| * TCL_TOKEN_WORD - The token describes one word of a command, | |
| * from the first non-blank character of the word | |
| * (which may be " or {) up to but not including | |
| * the space, semicolon, or bracket that | |
| * terminates the word. NumComponents counts the | |

| * 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. | |

| * initialization that needs to occur before the | |
| * first byte is converted. If the source buffer | |

| * TCL_ENCODING_END - Signifies that the source buffer is the last | |

| * stream. Tells the conversion routine to | |
| * perform any finalization that needs to occur | |
| * after the last byte is converted and then to | |
| * reset to an initial state. If the source | |
| * buffer contains the entire input stream to be | |

| * source character that has no mapping in the | |
| * target encoding. If clear, the converter | |
| * substitues the problematic character(s) with | |
| * one or more "close" characters in the | |
| * destination buffer and then continues to | |
| * convert the source. | |
| * 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 | |
