|
||
* (which may be " or {) up to but not including
|
||
* the space, semicolon, or bracket that

* word. This includes, for example, sub-tokens

* of TCL_TOKEN_VARIABLE tokens.
|
||
* TCL_TOKEN_SIMPLE_WORD - This token is just like TCL_TOKEN_WORD except
|
||
* that the word is guaranteed to consist of a
|
||
* single TCL_TOKEN_TEXT sub-token.
|
||
* TCL_TOKEN_TEXT - The token describes a range of literal text
|
||
* that is part of a word. NumComponents is
|
||
* always 0.
|
||
* TCL_TOKEN_BS - The token describes a backslash sequence that
|
||
* must be collapsed. NumComponents is always 0.
|
||
* TCL_TOKEN_COMMAND - The token describes a command whose result
|
||
* must be substituted into the word. The token
|
||
* includes the enclosing brackets. NumComponents
|
||
* is always 0.
|
||
* TCL_TOKEN_VARIABLE - The token describes a variable substitution,
|
||
* including the dollar sign, variable name, and
|
||
* array index (if there is one) up through the
|
||
* right parentheses. NumComponents tells how
|
||
* many additional tokens follow to represent the
|
||
* variable name. The first token will be a
|
||
* TCL_TOKEN_TEXT token that describes the
|
||
* variable name. If the variable is an array
|
||
* reference then there will be one or more
|
||
* additional tokens, of type TCL_TOKEN_TEXT,
|
||
* TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
|
||
* TCL_TOKEN_VARIABLE, that describe the array

||
* index; numComponents counts the total number
|
||
* of nested tokens that make up the variable
|
||
* reference, including sub-tokens of
|
||
* TCL_TOKEN_VARIABLE tokens.
|
||
* TCL_TOKEN_SUB_EXPR - The token describes one subexpression of an
|
||
* expression, from the first non-blank character
|
||
* of the subexpression up to but not including
|
||
* the space, brace, or bracket that terminates
|
||
* the subexpression. NumComponents counts the
|
||
* total number of following subtokens that make
|
||
* up the subexpression; this includes all
|
||
* subtokens for any nested TCL_TOKEN_SUB_EXPR
|
||
* tokens. For example, a numeric value used as a
|
||
* primitive operand is described by a
|
||
* TCL_TOKEN_SUB_EXPR token followed by a
|
||
* TCL_TOKEN_TEXT token. A binary subexpression
|
||
* is described by a TCL_TOKEN_SUB_EXPR token
|
||
* followed by the TCL_TOKEN_OPERATOR token for
|
||
* the operator, then TCL_TOKEN_SUB_EXPR tokens
|
||
* for the left then the right operands.
|
||
* TCL_TOKEN_OPERATOR - The token describes one expression operator.
|
||
* An operator might be the name of a math
|
||
* function such as "abs". A TCL_TOKEN_OPERATOR
|
||
* token is always preceded by one
|
||
* TCL_TOKEN_SUB_EXPR token for the operator's
|
||
* subexpression, and is followed by zero or more
|
||
* TCL_TOKEN_SUB_EXPR tokens for the operator's
|
||
* operands. NumComponents is always 0.
|
||
* TCL_TOKEN_EXPAND_WORD - This token is just like TCL_TOKEN_WORD except
|
||
* that it marks a word that began with the
|
||
* literal character prefix "{*}". This word is
|
||
* marked to be expanded - that is, broken into
|
||
* words after substitution is complete.

* contains the entire input stream to be

* converted, this flag should be set.
|

* TCL_ENCODING_END - Signifies that the source buffer is the last

* converted, this flag should be set.
|
||
* TCL_ENCODING_STOPONERROR - Not used any more.
|
||
* TCL_ENCODING_NO_TERMINATE - If set, Tcl_ExternalToUtf does not append a
|
||
* terminating NUL byte. Since it does not need
|
||
* an extra byte for a terminating NUL, it fills
|
||
* all dstLen bytes with encoded UTF-8 content if
|
||
* needed. If clear, a byte is reserved in the
|
||
* dst space for NUL termination, and a
|
||
* terminating NUL is appended.
|
||
* TCL_ENCODING_CHAR_LIMIT - If set and dstCharsPtr is not NULL, then

* Tcl_ExternalToUtf takes the initial value of
|
||
* *dstCharsPtr as a limit of the maximum number
|
||
* of chars to produce in the encoded UTF-8
|
||
* content. Otherwise, the number of chars
|
||
* produced is controlled only by other limiting
|
||
* factors.

||
* these are bit masks.

*
|

* NOTE: THESE BIT DEFINITIONS SHOULD NOT OVERLAP WITH INTERNAL USE BITS
|
