In 022045ae05 a regression was introduced: if no *slideshowAPI*
is specified in the branding file, Calamares refuses to start, with
a YAML failure.
Before the refactoring, we had `YAML::Node doc` and looked up
the *slideshowAPI* in it with `doc["slideshowAPI"]`. After the
refactoring, we had `const YAML::Node& doc`. The `const` makes
all the difference:
- subscripting a non-existent key in a mutable Node silently
returns a Null node (and possibly inserts the key);
- subscripting a non-existent key in a const Node returns an
invalid or undefined node.
Calling IsNull() or IsScalar() on a Null node works: the functions
return a bool. Calling them on an invalid node throws an exception.
So in the **const** case, this code can throws an exception that it
doesn't in the non-const case:
`doc[ "slideshowAPI" ].IsScalar()`
- Massage the code to check for validity before checking for scalar
- Add a `get()` that produces more useful exception types when
looking up an invalid key
- Use `get()` to lookup the slideshow node just once.
- Add access to the panel-sides membe of the view manager, and
calculate which sides are populated by panels (if any).
- Pass the calculated panel-sides to the view manager before it
starts adding viewpages, so they get consistent margins.
- All the headers go to relevant subdirs, but we don't keep
libcalamares and libcalamaresui apart.
- While here, remove unused variable from libcalamares CMake
- link the library privately -- the public API uses QVariantMap
- install FindYAMLCPP just in case
- add yamlcpp explicitly in the few places that really need it
(e.g. netinstall testing the parsing of netinstall.yaml)
- Add the Calamares CMake-modules to the search path automatically
- Export to CalamaresTargets.cmake and use namespace Calamares::
- Document imported targets
- Find Qt, because the translations machinery will need macros from that
- The installed lib links to IMPORTED libraries from KF5, so we need
to find them (again) as well.
- When loading QML V2, both loadQmlV2Complete() and changeSlideShowState()
lock the same mutex, introduced in e7f4479df1.
- Explicitly unlock when loading is done and we need to change the state
immediately.
- For testing purposes, it's useful to load a module externally
and then register it to the ModuleManager (this hands off ownership).
- Refactor overall module loading to use the exposed single-module method.
- QML files need to be searched in specific places; this was initialized
by Calamares, but not for the text application. Move initialization
into the library.
- Previously, unless setDefaultFontSize() was called explicitly,
the default size would be 0, leading to unexpected and weird
displays (and a warning on stderr).
- If setDefaultFontSize() is not called, get a sensible size instead
(like defaultFontHeight() was already trying to do).
- It is the requirements model (checking) that reports progress, and now
the model is accessible (ask for it with requirementsModel(), make the
messages come from there.
- The architecture of letting someone build up a list of requirements
from data emitted by the ModuleManager is broken: if it gets loaded
later, it will miss data; passing around complicated objects is
no fun anyway. Get rid of it, on the way to "ModuleManager has
its own model of requirements".
- Give the ModuleManager a RequirementsModel -- that is the source
of truth about the module-requirements of the modules managed
by that particular ModuleManager.
- Let the RequirementsChecker operate on a given RequirementsModel.
Doesn't compile (but I need to get it off this machine)
- Prepare to implement a picture-based slideshow alongside QML
- Split QML loading into the slideshow component
This might be good prep-work for moving QML loading out of the QMLViewStep as well.
- This code has existed for a long time but never stored anything
to the Branding object, and the most literal slideshow (just some
images) was not implemented.
- This is a good example of being overly clever in C++
- the whole API with an enum requesting a specific string is a bit weird,
although it makes sense from the 'might need more strings specified'
point of view.
- rename enlarge to ensureSize() and change the meaning from
"make this much bigger" to "make sure this is displayed",
which is easier on the caller to calculate.
- Add some extra checks for validity of m_currentStep (an index)
- Start off with explicitly invalid index, and keep it so until
loading is complete; this prevents the situation where quit-at-end
gets triggered after loading the very first module.
- Introduce an enum for panel-side
- Expose this to QML -- I can imagine that QML panels need to know
which side of the Calamares window they're on.
- Refactor loading the setting into a method that handles both
flavor and side
- With an empty list, the question is meaningless
- .. and we called this with an empty list while constructing the
ViewManager; if quit-at-end is true, then this would terminate
Calamares immediately because the list was at the end.
- Now the back button should be done by clients as well
- Refactor in CalamaresWindow to avoid leaking local button pointers
to surrounding code.
- Add macro UPDATE_BUTTON_PROPERTY for convenience in ViewManager
(ugh, macro) to change a value and emit corresponding update signal.
- add properties for the next button (enabled, label, icon...)
- update those properties as normal
- connect to the properties in the UI implementation
- the checker only collects and calls requirements; it has no
UI component, and only manages data (and a thread to do the
checking). Move it out of the UI library.
- this function lives in Module -- and is the only thing typing
Module to the ViewSteps and JobTypes. Split it out into its
own funciton. Nothing else in Module needs to befriend the
ViewSteps, so we move the friend declaration around a bit
as well.
- while here, apply coding style.
This is prep-work for moving module to libcalamares.
- drop the current and completed roles, and expose only
the currentIndex. QML can use the QObject property on
the model, while QWidgets can call internally through
the model's data() function.
- we don't need to provide role names for this, so drop that bit.
- simplify the delegate code while here.
- In some cases, it makes sense to close Calamares automatically
when it is done. Set *quit-at-end* to do so -- although this
probably also means you should remove the *finished* page.
Pull in the instance-weight changes and type-improvements,
but not the part where special-casing of unsquash is dropped:
weights are still per-job, not per-module.
- Refactor into a support method and two API points
- Use std::transform for doing-things-to-a-list
- Add searchQmlFile that only takes a name, for
non-modules to use.
- Registration of QML modules may need to be done
for more parts of Calamares. Move into the library,
out of the model.
- Register for QML when using the QML sidebar.
- This is utility code, so it can be in the QML "service"
from Calamares, rather than in the QmlViewStep itself.
That makes it usable for other QML bits as well.
- The name is just the module identifier, and now we
search for *m@i* and also *m* from that identifier,
the name becomes much less important -- and it
can be set from the config key *qmlFilename* as well.
