pike-fmt

Standalone Pike source code formatter using tree-sitter-pike. Normalizes indentation, whitespace, and optionally operator spacing.

Installation

bun install

Build

bun run build

Usage

Format a file and print to stdout:

bun run src/cli.ts < file.pike

Format multiple files in-place (recursive):

bun run src/cli.ts -w .

CLI Flags

| Flag | Description | |------|-------------| | --check | Exit non-zero if any file needs formatting | | --diff | Show unified diff of changes | | --list | List files that would be changed | | -w, --write | Write formatted output in-place | | --operator-spacing | Enable operator spacing normalization (experimental) |

Formatting Conventions

These conventions define the expected output:

• 2-space indentation (Pike stdlib convention)
• Opening brace on same line as declaration (class Foo {, void create() {)
• else joined to the preceding closing brace (} else {)
• Trailing whitespace removed and internal runs of whitespace collapsed
• Blank lines collapsed (runs of 3+ reduced to 1)
• Pike literals ({, ([, (< are treated as opening brackets

With --operator-spacing (experimental) additionally:

• Spaces around binary/assignment operators (int x=1+2; → int x = 1 + 2;)
• No space before ( in function calls (f (x) → f(x))
