Source Structure¶

Statements and Source Order¶

Kedi preserves source order for declarations and executable statements. Imports publish their exported bindings at the position of the import, and later writes replace earlier bindings:

[label] = draft
> import: labels
[label] = final

= <label>

The final assignment wins. The same rule applies when a procedure, type, value, or import reuses a name. Prefer unique public names; relying on replacement is mainly useful for deliberate overrides.

Indentation and Lexical Blocks¶

Indentation opens procedure, profile, directive, test, eval, and Python-owned blocks. Tabs count as width four when indentation is compared, but spaces are recommended so editor rendering cannot alter perceived scope.

@greet(name: str) -> str:
  [prefix] = Hello
  = <prefix>, <name>

The body must be indented relative to @greet. A dedent ends the block.

Top-Level and Procedure Scope¶

Top-level values are visible to following statements and procedures compiled in that environment. Procedure parameters and local assignments live in the procedure frame. Inner scopes may shadow outer values without permanently changing the caller's frame.

Agent configuration has capture semantics in addition to normal lexical scope: top-level directives are captured by following procedure definitions, while directives inside a procedure affect following model calls in that procedure.

Blank Lines¶

Blank lines do not close a block. Dedentation determines block boundaries. Within a multiline >> template, continuation rows are part of one prompt only while they remain adjacent continuation syntax at the same Kedi indentation.

Line Comments¶

# starts a line comment outside Python blocks:

[limit: int] = `10`  # Runtime limit

Escape a literal hash in Kedi text as \#:

= Ticket \#<`42`>

Python blocks use Python's own comment rules because their contents are parsed as Python rather than Kedi.

Block Comments¶

Matching lines containing only ### open and close a block comment:

###
This workflow is intentionally deterministic after classification.
The block can span multiple lines.
###

The delimiters may be indented with their surrounding Kedi block. They must be paired, must occupy their own lines, and ### cannot appear inside the comment body as ordinary text.

Profile Docstrings¶

The first block comment inside a procedure or profile is documentation, not merely discarded text:

@slugify(value: str) -> str:
  ###
  Convert a display label into a stable lowercase slug.
  ###
  = `value.strip().lower().replace(" ", "-")`

Procedure docstrings feed Python introspection, editor hovers, virtual stubs, and tool descriptions when the procedure is exposed as an agent tool. A block comment after another body statement remains a normal comment.

Reserved Names¶

args is the default runtime-owned command-line argument binding and cannot be assigned or removed. Embedders can change the identifier through the compiler environment before compilation, but ordinary programs should treat it as reserved.

Directive names and output identifiers are also validated. Unknown > directives fail instead of being treated as prompt text.
