.TH bollux.conf 5 2020-05-26
.SH NAME
.B bollux.conf
\- configuration file for
.BR bollux (1)
.SH DESCRIPTION
.BR bollux (1)
uses a number of environment variables that can be sourced from an external file,
usually placed in
.IR $XDG_CONFIG_HOME/bollux/bollux.conf .
The location can be changed at runtime by invoking
.BR "bollux \-c CONFIG" .
.SH VARIABLES
.SS Variables you might actually want to set
Here are actually useful variables that are good things to set in your
.IR bollux.conf ,
in order of usefulness.
.TP
.BR BOLLUX_URL " valid values are URLs; default is ''."
If
.B BOLLUX_URL
is set,
.BR bollux (1)
loads that resource;
otherwise it asks the user for where to go.
Setting this variable works like setting a home page.
.TP
.BR BOLLUX_DOWNDIR " valid values are directories; default is '.'."
The directory to attempt to save downloads in.
.BR bollux (1)
will attempt to download anything whose mimetype isn't
.IR text/* ,
and it tries to place it in
.BR BOLLUX_DOWNDIR .
If it can't open the directory, save the file,
or if there's another file with the same name,
.BR bollux (1)
will report the name of the temporary file it saved.
.TP
.BR BOLLUX_MAXREDIR " valid values are integers; default is '5'."
The maximum number of redirects before
.BR bollux (1)
decides to quit.
The default is 5 as per some RFC spec.
.TP
.BR BOLLUX_LOGLEVEL " valid values are '', DEBUG or QUIET; default is ''."
How verbose
.BR bollux (1)
should be.
.I DEBUG
prints debug-level messages.
.I QUIET
suppresses even error-level messages.
I'm going to be honest,
the difference between the levels is somewhat arbitrary.
So.
.SS Typesetting
.BR bollux (1)
typesets text/gemini content using the
.I typeset_gemini
function.
While it's probably possible to redefine the function in
.BR bollux.conf (5),
the default function is pretty nice (at least in my opinion).
The following variables control how text/gemini content is rendered:
.TP
.BR T_MARGIN " valid values are integers; default is 4."
The left margin for text.
Should be at least 3, since line-markers will be displayed in the left margin.
.TP
.BR T_WIDTH " valid values are integers; default is 0."
The total width of the window, including
.BR T_MARGIN .
If set to 0, attempts to use the width of the terminal,
falling back to 80.
.SS Colors
The different line-types in text/gemini documents are rendered with
.I m-class
terminal escapes (e.g., '\\e[31m').
The following variables should hold the values between
.I \\e[
and
.IR m ,
meaning valid values are anything between those that are valid terminal
color escapes.
.TP
.BR C_SIGIL " default: 35 (fg: magenta)"
The color of the line type as defined by text/gemini.
.TP
.BR C_LINK_NUMBER " default: 1 (bold)"
The color of the link number added by typeset_gemini.
.TP
.BR C_LINK_TITLE " default: 4 (underline)"
The color of the link's title, or if titleless, the URL.
.TP
.BR C_LINK_URL " default: 36 (fg: cyan)"
The color of the link's URL.
If the link doesn't have a title, this isn't used.
.TP
.BI C_HEADER "x where x is 1, 2, or 3"
The color of text/gemini headers.
The default for level 1 is
.IR 1;4 ,
for level 2 is
.IR 1 ,
for level 3 is
.IR 3 .
.TP
.BR C_LIST " default: 0 (no formatting)"
The color of list items.
.TP
.BR C_PRE " default: 0 (no formatting)"
The color of preformatted lines, as delimited by '```'.
.SS Variables that could be configured, but probably shouldn't be
These variables control deeper aspects of
.BR bollux (1)'s
workings.
It's possible they could be tweaked to make
.BR bollux (1)
work differently, like browsing gopher instead of gemini,
but that capability has not been tested.
.TP
.BR BOLLUX_PORT " valid values are port numbers (1-65535); default is '1965'."
The port
.BR bollux (1)
tries to connect to on the server.
.TP
.BR BOLLUX_PROTO " valid values are protocol names (strings); default is 'gemini'."
The protocol to use.
.TP
.BR BOLLUX_LESSKEY " valid values are files; default is '/tmp/bollux-lesskey'."
Where to store the generated
.BR lesskey (1)
file.
.TP
.BR BOLLUX_PAGESRC " valid values are files; default is '/tmp/bollux-src'."
Where to store the page source of the site being visited.
It's not used right now by
.BR bollux (1),
but you could ...
.BR cat (1)
it?
