+ GNU LESSER GENERAL PUBLIC LICENSE
2
+ Version 3, 29 June 2007
3
+
4
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
5
+ Everyone is permitted to copy and distribute verbatim copies
6
+ of this license document, but changing it is not allowed.
7
+
8
+
9
+ This version of the GNU Lesser General Public License incorporates
10
+ the terms and conditions of version 3 of the GNU General Public
11
+ License, supplemented by the additional permissions listed below.
12
+
13
+ 0. Additional Definitions.
14
+
15
+ As used herein, "this License" refers to version 3 of the GNU Lesser
16
+ General Public License, and the "GNU GPL" refers to version 3 of the GNU
17
+ General Public License.
18
+
19
+ "The Library" refers to a covered work governed by this License,
20
+ other than an Application or a Combined Work as defined below.
21
+
22
+ An "Application" is any work that makes use of an interface provided
23
+ by the Library, but which is not otherwise based on the Library.
24
+ Defining a subclass of a class defined by the Library is deemed a mode
25
+ of using an interface provided by the Library.
26
+
27
+ A "Combined Work" is a work produced by combining or linking an
28
+ Application with the Library. The particular version of the Library
29
+ with which the Combined Work was made is also called the "Linked
30
+ Version".
31
+
32
+ The "Minimal Corresponding Source" for a Combined Work means the
33
+ Corresponding Source for the Combined Work, excluding any source code
34
+ for portions of the Combined Work that, considered in isolation, are
35
+ based on the Application, and not on the Linked Version.
36
+
37
+ The "Corresponding Application Code" for a Combined Work means the
38
+ object code and/or source code for the Application, including any data
39
+ and utility programs needed for reproducing the Combined Work from the
40
+ Application, but excluding the System Libraries of the Combined Work.
41
+
42
+ 1. Exception to Section 3 of the GNU GPL.
43
+
44
+ You may convey a covered work under sections 3 and 4 of this License
45
+ without being bound by section 3 of the GNU GPL.
46
+
47
+ 2. Conveying Modified Versions.
48
+
49
+ If you modify a copy of the Library, and, in your modifications, a
50
+ facility refers to a function or data to be supplied by an Application
51
+ that uses the facility (other than as an argument passed when the
52
+ facility is invoked), then you may convey a copy of the modified
53
+ version:
54
+
55
+ a) under this License, provided that you make a good faith effort to
56
+ ensure that, in the event an Application does not supply the
57
+ function or data, the facility still operates, and performs
58
+ whatever part of its purpose remains meaningful, or
59
+
60
+ b) under the GNU GPL, with none of the additional permissions of
61
+ this License applicable to that copy.
62
+
63
+ 3. Object Code Incorporating Material from Library Header Files.
64
+
65
+ The object code form of an Application may incorporate material from
66
+ a header file that is part of the Library. You may convey such object
67
+ code under terms of your choice, provided that, if the incorporated
68
+ material is not limited to numerical parameters, data structure
69
+ layouts and accessors, or small macros, inline functions and templates
70
+ (ten or fewer lines in length), you do both of the following:
71
+
72
+ a) Give prominent notice with each copy of the object code that the
73
+ Library is used in it and that the Library and its use are
74
+ covered by this License.
75
+
76
+ b) Accompany the object code with a copy of the GNU GPL and this license
77
+ document.
78
+
79
+ 4. Combined Works.
80
+
81
+ You may convey a Combined Work under terms of your choice that,
82
+ taken together, effectively do not restrict modification of the
83
+ portions of the Library contained in the Combined Work and reverse
84
+ engineering for debugging such modifications, if you also do each of
85
+ the following:
86
+
87
+ a) Give prominent notice with each copy of the Combined Work that
88
+ the Library is used in it and that the Library and its use are
89
+ covered by this License.
90
+
91
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
92
+ document.
93
+
94
+ c) For a Combined Work that displays copyright notices during
95
+ execution, include the copyright notice for the Library among
96
+ these notices, as well as a reference directing the user to the
97
+ copies of the GNU GPL and this license document.
