Version 24.1.1 of package Ess has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Ess describes itself as: ======================= Emacs Speaks Statistics ======================= More at https://elpa.gnu.org/packages/ess.html ## Summary: Emacs Speaks Statistics (ESS) is a package designed to support editing of scripts and interaction with various statistical analysis programs such as R, S-Plus, SAS, Stata and OpenBUGS/JAGS. For more details please visit ESS home ## Recent NEWS: Changes and New Features in 24.01.1: • Revert a bug introduced with the ‘ess-request-a-process’ change Changes and New Features in 24.01.0: • fix docstring warnings in ess-custom • :package-version is now set to "VERSION" in ess-custom. By make this is replaced with "24.01.0" (or similar). • Better “collaboration” with org-mode Now ‘ess-request-a-process’ obeys ‘ess-gen-proc-buffer-name-function’, thanks to Ihor Radchenko. Changes and New Features in 19.04 (unreleased): • ESS[R]: When a background command is interrupted with C-g, ESS now asks the user if they want to disable background evaluations altogether. This is a resiliency measure against cases where background evals cause cascading errors or hangs. • ESS[R]: Background commands now propagate errors to Emacs. • ESS[R]: Background commands can now be disabled by process instad of globally. For instance when a process has failed to initialize properly, background evals are disabled for that particular process to avoid cascading errors. Other processes may still use background commands. • ESS[R]: ESSR commands are now more robust when ESSR is not in scope. This can happen when using ‘browser()’ in an environment that doesn’t inherit from the search path. • ESS[R]: Unexpected exits are now detected during startup. In that case an error is thrown with advice about how to recover. • ESS[R]: ‘options(width = )’ is now set on startup based on the width of the inferior window. • ESS[R]: Add support for R projects and start R by default in the project folder. • ESS[R]: Backticked symbols in the process buffer are no longer fontified as strings. • ESS[R]: ‘ess-command’ now runs R code in a sandboxed environment. Use ‘.ess.environment()’ to inspect the current environment. • ESS[R]: Added support for new syntax in R 4.0 and R 4.1. This concerns raw strings, lambda functions, and the pipe operator. • ESS[R]: Highlight error locations in rlang style backtraces • ESS[R]: Fixed issue that caused ESS-help to hang when usage blocks include R comments (#1025). Fix contributed by Bill Evans. • ESS: New ‘ess-elisp-trace-mode’ minor mode. Toggle it to start or stop tracing all ‘ess’-prefixed functions with ‘trace-function’. Tracing is useful for debugging background ESS behaviour. • ESS[R]: ‘ess-get-help-aliases-list’ now caches the aliases on the R side. This should speed up help lookup when the search path has changed and the aliases are read again. • ESS: ‘ess-command’ now uses a default timeout of 30 seconds. It should normally be avoided with long-running tasks because it causes Emacs to block while the command is running. If the timeout is reached, an error is thrown. An interrupt is also sent to the process in case of early exit. This is a behaviour change: you will now have to explicitly opt in blocking the whole Emacs UI for more than 30 seconds by supplying a larger timeout (use ‘most-positive-fixnum’ for infinity). • ESS: ‘ess-wait-for-process’ now returns nil if a timeout is reached. • ESS: ‘ess-get-words-from-vector’ gains a ‘timeout’ argument. • ESS[R]: Fixed performance issue with argument completions. The help summary for the argument is no longer displayed in the echo area. This fixes delays and hangs (#1062). • ESS[R]: ‘ess-command’ is now more robust and resilient to hangs and custom prompts (#1043). It also strips continuation prompts (‘+’ prompts) automatically and reliably (#1116). • ESS[R]: ‘ess-command’ now handles sinked consoles correctly. • ESS[R]: ‘ess-command’ no longer changes ‘.Last.value’. As a result, background tasks like completions no longer affect the last value binding (#1058). • ESS[R]: Namespaced evaluation is disable in roxygen examples (#1026). Part of this change is that namespaced evaluation has ... ...
