FTP/SFTP Explorer (NppFTP style)

English · Türkçe sürüm: README.tr.md

Developer: Sanater

An FTP client that brings the workflow of NppFTP (the Notepad++ plugin) to VS Code: define a profile → connect → click a file in the remote tree → edit → save, and it uploads itself.

No NppFTP code was used — only its behaviour and dialog layout were taken as a reference. This extension is written from scratch in TypeScript.

Features

On top of that:

• SSH terminal — opens a shell on the same server (not in NppFTP).
• Matching tag highlighting — Notepad++'s own feature, brought along too.
• Drag & drop: drop local files onto the tree to upload, drag inside the tree to move.
• Passwords and SSH key passphrases go to the operating system credential store (VS Code SecretStorage), never into the profile file.
• Silent reconnect when the connection drops while saving.
• Status bar indicator, keep-alive, timeout, ASCII/binary transfer mode.
• English and Turkish user interface.

Installation

From the Marketplace: open the Extensions panel (Ctrl+Shift+X), search for FTP/SFTP Explorer and click Install.

From a .vsix file: Extensions panel → ... menu → Install from VSIX..., or from a terminal:

code --install-extension ftp-explorer-<version>.vsix

Reload the window afterwards (Ctrl+Shift+P → Developer: Reload Window). The FTP icon appears in the activity bar.

To build from source see Development below.

Language

The extension speaks English and Turkish. By default it follows the VS Code display language; to pin one explicitly:

"ftpx.language": "en"    // "auto" (default) | "en" | "tr"

This setting covers messages, dialogs, the profile window and the message window. Command and menu titles are translated through the VS Code platform mechanism instead, so those follow the display language (Ctrl+Shift+P → Configure Display Language) and require the matching language pack.

Getting started

1. Click the FTP icon in the activity bar.
2. Open Profile Settings, press Add and fill in the protocol, host, username and password. Then Save and Connect.
3. Click a file in the remote tree — it is downloaded to a local cache and opened in the editor.
4. Edit and press Ctrl+S — the file is uploaded back automatically.

To upload the current file manually: Ctrl+Alt+U (FTP: Upload Current File).

Profile fields

SSH terminal

You do not need a separate program to run php artisan cache:clear after uploading a file. An interactive shell opens on the same server, inside the VS Code terminal panel — no PuTTY or OpenSSH installation required.

Credentials come from the same place as the FTP/SFTP connection, and are not asked for again if the profile is already connected. Servers requiring keyboard-interactive authentication are supported. Terminal resizes are forwarded to the server, so full-screen programs such as top, htop and nano work correctly. Multi-byte UTF-8 characters survive chunk boundaries.

Which profiles can use it?

• SFTP profiles automatically — same host, port and credentials.
• FTP / FTPS / FTPES profiles once you enable the SSH terminal section in the profile settings. Port (22 by default) and username can be overridden; the FTP password is reused. If you need key-based authentication, create a separate profile using the SFTP protocol.

Matching tag highlighting

Move the cursor into a tag and both the opening and the closing tag stand out:

<div class="row">          ← highlighted as well while the cursor is in the </div> below
    <div class="col-12">
        @if($section->body)     ← @if / @endif pairs are matched too
            {!! $section->body !!}
        @endif
    </div>
</div>                     ← cursor here

Three highlight layers

Notepad++'s look is made of three separate layers; each can be toggled individually:

How much gets coloured? (ftpx.tagHighlight.scope)

In the default tag mode attribute values are not painted. This matters for Tailwind projects where a single tag can exceed 300 characters:

<!-- scope: "tag" (default) -->   <div class="..." style="...">  →  <div  and  >
<!-- scope: "name" -->            just  div
<!-- scope: "full" -->            the whole tag (Notepad++'s "highlight tag attributes" look)

Measured on a real 212-line Tailwind Blade file: full painted 76 characters per tag on average and 356 in the worst case; tag paints 11 on average, 19 at worst.

What the scanner handles

• < inside <!-- --> comments, <script> / <style> / <textarea> content and <?php ... ?> blocks is not treated as a tag.
• A quoted > such as <a title="a > b"> does not end the tag.
• In-tag Blade expressions like <div {{ $attrs }} class="{!! $c !!}"> are skipped.
• Void elements (<br>, <img>, <input>) and <x /> are not openings.
• Unclosed <li> / <p> tags do not break the enclosing pair.
• Blade component tags such as <x-layout.app> and <x-slot:head> are supported.
• Attribute scanning keeps Vue/Alpine forms: :class, @click, @click.prevent, x-on:click.prevent, v-if, #slot.

Blade block directives are matched as well (ftpx.tagHighlight.highlightBladeDirectives): @if, @unless, @isset, @for, @foreach, @forelse, @while, @switch, @section, @push, @prepend, @once, @verbatim, @php, @auth, @guest, @can, @cannot, @canany, @error, @production, @env, @component, @slot, @fragment, @session and @hasSection. Single-line forms (@section('title', 'Page'), @php($x = 1)) do not open a block; @@if escapes and text like [email protected] are not directives.

Development

npm install
npm run compile

Open this folder in VS Code and press F5: a separate "Extension Development Host" window starts so you can try your changes without touching the installed version.

See PUBLISHING.md in the repository for packaging and publishing.

Tests

npm test

test/sftp-server.js starts a real in-process SFTP + SSH server; test/smoke.js verifies connecting, listing, stat, downloading (including progress reporting), uploading, mkdir, rename, chmod and recursive deletion end to end. On the SSH side it covers opening a shell, running commands, multi-byte character integrity, window-size propagation, the initial directory (including quote escaping) and the wrong-password path. It also covers every corner case of the tag/directive scanner (comments, <script>, quoted >, void elements, @section forms, @@ escapes) and the consistency of the translation bundles (key parity, empty strings, placeholder agreement).

Known limitations

• Active (PORT) FTP mode is not supported. basic-ftp only uses passive mode (PASV/EPSV); if a profile selects active mode a warning is logged and passive mode is used.
• SSH host keys are not verified. The server key fingerprint is logged at debug level but is not compared against known_hosts.
• ASCII mode does not rely on the server's TYPE A behaviour; line endings are converted locally instead (to the OS convention on download, to LF on upload). Binary content is detected and left untouched.
• Only one connection at a time (same as NppFTP).
• FTP has no single-file stat command, so "Properties" reads from the parent directory listing; some servers do not report permissions or ownership.
