UPGRADING TO UZBL 1.0

In uzbl 1.0, lots of APIs have changed around to be more consistent with names, more logical in behaviors, and consolidated to minimize code duplication. This document aims to help users in porting configurations from previous uzbl releases to 1.0. Users using a stock setup should be able to use the default configurations.

COMMAND LINE

For uzbl-core, a URI must now use the --uri flag; the first non-flag argument is no longer interpreted as a URI (this is to avoid confusion of what should be loaded with uzbl-core --uri page1 page2).

The --embed flag is now removed and the --socket flag has been renamed to --xembed-socket. If you were using --embed before, --xembed-socket is enough now (and was before too).

DEFAULT SETUP

The default setup has gained new functionality in 1.0. This is intended as an overview of what has changed compared to previous releases.

Configuration

The socket and fifo files for uzbl-core are now dropped in $XDG_RUNTIME_DIR/uzbl if possible and /tmp/uzbl-$USER otherwise.

Some new bindings have been added:

  • <Ctrl>a: "select all"
  • <Ctrl>c: "copy selection to clipboard"
    • Adds basic support for select/paste.
  • <Shift><Ctrl>F: toggle frozen
    • When frozen is set, all network communication is denied within uzbl-core. This is useful for blocking ads after the initial page load or rogue redirects.

In follow.js, the uzbl.follow function is now available as uzbl.follow.followLinks. The code also tries to avoid breaking the same-origin-policy to minimize spurious warnings from WebKit.

The per-site-settings.py script now supports directories and will execute all .pss files in lexicographical order (a custom glob is accepted as a second argument in this case). The file format also supports @ to break all current matches and @@ to exit from the file altogether.

The insert_bookmark.sh script now removes duplicate entries.

The follow.sh script now allows for copying links to the primary selection, secondary selection, or clipboard through use of primary, secondary, or clipboard. The primary choice was previously known as clipboard. The default behavior is now to copy to the actual clipboard, not the primary selection.

COMMANDS

For 1.0, the commands in uzbl have been cleaned up. Some commands have been removed, renamed, or changed to make things more consistent. For the most part, a simple rename of the command is sufficient (js is the major exception here).

  • add_cookie
    • Change: Removed.
    • Rationale: Consolidated into the new cookie command.
    • Porting: Use cookie add.
  • auth
    • Change: Removed.
    • Rationale: Now that request is synchronous, the event manager can also return authentication results, so use a command string instead of a command which sets some magic variables.
    • Porting: Use the authentication_handler variable.
  • clear_cookies
    • Change: Removed.
    • Rationale: Consolidated into the new cookie command.
    • Porting: Use cookie clear.
  • delete_cookie
    • Change: Removed.
    • Rationale: Consolidated into the new cookie command.
    • Porting: Use cookie remove.
  • dehilight
    • Change: Removed.
    • Rationale: Consolidated into the new search command.
    • Porting: Use search clear.
  • js
    • Change: Changed to be more flexible. Now supports running JavaScript code in different contexts, not just the page.
    • Rationale: The goal is to allow for multiple JavaScript contexts to avoid getting mixed up with the page's JavaScript where possible.
    • Porting: Use js page string.
  • js_file
    • Change: Removed.
    • Rationale: Consolidated into the new js command.
    • Porting: Use js page file.
  • menu_*
    • Change: Removed.
    • Rationale: Consolidated into the menu command.
    • Porting: Use menu (add|add_separator|remove) (document|link|image|editable).
  • plugin_refresh
    • Change: Removed.
    • Rationale: Consolidated into the new plugin command.
    • Porting: Use plugin refresh.
  • plugin_toggle
    • Change: Removed.
    • Rationale: Consolidated into the new plugin command.
    • Porting: Use plugin toggle.
  • reload_ign_cache
    • Change: Removed.
    • Rationale: Consolidated into the reload command.
    • Porting: Use reload full.
  • request
    • Change: This is now a command which communicates with event managers synchronously to allow getting responses back from them.
    • Rationale: The old command was a duplicate of event and request is just about the best name available for "synchronous event".
    • Porting: Rename all old request calls to be event.
  • search
    • Change: Removed.
    • Rationale: Consolidated into the new search command.
    • Porting: Use search forward.
  • search_clear
    • Change: Removed.
    • Rationale: Consolidated into the new search command.
    • Porting: Use search reset.
  • search_reverse
    • Change: Removed.
    • Rationale: Consolidated into the new search command.
    • Porting: Use search reverse.
  • set
    • Change: '=' is no longer used in the set command.
    • Rationale: No other command needed this, so it was changed for consistency.
    • Porting: Remove '=' from set commands.
  • sh
    • Change: Removed.
    • Rationale: Renamed to have spawn_ as a prefix.
    • Porting: Use spawn_sh.
  • show_inspector
    • Change: Removed
    • Rationale: Consolidated into the inspector command.
    • Porting: Use inspector show.
  • spell_checker
    • Change: Removed.
    • Rationale: Renamed to spell to make it more verb-like.
    • Porting: Use spell.
  • sync_sh
    • Change: Removed.
    • Rationale: Renamed to have spawn_ as a prefix.
    • Porting: Use spawn_sh_sync.
  • sync_spawn
    • Change: Removed.
    • Rationale: Renamed to have spawn_ as a prefix.
    • Porting: Use spawn_sync.
  • sync_spawn_exec
    • Change: Removed.
    • Rationale: Renamed to have spawn_ as a prefix.
    • Porting: Use spawn_sync_exec.
  • toggle
    • Change: Now supports toggling user variables with 0 or 1 as the value.
    • Rationale: Missing feature.
    • Porting: Check for toggle usage on user variables without extra arguments.
  • toggle_status
    • Change: Removed.
    • Rationale: Unnecessary command.
    • Porting: Use toggle show_status.
  • toggle_zoom_type
    • Change: Removed.
    • Rationale: Unnecessary command.
    • Porting: Use toggle zoom_type.
  • zoom_in
    • Change: Removed
    • Rationale: Consolidated into the new zoom command.
    • Porting: Use zoom in.
  • zoom_out
    • Change: Removed
    • Rationale: Consolidated into the new zoom command.
    • Porting: Use zoom out.

