A very practical way to remove methods from generic functions.
SLY no longer bypasses completing-read-function to provide basic
ido completion. This used to make sense when fewer fancy
well-behaved completion packages existed. That's no longer the case
so we shouldn't override the user's preference.
If you haven't yet, just M-x package-install RET company-mode, to
enable company. It should start working in every SLY buffer.
Moreover, a new "lazy" way to SLY collect completions from the Lisp backend means that user input is not blocked if this takes a long time. The result is a much more responsive on-the-fly completion experience.
If you don't like company, you can still use the normal on-request TAB completion, which also features an improved UI.
Helm users should now get access to the full capabilities of SLY's
completion function without needing to install any extra packages.
Just need to M-x sly-symbol-completion-mode to turn off SLY's
default completion UI. (#303)
A redesigned completion backend replaces the legacy contribs
sly-fuzzy and sly-c-p-c. The new "flex" backend considers package
designators in the search string so you can complete other package's
symbols even when outside a package.
Here's an example:
CL-USER> (quiloa) -> (ql:quickload)
CL-USER> (scan) -> (ppcre:scan)
CL-USER> (setf locadirs) -> (setf ql:*local-project-directories*)
CL-USER> (mvbind) -> (multiple-value-bind)
Flex completion is on by default, but that can be changed via
sly-complete-symbol-function. The
documentation has more
information.
Package-local nicknames are also considered (provided your implementation supports them).
Manual has been reviewed from top to bottom. It should be much easier to navigate and nicer read in general, thouch it still needs quite some proofreading
A new chapter for existing SLIME users figures prominently in the top-level.
Presently no major omissions (except maybe for multiple inspectors). Reorganized nodes into a new structure not so focused on core vs contribs. Deleted stale sections. REPL section heavily rewritten to explain output types and backreferences.
This is a counterpart to the existing M-x sly-export-symbol-at-point, bound to C-c e. It strips the symbol under point of its package designator, and adds it under the :import-from subclause of the current package's defpackage form. An improvement suggested and implemented by Alexander Artemenko (github #147).
The UI for SLY Stickers, particularly for M-x sly-stickers-replay
has been cleanup up. Upon entering the replay mode, SLY may ask user
if she wants to delete the previous recordings, a commonly forgotten
but useful pre-step (an idea by Javier Olaechea, github #91). Also,
window management is less random.
Inspector, debugger, and other buffers pertaining to a connection are
automatically killed when the connection is closed. The types of
buffers that are exempt from this is configurable in a new
sly-keep-buffers-on-connection-close defcustom, which lists
REPL buffers by default.
In minibuffer prompts like the one of M-x sly-inspect, autodoc
information is available and displayed temporarily in the mode-line.
These clear recent output and the whole REPL, respectively.
The "Copy call to REPL" funcionality in the Trace Dialog and SLY-DB buffers now understands that symbols and numbers can be printed directly in the reconstructed function call, which eases reading.
A problem encountered by Zach Beane.
When finding the definition of a generic function with M-., an xref buffer pops up in a (possibly reused) window, showing code locations. When selecting one of those locations, make sure to honor the original intent of M-. of switching buffers in the original window. Quit the xref window should fully restore the previous window configuration. Thanks to Michael Fiano for insisting on what is indubitably the correct behavior (github #123).
Calling sly-mrepl interactively, either via M-x or
sly-selector-map switches to buffer in the current
window. Accessing the REPL indirectly (by returning objects into it
form other modes) attempts to pop the buffer in another window.
A problem encoutered by Zach Beane.
The Travis CI infrastructure now uses roswell and emacs-travis
instead of cl-travis and apt, respectively. Thus no longer needs
Travis's sudo and uses directory caching, resulting in much faster
builds.
Customize the formats that integer numbers get presented back to SLY, additionally to the binary, octal and hex defaults. Good when working with Unix Epoch times, for example. See manual "Other configurables" for documentation and example.
This makes a prefixless M-x sly switch to an active connection
instead of starting a new one. Customize this to never to never
prompted, or to always to always move to the first live connection.
If the Slynk-side of a contrib fails to load for whatever reason, a CONTINUE restart is provided. On the SLY side, the user can choose to disable that contrib temporarily.
Courtesy of Zach Shaftel [email protected], sly-cl-indent.el no longer clobbers or conflicts with Emacs's own cl-indent.el. The cl.el library is no longer required, not even at compile-time or in tests. A lot of cleanup and performance improvements.

M-- sly-apropos prompts for just the package. A suggestion of Javier
Olaechea (github #53).
