Changelog
- (Breaking) There has been some changes in the server protocol.
Make sure to kill the old server process when you update to avoid errors (i.e. lf -remote 'quit!').
- (Breaking) A new server command query is added to expose internal state to users (#1384) (by @joelim-work).
A new builtin command cmds is added to display the commands. The old builtin command jumps is now removed.
The builtin commands maps and cmaps now use the new server command.
- (Breaking) Environment variable exporting for files and options are not performed anymore while previewing and cleaning to avoid various issues with race conditions (#1354) (by @joelim-work).
Cleaning program should now instead receive an additional sixth argument for the next file path to be previewed to allow comparisons with the previous file path.
User options (i.e. user_{option}) are now exported whenever they are changed (#1418) (by @raslop).
- (Breaking) Command outputs are now exclusively attached to stderr to allow printing the last directory or selection to stdout (#1399 and #1402) (by @joelim-work).
Two new command line options -print-last-dir and -print-selection are added to print the last directory and selection to stdout.
The example script etc/lfcd.sh is updated to use -print-last-dir instead.
Other lfcd scripts are also likely to be updated in the future to use the new method (patches are welcome).
- (Breaking) The option ruler is now deprecated in favor of its replacement rulerfmt (#1386) (by @joelim-work).
The new rulerfmt option is more capable (i.e. displays option values, supports colors and attributes, and supports optional fields) and more consistent with the rest of our options.
See the documentation for more information.
