Its intended audience are developers working on critcl's internals\&. These commands are not needed to simply write a \fICriTcl script\fR\&. If you are in need of an overview of the whole system instead, please go and read the \fIIntroduction To CriTcl\fR\&. .PP This package resides in the Application Layer of CriTcl\&. .PP .PS .nf *================* |Applications | | critcl | | critcl::app | *================* +----------------+ |Core Packages | | critcl | | critcl::util | +----------------+ +----------------+ |Support Packages| | stubs::* | | md5, platform | | \&.\&.\&. | +----------------+ .fi .PE .PP , implementing the functionality of the \fICriTcl Application\fR, and through this, the mode \fBgenerate package\fR\&. The actual application is (only) a shim wrapping around this package\&. It itself is build on top of the core package \fBcritcl\fR\&. .SH API The package exports a single command .TP \fB::critcl::app::main\fR \fIcommandline\fR The \fIcommandline\fR is a list of zero or more options followed by zero or more \fICriTcl script\fR files\&. By default, the \fICriTcl script\fR files are build and the results cached\&. This cuts down on the time needed to load the package\&. The last occurrence of \fB-pkg\fR and \fB-tea\fR, if provided, selects the corresponding alternative mode of operations\&. For a larger set of examples please see section "Building CriTcl Packages" in the document about \fIUsing CriTcl\fR\&. .PP The options are: .SH OPTIONS The following options are understood: .TP \fB-v\fR .TP \fB--version\fR Print the version to \fBstdout\fR and exit\&. .TP \fB-I\fR path Arranges for the compiler to search \fIpath\fR for headers\&. Uses of this option are cumulative\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-L\fR path Arranges for the linker to search \fIpath\fR\&. Uses of this option are cumulative\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-cache\fR path Sets \fIpath\fR as the directory to use as the result cache\&. The default is "\fI~/\&.critcl/\fR", or "\fI~/\&.critcl/\&.\fR" when generating a package\&. See option \fB-pkg\fR, below\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-clean\fR Arranges for all files and directories in the result cache to be deleted before compilation begins\&. .sp Ignored when generating a package because this mode starts out with a unique and empty result cache\&. See option \fB-pkg\fR, below\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-config\fR path Provides a custom configuration file\&. By default a configuration included in the system core is used\&. When specified multiple times the last value is used\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-debug\fR mode Activates one of the following debugging modes: .RS .TP \fBmemory\fR Track and report memory allocations made by the Tcl core\&. .TP \fBsymbols\fR Compile all "\fI\&.c\fR" files with debugging symbols\&. .TP \fBall\fR Both \fBmemory\fR and \fBsymbols\fR\&. .RE .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. Uses of this option are cumulative\&. .TP \fB-disable\fR name Sets the value of the custom build configuration option \fIname\fR to \fBfalse\fR\&. It is equivalent to "-with-\fIname\fR 0"\&. .PP Validated only if one of the input files for the \fICriTcl script\fR actually defines and uses a custom build configuration option with that \fIname\fR\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-enable\fR name Sets the value of the custom build configuration option \fIname\fR to \fBtrue\fR\&. It is equivalent to "-with-\fIname\fR 1"\&. .PP Validated only if one of the input files for the \fICriTcl script\fR actually defines and uses a custom build configuration option with that \fIname\fR\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-force\fR Forces compilation even if a shared library for the file already exists\&. Unlike cleaning the cache, this is lazy in the destruction of files and only affects relevant files\&. .sp Ignored when generating a package (see option \fB-pkg\fR, below), which starts out with a unique and empty result