| 7 Blog commands are high level tools to handle an XMPP blog. | |
| 8 They are using the generic pubsub arguments | |
| 9 | |
| 10 set | |
| 11 === | |
| 12 | |
| 13 publish a blog item. | |
| 14 | |
| 15 :ref:`pubsub_common` commands are used to specify the destination item. | |
| 16 | |
| 17 ``stdin`` is used to get the body of the blog post. | |
| 18 | |
| 19 examples | |
| 20 -------- | |
| 21 | |
| 22 Create a blog post with a body, a subject, 2 tags, and with comments allowed:: | |
| 23 | |
| 24 $ echo "This is post body" | jp blog set -T "This is a test message" -t test -t jp -C | |
| 25 | |
| 26 Create a blog post with rich content using `markdown` syntax, and no subject:: | |
| 27 | |
| 28 $ echo "This is a **rich** body" | jp blog set -S markdown | |

| 2946 | 64 edit |
| 65 ==== | |
| 66 | |
| 67 With edit command you can create a new blog post or modify an existing one using your | |
| 68 local editor (the one set in ``$EDITOR``). You'll edit 2 things: the body of the post, and | |
| 69 the metadata which contain things like title, comments infos, or tags. | |
| 70 | |
| 71 For some common editors (like **vim** or **Emacs**), the editor will be automatially | |
| 72 opened using a split screen with *body* in one side, and metadata on the other. If the | |
| 73 editor is not supported or doesn't support split screen, you'll edit first the *body*, then | |
| 74 the *metadata*. You can also specify editor and arguments in ``sat.conf``, see | |
| 75 `configuration <edit_conf_>`_ below | |
| 76 | |
| 77 If you don't change anything or publish an empty blog post, the edition will be cancelled. | |

83 edition with the ``-D, --current`` option like this:: |
| 2946 | 84 |
| 85 $ jp blog edit -D | |
| 86 | |
| 87 Note that item location must be re-specified if it has been used to create the draft, so | |
| 88 you'll have to reproduce the arguments to specify service, node or item (or the URL), | |
| 89 other data like tags will be restored from draft file of metadata. | |
| 90 | |
| 91 You can specify the syntax by using ``-S SYNTAX, --syntax SYNTAX``. If not specified, the | |
| 92 syntax set in your parameters will be used. | |
| 93 | |
| 94 When you edit a blog post, it is often useful to activate the ``-P, --preview`` option, | |
| 95 this will launch a web browser and refresh the page each time you save a modification in | |
| 96 your editor. By default, the browser registered as default in your system will be used, | |
| 97 and a new tab will be opened on each modification. This is not ideal, and we recommand to | |
| 98 set you configuration to activate automatic refreshing of the page instead, see `preview | |
| 99 configuration <edit_preview_>`_ below to see how to do. | |

| 130 .. _edit_metadata: | |
| 131 | |
| 132 metadata | |
| 133 -------- | |
| 134 | |
| 135 Metadata is set using a JSON object. The key you can use are: | |
| 136 | |
| 137 publish | |
| 138 boolean indicating if item can be published. Set to ``false`` if you want to work on a | |
| 139 draft and to avoid accidental publication. | |
| 140 | |
| 141 atom_id | |
| 142 atom entry identifier. This should not be modified manually. | |

| 146 | |
| 147 language | |
| 148 language of the content | |
| 149 | |
| 150 comments | |
| 151 array of URIs to the comments node, if any. | |

| 155 | |
| 156 author | |
| 157 human readable name of the entry author | |
| 158 | |
| 159 author_jid | |
| 160 jid of the author. This should notbe modified manually. | |
| 161 | |
| 162 author_jid_verified | |
| 163 true if the pubsub service confirmed that author_jid is the one of the publisher. It is | |
| 164 useless to modify this variable. | |
| 165 | |
| 166 title | |
| 167 the title of the message | |
| 168 | |
| 169 title_rich | |
| 170 the rich title of the message, in current text syntax. It will be automatically | |
| 171 converted to xhtml. | |
| 172 | |
| 173 .. _edit_conf: | |
| 174 | |
| 175 configuration | |
| 176 ------------- | |
| 177 | |
| 178 editor | |
| 179 ^^^^^^ | |
| 180 | |
| 181 Local editor used is by default the one set in ``$EDITOR`` environment variable, but you | |
| 182 can specify one in ``sat.conf``. To do so, you have to set the name of an editor | |
| 183 executable in the ``editor`` option in ``[jp]`` section. | |
| 184 | |
| 185 You can specify the args to use by using ``blog_editor_args`` option. Use | |
| 186 ``{content_file}`` to get the path of the main content file (the body of the blog post), | |
| 187 and ``{metadata_file}`` to get the path of the json metadata. | |
| 188 | |
| 189 .. sourcecode:: cfg | |
| 190 | |
| 191 [jp] | |
| 192 editor = kate | |
| 193 blog_editor_args = {content_file} {metadata_file} | |
| 194 | |
| 195 .. _edit_preview: | |
| 196 | |
| 197 preview | |
| 198 ^^^^^^^ | |
| 199 | |
| 200 To set the preview, you can use the options ``blog_preview_open_cmd`` and | |
| 201 ``blog_preview_update_cmd`` in your ``[jp]`` section. the former is the command to use to | |
| 202 open your browser when edition starts, and the later is the command to use when a | |
| 203 modification is saved. In both cases you may use ``{url}`` to set the location of local HTML file. | |
| 204 | |

