|
||
Changes and New Features in development version:
|
||
|
||
* ESS[R]: Interaction with inferior process in non-R files within
|
||
packages (for instance C or C++ files) has been improved. This is
|
||
a work in progress.
|
||
|
||
* ESS[R]: 'ess-r-package-use-dir' (which sets the working directory
|
||
to the root of the current package) now works with any mode (e.g.
|
||
in C or C++ files within '/src').
|
||
|
||
* This is the last release to support Emacs older than 25.1 Going
|
||
forward, only GNU Emacs 25.1 and newer will be supported. Soon
|
||
after this release, support for older Emacs versions will be
|
||
dropped from the git master branch. Note that MELPA uses the git
|
||
master branch to produce ESS snapshots, so if you are using Emacs <
|
||
25.1 from MELPA and are unable to upgrade, you should switch to
|
||
MELPA-stable.
|
||
|
||
* ESS[R]: Long + + prompts in the inferior no longer offset output.
|
||
New option 'strip' for 'inferior-ess-replace-long+' strips the
|
||
entire + + sequence.
|
||
|
||
* ESS[R]: Fontification of roxygen '@param' keywords now supports
|
||
comma-separated parameters.
|
||
|
||
* ESS[R]: Function-like keywords such as 'if ()' or 'stop()' are no
|
||
longer fontified as keyword if not followed by an opening
|
||
parenthesis. The same holds for search path modifiers like
|
||
'library()' or 'require()'. This feature is only available in
|
||
Emacs >= 25.
|
||
|
||
* ESS[R]: We have improved fontification of keywords so they better
|
||
reflect the semantics of the R language. 'ess-R-keywords' now only
|
||
contains words reserved by the R parser.
|
||
'ess-R-control-flow-keywords' contains words of base functions that
|
||
cause non-contiguous control flow, such as 'return()' and 'stop()'.
|
||
It includes the following variables that were previously not
|
||
fontified: 'on.exit()', 'tryCatch()', 'withRestarts()',
|
||
'invokeRestart()', 'recover()' and 'browser()'
|
||
|
||
Finally, 'ess-R-signal-keywords' contains functions part of the
|
||
condition system that only potentially impact control flow:
|
||
'message()', 'warning()' (moved from 'ess-R-keywords'),
|
||
'signalCondition()' and 'withCallingHandlers()'. These keywords
|
||
inherit from 'ess-modifiers-face' (the face used for 'library()'
|
||
etc).
|
||
|
||
* ESS modes now inherit from 'prog-mode'.
|
||
|
||
* ESS[R]: The package development minor mode now only activates
|
||
within editing buffers by default, i.e. ones that inherit from
|
||
'prog-mode' or 'text-mode'. If you want to restore the old
|
||
behaviour and activate the package mode in all buffers (that have a
|
||
'default-directory' that is part of a package path), set
|
||
'ess-r-package-auto-activate' to 't'.
|
||
|
||
* ESS now provides support for flymake in R buffers for Emacs 26 and
|
||
newer. Users need to install the 'lintr' package (available on
|
||
CRAN) to use it. Customizable options include 'ess-use-flymake',
|
||
'ess-r-flymake-linters', and 'ess-r-flymake-lintr-cache'.
|
||
|
||
* Improved customization for faces. ESS now provides custom faces
|
||
for (nearly) all faces used and places face customization options
|
||
into their own group. Users can customize these options using 'M-x
|
||
customize-group RET ess-faces'.
|
||
|
||
* ESS[R]: Gained support for xref in Emacs 25+. *Note (emacs)Xref::
|
||
|
||
* ESS[R]: Changing the working directory is now always reflected in
|
||
the process buffer.
|
||
|
||
* ESS[R]: The startup screen has been cleaned up and displays the
|
||
startup directory with an explicit 'setwd()'.
|
||
|
||
* ESS now displays the language dialect in the mode-line So, for
|
||
example, R buffers will now show ESS[R] rather than ESS[S].
|
||
|
||
* The ESS manual has been updated and revised.
|
||
|
||
* ESS[R]: 'Makevars' files are now automatically opened with
|
||
'makefile-mode'.
|
||
|
||
* New varaible 'ess-write-to-dribble'. This allows users to disable
|
||
the dribble ('*ESS*') buffer if they wish.
