Overview ¶
Package rtfparser implements a parser for the Rich Text Format.
This code is forked from https://github.com/IntelligenceX/fileconversion, which itself is forked from https://github.com/J45k4/rtf-go and extracts text from RTF files.
I ported it from standard lib's regexp package to github.com/dlclark/regexp2, hoping the use of FindNextMatch() instead of FindAllStringSubmatch() might lower memory requirements when processing large files. While this seems to be the case the parser still is very inefficient for larger files (e.g. those containing images.)
