gtms-code

gtms-code is an independent software publisher distributing open-source projects through its GitHub repository, with a focus on practical utilities for command-line environments on Windows. Its catalog currently features psez, a modeless character-based user interface (CUI) text editor engineered specifically to address the challenges of editing Japanese and other CJK text in Windows PowerShell and SSH sessions mediated by the ConPTY console host. Unlike traditional modal editors, which require users to switch between command and insertion modes, psez adopts a modeless interaction model in which keystrokes insert text directly, lowering the learning curve for occasional users and those working in restricted terminal sessions. The editor's defining characteristic is its correct handling of full-width and double-width characters, East Asian input, and the quirks of the Windows console subsystem, an area where many terminal editors suffer from cursor misalignment, garbled rendering, or broken input processing. Typical use cases include quick configuration file edits on remote servers accessed over SSH, in-place text manipulation inside PowerShell windows, and editing documents containing mixed Japanese and ASCII content without launching a graphical application. The tool fits naturally into the broader category of terminal-based productivity software, alongside other console utilities, command-line editors, and developer tooling aimed at system administrators, software engineers, and technical users who spend significant time in text-only environments. By concentrating on a single, well-scoped problem—reliable CJK editing over ConPTY—gtms-code exemplifies a minimalist publishing approach in which small, focused tools solve specific interoperability pain points in the modern Windows terminal ecosystem. Source code, documentation, and distribution packages for psez are available through the publisher's GitHub pages, where the project can be inspected, built, and extended by the community.
