CHANGELOG (37230B)

 # -*- mode: org -*-
 * v0.6.0    2024-03-21
 
 - On Emacs 28.1 and later, all infix commands and suffix commands
   that are defined inline (i.e., using a lambda when defining a prefix
   command), are now hidden from ~execute-extended-command~ (aka ~M-x~) /by
   default/.  It was already possible to hide these commands, but users
   had to opt-in explicitly.  After refactoring how these commands are
   declared to be unsuitable for ~M-x~, it is now possible to hide them
   /without/ also hiding other, unrelated kinds of unsuitable commands.
 
   I recommend that you instruct to hide /all/ unsuitable command.
   This requires that you customizing ~read-extended-command-predicate~,
   because the Emacs authors have decided that this should be an opt-in
   feature.
 
   Note that this has no effect on Emacs releases before 28.1.
 
 - Added documentation stating that ~:class~ has to be specified when
   using ~:setup-children~.  beecdc85
 
 - Added a new prefix slot ~column-widths~, which can be used to specify
   the minimal width of each column in all ~transient-columns~ groups of
   that prefix.  92e8952e
 
 - When assigning a name to a suffix that is defined inline, we no
   longer use the suffix description, iff that would result in an
   overly long name.  81a108ba
 
 - Functions used as the value of face slots can now take one
   argument, the suffix object.  Functions that take zero arguments
   are still supported.  Additionally, ~transient--pending-suffix~ is
   bound around calls to these functions, but it is better to pass
   the object as an argument.  f582a9bc
 
 - The new ~definition~ suffix slot can be used to specify a default
   function definition that is used if no function body is provided
   using ~transient-define-suffix~.  5b334a51
 
 - Taught ~transient-suffix-object~ about ~transient--pending-suffix~.
   20a3770d
 
 Bug fixes:
 
 - If ~transient-parse-suffix~ and ~transient-parse-suffixes~ are called
   with an invalid value for their ~prefix~ argument, they failed to
   detect that.  03e752d9
 
 - If ~nil~ is encountered inside a group specification, that was
   silently ignored.  Now an error is signaled.  8c01a1eb
 
 - ~find-function~ wasn't able to locate the definitions of infix
   commands anymore.  a30df67b
 
 - There was no binding for ~ignore-preserving-kill-region~ in
   ~transient-predicate-map~.  0fc87002
 
 - Invoking a non-symbolic non-suffix command, caused an error.
   bd2a5ea0
 
 - When a group begins with an included subgroup, that affected what
   group class was assumed, in the absence of an explicit specification.
   df36bc87
 
 - ~transient--suspend-override~ failed to move out of the minibuffer
   before refreshing the transient buffer.  833143ba
 
 - When a suffix command signaled an error during a trivial phase
   (which does not involve, e.g., the minibuffer), then the transient
   window was not deleted when the debugger was entered.  9d8f361f
 
 - When a prefix was refreshed, the wrong color was used for suffix
   commands that exit the prefix, indicating that would cause a return
   to the outer prefix, even though there is none.  f51c144a
 
 - Calling ~transient-infix-read~ with an invalid value, resulted in
   a confusing error.  Now an appropriate error is used.  3ebb6acf
 
 - When third-party code or user customization managed to display
   another buffer in our dedicated window, then that buffer got
   killed when we tried to kill the transient buffer.  #271
 
 * v0.5.3    2023-12-16
 
 - Fixed regression when setting ~:pad-keys~ for a ~transient-columns~
   group.  #269
 
 * v0.5.2    2023-12-05
 
 - Fixed formatting issues in the manual.
 
 * v0.5.1    2023-12-05
 
 - Added a new introduction by JD Smith (@jdtsmith).
 
 Bug fixes:
 
 - Faces that use a box are now defined more defensively to protect
   against unexpected values and provide reasonable fallback colors.
   413310cd, b8aefce3
 
 - Only prepare to return to the parent transient if there actually is
   a parent.  The only negative effect of failing to do this was that
   the suffix was colored wrong, since ~transient--do-return~ falls back
   to behave like ~transient--do-exit~.  5f2cfc9f
 
 * v0.5.0    2023-11-28
 
 - Some suffix commands exit the transient from which they were
   invoked, while others don't (allowing the user to invoke another
   suffix without first having to enter the transient again).
 