cache\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-help\fR Prints a short description of command line syntax and options and then exits the application\&. .TP \fB-keep\fR Causes the system to cache compiled "\fI\&.c\fR" files\&. Also prevents the deletion of the unique result cache used by the run when generating a package (see option \fB-pkg\fR below), Intended for debugging of \fBcritcl\fR itself, where it may be necessary to inspect the generated C code\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-libdir\fR directory Adds \fIdirectory\fR to the list of directories the linker searches for libraries in (like \fB-L\fR)\&. With \fB-pkg\fR, generated packages are saved in \fIdirectory\fR\&. When specified multiple times the last value is used\&. The default is "\fIlib\fR", resolved relative to the current working directory\&. .TP \fB-includedir\fR directory Adds \fIdirectory\fR to the list of directories the compiler searches for headers in\&. With \fB-pkg\fR, generated header files are saved in \fIdirectory\fR\&. Uses of this option are cumulative\&. The last value is used as the destination for generated header files\&. The default is the relative directory "\fIinclude\fR", resolved relative to the current working directory\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-pkg\fR Generates a package from the \fICriTcl script\fR files\&. Input files are processed first as usual, but are then bundled into a single library, with additional generated files to form the library into a standard Tcl package\&. .sp generation\&. If both options, i\&.e\&. \fB-pkg\fR and \fB-tea\fR are specified the last one specified wins\&. .sp Options \fB-clean\fR and \fB-force\fR are ignored\&. \fB-libdir\fR is relevant in both this and \fB-tea\fR mode\&. .sp The basename of the first file is the name of the package to generate\&. If its file extension indicates a shared library ("\fI\&.so\fR", "\fI\&.sl\fR", "\fI\&.dylib\fR", and "\fI\&.dll\fR") it is also removed from the set of input files\&. Each \fICriTcl script\fR file is kept as part of the input\&. A single file without a suffix is assumed to be a \fICriTcl script\fR\&. A file without a suffix, but other input files following is treated like the name of a shared library proper, and removed from the set of input files\&. .sp Examples: .CS \&.\&.\&. -pkg \&.\&.\&. foo => Package name is: foo => Input file is: foo\&.tcl .CE .CS \&.\&.\&. -pkg \&.\&.\&. foo bar\&.tcl => Package name is: foo => Input file is: bar\&.tcl .CE .CS \&.\&.\&. -pkg \&.\&.\&. foo\&.tcl => Package name is: foo => Input file is: foo\&.tcl .CE .CS \&.\&.\&. -pkg \&.\&.\&. foo\&.so bar\&.tcl => Package name is: foo => Input file is: bar\&.tcl .CE .TP \fB-show\fR Prints the configuration of the chosen target to \fBstdout\fR and then exits\&. Set \fB-target\fR, below\&. .TP \fB-showall\fR Prints the whole chosen configuration file to \fBstdout\fR and then exits\&. See \fB-config\fR, above\&. .TP \fB-target\fR name Overrides the default choice of build target\&. Only the last occurrence of this option is used\&. The named target must exist in the chosen configuration file\&. Use \fB-targets\fR (see below) to get a list of the acceptable targets\&. Use \fB-config\fR to select the configuration file\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .TP \fB-targets\fR Prints the list of all known targets from the chosen configuration file to \fBstdout\fR and then exits\&. Use \fB-config\fR to select the configuration file\&. .TP \fB-tea\fR Like \fB-pkg\fR, except no binaries are generated\&. Creates a directory hierarchy containing the \fICriTcl script\fR, its companion files, and a TEA-conformant build system with most of the needed support code, including copies of the critcl packages\&. .sp If both \fB-pkg\fR and \fB-tea\fR are specified the last occurrence wins\&. .sp \fB-I\fR, \fB-L\fR, \fB-clean\fR, \fB-force\fR, \fB-cache\fR, \fB-includedir\fR, \fB-enable\fR, \fB-disable\fR, and \fB-with-\fBFOO\fR\fR are ignored\&. In contrast, the option \fB-libdir\fR is relevant in both this and \fB-pkg\fR mode\&. .sp The basename of the first file is the name of the package to generate\&. If its file extension indicates a shared library ("\fI\&.so\fR", "\fI\&.sl\fR", "\fI\&.dylib\fR", and "\fI\&.dll\fR") it is also removed from the set of input files\&. Each \fICriTcl script\fR file is kept as part of the input\&. A single file without a suffix is assumed to be a \fICriTcl script\fR\&. A file without a suffix, but other input files following is treated like the name of a shared library proper, and removed from the set of input files\&. .sp Examples: .CS \&.