\fBTcl_ExternalToUtf\fR.
.PP
\fBTcl_WinUtfToTChar\fR and \fBTcl_WinTCharToUtf\fR are
Windows-only convenience
functions for converting between UTF-8 and Windows strings
based on the TCHAR type which is by convention
a Unicode character on Windows NT.




.PP
\fBTcl_GetEncodingName\fR is roughly the inverse of \fBTcl_GetEncoding\fR.
Given an \fIencoding\fR, the return value is the \fIname\fR argument that
was used to create the encoding.  The string returned by
\fBTcl_GetEncodingName\fR is only guaranteed to persist until the
\fIencoding\fR is deleted.  The caller must not modify this string.
.PP

\fBincr x\fR
.CE
.PP
The \fBincr\fR command first gets an integer from \fIx\fR's value
by calling \fBTcl_GetIntFromObj\fR.
This procedure checks whether the value is already an integer value.
Since it is not, it converts the value
by setting the value's internal representation
to the integer \fB123\fR
and setting the value's \fItypePtr\fR
to point to the integer Tcl_ObjType structure.
Both representations are now valid.
\fBincr\fR increments the value's integer internal representation
then invalidates its string representation
(by calling \fBTcl_InvalidateStringRep\fR)

value may then be passed back to one of \fBTcl_RestoreInterpState\fR
or \fBTcl_DiscardInterpState\fR, depending on whether the interp
state is to be restored.  So long as one of the latter two routines
is called, Tcl will take care of memory management.
.PP
The second triplet stores the snapshot of only the interpreter
result (not its complete state) in memory allocated by the caller.
These routines are passed a pointer to \fBTcl_SavedResult\fR
that is used to store enough information to restore the interpreter result.
\fBTcl_SavedResult\fR can be allocated on the stack of the calling
procedure.  These routines do not save the state of any error
information in the interpreter (e.g. the \fB\-errorcode\fR or
\fB\-errorinfo\fR return options, when an error is in progress).
.PP
Because the routines \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
a superset of the functions provided by the other routines,

\fBTcl_UtfToLower\fR(\fIstr\fR)
.sp
int
\fBTcl_UtfToTitle\fR(\fIstr\fR)
.SH ARGUMENTS
.AS char *str in/out
.AP int ch in
The Unicode character to be converted.
.AP char *str in/out
Pointer to UTF-8 string to be converted in place.
.BE

.SH DESCRIPTION
.PP
The first three routines convert the case of individual Unicode characters:

\fBTcl_UniCharIsUpper\fR(\fIch\fR)
.sp
int
\fBTcl_UniCharIsWordChar\fR(\fIch\fR)
.SH ARGUMENTS
.AS int ch
.AP int ch in
The Unicode character to be examined.
.BE

.SH DESCRIPTION
.PP
All of the routines described examine Unicode characters and return a
boolean value. A non-zero return value means that the character does
belong to the character class associated with the called routine. The
rest of this document just describes the character classes associated
with the various routines.




.SH "CHARACTER CLASSES"
.PP
\fBTcl_UniCharIsAlnum\fR tests if the character is an alphanumeric Unicode character.
.PP
\fBTcl_UniCharIsAlpha\fR tests if the character is an alphabetic Unicode character.
.PP

\fBTcl_UtfBackslash\fR(\fIsrc, readPtr, dst\fR)
.SH ARGUMENTS
.AS "const Tcl_UniChar" *uniPattern in/out
.AP char *buf out
Buffer in which the UTF-8 representation of the Tcl_UniChar is stored.  At most
\fBTCL_UTF_MAX\fR bytes are stored in the buffer.
.AP int ch in
The Unicode character to be converted or examined.
.AP Tcl_UniChar *chPtr out
Filled with the Tcl_UniChar represented by the head of the UTF-8 string.
.AP "const char" *src in
Pointer to a UTF-8 string.
.AP "const char" *cs in
Pointer to a UTF-8 string.
.AP "const char" *ct in

The variable \fBtcl_prompt2\fR is used in a similar way when
a newline is typed but the current command is not yet complete;
if \fBtcl_prompt2\fR is not set then no prompt is output for
incomplete commands.
.SH "STANDARD CHANNELS"
.PP
See \fBTcl_StandardChannels\fR for more explanations.
.SH ZIPVFS
.PP
When a zipfile is concatenated to the end of a \fBtclsh\fR, on
startup the contents of the zip archive will be mounted as the
virtual file system /zvfs. If a top level directory tcl8.6 is
present in the zip archive, it will become the directory loaded
as env(TCL_LIBRARY). If a file named \fBmain.tcl\fR is present
in the top level directory of the zip archive, it will be sourced
instead of the shell's normal command line handing.

