+The idea behind <c>ROOT</c> is that one can build a system with
+<c>ROOT=/somewhere</c> and then chroot into it or tar up
+<c>/somewhere</c> as a system image. It is not designed to allow the
+user to run <c>/somewhere/usr/bin/foo</c>.
+</p>
+
+<p>
+Ebuilds may reference <c>ROOT</c> only during <c>pkg_*</c> phases. It
+can't be used correctly in <c>src_*</c> phases, since <c>ROOT</c> may
+be different when merging a binary package. For example, a binary
+package may be built with <c>ROOT=/</c> and then installed onto a
+system using <c>ROOT=/somewhere</c>.
+</p>
+
+<p>
+When building a package, <c>ROOT</c> should not be used to satisfy the
+required dependencies on libraries, headers files etc. Instead, the
+files on the build system should be specified using <c>/</c>.
+</p>
+
+<p>
+In a cross compiling environment, ebuilds must not call any of the
+binaries inside <c>ROOT</c> since they may not be executable on the
+build system.

+

ebuild-writing/variables: update wrt ROOT always ending in a trailing slash

Per PMS[0], ROOT must end in a trailing slash. Remove the trailing
slash characters ('/') that appear after ${ROOT} in the example and
add a note about it.

There is a future EAPI request to remove this trailing slash
(#465722). Suggest the use of '${EROOT%/}' for maximum compatibility.

ebuild-writing/variables: move the trailing slash issue to a separate section

The ROOT section talks about using ${ROOT%/}/ notation to accommodate
for the upcoming EAPI. The variables D, ED, and EROOT also end in a
trailing slash. Create a separate section to talk about this issue.

+<title>Use of constant-value variables in ebuilds</title>
+<body>
+
+<p>
+Variables have significant value in ebuilds, making it possible to avoid
+unnecessary repetitions and make maintenance easier.  However,
+references to constant-value variables should be used with care as their
+excessive use can harm readability and increase maintenance burden (e.g.
+when renaming a package). In particular, using variables whose values
+have no direct correlation with the expected string should be avoided.
+</p>
+
+<p>The examples of beneficial constant-value variable references are:</p>
+<ul>
+  <li>
+    using <c>${PV}</c> and the variables derived from it (<c>${P}</c>,
+    <c>${MY_P}</c>…) in <c>SRC_URI</c> and <c>S</c> to avoid having
+    to update those variables for every version bump (assuming that
+    <c>${PV}</c> is used to indicate the upstream version);
+  </li>
+
+  <li>
+    using <c>${PF}</c> in <c>--docdir</c> path — this is a canonical
+    Gentoo path that is always required to match <c>${PF}</c>.
+  </li>
+</ul>
+
+<p>The examples of bad constant-value variable references are:</p>
+<ul>
+  <li>
+    using <c>${PN}</c> in <c>HOMEPAGE</c>, <c>EGIT_REPO_URI</c>
+    or the domain of <c>SRC_URI</c> — it breaks URL parsing in editors
+    and terminals, and makes it hard to copy the link for external use
+    (e.g. while reviewing via gitweb),
+  </li>
+
+  <li>
+    using <c>${PN}</c> (or other unnecessary helper variables)
+    excessively in <c>src_install()</c> — it impairs readability for
+    little benefit and causes a lot of trouble when the package needs to
+    be renamed.

ebuild-writing/variables: weaken the warning against third-party mirrors.

The warning against using third-party mirrors used to say that "the
mere existence of a third-party mirror list is not a good enough
reason to use it." That goes against a few existing uses of the

revision changes the warning, leaving the decision up to the

ebuild-writing/variables: document the mirror:// pseudo-protocol.

The thirdpartymirrors file is covered by the PMS, but unless you know
where to look, it's not easy to figure out what "mirror://" does in
SRC_URI. This commit adds a mention of the file and protocol under the
"SRC_URI" heading on the "Variables" page.

ebuild-writing/variables: Stop encouraging empty USE_EXPAND hack

Remove the suggestion that 'no flags = all options'.  We certainly
aren't doing it these days, and the problem is better resolved with
defaulting USE_EXPAND and/or REQUIRED_USE these days.

ebuild-writing/variables: Indicate multiple ebuild usage in tpm

Make it clearer that thirdpartymirrors should be used when multiple
ebuilds use the same mirror set.  It makes little sense to use it
when you are listing multiple random download locations for a particular
file.

ebuild-writing/variables: Indicate that HOMEPAGE is multi-valued

Indicate that HOMEPAGE can accept multiple values.  Expand freshmeat
fallback suggestion into the broader idea that package trackers can
be linked in addition to main HOMEPAGE (which is a common practice
e.g. for Python packages).  Simplify No_homepage suggestion to always
use it when there's no homepage, rather than when transitioning from old
homepage.

ebuild-writing/variables: update the paragraph about trailing slashes

The information dates back to pre-EAPI7 era and incorrectly states
that ROOT etc. always end with a trailing slash, which is incorrect
with EAPI7. Update the text to reflect both EAPI7 and pre-EAPI7
practices and suggest the bash suffix removal for pre-EAPI7 ebuilds to
ease transition.

ebuild-writing/variables: fix the trailing slash in ROOT for EAPI7

Before EAPI7, ROOT was guaranteed to end with a trailing slash. EAPI7
reversed this. Add back trailing slashes to ROOT in the example.

ebuild-writing/variables: add a "User environment" section.

Gentoo has always tried to respect a user's CFLAGS environment
variable, ensuring that it is passed to the underlying build
system. Likewise, CC and LDFLAGS are well-respected these days.

