lcdproc-config man page

The syntax for LCDproc's configuration files is INI-file style.

They are 8-bit text files divided into sections, each containing zero or more key-value pairs. Sections are introduced by section labels which start with '[' and end with ']', and key-value pairs consist of a key name, a '=' sign and a value each.

Key names are sequences of non-space characters, not starting with '[' and not containing '=' or '\n', while values are shell like strings. I.e. they are either simple sequences of non-space characters, or double quoted-strings with C-style syntax (except the missing support for '\NNN' and '\xNN' escape sequences) or or a mix of both of these forms.

Section labels and key names are case-insensitive and may occur more than once. Keys of duplicate sections will be merged into one section, while the values of duplicate keys in a section will be appended to form an array of values for this key. (In the program, all values of a key can be retrieved individually)

Spaces around section labels, keys, and values are ignored. Lines starting with ';' or '#' are considered comments and ignored too.

While all of the above is quite common to almost all INI-file implementations, there are a few special features that make LCDproc's config files special:

• Section labels may contain any character except ']', '\n' or '\0'. However, all characters are interpreted literally (i.e. neither quoting, nor escaping done).
• Key names may contain any non-space character except '\n' or '\0'. However, all characters are interpreted literally (i.e. neither quoting, nor escaping done).
• Comments are allowed after section labels and key value pairs
• Values may be a mix of quoted and unquoted strings similar as strings are interpreted in the shell. E.g. the value 'string" with "blanks"\t!"' will be parsed as 'string with blanks<TAB>!' where <TAB> stands for the TAB character.

In case of a a parsing error the rest of the line is ignored and parsing continues with the next line.

The section '[lcdproc]' defines the options to connect to the LCDd server : hostname, port, log level...

Server=

address of the LCDd server to connect to

Port=

Port of the server to connect to

ReportLevel=

set reporting level

ReportToSyslog=

DisplayName=

display name for the main menu [default: LCDproc HOST]

the following section of the /etc/lcdproc/lcdproc.conf contains screen specific configuration options. Each section refers to a screen which can be enabled and configured.