   Until now it wasn't possible to tell which category any given suffix
   falls into, at least not by default.  Now the key binding of each
   suffix is colorized to indicate its transient behavior.  Red means
   that the suffix exits the transient, and blue means that it does
   not.  Keys for suffixes that currently cannot be invoked are gray.
 
   Likewise, the thin line, that is drawn between the transient popup
   buffer and the minibuffer, is used to indicate what happens, if you
   invoke a command that is not a suffix.  Most prefixes do not allow
   non-suffixes to be invoked, so this line usually is gray.  c8a9ac51
 
 - Many faces have also been improved.  This involves changing which
   built-in faces they inherit from, some explicit changes to their
   appearance, and semantic clarifications.  Of course your mileage may
   vary — it's possible that some face just happened to look right with
   your chosen theme, but now it has to be themed to achieve that
   again.  47d3f01d 71d16d86 et al.
 
 - Added a new face, ~transient-delimiter~, which is used for parentheses
   around values and the pipe character used to separate possible values
   from each other.  567b5d54
 
 - Added a new command ~transient-toggle-level-limit~, bound to ~C-x a~,
   which temporarily shows all suffix commands a transient has to
   offer.  This makes it possible to occasionally use more obscure
   commands and arguments, without having to always display them.
   For more information see [[https://magit.vc/manual/transient/Enabling-and-Disabling-Suffixes.html][Enabling and Disabling Suffixes]].  #243
 
 The changes described below, only directly affect package authors and
 users who implement their own transients.  If that does not describe
 you, then all you have to know is that many features were fine-tuned
 and otherwise improved, opening up some new use-cases and making some
 things easier to implement.  This will hopefully lead to improvements
 in your favorite transient-using packages in the coming months.
 
 - It sometimes makes sense to bind multiple keys to the same suffix
   command, e.g., because they behave differently based on the suffix
   description, or some other slot that can be set per binding.
   Previously these bindings shared a visibility level; how this can
   be set individually.  #153
 
 - While functions are run, which format strings to be inserted into the
   transient buffer or to determine whether other aspects of a suffix,
   that transient buffer no longer is the current buffer.  Instead the
   buffer in which the prefix and its suffixes operate, is the current
   buffer.  This affects functions such as ~transient-format-description~
   and those found in predicate slots such as ~if~.  In contexts where
   the transient buffer is needed but the other buffer happens to be
   current, the new macro ~transient-with-shadowed-buffer~ can be used
   to temporarily change that.
 
 - The new suffix slots ~face~ and ~inapt-face~ can be used to specify how
   a suffix looks, which in simple cases is more convenient than using
   a function as ~description~ and adding the face there.  The values of
   these slots should be faces or functions that returns a face.  The
   default for ~inapt-face~ is ~transient-inapt-suffix~, but in some cases
   it is undesirable to apply this face to the whole description, so
   this can be overridden by setting this slot to ~nil~ for individual
   suffixes.  The default for ~face~ is ~nil~.  c2a75880 8e15a29b 71399d21
 
 - Added new variables ~transient--pending-suffix~ and
   ~transient--pending-group~, which are bound while a suffix/group is
   being inserted.  These are mostly intended for internal purposes,
   but in some rare complex cases package authors might need them too.
   0717589a 70e8dc80
 
 - Sometimes it is useful to display some information in the transient
   buffer, which is not associated with a suffix command.  The new
   class ~transient-info~ can be used for that purpose.  Children that
   use this class are very similar to regular suffixes, the lack of a
   command binding being nearly the only difference.  #226
 
 - Instead of a list of choices, the value of a suffix's ~choices~ slot
   can now be a function that returns such a list.  #212
 
 - Per-suffix functions that format its description (specified using the
   ~description~ slot) can now optionally take one instead of zero argument,
   the respective suffix object.  09be367b
 
 - Added a new command ~transient-echo-arguments~ intended for use in
   examples and bug reports, when a prefix must bind some command, but it
   does not really matter which.  Using this command is less verbose than
   having to implement a dummy every time, and it comes with some goodies.
   I.e., it reports information about the prefix from which it was invoked.
   faa3d09d
 
 - When a command was defined using ~transient-define-suffix~ and an alias
   for that command was created using ~defalias~, then the alias had no
   access to the associated suffix object.  Now it does, which makes it
   possible to bind the same command multiple times in a prefix, and make
   it behave differently depending on the symbol-name that was used to
   invoke it.  f43aee1a
 
