# 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
|
||||||
|
|
||||||
|
```bash
|
||||||
|
go run ./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](/home/vrubel/projects/vcom/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.
|
||||||
|
|

# Architecture
|
||||||
|
|
||||||
|
## Why this shape
|
||||||
|
|
||||||
|
The project should not become a giant `main.go` that mixes rendering, key handling, filesystem I/O and business rules. The architecture is split so the UI remains reactive and file operations stay isolated.
|
||||||
|
|
||||||
|
## High-level modules
|
||||||
|
|
||||||
|
- `cmd/vcom`
|
||||||
|
Entry point, config loading, program startup.
|
||||||
|
- `internal/config`
|
||||||
|
Config schema, defaults, search paths and TOML parsing.
|
||||||
|
- `internal/fs`
|
||||||
|
Filesystem model, directory scanning, previews and file operations.
|
||||||
|
- `internal/theme`
|
||||||
|
Theme presets and style tokens.
|
||||||
|
- `internal/ui`
|
||||||
|
Bubble Tea model, key map, pane rendering, modal flow and layout.
|
||||||
|
|
||||||
|
## State model
|
||||||
|
|
||||||
|
The Bubble Tea root model owns:
|
||||||
|
|
||||||
|
- terminal dimensions
|
||||||
|
- full config
|
||||||
|
- active browser pane
|
||||||
|
- left and right pane state
|
||||||
|
- center preview state
|
||||||
|
- transient modal state
|
||||||
|
- busy/status state for async work
|
||||||
|
|
||||||
|
This keeps the Elm-style update loop simple:
|
||||||
|
|
||||||
|
1. key or resize event arrives
|
||||||
|
2. model decides whether to mutate local state or start async work
|
||||||
|
3. async work returns a typed message
|
||||||
|
4. view renders from plain state
|
||||||
|
|
||||||
|
## Pane model
|
||||||
|
|
||||||
|
Each side pane stores:
|
||||||
|
|
||||||
|
- current path
|
||||||
|
- scanned entries
|
||||||
|
- cursor index
|
||||||
|
- scroll offset
|
||||||
|
- cached directory sizes for entries calculated on demand
|
||||||
|
|
||||||
|
This is intentionally independent from rendering details, so the pane can be unit-tested later without Lip Gloss.
|
||||||
|
|
||||||
|
## Preview pipeline
|
||||||
|
|
||||||
|
The center pane is driven only by the current selection from the active side pane.
|
||||||
|
|
||||||
|
Preview strategies:
|
||||||
|
|
||||||
|
- directory preview
|
||||||
|
Shows child entries and summary data.
|
||||||
|
- text preview
|
||||||
|
Reads up to a configured byte limit and displays text safely.
|
||||||
|
- image preview
|
||||||
|
Detects dimensions and format through standard Go image decoders.
|
||||||
|
- binary fallback
|
||||||
|
Avoids dumping junk bytes into the terminal.
|
||||||
|
|
||||||
|
Metadata shown above the preview:
|
||||||
|
|
||||||
|
- kind
|
||||||
|
- full path
|
||||||
|
- size
|
||||||
|
- created time
|
||||||
|
- modified time
|
||||||
|
- permissions
|
||||||
|
|
||||||
|
Directory size is expensive, so it is not calculated eagerly. Pressing `Space` starts an async scan and updates both:
|
||||||
|
|
||||||
|
- side-pane size column
|
||||||
|
- preview metadata widget
|
||||||
|
|
||||||
|
## Configuration design
|
||||||
|
|
||||||
|
TOML is used because:
|
||||||
|
|
||||||
|
- it is readable in terminal workflows
|
||||||
|
- comments are first-class
|
||||||
|
- optional settings can stay commented out for manual enable/disable
|
||||||
|
|
||||||
|
The example config enables only MC-like columns by default:
|
||||||
|
|
||||||
|
- `name`
|
||||||
|
- `size`
|
||||||
|
- `modified`
|
||||||
|
|
||||||
|
Additional columns are left commented out so users can literally uncomment them:
|
||||||
|
|
||||||
|
- `created`
|
||||||
|
- `permissions`
|
||||||
|
- `extension`
|
||||||
|
|
||||||
|
Other useful config areas:
|
||||||
|
|
||||||
|
- startup paths for left and right panes
|
||||||
|
- theme preset
|
||||||
|
- hidden file visibility
|
||||||
|
- sort field and reverse mode
|
||||||
|
- center pane width ratio
|
||||||
|
- confirmation behavior
|
||||||
|
- preview byte limits
|
||||||
|
- text wrapping in preview
|
||||||
|
- compact path display
|
||||||
|
|
||||||
|
## Rendering strategy
|
||||||
|
|
||||||
|
The side panes are custom-rendered rather than built on top of the generic table bubble.