98
+
99
+ d) Do one of the following:
100
+
101
+ 0) Convey the Minimal Corresponding Source under the terms of this
102
+ License, and the Corresponding Application Code in a form
103
+ suitable for, and under terms that permit, the user to
104
+ recombine or relink the Application with a modified version of
105
+ the Linked Version to produce a modified Combined Work, in the
106
+ manner specified by section 6 of the GNU GPL for conveying
107
+ Corresponding Source.
108
+
109
+ 1) Use a suitable shared library mechanism for linking with the
110
+ Library. A suitable mechanism is one that (a) uses at run time
111
+ a copy of the Library already present on the user's computer
112
+ system, and (b) will operate properly with a modified version
113
+ of the Library that is interface-compatible with the Linked
114
+ Version.
115
+
116
+ e) Provide Installation Information, but only if you would otherwise
117
+ be required to provide such information under section 6 of the
118
+ GNU GPL, and only to the extent that such information is
119
+ necessary to install and execute a modified version of the
120
+ Combined Work produced by recombining or relinking the
121
+ Application with a modified version of the Linked Version. (If
122
+ you use option 4d0, the Installation Information must accompany
123
+ the Minimal Corresponding Source and Corresponding Application
124
+ Code. If you use option 4d1, you must provide the Installation
125
+ Information in the manner specified by section 6 of the GNU GPL
126
+ for conveying Corresponding Source.)
127
+
128
+ 5. Combined Libraries.
129
+
130
+ You may place library facilities that are a work based on the
131
+ Library side by side in a single library together with other library
132
+ facilities that are not Applications and are not covered by this
133
+ License, and convey such a combined library under terms of your
134
+ choice, if you do both of the following:
135
+
136
+ a) Accompany the combined library with a copy of the same work based
137
+ on the Library, uncombined with any other library facilities,
138
+ conveyed under the terms of this License.
139
+
140
+ b) Give prominent notice with the combined library that part of it
141
+ is a work based on the Library, and explaining where to find the
142
+ accompanying uncombined form of the same work.
143
+
144
+ 6. Revised Versions of the GNU Lesser General Public License.
145
+
146
+ The Free Software Foundation may publish revised and/or new versions
147
+ of the GNU Lesser General Public License from time to time. Such new
148
+ versions will be similar in spirit to the present version, but may
149
+ differ in detail to address new problems or concerns.
150
+
151
+ Each version is given a distinguishing version number. If the
152
+ Library as you received it specifies that a certain numbered version
153
+ of the GNU Lesser General Public License "or any later version"
154
+ applies to it, you have the option of following the terms and
155
+ conditions either of that published version or of any later version
156
+ published by the Free Software Foundation. If the Library as you
157
+ received it does not specify a version number of the GNU Lesser
158
+ General Public License, you may choose any version of the GNU Lesser
159
+ General Public License ever published by the Free Software Foundation.
160
+
161
+ If the Library as you received it specifies that a proxy can decide
162
+ whether future versions of the GNU Lesser General Public License shall
163
+ apply, that proxy's public statement of acceptance of any version is
164
+ permanent authorization for you to choose that version for the
165
+ Library.

+ Several improvements over WP's default excerpt. The size of the excerpt can be limited using character or word count, and HTML markup is not removed.
10
+
11
+ == Description ==
12
+
13
+ This plugin adds several improvements to WordPress' default way of creating excerpts.
14
+
15
+ 1. It can keep HTML markup in the excerpt (and you get to choose which tags are included)
16
+ 2. It trims the excerpt to a given length using either character count or word count
17
+ 3. You can customise the excerpt length and the ellipsis character that will be used when trimming
18
+ 4. The excerpt length is *real* (everything belonging to HTML tags is not counted)
19
+ 5. Possibility to ignore custom excerpts and use the generated one instead
20
+ 6. Theme developers can use `the_advanced_excerpt()` for even more control (see the FAQ)
21
+
22
+ In addition to keeping HTML markup in the excerpt, the plugin also corrects HTML that might have been broken due to the trimming process.
