Originally I thought we'd benefit from this change in this branch; turns
out that we didn't after all, because we changed the approach, but it's
a nice cleanup anyway, so we include it here.
Convert the remaining *Alt/*Alt[12] sibling fields (PrevItem/NextItem,
GotoTop/GotoBottom, PrevBlock/NextBlock, ScrollUpMain/ScrollDownMain,
OptionMenu, ConfirmInEditor, DiffingMenu) so the merge mechanism folds
their values into the corresponding main multi-key binding at config
load. The redundant alt-only Binding registrations across the various
controllers and the global keybindings file are gone: the merged main
field already carries every key, so the for-loop in SetKeybinding
registers them all.
This is a pure refactor in preparation for letting users configure multiple
alternate bindings for a single command. Every Binding still has exactly one
key, so nothing changes visibly: the cheatsheet, the on-screen options bar,
and the keybindings menu all render identically.
When a Binding ends up with multiple keys, the on-screen options bar will
show only the first (to avoid clutter); the cheatsheet will show all of them (in
a later commit). For now both paths take Key[0].
MenuItem.Key is changed in the same way, it also has a slice of keys now.
In this commit we keep the name `Key` in Binding, KeybindingOpts and MenuItem,
instead of renaming them to `Keys` right away, in order to keep the diff a bit
more readable. We'll do the rename separately in the next commit.
Modifiers were moved into Key in 22169e22f, but the separate Modifier field
on types.Binding and gocui.keybinding was left behind. The keypress matcher
already compares modifiers via Key.Equals, so the old field is never read on
the dispatch path; it just got passed through SetKeybinding and stored.
Drop it from gocui.keybinding, types.Binding, and the SetKeybinding /
DeleteKeybinding signatures, and remove every now-redundant Modifier:
gocui.ModNone struct field. Mouse bindings keep their own Modifier (on
ViewMouseBinding) since that path still consults it.
This bundles the keyName and a rune, so that we don't have to pass these around
separately everywhere. This should make it easier to swap out the rune for a
string when we upgrade to tcell v3.
I copied all files except dot files (.github and .gitignore), the _examples
folder, and go.mod/go.sum.
At some point we may want to copy the files back to the gocui repo when other
clients (e.g. lazydocker) want to use the newer versions of them.
This fixes two problems:
- if the previously focused view (behind the panel) was a list view, it would
look like the click would select a different row, because gocui would still
set the view's cursor position, which is used to draw the highlighted row
- it was still possible to click on tab headers, and this would dismiss the
panel
So far, confirmations and prompts were handled by the same view, context, and
controller, with a bunch of conditional code based on whether the view is
editable. This was more or less ok so far, since it does save a little bit of
code duplication; however, now we need separate views, because we don't have
dynamic keybindings, but we want to map "confirm" to different keys in
confirmations (the "universal.confirm" user config) and prompts (hard-coded to
enter, because it doesn't make sense to customize it there).
It also allows us to get rid of the conditional code, which is a nice benefit;
and the code duplication is actually not *that* bad.
This doesn't change behavior, just makes the code a little bit easier to
understand: the outermost condition is "do we show a popup and is the mouse
event for some other view than the focused one". Only if that's true do we need
to define the isCommitMessageView function, and check whether both views belong
to the commit message editor.
If a DisabledReason has its AllowFurtherDispatching flag set, it is returned as
a ErrKeybindingNotHandled error, instead of shown as a toast right away. This
allows gocui to continue to dispatch the keybinding, and we can unwrap the error
at the other end (in our global ErrorHandler) and display it then.
This allows having keybindings for the same key at the local and global levels,
and they will continue to be dispatched even if the first one returns a
DisabledReason. It is opt-in, so we only use it for cases where we know that a
local and a global handler share the same (default) keybinding.
There was no reason to declare a variable for disabledReason, assign it inside
the "if binding.GetDisabledReason != nil" statement, and then check its value
again after that if statement. Move all that code inside the first if statement
to make the control flow easier to understand.
This makes it possible to "silently" disable a keybinding. The effect is the
same as putting the check in the handler and returning nil from there, except
that doing it this way also hides it from the bottom line if DisplayOnScreen is
true.
This might seem controversial; in many cases the client code gets longer,
because it needs an extra line for an explicit `return nil`. I still prefer
this, because it makes it clearer which calls can return errors.
This solves several problems that arise from opening a menu while the prompt is
open. We might try to solve these in a different way, e.g. by dismissing the
search prompt before opening a menu, but restricting what you can do while the
prompt is open seems like the more robust fix.
To achieve this, we
- call resetKeyBindings both when opening and when closing the search/filter
prompt
- change the keybindings to only contain the ones for the search prompt when
that context is active.
I often copy hashes in the commits panel in order to paste them into Github
comments (or other places), and I can't stand it when they have the full length.
I picked a default of 12 for this; I find this to be a good middle ground
between being reliable in large repos (12 still works in the linux kernel repo
today, but it might not be enough in really huge repos) and not being too ugly
(many smaller repos can probably get away with less).
We deliberately don't change this for the "Copy to clipboard" menu, since this
gives users a way to copy the unabbreviated sha if they need this occasionally.
This adds a bunch of tooltips to keybindings and updates some keybinding descriptions (i.e. labels).
It's in preparation for displaying more keybindings on-screen (in the bottom right of the screen),
and so due in part to laziness it shortens some descriptions so that we don't need to manage both
a short and long description (for on-screen vs in-menu). Nonetheless I've added a ShortDescription
field for when we do want to have both a short and long description.
You'll notice that some keybindings I deemed unworthy of the options view have longer descriptions,
because I could get away with it.
We want to show an error when the user tries to invoke an action that expects only
a single item to be selected.
We're using the GetDisabledReason field to enforce this (as well as DisabledReason
on menu items).
I've created a ListControllerTrait to store some shared convenience functions for this.
We have not been good at consistent casing so far. Now we use 'Sentence case' everywhere. EVERYWHERE.
Also Removing 'Lc' prefix from i18n field names: the 'Lc' stood for lowercase but now that everything
is in 'Sentence case' there's no need for the distinction.
I've got a couple lower case things I've kept: namely, things that show up in parentheses.