\fBTclZipfs_AppHook()\fR is a utility function to perform standard
application initialization procedures. If the current application has
a mountable zip file system, that file system is mounted under \fIZIPROOT\fR\fB/app\fR.
If a file named \fBmain.tcl\fR is located in that file system, it is treated
as the startup script for the process. If the file \fIZIPROOT\fR\fB/app/tcl_library/init.tcl\fR
is present, \fBtcl_library\fR is set to  \fIZIPROOT\fR\fB/app/tcl_library.
.PP
If the \fBtcl_library\fR was not found in the application, the system will then search for it
as either a VFS attached to the application dynamic library, or as a zip archive named
libtcl_\fIMAJOR\fR_\fIMINOR\fR_\fIpatchLevel\fR.zip either in the present working directory
or in the standard tcl install location.
.PP
\fBTclzipfs_Mount()\fR mount the ZIP archive \fIzipname\fR on the mount
point given in \fImntpt\fR using the optional ZIP password \fIpasswd\fR.
Errors during that process are reported in the interpreter \fIinterp\fR.
If \fImountpoint\fR is a NULL pointer, information on all currently mounted
ZIP file systems is written into \fIinterp\fR's result as a sequence of
mount points and ZIP file names.
.PP
\fBTclzipfs_Unmount()\fR undoes the effect of \fBTclzipfs_Mount()\fR,
i.e. it unmounts the mounted ZIP file system at \fImountpoint\fR. Errors are
reported in the interpreter \fIinterp\fR.

.SH DESCRIPTION
.PP
The \fBzipfs\fR package provides tcl with the ability to mount
the contents of a zip file as a virtual file system.
.TP
\fBzipfs exists\fR \fIfilename\fR
.
Return 1 if the given filename exists in the mounted zipfs and 0 if it does not.
.TP
\fBzipfs find\fR \fIdir\fR
.
Recursively lists files including and below the directory \fIdir\fR.
The result list consists of relative path names starting from the
given directory. This command is also used by the \fBzipfs mkzip\fR
and \fBzipfs mkimg\fR commands.
.TP
\fBzipfs info\fR \fIfile\fR
.
Return information about the given file in the mounted zipfs.  The information
consists of (1) the name of the ZIP archive file that contains the file,
(2) the size of the file after decompressions, (3) the compressed size of
the file, and (4) the offset of the compressed data in the ZIP archive file.
.RS
.PP
Note: querying the mount point gives the start of zip data offset in (4),
which can be used to truncate the zip info off an executable.
.RE
.TP
\fBzipfs list\fR \fB?(-glob|-regexp)?\fR \fI?pattern?\fR
.
Return a list of all files in the mounted zipfs.  The order of the names
in the list is arbitrary.
.TP
\fBzipfs mkimg\fR \fIoutfile\fR \fIindir\fR \fI?strip?\fR \fI?password?\fR \fI?infile?\fR
.
Creates an image (potentially a new executable file) similar to
\fBzipfs mkzip\fR. If the \fIinfile\fR parameter is specified,
this file is prepended in front of the ZIP archive, otherwise the file
returned by \fBTcl_NameOfExecutable(3)\fR (i.e. the executable file of
the running process) is used. If the \fIpassword\fR parameter is not empty,
an obfuscated version of that password is placed between the image and ZIP
chunks of the output file and the contents of the ZIP chunk are protected
with that password.
.RS
.PP
Caution: highly experimental, not usable on Android, only partially tested
on Linux and Windows.
.RE
.TP
\fBzipfs mkkey\fR \fIpassword\fR
.
For the clear text \fIpassword\fR argument an obfuscated string version
is returned with the same format used in the \fBzipfs mkimg\fR command.
.TP
\fBzipfs mkzip\fR \fIoutfile\fR \fIindir\fR \fI?strip?\fR \fI?password?\fR
.
Creates a ZIP archive file named \fIoutfile\fR from the contents of the input
directory \fIindir\fR (contained regular files only) with optional ZIP
password \fIpassword\fR. While processing the files below \fIindir\fR the
optional file name prefix given in \fIstrip\fR is stripped off the beginning
of the respective file name.
.RS
.PP
Caution: the choice of the \fIindir\fR parameter
(less the optional stripped prefix) determines the later root name of the
archive's content.
.RE
.TP
\fBzipfs mount ?\fImountpoint\fR? ?\fIzipfile\fR? ?\fIpassword\fR?
.
The \fBzipfs mount\fR command mounts a ZIP archive file as a VFS.
After this command executes, files contained in \fIzipfile\fR
will appear to Tcl to be regular files at the mount point.
.RS
.PP
With no \fIzipfile\fR, returns the zipfile mounted at \fImountpoint\fR.
With no \fImountpoint\fR, return all zipfile/mount pairs.
If \fImountpoint\fR is specified as an empty string, mount on file path.
.RE
.TP
\fBzipfs root\fR
Returns a constant string which indicates the mount point for zipfs volumes
for the current platform. On Windows, this value is zipfs:/. On Unux, //zipfs:/
.RE
.TP
\fBzipfs unmount \fImountpoint\fR
.
Unmounts a previously mounted ZIP archive mounted to \fImountpoint\fR.
