<b class="package"><a href="critcl_class.html">critcl::class</a></b>
859
cproc-based methods). Use NULL if there are no arguments, and

take the offset into account.</p></li>
861
<li><p>Fixed the handling of package names by

<b class="package"><a href="critcl_class.html">critcl::class</a></b>. Forgot that they may contain namespace
863
separators. Bumped to version 1.0.1.</p></li>

871
<li><p>Extended <b class="cmd">critcl::cproc</b> to be able to handle optional

873
<b class="package"><a href="critcl_class.html">critcl::class</a></b> cproc-based methods as well.</p></li>
874
<li><p>Bugfix in <b class="cmd">lassign</b> emulation for Tcl 8.4. Properly set

881
<li><p>Enhancement. In detail:</p></li>
882
<li><p>Added new argument type "pstring", for "Pascal String", a
883
counted string, i.e. a combination of string pointer and string
885
<li><p>Added new methods <b class="cmd">critcl::argtypesupport</b> and
886
<b class="cmd">::critcl::argsupport</b> to define and use additional
887
supporting code for an argument type, here used by "pstring"

above to define the necessary structure.</p></li>
889
<li><p>Semi-bugfixes in the packages <b class="package"><a href="critcl_class.html">critcl::class</a></b> and
890
<b class="package"><a href="critcl_iassoc.html">critcl::iassoc</a></b>. Pragmas for the AS meta data scanner
891
to ensure that the template files are made part of the package.
892
Versions bumped to 1.0.4 and 1.0.1 respectively.</p></li>

<ol class="enumerated">
897
<li><p>Bugfix in package <b class="package"><a href="critcl_class.html">critcl::class</a></b>. Generate a dummy
898
field in the class structure if the class has no class
899
variables. Without this change the structure would be empty,
900
and a number of compilers are not able to handle such a type.</p></li>
901
<li><p>Fixed a typo which broke the win64 configuration.</p></li>
902
<li><p>Fixed issue #16, a typo in the documentation of command
903
<b class="cmd"><a href="critcl_class.html">critcl::class</a></b>.</p></li>
906
<div id="section20" class="section"><h2><a name="section20">Changes for version 3.1.5</a></h2>
907
<ol class="enumerated">
908
<li><p>Fixed issue #19. Made the regular expression extracting the
909
MSVC version number more general to make it work on german
910
language systems. This may have to be revisited in the future,
911
for other Windows locales.</p></li>
912
<li><p>Fixed issue #20. Made option -tea work on windows, at least in
913
a unix emulation environment like msys/mingw.</p></li>
916
<div id="section21" class="section"><h2><a name="section21">Changes for version 3.1.6</a></h2>
917
<ol class="enumerated">
918
<li><p>Fixed issue #21. While the multi-definition of the stub-table
919
pointer variables was ok with for all the C linkers seen so far
920
C++ linkers did not like this at all. Reworked the code to
921
ensure that this set of variables is generated only once, in
922
the wrapper around all the pieces to assemble.</p></li>
923
<li><p>Fixed issue #22, the handling of the command identifier
924
arguments of <b class="cmd">critcl::ccommand</b>, <b class="cmd">critcl::cproc</b>, and
925
<b class="cmd">critcl::cdata</b>. We now properly allow any Tcl identifier
926
and generate proper internal C identifiers from them.</p>
927
<p>As part of this the signature of command <b class="cmd">critcl::name2c</b>
928
changed. The command now delivers a list of four values instead
929
of three. The new value was added at the end.</p>
930
<p>Further adapted the implementation of package
931
<b class="package"><a href="critcl_class.html">critcl::class</a></b>, a user of <b class="cmd">critcl::name2c</b>.
932
This package is now at version 1.0.6 and requires critcl 3.1.6</p>
933
<p>Lastly fixed the mis-handling of option <b class="option">-cname</b> in
934
<b class="cmd">critcl::ccommand</b>, and <b class="cmd">critcl::cproc</b>.</p></li>
935
<li><p>Fixed issue #23.</p></li>

<div id="section22" class="section"><h2><a name="section22">Changes for version 3.1.7</a></h2>
939
<ol class="enumerated">
940
<li><p>Fixed issue #24. Extract and unconditionally display compiler
941
warnings found in the build log. Prevents users from missing
942
warnings which, while not causing the build to fail, may
943
still indicate problems.</p></li>
944
<li><p>New feature. Output hook. All non-messaging user output is now
945
routed through the command <b class="cmd">critcl::print</b>, and users are
946
allowed to override it when using the critcl application-as-package.</p></li>
947
<li><p>New feature, by Ashok P. Nadkarni. Platform configurations can
948
inherit values from configurations defined before them.</p></li>

<div id="section24" class="section"><h2><a name="section24">Changes for version 3.1.9</a></h2>

<li><p>Fixed issue #28. Added missing -mXX flags for linking at the
964
linux-{32,64}-* targets.</p></li>
965
<li><p>Fixed issue #29. Replaced the use of raw "cheaders"
966
information in the processing of "cdefines" with the proper
967
include directives derived from it.</p></li>
968
<li><p>Fixed the issue behind rejected pull request #30 by Andrew
969
Shadura. Dynamically extract the stubs variable declarations
970
from the Tcl header files and generate matching variable
971
definitions for use in the package code. The generated code
972
will now be always consistent with the headers, even when
973
critcl's own copy of them is replaced by system headers.</p></li>
974
<li><p>Fixed issue #31. Accepted patch by Andrew Shadura, with
975
changes (comments), for easier integration of critcl with
976
OS package systems, replacing critcl's copies of Tcl headers
977
with their own.</p></li>
978
<li><p>Fixed issue #32. Merged pull request by Andrew Shadura.
979
Various typos in documentation and comments.</p></li>
980
<li><p>Fixed issue #33. Handle files starting with a dot better.</p></li>
