jan.nijtmans bea160e7f6 Start building this branch with Travis. See how far we get 2018-11-01 20:18:12 +00:00
dgp a0c7ff582a Eliminate fallback attempts when broken strtod() routines are detected.
This has long been creating more problems than it solves.
2018-11-01 14:46:07 +00:00
jan.nijtmans b3dceb5360 Make MacOSX compile work (hopefully) and cross-compile on mingw-w64 (compile only, no unit-test yet) 2018-10-31 21:02:42 +00:00

README: Tcl
This is the Tcl 8.7a2 source distribution.
http://sourceforge.net/projects/tcl/files/Tcl/
You can get any source release of Tcl from the URL above.
Contents
--------
1. Introduction
2. Documentation
3. Compiling and installing Tcl
4. Development tools
5. Tcl newsgroup
6. The Tcler's Wiki
7. Mailing lists
8. Support and Training
9. Tracking Development
10. Thank You
1. Introduction
---------------
Tcl provides a powerful platform for creating integration applications that
tie together diverse applications, protocols, devices, and frameworks.
When paired with the Tk toolkit, Tcl provides the fastest and most powerful
way to create GUI applications that run on PCs, Unix, and Mac OS X.
Tcl can also be used for a variety of web-related tasks and for creating
powerful command languages for applications.
Tcl is maintained, enhanced, and distributed freely by the Tcl community.
Source code development and tracking of bug reports and feature requests
takes place at:
http://core.tcl.tk/
Tcl/Tk release and mailing list services are hosted by SourceForge:
http://sourceforge.net/projects/tcl/
with the Tcl Developer Xchange hosted at:
http://www.tcl.tk/
Tcl is a freely available open source package. You can do virtually
anything you like with it, such as modifying it, redistributing it,
and selling it either in whole or in part. See the file
"license.terms" for complete information.
2. Documentation
----------------
Extensive documentation is available at our website.
The home page for this release, including new features, is
http://www.tcl.tk/software/tcltk/8.7.html
Detailed release notes can be found at the file distributions page
by clicking on the relevant version.
http://sourceforge.net/projects/tcl/files/Tcl/
Information about Tcl itself can be found at
http://www.tcl.tk/about/
There have been many Tcl books on the market. Many are mentioned in the Wiki:
http://wiki.tcl.tk/_/ref?N=25206
To view the complete set of reference manual entries for Tcl 8.7 online,
visit the URL:
http://www.tcl.tk/man/tcl8.7/
2a. Unix Documentation
----------------------
The "doc" subdirectory in this release contains a complete set of
reference manual entries for Tcl. Files with extension ".1" are for
programs (for example, tclsh.1); files with extension ".3" are for C
library procedures; and files with extension ".n" describe Tcl
commands. The file "doc/Tcl.n" gives a quick summary of the Tcl
language syntax. To print any of the man pages on Unix, cd to the
"doc" directory and invoke your favorite variant of troff using the
normal -man macros, for example
ditroff -man Tcl.n
to print Tcl.n. If Tcl has been installed correctly and your "man" program
supports it, you should be able to access the Tcl manual entries using the
normal "man" mechanisms, such as
man Tcl
2b. Windows Documentation
-------------------------
The "doc" subdirectory in this release contains a complete set of Windows
help files for Tcl. Once you install this Tcl release, a shortcut to the
Windows help Tcl documentation will appear in the "Start" menu:
Start | Programs | Tcl | Tcl Help
3. Compiling and installing Tcl
-------------------------------
There are brief notes in the unix/README, win/README, and macosx/README about
compiling on these different platforms. There is additional information
about building Tcl from sources at
http://www.tcl.tk/doc/howto/compile.html
4. Development tools
---------------------------
ActiveState produces a high quality set of commercial quality development
tools that is available to accelerate your Tcl application development.
Tcl Dev Kit builds on the earlier TclPro toolset and provides a debugger,
static code checker, single-file wrapping utility, bytecode compiler and
more. More information can be found at
http://www.ActiveState.com/Tcl
5. Tcl newsgroup
----------------
There is a USENET news group, "comp.lang.tcl", intended for the exchange of
information about Tcl, Tk, and related applications. The newsgroup is a
great place to ask general information questions. For bug reports, please
see the "Support and bug fixes" section below.
6. Tcl'ers Wiki
---------------
A Wiki-based open community site covering all aspects of Tcl/Tk is at:
http://wiki.tcl.tk/
It is dedicated to the Tcl programming language and its extensions. A
wealth of useful information can be found there. It contains code
snippets, references to papers, books, and FAQs, as well as pointers to
development tools, extensions, and applications. You can also recommend
additional URLs by editing the wiki yourself.
7. Mailing lists
----------------
Several mailing lists are hosted at SourceForge to discuss development or
use issues (like Macintosh and Windows topics). For more information and
to subscribe, visit:
http://sourceforge.net/projects/tcl/
and go to the Mailing Lists page.
8. Support and Training
------------------------
We are very interested in receiving bug reports, patches, and suggestions
for improvements. We prefer that you send this information to us as
tickets entered into our tracker at:
http://core.tcl.tk/tcl/reportlist
We will log and follow-up on each bug, although we cannot promise a
specific turn-around time. Enhancements may take longer and may not happen
at all unless there is widespread support for them (we're trying to
slow the rate at which Tcl/Tk turns into a kitchen sink). It's very
difficult to make incompatible changes to Tcl/Tk at this point, due to
the size of the installed base.
The Tcl community is too large for us to provide much individual support
for users. If you need help we suggest that you post questions to
comp.lang.tcl. We read the newsgroup and will attempt to answer esoteric
questions for which no one else is likely to know the answer. In addition,
see the following Web site for links to other organizations that offer
Tcl/Tk training:
http://wiki.tcl.tk/training
9. Tracking Development
-----------------------
Tcl is developed in public. To keep an eye on how Tcl is changing, see
http://core.tcl.tk/
10. Thank You
-------------
We'd like to express our thanks to the Tcl community for all the
helpful suggestions, bug reports, and patches we have received.
Tcl/Tk has improved vastly and will continue to do so with your help.

