Quickly jump between related source files in your project.

This Visual Studio Code extension finds files related to the currently active editor file using user-configurable matchers and opens the next file in the sorted list (including the current file). It is useful for jumping between header/source pairs, generated artifacts, or other related file sets and is completely configurable.

• With a file open and the editor focused, press F4 to open the next related file.
• Or run the command from the Command Palette: Related Sources: Next Related File.

• Find related files based on configurable regular-expression matchers.
• Includes the current file in the candidate list, sorts the list alphabetically, and opens the next file (wraps to the first).
• Keyboard shortcut: F4 (when the editor has focus).
• Works with named capture groups and numbered capture groups when substituting into target paths.
• Default matchers setup for chromium source projects.

The extension uses the relatedsources.matchers setting (an array) to discover related files. Each matcher is an object with the following properties:

• sourceRegexp (string) — a regular expression to match the current file's path (relative to the workspace root). Named capture groups ((?<name>...)) or numbered capture groups can be used.
• targetPath (string) — a glob-style target pattern. Use ${name} to substitute named capture groups or ${1} for numbered groups. The pattern is interpreted relative to the workspace root.
• name (string) — a friendly name for the matcher.

Example settings (to add to your workspace or user settings):

"relatedsources.matchers": [
  {
    "sourceRegexp": "^(?<path>.*)\\.[^.]*$",
    "targetPath": "${path}.*",
    "name": "Same filename"
  },
  {
    "sourceRegexp": "^(?<path>.*)\\.[^.]*$",
    "targetPath": "out/*/gen/${path}.*",
    "name": "Generated files"
  },
  {
    "sourceRegexp": "^out/*/gen/(?<path>.*)\\.[^.]*$",
    "targetPath": "${path}.*",
    "name": "Generated files (reverse)"
  }
]

The example above:

• ^(?<path>.*)\\.[^.]*$ matches a filename and captures the path (without extension) into the path group.
• ${path}.* finds files that share the same base filename (different extensions, folders, etc.).
