The optimizer avoids removing, moving, or duplicating calls to such functions. This is the default behavior for \texttt{transaction}-based types. \item \texttt{exe FILENAME} sets the filename to which to write the output executable. The default for file \texttt{P.urp} is \texttt{P.exe}. \item \texttt{ffi FILENAME} reads the file \texttt{FILENAME.urs} to determine the interface to a new FFI module. The name of the module is calculated from \texttt{FILENAME} in the same way as for normal source files. See the files \texttt{include/urweb/urweb\_cpp.h} and \texttt{src/c/urweb.c} for examples of C headers and implementations for FFI modules. In general, every type or value \texttt{Module.ident} becomes \texttt{uw\_Module\_ident} in C. +\item \texttt{html5} activates work-in-progress support for generating HTML5 instead of XHTML. For now, this option only affects the first few tokens on any page, which are always the same. \item \texttt{include FILENAME} adds \texttt{FILENAME} to the list of files to be \texttt{\#include}d in C sources. This is most useful for interfacing with new FFI modules. \item \texttt{jsFunc Module.ident=name} gives the JavaScript name of an FFI value. \item \texttt{library FILENAME} parses \texttt{FILENAME.urp} and merges its contents with the rest of the current file's contents. If \texttt{FILENAME.urp} doesn't exist, the compiler also tries \texttt{FILENAME/lib.urp}. diff --git a/include/urweb/types_cpp.h b/include/urweb/types_cpp.h index 789aecb1..cd80b0e7 100644 --- a/include/urweb/types_cpp.h +++ b/include/urweb/types_cpp.h @@ -102,6 +102,8 @@ typedef struct { uw_periodic *periodics; // 0-terminated array uw_Basis_string time_format; + + int is_html5; } uw_app; #define ERROR_BUF_LEN 1024 diff --git a/include/urweb/urweb_cpp.h b/include/urweb/urweb_cpp.h index 248e54e4..1943a9f9 100644 --- a/include/urweb/urweb_cpp.h +++ b/include/urweb/urweb_cpp.h @@ -377,4 +377,6 @@ uw_Basis_string uw_Basis_fieldValue(struct uw_context *, uw_Basis_postField); uw_Basis_string uw_Basis_remainingFields(struct uw_context *, uw_Basis_postField); uw_Basis_postField *uw_Basis_firstFormField(struct uw_context *, uw_Basis_string); +extern const char uw_begin_xhtml[], uw_begin_html5[]; + #endif diff --git a/src/c/urweb.c b/src/c/urweb.c index 3a5933c5..c0c339c1 100644 --- a/src/c/urweb.c +++ b/src/c/urweb.c @@ -3241,7 +3241,8 @@ int uw_rollback(uw_context ctx, int will_retry) { return 0; } -static const char begin_xhtml[] = "\n\n"; +const char uw_begin_xhtml[] = "\n\n"; +const char uw_begin_html5[] = ""; extern int uw_hash_blocksize; @@ -3331,11 +3332,14 @@ int uw_commit(uw_context ctx) { uw_check(ctx, 1); *ctx->page.front = 0; - if (!ctx->returning_indirectly && !strncmp(ctx->page.start, begin_xhtml, sizeof begin_xhtml - 1)) { + if (!ctx->returning_indirectly + && (ctx->app->is_html5 + ? !strncmp(ctx->page.start, uw_begin_html5, sizeof uw_begin_html5 - 1) + : !strncmp(ctx->page.start, uw_begin_xhtml, sizeof uw_begin_xhtml - 1))) { char *s; // Splice script data into appropriate part of page, also adding if needed. - s = ctx->page.start + sizeof begin_xhtml - 1; + s = ctx->page.start + (ctx->app->is_html5 ? sizeof uw_begin_html5 - 1 : sizeof uw_begin_xhtml - 1); s = strchr(s, '<'); if (s == NULL) { // Weird.
