fix(file): name the |type: in FILE picker default labels

[chhoumann]

Two {{FILE:...|type:...}} pickers on the same folder and mode got the same default label, so a one-page form showed File from Attachments (link) twice. The same text also went into each picker's accessible name, so screen readers couldn't tell them apart either. The default label now names the type as written: File from Attachments (image, link) and File from Attachments (pdf, link). An explicit |label: still wins.

To do this, ParsedFileToken keeps the normalized |type: values (types), and the extension set is now derived from them. |type: hasn't been released yet (#1789), so there is no compatibility concern. Tokens without |type: keep their current labels.

Reproduce with a template containing:

image: {{FILE:Attachments|type:image|link}}
pdf: {{FILE:Attachments|type:pdf|link}}

and one-page input enabled.

Before	After

Tests:

• New E2E spec tests/e2e/file-type-label.test.ts. It runs the template in real Obsidian, checks both labels, picks each file through its picker (found by accessible name), and checks the written note. It fails on master with both labels as (link) and passes on this branch.
• Unit test covering the labels, including |type:image,.PDF normalization.
• Full unit suite (5800), full E2E suite (206), tsc, and lint all pass locally.

Note

Include |type: qualifiers in FILE picker default labels

FILE requirements without an explicit label now include their normalized type filters and non-name link mode in the generated label, so same-folder pickers with different type filters get distinct labels. Explicit labels still win.

• fileSyntax.ts adds ParsedFileToken.types plus parseFileTypes and getFileTypeExtensions helpers; parseFileToken now accumulates deduplicated, lowercased type names (leading dot stripped) and derives the extension filter from them, with any meaning unrestricted.
• RequirementCollector.ts builds default labels from these qualifiers instead of mode only.
• Adds unit tests in RequirementCollector.file.test.ts and an E2E scenario in file-type-label.test.ts covering same-folder image and PDF pickers.
• Behavioral Change: name-mode FILE tokens with types now also get a type-qualified label; dotted, case-insensitive types like .PDF render as pdf.

Summary by CodeRabbit

• Bug Fixes
  • File picker labels now include normalized file-type qualifiers, making pickers for different file types easier to distinguish—even when they use the same folder. For example, image and PDF pickers display their respective types. Explicitly configured labels remain unchanged, and selecting files from multiple pickers continues to work as expected.

📝 Walkthrough

Walkthrough

FILE token parsing now retains normalized type qualifiers separately from derived extensions. Automatic requirement labels include those qualifiers and non-default modes. Unit and end-to-end tests cover distinct labels for same-folder image and PDF pickers and linked output.

Changes

FILE Type Labels

Layer / File(s)	Summary
Normalize FILE type values src/utils/fileSyntax.ts	ParsedFileToken now exposes normalized types separately from derived extensions. The parser normalizes type values and derives extensions after processing the options.
Generate and verify FILE labels src/preflight/RequirementCollector.ts, src/preflight/RequirementCollector.file.test.ts, tests/e2e/file-type-label.test.ts	Automatic labels include type qualifiers and non-default modes, while explicit labels retain precedence. Unit and end-to-end tests cover label distinctions, picker selection, and linked output.
