Prior to this commit, the PreviousID method of ServerUpdate seemed to be
a big unknown. This commit clarified that unknown by declaring two
conditions: when PreviousID returns an empty and non-empty ID.
The above change allows ServerUpdate events to both modify existing
servers as well as inserting new ones.
This commit breaks package split's API to take in int64 types instead of
int. This is because CompletionEntry now uses int64 over int for
concreteness.
This commit clarifies text.Imager and text.Avatarer's bound behaviors.
Prior to this, the only behavior that those two interfaces have
regarding bounds is that only the starting bound matters, because images
must not substitute texts.
This commit clarifies that images are allowed complement other sections.
For example, a Mentioner can "have" an Imager by having the bounds
overlap.
These details are intentionally vaguely defined (it doesn't list any
interfaces beyond Mentioner), so implementations of either side can
implement these however they want, as long as the bounds overlap.
In the future, further clarification rules may be added if needed.
This commit regenerates all files to adhere to the arguably-official
convention of having a standardized comment format to allow
distinguishing between written and generated files.
Refer to https://golang.org/s/generatedcode for more information.
This commit restores the old API prior to the repository commits to make
the Actions method of the Actioner interface take in a message ID and
return a slice of strings.
This commit adds the Stringer method representation into the repository.
The Rich struct of package text now implements Stringer and returns the
Content in plain text.
Prior to the repository commits, Rich used to have String().
Prior to this commit, the code generator for package empty doesn't have
a defined order. This commit now sorts the packages before generation,
which gets rid of the main map's undefined order.
Prior to this commit, the Mentioned method in MessageCreate didn't
return anything. This is a regression. It now returns a boolean that
indicates mentioned.
This commit adds the Avatar method into the Author interface. It returns
the URL if one, or it can return an empty string if either the service
does not support avatars or the user doesn't have avatars.
Prior to this commit, interface Author embedded interface Namer. This
doesn't work, as it is discouraged to keep a working state inside the
implementation of Author, but Namer's embedded Iconer requires a state.
The commit changed Author to use a Name method instead, which is only a
getter. It will no longer satisfy interface Name.
This commit fixes IconContainer's SetIcon, which was SetImage prior to
this commit. Before the code generation commits, this container
originally had SetIcon.
This commit also adds back ImageContainer, which was a regression during
the code generation changes. It has the SetImage method.
This package adds back the Plain function from the old package text as
well as a new function called SolidColor that returns a new RGBA color
with the alpha bits maxed out.
These functions are there for convenience. They're also outside the
scope of the code generator and repository.
This commit adds empty structs that implement no-op asserter methods for
interfaces in package text. Those implementations have "Text" prefixed
to their names.
The added implementations stay in the same place as cchat's.
This commit regenerates package text to use asserters instead of
manually asserting structs. This is to both bring consistency to the
interfaces and prepare it for the incoming IPC additions.
This commit also changed the Colorer interface to require returning a
32-bit RGBA color. Before, backends could return 24-bit RGB OR 32-bit
RGBA, but there wasn't a good way to distinguish between the two. Now,
backends must set the alpha bits to 0xFF if it's 24-bit only.
This package adds the code generation for package empty, which provides
structs that has no-op asserter methods for ease of use.
The package demonstrates one of the many possible use cases of having a
repository ready for code generation.
This commit fixes some trivial errors in the repository package. The
changes are breaking.
This commit also replaced the old cchat and text Go source code files
with ones generated straight from the repository. To regenerate, run
go generate ./...
The code is generated using the Jennifer library. In the future, all
generated code (including package empty and the RPC library) will use
Jennifer.
This commit adds a new package repository containing every single cchat
types that the package provides. Its goal is to be the source of truth
for the cchat files to be generated from.
A huge advantage of this is having types in an easily representable
format. This means that other languages can easily parse the repository
and generate its own types that are similar to the original ones.
Having a repository also allows easier code generation. For example,
this commit will allow generating the "empty" package in the future,
which would contain empty implementations of cchat databases that would
return nil for asserter methods.
This commit refactors entirely the ways cchat interfaces extend others.
Prior to this commit, interfaces extend itself simply by implementing
methods. This change is crucial to allow structs to decide whether or
not an interface is extended during runtime.
The current change adds the "As" methods into interfaces. When said, for
example, "Messenger extends Server," we now have the Server interface
implementing the AsMessenger method instead of before where the struct
implementing Server also implemented Messenger's methods.
For future references, these method will be called asserter methods.
The biggest motivation for this change is that these asserter methods
can allow backends to decide whether or not certain features are
implemented during runtime. For example, not all servers may support
sending messages. The asserting method is also simpler than the actual
type assertions done before.
Another motivation is to prepare cchat for an API that can reasonably be
translated to something that can be transferred over the wire. Although
the API itself will likely not be transferred over actual networking,
there are lots of plans for IPC-ing the API. This could mean that
developers would be able to develop the backends and frontends in any
programming language.
A downside to this is that the API is more restricted in terms of
extending beyond interfaces defined in the package. The initial goal of
this was to allow certain frontends to check for additional interfaces
outside of cchat that certain services could implement. However, this
goal is mostly moot, as interfaces like these require prior extensive
knowledge from both the developers of the backend and frontend
libraries.
