[CHANNEL]
    Which channel shall we watch? Channels provide predefined configurations including source commands, preview commands, UI settings, and more. To list available channels, use the `list-channels` subcommand. To pull the latest collection of channels from github, use the `update-channels` subcommand.

[PATH]
    The working directory to start the application in. Defaults to the current directory.

SOURCE

-s, --source-command <STRING>
    Source command to use for the current channel. When a channel is specified: This overrides the command defined in the channel prototype. When no channel is specified: This creates an ad-hoc channel with the given command. Example: `find . -name '*.rs'`

--ansi
    Whether tv should extract and parse ANSI style codes from the source command output. This is useful when the source command outputs colored text or other ANSI styles and you want `tv` to preserve them in the UI. It does come with a slight performance cost but which should go mostly unnoticed for typical human interaction workloads. Example: `tv --source-command="echo -e 'Red'" --ansi`

--source-display <STRING>
    Source display template to use for the current channel. When a channel is specified: This overrides the display template defined in the channel prototype. When no channel is specified: This flag requires --source-command to be set. The template is used to format each entry in the results list. Example: `{split:/:-1}` (show only the last path segment)

--source-output <STRING>
    Source output template to use for the current channel. When a channel is specified: This overrides the output template defined in the channel prototype. When no channel is specified: This flag requires --source-command to be set. The template is used to format the final output when an entry is selected. Example: "{}" (output the full entry)

--source-entry-delimiter <STRING>
    The delimiter byte to use for splitting the source's command output into entries. This can be useful when the source command outputs multiline entries and you want to rely on another delimiter to split the entries such a null byte or a custom character.

PREVIEW

-p, --preview-command <STRING>
    Preview command to use for the current channel. When a channel is specified: This overrides the preview command defined in the channel prototype. When no channel is specified: This enables preview functionality for the ad-hoc channel. Example: "cat {}" (where {} will be replaced with the entry) Parts of the entry can be extracted positionally using the `delimiter` option. Example: "echo {0} {1}" will split the entry by the delimiter and pass the first two fields to the command.

--preview-header <STRING>
    Preview header template When a channel is specified: This overrides the header defined in the channel prototype. When no channel is specified: This flag requires --preview-command to be set. The given value is parsed as a `MultiTemplate`. It is evaluated for every entry and its result is displayed above the preview panel.

--preview-footer <STRING>
    Preview footer template When a channel is specified: This overrides the footer defined in the channel prototype. When no channel is specified: This flag requires --preview-command to be set. The given value is parsed as a `MultiTemplate`. It is evaluated for every entry and its result is displayed below the preview panel.

--cache-preview
    Whether to cache the preview command output for each entry. This can be useful when the preview command is expensive to run and you want to avoid running it multiple times for the same entry. This is enabled by default since most channels will benefit from it. This can be disabled for special cases e.g. where the preview command output changes frequently and/or you want live udpates.

--preview-offset <STRING>
    A preview line number offset template to use to scroll the preview to for each entry. When a channel is specified: This overrides the offset defined in the channel prototype. When no channel is specified: This flag requires --preview-command to be set. This template uses the same syntax as the `preview` option and will be formatted using the currently selected entry.

--no-preview
    Disable the preview panel entirely on startup. This flag works identically in both channel mode and ad-hoc mode. When set, no preview panel will be shown regardless of channel configuration or preview-related flags.

--hide-preview
    Hide the preview panel on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. The preview remains functional and can be toggled visible later.

--show-preview
    Show the preview panel on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. This overrides any channel configuration that might have it disabled.

--preview-border <PREVIEW_BORDER>
    Sets the preview panel border type. Available options are: `none`, `plain`, `rounded`, `thick`.
    [possible values: none, plain, rounded, thick]

--preview-padding <STRING>
    Sets the preview panel padding. Format: `top=INTEGER;left=INTEGER;bottom=INTEGER;right=INTEGER` Example: `--preview-padding='top=1;left=2;bottom=1;right=2'`

--hide-preview-scrollbar
    Hide preview panel scrollbar.

--preview-size <INTEGER>
    Percentage of the screen to allocate to the preview panel (1-99). When a channel is specified: This overrides any `preview_size` defined in configuration files or channel prototypes. When no channel is specified: This flag requires --preview-command to be set.

INPUT

-i, --input <STRING>
    Input text to pass to the channel to prefill the prompt. This flag works identically in both channel mode and ad-hoc mode. This can be used to provide a default value for the prompt upon startup.

--input-header <STRING>
    Input field header template. When a channel is specified: Overrides the input header defined in the channel prototype. When no channel is specified: Sets the input header for the ad-hoc channel. The given value is parsed as a `MultiTemplate`. It is evaluated against the current channel name and the resulting text is shown as the input field title. Defaults to the current channel name when omitted.

--input-prompt <STRING>
    Input prompt string When a channel is specified: This overrides the prompt defined in the channel prototype. When no channel is specified: Sets the input prompt for the ad-hoc channel. The given value is used as the prompt string shown before the input field. Defaults to ">" when omitted.

--input-position <INPUT_POSITION>
    Input bar position. Sets whether the input panel is shown at the top or bottom of the UI.
    [possible values: top, bottom]

--input-border <INPUT_BORDER>
    Sets the input panel border type.
    [possible values: none, plain, rounded, thick]

--input-padding <STRING>
    Sets the input panel padding. Format: `top=INTEGER;left=INTEGER;bottom=INTEGER;right=INTEGER` Example: `--input-padding='top=1;left=2;bottom=1;right=2'`

UI

--no-status-bar
    Disable the status bar entirely on startup. This flag works identically in both channel mode and ad-hoc mode. When set, no status bar will be shown regardless of channel configuration or status bar-related flags.