23
+
24
+ Version 0.2.1 adds support for multibyte characters (eg. Chinese and Japanese). This is slightly experimental, more details in the FAQ.
25
+ Plugin translations are fully supported and language files are included for translation. The FAQ provides more info on this, also.
26
+
27
+ == Installation ==
28
+
29
+ After you've downloaded and extracted the files:
30
+
31
+ 1. Upload the complete `advanced-excerpt` folder to the `/wp-content/plugins/` directory
32
+ 2. Activate the plugin through the 'Plugins' menu in WordPress
33
+ 3. Go to 'Excerpt' under the 'Options' tab and configure the plugin
34
+
35
+
36
+ == Frequently Asked Questions ==
37
+
38
+ = Why do I need this plugin? =
39
+
40
+ The default excerpt created by WordPress removes all HTML. If your theme uses `the_excerpt()` to view excerpts, they might look weird because of this (e.g. smilies are removed, lists are flattened, etc.) This plugin fixes that and also gives you more control over excerpts.
41
+
42
+ = Does it work for WordPress version x.x.x? =
43
+
44
+ I haven't had the chance to test the plugin on many versions of WordPress. It has been tested on 2.2 through 2.7, but it might work on other versions, too. You can safely try it yourself, because the plugin is unlikely to break anything (it's only an output filter). Please let me know if you succesfully tested it on another version of WordPress.
45
+
46
+ = Is this plugin available in my language? / How do I translate this plugin? =
47
+
48
+ The plugin comes bundled with a few languages. The correct language will automatically be selected to match your [WordPress locale](http://codex.wordpress.org/WordPress_in_Your_Language).
49
+
50
+ More information on translation will be added in the future.
51
+
52
+ = Does this plugin support multibyte characters, such as Chinese? =
53
+
54
+ First of all, it should be noted that word-based excerpt length only works if your language uses normal whitespace as a word separator. If you use another language, you have to uncheck the *Use words?* option.
55
+
56
+ PHP's support for multibyte characters is not perfect. The plugin provides support for these characters to the best of its ability, but there are no guarantees that everything will work.
57
+ Your best bet is to use UTF-8 encoding (which WordPress uses by default). If you still encounter problems, check with your host if the *mbstring* PHP extension is enabled on your server.
58
+
59
+ = Can I manually call the filter in my WP templates, for example? =
60
+
61
+ The plugin automatically hooks on `the_excerpt()` function and uses the parameters specified in the options panel.
62
+
63
+ If you want to call the filter with different options, you can use `the_advanced_excerpt()` template tag provided by this plugin. This tag accepts [query-string-style parameters](http://codex.wordpress.org/Template_Tags/How_to_Pass_Tag_Parameters#Tags_with_query-string-style_parameters) (theme developers will be familiar with this notation).
64
+
65
+ The following parameters can be set:
66
+
67
+ * `length`, an integer that determines the length of the excerpt
68
+ * `use_words`, if set to `1`, the excerpt length will be in words; if set to `0`, characters will be used for the count
69
+ * `no_custom`, if set to `1`, an excerpt will be generated even if the post has a custom excerpt; if set to `0`, the custom excerpt will be used
70
+ * `ellipsis`, the string that will substitute the omitted part of the post; if you want to use HTML entities in the string, use `%26` instead of the `&` prefix to avoid breaking the query
71
+ * `exclude_tags`, a comma-separated list of HTML tags that must be removed from the excerpt
72
+ * `allow_tags`, a comma-separated list of HTML tags that are allowed in the excerpt
73
+
74
+ A custom, advanced excerpt call could look like this:
75
+
76
+ `the_advanced_excerpt('length=320&use_words=0&no_custom=1&ellipsis=%26hellip;&exclude_tags=img,p,strong');`
77
+
78
+ = Does this plugin work outside the Loop? =
79
+
80
+ No, this plugin fetches the post from The Loop and there is currently no way to pass a post ID or anything custom of that kind to it.
81
+ You can, however, consider to [start The Loop manually](http://codex.wordpress.org/The_Loop#Multiple_Loops).
