Merges the code for the Picker and FilePicker into a single Picker that
can show a file preview if a preview callback is provided. This change
was mainly made to facilitate refactoring out a simple skeleton of a
picker that does not do any filtering to be reused in a normal Picker
and a DynamicPicker (see #5714; in particular [mikes-comment] and
[gokuls-comment]).
The crux of the issue is that a picker maintains a list of predefined
options (eg. list of files in the directory) and (re-)filters them every
time the picker prompt changes, while a dynamic picker (eg. interactive
global search, #4687) recalculates the full list of options on every
prompt change. Using a filtering picker to drive a dynamic picker hence
does duplicate work of filtering thousands of matches for no reason. It
could also cause problems like interfering with the regex pattern in the
global search.
I tried to directly extract a PickerBase to be reused in Picker and
FilePicker and DynamicPicker, but the problem is that DynamicPicker is
actually a DynamicFilePicker (i.e. it can preview file contents) which
means we would need PickerBase, Picker, FilePicker, DynamicPicker and
DynamicFilePicker and then another way of sharing the previewing code
between a FilePicker and a DynamicFilePicker. By merging Picker and
FilePicker into Picker, we only need PickerBase, Picker and
DynamicPicker.

Resolves issue #6888 by adding a command to join all selections and yank
them to the specified register. The typed command takes an argument as
the separator to use when joining the selections.
* Fix next/prev tree-sitter inconsistency
Before there where different results going to next or previous due to
sorting not dealing with multiple captures that start/end at the same
pos. I chose to prefer longer matches.
* Revert unnecessary change
* runtime config made clearer
* following Unix FHS
* we probably want to install Helix as a regular user without sudo access
* suggestions adopted from @the-mikedavis
* attempted to synthesise comments given
* capitalisation of second header
* required changes hopefully made
* we should have a match now
* Linux windows dir match
Previously the error message for this potential failure-case was
confusing: "no such file or directory". `hx -g fetch`, `hx -g build` and
the helix-term builder should bail early if the git binary is not
available.
Previously a count or register selection would be lost while opening
the command palette. This change allows using a register selection or
count in any command chosen from the command palette.
Previously the register selection (via `"`) would be lost in the middle
of any key sequence longer than one key. For example, `<space>f` would
clear the register selection after the `<space>` making it inaccessible
for the `file_picker` command.
This behavior does not currently have any effect in the default keymap
but might affect custom keymaps. This change aligns the behavior of the
register with count. Making this change allows propagating the register
to the `command_palette` (see the child commit) or other pickers should
we decide to use registers in those in the future. (Interactive global
search for example.)
