NAME
toke - OpenBIOS tokenizer
SYNOPSIS
toke [options] forth-file
DESCRIPTION
toke is an open-source FCode Tokenizer from the OpenBIOS project.
OPTIONS
-h, -? Print a brief help message and then exit.
-i, --ignore-errors
Generate a Binary Output even if errors were reported.
-l, --load-list
Collect the names of floaded files into an FLoad-List file. The names collected are in the same
form as they were presented in the fload statements.
The name of the FLoad-List File is derived from the name of the binary output file, by replacing
its extension with .fl , or, if the binary output file name had no extension, merely appending the
extension .fl.
The binary output file name used for this purpose is either the one specified on the command line,
or the one created by default.
-o, --output-name OutputFileName,
Direct the binary output (FCode result of Tokenization) to the named file instead of to the
default-named file. This option is not valid when multiple input files are named.
-P, --dependencies
Collect the fully-resolved pathnames of floaded and ENCODEd files into a dependency-list file.
The names collected are in the form that is presented to the host operating system: shell
environment Variables and related expressions will be fully expanded, and the directory within the
include-list in which the file was found will be attached.
The name of the dependency-list file will be the same as that of the FLoad-list file, except that
its extension will be .P instead of .fl.
-v, --verbose
Print additional messages (including advisories) during tokenization.
-I, --Include directory
This tokenizer supports the notion of an include-list. The user creates the include-list by
specifying a number of -I directory pairs on the command-line. All file-reads, whether for an
fload command or an encode-file directive, will involve a search for the named file through the
directories of the include-list, in the order they were supplied on the command-line.
If no include-list is created, file-reads are relative to the current working Directory. If an
include-list is created, file-reads are restricted to the directories within it. For the current
working directory to be included in the file-search, it must be specified explicitly. -I. will
accomplish that quite effectively.
-T, --Trace symbol
This tokenizer supports the notion of a trace-list. The User creates the trace-list by specifying
a number of -T symbol pairs on the command-line.
When a name is defined, whether as an FCode, an alias, a Macro or anything else, either in normal
tokenization mode or "Tokenizer Escape"‐mode, if it matches a symbol that has been added to the
trace list, a trace note message will be issued indicating that a definition of that name has been
created. Subsequent trace note Messages will be issued when the definition of that name is
invoked.
This trace-symbols feature can be helpful during maintenance of legacy code, for instance, when
multiple symbols carry the same name.
-d, --define Symbol[=Value]
Define a command-line symbol and optionally, assign a value to it. If you wish the value to
contain spaces or quotes, you can accomplish that using the shell escape conventions. This
sequence may be repeated. Once a Symbol is defined on the command-line, it stays in effect for the
duration of the entire batch of tokenizations (i.e., if there are multiple input files named on
the command line). Command-line Symbols can be tested for purposes of conditional tokenization, or
their assigned values can be evaluated.
-f, --flag [no]<FlagName>
The tokenizer recognizes a specific set of special-feature flag-names; each is associated with a
specific non-standard variant behavior. Pass the flag-name as an argument to the -f switch to
enable the behavior; to disable it, precede the flag-name with the optional string no.
The settings of the special-feature flags can also be changed or displayed from within the source
input file.
The special-feature flags are all initially set to be enabled, except where noted.
The flag-names and their associated special-features are as follows:
Local-Values
Support IBM-style Local Values ("LV"s). Initially disabled.
LV-Legacy-Separator
Allow Semicolon for Local Values Separator ("Legacy").
LV-Legacy-Message
Display a Warning Message when Semicolon is used as the Local Values Separator.
ABORT-Quote
Allow ABORT" macro.
Sun-ABORT-Quote
ABORT" with implicit IF ... THEN
Abort-Quote-Throw
Use -2 THROW, rather than ABORT, in an Abort" phrase
String-remark-escape
Allow "\ (Quote-Backslash) to interrupt string parsing.
Hex-remark-escape
Allow \ (Backslash) to interrupt hex-sequence parsing within a string.
C-Style-string-escape
Allow the C-style String-Escape pairs \n \t and \xx\ to be treated as special characters in
string parsing.
Always-Headers
Override occurrences of the standard directive headerless in the source with -- effectively
-- headers to make all definitions have a header. Occurrences of the directive external
will continue to behave in the standard manner. Initially disabled.
Always-External
All definitions will be made as though under the external directive; occurrences of either
Standard directive headerless or headers in the source will be overridden. This special-
feature flag will also override the Always-Headers special-feature flag in the event that
both have been specified. Initially disabled.
Warn-if-Duplicate
Display a WARNING message whenever a definition is made whose name duplicates that of an
existing definition. Disabling this flag will suspend the duplicate-names test globally,
until it is re-enabled. A Directive is supported that will suspend the test for the
duration of only a single definition, without affecting global behavior.
Obsolete-FCode-Warning
Display a WARNING message whenever an FCode function is invoked that the Standard
identifies as obsolete.
Trace-Conditionals
Issue advisory messages about the state of conditional tokenization. (Remember that
advisory messages are displayed only if the verbose option -v is set.) Initially disabled.
Upper-Case-Token-Names
Lower-Case-Token-Names When outputting the names of headered functions (token-names) to the
binary output file, override the character-case in which the names appeared in the source,
and convert them to Upper- or Lower- ‐Case, respectively. (These flags do not affect text
string sequences, whose character-case is always preserved.) Initially disabled.
Big-End-PCI-Rev-Level
Save the Revision Level of the Vendor's ROM field of the PCI Header in big-endian byte-
order, rather than little-endian as per the general PCI Standard convention. (This flag
does not affect any other field
of the PCI Header). Initially disabled.
Ret-Stk-Interp
Allow return-stack operations during interpretation. While the standard specifies that
usage of the operators >r, r@, and r> while interpreting is allowed, actual practice in the
industry is inconsistent. Developers who wish to take a more cautious approach to this
question can disable this flag so that any attempt to use the operators >r, r@, and r> in
the interpreting state will generate an ERROR Message.
Also, the pseudo-flag-name help will cause a list of the flag-names and their associated special-features
to be printed.
