Valid +values are \fBc++98\fR, \fBc++11\fR (default), \fBc++14\fR, \fBc++17\fR, +\fBc++20\fR, and \fBc++23\fR\. + +The C++ standard affects various aspects of the generated code that are +discussed in more detail in various mapping-specific documentation\. Overall, +when C++11 is selected, the generated code relies on the move semantics and +uses \fBstd::unique_ptr\fR instead of deprecated \fBstd::auto_ptr\fR\. +Currently, there is no difference between the C++11 and the later standards +modes\. + +When the C++11 mode is selected, you normally don't need to perform any extra +steps other than enable C++11 in your C++ compiler, if required\. The XSD +compiler will automatically add the necessary macro defines to the generated +header files that will switch the header-only XSD runtime library +(\fBlibxsd\fR) to the C++11 mode\. However, if you include any of the XSD +runtime headers directly in your application (normally you just include the +generated headers), then you will need to define the \fBXSD_CXX11\fR macro for +your entire project\. +.IP "\fB--char-type\fR \fItype\fR" +Generate code using the provided character \fItype\fR instead of the default +\fBchar\fR\.

If +you pass \fBcustom\fR as the value then you will need to include the +transcoder implementation header for your encoding at the beginning of the +generated header files (see the \fB--hxx-prologue\fR option)\. + +For the \fBwchar_t\fR character type the only valid value is \fBauto\fR and +the encoding is automatically selected between UTF-16 and UTF-32/UCS-4, +depending on the \fBwchar_t\fR type size\. +.IP "\fB--output-dir\fR \fIdir\fR" +Write generated files to \fIdir\fR instead of the current directory\. +.IP "\fB--generate-inline\fR" +Generate simple functions inline\. This option triggers creation of the inline +file\. +.IP "\fB--generate-xml-schema\fR" +Generate a C++ header file as if the schema being compiled defines the XML +Schema namespace\. For the C++/Tree mapping, the resulting file will contain +definitions for all XML Schema built-in types\. For the C++/Parser mapping, +the resulting file will contain definitions for all the parser skeletons and +implementations corresponding to the XML Schema built-in types\. + +The schema file provided to the compiler need not exist and is only used to +derive the name of the resulting header file\.

The \fBXSD_NO_EXPORT\fR macro +can be used to omit this code during C++ compilation, which may be useful if +you would like to use the same generated code across multiple platforms\. +.IP "\fB--export-maps\fR" +Export polymorphism support maps from a Win32 DLL into which this generated +code is placed\. This is necessary when your type hierarchy is split across +several DLLs since otherwise each DLL will have its own set of maps\. In this +situation the generated code for the DLL which contains base types and/or +substitution group heads should be compiled with this option and the generated +code for all other DLLs should be compiled with \fB--import-maps\fR\. This +option is only valid together with \fB--generate-polymorphic\fR\. The +\fBXSD_NO_EXPORT\fR macro can be used to omit this code during C++ +compilation, which may be useful if you would like to use the same generated +code across multiple platforms\. +.IP "\fB--import-maps\fR" +Import polymorphism support maps to a Win32 DLL or executable into which this +generated code is linked\.

This option triggers the creation +of the \fB\.d\fR file containing the dependencies of the generated files on +the main schema file as well as all the schema files that it includes/imports, +transitively\. This dependency file is then normally included into the main +\fBmakefile\fR to implement automatic dependency tracking\. See also the +\fB--dep-*\fR options\. + +Note also that automatic dependency generation is not supported in the +file-per-type mode (\fB--file-per-type\fR)\. In this case, all the generated +files are produced with a single compiler invocation and depend on all the +schemas\. As a result, it is easier to establish such a dependency manually, +perhaps with the help of the \fB--file-list*\fR options\. +.IP "\fB--generate-dep-only\fR" +Generate \fBmake\fR dependency information only\. +.IP "\fB--dep-phony\fR" +Generate phony targets for included/imported schema files, causing each to +depend on nothing\. Such dummy rules work around \fBmake\fR errors caused by +the removal of schema files without also updating the dependency file to +match\. +.IP "\fB--dep-target\fR \fItarget\fR" +Change the target of the dependency rule\.

Each option should appearing on a +separate line optionally followed by space and an option value\. Empty lines +and lines starting with \fB#\fR are ignored\. Option values can be enclosed in +double (\fB"\fR) or single (\fB'\fR) quotes to preserve leading and trailing +whitespaces as well as to specify empty values\. If the value itself contains +trailing or leading quotes, enclose it with an extra pair of quotes, for +example \fB'"x"'\fR\. Non-leading and non-trailing quotes are interpreted as +being part of the option value\. + +The semantics of providing options in a file is equivalent to providing the +same set of options in the same order on the command line at the point where +the \fB--options-file\fR option is specified except that the shell escaping +and quoting is not required\.

This +mechanism can be useful if you are using a custom character encoding and some +of the strings in your schemas, for example element/attribute names or +enumeration values, contain non-ASCII characters\. In this case you will need +to provide a custom mapping to C++ literals for such strings\. The format of +this file is specified in the \fBcustom-literals\.xsd\fR XML Schema file that +can be found in the documentation directory\. +.IP "\fB--preserve-anonymous\fR" +Preserve anonymous types\. By default anonymous types are automatically named +with names derived from the enclosing elements/attributes\. Because mappings +implemented by this compiler require all types to be named, this option is +only useful if you want to make sure your schemas don't have anonymous types\. +.IP "\fB--show-anonymous\fR" +Show elements and attributes that are of anonymous types\. This option only +makes sense together with the \fB--preserve-anonymous\fR option\. +.IP "\fB--anonymous-regex\fR \fIregex\fR" +Add \fIregex\fR to the list of regular expressions used to derive names for +anonymous types from the enclosing attributes/elements\. \fIregex\fR is a +Perl-like regular expression in the form +\fB/\fR\fIpattern\fR\fB/\fR\fIreplacement\fR\fB/\fR\fR\. Any character can be +used as a delimiter instead of '\fB/\fR'\. Escaping of the delimiter character +in \fIpattern\fR or \fIreplacement\fR is not supported\. + +All the regular expressions are pushed into a stack with the last specified +expression considered first\.

For example, if you use " " for quoting you will get +a wrong result with POSIX shells if your expression contains $. The +standard way of dealing with this on POSIX systems is to use ' ' +instead. Unfortunately, Windows shell does not remove ' ' from +arguments when they are passed to applications. As a result you may +have to use ' ' for POSIX and " " for Windows ($ is not treated as +a special character on Windows). + +Alternatively, you can save regular expression options into a file, +one option per line, and use this file with the +.B --options-file +option. With this approach you don't need to worry about shell quoting. + +.\" +.\" DIAGNOSTICS +.\" +.SH DIAGNOSTICS +If the input file is not a valid W3C XML Schema definition, +.B xsd +will issue diagnostic messages to +.B STDERR +and exit with non-zero exit code. +.SH BUGS +Send bug reports to the xsd-users@codesynthesis.com mailing list. +.SH COPYRIGHT +Copyright (c) 2005-2023 Code Synthesis. + +Permission is granted to copy, distribute and/or modify this +document under the terms of the GNU Free Documentation License, +version 1.2; with no Invariant Sections, no Front-Cover Texts and +no Back-Cover Texts.