|
||
|
||
* ESS now respects Emacs conventions for keybindings. This means
|
||
that The 'C-c [letter]' bindings have been removed. This affects
|
||
'C-c h', which was bound to 'ess-eval-line-and-step-invisibly' in
|
||
'sas-mode-local-map'; 'C-c f', which was bound to
|
||
'ess-insert-function-outline' in 'ess-add-MM-keys'; and 'C-c h',
|
||
which was bound to 'ess-handy-commands' in 'Rd-mode-map',
|
||
'ess-noweb-minor-mode-map', and 'ess-help-mode-map'
|
||
|
||
* prettify-symbols-mode no longer breaks indentation This is
|
||
accomplished by having the pretty symbols occupy the same number of
|
||
characters as their non-pretty cousins. You may customize the new
|
||
variable 'ess-r-prettify-symbols' to control this behavior.
|
||
|
||
* Variable 'ess-s-versions-list' is obsolete and ignored. Use
|
||
'ess-s-versions' instead. You may pass arguments by starting the
|
||
inferior process with the universal argument.
|
||
|
||
* The 'ess-r-args.el' library has obsoleted and will be removed in a
|
||
future release. Use 'eldoc-mode' instead, which is on by default.
|
||
|
||
* All of the '*-program-name' variables have been renamed to
|
||
'*-program'. Users who previously customized e.g.
|
||
'inferior-ess-R-program-name' will need to update their
|
||
customization to 'inferior-ess-R-program'. These variables are
|
||
treated as risky variables.
|
||
|
||
* 'ess-smart-S-assign' changed name to 'ess-insert-S-assign'. By
|
||
default, it provides similar functionality. Since many users
|
||
dislike this functionality, it is easier to disable; set
|
||
'ess-smart-S-assign-key' to nil. The following functions have been
|
||
made obsolete and will be removed in the next release of ESS:
|
||
ess-smart-S-assign, ess-toggle-S-assign, ess-toggle-S-assign-key,
|
||
ess-disable-smart-S-assign.
|
||
|
||
* The option ess-S-assign has been removed. Customize new option
|
||
'ess-assign-list' instead.
|
||
|
||
* 'C-c C-=' is now bound to 'ess-cycle-assignment' by default See the
|
||
docstring for details. New user customization option
|
||
'ess-assign-list' controls what assignment operators are cycled
|
||
through.
|
||
|
||
* The ESS initialization process has been further streamlined. If
|
||
you update the autoloads (which installation from 'package-install'
|
||
does), you should not need to '(require 'ess-site)' at all, as
|
||
autoloads should automatically load ESS when it is needed (e.g.
|
||
the first time an R buffer is opened). In order to defer loading
|
||
your ESS config, you may want to do something like
|
||
'(with-require-after-load "ess" <ess-config-here>)' in your Emacs
|
||
init file. Users of the popular 'use-package' Emacs package can
|
||
now do '(use-package ess :defer t)' to take advantage of this
|
||
behavior.
|
||
|
||
Changes and New Features in 17.11:
|
||
|
||
* The ESS initialisation process has been streamlined. You can now
|
||
load the R and Stata modes independently from the rest of ESS. Just
|
||
put '(require 'ess-r-mode)' or '(require 'ess-stata-mode)' in your
|
||
init file. This is for experienced Emacs users as this requires
|
||
setting up autoloads for '.R' files manually. We will keep
|
||
maintaining 'ess-site' for easy loading of all ESS features.
|
||
|
||
* Reloading and quitting the process is now more robust. If no
|
||
process is attached, ESS now switches automatically to one
|
||
(prompting you for selection if there are several running).
|
||
Reloading and quitting will now work during a debug session or when
|
||
R is prompting for input (for instance after a crash). Finally,
|
||
the window configuration is saved and restored after reloading to
|
||
prevent the buffer of the new process from capturing the cursor.
|
||
|
||
* ESS[R]: New command 'ess-r-package-use-dir'. It sets the working
|
||
directory of the current process to the current package directory.
|
||
|
||
* ESS[R] Lookup for references in inferior buffers has been improved.
|
||
New variable 'ess-r-package-source-roots' contains package
|
||
sub-directories which are searched recursively during the file
|
||
lookup point. Directories in 'ess-tracebug-search-path' are now
|
||
also searched recursively.