--hide-status-bar
    Hide the status bar on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. The status bar remains functional and can be toggled visible later.

--show-status-bar
    Show the status bar on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. This overrides any channel configuration that might have it disabled.

--results-border <RESULTS_BORDER>
    Sets the results panel border type.
    [possible values: none, plain, rounded, thick]

--results-padding <STRING>
    Sets the results panel padding. Format: `top=INTEGER;left=INTEGER;bottom=INTEGER;right=INTEGER` Example: `--results-padding='top=1;left=2;bottom=1;right=2'`

--layout <LAYOUT>
    Layout orientation for the UI. When a channel is specified: Overrides the layout/orientation defined in the channel prototype. When no channel is specified: Sets the layout orientation for the ad-hoc channel.
    [possible values: landscape, portrait]

--no-remote
    Disable the remote control. This flag works identically in both channel mode and ad-hoc mode. This will disable the remote control panel and associated actions entirely. This is useful when the remote control is not needed or when the user wants `tv` to run in single-channel mode (e.g. when using it as a file picker for a script or embedding it in a larger application).

--hide-remote
    Hide the remote control on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. The remote control remains functional and can be toggled visible later.

--show-remote
    Show the remote control on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode.

--no-help-panel
    Disable the help panel entirely on startup. This flag works identically in both channel mode and ad-hoc mode. When set, no help panel will be shown regardless of channel configuration or help panel-related flags.

--hide-help-panel
    Hide the help panel on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. The help panel remains functional and can be toggled visible later.

--show-help-panel
    Show the help panel on startup (only works if feature is enabled). This flag works identically in both channel mode and ad-hoc mode. This overrides any channel configuration that might have it disabled.

--ui-scale <INTEGER>
    Change the display size in relation to the available area. This flag works identically in both channel mode and ad-hoc mode. This will crop the UI to a centered rectangle of the specified percentage of the available area.

--height <INTEGER>
    Height in lines for non-fullscreen mode. This flag works identically in both channel mode and ad-hoc mode. When specified, the picker will be displayed as a non-fullscreen interface.

--width <INTEGER>
    Width in columns for non-fullscreen mode. This flag can only be used in combination with --inline or --height. When specified, the picker will be constrained to the specified width.

--inline
    Use all available empty space at the bottom of the terminal as an inline interface. This flag works identically in both channel mode and ad-hoc mode. When enabled, the picker will be displayed as an inline interface that uses all available empty space at the bottom of the terminal. If there is insufficient space to meet the minimum height the terminal will scroll.

BEHAVIOR

-t, --tick-rate <INT>
    The application's tick rate. This flag works identically in both channel mode and ad-hoc mode. The tick rate is the number of times the application will update per second. This can be used to control responsiveness and CPU usage on very slow machines or very fast ones but the default should be a good compromise for most users.

--watch <FLOAT>
    Watch mode: reload the source command every N seconds. When a channel is specified: Overrides the watch interval defined in the channel prototype. When no channel is specified: Sets the watch interval for the ad-hoc channel. When set to a positive number, the application will automatically reload the source command at the specified interval. This is useful for monitoring changing data sources. Set to 0 to disable (default).

--autocomplete-prompt <STRING>
    Try to guess the channel from the provided input prompt. This flag automatically selects channel mode by guessing the appropriate channel. It conflicts with manually specifying a channel since it determines the channel automatically. This can be used to automatically select a channel based on the input prompt by using the `shell_integration` mapping in the configuration file.

--exact
    Use substring matching instead of fuzzy matching. This flag works identically in both channel mode and ad-hoc mode. This will use substring matching instead of fuzzy matching when searching for entries. This is useful when the user wants to search for an exact match instead of a fuzzy match e.g. to improve performance.

--select-1
    Automatically select and output the first entry if there is only one entry. This flag works identically in both channel mode and ad-hoc mode. Note that most channels stream entries asynchronously which means that knowing if there's only one entry will require waiting for the channel to finish loading first. For most channels and workloads this shouldn't be a problem since the loading times are usually very short and will go unnoticed by the user.

--take-1
    Take the first entry from the list after the channel has finished loading. This flag works identically in both channel mode and ad-hoc mode. This will wait for the channel to finish loading all entries and then automatically select and output the first entry. Unlike `select_1`, this will always take the first entry regardless of how many entries are available.

--take-1-fast
    Take the first entry from the list as soon as it becomes available. This flag works identically in both channel mode and ad-hoc mode. This will immediately select and output the first entry as soon as it appears in the results, without waiting for the channel to finish loading. This is the fastest option when you just want the first result.

KEYBINDINGS

-k, --keybindings <STRING>
    Keybindings to override the default keybindings. This flag works identically in both channel mode and ad-hoc mode. This can be used to override the default keybindings with a custom subset. The keybindings are specified as a semicolon separated list of keybinding expressions using the configuration file formalism. Example: `tv --keybindings='quit="esc";select_next_entry=["down","ctrl-j"]'`

--expect <STRING>
    Keys that can be used to confirm the current selection in addition to the default ones (typically `enter`). When this is set, confirming the selection will first output an extra line with the key that was used to confirm the selection before outputting the selected entry. Example: `tv --expect='ctrl-q'` will output `ctr-q\n<selected_entry>` when `ctrl-q` is pressed to confirm the selection.

CONFIGURATION

--config-file <PATH>
    Provide a custom configuration file to use. This flag works identically in both channel mode and ad-hoc mode.

--cable-dir <PATH>
    Provide a custom cable directory to use. This flag works identically in both channel mode and ad-hoc mode.

HISTORY

--global-history
    Use global history instead of channel-specific history. This flag only works in channel mode. When enabled, history navigation will show entries from all channels. When disabled (default), history navigation is scoped to the current channel.