|
||||||
|
|
||||||
|
Reasoning:
|
||||||
|
|
||||||
|
- MC-like directory panes are not just tables
|
||||||
|
- we need tight control over selection styling, truncation and empty states
|
||||||
|
- the center pane uses a different rendering model than the side panes
|
||||||
|
|
||||||
|
Bubble usage:
|
||||||
|
|
||||||
|
- `bubbletea`
|
||||||
|
event loop and async commands
|
||||||
|
- `bubbles/key`
|
||||||
|
declarative key bindings
|
||||||
|
- `bubbles/textinput`
|
||||||
|
mkdir modal
|
||||||
|
- `bubbles/viewport`
|
||||||
|
preview scrolling surface
|
||||||
|
- `lipgloss`
|
||||||
|
all layout and styling
|
||||||
|
|
||||||
|
## Operations
|
||||||
|
|
||||||
|
The first operational slice is intentionally MC-core:
|
||||||
|
|
||||||
|
- copy selected entry to passive pane directory
|
||||||
|
- move selected entry to passive pane directory
|
||||||
|
- create directory in active pane
|
||||||
|
- delete selected entry
|
||||||
|
- refresh active pane
|
||||||
|
|
||||||
|
These operations are dispatched asynchronously to avoid freezing the TUI on large directories.
|
||||||
|
|
||||||
|
Overwrite handling is decided before the async operation begins:
|
||||||
|
|
||||||
|
- if the target does not exist, the operation runs directly
|
||||||
|
- if the target exists and overwrite confirmation is enabled, the UI opens a modal
|
||||||
|
- if overwrite confirmation is disabled, the operation replaces the target immediately
|
||||||
|
|
||||||
|
## Theme system
|
||||||
|
|
||||||
|
Themes are token-based rather than style-object based.
|
||||||
|
|
||||||
|
Each preset defines semantic colors:
|
||||||
|
|
||||||
|
- background
|
||||||
|
- panel
|
||||||
|
- panel inactive
|
||||||
|
- border
|
||||||
|
- border active
|
||||||
|
- text
|
||||||
|
- muted text
|
||||||
|
- accent
|
||||||
|
- selection
|
||||||
|
- warning
|
||||||
|
- danger
|
||||||
|
- footer key
|
||||||
|
|
||||||
|
This allows future user-defined themes without touching UI logic.
|
||||||
|
|
||||||
|
The current UI also supports runtime theme cycling, but config remains the source of truth for default startup appearance.
|
||||||
|
|
||||||
|
## Extension points
|
||||||
|
|
||||||
|
The architecture is designed to accept later additions without a rewrite:
|
||||||
|
|
||||||
|
- multi-select and batch operations
|
||||||
|
- file viewer/editor integration
|
||||||
|
- terminal image protocols
|
||||||
|
- tab history per pane
|
||||||
|
- bookmarks and quick-jump
|
||||||
|
- sort modes
|
||||||
|
- archive browsing
|
||||||
|
- search/filter overlay
|
||||||
|
- pluggable preview providers
|
||||||
|
|
||||||
|
## Constraints worth keeping
|
||||||
|
|
||||||
|
- never calculate directory sizes during normal navigation
|
||||||
|
- never read full large files into memory for preview
|
||||||
|
- keep filesystem code out of `View()`
|
||||||
|
- keep styling decisions out of `internal/fs`
|
||||||
|
- prefer typed Tea messages over stringly-typed status events