|
||
|
||
* ESS[R] Namespaced evaluation is now automatically enabled only in
|
||
the 'R/' directory. This way ESS will not attempt to update
|
||
function definitions from a package if you are working from e.g. a
|
||
test file.
|
||
|
||
Changes and New Features in 16.10:
|
||
|
||
* ESS[R]: Syntax highlighting is now more consistent. Backquoted
|
||
names are not fontified as strings (since they really are
|
||
identifiers). Furthermore they are now correctly recognised when
|
||
they are function definitions or function calls.
|
||
* ESS[R]: Backquoted names and '%op%' operators are recognised as
|
||
sexp. This is useful for code navigation, e.g. with 'C-M-f' and
|
||
'C-M-b'.
|
||
* ESS[R]: Integration of outline mode with roxygen examples fields.
|
||
You can use outline mode's code folding commands to fold the
|
||
examples field. This is especially nice to use with well
|
||
documented packages with long examples set. Set
|
||
'ess-roxy-fold-examples' to non-nil to automatically fold the
|
||
examples field when you open a buffer.
|
||
* ESS[R]: New experimental feature: syntax highlighting in roxygen
|
||
examples fields. This is turned off by default. Set
|
||
'ess-roxy-fontify-examples' to non-nil to try it out.
|
||
* ESS[R]: New package development command 'ess-r-devtools-ask' bound
|
||
to 'C-c C-w C-a'. It asks with completion for any devtools command
|
||
that takes 'pkg' as argument.
|
||
* ESS[R]: New command 'C-c C-e C-r' to reload the inferior process.
|
||
Currently only implemented for R. The R method runs
|
||
'inferior-ess-r-reload-hook' on reloading.
|
||
* ESS[R]: 'ess-r-package-mode' is now activated in non-file buffers
|
||
as well.
|
||
|
||
Bug fixes in 16.10:
|
||
* ESS[R]: Fix broken (un)flagging for debugging inside packages
|
||
* ESS[R]: Fixes (and improvements) in Package development
|
||
* ESS[R]: Completion no longer produces '...=' inside 'list( )'.
|
||
* ESS[R]: Better debugging and tracing in packages.
|
||
* ESS[R]: Better detection of symbols at point.
|
||
* ESS[R]: No more spurious warnings on deletion of temporary files.
|
||
* ESS[julia]: help and completion work (better)
|
||
* ESS[julia]: available via 'ess-remote'
|
||
|
||
Changes and New Features in 16.04:
|
||
|
||
* ESS[R]: 'developer' functionality has been refactored. The new
|
||
user interface consists of a single command
|
||
'ess-r-set-evaluation-env' bound by default to 'C-c C-t C-s'. Once
|
||
an evaluation environment has been set with, all subsequent ESS
|
||
evaluation will source the code into that environment. By default,
|
||
for file within R packages the evaluation environment is set to the
|
||
package environment. Set 'ess-r-package-auto-set-evaluation-env'
|
||
to 'nil' to disable this.
|
||
* ESS[R]: New 'ess-r-package-mode' This development mode provides
|
||
features to make package development easier. Currently, most of
|
||
the commands are based on the 'devtools' packages and are
|
||
accessible with 'C-c C-w' prefix. See the documentation of
|
||
'ess-r-package-mode' function for all available commands. With
|
||
'C-u' prefix each command asks for extra arguments to the
|
||
underlying devtools function. This mode is automatically enabled
|
||
in all files within R packages and is indicated with '[pkg:NAME]'
|
||
in the mode-line.
|
||
* ESS[R]: Help lookup has been improved. It is now possible to get
|
||
help for namespaced objects such as pkg::foobar. Furthermore, ESS
|
||
recognizes more reliably when you change 'options('html_type')'.
|
||
* ESS[R]: New specialized breakpoints for debugging magrittr pipes
|
||
* ESS: ESS now implements a simple message passing interface to
|
||
communicate between ESS and inferior process.
|
||
|
||
Bug fixes in 16.04:
|
||
* ESS[R]: Roxygen blocks with backtics are now correctly filled
|
||
* ESS[R]: Don't skip breakpoints in magrittr's 'debug_pipe'
|
||
* ESS[R]: Error highlighting now understands 'testthat' type errors
|
||
* ESS[Julia]: Added getwd and setwd generic commands