\fBTcl_RegisterCommandTypeName\fR is used to associate a name (the
\fItypeName\fR argument) with a particular implementation function so that it
can then be looked up with \fBTcl_GetCommandTypeName\fR, which in turn is
called with a command token that information is wanted for and which returns
the name of the type that was registered for the implementation function used
for that command. (The lookup functionality is surfaced virtually directly in Tcl via
\fBinfo cmdtype\fR.) If there is no function registered for a particular
function, the result will be the string literal
.QW \fBnative\fR .
The registration of a name can be undone by registering a mapping to NULL
instead. The result from \fBTcl_GetCommandTypeName\fR will be exactly that
string which was registered, and not a copy; use of a compile-time constant
string is \fIstrongly recommended\fR.

.SH DESCRIPTION
.PP
These routines save the state of an interpreter before a call to a routine such
as \fBTcl_Eval\fR, and restore the state afterwards.
These routines allows a C procedure to take a snapshot of the current
state of an interpreter so that it can be restored after a call
to \fBTcl_Eval\fR or some other routine that modifies the interpreter
state. There are two triplets of routines meant to work together.
.PP
\fBTcl_SaveInterpState\fR saves the parts of \fIinterp\fR that comprise the
result of a script, including the resulting value, the return code passed as
\fIstatus\fR, and any options such as \fB\-errorinfo\fR and \fB\-errorcode\fR.
It returns a token for the saved state. The interpreter result is not reset
and no interpreter state is changed.
The first triplet stores the snapshot of interpreter state in
an opaque token returned by \fBTcl_SaveInterpState\fR. That token
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
\fBTcl_RestoreInterpState\fR restores the state indicated by \fIstate\fR and
returns the \fIstatus\fR originally passed in the corresponding call to
\fBTcl_SaveInterpState\fR.
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
If a saved state is not restored, \fBTcl_DiscardInterpState\fR must be called
to release it. A token used to discard or restore state must not be used
again.
Because the routines \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
a superset of the functions provided by the other routines,
any new code should only make use of the more powerful routines.
The older, weaker routines \fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR,
and \fBTcl_DiscardResult\fR continue to exist only for the sake
of existing programs that may already be using them.
.PP
\fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR, and \fBTcl_DiscardResult\fR are
deprecated. Instead use \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR, which are more
capable.
\fBTcl_SaveInterpState\fR takes a snapshot of those portions of
interpreter state that make up the full result of script evaluation.
This include the interpreter result, the return code (passed in
as the \fIstatus\fR argument, and any return options, including
\fB\-errorinfo\fR and \fB\-errorcode\fR when an error is in progress.
This snapshot is returned as an opaque token of type \fBTcl_InterpState\fR.
The call to \fBTcl_SaveInterpState\fR does not itself change the
state of the interpreter. Unlike \fBTcl_SaveResult\fR, it does
not reset the interpreter.
.PP
\fBTcl_SaveResult\fR moves the result of \fIinterp\fR to the location
\fIstatePtr\fR points to and returns the interpreter result to its initial
state. It does not save options such as \fB\-errorcode\fR or
\fB\-errorinfo\fR.
\fBTcl_RestoreInterpState\fR accepts a \fBTcl_InterpState\fR token
previously returned by \fBTcl_SaveInterpState\fR and restores the
state of the interp to the state held in that snapshot. The return
value of \fBTcl_RestoreInterpState\fR is the status value originally
passed to \fBTcl_SaveInterpState\fR when the snapshot token was
created.
.PP
\fBTcl_RestoreResult\fR clears any existing result or error in \fIinterp\fR and
moves the result from \fIstatePtr\fR back to \fIinterp\fR. \fIstatePtr\fR is
then in an undefined state and must not be used until passed again to
