This manpage contains additional hints and pointers regarding its usage.
.\" --------------------------------------------------------------------

.P
.SS "Main window \(em location bar focused"
.TP
\fBEscape\fP
Reset the content of the location bar to the current URI.
.TP
\fBReturn\fP
Commit, i.e. begin searching, do a keyword based search or open the URI.
.P
.SS "Download manager"
.TP
\fBMod1\fP + \fBd\fP
.TQ
\fBMod1\fP + \fBq\fP
Close the download manager. Active downloads are never aborted. However,
if there are no more active downloads and no more browsing windows, then
the entire program will quit.
.\" --------------------------------------------------------------------
.SH "DOWNLOAD MANAGER"
Open the download manager using the appropriate hotkey. A new window
listing your downloads will appear. Clicking on an item will remove it
from the list and \(em if needed \(em cancel the download.
.P
There's no file manager integration, nor does \fBlariza\fP delete,
overwrite or resume downloads. If a file already exists, it won't be
touched. Instead, the new file name will have a suffix such as \fB.1\fP,
\fB.2\fP, \fB.3\fP, and so on.
.\" --------------------------------------------------------------------
.SH "KEYWORD BASED SEARCHING"
In this file, you can configure keywords and the associated URIs:
\fI~/.config\:/lariza\:/keywordsearch\fP. Each line has to look like
this:
.P
\f(CW
.nf
\&wi https://en.wikipedia.org/w/index.php?title=Special:Search&search=%s
.fi
\fP
.P
\fBwi\fP is the keyword, so when opening \fBwi foo\fP, \fBlariza\fP
will search in Wikipedia. Note the \fB%s\fP at the end of the URI: This
is where your search term will be placed.
.P
Lines starting with \fB#\fP are ignored.
.\" --------------------------------------------------------------------
.SH "USER-SUPPLIED JAVASCRIPT FILES"
After a page has been successfully loaded, the directory
\fI~/.config\:/lariza\:/user-scripts\fP will be scanned and each file in
it ending with \fB.js\fP will be run as a JavaScript file in the context
of said page.
.P
During development, you will most likely want to run \fBlariza\fP with
$\fBLARIZA_ENABLE_CONSOLE_TO_STDOUT\fP enabled.
.P
\fBlariza\fP comes with the following scripts:
.TP
\fBhints.js\fP
Press \fBf\fP (open link in current window) or \fBF\fP (open in new
window) to activate link hints. After typing the characters for one of
them, press \fBEnter\fP to confirm. Press \fBEscape\fP to abort.
.P
Those bundled scripts are automatically installed on \fBmake install\fP.
To use them, though, make sure to link them to the directory mentioned
above.
.\" --------------------------------------------------------------------
.SH "WEB EXTENSIONS"
On startup, WebKit checks \fI~/.config/lariza/web_extensions\fP for any
\fB.so\fP files. See
.UR http://\:blogs.igalia.com/\:carlosgc/\:2013/\:09/\:10/\:webkit2gtk-\:web-\:process-\:extensions/
this blog post
.UE
for further information on these extensions.
.P
\fBlariza\fP comes with the following extensions:
.TP
\fBwe_adblock.so\fP
Generic adblock. Reads patterns from the file
\fI~/.config/lariza/adblock.black\fP. Each line can contain a regular
expression. These expressions match case-insensitive and partially, i.e.
\fB.*foo.*\fP is the same as \fB.*FOO.*\fP and you can use anchors like
\fB^https?://...\fP. Please refer to
.UR https://\:developer.\:gnome.\:org/\:glib/\:stable/\:glib-\:regex-\:syntax.html
the GLib reference
.UE
for more details. Lines starting with \fB#\fP are ignored.
.P
Those bundled web extensions are automatically compiled when you run
\fBmake\fP and installed on \fBmake install\fP. To use them, though,
make sure to link them to the directory mentioned above.
.\" --------------------------------------------------------------------
.SH "EXTERNAL URI HANDLER"
\fBlariza\fP can launch an executable called
\fIlariza-external-handler\fP. It will be passed the \(lqselected\(rq
URI as a command line argument:
.P
\f(CW
.nf
$ lariza-external-handler -u https://github.com
.fi
\fP
.P
This executable must be a user-supplied program. It can do anything it
wants to with that URI. \fBlariza\fP ignores the exit code of the
handler.
.P
The \fB\-u\fP will always be set. This allows you to use \fBgetopt\fP(1)
like parameter parsing in your program.
.P
You can either use the appropriate hotkey (see list above) to launch the
handler with the currently loaded URI, or you can perform a right click
on any link, image or media file to use that URI.
.P
This mechanism allows you to implement a variety of functions. You might
want to implement a bookmarking script or a password manager or you
might simply load the current URI in a different browser. That's up to
you.
.\" --------------------------------------------------------------------
.SH "TRUSTED CERTIFICATES"
By default, \fBlariza\fP trusts whatever CAs are trusted by WebKit, i.e.
by your GnuTLS installation. If you wish to trust additional
certificates, such as self-signed certificates, the first thing you
should do is try to add the appropriate CAs to your system-wide store.
.P
If you wish to add simple exceptions, you can grab the certificate and
store it in the directory \fI~/.config/lariza/certs\fP. The filename
must be equal to the hostname:
.P
\f(CW
.nf
\&$ echo | openssl s_client -connect foo.de:443 | openssl x509 >foo.de
.fi
\fP
.P
This tells \fBlariza\fP to trust the given certificate when connecting
to host \fBfoo.de\fP.
.P
You can reload these certificates at runtime by pressing the appropriate
hotkey. Note that removed certificates will be kept in memory until you
restart \fBlariza\fP.
.P
Note: This is NOT equal to certificate pinning. WebKit ignores
user-specified certificates if the server's certificate can be validated
by any system-wide CA.
.\" --------------------------------------------------------------------
.SH "WEBKIT LOCAL STORAGE"
WebKit does create files in your $\fBXDG_*\fP directories, i.e.
\fI~/.local/share\fP or \fI~/.cache\fP. It's up to you what you want to
do with this junk. I remove it regularly when no WebKit browser is
running. Another option would be to change the $\fBXDG_*\fP variables.
.P
I have explicitly not turned off the local storage feature in WebKit
because I don't know if this breaks web applications.
