# The framework-free half of tty7: wire protocol, session daemon, PTY, the
# native SSH engine, and the domain model the headless `tty7-server` shares with
# this GUI. Everything that does *not* need gpui lives there.
# `gssapi` is off in tty7-core's defaults (a static musl `tty7-server` cannot
# link the system krb5 it binds); the GUI, which builds against a real desktop
# toolchain, turns it on so managed SSH connections keep offering
# `gssapi-with-mic` exactly as before.
#
# `remote-install` is off there for the same shape of reason: it pulls an HTTPS
# client used only to *download* a `tty7-server` onto a remote machine
# (decision D5). The server binary is the thing being downloaded, so it can
# never take that path; the GUI, which is the client that pushes it, can.

# Our fork of Zed's alacritty_terminal fork: the VT parser + grid

# to render the live mirror, and tty7-cli to turn a captured pane back into text
# (`tty7 capture --plain`). The daemon parses nothing; it is a byte pipe, and its
# PTY is driven by `portable-pty`.
#
# The `tty7` branch is Zed's `fcf32fe` (the rev Zed pins) plus two commits, both
# still missing from alacritty master as of 852e971:
#
# 1. `push_keyboard_mode` capped its stack by removing from `title_stack` instead
#    of `keyboard_mode_stack` — a copy-paste slip from `push_title` that compiles
#    because both are `Vec`s. With `kitty_keyboard` on (see
#    `terminal_config_from_user`) every overflowing push silently drops a saved
#    title, and once the title stack is empty `Vec::remove(0)` panics — 4097
#    unpopped `CSI > 1 u` pushes, about 20KB of output, kill the reader thread and
#    freeze the pane.
# 2. `input` reserves columns per `char`, so an emoji written as base + U+FE0F
#    (`❤️`, `🗂️`, `⚠️` — any base whose East Asian Width is Neutral) gets one
#    column instead of two and shifts the rest of the line left by one. The fork
#    re-scores the sequence with `UnicodeWidthStr` and widens the cell (issue
#    #203).

# ---- gpui fork ------------------------------------------------------------
# Our `tty7` branch (cut from the pinned upstream rev, three commits on top) carries:
#
# 1. `prefers_ime_for_printable_keys` takes the keystroke, so an input handler can
#    answer per key instead of per view. tty7 needs it for Option-as-Meta — macOS
#    routes ⌥-chords to the IME whenever a CJK input source is active, and without
#    the keystroke there is no way to decline just those chords (see
#    `terminal::input::prefers_ime_for_printable_keys`, issue #177).
#
# 2. gpui's Windows backend rasterizes a font-fallback run with the face
#    DirectWrite actually shaped it with, instead of re-deriving one from the
#    face's family/weight/style. The round trip mapped DirectWrite's italic to
#    oblique, so italic CJK — which every pane reaches through the fallback chain,
#    Hack having no CJK — drew a *different* face's outlines at the shaped glyph
#    indices. Every character rendered as an unrelated character, one for one,
#    which reads as mojibake rather than as a font bug.
#
# 3. resvg/usvg bumped 0.45 → 0.47 so gpui's SVG stack unifies with the resvg
#    tty7 pins directly above (follow-up to the #227 dependabot bump).
#
# Patching by source rather than editing the `gpui`/`gpui_platform` pins above is
# deliberate: `gpui-component` declares its own `gpui` from the upstream URL, and
# a plain pin swap would put two incompatible copies of gpui in the tree. `[patch]`
# rewrites the source for every dependent at once, so the fork's sibling crates
# (`gpui_macos`, `gpui_web`, …) come along through their in-repo path deps.
#
# When bumping the upstream rev: rebase the fork's `tty7` branch onto the new rev,
# push, then update the `rev` pins above — the branch here follows automatically.
