| 137 | <p>Groups should <em>not</em> generally contain negative USE flags, as this would |
195 | <p>Earlier drafts of this GLEP did not allow -use flags or <a class="reference" href="mailto:-@GROUPS">-@GROUPS</a>. However, |
| 138 | lead to confusion. Groups are intended to specify what will be enabled for |
196 | because of feedback along the lines of "we shouldn't disallow features |
| 139 | a given role, not what will be turned off. For example, if the @KDE group |
197 | just because some users won't understand them" (for example, <a class="footnote-reference" href="#id6" id="id2" name="id2">[3]</a>), these |
| 140 | disabled Gnome-related USE flags, and a user used <tt class="literal"><span class="pre">USE="@GNOME</span> <span class="pre">@KDE"</span></tt> to |
198 | are now allowed but discouraged.</p> |
| 141 | specify that they wanted both Gnome <em>and</em> KDE to be used where applicable, |
199 | <p>The problems are best illustrated by example. Say we have the following |
| 142 | chaos would ensue. However, for the sake of consistency, -flags should be |
200 | groups defined:</p> |
| 143 | supported even if their use is strongly discouraged.</p> |
201 | <pre class="literal-block"> |
| 144 | <p>It is proposed that <tt class="literal"><span class="pre">-@GROUP</span></tt> syntax should <em>not</em> be supported. Instead, |
202 | KDE X kde qt |
| 145 | users wishing to turn most things off could use the <tt class="literal"><span class="pre">-*</span></tt> USE syntax |
203 | GNOME X gtk gtk2 gnome |
| 146 | along with a group (for example, @RECOMMENDED) which turned on flags (for |
204 | </pre> |
| 147 | example, pam and readline) which should usually be used.</p> |
205 | <p>A user who wants a KDE desktop but no GNOME may do the following:</p> |
|
|
206 | <pre class="literal-block"> |
|
|
207 | USE="@KDE -@GNOME" |
|
|
208 | </pre> |
|
|
209 | <p>However, this will not give the desired effect -- the <tt class="literal"><span class="pre">X</span></tt> USE flag will |
|
|
210 | end up being disabled.</p> |
|
|
211 | <p>Similarly, -use flags could cause a lot of confusion if misused. If, for |
|
|
212 | example, the KDE group turned off GNOME things and the GNOME group turned |
|
|
213 | off KDE things:</p> |
|
|
214 | <pre class="literal-block"> |
|
|
215 | KDE X kde qt -gtk -gnome |
|
|
216 | GNOME X gtk gtk2 gnome -kde -qt |
|
|
217 | </pre> |
|
|
218 | <p>And a user wished to use both KDE and GNOME on a system, and so had USE |
|
|
219 | flags as follows:</p> |
|
|
220 | <pre class="literal-block"> |
|
|
221 | USE="@KDE @GNOME" |
|
|
222 | </pre> |
|
|
223 | <p>They would end up with:</p> |
|
|
224 | <pre class="literal-block"> |
|
|
225 | USE="X kde qt -gtk -gnome X gtk gtk2 gnome -kde -qt" |
|
|
226 | </pre> |
|
|
227 | <p>Which simplifies:</p> |
|
|
228 | <pre class="literal-block"> |
|
|
229 | USE="X gtk gtk2 gnome -kde -qt" |
|
|
230 | </pre> |
|
|
231 | <p>This is clearly not the desired effect.</p> |