\&.\&. -tea \&.\&.\&. foo => Package name is: foo => Input file is: foo\&.tcl .CE .CS \&.\&.\&. -tea \&.\&.\&. foo bar\&.tcl => Package name is: foo => Input file is: bar\&.tcl .CE .CS \&.\&.\&. -tea \&.\&.\&. foo\&.tcl => Package name is: foo => Input file is: foo\&.tcl .CE .CS \&.\&.\&. -tea \&.\&.\&. foo\&.so bar\&.tcl => Package name is: foo => Input file is: bar\&.tcl .CE .TP \fB-with-\fBname\fR\fR value This option sets the value of the custom build configuration option \fIname\fR to \fIvalue\fR\&. .sp The information is validated only if one of the "\fI\&.critcl\fR" input files actually defines and uses a custom build configuration option with that \fIname\fR\&. .PP Ignored when generating a TEA package (see option \fB-tea\fR below)\&. .PP .SH "MODES OF OPERATION/USE" CriTcl can be used in three different modes of operation, called .IP [1] \fICompile & Run\fR, and .IP [2] \fIGenerate Package\fR .IP [3] \fIGenerate TEA Package\fR .PP \fICompile & Run\fR was the original mode and is the default for \fIcritcl_pkg\fR\&. Collects the C fragments from the \fICriTcl script\fR, builds them as needed, and caches the results to improve load times later\&. .PP The second mode, \fIGenerate Package\fR, was introduced to enable the creation of (prebuilt) deliverable packages which do not depend on the existence of a build system, i\&.e\&. C compiler, on the target machine\&. This was originally done through the experimental \fBCritbind\fR tool, and is now handled by the \fICriTcl Application\fR, also named \fBcritcl\fR\&. .PP Newly introduced with CriTcl version 3 is \fIGenerate TEA Package\fR\&. This mode constructs a directory hierarchy from the package which can later be built like a regular TEA package, i\&.e\&. using .CS \&.\&.\&./configure --prefix \&.\&.\&. make all isntall .CE .SH "PACKAGE STRUCTURE" Packages generated by critcl have the following basic structure: .CS +- pkgIndex\&.tcl +- critcl-rt\&.tcl +- license\&.terms (optional) | +- tcl (optional) | +- | +- +- .CE .PP \fINotes\fR .IP [1] The file "\fIpkgIndex\&.tcl\fR" is the standard package index file expected by Tcl's package management\&. It is sourced during a search for packages, and declares the package to Tcl with its files, and how to handle them\&. .IP [2] The file "\fIcritcl-rt\&.tcl\fR" is a helper file containing the common code used by "\fIpkgIndex\&.tcl\fR" to perform its tasks\&. .IP [3] The file "\fIlicense\&.terms\fR" is optional and appears only if the "\fI\&.critcl\fR" file the package is generated from used the command \fBcritcl::license\fR to declare package author and license\&. .IP [4] All files declared with the command \fBcritcl::tsources\fR are put into the sub-directory "\fItcl\fR"\&. .IP [5] The shared library generated by critcl is put into a platform-specific sub-directory\&. .PP .PP The whole structure, and especially the last point, enable us to later merge the results (for the same package, and version) for multiple target platforms into a single directory structure without conflict, by simply copying the top directories over each other\&. The only files which can conflict are in the and "\fItcl\fR" directories, and for these we know that they are identical across targets\&. The result of such a merge would look like: .CS +- pkgIndex\&.tcl +- critcl-rt\&.tcl +- license\&.terms (optional) | +- tcl (optional) | +- | +- | +- +- | +- \&.\&.\&. +- +- .CE .SH AUTHORS Jean Claude Wippler, Steve Landers, Andreas Kupries .SH "BUGS, IDEAS, FEEDBACK" This document, and the package it describes, will undoubtedly contain bugs and other problems\&.
