Description
Number parsing is slow because of unnecessary conversions from string to array of runes. The code treat them as if those are free, but due to Golang strings being immutable, that is not the case.
Steps to reproduce the issue:
All uses of the library are affected.
Is your feature request related to a problem? Please describe.
When using excelize to read an Excel workbook with dates formatted as DD.MM.YYYY it results in ..YYYY
, e.g. 18.11.2023
is parsed as ..2023
.
Describe the solution you'd like
Once the parser sees the dot .
, it interprets this as a TokenTypeDecimal
and discards the preceding datetime values, e.g. parsing MM.
results in a .
token.
I want to see an MM
token of TokenTypeDatetime
and a .
of type TokenTypeLiteral
being added to the tokens list.
Describe alternatives you've considered
