(* a computation console - irmin store provides a tree of data objects - the tree can be navigated in the default view - the selected object can be edited or executed as an ocaml top level phrase - each execution stores any edited modifications and the command to execute that phrase in the current irmin store context as a commit message - while editing a data object wille search for the previous and next `;;` or BOF/EOF and execute the enclosed text and the commit message includes the character offsets of the executed text. - executions can modify the window system creating new windows and redirecting input focus. They define their own input handling however C-g,C-g,C-g will restore the window system to the default?? but how do we integrate this with the ocaml environment and name spaces?? some options: - always wrap execution units from data objects in some sort of local namespace so opens are not global? - dig into the toplevel environment and manipulate it, this will also help with things like completion and context help *) open Lwt.Infix module F = Fmt module Input = struct open CamomileLibrary open Zed_edit open CamomileLibrary (** Type of key code. *) type code = | Char of UChar.t (** A unicode character. *) | Enter | Escape | Tab | Up | Down | Left | Right | F1 | F2 | F3 | F4 | F5 | F6 | F7 | F8 | F9 | F10 | F11 | F12 | Next_page | Prev_page | Home | End | Insert | Delete | Backspace | Unknown | None module KeymodSet = struct type t = Shift | Ctrl | Meta | Fn let compare (x : t) (y : t) = compare x y end module Keymod = Set.Make (KeymodSet) let modset = Keymod.of_list type key = {mods: Keymod.t; code: code} module Key = struct type t = key let compare = compare end module Bind = struct (* parts stolen from lambda-term/src/lTerm_{edit,key}.ml{,i} *) module S = Zed_input.Make (Key) include S type action = Custom of (unit -> unit) | Zed of Zed_edit.action type t = action list S.t type resolver = action list S.resolver type result = action list S.result type state = { mutable bindings: t ; mutable state: result ; mutable last_keyseq: key list ; mutable last_actions: action list } let add events action bindings = let events = List.map (fun (m, k) -> {mods= Keymod.of_list m; code= Char (UChar.of_char k)} ) events in S.add events action bindings let default_resolver b = resolver [pack (fun (x : action list) -> x) b] let get_resolver result default = match result with Continue r -> r | _ -> default let init bindings = {bindings; state= S.Rejected; last_keyseq= []; last_actions= []} end (* stolen from lambda-term/src/lTerm_{edit,key}.ml{,i} *) let string_of_code = function | Char ch -> Printf.sprintf "Char 0x%02x" (UChar.code ch) | Enter -> "Enter" | Escape -> "Escape" | Tab -> "Tab" | Up -> "Up" | Down -> "Down" | Left -> "Left" | Right -> "Right" | F1 -> "F1" | F2 -> "F2" | F3 -> "F3" | F4 -> "F4" | F5 -> "F5" | F6 -> "F6" | F7 -> "F7" | F8 -> "F8" | F9 -> "F9" | F10 -> "F10" | F11 -> "F11" | F12 -> "F12" | Next_page -> "Next_page" | Prev_page -> "Prev_page" | Home -> "Home" | End -> "End" | Insert -> "Insert" | Delete -> "Delete" | Backspace -> "Backspace" | Unknown -> "Unknown" | None -> "None" let to_string key = Printf.sprintf "{ control = %B; meta = %B; shift = %B; fn = %B; code = %s }" (Keymod.mem Ctrl key.mods) (Keymod.mem Meta key.mods) (Keymod.mem Shift key.mods) (Keymod.mem Fn key.mods) (string_of_code key.code) let to_string_compact key = let buffer = Buffer.create 32 in if Keymod.mem Ctrl key.mods then Buffer.add_string buffer "C-" ; if Keymod.mem Meta key.mods then Buffer.add_string buffer "M-" ; if Keymod.mem Shift key.mods then Buffer.add_string buffer "S-" ; if Keymod.mem Fn key.mods then Buffer.add_string buffer "Fn-" ; ( match key.code with | Char ch -> let code = UChar.code ch in if code <= 255 then match Char.chr code with | ( 'a' ..
