| G3D::TextInput::Settings::Settings | ( | ) |
Here is the call graph for this function:| bool G3D::TextInput::Settings::caseSensitive |
When parsing booleans and msvcFloatSpecials, is case significant? Default is {true}
| bool G3D::TextInput::Settings::cppBlockComments |
If true, C-style slash-star marks a multi-line comment.
See generateCommentTokens for rules on how this is applied.
Default is true.
| bool G3D::TextInput::Settings::cppLineComments |
If true, // begins a single line comment.
See generateCommentTokens for rules on how this is applied.
Default is true.
| bool G3D::TextInput::Settings::escapeSequencesInStrings |
If true, \r, \n, \t, \0, \\ and other escape sequences inside strings are converted to the equivalent C++ escaped character. If false, backslashes are treated literally. It is convenient to set to false if reading Windows paths, for example, like c:\foo\bar.
Default is true.
| Set<std::string> G3D::TextInput::Settings::falseSymbols |
See trueSymbols. Default is {false}
| bool G3D::TextInput::Settings::generateCommentTokens |
If true, comments enabled by cppBlockComments, cppLineComments and otherLineComments will generate their respective tokens. If false, the same settings will enable parsing and ignoring comments
Default is false.
| bool G3D::TextInput::Settings::generateNewlineTokens |
If true, newlines will generate tokens. If false, newlines will be discarded as whitespace when parsed outside of other tokens.
Default is false.
| bool G3D::TextInput::Settings::msvcFloatSpecials |
Parse "-1.#IND00" as the floating point number returned by G3D::nan(), "-1.#INF00" as - G3D::inf(), and "1.#INF00" as G3D::inf().
Note that the C99 standard specifies that a variety of formats like "nan" are to be used; these are supported by G3D::TextInput::Settings::simpleFloatSpecials.
An alternative to specifying msvcFloatSpecials is to read numbers as:
Token x = t.read();
Token y = t.peek();
if ((x.string() == "-1.") &&
(y.string() == "#INF00") &&
(y.character() == x.character() + 3) &&
(y.line() == x.line()) {
t.read();
return nan();
}
// ... similar cases for inf
If the single-comment character was #, the floating point special format overrides the comment and will be parsed instead.
If signedNumbers is false msvcFloatSpecials will not be parsed.
Default is true.
| char G3D::TextInput::Settings::otherCommentCharacter |
If not '\0', specifies a character that begins single line comments ('#' and '' are popular choices). This is independent of the cppLineComments flag. If the character appears in text with a backslash in front of it, it is considered escaped and is not treated as a comment character.
Default is '\0'.
| char G3D::TextInput::Settings::otherCommentCharacter2 |
Another (optional) 1-comment character. Useful for files that support multiple comment syntaxes. Default is '\0'.
| bool G3D::TextInput::Settings::otherLineComments |
If true, otherCommentCharacter and otherCommentCharacter2 are used to begin single line comments in the same way cppLineComments is.
See generateCommentTokens for rules on how this is applied.
Default is true.
| bool G3D::TextInput::Settings::proofSymbols |
Parse the following set of useful proof symbols:
=> ::> <:: :> <: |- ::= := <-
Default is false.
| bool G3D::TextInput::Settings::signedNumbers |
If true, "-1" parses as the number -1 instead of the symbol "-" followed by the number 1. Default is true.
| bool G3D::TextInput::Settings::simpleFloatSpecials |
Parses "+inf', "-inf", "inf", "nan" as floats instead of symbols. Defaults to true.
| char G3D::TextInput::Settings::singleQuoteCharacter |
The character to use as a single quote. Defaults to "'" (backquote), occasionally useful to set to "`" (forward quote) or to "," (comma) for reading CSV files.
| bool G3D::TextInput::Settings::singleQuotedStrings |
If true, strings can be marked with single quotes (e.g., 'aaa'). If false, the quote character is parsed as a symbol. Default is true. Backquote (`) is always parsed as a symbol.
| std::string G3D::TextInput::Settings::sourceFileName |
If set to a non-empty string, that string will be used in place of the real file name (or in place of a pseudonym constructed from the buffer if given FROM_STRING) in tokens and exceptions.
Default is empty.
| int G3D::TextInput::Settings::startingLineNumberOffset |
Added to the line number reported by peekLineNumber and in exceptions. Useful for concatenating files that are parsed separately. Default is zero.
| Set<std::string> G3D::TextInput::Settings::trueSymbols |
All symbols that will become the 'true' boolean token. See also caseSensitive. Clear this value to disable parsing of true booleans.
Default is {true}.
