MingaEditor.State.Buffers (Minga v0.1.0)

Groups buffer-related fields from EditorState.

Tracks the active buffer pid, the list of open buffers, the active index, and special (unlisted) buffers like Messages.

Summary

Types

t()

Functions

add(bs, pid)

Appends a buffer pid and makes it active.

add_background(bs, pid)

Appends a buffer pid without changing the active buffer.

remove(bs, pid)

Removes a buffer pid, selecting a neighbor as the new active.

replace_list(bs, list, idx)

Replaces the buffer list and selects the buffer at the given index.

scrub_dead_active(bs)

Removes dead pids from the buffer list and selects a live neighbor as active.

set_active_override(bs, pid)

Overrides the active buffer pid without updating the index. Use for temporary buffer swaps where the pid is not in the buffer list.

set_help(bs, pid)

Sets the help buffer pid.

switch_to(bs, idx)

Switches to the buffer at idx, wrapping around.

switch_to_pid(bs, pid)

Switches to the buffer with the given pid, if it exists in the list.

Types

t()

@type t() :: %MingaEditor.State.Buffers{
  active: pid() | nil,
  active_index: non_neg_integer(),
  help: pid() | nil,
  list: [pid()]
}

Functions

add(bs, pid)

@spec add(t(), pid()) :: t()

Appends a buffer pid and makes it active.

add_background(bs, pid)

@spec add_background(t(), pid()) :: t()

Appends a buffer pid without changing the active buffer.

remove(bs, pid)

@spec remove(t(), pid()) :: t()

Removes a buffer pid, selecting a neighbor as the new active.

replace_list(bs, list, idx)

@spec replace_list(t(), [pid()], non_neg_integer()) :: t()

Replaces the buffer list and selects the buffer at the given index.

scrub_dead_active(bs)

@spec scrub_dead_active(t()) :: t()

Removes dead pids from the buffer list and selects a live neighbor as active.

If active is nil, not a pid, or still alive, returns unchanged. If active is dead, filters all dead pids from list and selects a neighbor using the same logic as remove/2.

set_active_override(bs, pid)

@spec set_active_override(t(), pid() | nil) :: t()

Overrides the active buffer pid without updating the index. Use for temporary buffer swaps where the pid is not in the buffer list.

set_help(bs, pid)

@spec set_help(t(), pid() | nil) :: t()

Sets the help buffer pid.

switch_to(bs, idx)

@spec switch_to(t(), non_neg_integer()) :: t()

Switches to the buffer at idx, wrapping around.

switch_to_pid(bs, pid)

@spec switch_to_pid(t(), pid()) :: t()

Switches to the buffer with the given pid, if it exists in the list.
