vcom

vcom is a terminal file manager inspired by Midnight Commander and built on top of Charm's TUI stack.

The layout is:

• left browser pane
• right browser pane

The key difference from classic mc is the inspect mode on i. It temporarily replaces the inactive pane with a preview/info panel for the active side selection:

• directory: child entries
• text file: text preview
• image: metadata and dimensions
• binary or unsupported file: safe fallback preview

Goals

• MC-like browsing and function-key workflow
• configurable column layout
• pleasant default styling
• readable, editable config with commented-out optional features
• clean architecture for async file operations and previews

Current feature set

• MC-like two-pane layout by default
• preview/info mode on i
• left/right file browsers
• preview with top metadata widget
• themes with catppuccin-mocha as default
• runtime theme cycling with t
• configurable visible columns
• hidden files shown by default
• hidden files toggle with .
• browser sort cycling with s
• directory size calculation on Space
• overwrite confirmation before copy or move
• pager on F3 and editor on F4 when available
• basic F5 copy, F6 move, F7 mkdir, F8 delete, F10 quit

Controls

• Tab: switch active browser pane
• Enter: open directory
• Backspace or Left: go to parent directory
• i: replace inactive pane with info/preview for the active pane selection
• Space: calculate selected directory size
• .: toggle hidden entries
• s: cycle sort mode
• t: cycle theme
• F3: open selected file in $PAGER if available, otherwise stay in center preview
• F4: open selected file in $EDITOR
• F5: copy to passive pane path
• F6: move to passive pane path
• F7: create directory in active pane
• F8: delete selected entry
• F10: quit

Run

go run ./cmd/vcom

To build a local binary:

go build -o vcom ./cmd/vcom

Optional config file lookup order:

1. -config /path/to/vcom.toml
2. ./vcom.toml
3. ./config/vcom.toml
4. $XDG_CONFIG_HOME/vcom/vcom.toml
5. ~/.config/vcom/vcom.toml

Themes

Built-in presets:

• catppuccin-mocha
• tokyo-night
• gruvbox-dark
• nord-frost

The sample config in vcom.toml is intentionally written so optional columns and sort variants can be uncommented by hand.

Notes

• File creation time depends on filesystem and OS support. When unavailable the UI shows n/a.
• Real inline image rendering is intentionally not enabled yet because terminal support is fragmented. The current architecture keeps that as an isolated preview backend to add later.

More detail is in docs/architecture.md.

Installation

NixOS / Nix

Run directly from the flake:

nix run github:vrubelroman/vcom?ref=<tag>

Install into the current profile:

nix profile add github:vrubelroman/vcom?ref=<tag>

nix profile add installs vcom into the current user's Nix profile. It does not edit configuration.nix, does not rebuild NixOS, and does not make the package a declarative system package.

Debian / Ubuntu

Release builds include a .deb artifact. Install it with:

sudo apt install ./vcom_<version>_amd64.deb

Arch Linux

A PKGBUILD is included in the repository. Build it with:

makepkg -si

Releases

Tagging a version like v0.1.0 triggers the GitHub Actions release workflow:

• runs go test ./...
• vendors Go modules for reproducible packaging
• builds the release binary
• builds the .deb package with dpkg-deb
• publishes release artifacts to GitHub Releases

Release artifacts include:

• vcom-<tag>-x86_64-unknown-linux-gnu.tar.gz
• vcom_<version>_amd64.deb
• vcom-<tag>-checksums.txt