 - The values of a prefix's ~transient-suffix~ and ~transient-non-suffix~
   slots should now be a boolean.  The value of the ~transient-suffix~
   slot has to be handled differently for different types of suffixes.
   I.e., infix arguments must ignore it, and sub-prefixes must honor
   it but to do so they must use a different pre-command.  Previously
   booleans were not supported and the previously recommended values,
   ~transient--do-stay~ and ~transient--do-exit~ are still supported (but
   they are "corrected" for sub-prefixes).  For the ~transient~ slot the
   use of booleans was always allowed and recommended.  8098d175
 
 - For sub-prefixes a value of ~t~ for the ~transient-suffix~ slot of the
   parent prefix now means that suffixes, which exit the sub-prefix,
   return to the parent prefix, instead of exiting that as well.
   784887b7 5ad5b627
 
 - In addition to booleans and pre-commands, the values of the
   ~transient-suffix~, ~transient-non-suffix~ and ~transient~ slots
   may now also be pre-command "shorthands", e.g., use ~leave~ instead
   of ~transient--do-leave~ (which in some cases is a good value for
   `transient-non-suffix`). 9617b6c7
 
 - ~transient--do-replace~ now behaves as documented and implied by its
   name.  Use the new ~transient--do-stack~ if you want to return to the
   outer prefix.  94661e0c
 
 - Added a new prefix slot ~transient-switch-frame~, which allows
   specifying the transient behavior of ~switch-frame~ per prefix and
   independently of the transient behavior of other non-suffixes
   (specified using the ~transient-non-suffix~ slot).  609dabfd
 
 - Added a new function ~transient-prefix-object~ to allow package
   authors to avoid the following unfortunate complication.
 
   While a transient is being setup or refreshed (which involves
   preparing its suffixes) the variable ~transient--prefix~ can be
   used to access the prefix object.  Thus this is what has to be
   used in suffix methods such as ~transient-format-description~,
   and in object-specific functions that are stored in suffix slots
   such as ~description~.  When a suffix command is invoked (i.e.,
   in its ~interactive~ form and function body) then the variable
   ~transient-current-prefix~ has to be used instead.
 
   Two distinct variables are needed, because any prefix may itself
   be used as a suffix of another prefix, and such sub-prefixes have
   to be able to tell themselves apart from the prefix they were
   invoked from.  Regular suffix commands, which are not prefixes, do
   not have to concern themselves with this distinction, so they can
   use this function instead.  In the context of a plain suffix, it
   always returns the value of the appropriate variable.
   37307c1b

 This release drops support for Emacs 25.  The last Emacs 25 release
 (25.3) was released in 2017; over six years ago.  The current Emacs
 version is 29.1; that's four major releases since 25.1.
 
 * v0.4.3    2023-08-25
 
 - Added a second implementation of ~transient--wrap-command~, taking
   advantage of improvements in Emacs 30.
 
 * v0.4.2    2023-08-25
 
 - Infix commands are only useful when invoked from a transient prefix
   command and ~execute-extended-command~ should not offer them as
   completion candidates.  In the past we used a weird kludge to
   accomplish that, but now we rely on ~read-extended-command-predicate~.
   That allowed the removal of some complications and made it possible
   to fix a bug in ~transient--wrap-command~.
 
   To hide infix commands, users now have to update to Emacs 28, or
   later, and customize ~read-extended-command-predicate~.
 
   #+begin_src emacs-lisp
     (setq read-extended-command-predicate
           'command-completion-default-include-p)
   #+end_src
 
 - Due to changes in Emacs 29.1, pretty-printing isn't consistent
   across Emacs releases anymore by default, which is unfortunate
   in our case because we use it to write to files that are likely
   to be checked into version control.  We now force the use of the
   old style across releases.
 
 * v0.4.1    2023-06-02
 
 Bug fixes:
 
 - 070d47b0 Support searches that end right after suffix
 - ab831828 transient--insert-group(columns): Drop separator before first column
 - 62edeffd #247 Fix bug using :incompatible using suffixes before infixes
 - 6efa9fad transient-predicate-map: Bind univeral-argument-more
 
 * v0.4.0    2023-05-10
 
 - Transient has to update state after every suffix command.  If that
   fails for some reason, then Emacs ends up in an badly broken state.
   It was rare, but in the worst case scenario, that meant that Emacs
   refused to call any more commands and had to be killed.
 
