Download //TOP\ Emacs Source

When I browse Emacs help for functions via C-h f, I often want to peek into the Elisp/C implementation. I want to enter view-mode automatically when I access source code this way to avoid unnecessary modification. Is there a hook or function I can advise to accomplish this?

Update (after a night of sleep): This answer has a major flaw: it enables view-mode when navigating to any function, not just Emacs sources. This can be fixed, but you're better off using the answer by @phils.

By doing C-h f describe-function RET and then reading the source code of describe-function I discovered that it creates a "button" of a special type for links to function definitions: help-function-def.

This does not address your specific case, but the more general case of switching to view-mode whenever you visit a source file from a help buffer. I'm offering it as an alternative to @Constantine's answer, since it wasn't readable as a comment.

Richard Stallman began work on GNU Emacs in 1984 to produce a free software alternative to the proprietary Gosling Emacs. GNU Emacs was initially based on Gosling Emacs, but Stallman's replacement of its Mocklisp interpreter with a true Lisp interpreter required that nearly all of its code be rewritten. This became the first program released by the nascent GNU Project. GNU Emacs is written in C and provides Emacs Lisp, also implemented in C, as an extension language. Version 13, the first public release, was made on March 20, 1985. The first widely distributed version of GNU Emacs was version 15.34, released later in 1985. Early versions of GNU Emacs were numbered as 1.x.x, with the initial digit denoting the version of the C core. The 1 was dropped after version 1.12, as it was thought that the major number would never change, and thus the numbering skipped from 1 to 13.[30] In September 2014, it was announced on the GNU emacs-devel mailing list that GNU Emacs would adopt a rapid release strategy and version numbers would increment more quickly in the future.[31]

Lucid Emacs, based on an early alpha version of GNU Emacs 19, was developed beginning in 1991 by Jamie Zawinski and others at Lucid Inc. One of the best-known early forks in free software development occurred when the codebases of the two Emacs versions diverged and the separate development teams ceased efforts to merge them back into a single program.[39] Lucid Emacs has since been renamed XEmacs. Its development is currently inactive, with the most recent stable version 21.4.22 released in January 2009 (while a beta was released in 2013), while GNU Emacs has implemented many formerly XEmacs-only features.[40][better source needed]

Emacs is primarily a text editor and is designed for manipulating pieces of text, although it is capable of formatting and printing documents like a word processor by interfacing with external programs such as LaTeX, Ghostscript or a web browser. Emacs provides commands to manipulate and differentially display semantic units of text such as words, sentences, paragraphs and source code constructs such as functions. It also features keyboard macros for performing user-defined batches of editing commands.

Modes, in particular, are an important concept in Emacs, providing a mechanism to disaggregate Emacs' functionality into sets of behaviours and keybinds relevant to specific buffers' data. Major modes provide a general package of functions and commands relevant to a buffer's data and the way users might be interacting with it (e.g. editing source code in a specific language, editing hex, viewing the filesystem, interacting with git, etc.), and minor modes define subsidiary collections of functionality applicable across many major modes (such as auto-save-mode). Minor modes can be toggled on or off both locally to each buffer as well as globally across all buffers, while major modes can only be toggled per-buffer. Any other data relevant to a buffer but not bundled into a mode can be handled by simply focussing that buffer and live modifying the relevant data directly.

The Church of Emacs, formed by Richard Stallman, is a parody religion created for Emacs users.[50] While it refers to vi as the editor of the beast (vi-vi-vi being 6-6-6 in Roman numerals), it does not oppose the use of vi; rather, it calls it proprietary software anathema. ("Using a free version of vi is not a sin but a penance."[51]) The Church of Emacs has its own newsgroup, alt.religion.emacs,[52] that has posts purporting to support this parody religion. Supporters of vi have created an opposing Cult of vi.

I'm trying to use eshell inside emacs, so I don't have to switch between emacs and a terminal.When using bash, I have few bash scripts I usually source to export some env variables (in order to switch between different tool-versions and build-environments).Is it possible to somehow execute my scripts with bash, and put the exports (or some of them) in eshell.

When sourced from within eshell, it will start a bash, source the my-init.sh there (thus setting the MY_ENV variable), and then call env to obtain MY_ENV, and convert it with sed to something like (setenv "MY_VAR" "value") which is than sourced in the original eshell.

This seems to be a common misunderstanding for some reason, but "source" does not mean "set a few variables"; it means (in the context of sh) "execute the commands in this file in the current context". Therefore, the answer to the question "can I source a bash file in a program that uses some other incompatible language?" is no.

I downloaded Emacs source files, and installed it using make. After installing Emacs successfully, I manually removed the downloaded source files to save disk space. Now I want to remove Emacs and I tried to use sudo apt-get purge emacs. But it says Emacs has not been installed and will not be removed. But I can run Emacs by typing emacs in the terminal. Also the command which emacs shows the result /usr/local/bin/emacs.

and the issue in building emacs 24.5 seems to be that applying patches to openSUSE13.1 results in libpng16 instead of libpng12 and the src.rpm tries to link agains libpng12. Changing a couple of Makefiles to point to libpng16 instead results in a successful compile.

Source code here refers to any plain text collection of computerinstructions, possibly with comments, written using a human-readableprogramming language. Org can manage source code in an Org documentwhen the source code is identified with begin and end markers.Working with source code begins with identifying source code blocks.A source code block can be placed almost anywhere in an Org document;it is not restricted to the preamble or the end of the document.However, Org cannot manage a source code block if it is placed insidean Org comment or within a fixed width section.

On a graphical display, you can click mouse-1 in the fringe ofa source buffer, to set a breakpoint on that line (see Window Fringes).A red dot appears in the fringe, where you clicked. If a breakpointalready exists there, the click removes it. A C-mouse-1 clickenables or disables an existing breakpoint; a breakpoint that isdisabled, but not unset, is indicated by a gray dot.

A solid arrow in the left fringe of a source buffer indicates theline of the innermost frame where the debugged program has stopped. Ahollow arrow indicates the current execution line of a higher-levelframe. If you drag the arrow in the fringe with mouse-1, thatcauses execution to advance to the line where you release the button.Alternatively, you can click mouse-3 in the fringe to advance tothat line. You can click C-mouse-3 in the fringe to jump tothat line without executing the intermediate lines. This commandallows you to go backwards, which can be useful for running throughcode that has already executed, in order to examine its execution inmore detail.

By default, source file names and non-ASCII strings in the programbeing debugged are decoded using the default coding-system. If youprefer a different decoding, perhaps because the program beingdebugged uses a different character encoding, set the variablegdb-mi-decode-strings to the appropriate coding-system, or tonil to leave non-ASCII characters as undecoded octal escapes.

If using Emacs 28 with Spacemacs for the first time, all Spacemacs packages in your configuration will be downloaded and compiled. This may take 5-15 minutes and Emacs may make full use of your CPU (spawning several emacs processes on multi-core computers)

Expect to see lots of warning messages when installing more than 250 emacs packages. Ignore these warnings until all packages have been installed. If warnings still occur after restarting Emacs, then start investigating (or ask questions on #spacemacs channel in the Clojurians Slack community) ff782bc1db
