BREAKING CHANGE: No more builtin previews which means channels currently using `:files:` and other builtins will now need to rely on external tools (examples to come).
- tv's default channel (when lauching `tv`) is now configurable via the
`default_channel` configuration option
- add `RUST_BACKTRACE=1` and `--nocapture` to ci testing for better
debugging
- remove all builtin channels and associated glue code as well as the
`ToCliChannel` and `ToUnitChannel` derive macros
- recode all builtin channels using shell commands (along with `fd`,
`bat`, and `rg`)
- add support for interactive shell commands inside cable channels
- drop the `send_to_channel` feature until further notice (will be
reimplemented later on in a more generic and customizable way)
BREAKING CHANGE: mode keybindings dropped in favor of a global table
**What this means in practice:**
```toml
[keybindings.Channel]
quit = ["esc", "ctrl-c"]
# ...
[keybindings.RemoteControl]
quit = ["esc", "ctrl-c"]
# ...
[keybindings.SendToChannel]
quit = ["esc", "ctrl-c"]
# ...
```
are being replaced with
```toml
[keybindings]
quit = ["esc", "ctrl-c"]
# ...
```
Mode keybindings were I believe a premature optimization which only
brought additional complexity and redundancy to the code and did not
provide any real functionality in the current state of things for end
users.
Before:
```toml
[shell_integration.commands]
# Add your commands here. Each key is a command that will trigger tv with the
# corresponding channel as value.
# Example: say you want the following prompts to trigger the following channels
# when pressing <CTRL-T>:
# `git checkout` should trigger the `git-branches` channel
# `ls` should trigger the `dirs` channel
# `cat` should trigger the `files` channel
#
# You would add the following to your configuration file:
# ```
# [shell_integration.commands]
# "git checkout" = "git-branch"
# "ls" = "dirs"
# "cat" = "files"
# ```
# environment variables
"export" = "env"
"unset" = "env"
# dirs channel
"cd" = "dirs"
"ls" = "dirs"
"rmdir" = "dirs"
# files channel
"cat" = "files"
"less" = "files"
"head" = "files"
"tail" = "files"
"vim" = "files"
"bat" = "files"
# git-diff channel
"git add" = "git-diff"
# git-branch channel
"git checkout" = "git-branch"
"git branch -d" = "git-branch"
# docker-images channel
"docker run" = "docker-images"
# gitrepos channel
"nvim" = "git-repos"
```
After
```toml
[shell_integration.channel_triggers]
# Add your channel triggers here. Each key is a channel that will be triggered
# by the corresponding commands.
# Example: say you want the following commands to trigger the following channels
# when pressing <CTRL-T>:
# `git checkout` should trigger the `git-branches` channel
# `ls` should trigger the `dirs` channel
# `cat` and `cp` should trigger the `files` channel
#
# You would add the following to your configuration file:
# ```
# [shell_integration.channel_triggers]
# "git-branches" = ["git checkout"]
# "dirs" = ["ls"]
# "files" = ["cat", "cp"]
# ```
"env" = ["export", "unset"]
"dirs" = ["cd", "ls", "rmdir"]
"files" = ["cat", "less", "head", "tail", "vim", "bat"]
"git-diff" = ["git add"]
"git-branch" = ["git checkout", "git branch -d"]
"docker-images" = ["docker run"]
"git-repos" = ["nvim"]
```
