It also requires the +|+autocmd| feature. + +IMPLEMENTATION *redact_pass-implementation* + +The options are disabled globally rather than attempting to set them local to +the buffer only, which was the flawed approach of previous versions. This is +mostly because of the 'viminfo' option; it's global, and there's no meaningful +way to exclude information from the sensitive buffer from appearing in it. + +Because the typical use case for editing a password file in Vim is that you +load and change a single short document, and then quit, it's more sensible to +just turn the relevant options off completely, and makes what the plugin is +doing more reliable and straightforward to understand. + +AUTHOR *redact_pass-author* + +Written and maintained by Tom Ryder <tom@sanctum.geek.nz>. + +LICENSE *redact_pass-license* + +Licensed for distribution under the same terms as the pass(1) project. + + vim:tw=78:ts=8:ft=help:norl: |
