### CONFIGURATION / CONTROL:
-The general idea is that uzbl by default is very bare bones. you can send it commands to update settings and perform actions, through various interfaces. (TODO: some default settings)
-For examples, please see the sample config(s).
+The general idea is that uzbl by default is very bare bones. you can send it commands to update settings and perform actions, through various interfaces.
+There is a limited default configuration. Please see config.h to see what it contains.
+By default, there are *no* keybinds defined at all. (Default keybinds would work counterproductive when you try to customize)
+For examples of the possibilities what you can do, please see the sample config(s).
There are several interfaces to interact with uzbl:
* uzbl --config <filename>: <filename> will be read line by line, and the commands in it will be executed. useful to configure uzbl at startup.
insert mode: keystrokes are not interpreted so you can enter text into html forms
Press ESC/i to toggle command/insert mode
But if you don't like modal interfaces, you can set `always_insert_mode` and configure a modkey to execute the commands. (emacs style).
-* FIFO & socket file: if enabled by setting their paths through one of the above means, you can have socket and fifo files available which are very useful to programatically (from scripts etc) to uzbl.
+ There is also support for "chained" commands (multiple characters long) (with backspace/esc shortcuts), and keyworded commands.
+ Also you can have incremental matching on commands or match after pressing return. (see sampleconfig for more info)
+ Also, copy paste works when typing commands:
+ * insert (paste X cliboard)
+ * shift insert (paste primary selection buffer)
+* FIFO & socket file: if enabled by setting their paths through one of the above means, you can have socket and fifo files available which are very useful to programatically control uzbl (from scripts etc).
The advantage of the fifo is you can write plaintxt commands to it, but it's half duplex only (uzbl cannot send a response to you).
The socket is full duplex but you need a socket-compatible wrapper such as netcat to work with it, or uzblctrl of course,
- an utitly we include with uzbl made especially for writing commnands to the socket (and at some point, it will be able to tell you the response too)
+ an utitly we include with uzbl made especially for writing commnands to the socket (and at some point, it will be able to tell you the response
+ too): `uzblctrl -s <socketfile> -c <command>`
+
+When uzbl forks a new instance (eg "open in new window") it will use the same commandline arguments (eg the same --config <file>), except --uri and--name.
+If you made changes to the configuration at runtime, these are not pased on to the child.
### COMMAND SYNTAX
-TODO
+Uzbl will read commands via standard input, named fifo pipe (if `fifo_dir` is set) and IPC socket (when `socket_dir` is set).
+For convenience, uzbl can also be instructed to read commands from a file on startup by using the `-c` option. Indeed, the config file is nothing more than a list of commands.
+
+Each command starts with the name of the command, which must be the first thing on a line; preceding whitespace is not allowed.
+A command is terminated by a newline. Empty lines and lines that start with the hash sign are ignored by the parser. Command names are always written in lowercase.
+
+The following commands are recognized:
+
+* `set <key> = <value>`
+ - used for changing variables on the fly
+ - the changes are effective immediately; for example, setting the variable `uri` will make uzbl start loading, and changing `status_format` will make the status bar react immediately
+ - if you want to unset a string, use `set` with one space after the equals sign
+* `get <key>`
+ - use this to print the value of a variable. (and TODO, get the value through the socket)
+* `bind <string> = <command>`
+ - sets the character sequence `<string>` to invoke `<command>` when typed interactively in uzbl
+ - there are a few tricks you can do:
+ * `<string>` ends with an underscore: the command will only be invoked after pressing return/enter. If the user enters text where `<string>` has the underscore, `%s` in the `<command>` string will be replaced by this text. (optional)
+ * `<string>` ends with an asterisk: similar behavior as with an underscore, but also makes the binding incremental (i.e. the command will be invoked on every keystroke).
+ * `<string>` ends on a different character: you need to type the full string, which will trigger the command immediately, without pressing enter/return.