Recently, we have added some other variables to this list, like NM,
RANLIB, LD, and AS. The meanings of most of these are enshrined in
toolchain-funcs.eclass, but in order to properly support them, we must
document their intended use so that user's can set them to the correct
value and developers can inject them into the right spot in the
upstream build system. One motivating example package is PARI, whose
build system interprets the LD environment variable in a different way
than GNU librool interprets it. If a user sets LD to something
appropriate for libtool, the PARI build will fail, and conversely;
that is, without help from the ebuild.

This commit adds a new section to the ebuild-writing/variables page
documenting the origin and intended use of these variables within
Gentoo. This should ensure that users and Gentoo developers agree on
their meanings, and will guide ebuild development when a problematic
upstream build system is encountered.

+The following variables may be set in the user's environment and should be

+alongside an example of a valid value. Upstream usage may diverge, but ebuilds

+</ul>
+
+<p>
+Many of these variables only have an effect if they are invoked directly.
+For example, your compiler driver is usually responsible for assembling object
+files rather than a direct call to <c>${AS}</c>. In that case, setting
+<c>ASFLAGS</c> will have no effect on the build process; instead, you would set
+something like <c>CFLAGS="-Wa,-alh,-L"</c> to tell the C compiler to pass those
+flags to the assembler. The <c>LDFLAGS</c> variable is the exception to this
+rule, as it is intended to be passed to the compiler driver rather than
+<c>${LD}</c>.

+While Portage may recognise several different <c>RESTRICT</c> tokens, it is

+<body>
+
+<p>
+The idea behind <c>ROOT</c> is that one can build a system with
+<c>ROOT=/somewhere</c> and then chroot into it or tar up
+<c>/somewhere</c> as a system image. It is not designed to allow the
+user to run <c>/somewhere/usr/bin/foo</c>.
+</p>
+
+<p>
+Ebuilds may reference <c>ROOT</c> only during <c>pkg_*</c> phases. It
+can't be used correctly in <c>src_*</c> phases, since <c>ROOT</c> may
+be different when merging a binary package. For example, a binary
+package may be built with <c>ROOT=/</c> and then installed onto a
+system using <c>ROOT=/somewhere</c>.
+</p>
+
+<p>
+When building a package, <c>ROOT</c> should not be used to satisfy the
+required dependencies on libraries, headers files etc. Instead, the
+files on the build system should be specified using <c>/</c>.
+</p>
+
+<p>
+In a cross compiling environment, ebuilds must not call any of the
+binaries inside <c>ROOT</c> since they may not be executable on the
+build system.
+</p>
+
+<p>
+Below is an example of an ebuild that uses <c>ROOT</c> in
+<c>pkg_postinst()</c> to conditionally print an error message if an
+old and obsolete configuration file still exists:
+</p>
+
+<codesample lang="ebuild">

 <p>
-The idea behind <c>ROOT</c> is that one can build a system with
-<c>ROOT=/somewhere</c> and then chroot into it or tar up
-<c>/somewhere</c> as a system image. It is not designed to allow the
-user to run <c>/somewhere/usr/bin/foo</c>.
+Note that the <c>IUSE</c> variable is cumulative, so there is no need to specify
+USE flags used only within inherited eclasses within the ebuild's IUSE.
 </p>
+<note>
+You need not assign the IUSE variable in your ebuild if it is empty.
+</note>
 
 <p>
-Ebuilds may reference <c>ROOT</c> only during <c>pkg_*</c> phases. It
-can't be used correctly in <c>src_*</c> phases, since <c>ROOT</c> may
-be different when merging a binary package. For example, a binary
-package may be built with <c>ROOT=/</c> and then installed onto a
-system using <c>ROOT=/somewhere</c>.
+Arch USE flags (<c>sparc</c>, <c>mips</c>, <c>x64-macos</c> and so on) should
+not be listed.

+<title>REQUIRED_USE</title>
+<body>
 <p>
-When building a package, <c>ROOT</c> should not be used to satisfy the
-required dependencies on libraries, headers files etc. Instead, the
-files on the build system should be specified using <c>/</c>.
+The <c>REQUIRED_USE</c> variable contains a list of assertions that must be
+met by the configuration of USE flags to be valid for this ebuild. In order
+to be matched, a USE flag in a terminal element must be enabled
+(or disabled if it has an exclamation mark prefix).
 </p>
 
 <p>
-In a cross compiling environment, ebuilds must not call any of the
-binaries inside <c>ROOT</c> since they may not be executable on the
-build system.
+Essentially, <c>REQUIRED_USE</c> is an analogue of <c>DEPEND</c> style syntax.
+For example, to state that some combination is forbidden, i.e. "if foo is set,
+bar must be unset":
 </p>
 
+<codesample lang="ebuild">
+REQUIRED_USE="foo? ( !bar )"
+</codesample>
 <p>
-Below is an example of an ebuild that uses <c>ROOT</c> in
-<c>pkg_postinst()</c> to conditionally print an error message if an
-old and obsolete configuration file still exists:
+To state "if foo is set, then at least one of bar, baz, and quux must be activated":
+</p>
+<codesample lang="ebuild">
+REQUIRED_USE="foo? ( || ( bar baz quux ) )"
+</codesample>
+<p>
+To state "exactly one of foo, bar, or baz must be set, but not several":
 </p>
+<codesample lang="ebuild">
+REQUIRED_USE="^^ ( foo bar baz )"
+</codesample>
+<p>
+Note that the last relationship is that of an Exclusive OR (XOR).
+While an XOR could be formed from usual DEPEND syntax,
+a specific ^^ operator has been added for this case.
