105 | magnus | 1 | How to build new template packages for Prayer Webmail |
2 | ================================================= |
||
3 | |||
4 | Prayer uses its own macro expansion language, which is documented in |
||
5 | TEMPLATES. The templates (filename extension .t) are first translated |
||
6 | into C code (actually no executable code, merely data structures), |
||
7 | which is then compiled to object form. Originally, the object files |
||
8 | had to be linked with the prayer executables, but as a Debian |
||
9 | extension they can be assembled in shared libraries and loaded |
||
10 | dynamically. |
||
11 | |||
12 | This package contains the programs and scripts needed to build |
||
13 | template libraries, as well as a makefile to facilitate the process. |
||
14 | |||
15 | |||
16 | template-set.make |
||
17 | ----------------- |
||
18 | |||
19 | /usr/share/prayer/template-set.make can be used directly (via make -f) |
||
20 | or included from an ordinary Makefile. |
||
21 | |||
22 | The variable NAME defines the name of the template set. By default |
||
23 | it's set to the name of the current directory. NAME must be set on the |
||
24 | command line or *before* including template-set.make. An alternative |
||
25 | is to follow chapter 3.8 in the GNU Make documentation and _delegate_ |
||
26 | certain or all targets to template-set.make: |
||
27 | |||
28 | %: force |
||
29 | @$(MAKE) -f /usr/share/prayer/template-set.make NAME=foobar |
||
30 | force: ; |
||
31 | |||
32 | The variables TEMPLATES and TEMPLATES_FRONTEND list the top-level |
||
33 | templates that Prayer is known to use, and which should be defined |
||
34 | lest the user be met with a page saying nothing but "Template not |
||
35 | found". Unless all those templates are defined, or you redefine the |
||
36 | variables, the build will fail, but you can set VPATH to a directory |
||
37 | containing an existing template set to take the missing templates from |
||
38 | there. Just be sure that there are no intermediate files lying around! |
||
39 | |||
40 | Templates can call other templates by means of the CALL macro. They |
||
41 | are scanned recursively to make sure that all referenced templates are |
||
42 | included in the respective library. |
||
43 | |||
44 | A complete template package should consist of two libraries: one for |
||
45 | the session daemon and one for the front-end. The latter contains the |
||
46 | templates for the login screen and certain messages when no session |
||
47 | exists or none can be found, and since the users can't choose the |
||
48 | front-end template set it can be considered pretty much optional. To |
||
49 | skip building the front-end library, set TEMPLATE_LIBS = $(SESSION_LIB) |
||
50 | (also on the command line or before including template-set.make). |
||
51 | |||
52 | |||
53 | Installing |
||
54 | ---------- |
||
55 | |||
56 | To help build separate architecture-independent and architecture- |
||
57 | specific packages (as well as to avoid conflicts with the "install" |
||
58 | target you may want to use yourself), template-set.make provides two |
||
59 | install targets, "install-sources" and "install-libs", which do the |
||
60 | right thing. The standard DESTDIR variable is supported (instead of |
||
61 | BROOT, which is used in Prayer's own makefiles). |
||
62 | |||
63 | |||
64 | Images and CSS files |
||
65 | -------------------- |
||
66 | |||
67 | This package contains no tools to organise static files. Those should |
||
68 | simply be installed in /usr/share/prayer/icons and |
||
69 | /usr/share/prayer/static. Note that Prayer doesn't support sub- |
||
70 | directories, so files should be named in a way that avoids conflicts. |
||