+ - examples:
+
+ # uzbl will load the url when you type: 'o <url><enter>'
+ bind o _ = uri %s
+ # a search command which is called on every character typed after the slash, letting you see the search narrow down while typing.
+ # Hitting return, enter or esc will terminate the search.
+ bind /* = search %s
+ # when you type `ZZ` and nothing else, the exit command will be triggered immediately.
+ bind ZZ = exit
+
+* `back`
+* `forward`
+* `scroll_vert <amount>`
+* `scroll_horz <amount>`
+ - amount is given in pixels(?) or as a percentage of the size of the view
+ - set amount to 100% to scroll a whole page
+* `scroll_begin`
+* `scroll_end`
+* `reload`
+* `reload_ign_cache`
+* `stop`
+* `zoom_in`
+* `zoom_out`
+* `uri <address>`
+* `js <body>`
+ - execute the javascript in `<body>`
+ - remember that the commands must not contain line breaks
+* `script <file>`
+ - execute the javascript in `<file>`
+* `toggle_status`
+* `spawn <executable> <additonal args>`
+ - runs a command; see EXTERNAL SCRIPTS for details
+ - PATH is searched so giving the full path to commands is not neccessary
+ - note that the arguments as specified in "EXTERNAL SCRIPTS" are appended at the end, so the argument numbers will be higher.
+* `sh <command>`
+ - runs a shell command by expanding `%s` in the `shell_cmd` variable with the specified command; primarily useful as a shortcut for `spawn sh -c <body>`
+ - note that the arguments as specified in "EXTERNAL SCRIPTS" are appended at the end, so the argument numbers will be higher.
+* `sync_spawn <executable> <additional args>`
+* `sync_sh <command>`
+ - these are synchronous variants of `spawn` and `sh`, which means uzbl will wait for them to return
+ - you should only need to use these manually if you want to use a chain command in a handler that wants output from the command it runs
+* `exit`
+* `search <string>`
+* `search_reverse <string>`
+ - search with no string will search for the next/previous occurrence of the string previously searched for
+* `toggle_insert_mode <optional state>`
+ - if the optional state is 0, disable insert mode. If 1, enable insert mode.
+* `keycmd <string>`
+* `keycmd_nl <string>`
+ - keycmd sets the interactive command buffer to `<string>`. If the given string is a valid binding, it will execute. `Keycmd_nl` is like `keycmd`, but it also emulates a press of return, causing bindings with a parameter to execute. For example, `keycmd_nl o google.com` would load the said url if you have a binding like `bind o _ = uri %s`.
+* `keycmd_bs`
+ - erase (backspace) one character from the command buffer
+* `chain <command> <command> ..`
+ - use for chaining multiple commands
+ - remember to quote the commands; one command must come as one parameter
+ - if you use `chain` with a handler script which must return some output (such as a cookie handler -- uzbl will wait for and use its output), use sync_spawn or sync_sh instead of spawn or sh in the command that should give the output
+
### VARIABLE REPLACEMENT
Some of the variables are interpreted:
-* title bar: variable replacement (not yet actually)
+* title bar: variable replacement (long and short version, depending if statusbar is visible or not)
* user agent: variable replacement
* statusbar: variable replacement + pango markup
Have a look at the sample configs and scripts!
-Scripts that are called by uzbl are passed the following arguments:
+Handler scripts that are called by uzbl are passed the following arguments:
$1 uzbl-config-file
$2 uzbl-pid
$11 cookie (only with PUT requests)
+Custom, userdefined scripts (`spawn foo bar`) get first the arguments as specified in the config and then the above 7 are added at the end.
+
+### COMMAND LINE ARGUMENTS
+
+ -u, --uri=URI Uri to load (equivalent to 'set uri = URI')
+ -v, --verbose Whether to print all messages or just errors.
+ -n, --name=NAME Name of the current instance (defaults to Xorg window id)
+ -c, --config=FILE Config file (this is pretty much equivalent to uzbl < FILE )
+ --display=DISPLAY X display to use
+ --help Help
+
+