205 This can be used to activate automatic refreshing of the page. |
| 2946 | 206 |
| 207 For **Konqueror**, you can use its D-Bus API to do refreshing. Ensure that ``qdbus`` is | |
| 208 installed on your system, and enter the following lines in your ``sat.conf``: | |
| 209 | |
| 210 .. sourcecode:: cfg | |
| 211 | |
| 212 [jp] | |
| 213 blog_preview_open_cmd = konqueror {url} | |
| 214 blog_preview_update_cmd = /bin/sh -c "qdbus $(qdbus org.kde.konqueror\*) /konqueror/MainWindow_1 reload" | |
| 215 | |
| 216 For **Firefox**, you may use ``xdotool`` on X11. Once you have installed this tool, enter the | |
| 217 following lines in your ``sat.conf``: | |
| 218 | |
| 219 .. sourcecode:: cfg | |
| 220 | |
| 221 [jp] | |
| 222 blog_preview_open_cmd = firefox -new-tab {url} | |
| 223 blog_preview_update_cmd = /bin/sh -c "WID=$(xdotool search --name 'Mozilla Firefox' | head -1); xdotool windowactivate $WID; xdotool key F5" | |
| 224 | |
| 225 This *xdotool* technique can be adapted to other browsers. | |
| 226 | |
| 227 syntax extensions | |
| 228 ^^^^^^^^^^^^^^^^^^ | |
| 229 | |
| 230 A dictionary with a mapping from syntax name to file extension can be used. This can be | |
| 231 useful to activate the right syntax highlighting in your editor. There is a default | |
| 232 mapping which can be overriden. | |
| 233 | |
| 234 The mapping is set in the ``syntax_ext_dict`` option of the ``[jp]`` section of your | |
| 235 ``sat.conf`` file. For instance, if your prefer do your ``.markdown`` for temp files | |
| 236 instead of the default ``.md``, you can use this: | |
| 237 | |
| 238 .. sourcecode:: cfg | |
| 239 | |
| 240 [jp] | |
| 241 syntax_ext_dict = {"markdown": "markdown"} | |
| 242 | |

250 detected. Configuration is the same as for `edit preview <edit_preview_>`_. This can be |
| 2946 | 251 used if you have already started an edition with ``jp blog edit`` but forgot to use the ``-P, --preview`` arguments. |
| 252 | |
| 253 example: | |
| 254 -------- | |
| 255 | |
| 256 Preview the draft at ``~/local/sat/blog/some_name/blog_something.md``:: | |
| 257 | |

| 2946 | 262 import |
| 263 ====== | |
| 264 | |
| 265 With this command you can import an external blog in a XMPP blog at the specified pubsub | |
| 266 location. | |
| 267 | |
| 268 The import is done using an *importer* name and a *location* which depends of the importer | |
| 2996 | 269 (it can be a path to a file, an URL to a blog, or something else). Let empty to get list |
| 270 of importers, and specify only importer name to get its description. | |
| 2946 | 271 |
| 272 By default, found images are re-uploaded to XMPP server, if you want to keep original | |
| 273 URLs, use the ``--no-images-upload`` option. | |
| 274 | |
| 275 Alternatively, you can re-upload images except for a specific host with ``--upload-ignore-host UPLOAD_IGNORE_HOST``. The images for the specified host will keep there original URLs while other will be uploaded to XMPP server. | |
| 276 | |
| 277 You shoud specify original blog host using ``--host HOST`` argument, this is used notably | |
| 278 to reconstruct relative URLs of media. | |
| 279 | |
| 280 Importers may have specific options, you can set them using the ``-o NAME VALUE, --option NAME VALUE`` argument. Check the importer description for details. | |
| 281 | |
| 282 examples: | |
| 283 --------- | |
| 284 | |
| 285 List available importers:: | |
| 286 | |
| 287 $ jp blog import | |
| 288 | |
| 289 Get description of ``dotclear`` importer:: | |
| 290 | |
| 291 $ jp blog import dotclear | |
| 292 | |
| 293 Import a Dotclear blog:: | |
| 294 | |
| 295 $ jp blog import dotclear /path/to/dotclear.dump | |
| 296 | |
| 297 Import a Dotclear blog without uploading images:: | |
| 298 | |
| 299 $ jp blog import --no-images-upload dotclear /path/to/dotclear.dump |
