doctemplates v0.7 Release Notes

    • Add haddock Makefile target, which regenerates haddocks from README and tests the code example.

    • Remove BreakingSpace constructor on Template. Now we use doclayout BreakingSpace inside a Literal.

    • Add instance for ToContext a (Doc a).

    • Get benchmarks compiling again.

    • Use (doclayout) Doc internally and for rendered output.

      • TemplateTarget is now a type constraint synonym, not a regular typeclass.
      • Constraint on compileTemplate and applyTemplate simplified using TemplateTarget.
      • DocTemplates reexports Text.DocLayout.Doc.
      • The Literal costructor of Template now takes a Doc a rather than an a.
      • The SimpleVal constructor of Val now takes a Doc a rather than an a.
      • renderTemplate now returns a Doc a rather than an a. (This value can be converted to an a using render Nothing.)

    • Remove fromText from TemplateTarget. Now we use fromString from Data.String.

    • Parameterize Template on underlying stringlike type.

    • Improved behavior of partials.

    • Improve indent functions: don't drop final newline.

    • Allow blank lines in nested section.

    • Indent for Text/String: don't indent empty lines.

    • Additional tests and documentation about nesting.

    • Render items in for loop before separator. Otherwise we throw off column calculation.

    • Remove +-reflow; replace with toggle $~$.

    • Remove pNewline parser; it isn't needed now.

    • Remove +-nest.

    • Fix nest parsing bug.

    • Improve nesting.

      • Change Nested constructor for Template so it doesn't take a parameter.
      • Nesting level is now determined dynamically at render time rather than at compile time. This gives much better results when nesting occurs after template directives. Benchmarks show a slight penalty in performance (from 3.5ms to 3.1ms in rendering), but it's not too much.

    • Add filters. Filters transform the value of a variable, e.g. changing a map into an array of key/value pairs. Closes #5.

      • Internal: Add Filter type and [Filter] parameter on Variable.
      • Remove unVariable; now we have varParts and varFilters.
      • Document filters in README.md.
      • Implement filters.
      • Add tests.

    • Add ToYAML, FromYAML instances for Context, Val.