   Naturally ~post-command-hook~ is the first choice to run something
   after commands, but unfortunately that hook is not guaranteed to run
   only once, and worse it is not guaranteed run /after/ the command.
   Working around this limitation made an essential part of Transient
   much more complex and fragile.  As new edge-cases were discovered,
   new and increasingly desperate heuristics had to be added, until I
   finally decided that relying solely on hooks was just not feasible.
 
   Now ~pre-command-hook~ is used to advice ~this-command~, to add an
   around advice, which ensures that the state update takes place, even
   when ~post-command-hook~ is run prematurely.  The advice wraps both
   the function body and the interactive spec with ~unwind-protect~, so
   we can finally be sure that the state change is always performed,
   and that the advice is removed again.
 
   It has been an interesting journey, and I have documented it in long
   commit messages.  If you are interested in the details, see 7b8a7d71
   (which still tries to avoid using any advice), 51c68c87, 52cac9c0,
   bug#61179 and bug#61176.
 
 - The ~transient-define-prefix~ now expands to code instead of data,
   meaning that lambda expressions are finally properly evaluated and
   byte-compiled.  ea851f3b e88f51d6 277e5f2d a1774182
 
 - Popup navigation is no longer considered a second-class feature and
   is enabled by default.  Some transients allow arbitrary non-suffixes
   to be invoked, so some key bindings, which were previously used for
   popup navigation, had to be removed, to avoid conflicts.  98d50202 ff
 
 - Each prefix and suffix can now have its own help function.  This is
   configured using the new ~show-help~ slot.  ea5ac99f
 
 - The ~transient-options~ class now supports two types of options that
   can have multiple values: repeated option-value pairs and a final
   option that takes all remaining arguments as value.  #154
 
 - Added support for the use of non-proportional text in the transient
   popup.  7f5520b3
 
 - Imenu was taught about Transient's definition macros.  #178
 
 - It is now possible to return to the parent prefix from a sub-prefix.
   e90f7a16
 
 - Boolean values of the ~transient~ slot of sub-prefixes are now
   interpreted correctly.  4a36b1d9
 
 - Added new option ~transient-hide-during-minibuffer-read~.  5762bd9a
 
 - Added new option ~transient-align-variable-pitch~.  cda6a120
 
 - Added new command ~transient-reset~, which clears the set and saved
   value of the active transient.  51585b8d
 
 - When using Emacs 28, ~execute-extended-command~ can be told to ignore
   transient infix commands.  Even when using that Emacs version, that
   command does not ignore any commands by default, but this behavior
   can be easily be enabled using:
 
     (setq read-extended-command-predicate
           'command-completion-default-include-p)
 
   Infix arguments are implemented as commands, so they by default show
   up as completion candidates of ~execute-extended-command~, which is
   useless because they are only intended to be invoked from transient
   prefix commands.  Enable this feature to prevent that.
 
 - Added new command ~transient-toggle-debug~.  b466cd9a
 
 - Depend on the Compat package, allowing me to use convenient features
   that were added to Emacs over the last few years, without having to
   wait another few years until everybody has updated to a reasonably
   recent Emacs release.  5ae3c401
 
 - Added basic support for suffixes that span multiple lines (multi-row
   cells).  #193
 
 - Infix arguments can now be invoked following a prefix argument.  To
   use a negative prefix argument use "C--".  "-" cannot be used anymore
   because it conflicts with the most common prefix key used for infix
   arguments.  ed2febd0
 
 - Removed obsolete aliases for functions deprecated in v0.3.0.  #192
 
 - Duplicated suffix commands are now disambiguated, making it possible
   to bind a command multiple times as a suffix of a transient command,
   but still have it do different things depending on what binding is
   used, based on the value of some slot of the corresponding suffix
   object, similar to how ~self-insert-command~ inserts the pressed key.
   f27c840a
 
 - ~recursive-edit~ and ~top-level~ can now be used while a transient is
   active.  fcdeadc1 5a1b2bac
 
 - Switched to Emacs 29's new keymap functions, which are also supported
   in newer releases, thanks to the Compat package.  87f70af5 5a966aa8

 * v0.3.7    2021-10-25
 
 - Added an additional safety hatch to prevent Emacs from entering an
   inconsistent state when an unexpected error occurs.  99e48369
 
 - Added support for implementing section movement commands in
   third-party packages.  This was requested by the maintainer of
   Emacspeak.  Because they would be of very limited use to sighted
   users no such commands are added to Transient itself.  769219b5
 
