Emacs 26 added built-in support for line numbers, relative line numbers, and
visual line numbers. Spacemacs supports only absolute and relative, but there is
no way to access the visual mode. It's hard to get around this, since Spacemacs
abstracts line numbers to a reasonably high degree.
Arguably, `visual` is much more useful than `relative` as a display type. Visual
line numbers are like relative line numbers, but only lines that are actually
showing are counted. This means:
1. Hidden lines are not counted. If a large amount of text is folded, the line
numbers won't jump from "10" to "546". This is particularly useful in
buffers like `magit-status`, where a large amount of information is folded
by default.
2. Lines that are wrapped are counted as multiple lines, since they're being
displayed as multiple lines in the editor. Each visual line will be
numbered - unlike `relative`, where the entire thing is numbered... Once.
With standard relative line numbers, you can't actually navigate using the line
numbers in the sidebar as soon as folded or wrapped lines are introduced. Since
this is one of the main use cases for relative line numbers, this is a big
problem.
Visual mode fixes that problem. Every line that's being displayed is labelled.
Numbers always correspond to the actual number of lines you'd need to navigate
to reach that line.
This commit extends Spacemacs' line number interface to provide visual line
number support.
Fixed the minibuffer showing: `nil`
when `select-enable-clipboard` is `nil` and the current files
path/dir/file/line/column/etc. is copied with the keys under
the prefix: `SPC f y`
New var: dotspacemacs-new-empty-buffer-major-mode
Set to a symbol naming a mode (e.g. 'text-mode) to apply that major mode to any
buffers newly created in Spacemacs by spacemacs/new-empty-buffer.
Fixes#12382.
It is nicer when user can stay in the "home row" for basic operations like
zooming in and out
Font Scaling Transient State
`k` scale up
`j` scale down
Frame Transparency Transient State
`k` increase transparency
`j` decrease transparency
Zoom Frame Transient State
`k` zoom frame in
`j` zoom frame out
Added two additional Zoom Frame TS keys:
`m` max frame
`f` fullscreen
Window sizing and layouts can be affected by a large transient state hint,
so having a option for minified hint is especially useful here.
Also reformats the full hint to place `golden ratio` under the "Resize" heading,
reducing overall height by one row.
Moved:
- ("ai" "irc") to both the `erc` and `rcirc` layers. They don't have to be
renamed until the layers are loaded.
- ("ay" "ipython notebook") to the `ipython-notebook` layer.
- ("p$" "projects/shell")
("'" "open shell")
("as" "shells")
to the `shell` layer.
- The commands with keybindings from spacemacs-bootstrap/packages.el to
spacemacs-defaults/keybindings.el.
Removed:
- ("gd" "diff") it seems to be an old group name, there's no `SPC g d` group at
the moment.
- ("Re" "elisp") and ("Rp" "pcre") because they have moved to:
("xr" "regular expressions")
("xre" "elisp")
("xrp" "pcre")
- ("xm" "move") seems to be an old move text group, the current keybindings are
`SPC x J` and `SPC x K` which opens the Move Text Transient State.
- ("b" "persp-buffers") because `SPC b` is also renamed as ("b" "buffers") which
is more general and not persp-mode specific.
problems:
the delete file prompt doesn't show which file it's about to delete,
and when the deletion request is canceled, then the question remains in the
minibuffer (the text disappears when an action updates the minibuffer, like
moving the cursor, but it might be confusing to still be seeing the question
after it's been answered)
solution:
show the file name in the delete file prompt, and show a canceled message
By analogy with the "zz", "zb", "zt" vim / evil bindings, this adds an
additional key binding "z" for `recenter-top-bottom` to the following
transient states which navigate around the buffer in large jumps:
- auto-symbol-highlight
- error
- buffer
- vcs
- org-babel
This allows for repositioning of the buffer for visibility without having to
exit the transient state.
Minor updates are also made to documentation of other transient states.
1. Fix `short-name` for directories. Previously it was empty string.
2. Remove redundant check for existing buffer:
1. `(get-buffer new-name)` always return `nil`, because `new-name` is a path
to file, not a file name.
2. `(find-file new-name)` handles this situation.
3. `dired-rename-file` handles this situation as well.
3. Use `dired-rename-file` to do the dirty stuff.
1. Renames files and directories.
2. All associated buffers are updated. If you rename a directory, all buffers
that were visiting files from that directory now visit files from new
directory.
4. Properly handle recentf list update for directories - all files from the
renamed directory are removed from recentf list and the same files but from
new directory are added back.
problem:
`'face 'minibuffer-prompt` and `new-name` are shown with an orange color,
and `describe-char` shows that they have the face: `font-lock-warning-face`
solution:
adding a newline before them removes the orange warning color
Before this commit, Spacemacs assigned an anonymous function to the
compilation-finish-function variable. This variable was deprecated
in Emacs 22.1 and removed in Emacs 27.1 in favor of the
compilation-finish-functions hook. Consequently, the assignment has
no practical effect in Emacs 27.1.
Although we could add the Spacemacs function to the new
compilation-finish-functions hook, the function serves little purpose; it
prints a generic message when compilation succeeds:
compilation ok.
and it prints the key binding for spacemacs/next-error when compilation
fails:
There were errors. Use SPC e n to visit.
However Emacs already prints messages to indicate success or failure,
respectively:
Compilation finished
or (for example)
Compilation exited abnormally with code 1
Because the Spacemacs function prints its "There were errors" message
immediately after Emacs prints its "Compilation exited abnormally" message,
the latter was obscured. Because the exit code in Emacs's message could be
useful and the added value of the Spacemacs function's message is minimal,
we can simply delete the Spacemacs function.
* layers/+spacemacs/spacemacs-defaults/funcs.el
(compilation-finish-function): Delete the assignment and anonymous
function.
The `SPC f a` keybinding was already used by the `fasd` layer so a
workaround had to be found for the newly introduced one.

Thanks @agzam for pointing it out and investigating potential solutions.
Define an alias and use it internally so that (1) the name of the command will
be better to understand what it does than the original name and (2) Helm or Ivy
interface is invoked instead of Ido.
These are suggested in PR #11115.
Add aliases for commands that ido-mode remaps that we want to bind to
Spacemacs keys, and use these aliases in the Spacemacs key bindings so that
these bindings invoke the original commands rather than the ido commands.