\fBTcl_DiscardInterpState\fR is called to release a \fBTcl_InterpState\fR
token previously returned by \fBTcl_SaveInterpState\fR when that
snapshot is not to be restored to an interp.
.PP
The \fBTcl_InterpState\fR token returned by \fBTcl_SaveInterpState\fR
must eventually be passed to either \fBTcl_RestoreInterpState\fR
or \fBTcl_DiscardInterpState\fR to avoid a memory leak. Once
the \fBTcl_InterpState\fR token is passed to one of them, the
token is no longer valid and should not be used anymore.
.PP
\fBTcl_SaveResult\fR moves the string and value results
of \fIinterp\fR into the location specified by \fIstatePtr\fR.
\fBTcl_SaveResult\fR clears the result for \fIinterp\fR and
leaves the result in its normal empty initialized state.
.PP
\fBTcl_RestoreResult\fR moves the string and value results from
\fIstatePtr\fR back into \fIinterp\fR. Any result or error that was
already in the interpreter will be cleared. The \fIstatePtr\fR is left
in an uninitialized state and cannot be used until another call to
\fBTcl_SaveResult\fR.
.PP
\fBTcl_DiscardResult\fR releases the state stored at \fBstatePtr\fR, which is
then in an undefined state and must not be used until passed again to
\fBTcl_DiscardResult\fR releases the saved interpreter state
stored at \fBstatePtr\fR. The state structure is left in an
uninitialized state and cannot be used until another call to
\fBTcl_SaveResult\fR.
.PP
If a saved result is not restored, \fBTcl_DiscardResult\fR must be called to
release it.
Once \fBTcl_SaveResult\fR is called to save the interpreter
result, either \fBTcl_RestoreResult\fR or
\fBTcl_DiscardResult\fR must be called to properly clean up the
memory associated with the saved state.

.SH NAME
oo::abstract \- a class that does not allow direct instances of itself
.SH SYNOPSIS

.fi
.SH "CLASS HIERARCHY"
.nf
\fBoo::object\fR
\(-> \fBoo::class\fR
\(-> \fBoo::abstract\fR
.fi
.BE
.SH DESCRIPTION
Abstract classes are classes that can contain definitions, but which cannot be
directly manufactured; they are intended to only ever be inherited from and
instantiated indirectly. The characteristic methods of \fBoo::class\fR
(\fBcreate\fR and \fBnew\fR) are not exported by an instance of
\fBoo::abstract\fR.
.PP
Note that \fBoo::abstract\fR is not itself an instance of \fBoo::abstract\fR.
.SS CONSTRUCTOR
The \fBoo::abstract\fR class does not define an explicit constructor; this
means that it is effectively the same as the constructor of the
\fBoo::class\fR class.
.SS DESTRUCTOR
The \fBoo::abstract\fR class does not define an explicit destructor;
destroying an instance of it is just like destroying an ordinary class (and
will destroy all its subclasses).
.SS "EXPORTED METHODS"
The \fBoo::abstract\fR class defines no new exported methods.
.SS "NON-EXPORTED METHODS"
The \fBoo::abstract\fR class explicitly states that \fBcreate\fR,
\fBcreateWithNamespace\fR, and \fBnew\fR are unexported.
.SH EXAMPLES
.PP
This example defines a simple class hierarchy and creates a new instance of
it. It then invokes a method of the object before destroying the hierarchy and
showing that the destruction is transitive.

script fragment that will invoke the method, \fImethodName\fR, on the current
object (as reported by \fBself\fR) when executed. Any additional arguments
provided will be provided as leading arguments to the callback. The resulting
script fragment shall be a proper list.
.PP
Note that it is up to the caller to ensure that the current object is able to
handle the call of \fImethodName\fR; this command does not check that.
\fImethodName\fR may refer to any exported or unexported method, but may not
refer to a private method as those can only be invoked directly from within
methods. If there is no such method present at the point when the callback is
invoked, the standard \fBunknown\fR method handler will be called.
.SH EXAMPLE
This is a simple echo server class. The \fBcallback\fR command is used in two
places, to arrange for the incoming socket connections to be handled by the
\fIAccept\fR method, and to arrange for the incoming bytes on those
connections to be handled by the \fIReceive\fR method.