VARIABLES

Multiple variables have been changed from integers to strings (for easier understanding of the values) or changed into commands (usually because manipulating them had weird semantics).

  • cookie_policy
    • Change: This is now a string variable.
    • Rationale: Easier to understand.
    • Porting: Use always for 0, never for 1, and first_party for 2.
  • editing_behavior
    • Change: This is now a string variable.
    • Rationale: Easier to understand.
    • Porting: Use mac for 0, windows for 1, and unix for 2.
  • geometry
    • Change: Now read-only.
    • Rationale: Setting geometry triggered "magic" better attributed to a command.
    • Porting: Use the geometry command.
  • http_debug
    • Change: This is now a string variable.
    • Rationale: Easier to understand.
    • Porting: Use none for 0, minimal for 1, headers for 2, and body for 3.
  • inject_html
    • Change: Removed.
    • Rationale: Setting inject_html triggered "magic" better attributed to a command. Also, reading from it wasn't useful.
    • Porting: Use the inject html command.
  • inject_text
    • Change: Removed.
    • Rationale: Setting inject_text triggered "magic" better attributed to a command. Also, reading from it wasn't useful.
    • Porting: Use the inject text command.
  • ssl_verify
    • Change: Renamed to ssl_policy and uses strings.
    • Rationale: Easier to understand and more consistent.
    • Porting: Use ignore for 0 and fail for 1.
  • stylesheet_uri
    • Change: Removed.
    • Rationale: Setting stylesheet_uri triggered "magic" better attributed to a command.
    • Porting: Use the css add command.
  • uri
    • Change: Now read-only.
    • Rationale: Setting uri triggered "magic" better attributed to a command.
    • Porting: Use the uri command.
  • view_mode
    • Change: Removed.
    • Rationale: Renamed to window_view_mode.
    • Porting: Use window_view_mode.
  • view_source
    • Change: Removed.
    • Rationale: Obsoleted by page_view_mode.
    • Porting: Set page_view_mode to web for 0 and source for 1.
  • zoom_type
    • Change: Removed.
    • Rationale: Redundant with zoom_text_only.
    • Porting: Use zoom_text_only.

EXPANSION

In 1.0, new variable expansion rules apply. See the documentation for more information.

  • @/ uzbl command /@
  • @/+ uzbl command file /@
  • @* uzbl js *@
  • @*+ uzbl js file *@
  • @- clean js -@
  • @-+ clean js file -@

EVENTS

Some events have been modified to help support WebKit2 or for internal changes. From the default configuration, check for usages of @on_event for these events. Also check the event manager for built-in handlers.

  • AUTHENTICATE
    • Change: Removed.
    • Rationale: The event manager can now communicate back to uzbl-core using the request command.
    • Porting: Use the authentication_handler variable.
  • DOWNLOAD_ERROR
    • Change: The first argument is now the path to the destination file which failed and the error string is available as the third argument.
    • Rationale: It should allow event managers to clean up failed downloads properly since it can be correlated with the error event.
    • Porting: Change the argument expectation of any DOWNLOAD_ERROR handlers.
  • LINK_HOVER
    • Change: The title of the hovered link is the second argument.
    • Rationale: The data is available and may be useful.
    • Porting: Expect a second argument in any LINK_HOVER event handlers.
  • LOAD_ERROR
    • Change: Cancelled loads are now LOAD_CANCELLED.
    • Rationale: Better diagnostics as to why things are happening.
    • Porting: Look for LOAD_CANCELLED for user-triggered cancellations.
  • NEW_WINDOW
    • Change: Renamed to REQ_NEW_WINDOW.
    • Rationale: Replaced with REQ_NEW_WINDOW for better interoperability with uzbl-tabbed.
    • Porting: Chain REQ_NEW_WINDOW to NEW_WINDOW or NEW_TAB depending on the application.
  • SELECTION_CHANGED
    • Change: Removed.
    • Rationale: This is no longer a builtin event. It was previously unused.
    • Porting: None.
  • VARIABLE_SET
    • Change: The float type is now double. Also, events are not sent when setting the variable failed for whatever reason, so not all set commands have an associated VARIABLE_SET event.
    • Rationale: Internally, all varargs are double anyways, so there's no sense in truncating data.
    • Porting: Use double as a type and check assumptions with set commands.
