peektea narrows its gaze 👀 filter-as-you-type and hidden files

Maneshwar has added filter-as-you-type and hidden file toggle features to peektea, a terminal-based file browser built with Bubble Tea. Pressing `/` activates a text input that instantly narrows visible entries, while pressing `.` toggles the display of dotfiles, with both filters composable simultaneously. The implementation uses the `textinput` component from the charmbracelet/bubbles library and a `withFilters()` function that recomputes the visible entry list based on the current filter query and hidden file state.

Hello, I'm Maneshwar. I'm building git-lrc, a Micro AI code reviewer that runs on every commit. It is free and source-available on Github. Star git-lrc to help devs discover the project. Do give it a try and share your feedback. Last time I ended with two items left on the list. Filter as you type— Bubble Tea's textinput component from bubbles is sitting there waiting Hidden file toggle— show/hide dotfiles Both ship today. Press / and start typing, the list narrows instantly. Press . and dotfiles appear. Press it again and they vanish. The / key enters filter mode. A text input appears at the bottom of the panel right above the hint bar, like vim https://github.com/vim/vim 's command line. Type anything and only matching entries stay visible. Press esc to clear it. The component doing the work is textinput from charmbracelet/bubbles https://github.com/charmbracelet/bubbles , a library of ready-made Bubble Tea components. Wiring it into the model is straightforward: type model struct { // ... filterInput textinput.Model filtering bool } When / is pressed, focus the input and return textinput.Blink , that's the command that starts the cursor blinking animation: case "/": m.filtering = true m.filterInput.Focus return m, textinput.Blink While filtering, most keystrokes go straight to the textinput's own Update . Navigation keys ↑↓ are intercepted first so you can still move the cursor while typing: if m.filtering { switch msg.String { case "up", "k": if m.cursor 0 { m.cursor-- } case "down", "j": if m.cursor < len m.entries -1 { m.cursor++ } case "esc": m.filtering = false m.filterInput.Blur m.filterInput.SetValue "" m = m.withFilters default: var tiCmd tea.Cmd m.filterInput, tiCmd = m.filterInput.Update msg m = m.withFilters return m, tiCmd } } The tiCmd returned by m.filterInput.Update carries the next blink tick. You have to pass it back out of Update , drop it and the cursor freezes. The model now stores two entry slices: allEntries everything os.ReadDir returned and entries what's visible after filters . Every filter change calls withFilters to recompute: func m model withFilters model { q := strings.ToLower m.filterInput.Value var filtered os.DirEntry for , e := range m.allEntries { if m.showHidden && strings.HasPrefix e.Name , "." { continue } if q = "" && strings.Contains strings.ToLower e.Name , q { continue } filtered = append filtered, e } m.entries = filtered if m.cursor = len m.entries { m.cursor = max 0, len m.entries -1 } return m } Hidden toggle and text filter compose naturally, you can filter by name with dotfiles visible or hidden simultaneously. Adding a third filter later means touching one function. withFilters returns a new model value rather than mutating in place, which fits cleanly with Bubble Tea's immutable-update pattern. The . key flips showHidden and calls withFilters : case ".": m.showHidden = m.showHidden m = m.withFilters needPreview = true The hint bar reflects the current state so you always know where you are: . show hidden ← dotfiles hidden . hide hidden ← dotfiles visible Navigating into a directory clears the filter, the search you ran in one folder doesn't carry over to its children. Makes the behaviour predictable without any extra state to manage. The filter input sits at the bottom of the panel, one line above the hint bar. That's the slot vim uses for its command line, /pattern , :w , :q so it feels immediately familiar. When filtering is active the text input renders there instead of the hint. When you press enter to confirm and leave filter mode, the active filter stays visible: /main esc to clear ↑/↓ →/enter o open / filter . hide hidden p preview ←/h q The hint never disappears, even in filter mode it's always one line below. The layout calculates how many rows the file list consumed and pads blank lines to push both the filter bar and the hint bar to the very bottom of the terminal. AI agents write code fast.
