Issues

• Fix: If same light color is given then fastn makes only one class

-- ftd.text: Hello
background.solid: $bg-yg

-- ftd.text: hello
background.solid: yellow


-- ftd.color bg-yg:
light: yellow
dark: green

Both ftd.text invocation will have same background color and both background will change on dark mode to green

• Link in container type component not working correctly
• condition over the outermost element in the component definition

-- component bar:
boolean flag:

-- ftd.column:
if: { flag }

...

-- end: ftd.column

-- end: bar

• export/exposing not working for module

For the module rithik.ftd

-- import: bar
export: ritesh
exposing: ritesh

-- doc.home:
category: rithik

-- component home:
module category: <some default value>

-- home.category.ritesh:

component home does not find ritesh

Post Release:

• global variables in fscript

  -- string name: fastn
  -- string join():
  
  name + "is a language".
  

• fastn.app
• Code syntax highlighting (prism)
  • Remove theme and class when value is null in setStaticProperty
• Fix local argument reference order
• If device is mobile then discard content
• JS Code documentation
• marked warning in console
• js based runtime
  • testing against all existing 0.3 code base
  • $processor$ using function calls
• fastn performance issue
  • fastn build optimisation
• fastn 0.4 versioning

Good to have:

• Variable interpolation
• Markup
• fastn serve --log
• ftd.grid
• ftd.scene
• Besides text color, ftd.text can have gradient and image
• Web component: Besides on_change, let's add on_insert, on_delete for mutablelist
• Creating html file for image in fastn build (was supported on fastn 0.2)
• Better error messages

Issues:

• Horizontal Rule of markdown is not working

Example:

-- ds.markdown:

To create a Horizontal Rule we write

***

• Highlight not working in code-block

• Add closure to uis to display 0th item

  Example one:

  -- ftd.ui list uis:
  -- ftd.text: Hello World
  -- end: ftd.ui
  
  -- uis.0:
  

  Example two:

  -- ftd.ui list uis:
  -- ftd.text: Hello World
  -- end: ftd.ui
  
  -- foo:
  ui: $ui.0
  
  -- component foo:
  ;; The type should be `optional ftd.ui ui:` Since `$ui.0` should be optional reference.
  ftd.ui ui:
  
  ;; If 0th item is replaced or set or delete, the effect should be displayed here.
  -- foo.ui:
  
  -- end:
  

• if condition doesn't work for ftd.ui element
  Example:

  -- ftd.ui list uis:
  -- ftd.text: Hello World
  -- end: ftd.ui
  
  -- uis.0:
  ;; This doesn't work
  if: { uis.0 != NULL}
  

The key goal of this release is performance. We are planning this release to be completely backward compatible with 0.3 code base.

As part of our js based runtime, we will also get dynamic-dom working.
