GNU Emacs and XEmacs have different philosophies regarding add-on packages. - -XEmacs has its own packaging system and maintains and distributes its own library of third party add-on modules. These are distributed in Fedora in the xemacs-packages-base and xemacs-packages-extra packages. GNU Emacs doesn't have any equivalent system, and third party add-ons are left for the user or distribution to install. - -The packaging naming guidelines state that: - -_Packages of emacs add-on components (code that adds additional functionality to emacs compatible editors) have their own naming scheme. It is often the case that a component will add functionality to several different compatible editors, such as GNU Emacs and XEmacs (and possibly development versions of these editors). The package name should take into account the upstream name of the emacs component._ - -_Where a component adds functionality to more than one emacs compatible editor, the package name should be of the form emacs-common-$NAME. In this case, the main package should contain only files common to all emacs compatible editors, and the code specific to each should be placed in a subpackage reflecting the specific editor $EDITOR-$NAME e.g., xemacs-$NAME, emacs-$NAME (the latter being the package specific to GNU Emacs). An example of this scheme can be found in the package emacs-common-muse._ - -_Where a component is designed to add functionality to only a single emacs compatible editor, the main package name should reflect this by being called $EDITOR-$NAME. An example of this situation can be found in the package emacs-auctex, which is built only for GNU Emacs._ - -Wherever possible, we encourage making an add-on package available for both GNU Emacs and XEmacs. One common case where that is not desirable is when an add-on package is already available for XEmacs in either xemacs-packages-base or xemacs-packages-extra. For example VM (a mail reader for Emacs) is provided for XEmacs in the xemacs-packages-extra package, but is not included in the emacs or emacs-common packages. Therefore it is sensible to create a package called emacs-vm which is the VM package for GNU Emacs only. Another such example is AUCTeX. - === Location of installed files -==== GNU Emacs - -For GNU Emacs, files for add-on package foo should be placed in %\{_emacs_sitelispdir}/foo which evaluates to /usr/share/emacs/site-lisp/foo. +Files for add-on package foo should be placed in %\{_emacs_sitelispdir}/foo which evaluates to /usr/share/emacs/site-lisp/foo.

The resulting compiled elisp files will then be included in the relevant emacs-foo and xemacs-foo packages. It is important to also include the source elisp files for several reasons. For example when debugging a problem with an (X)Emacs package, the Elisp debugger can look up the relevant code or symbol definition in the source lisp file if present. Also, it's sometimes helpful to jump to a variable description string from the Emacs help system. +Typically, an Emacs add-on package will be compiled from source elisp files. +The resulting compiled elisp files will then be included in the relevant emacs-foo package. +It is important to also include the source elisp files for several reasons. +For example when debugging a problem with an Emacs package, the Elisp debugger can look up the relevant code or symbol definition in the source lisp file if present. +Also, it's sometimes helpful to jump to a variable description string from the Emacs help system. -=== BuildArch for (X)Emacs add-on packages +=== BuildArch for Emacs add-on packages You should set BuildArch: noarch for add-on packages which only compile elisp files during building.

This is very uncommon. +If the package ONLY works with GTK support built into Emacs, then the package should have Requires: emacs. +This is very uncommon. ==== Why we need versioned Requires -Many elisp packages aim for backwards source level compatibility by checking whether some features exist in the (X)Emacs in use when the package is being run or byte-compiled. If yes, they use what's available. If no, they provide their own versions of missing functions, macros etc. This propagates into *.elc during byte compilation, and quite a few functions do get added between upstream (X)Emacs releases. - -So let's say I byte-compile a package into *.elc with XEmacs 21.5.28. Elisp package quux checks if the foo-bar function is available in the XEmacs being used to byte-compile it. Yes, it is, so the internal backwards compat version of foo-bar included in quux does not end up in the *.elc. Now, let's assume foo-bar was added in XEmacs 21.5.28 and didn't exist in 21.5.27 and we're trying to run the *.elc with 21.5.27 -> boom, foo-bar is not available. Note: this wouldn't happen if only *.el were shipped - *.elc are the potential and likely problem. Requiring >= version of the (X)Emacs used to byte-compile the *.elc is not the only solution (nor enough for all corner cases), but is the best one we currently have available. +Many elisp packages aim for backwards source level compatibility by checking whether some features exist in the Emacs in use when the package is being run or byte-compiled. +If yes, they use what's available. +If no, they provide their own versions of missing functions, macros etc. +This propagates into *.elc during byte compilation, and quite a few functions do get added between upstream Emacs releases. -The main package and subpackages will need to have appropriately version Requires to ensure that a recent enough version of (X)Emacs is installed.

