In a normal sed, you have to use one (and ONLY one) space between a r or w and the filename. Go-sed eats whitespace until it sees the filename. Also, in a typical sed, you need seemingly-extraneous semicolons like the one after the d below: ... but go-sed is nicer about it:

A sed implementation in Go. This project aims to be a fully compatable sed clone writen in pure Go with no dependencies. There is also a Go api that you can call to integrate this into other Go programs.

Mar 26, 2025 · Package sed implements the classic UNIX sed language in pure Go. The interface is very simple: a user compiles a program into an execution engine by calling New or NewQuiet. Then, the engine can Wrap () any io.Reader to lazily process the stream as you read from it.

go-sed is a simple and efficient command-line tool written in Go for performing basic text transformations, similar to the Unix sed command. Basic usage of go-sed: -i string. edit in-place (default "s/The/Code/g") -n string. only output a range of lines from the file (default "1p") - s/this/that/g. - G. - /^$/d. quotes.txt.

Jan 1, 2024 · Here is a simple example to perform search and replace operation in golang using sed: "fmt" "os/exec" cmd := exec.Command("sed", "-i", "s/oldstring/newstring/g", "file.txt") out, err := cmd.Output() if err != nil { panic(err) fmt.Println(string(out)) Let's perform another operation to delete a range of lines from a file: "fmt" "os/exec"

Jul 31, 2012 · I'm currently having trouble trying to run this code which is supposed to call the unix command sed to find and replace the string hello with goodbye in the file ./myfile.txt. This works fine if you run it from the command line, but if I try the same thing from my Go code....

Jun 1, 2023 · Sed-Go is an implementation of sed in Go. This sed engine can be embedded in your program, wrapping any io.Reader so that the stream is lazily processed as you read from i. This is free and open source software.

Sed-Go. An implementation of sed in Go. Just because! Status. Command-Line processing: Done. It accepts '-e', '-f', '-n' and long versions of the same. It takes '-help'. Lexer: Complete. Parser/Engine: Has every command in a typical sed now. It has: a, i, c, d, D, p, P, g, G, x, h, H, r, w, s, y, b, t, :label, n, N, q, =.

Aug 30, 2024 · 通过简洁的命令行接口和可嵌入式的库设计，Go-Sed为开发者提供了灵活且功能齐全的文本处理解决方案。 Go-Sed不遗余力地复现了sed的核心功能，包括但不限于替换 (s)、插入 (i)、删除 (d)等，并且支持正则表达式，只是采用Go语言的正则包，带来了少许语法上的差异。 其核心架构分为五大组成部分：词法分析器、解析器编译器、指令集、引擎以及条件逻辑处理，每个部分精心设计，确保高效的并发处理与简洁的内部交互。 词法分析 （lex.go）：高效地将输 …
