[ProjectFileManager::] Project File Manager.

|
|
Claiming and creating copies of the projectfile genre: used for Inform 7
|
|
source texts stored as stand-alone plain text files, outside the GUI apps.
|
|
|
|
@h Genre definition.
|
|
The |project_file_genre| can be summarised as follows. Copies consist of
|
|
single files. These are recognised by having the filename extension |.txt|,
|
|
|.ni| or |.i7|. They cannot be stored in nests. Their build graphs are
|
|
extensive, having "upstream" vertices representing possible ways to build or
|
|
release them, and having numerous "downstream" vertices as well: build edges
|
|
run out to the extensions, kits and language definitions that they need.
|
|
|
|
Note that |project_bundle_genre| and |project_file_genre| are managed
|
|
differently, but share the same annotation data structure |inform_project|.
|
|
However it is stored in the file system, a project is a project.

@ Project copies are annotated with a structure called an |inform_project|,
|
|
which stores data about extensions used by the Inform compiler.

@h Claiming.
|
|
Here |arg| is a textual form of a filename or pathname, such as may have been
|
|
supplied at the command line; |ext| is a substring of it, and is its extension
|
|
(e.g., |jpg| if |arg| is |Geraniums.jpg|), or is empty if there isn't one;
|
|
|directory_status| is true if we know for some reason that this is a directory
|
|
not a file, false if we know the reverse, and otherwise not applicable.
|
|
|
|
A project file needs to be a plain text file whose name ends in |.txt|, |.ni|
|
|
or |.i7|.

|
|
void ProjectFileManager::claim_as_copy(inbuild_genre *gen, inbuild_copy **C,
|
|
text_stream *arg, text_stream *ext, int directory_status) {
|
|
if (directory_status == TRUE) return;
|
|
if ((Str::eq_insensitive(ext, I"txt")) ||
|
|
(Str::eq_insensitive(ext, I"ni")) ||
|
|
(Str::eq_insensitive(ext, I"i7"))) {

@h Searching.
|
|
Here we look through a nest to find all projects matching the supplied
|
|
requirements; though in fact... projects are not nesting birds.
|
|
|
|
=
|
|
void ProjectFileManager::search_nest_for(inbuild_genre *gen, inbuild_nest *N,
|
|
inbuild_requirement *req, linked_list *search_results) {
|
|
}
|
|
|
|
@h Copying.
|
|
Now the task is to copy a project into place in a nest; or would be, if only
|
|
projects lived there.
|
|
|
|
=
|
|
void ProjectFileManager::copy_to_nest(inbuild_genre *gen, inbuild_copy *C, inbuild_nest *N,
|
|
int syncing, build_methodology *meth) {
|
|
Errors::with_text("projects (which is what '%S' is) cannot be copied to nests",
|
|
C->edition->work->title);
|
|
}
|
|
|
|
@h Build graph.
|
|
As with extensions, the graph for a project is made only on demand, because to make
|
|
it would mean fully parsing and partially syntax-analysing its source text.
|
|
|
|
=
|
|
void ProjectFileManager::building_soon(inbuild_genre *gen, inbuild_copy *C, build_vertex **V) {
|
|
inform_project *project = ProjectFileManager::from_copy(C);
|
|
Projects::construct_graph(project);
|
|
*V = project->chosen_build_target;
|
|
}
|
|
|
|
@h Source text.
|
|
|
|
=
|
|
void ProjectFileManager::read_source_text_for(inbuild_genre *G, inbuild_copy *C) {
|
|
Projects::read_source_text_for(ProjectFileManager::from_copy(C));