 - ~transient-read-number-{N0,N+,N}~ now support infix arguments that
   have three different states: disabled, enabled without an empty
   value, and enabled with a non-empty value.  626d105e
 
 - If a command is called as a suffix of itself, then the help command
   shows the function definition instead of the man-page as it usually
   does for prefixes.  e17e2b2f
 
 - Give users more control over how the transient buffer is displayed.
   Various aspects that were previously hardcoded can now be changed
   using the ~transient-display-buffer-action~ option.  7c677737
 
 - Added support for adding suffixes that might be neither defined nor
   autoloaded when the prefix is invoked.  This usually results in an
   error and while it is now possible to override that using an extra
   step, it is still discouraged.  6842305e
 
 Bug fixes:
 
 - 1e740608 transient-map: Bind C-u to universal-argument
 - e9048100 Explicitly call transient--pre-command in button action

 Also contains various documentation updates and code clean-ups.
 
 * v0.3.6    2021-07-01
 
 - Added new option ~transient-force-single-column~, which may be useful
   for low vision.  #122
 
 - Added new option ~transient-highlight-higher-levels~, which is
   intended for package authors.  90a05622
 
 * v0.3.5    2021-06-16
 
 - Added a kludge to work around some unexpected Emacs behavior.
   ef921d30
 
 - When showing help for a suffix that is also a subprefix, then also
   consider the manpage that is set for the prefix, if any.  a9bdd013
 
 * v0.3.4    2021-05-25
 
 - Very minor changes.
 
 * v0.3.3    2021-05-24
 
 - Added SPDX-License-Identifier library header.  7d3d8d79
 
 * v0.3.2    2021-04-20
 
 - Fixed an error message.  c145229a
 
 * v0.3.1    2021-04-19
 
 - Changed ~transient-prefix~'s ~suffix-description~ slot to be initially
   unbound, as was always intended.  c28b8a4
 
 - Added new functions ~transient-read-file~ and
   ~transient-read-existing-file~.  a3b44224
 
 * v0.3.0    2021-02-21
 
 - Added a temporary kludge to prevent a transient from being invoked
   while the minibuffer is active.  A future release will enable
   this again, once we are sure that cannot cause Emacs to enter an
   inconsistent state, that causes most events to be ignored.  #112
 
 - Improved the backtrace that is shown when a fatal error occurred in a
   critical context.  This involved some back and forth.  See commits
   mentioning the "emergency exit".
 
 - Added support for defining a per-prefix fallback suffix description
   function, which is used for suffixes that do not explicitly provide
   a description.  The new ~suffix-description~ slot is used to specify
   that function.  The new ~transient-command-summary-or-name~ function
   is useful, not just as an example.  8b22b52b
 
 - Added ~transient-arg-value~, which can be used to extract the values
   of individual arguments in the output of ~transient-args~.  d76f73f8
 
 - Added support for using variables in group and suffix definitions
   of a prefix.  Such indirect specifications are resolved when the
   transient prefix is being defined.  #101
 
 - No longer bind ~M-<key>~ to any common suffix commands; freeing this
   namespace for a variety of uses in individual transient.  A few
   existing bindings had to be changed because of this.  990eb0a2
 
 - Added ~transient-suffixes~ function, which is useful when
   ~transient-args~ is not sufficient because one needs the suffix
   objects, not just their values.  #98
 
 - Added ~init-value~ slot for infix and prefix objects.  If this value
   bound then it is called with the object as only argument instead of
   the primary ~transient-init-value~ method of the object class.  #96,
   3284f6a0
 
 - Added ~unsavable~ slot for infix objects.  If this is non-nil, then
   the value of the infix is removed from the prefix value before
   saving, setting and adding to history.  #96
 
 - Added support for right padding the keys of all suffixes in a group.
   This is controlled using the new ~pad-keys~ slot of group objects.
   7502390b, 293a437d
 
 - Added support for delaying setup of the suffixes of a prefix until
   that is invoked.  Also added support for using unnamed functions as
   suffix commands.  Taken together these changes make it possible to
   dynamically create the list of suffixed.  See the ~notmuch-transient~
   package for two examples: ~notmuch-search-transient~ and
   ~notmuch-tag-transient~.  f2252d53, a3e53633
 
