The Big View
|
|
|
|
The whole dependency tree is supposed (in ideal world) to look somewhat like
|
|
the following. Please note that this deals only with the core parts of ELinks,
|
|
not extensions like bookmarks, cookies, globhist, mime etc. Those act like
|
|
modules and are generally self-contained - the main visible difference is that
|
|
they don't have their UI stuff in dialogs/foo.c but in foo/dialogs.c.
|
|
|
|
Note also that it isn't all that clean-cut as it looks. Some parts of e.g.
|
|
lowlevel/ or osdep/ are omnipresent as well and it's meant to be so (at least
|
|
for now). Also some other exceptions are possible; the exception to this is
|
|
util/, where no exceptions are permitted - it must have no dependencies to the
|
|
rest of the code whatsoever, not even compile-time ones. The other way around,
|
|
the gettext part of intl/ is generally omnipresent but the charset part is
|
|
pretty isolated - it could be probably drawn as connected to document and
|
|
terminal (actually, it is used when encoding forms in viewer too, but that
|
|
stuff should be probably moved to document).
|
|
|
|
viewer/ contains code concerning that big rectangle between bars at the top
|
|
and bars at the bottom, documents usually being shown inside. Logically, it
|
|
is in fact kind of a BFU widget, but in practice it has little in common with
|
|
the bfu/ widgets, it is special in many ways and deeply woven to the fabric
|
|
of session/ (e.g. session history is basically a chain of viewer widget
|
|
descriptors).
|
|
|
|
dialogs/ is special too. It in fact means to say "global and unique BFU
|
|
instances belonging to the ELinks core"/ but that's a rather long and boring
|
|
name, besides the nightmares associated with maintaining files and directories
|
|
containing spaces in GIT. The "global and unique BFU instances" part can be
|
|
represented by exmode, menus and leds (were they there). The "ELinks core"
|
|
part can be represented by options, document and downloads. The reason those
|
|
aren't in their respective directories (while bookmarks or formhist have their
|
|
dialogs.c) is that it's important to keep the dependencies sorted out
|
|
reasonably. Had there been e.g. terminal/dialogs.c, it would mean libterminal
|
|
has to depend on libbfu.a and so. (There are two 'managerial' exceptions
|
|
to this; don't dig into them, please. ;-)
|
|
|
|
scripting/ (== browser scripting) is also expected to hook all around, perhaps
|
|
it should be better in the omnipresent box.
|
|
|
|
The edges are directed and represent the "using" relation. Therefore,
|
|
"bfu -> terminal" means "bfu/ is using terminal/ services (but not
|
|
the other way around)".
