Read & write INI configuration files.
ini-file is a small library for reading & writing INI files, such as those used in early Windows configuration scripts.
INI syntax as a whole is underspecified and its implementations vary. This egg supports only its most basic features (comments, sections, zero- and one-valued properties).
The source for this egg is available at http://github.com/evhan/ini-file.
API[procedure] (read-property [port])
Reads a single INI property from port. If it is a section header, returns a symbol. If it is a property or property/value pair, a pair is returned. Invalid properties will signal an error.
Numeric values and quoted strings are read as such; everything else is treated as a string literal.[procedure] (read-ini [file-or-port])
Reads configuration directives from file-or-port until #!eof, returning an alist of alists corresponding hierarchically to the source INI's SECTION -> PROPERTY -> VALUE structure.
Properties appearing before any section heading are associated with the key given by the default-section parameter.
If file-or-port is a port, it is not closed.[procedure] (write-ini alist [file-or-port])
Writes alist as INI directives to file-or-port.
A symbol at the head of alist signifies a section of that name. The write order of alist's properties is reverse that of alist.
The property-separator parameter specifies the character or string with which to separate property names & values.
If file-or-port is a port, it is not closed.
Parameters[parameter] (default-section [name])
Specifies the default alist key (usually a symbol) under which properties without a section label will be placed read-ini. Defaults to 'default.[parameter] (property-separator [char-or-string])
Specifies the character or string to be used by write-ini to separate property names & values. Defaults to #\=.[parameter] (allow-empty-values? [boolean])
Specifies whether the empty string should be treated as a valid property value. If #f, an empty value will signal an error. Defaults to #f.[parameter] (allow-bare-properties? [boolean])
Specifies whether "bare" properties (those without a value) should be allowed. If #f, a line not following "key separator value" format will signal an error. Defaults to #t, making the default parsing behavior very forgiving.
Git uses INI syntax for its configuration files. From man git-config:
# # This is the config file, and # a '#' or ';' character indicates # a comment # ; core variables [core] ; Don't trust file modes filemode = false ; Our diff algorithm [diff] external = /usr/local/bin/diff-wrapper renames = true ; Proxy settings [core] gitproxy="proxy-command" for kernel.org gitproxy=default-proxy ; for all the rest
(use ini-file) (read-ini ".git/config") ; => ((core (gitproxy . "default-proxy") ; (gitproxy . "\"proxy-command\" for kernel.org")) ; (diff (renames . "true") ; (external . "/usr/local/bin/diff-wrapper")) ; (core (filemode . "false")))
Note that separate sections of the same name are not merged.
