ovecc read

One element's source instead of a whole file.

Usage: ovecc read <TARGET> [OPTIONS]

Opening a 2,000-line file to look at one 20-line function costs the reader — human or agent — the whole file. read resolves the element and prints only it.

Target forms

Form	Prints
symbolName	The symbol's exact body, line-numbered, with a file:start-end header
path/file.ts:42	The enclosing symbol at that line
path/file.ts:10-40	That range
path/file.ts	The file's symbol outline, to pick from

The file:line form is the one query, impact, and grep already emit, so their output pipes straight in.

Example

$ ovecc read attach_entry
crates/ovecc-graph/src/acdc.rs:338-358  function attach_entry
  338  fn attach_entry(graph: &mut DiGraph<(), ()>, entry: NodeIndex, nodes: &[NodeIndex]) {
  339      let sources: Vec<NodeIndex> = nodes
  340          .iter()
  341          .copied()
  342          .filter(|node| {
  343              graph
  344                  .neighbors_directed(*node, petgraph::Direction::Incoming)
  345                  .next()
  346                  .is_none()
  347          })
  348          .collect();
  349      let mut seen = vec![false; nodes.len() + 1];
  350      seen[entry.index()] = true;

Ambiguous names

Several definitions under one name list their anchors instead of guessing which one you meant. Pass the file:line anchor from the list to get the body.

Options

Option	Effect
--limit <n>	Maximum lines to print before truncating (default 200; 0 = no cap)

Plus the global options.
