Crate tess 

Modules

app

batch

Non-interactive write mode (--output FILE / --stdout).

cli

error

file_set

Owns the multi-file working set: a list of paths, a current-index cursor, and the navigation primitives that the colon-prompt dispatch consumes (:n, :p, :e, :d, :x, :t).

filter

format

grep

hex

xxd-style hex dump rendering. One row = 16 bytes, with offset prefix and ASCII gutter.

input

keys

Custom keybindings loaded from ~/.config/tess/keys.toml.

line_index

marks

Pure helpers for marks (m<x> / '<x>) and previous-position swap (^X^X).

open

Helper to open a file source, applying the live-mode wrapper and/or preprocessor as configured. Factored out of main.rs so that app.rs can also call it when switching files via colon-prompt commands.

preprocess

Input preprocessor: pipe the source file through a user-defined command before tess reads it. Supports --preprocess CMD (CLI) and $LESSOPEN (env var). Pipe-mode only — the command must start with |, and %s is substituted with the source file path (shell-quoted).

prettify

Content-type detection and pretty-printing for structured data.

prompt

Status-line prompt customization. Wraps the existing DisplayTemplate parser from format.rs, validating against a fixed set of prompt-only placeholder names. Rendered against a PromptContext populated by the viewport on every frame.

render

shell

“Drop TUI -> run shell command -> restore TUI” helper. Used by !cmd at runtime AND by lesskey’s !shell command bindings (Task 3).

source

terminal