The \fBclassvariable\fR command is available within methods. It takes a series
of one or more variable names and makes them available in the method's scope;
those variable names must not be qualified and must not refer to array
elements. The originating scope for the variables is the namespace of the
class that the method was defined by. In other words, the referenced variables
are shared between all instances of that class.

Note: This command is equivalent to the command \fBtypevariable\fR provided by
the snit package in tcllib for approximately the same purpose. If used in a
method defined directly on a class instance (e.g., through the
\fBoo::objdefine\fR \fBmethod\fR definition) this is very much like just

Tcl expressions differ from C expressions in the way that

non-numeric operands and string comparisons, as well as some
additional operators not found in C.
.PP
When an expression evaluates to an integer, the value is the decimal form of
the integer, and when an expression evaluates to a floating-point number, the
value is the form produced by the \fB%g\fR format specifier of Tcl's
\fBformat\fR command.
.SS OPERANDS
.PP
An expression consists of a combination of operands, operators, parentheses and
commas, possibly with whitespace between any of these elements, which is
ignored.
An integer operand may be specified in decimal (the normal case, the optional
first two characters are \fB0d\fR), binary
(the first two characters are \fB0b\fR), octal
(the first two characters are \fB0o\fR), or hexadecimal
(the first two characters are \fB0x\fR) form. For
compatibility with older Tcl releases, an operand that begins with \fB0\fR is
interpreted as an octal integer even if the second character is not \fBo\fR.
A floating-point number may be specified in any of several
common decimal formats, and may use the decimal point \fB.\fR,
\fBe\fR or \fBE\fR for scientific notation, and
the sign characters \fB+\fR and \fB\-\fR. The
following are all valid floating-point numbers: 2.1, 3., 6e4, 7.91e+16.
The strings \fBInf\fR
and \fBNaN\fR, in any combination of case, are also recognized as floating point
values. An operand that doesn't have a numeric interpretation must be quoted
with either braces or with double quotes.
A Tcl expression consists of a combination of operands, operators,
parentheses and commas.
White space may be used between the operands and operators and
parentheses (or commas); it is ignored by the expression's instructions.
Where possible, operands are interpreted as integer values.
Integer values may be specified in decimal (the normal case), in binary
(if the first two characters of the operand are \fB0b\fR), in octal
(if the first two characters of the operand are \fB0o\fR), or in hexadecimal
(if the first two characters of the operand are \fB0x\fR). For
compatibility with older Tcl releases, an octal integer value is also
indicated simply when the first character of the operand is \fB0\fR,
whether or not the second character is also \fBo\fR.
If an operand does not have one of the integer formats given
above, then it is treated as a floating-point number if that is
possible. Floating-point numbers may be specified in any of several
common formats making use of the decimal digits, the decimal point \fB.\fR,
the characters \fBe\fR or \fBE\fR indicating scientific notation, and
the sign characters \fB+\fR or \fB\-\fR. For example, all of the
following are valid floating-point numbers: 2.1, 3., 6e4, 7.91e+16.
Also recognized as floating point values are the strings \fBInf\fR
and \fBNaN\fR making use of any case for each character.
If no numeric interpretation is possible (note that all literal
operands that are not numeric or boolean must be quoted with either
braces or with double quotes), then an operand is left as a string
(and only a limited set of operators may be applied to it).

.PP
Because \fBexpr\fR parses and performs substitutions on values that have
already been parsed and substituted by \fBTcl\fR, it is usually best to enclose
expressions in braces to avoid the first round of substitutions by
\fBTcl\fR.
Where the above substitutions occur (e.g. inside quoted strings), they
are performed by the expression's instructions.
However, the command parser may already have performed one round of
substitution before the expression processor was called.
As discussed below, it is usually best to enclose expressions
in braces to prevent the command parser from performing substitutions
on the contents.

