Tri

Kind of like an interactive tree --fromfile command

An interactive tree-based search tool with file preview. Give it some path-looking things, and it'll make them readable

go install github.com/sftsrv/tri@latest

Usage

# files in a directory
find ./ | tri

# use alternate preview
find ./ | tri --preview glow

# files in a pr
git diff --name-only | tri

Using Patterns

Use Regexps to parse the input string to create more complex commands

Escaping of regex special chars will depend on your shell

# viewing a formatted git log and showing the changes for each hash
git log --pretty=format:"%h %f"
| tri --preview "git show $1" --pattern "^(\w+)"

# using a more complex regexp and command
git log --pretty=format:"%h %f"
| tri --preview "echo title: $title hash: $hash" --pattern "(?<hash>\w+) (?<title>.*)"

Using Regexps

The structure of the regexp provided should be compatible with Go's implementation, with the following affordances made:

1. Named capture groups can be specified as <name> instead of ?P<name>
2. Regexps are always matched against a single line - so multiline captures are not meaningful

Using Patterns

References in pattern are indicated with a $ in the pattern

    - `$` refers to the entire match
    - `$0` (entire match), `$1` (first capture group), etc. refer to capture groups in order of capture
    - `$name` refers to named capture groups

Features / Ideas / TODOs

There are a lot of smaller improvements still left, but I've been using it for some time now and seems to work fine for me - but if you're keen to pick something up then do feel free to

• Search
• Preview with syntax highlighting (using bat if available)
• Custom preview command
• File selection
• Expand/Collapse folders
• Flatten direct paths (using --flat flag)
• Print tree (using --print flag)
• Async/non-blocking previews
• Make splits adjustable via keybinding (resize width of file tree)
• Allow explicit placeholder for file name in output command (like how it works for)
  • Uses Regexp for pattern definition and dynamic commands
• Move user search input to separate thread
• Make flat mode reactive to searching
• Make it possible to toggle flat on and off
• Tests for different formats and structures
• Fix fuzzy searching
• Regex based search in editor and via flag?
• Multi file select?
• Use Viewport (https://github.com/charmbracelet/bubbles) with reflow (https://github.com/muesli/reflow) for improved wrapping? - better is being able to provide the size of the active terminal to the underlying process but I have no idea how to do that
