FR-DEV-6 asks for three things — named presets, copy/paste between images, and batch-apply to a selection. The last two have been here for a while; this is the first. The format is the sidecar's, deliberately. A preset *is* the non-default half of a version, so the lines are the same lines keyed the same way, which makes the two files diffable against each other and lets someone debugging an edit paste a block from one into the other. One file rather than one per preset: a preset per file makes the name a path, and every name then has to survive a filesystem — a `/` becomes a directory, a name differing only in case collides on one platform and not another, and renaming becomes two operations that can half-fail. As a key in a document it is none of those. Unknown *parameters* needed no machinery. `Preset` already holds whatever keys it is given and resolves them against the descriptors only at apply time, so one written by a newer build survives by being stored. Only lines that are not `op.param = float` at all are preserved verbatim, which is the sidecar's version-skew promise made here too. Applying is the paste path with a different source, so a preset reaches a selection through the sidecar read-modify-write that was already there: no graph, no decode, no GPU, forty files or one. Two smaller decisions worth the record. A library that fails to parse is held empty in memory and *not* written back over — settings regenerate themselves and this is work, so a parse failure must not be the moment it is destroyed. And every save persists immediately and rolls the in-memory copy back if the write fails, so the sheet never lists a preset the file does not have. The grid's "Presets" button is gated on the selection alone, unlike the "Paste to 40" beside it. That button needs a clipboard armed this session; the preset list is whatever was saved last month, and hiding it behind an unrelated action is what makes a feature only its author knows about.

//! TRACES: FR-DEV-6
|
|
//! Copying develop settings from one photograph to others.
|
|
//!
|
|
//! # The three pieces
|
|
//!
|
|
//! * A [`Clipboard`] — one [`Preset`] held for the life of the window. Not
|
|
//! the system clipboard: these are typed values addressed by `op.param`,
|
|
//! and putting them on a text clipboard would mean anything that happened
|
|
//! to be copied afterwards silently disarmed the paste.
|
|
//! * An [`OpenImage`] — where the develop view's edit is *stored*, which is
|
|
//! what a copy is taken from and what a paste has to be written back to.
|
|
//! * The batch, in [`paste_to_selection`], which never opens an image at all.
|
|
//!
|
|
//! # Why a paste can reach images that are not open
|
|
//!
|
|
//! Applying settings to forty frames by opening forty develop sessions would
|
|
//! mean forty downloads of a whole RAW file and forty demosaics, to change
|
|
//! some numbers. The edit is *data* — [`Preset::amend`] operates on the
|
|
//! parameter map a sidecar already stores — so the batch is a read-modify-write
|
|
//! per file and never touches a GPU. That is what makes it usable on a phone.
|
|
//!
|
|
//! The cost is that a batch paste is only visible once the target is opened
|
|
//! and its sidecar read, which is the load path this module also provides.
|
|
//!
|
|
//! # Two stores, because there are two ways an image is opened
|
|
//!
|
|
//! An image from the library grid lives on the server and its sidecar goes
|
|
//! beside it, through the same writer a rating uses. An image named on the
|
|
//! command line is a local file with no library behind it, and its sidecar is
|
|
//! written beside it on disk. Both are the same document in the same format —
|
|
//! only the transport differs, which is why [`Stored`] is an enum over where
|
|
//! rather than two notions of what.