.SS OPERATORS
.PP
For operators having both a numeric mode and a string mode, the numeric mode is
chosen when all operands have a numeric interpretation. The integer
interpretation of an operand is preferred over the floating-point
interpretation. To ensure string operations on arbitrary values it is generally a
good idea to use \fBeq\fR, \fBne\fR, or the \fBstring\fR command instead of
more versatile operators such as \fB==\fR.
.PP
Unless otherwise specified, operators accept non-numeric operands. The value
of a boolean operation is 1 if true, 0 otherwise. See also \fBstring is\fR
\fBboolean\fR. The valid operators, most of which are also available as
commands in the \fBtcl::mathop\fR namespace (see \fBmathop\fR(n)), are listed
below, grouped in decreasing order of precedence:

All internal computations involving integers are done calling on the

in those calculations where values overflowed the range of those types.
Any code that relied on these implicit truncations should instead call

.SS "STRING OPERATIONS"
.PP
String values may be used as operands of the comparison operators,
although the expression evaluator tries to do comparisons as integer
or floating-point when it can,
i.e., when all arguments to the operator allow numeric interpretations,
except in the case of the \fBeq\fR and \fBne\fR operators.
If one of the operands of a comparison is a string and the other
has a numeric value, a canonical string representation of the numeric
operand value is generated to compare with the string operand.
Canonical string representation for integer values is a decimal string
format. Canonical string representation for floating-point values
is that produced by the \fB%g\fR format specifier of Tcl's
\fBformat\fR command. For example, the commands
.PP
.CS
\fBexpr\fR {"0x03" > "2"}
\fBexpr\fR {"0y" > "0x12"}
.CE
.PP
both return 1. The first comparison is done using integer
comparison, and the second is done using string comparison.
Because of Tcl's tendency to treat values as numbers whenever
possible, it is not generally a good idea to use operators like \fB==\fR
when you really want string comparison and the values of the
operands could be arbitrary; it is better in these cases to use
the \fBeq\fR or \fBne\fR operators, or the \fBstring\fR command instead.
.SH "PERFORMANCE CONSIDERATIONS"
.PP
Where an expression contains syntax that Tcl would otherwise perform
substitutions on, enclosing an expression in braces or otherwise quoting it
so that it's a static value allows the Tcl compiler to generate bytecode for
the expression, resulting in better speed and smaller storage requirements.
This also avoids issues that can arise if Tcl is allowed to perform
substitution on the value before \fBexpr\fR is called.
Enclose expressions in braces for the best speed and the smallest
storage requirements.
This allows the Tcl bytecode compiler to generate the best code.
.PP
As mentioned above, expressions are substituted twice:
once by the Tcl parser and once by the \fBexpr\fR command.
For example, the commands
.PP
In the following example, the value of the expression is 11 because the Tcl parser first
substitutes \fB$b\fR and \fBexpr\fR then substitutes \fB$a\fR. Enclosing the
expression in braces would result in a syntax error.
.CS
set a 3
set b {$a + 2}
\fBexpr\fR $b*4
.CE
.PP
When an expression is generated at runtime, like the one above is, the bytcode
compiler must ensure that new code is generated each time the expression
is evaluated. This is the most costly kind of expression from a performance
perspective. In such cases, consider directly using the commands described in
the \fBmathfunc\fR(n) or \fBmathop\fR(n) documentation instead of \fBexpr\fR.
Most expressions are not formed at runtime, but are literal strings or contain
substitutions that don't introduce other substitutions. To allow the bytecode
compiler to work with an expression as a string literal at compilation time,
ensure that it contains no substitutions or that it is enclosed in braces or
otherwise quoted to prevent Tcl from performing substitutions, allowing
\fBexpr\fR to perform them instead.
return 11, not a multiple of 4.
This is because the Tcl parser will first substitute \fB$a + 2\fR for
the variable \fBb\fR,
then the \fBexpr\fR command will evaluate the expression \fB$a + 2*4\fR.
.PP
Most expressions do not require a second round of substitutions.
Either they are enclosed in braces or, if not,
their variable and command substitutions yield numbers or strings
that do not themselves require substitutions.
However, because a few unbraced expressions
need two rounds of substitutions,
the bytecode compiler must emit
additional instructions to handle this situation.
The most expensive code is required for
unbraced expressions that contain command substitutions.
These expressions must be implemented by generating new code
each time the expression is executed.
When the expression is unbraced to allow the substitution of a function or
operator, consider using the commands documented in the \fBmathfunc\fR(n) or
\fBmathop\fR(n) manual pages directly instead.
