This package provides a minor mode for editing SOPS-encrypted files. To enable it automatically, set global-sops-mode. Users can decrypt with sops-edit-file, save changes with sops-save-file, or discard them with sops-cancel. The files are displayed in read-only mode to prevent accidental corruption, which is useful for partly encrypted files with only one encrypted line.

semantic-stickyfunc-mode shows the function point is currently in at the first line of the current buffer. This is useful when you have a very long function that spreads more than a screen, and you don't have to scroll up to read the function name and then scroll down to original position.

Org Ref is an Emacs library that provides rich support for citations, labels and cross-references in Org mode.

The basic idea of Org Ref is that it defines a convenient interface to insert citations from a reference database (e.g., from BibTeX files), and a set of functional Org links for citations, cross-references and labels that export properly to LaTeX, and that provide clickable functionality to the user. Org Ref interfaces with Helm BibTeX to facilitate citation entry, and it can also use RefTeX.

It also provides a fairly large number of utilities for finding bad citations, extracting BibTeX entries from citations in an Org file, and functions to create and modify BibTeX entries from a variety of sources, most notably from a DOI.

Org Ref is especially suitable for Org documents destined for LaTeX export and scientific publication. Org Ref is also useful for research documents and notes.

helm-make or helm-make-projectile will give you a helm selection of directory Makefile's targets. Selecting a target will call compile on it.

This package provides an ESS-like binding to send lines or regions to a REPL from Shell buffers.

Monroe is a nREPL client for Emacs, focused on simplicity and easy distribution, primarily targeting Clojure users

This package provides a dired-mode interface for fd's result.

Valign provides visual alignment for Org mode, Markdown and Table.el tables on GUI Emacs. It can properly align tables containing variable-pitch font, CJK characters and images. Meanwhile, the text-based alignment generated by Org mode (or Markdown mode) is left untouched.

mastodon.el is an Emacs client for Mastodon, the federated microblogging social network.

YASnippet is a template system for Emacs. It allows you to type an abbreviation and automatically expand it into function templates.

SRV implements RFC 2782 (SRV records). It is used to look up hostname and port for a service at a specific domain. There might be multiple results, and the caller is supposed to attempt to connect to each hostname+port in turn.

This package provides font lock and automatic escaping and unescaping of quotes.

VHDL-ts-mode provides syntax highlighting, indentation, imenu, which-func, navigation and basic beautify and completion features to navigate and edit VHDL files.

The main command of the tiny extension for Emacs is tiny-expand. It is meant to quickly generate linear ranges, e.g. 5, 6, 7, 8. Some elisp proficiency is an advantage, since you can transform your numeric range with an elisp expression.

This package enables automatic visibility toggling of org-mode elements depending on cursor position. Hidden fragment parts appear when the cursor enters a fragment and disappear when it leaves.

This package provides a major mode for viewing certificates, CRLs, and other PKI-related files. It uses OpenSSL for viewing PEM and DER encoded PKI entities.

This package integrates restclient-mode with Org.

This package define functions for swapping buffers between windows contained in the same frame. An alternate behavior is to have the current window switch to the previous buffer instead of swapping with the other window.

Puni is an Emacs minor mode for structured editing: soft deletion, expression navigating and manipulating. It supports many major modes out of the box.

This package provides the auto-dark-mode minor mode, which enables automatic switching between two user-defined (customizable) themes. This transition occurs seamlessly in response to dark mode being enabled or disabled in the desktop preferences (such as in GNOME). It uses DBus to query the system configured value. To enable it, put the following snippet to your Emacs configuration file:

(require auto-dark)
(auto-dark-mode t)

To customize the themes used, visit M-x customize-group auto-dark.

Helm Selector is a collection of Helm helper functions for convenient buffer selection.

It is especially helpful to create Helm sessions to navigate buffers of a given mode in a “do what I mean” fashion:

If current buffer is not of mode X, switch to last buffer of mode X. If current buffer is of mode X, show a Helm session of all buffers in mode X. In the Helm session, it’s also possible to input an arbitrary name which will be used for the creation of a new buffer of mode X.

This package allows reading Reddit from within Emacs interactively.

Mint mode provides syntax highlighting for Mint language.

pcre2el or rxt (RegeXp Translator or RegeXp Tools) is a utility for working with regular expressions in Emacs, based on a recursive-descent parser for regexp syntax. In addition to converting (a subset of) PCRE syntax into its Emacs equivalent, it can do the following:

• convert Emacs syntax to PCRE

• convert either syntax to rx, an S-expression based regexp syntax

• untangle complex regexps by showing the parse tree in rx form and highlighting the corresponding chunks of code

• show the complete list of strings (productions) matching a regexp, provided the list is finite

• provide live font-locking of regexp syntax (so far only for Elisp buffers – other modes on the TODO list).