The emacs-common and xemacs-common packages both place files in /etc/rpm which define macros containing the version of (X)Emacs installed. The relevant macros are: +==== Determining the Required Emacs version at package build time -.... -%{_emacs_version} -%{_xemacs_version} -.... +It is recommended to derive greater-than-or-equal-to valued versioned dependencies from the version of Emacs used to byte-compile the package at package build time. +The emacs-common package includes /usr/lib/rpm/macros.d/macros.emacs which defines a `+%\{_emacs_version}+` macro containing the version of Emacs installed. === Other packages containing Emacsen add-ons (Case II) -It is often the case that a software package, while not being primarily an Emacs add-on package, will contain components for (X)Emacs. For example, the Gnuplot program contains some elisp files for editing Gnuplot input files in GNU Emacs and running Gnuplot from GNU Emacs. In this case, we want to enable the (X)Emacs support IF (X)Emacs is installed, but we don't want to mandate the installation of (X)Emacs on installation of this package since (X)Emacs is not required for providing the core functionality of the package. To enable this, the emacs-filesystem and xemacs-filesystem sub-packages were created which own the /usr/share/emacs/site-lisp and /usr/share/xemacs/site-packages directories respectively. A package can then Require these (x)emacsfilesystem packages in order to install their Elisp files without pulling in (X)Emacs and their dependency chain. +It is often the case that a software package, while not being primarily an Emacs add-on package, will contain components for Emacs. +For example, the Gnuplot program contains some elisp files for editing Gnuplot input files in GNU Emacs and running Gnuplot from GNU Emacs. +In this case, we want to enable the Emacs support IF Emacs is installed, but we don't want to mandate the installation of Emacs on installation of this package since Emacs is not required for providing the core functionality of the package. +To enable this, the emacs-filesystem sub-package was created which owns the /usr/share/emacs/site-lisp directory. +A package can then Require the emacs-filesystem package in order to install its Elisp files without pulling in Emacs and its dependency chain. diff --git a/guidelines/modules/ROOT/pages/Naming.adoc b/guidelines/modules/ROOT/pages/Naming.adoc index 09cbfb7..2bd567e 100644 --- a/guidelines/modules/ROOT/pages/Naming.adoc +++ b/guidelines/modules/ROOT/pages/Naming.adoc @@ -265,40 +265,16 @@ SDL_ttf (TrueType font rendering support for SDL, relies on SDL) === emacs components Packages of emacs add-on components -(code that adds additional functionality to emacs compatible editors) -have their own naming scheme. -It is often the case that a component will add functionality -to several different compatible editors, -such as GNU Emacs and XEmacs -(and possibly development versions of these editors). -The package name SHOULD take into account the upstream name -of the emacs component. - -Where a component adds functionality to more than one emacs compatible editor, -the package name SHOULD be of the form `+emacs-common-$NAME+`. -In this case, -the main package SHOULD contain only files common -to all emacs compatible editors, -and the code specific to each SHOULD be placed -in a subpackage reflecting the specific editor `+$EDITOR-$NAME+` -e.g., `+xemacs-$NAME+`, `+emacs-$NAME+` -(the latter being the package specific to GNU Emacs). -An example of this scheme can be found in the package -`+emacs-common-muse+`. - -Where a component is designed to add functionality -to only a single emacs compatible editor, -the main package name SHOULD reflect this -by being called `+$EDITOR-$NAME+`. -An example of this situation can be found in the package -`+emacs-auctex+`, which is built only for GNU Emacs. +(code that adds additional functionality to emacs) +SHOULD have a name that takes into account the upstream name +of the emacs component by being called `+emacs-$NAME+`. *Examples:* .... -emacs-common-muse (muse component for all emacs compatible editors) -xemacs-muse (muse component subpackage that provides XEmacs specific files) -emacs-autex (autex component only for GNU Emacs) +emacs-auctex (auctex component for GNU Emacs) +emacs-deferred (deferred component for GNU Emacs) +emacs-flycheck (flycheck component for GNU Emacs) .... === Erlang modules
