0.8.0.0 (2022-08-19)

This releases brings a significant rewrite of Ema. If you choose to upgrade your apps from 0.6, see https://ema.srid.ca/start/upgrade for guidance.

GHC 9.x support
Better handling of URL anchors (#83; #87)
routeUrl uses UrlDirect by default. Use routeUrlWith if you want to change that.
Ema status indicator now works independently (requires no Tailwind)
Multisite rewrite (Ema has been mostly rewritten for better composability) (#82)
- Represent route encoding using Prism' from optics-core; add IsRoute class to define them.
  - Optional generic deriving of route prisms, so you do not have to hand-write them.
  - Automatic isomorphism checks ensures that encoding and decoding are isomorphic (route prisms are lawful)
- Composable Ema apps
  - There are two ways of composing Ema apps. Using heterogenous lists (see Ema.Route.Lib.Multi), or by defining a top-level route type (see Ex04_Multi.hs).
- Replace LVar with Dynamic.
  - Ema still uses LVar internally (for live server updates), but on the user-side one only needs to provide a Dynamic which is a tuple of initial value and an updating function. The unionmount library was changed to provide this tuple.
- Add EmaSite typeclass to "connect them all"
  - SiteArg: Type of value to pass from the environment.
  - siteInput: Define the Dynamic model for the site.
  - siteOutput: Asset (eg: HTML) to produce for each route.

0.6.0.0 -- 2022-02-05

Websocket API: Add ema.switchRoute to switch to other routes in live server.
Smaller core: remove helpers and examples (examples can be enabled by a flag)
- Helpers
  - Ema.Helpers.PathTree moved to separate package pathtree.
  - Ema.Helpers.FileSystem moved to separate package unionmount.
  - Ema.Helpers.Markdown moved to separate package commonmark-simple.
  - Ema.Helpers.Blaze is no more. See ema-template if you need a ready made template using blaze HTML and TailwindCSS.
- Examples with-examples cabal flag is made False by default. Examples are not exposed modules.
- Ema.Route.Slug moved to separate package url-slug

0.4.0.0 -- 2022-01-19

Pin TailwindCSS to 2.x, because the 3.x broke our CDN url
Remove unused Cabal deps (#61)
Tailwind.layoutWith: don't hardcode <body> attrs
Tailwind: module revamped and renamed to Tailwind.Helper.Blaze
runEma and friends:
- return the monadic's action's return value or generated files (dependent type)
CLI: add run subcommand that takes --host and --port (and remove environment hacks of $HOST and $PORT)

0.2.0.0 -- 2021-11-21

TODO(doc) runEma's action gets the CLI.Action as argument, to prevent the gen command from needing to monitoring files.
Live Server
- Avoid unncessary DOM patch on page load
- Handle invalid routes gracefully without breaking websocket
- Re-add <script> tags on hot reload
- Scroll to top on route switches
- Use secure websockets when on HTTPS
- Bind to loopback (127.0.0.1) for security reasons
- Do not handle target=_blank links in websocket route switch
Asset type
- Introduce the Asset type to distinguishing between static files and generated files. The later can be one of Html or Other, allowing the live server to handle them sensibly.
- Ema typeclass:
  - Drop staticAssets in favour of allRoutes (renamed from staticRoutes) returning all routes including both generated and static routes.
  - Drop Slug and use plain FilePath. Route encoder and decoder deal directly with the on-disk path of the generated (or static) files.
- Make the render function (which runEma takes) return a Asset LByteString instead of LByteString such that it can handle all routes, and handle static files as well as generation of non-HTML content (eg: RSS)
- Allow copying static files anywhere on the filesystem
routeUrl:
- Unicode normalize as well URI encode route URLs
- now returns relative URLs (ie. without the leading /)
  - Use the <base> tag to specify an explicit prefix for relative URLs in generated HTML. This way hosting on GitHub Pages without CNAME will continue to have functional links.
- Fix: prevent encoding of non-HTML paths
- Now takes the model type as argument, inasmuch as encodeRoute takes it as as well (to accomodate scenarios where route path can only be computed depending on model state; storing slug aliases for instance)
- Add routeUrlWith for non-pretty URLs
Ema.Slug
- Add Ord, Generic, Data and Aeson instances to Slug
- Unicode normalize slugs using NFC
- Add decodeSlug and encodeSlug
Add default implementation based on Enum for allRoutes
Warn, without failing, on missing static assets during static generation
Static generation
- Use block buffering to prevent logging from slowing down site generation
- Write .nojekyll
CLI
- Removed -C argument (orthogonal to Ema)
Helpers
- Helpers.FileSystem
  - Add Union mount support; re-exported from unionmount library
  - enrich FileAction type to distinguish between existance and new and update states
- Helpers.Tailwind
  - add overflow-y-scroll to body
  - Add twind shim before application's head
  - CDN: Use latest version always.
- Helpers.Markdown
  - add helpers to parse markdown; parseMarkdownWithFrontMatter and parseMarkdown
Examples
- ~~Remove Ex03_Documentation.hs (moved to separate repo, ema-docs)~~ Back to ./docs, but using Emanote.
- Add Ex03_Basic.hs example

0.1.0.0 -- 2021-04-26

First version. Released on an unsuspecting world.