 - Added the infix class ~transient-lisp-variable~.  2d8ceff4
 
 - Added ~transient-infix-read~, which allows arbitrary commands to read
   a value the same way as would the infix command that is provided as
   an argument to this function.  73694be4
 
 - Added support for coloring suffixes in a Hydra-like fashion.
   To enable this, customize option ~transient-semantic-coloring~.
   248862c5
 
 - Added support for disabling and dimming suffix commands that are
   currently not suitable, instead of completely hidding them.  #80
 
 - Autoload functions that serve a purpose similar to that of
   ~define-key~. #85
 
 - Consistently use ~transient-~ as the prefix of all symbols.
   The old names remain available as obsolete aliases.  dd0c44cb
 
 - Added support for scrolling the transient popup buffer using the
   scroll bar.  #84
 
 - Various bug fixes.

 * v0.2.0    2020-02-26
 
 - ~transient-args~ must now be called with a transient prefix command
   as argument.  It is now the only argument and its value must be a
   symbol now, an object is no longer supported.  When this command
   does not match ~current-transient-command~, then this function now
   returns the set, saved or default value.  0312b93, 7d0db28,
   d33fe5a, a6ce195
 
 - No longer use the last history element as initial minibuffer input
   by default.  Added new option ~transient-read-with-initial-input~ to
   allow users to restore the old default. dcf7a4d, 5decc6e
 
 - The set and saved values were not always used.  #68
 
 - Added support for inserting and removing groups.  #36
 
 - Added support for specifying where to insert elements and groups
   using coordinates.  #26
 
 - Added support for moving the cursor inside the transient popup
   buffer using the arrow keys or Isearch, and for invoke suffix
   commands using RET or mouse clicks.  Unlike Magit-Popup, Transient
   doesn't make the transient popup buffer the current buffer.  This
   is important when invoking suffix commands that take the current
   position into account, but it has the drawback that we do not get
   these features for free.  Because I also consider them unnecessary
   I did not implement them initially.  Turns out quite a few users
   strongly disagree.  Set ~transient-enable-popup-navigation~ to ~t~ to
   enable these features.  #42
 
 - Explicitly support Edebug.  Previously when Edebug was triggered
   while a transient was active, then Emacs entered an unrecoverable
   state.  #19
 
 - No longer attempt to display a thin line in termcap frames.  0a96a57
 
 - Work around some Ivy bugs/incompatibilities.  af243d5, fed7ab1
 
 - The new option ~transient-force-fixed-pitch~ allows users to use a
   monospaced font in transient's popup buffer even if they use a
   proportional font for the rest of Emacs.  #25, #67
 
 - Adapted to backward incompatible changes in Emacs 27 that prevented
   faces from extending to the edge of the window as expected.  c1ae1ee
 
 - No longer depend on dash (or any other third-party package).  #66
 
 - When a transient has conflicting key bindings and Transient is
   configure to warn about that, then Emacs entered an unrecoverable
   state instead.  75de1f0
 
 - ~transient-format-value~ now supports options with multiple values.
   #65
 
 - Removing a suffix based on its position was broken.  41cbf49
 
 - In our popup buffers disable the tab feature that Emacs 27
   introduces.  #62
 
 - Inserting a new suffix next to another ended up replacing the latter
   instead if its key binding was defined in the suffix object.  #58
 
 - ~transient-undefined~ learned to make some noise.  #57
 
 - Fix replacing a suffix with another suffix bound to the same key.
   5a360bb, 4ce1868
 
 - Characters are no longer allowed as pseudo suffixes.  To insert a
   an empty cell into a table use the empty string instead.  71687ba
 
 - Added new variable ~transient--buffer-name~.  #45
 
 - Some misconfiguration that affects how the transient popup buffer
   is displayed could lead to Emacs entering an unrecoverable state.
   #34, #44
 
 - The echo area is now cleared when the transient popup buffer is
   shown.  afdf1f0
 
 - If ~transient-show-popup~ is 0 or a negative number, then not even
   a one-line summary is shown initially.  #41
 
 - Added new function ~transient-read-directory~.  a87cb2c
 
 - ~define-transient-command~ now supports specifying the level of a
   suffix using the ~:level~ keyword argument.  6506cfd
 
 - The mode-related suffix predicates now also support a list of modes
   as argument in addition to a single mode as before.  1c6afb8
 
 - The new ~incompatible~ slot of prefix objects makes it possible to
   specify which arguments should be autoatically disabled when the
   user enables certain other arguments.  544b3bb
 
