Supported commands

This is a list of commands which are currently supported:

Block based:

• for-range
• for
  • base structure
  • filter
  • sort & order
  • limit & offset
• for-prop (mostly a copy & paste from for)
• value
• element
• eval
• when/is

Props based

• for
  • base structure
  • filter
  • sort & order
  • limit & offset
• for-prop (mostly a copy & paste from for)
• value
• prop (dual of element)
• calc

Missing features

• Stack based language.
  • Stack based evaluations for eval element
  • and for filter prop on for like cycles.
  • BREAKING replace numbers in for-range with these kinds of expressions.
  • Evaluate their usage in when/is
• Introduce escaping via "%" of 7bit ascii of strings within path expressions (to avoid issues with [ ] later on)
• Introduce the hashing functions needed to perform RAND ordering in order-by.

Milestones

v0.3.0

• At least feature parity with what it was before moving it out of vs-fltk.
• Some degree of documentation.
• Add support for element.text() & element.name() in query.
• Replace the current split implementation with something requiring less allocations

v0.4.0

• Add support for props-based commands.
• Initial setup for the test-suite.
• Add actual support of dot comparison in strings (to be tested).
• Add random as a proper order-by supported value (I must be able to specify the seed when building the document too).
• man page generation via meson (not great, but I'll take it).
• Add a proper xml schema for this language (rng in place of xsd as they are more flexible for unordered files that I want to support)

v1.0.0

• Support for all commands, except filter in all for variants & eval. Syntax for it has not been determined yet.
• Functional CLI needed.
• Install scripts working (testing needed).
• Some minimal testing facility is highly desirable.
