示例1: GetColumn
/// <summary>
/// Get column of the token
/// * column means text position on a line where all tabs are converted to spaces that first position on a line becomes 0
/// </summary>
private int GetColumn(TokenData tokenData, Func<TokenData, TokenData, TriviaData> triviaDataGetter)
{
// at the beginning of a file.
var previousToken = tokenData.GetPreviousTokenData();
var spaces = 0;
for (; previousToken.Token.RawKind != 0; previousToken = previousToken.GetPreviousTokenData())
{
var triviaInfo = triviaDataGetter(previousToken, tokenData);
if (triviaInfo.SecondTokenIsFirstTokenOnLine)
{
// current token is the first token on line.
// add up spaces so far and triviaInfo.Space which means indentation in this case
return spaces + triviaInfo.Spaces;
}
// add spaces so far
spaces += triviaInfo.Spaces;
// here, we can't just add token's length since there is token that span multiple lines.
