Noteworthy Changes in rfcfold Releases

Version 1.3.0 (2021-01-30)

  • Support file names starting with a hyphen ('-').

  • Add forced folding to both folding strategies.

  • Support using a non-regular file, e.g., a pipe, as input file. This allows the use of rfcfold as any part of a pipeline by using /dev/stdin as input filename and /dev/stdout as output filename. Both /dev/stdin and /dev/stdout are provided by Bash if the operating system does not provide them itself.

  • Use a POSIX compatible method to detect ASCII control or non-ASCII characters in an input file for folding.

  • Prefer GNU grep installed as ggrep over the grep included in the operating system, if available. On some systems, e.g. macOS, this may increase the maximum folding column value for rfcfold, if combined with using GNU sed (e.g, as gsed).

Version 1.2.1 (2020-12-15)

  • Update NEWS.md file with current information.

Version 1.2.0 (2020-12-15)

  • More reliable reporting of folding errors.

  • Adjust sed usage to conform to POSIX specification. Before, only GNU Sed was known to work. Now the sed implementation included in macOS is known to work, too.

  • Add a NEWS.md file to list noteworthy changes in released versions.

Version 1.1.0 (2020-07-06)

  • Removal of arbitrary upper limit for folding column. The practical upper limit is determined by the available grep and sed implementations.

Version 1.0.1 (2020-06-27)

  • Improve portability by replacing problematic use of echo with printf. This makes rfcfold compatible with the Z shell (zsh).
