SiSU - Configuration,
2
Configuration of Environment
3
1. Configuration
4
1.1 Determining the Current Configuration
5
Information on the current configuration of SiSU should be
available with the help command:
6
sisu -v
7
which is an alias for:
8
sisu --help env
9
Either of these should be executed from within a directory that
contains sisu markup source documents.
10
1.2 Configuration files (config.yml)
11
SiSU configration parameters are adjusted in the configuration
file, which can be used to override the defaults set. This includes
such things as which directory interim processing should be done in and
where the generated output should be placed.
12
The SiSU configuration file is a yaml file, which means
indentation is significant.
13
SiSU resource configuration is determined by looking at the
following files if they exist:
14
./_sisu/sisurc.yml
15
~/.sisu/sisurc.yml
16
/etc/sisu/sisurc.yml
17
The search is in the order listed, and the first one found is used.
18
In the absence of instructions in any of these it falls back to the
internal program defaults.
19
Configuration determines the output and processing directories and the
database access details.
20
If SiSU is installed a sample sisurc.yml may be found in
/etc/sisu/sisurc.yml
21
Configuration of Documents
22
2. Skins
23
Skins modify the default appearance of document output on a document,
directory, or site wide basis. Skins are looked for in the following
locations:
24
./_sisu/skin
25
~/.sisu/skin
26
/etc/sisu/skin
27
Within the skin directory are the following the default
sub-directories for document skins:
28
./skin/doc
29
./skin/dir
30
./skin/site
31
A skin is placed in the appropriate directory and the file named
skin_[name].rb
32
The skin itself is a ruby file which modifies the default appearances
set in the program.
33
2.1 Document Skin
34
Documents take on a document skin, if the header of the document
specifies a skin to be used.
35
@skin: skin_united_nations
36
2.2 Directory Skin
37
A directory may be mapped on to a particular skin, so all documents
within that directory take on a particular appearance. If a skin exists
in the skin/dir with the same name as the document directory, it will
automatically be used for each of the documents in that directory,
(except where a document specifies the use of another skin, in the
skin/doc directory).
38
A personal habit is to place all skins within the doc directory, and
symbolic links as needed from the site, or dir directories as required.
39
2.3 Site Skin
40
A site skin, modifies the program default skin.
41
2.4 Sample Skins
42
With SiSU installed sample skins may be found in:
43
/etc/sisu/skin/doc and
/usr/share/doc/sisu/sisu_markup_samples/dfsg/_sisu/skin/doc
44
(or equivalent directory) and if sisu-markup-samples is installed also
under:
45
/usr/share/doc/sisu/sisu_markup_samples/non-free/_sisu/skin/doc
46
Samples of list.yml and promo.yml (which are used to create the right
column list) may be found in:
47
/usr/share/doc/sisu/sisu_markup_samples/dfsg/_sisu/skin/yml (or
equivalent directory)
48
3. Homepages
49
SiSU is about the ability to auto-generate documents. Home pages
are regarded as custom built items, and are not created by SiSU .
More accurately, SiSU has a default home page, which will not be
appropriate for use with other sites, and the means to provide your own
home page instead in one of two ways as part of a site's configuration,
these being:
50
1. through placing your home page and other custom built documents in
the subdirectory _sisu/home/ (this probably being the easier and more
convenient option)
51
2. through providing what you want as the home page in a skin,
52
Document sets are contained in directories, usually organised by site
or subject. Each directory can/should have its own homepage. See the
section on directory structure and organisation of content.
53
3.1 Home page and other custom built pages in a sub-directory
54
Custom built pages, including the home page index.html may be placed
within the configuration directory _sisu/home/ in any of the locations
that is searched for the configuration directory, namely ./_sisu;
~/_sisu; /etc/sisu From there they are copied to the root of the
output directory with the command:
55
sisu -CC
56
3.2 Home page within a skin
57
Skins are described in a separate section, but basically are a file
written in the programming language Ruby that may be provided to
change the defaults that are provided with sisu with respect to
individual documents, a directories contents or for a site.
58
If you wish to provide a homepage within a skin the skin should be in
the directory _sisu/skin/dir and have the name of the directory for
which it is to become the home page. Documents in the directory
commercial_law would have the homepage modified in skin_commercial
law.rb; or the directory poems in skin_poems.rb
