EditPro

简体中文 | English

EditPro is a fast, cross-platform text editing SDK and CLI for coding agents and vibecoding tools. The editing core is pure Go, byte-exact, dependency-free, and available everywhere Go can compile it.

Features

• Replace one or every non-overlapping occurrence of exact text.
• Validate the expected match count before changing a file.
• Insert at file start, file end, before a line, or after a line.
• Preserve LF/CRLF line endings, with a raw byte insertion mode when required.
• Commit through a same-directory temporary file while preserving permissions.
• Reject symbolic-link destinations to avoid surprising link replacement.
• Use Go's architecture-optimized byte routines, including AVX2/SSE on amd64 and NEON on arm64 when available.
• Ship native CLI packages for npm, PyPI, and release archives.

Installation

With Go:

go install github.com/startvibecoding/editpro/cmd/editpro@latest

With npm:

npm install --global @startvibecoding/editpro

With pip or pipx:

pipx install editpro
# or: pip install editpro

CLI

Replace all matches while verifying that the source occurs exactly twice:

editpro edit -file main.go -old oldName -new newName -expect 2

Insert before line 10, preserving the file's detected line ending:

editpro insert -file main.go -at before -line 10 -text '// generated'

Read from stdin and write to stdout:

editpro edit -file - -old oldName -new newName < main.go > updated.go

Use -old-file, -new-file, or -text-file for multiline or arbitrary content. Use -dry-run to print a result without changing a file and -json for machine-readable operation metadata.

See the CLI reference.

Go SDK

package main

import "github.com/startvibecoding/editpro"

func update(source []byte) ([]byte, error) {
    result, err := editpro.Replace(
        source,
        []byte("oldName"),
        []byte("newName"),
        editpro.ReplaceOptions{ExpectedMatches: 1, RequireMatch: true},
    )
    if err != nil {
        return nil, err
    }
    return result.Data, nil
}

The in-memory API has no filesystem side effects. EditFile and InsertFile provide safe file commits. See the SDK reference.

Supported Packages

Release archives and npm packages cover Linux amd64/arm64/loong64/ppc64le/s390x/riscv64, macOS amd64/arm64, Windows amd64/arm64, FreeBSD amd64/arm64, OpenBSD amd64/arm64, and NetBSD amd64.

PyPI wheels cover Linux amd64/arm64/ppc64le/s390x, macOS amd64/arm64, and Windows amd64/arm64. Platforms without widely portable wheel tags remain available through npm, Go installation, or release archives.
