| 53 =head1 ABOUT | |
| 54 | |
| 55 Chronicle is a simple tool to convert a collection of text files, | |
| 33 | 56 located within a single directory, into a blog consisting of static |
| 57 HTML files. | |
| 1 | 58 |
| 59 It supports only the bare minimum of features which are required | |
| 60 to be useful: | |
| 61 | |
| 62 * Tagging support. | |
| 63 | |
| 64 * RSS support. | |
| 65 | |
| 66 * Archive support. | |
| 67 | |
| 68 The obvious deficiencies are: | |
| 69 | |
| 85 | 70 * Lack of support for instant commenting. |
| 1 | 71 |
| 72 * Lack of pingback/trackback support. | |
| 73 | |
| 74 Having said that it is a robust, stable, and useful system. | |
| 75 | |
| 76 =cut | |
| 77 | |
| 46 | 78 |
| 44 | 79 =head1 BLOG FORMAT |
| 80 | |
| 81 The format of the text files we process is critical to the output | |
| 82 pages. Each entry should look something like this: | |
| 83 | |
| 84 =for example begin | |
| 85 | |
| 86 Title: This is the title of the blog post | |
| 87 Date: 2nd March 2007 | |
| 88 Tags: one, two, three, long tag | |
| 89 | |
| 90 The text of your entry goes here. | |
| 91 | |
| 92 =for example end | |
| 93 | |
| 94 In this example we can see that the entry itself has been prefaced | |
| 60 | 95 with a small header. An entry header is contains three optional lines, |
| 96 if these are not present then there are sensible defaults as described | |
| 97 below: | |
| 98 | |
| 99 =over 8 | |
| 100 | |
| 101 =item Title: | |
| 102 Describes the title of the post. If not present the filename of the entry | |
| 103 is used instead. | |
| 104 | |
| 105 =item Date: | |
| 106 The date the post was written. If not present the creation time of the | |
| 107 file is used instead. | |
| 108 | |
| 109 =item Tags: | |
| 110 Any tags which should be associated with the entry, separated by commas. | |
| 111 | |
| 112 =back | |
| 44 | 113 |
| 114 The text of the entry itself is assumed to be HTML, however if you | |
| 115 have the optional modules installed you may write it in Markdown or | |
| 60 | 116 Textile formats - if they are not present you will receive a message |
| 117 informing you of the names of the required modules. | |
| 44 | 118 |
| 60 | 119 You may specify the format of your entries either in the configuration |
| 120 file, or via the command line flag B<--format>. | |
| 44 | 121 |
| 46 | 122 =cut |
| 123 | |
| 124 | |
| 125 =head1 CONFIGURATION | |
| 126 | |
| 127 The configuration of the software is minimal, and generally performed | |
| 128 via the command line arguments. However it is possible to save settings | |
| 60 | 129 either in the file global /etc/chroniclerc or the per-user ~/.chroniclerc |
| 46 | 130 file. |
| 131 | |
| 60 | 132 If you wish you may pass the name of another configuration file to |
| 133 the script with the B<--config> flag. This will be read after the | |
| 134 previous two files, and may override any settings which are present. | |
| 135 | |
| 136 The configuration file contains lines like these: | |
| 46 | 137 |
| 138 =for example begin | |
| 139 | |
| 140 input = /home/me/blog | |
| 141 | |
| 142 output = /var/www/blog | |
| 143 | |
| 144 format = markdown | |
| 145 | |
| 146 =for example end | |
| 147 | |
| 148 Keys which are unknown are ignored. | |
| 44 | 149 |
| 150 =cut | |
| 151 | |
| 152 | |
| 153 =head1 OPTIONAL CACHING | |
| 154 | |
| 60 | 155 To speed the rebuilding of a large blog the compiler may use a local |
| 156 Memcached deaemon, if installed and available. | |
| 44 | 157 |
| 158 To install this, under a Debian GNU/Linux system please run: | |
| 159 | |
| 160 =for example begin | |
| 161 | |
| 162 apt-get update | |
| 163 apt-get install memcached libcache-memcached-perl | |
| 164 | |
| 165 =for example end | |
| 166 | |
| 167 You may disable this caching behaviour with --no-cache, and see the | |
| 168 effect with --verbose. | |

| 85 | 182 =head1 OPTIONAL COMMENTING |
| 183 | |
| 184 Included with the chronicle code you should find the file | |
| 185 cgi-bin/comments.cgi. | |
| 186 | |
| 187 This file is designed to write submitted comments to the local | |
| 188 filesystem of your webserver. If you install that, and edit the | |
| 189 path at the start of teh script you should be able to include | |
| 190 comments in your blog. | |
| 191 | |
| 192 In short there are three things you need to do: | |
| 193 | |
| 194 =over 8 | |
| 195 | |
| 196 =item Install the CGI script and edit the path at the start. | |
| 197 | |
| 198 =item Copy the output comments to your local blog source. | |
| 199 | |
| 200 =item Run this script again with --comments=./path/to/comments | |
| 201 | |
| 202 =back | |
| 203 | |
| 143 | 204 This should include the comments in the static output. More |
| 205 explicit instructions are provided within the file 'COMMENTS' | |
| 206 included within the distribution. | |