C-u sly-apropos allows searching all packages (github #53)
Discovery of the "sexp near point" has been much improved and won't error cryptically when there is no macroexpansion possible.
paredit-mode works in the REPL, as does Emacs 24.4's
electric-pair-mode or other parenthesis-matching tools, just like in
any other Lisp buffer.
New variable sly-mrepl-output-filter-functions for REPL
output. These work like comint-preoutput-filter-functions. Functions
like ansi-color-apply are good candidates (github #38).
When using multiple REPL, frame variables from SLY-DB triggered in secondary REPLs, when returned with M-RET, appear in the correct REPL.
mREPL notes are synched displayed correctly at the "process mark", not
"output mark". This avoids some ; note in wrong
places (github #45).
Popping up SLY-DB buffers from different threads no longer
misteriously updates a REPL's environment for *, **, ***, etc...
Tearing down a reverse-isearch with C-g no longer errors (github

sly-stickers is a live code annotation tool, a replacement for the
"print" statements that are often included for debugging the value of
a particular variable or expression. See a much more complete
description in http://joaotavora.github.io/sly/#SLY-Stickers.
Thanks to Artem Malyshev for early testing and ideas.
The documentation rewrite is underway (github issue #9), mentioning only a residual amount of SLIME-specific functionality. Browse to http://joaotavora.github.io/sly for the online version in HTML.
The README.md file has an updated install recipe, basically M-x package-install RET sly RET. Thanks to Kan-Ru Chen for the idea.
The "comma" shortcut for "sayoonara", "restart lisp", "in-package" commands has been restored and uses ido-style completion by default. Suggested by Javier Olaechea (github #18).
C-c C-z switches to the nearest REPL, much like sly-mrepl-sync,
but without changing the REPL's state. Suggested by Javier Olaechea
(github #13).
sly-mrepl-sync is now bound to C-c ~ in any SLY buffer. A C-u
prefix will also yank the last expression into the current REPL.
New customization variable sly-mrepl-prevent-duplicate-history
offers finer control over saved history.
When a connection disconnects, a status line is inserted in the REPL stating the reason for disconnection (network failure, user abort, etc...)
SLY asks the user to confirm the Lisp to kill with M-x sly-quit or
disconnect with M-x sly-disconnect. It also doesn't ask any
irrelevant questions about switching to a default connection when it
doesn't exist (github #5).

Slynk is SLY's implementation of Swank, the supporting Lisp server where Emacs connects to. A project-wide rename was performed, including this NEWS.md file.
A sly-retro contrib, enabled by default ensures that:
- SLY can still talk to non-lisp Swank backends
- SLY can serve requests for the Swank protocol
- Most user customization in
~/.swankrcis still valid in SLY.
For details on the architecture of these changes, see the "Swank is now called Slynk" in the CONTRIBUTING.md.
Thanks to Zach Beane for the great name.
Where applicable, SLY tracks bugfixes and improvements contributed to SLIME:
sly-autodochas been rewritten by Helmut Eller. Multiline is enabled by default.- Experimental support for MKCL has been added
Since this is the first pre-release of SLY since the fork, this entry focuses directly on the differences to SLIME.
The sly-mrepl contrib is a extensively redesigned
Read-Eval-Print-Loop (REPL) for SLY.
Multiple independent REPLs can be created with the sly-mrepl-new
command.
sly-mrepl is fully based on Emacs's comint.el and as such has a
more familiar interface for history navigation. C-r and C-M-r,
when used at the prompt, should provide a bash/zsh-like experience.
The prompt gives a visual indication of long-running evaluations that haven't returned yet.
The prompt gives a visual indication of the number of debugger levels currently caused by the last evaluation.
Every return part can be inspected and re-returned as the last value.
C-c ~ on any Lisp file switches to the REPL and synchronized its
*PACKAGE* and *DEFAULT-PATHNAME-DEFAULTS* with the file's.
Output redirection is automatically setup. The first REPL created is
the target for all threads' output onto the standard output
streams. REPLs created afterward only see their own output. To turn
this off configure the Slynk-side variable
SLYNK-MREPL:*GLOBALLY-REDIRECT-IO*.
A dedicated stream connection for output is automatically set
up. Configure the SLYNK-MREPL:*USE-DEDICATED-OUTPUT-STREAM* if it
doesn't suit you.
There is saner scrolling behavior as provided by the comint.el
substrate. The variables comint-scroll-show-maximum-output,
comint-scroll-to-bottom-on-input and
comint-scroll-to-bottom-on-output (which see) are set to nil by
default, but the user might reconfigure them to her liking in the
sly-mrepl-hook.
