If a previous command in the history contained a literal control character (eg via Ctrl-v, Ctrl-[), when the command was printed, the control character was printed and whatever control sequence it was part of was interpreted by the terminal. For instance, if a command contained the SGR sequence `^[[31m`, all subsequent output from `atuin history list` would be in red. Slightly less of a problem, control characters would also not appear in the interactive search widget although they would be printed when selected. This meant `echo '^[[31foo'` would appear as `echo '[31foo'`. When the entry was selected, the same problem as before would occur and, for the example above, `echo 'foo'` would be printed with 'foo' in red. When copied, this command would not behave the same as the original as it would be missing the control sequence. This adds an extension trait to add a method to anything that behaves like a string to escape ascii control characters and return a string that can be printed safely. This string can then be copied and run directly without having to add the control characters back. |
