Sweeprolog describes itself as: =================== Embedded SWI-Prolog =================== More at https://elpa.nongnu.org/nongnu/sweeprolog.html ## Summary: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SWEEP: SWI-PROLOG EMBEDDED IN EMACS Eshel Yaron m...@eshelyaron.com ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This manual describes the Emacs package Sweep (or `sweeprolog.el'), which provides an embedded SWI-Prolog runtime inside of Emacs. Table of Contents ───────────────── ## Recent NEWS: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SWEEP NEWS – HISTORY OF USER-VISIBLE CHANGES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This file contains the release notes for `sweep', an embedding of SWI-Prolog in Emacs. For further details, please consult the manual: [https://eshelyaron.com/sweep.html]. [https://eshelyaron.com/sweep.html] <https://eshelyaron.com/sweep.html> Version 0.12.0 on 2023-01-16 ════════════════════════════ Add on-hover descriptions to tokens in Prolog code ────────────────────────────────────────────────── `sweeprolog-mode' can now annotate tokens in Prolog code with textual descriptions that are displayed at the mouse tooltip when you hover over different tokens in the buffer. This is done by using the `help-echo' text property. You can also display these descriptions in the echo area with `C-h .' (`display-local-help'). New user option `sweeprolog-enable-help-echo' ───────────────────────────────────────────── This is a flag controlling whether `sweeprolog-mode' adds descriptions to tokens in Prolog code via the `help-echo' text property. It is set to `t' by default. Version 0.11.3 on 2023-01-15 ════════════════════════════ Improve integration with the standard `compilation-mode' ──────────────────────────────────────────────────────── In previous versions, following an error/warning message from a buffer that enables `compilation-mode' or one of its derivatives to a `sweeprolog-mode' buffer would forcefully set the `next-error-last-buffer' to the target `sweeprolog-mode' buffer. That would cause further `M-x next-error' (`M-g n') invocations to jump to the next Flymake error in that buffer, instead of going to the next error from the original `compilation-mode' buffer. This issue is fixed in this version. The manual is also extended to cover the usage of `compilation-shell-minor-mode' in Sweep Top-level buffers. New command `sweeprolog-top-level-send-goal' ──────────────────────────────────────────── This command can be called from anywhere to send a Prolog query to the Sweep Top-level and show the results. In `sweeprolog-mode' buffers, it’s bound to `C-c C-q'. It’s also bound to `q' in `sweeprolog-prefix-map', so if you’ve got that bound to e.g. `C-c p' you can run a query with this command from anywhere with `C-c p q'. Various documentation improvements ────────────────────────────────── The Sweep manual is extended with more details and useful information, and several docstrings have been tweaked. Version 0.11.2 on 2023-01-07 ════════════════════════════ Term Search now uses terms at point for “future history” ──────────────────────────────────────────────────────── When reading a search term in the minibuffer, `sweeprolog-term-search' now populates the “future history” with the terms at point starting from the most nested term. This means that you can type `M-n' in the minibuffer to quickly fill in the term at point in order to search for similar terms. Version 0.11.1 on 2023-01-06 ════════════════════════════ Term Search improvements ──────────────────────── Invoking `sweeprolog-term-search' with a prefix argument (i.e. typing `C-u C-c C-s') now prompts for an arbitrary Prolog goal that variables in the search term should satisfy. We also use a new function `sweeprolog-read-term' for reading the search term, which checks that the minibuffer contains a valid Prolog term before exiting. If the term is invalid this function refuses to exit the minibuffer and moves point to the position of the syntax error in the given term. Version 0.11.0 on 2023-01-05 ════════════════════════════ New command `sweeprolog-term-search' ──────────────────────────────────── _Experimental_ new command, bound to `C-c C-s' in `sweeprolog-mode' buffers, prompts for a Prolog term and searches for terms subsumed by it in the current buffer. All matching terms are temporarily highlighted and the cursor moves to the start of the next occurrence after point. Fix bug where `sweeprolog-forward-predicate' got confused by dynamic predicates ─────────────────────────────────────────────────────────────────────────────── In previous versions, typing `M-n' (`sweeprolog-forward-predicate') would sometimes go to the next dynamic predicate, jumping over regular predicates that come before it. Version 0.10.1 on 2023-01-01 ════════════════════════════ New user option `sweeprolog-read-predicate-documentation-function' ────────────────────────────────────────────────────────────────── This user option control how `C-c C-d' … …