There are Sylvesters. See sly-mrepl-pop-sylvester.
If SLY detects that cl-ppcre is
available in the Lisp side it will try to use it for "apropos"
searches, otherwise the user is hinted at this possibility. As regexp
searches are slower, this is only triggered if the pattern is a valid
regular-expression.
This is the default implementation of the new
SLYNK-BACKEND:MAKE-APROPOS-MATCHER interface that particular
implementations may wish to override.
The search pattern, whether regexp-enabled or not, is now also applied to the package qualifier.
By default, SLY enables the sly-fancy meta-contrib. This contains
sly-mrepl, sly-autodoc, sly-fancy-inspector, sly-fancy-trace,
sly-fuzzy, sly-scratch, sly-package-fu, sly-fontifying-fu,
sly-trace-dialog, sly-indentation and sly-tramp.
If the user sets sly-contribs to sly-mrepl she can be sure that no
Lisp code related to other contribs appears in your run-time. Even if
ASDF is unavailable, an improved version of the slynk-loader.lisp
program will behave in a similar non-intrusive manner.
This change also enables developers to write completely independent third-party extensions like in this example.
See the CONTRIBUTING.md file for more details on architecture changes.
The SLY-DB, Inspector, XREF and Apropos buffers have been redesigned to use a common class of push button with consistent interfaces. These context-aware commands are known as "part actions"
For instance, the i,p and M-RET commands (sly-button-inspect,
sly-button-pretty-print and sly-mrepl-copy-to-repl) are available
for every interactive part, regardless of the SLY buffer in
question. A command such as v (sly-button-show-source) is only
available where it makes sense for the represented object.
The same interfaces are also available in the "mREPL" and "Trace Dialog" buffers.
sly-mode is now activated in every buffer related to SLY is now,
meaning global keybindings like C-c T and C-c I work everywhere.
Interactive commands for inspecting Lisp objects can be prefixed with
C-u to prompt the user for an inspector name. Separate inspector
streams are kept. An idea by Olof-Joachim Frahm
(http://macrolet.net/).
An experimental feature: from the Trace Dialog or SLY-DB buffers, a new button action called "Copy call to REPL" is offered and bound to
If SLY can calculate the arguments and the function symbol of the function call represented in the backtrace of trace entry, it will return them to the REPL, along with an uncommitted input line that refers back to them and calls the function.
Faces have been revised and are based on Emacs's standard faces. Hopefully, SLY will remain readable even when the user switches themes.
Popping up windows and buffers has been much improved. Windows are reused if the buffer names match or are similar, meaning that no longer will the SLY-DB "jump around" in multi-window configurations when selecting a restart that signals another error.
Interactive expression evaluation will use a separate buffer when the results is too big to fit in the echo area.
SLY's mode-line string is placed at the right side of the mode-line.
SLY intrudes less than SLIME in the Emacs name-space, and uses more
standard idioms. Macros like with-struct and sly-define-keys have
been removed.
Buffer names have been consolidated: every buffer name related to SLY obeys the same structure, stating the type, connection name and any pertinent additional info.
Reading from the minibuffer has been improved. SLY uses ido
completion by default, but it can customized via
sly-complete-symbol-function.
Messages and warnings prefix themselves accordingly with "[sly]".
Fixed source locations when recompiling from an xref buffer. This is outstanding slime/slime#175 pull-request in SLIME. Thanks Bart Botta.
Fixed bugs in contrib/sly-package-fu.el. This is the outstanding
slime/slime#145 pull-request in SLIME. Thanks
Leo Liu.
Where applicable, SLY tracks bugfixes and improvements contributed to SLIME.
SLY 1.0-Alpha supports Emacs 24.3 only. SLY 1.0 is expected to only support Emacs 24.4.
There is very limited backward compatibility SLIME and only in the SLIME->SLY direction, meaning a contrib-less SLIME may connect to a Slynk server started by SLY, but any other combination will probably fail beyond very basic functionality.
The portable profiling commands have been removed from the SLY menu
metering.lisp and the profiling interfaces in slynk-backend.lisp
have been kept. SLY 1.0.0 will hopefully have a better integrated
portable profiler.
The slime-presentations has been removed. The consistent button
interface is better.
The slime-c-p-c contrib has been removed, as it contained a lot of
non-standard window-managing code. Its functionality has been merged
into sly-fuzzy and setting sly-complete-symbol-function to
sly-c-p-c-complete-symbol should give you the previous behavior.
