Implementation Reference
- src/index.ts:739-758 (handler)The handler function for the perl_edit tool. It executes a Perl one-liner script on the specified file, with options for backup and multiline processing.
case 'perl_edit': { const { file, script, backup = true, multiline = false } = args; if (!existsSync(file)) { throw new Error(`File not found: ${file}`); } const backupExt = backup ? '.bak' : ''; const multilineFlag = multiline ? '-0777 ' : ''; const perlCmd = `perl -i${backupExt} ${multilineFlag}-pe '${script}' '${file}'`; await execAsync(perlCmd); return { content: [{ type: 'text', text: `Successfully edited ${file} using Perl${backup ? ' (backup created as .bak)' : ''}` }] }; } - src/index.ts:175-202 (registration)Registers the perl_edit tool in the listTools response, including its name, description, and input schema.

perl_edit: `perl_edit - Perl one-liner execution =================================== Direct access to perl's text processing power. Examples: // Simple substitution perl_edit({ file: "data.txt", script: "s/foo/bar/g" }) // Delete lines perl_edit({ file: "log.txt", script: "$_ = '' if /DEBUG/" }) // Transform to uppercase perl_edit({ file: "names.txt", script: "$_ = uc" }) // Complex multiline operations perl_edit({ file: "code.js", script: "s/function\\s+(\\w+)\\s*\\(/const $1 = (/g", multiline: true }) Tips: - Use $_ for the current line - Escape backslashes in regex - multiline mode slurps entire file `,
