Instead, disable the individual entries in the menu.
This is necessary because we are going to add another entry to the menu that is
independent of the selected branch.
We aren't using them, yet, except for deciding whether to show the warning about
hunks with only added lines.
Add a bit of test coverage for parseDiff while we're at it.
When branches are sorted by recency we have this logic that first loads the
branches so that they can be rendered quickly; in parallel, it starts loading
the reflog in the background, and when that's done, it loads the branches again
so that they get their recency values. This means that branches are loaded twice
at startup.
We don't need this logic when branches are not sorted by recency, so we can
simply load branches and reflog in parallel like everything else.
This shouldn't change any user observable behavior, it just avoids doing
unnecessary work at startup.
For tooltips that are just one or two characters longer than the available
width, the last word would be cut off. On my screen this happened for the
tooltip for the fixup command.
For custom commands it is useful to select an earlier command and have it copied
to the prompt for further editing. This can be done by hitting 'e' now.
For other types of suggestion panels we don't enable this behavior, as you can't
create arbitrary new items there that don't already exist as a suggestion.
In the custom commands panel you can now tab to the suggestions and hit 'd' to
delete items from there. Useful if you mistyped a command and don't want it to
appear in your history any more.
This lets us get rid of a few more calls to Error(), and it simplifies things
for clients of OnWorker: they can simply return an error from their callback
like we do everywhere else.
When exiting filtering mode, we currently keep the selection index the same in
the commits panel. This doesn't make sense at all, since the index in the
filtered view has no relation to the index in the unfiltered view.
I often use filtering mode (either by path or by author) to find a given commit
faster than I would otherwise be able to. When exiting filtering mode, it's
useful to keep the same commit selected, so that I can look at the surrounding
commits, see which branch it was a part of, etc. So reselect the commit again
after exiting filtering mode.
Sometimes this is not possible, most likely when the commit is so long ago that
it's outside of the initial 300 range. In that case, at least select the commit
again that was selected before I entered filtering; this is still better than
arbitrarily keeping the same selection index.
We pass all of them to a single editor command, hoping that the editor will be
able to handle multiple files (VS Code and vim do).
We ignore directories that happen to be in the selection range; this makes it
easier to edit multiple files in different folders in tree view. We show an
error if only directories are selected, though.
Some operations don't support switching to the editor from the commit message
panel; an example is the commit message panel that appears when moving a custom
patch into a new commit. Disable the "open in editor" menu entry in this case,
instead of silently doing nothing.
By default we now search for substrings; you can search for multiple substrings
by separating them with spaces. Add a config option gui.filterMode that can be
set to 'fuzzy' to switch back to the previous behavior.
... and when recalling a commit message from an old commit by pressing up-arrow.
This is necessary because committing turns our soft line breaks into real ones,
but when rewording we want to turn them back into soft ones again, so that it's
possible to insert words at the beginning of a paragraph and have everything
rewrap nicely.
This is only a best effort; the algorithm only removes those hard line breaks
that can be removed without changing the way the message looks. This works well
when the previous commit message was wrapped at the same width, which for most
users should be the most common case; but if it wasn't, the result is not great.
Specifically, if the old wrap width was smaller, some hard line breaks just
won't be removed; if it was wider though, you'll get an unpleasant comb effect
with alternating long and short lines. In such a case it's best to switch to the
editor and use whatever wrapping features you have there (e.g. alt-Q).
