* Xrefs and data links: use resolve_absolute for stored paths * CI: check that git dependencies come from storytold * CI: release only with git dependencies from storytold * Parse Cargo.lock as TOML when checking git sources * Use the shared git-sources check in CI * Parse cargo config, legacy .cargo/config included, in the git-sources check

//! Paths stored in a drawing: xref paths and table data links.
|
|
//!
|
|
//! Such a path reaches the file system only through [`resolve`]: a relative path is taken from
|
|
//! the drawing's folder, and only files on this computer, or on the network share the drawing
|
|
//! itself is on, are opened (see `craft_docpath`). A refused path is handled like a missing file,
|
|
//! with the reason in its status. Paths the user gives a command (XATTACH, -XREF Path, DATALINK)
|
|
//! are their own choice and are used as given.