This commit introduces many breaking changes that will break all current
code, both in the frontend and backend.
This commit changes the previous interface names to shorter versions.
This is done because, with the addition of the parent interface being
embedded in every extension interfaces, it is pointless to have the
name indicate this relationship. Furthermore, shorter and concise names
are more idiomatic.
This commit also introduces the "Is" method that is in every extension
interfaces. The purpose of this method is to provide an alternative
mechanism to check if an interface is extended.
Prior to the "Is" method, the only way for a backend to indicate
channels that can either be sent a message or not is to use two
separate types. Now, backends could implement a single type and return a
true or false on the Is method.
This method has a major disadvantage: it makes type assertions longer
and more complex. Refer to the "assert extension interfaces" example for
an example.
Despite the above disadvantage, this change is needed by the RPC
implementation in the future. Thus, it is worth the trouble of checks
being more verbose.
This commit adds the ID type, which is a type alias to a string. This
change does not break any APIs and is done purely for documentation
purposes.
This commit also adds backlog interfaces to add support for services
capable of storing and showing chat history.
A subtle behavior change with the above change would be that
MessageContainer implementations are now required to add a mechanism to
invalidate old containers when needed. For example, the MessagePrepender
passed into MessagesBefore must be invalidated by the frontend when the
channel in view is changed. This prevents stray messages from old
channels coming in.
There are many ways to invalidate a container, but the easiest way would
be to attach an optionally atomic boolean into the store and completely
separate the store from the view (aka widget).
The interface MemberListDynamicSection was added to allow server
implementations to ignore the dynamic section methods if needed.
A new method LoadLess was also introduced into the new interfaces along
with the old LoadMore. This method basically unrolls the member list as
the user scroll back up.
This commit breaks the old member list API in order to change several
things. These changes are done to improve the overall usability and
flexibility of their interfaces.
This commit introduces the method LoadMore into the MemberListSection
interface. The method was added to allow sections to be lazy loaded
conditionally. This allows the server to lazy load the member list over
the network.
In the future, there might be further modifications to allow clients to
invalidate or mark sections as stale, which would allow the server to
free up the list.
This commit also changed the old Name method of MemberListSection to use
the unified Namer interface. It also moved from using section's contents
as identifiers to having a dedicated ID method using the unified
Identifier interface.
This commit adds 2 extra string fields into the authentication entry
struct. The objective is to allow backends to hint additional
information that the user might want to know while authenticating.
Frontends that cannot do placeholders can opt for another way to display
the information, such as adding it into the name, surrounded by
parentheses.
This commit adds member list support for servers capable of showing
messages. This includes both backend and frontend interfaces.
A UserStatus type was added with the appropriate constants for this purpose,
but it could be used in the future for other purposes.
All cchat documentation has been moved off of the README and into
GoDoc's documentation sections. This is done to free up the README for
other useful information about the project that doesn't have to do with
the code itself.
This commit adds the MentionerAvatar and MentionedImage interfaces. This
interface gives the mentioned object an avatar or image. An example of
this would be showing a user's avatar. This allows the frontend to do
simple layouting.
The new behavior for Mentioner states that the frontends should be able
to use the highlighted segment as the mentioned object's display name.
For example, if the mentioned segment highlights "@username", then the
frontend should display "@username" as the large text.
This change was done because using a message as an argument for
SetMentioned was too much. The client can manually check which messages
have Mentioned being true and highlight them.
As we no longer need a message forr SetMentioned, it is now merged into
SetUnread. As such, SetUnread now takes both an unread and a mentioned
boolean.
This commit is a breaking change. It changes the UnreadIndicate method
to require returning an additional stop callback similar to that in
Nickname.
The motivation for this change was that frontends need a way to announce
cancellation before it destroys its server containers. This may happen
when the backend wants to replace in the container a completely new
list. As such, old lists will be destroyed, and the frontend will call
UnreadIndicate again. Because of that, the old callbacks must be cleaned
up.
This commit adds message attachments. More specifically, the
MessageAttachment struct was added to represent a single attachment.
Interfaces are added as well, that is ServerMessageAttachmentSender and
SendableMessageAttachments.
For the most parts, the frontend will use SendableMessageAttachments,
which extends the usual SendableMessage.
This commit adds the Mentioner interface. The objective is to have a
clickable mention string similar to that in Discord, that when pressed
will popup a small box containing the given user info.
In the future, Mentioner may be expanded to add Avatar capabilities, but
for now, it can be added using text segments.
This commit also clarified that segments can implement multiple
interfaces. This is done to allow segments such as Mentioner to also be
colored using Colorer.
Frontend implementations should, instead of a type switch, use multiple
if statements separately. This may introduce a lot more boilerplate code.
This commit adds Avatarer into the list of supported text segments. This
should work very similarly to Imager, except that avatars should be
rounded by the frontend.
This commit should make the text image APIs consistent with the main
cchat package.
This commit undos these latest changes and replaced them with the new
ImageContainer API as well as Image boolean in CompletionEntry.
These changes, unlike the earlier commits, are not breaking changes.
They are only additions.
ImageContainer is added for future usages, which translates to the
previous commits' IconContainer. The current IconContainer translates to
the previous commits' RoundIconContainer.