 - ~transient--history-push~ is now defined as generic function.  47b7975
 
 - The a new ~history-key~ slot and ~transient--history-key~ generic
   function for prefix objects.  3668aeb, e627d45
 
 - Disallow setting the level of essential suffixes that are shared
   between all transients.  #29
 
 - The active infix is now highlight while reading its value from the
   user.  #30
 
 - The commands ~transient-set~  and ~transient-save~ can now be configured
   to exit the transient, though by default they still don't.  a47ae94
 
 - Always respect the ~transient~ slot of a suffix, even if that suffix
   has a binding in ~transient-predicate-map~.  919fc66
 
 - Added new generic functions ~transient-set-value~ and
   ~transient-save-value~ intended for prefix commands.  ebe9d9d
 
 - It is no longer possible to set a prefix level to 0, which is an
   invalid value.  #28
 
 - All transient prefix and suffix commands are now automatically
   declared to be for interactive use only.  a6295fa
 
 - Infix arguments are no longer added to ~command-history~ because
   these entries were both useless and extremely noisy.  #23
 
 - ~digit-argument~ no longer exits the transient.  5f0ec7d
 
 - A new keymap, ~transient-base-map~ was added to make it easier to
   change key bindings that are shared between all transients.  This
   new keymap is used as the parent of all the other keymaps that are
   shared between all transients.
 
 - Added new commands ~transient-scroll-up~ and ~transient-scroll-down~,
   which scroll the transient window.  ~C-v~ and ~M-v~ (and ~<next>~ and
   ~<prior>~) are bound to these commands.  These keys were chosen they
   are bound to scrolling commands in the global map too.  This made
   it necessary to find a new binding for ~transient-show~, which ~C-t~ is
   bound to now.  #17
 
 - The new option ~transient-mode-line-format~ allows users to use
   a mode-line for the transient popup buffer instead of just a
   thin line that separates it from the echo area.  When using a
   non-standard value for ~transient-display-buffer-action~ it may
   be necessary to do that.  #17
 
 - The new option ~transient-display-buffer-action~ allows users to
   specify how a window is selected to display the transient popup
   buffer.  The ~lv~ library is no longer used.  #17
 
 - The window that was selected before the transient window was shown
   is no longer re-selected before calling a suffix that exits the
   transient.  If a suffix changes the selected window unintentionally,
   then that is a bug.  This makes it possible to intentionally change
   the window layout using transients.
 
 - An infix is a special kind of suffix.  Depending on context
   "suffixes" means "suffixes (including infixes)" or "non-infix
   suffixes".  This is now mention in a few places where users might
   otherwise get confused.
 
 - Stopped claiming that the transient is shown in the "echo area",
   because technically that is not correct.  Instead talk about the
   "popup buffer".
 
 - Fixed handling of suffix commands that are undefined at the time the
   prefix is invoked.  This is still an error, but the error message
   now explains what is wrong.  a729bbb
 
 - Fixed saving values/history/levels, making sure that the printed
   expression is never abbreviated.  #15
 
 - Fixed jumping to the correct place in a manpage when showing the
   documentation for an infix argument.  c4bf4af
 
 - Bound ~ESC ESC ESC~ to ~transient-quit-all~ because the convention is
   that it should be possible to exit any temporary state using this
   binding.  #12
 
 - Fixed referencing suffix bindings by their key when the key binding
   is defined in the suffix object instead of in the suffix spec.
   e4ffb97
 
 - Remove trailing whitespace from popup text for the benefit of users
   who have set enabled ~show-trailing-whitespace~ globally.  0758efa
 
 - Fixed showing available bindings on a single line instead of using
   the usual popup buffer.  2f011c9, 99d3bf6
 
 - Added a line between the ~lv~ window and the echo area.  ca18bb6
 
 - Fixed adding a new suffix at the end of a group and removing a
   group's last suffix.  #20, #6
 
 - No longer use ~cl-typep~, which appears to have a bug on Emacs 25.
   9183fe1
 
 - Fixed ~lisp~ make target.  170a3fd
 
 - Fixed reading a number as the value of an infix.  8219c0b
 
 - Various bug fixes to
   ~transient--goto-argument-description~ (4f80a89),
   ~transient-show-help~ (ccac95e),
   ~transient-infix-read~ (7bf9759).
 
 * v0.1.0    2019-01-14
 
 - First release.
