1. Ensure Xcode command line tools or a Swift 5.9+ toolchain is installed.
2. Clone this repository.
3. Build the CLI:

   swift build

   Add -c release for a release optimized build.

Open tim without arguments to start with an empty buffer:

tim

Open a file, optionally jumping to a specific line:

tim path/to/file
tim path/to/file:+42
tim +42 path/to/file

Open a file over http(s):

tim https://web.site/document.html

Open a text-friendly Wikipedia article: Option: -w or --wikipedia

tim -w albert einstein

Open an RSS or Atom feed: Option: -r or --rss

tim -r https://example.com/feed.xml

Open a Bluesky user's public feed: Option -b or --bluesky

tim -b mierau.bsky.social

Additional flags:

• tim --help prints the available options.
• tim --version shows the current release tag.
• tim - reads buffer contents from standard input (ASCII or UTF-8 text only).
• tim -r <url> downloads and formats an RSS/Atom feed.
• tim -w <article title> fetches a text-friendly version of a Wikipedia article.
• tim -b <handle> fetches a Bluesky profile feed by handle, DID, or profile URL.
• Use -- before a path that begins with - to treat it literally.

Find within the current buffer with ⌃F, advance matches with ⌃G, move backward with ⌃R, and press Esc (or ⌃F a second time) to close. After opening the prompt, pressing ⌃F moves focus to the document so subsequent typing edits the buffer; run ⌃F once more to exit. Surround the query with / characters to run a regular expression, e.g. /^[A-Z].*/.
