Article contents:== Outdated egg! This is an egg for CHICKEN 3, the unsupported old release. You're almost certainly looking for [[/eggref/4/fspath|the CHICKEN 4 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-4.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: eggs pathname]] [[toc:]] == FSPath - CommonLISP style Namestring and Pathname Object FSPath is an extension of unit utils {{pathname}} concept. The extended {{pathname}} is referred to as a {{namestring}}. The CommonLISP {{pathname}} object analog is the {{fs:pathname}} record object. ==== Namestring Four styles of {{namestring}} are supported: ; UNC : Universal Naming Convention, platform specific ; FIL : Filename, platform specific ; URI : Universal Resource Identifier ; FSS : Filesystem Specific (Unimplemented) ==== Record fs:pathname These {{namestring}} forms are mapped into {{fs:pathname}} components: ; host : host descriptor - hostname, IP address, domain name ; origin : drive, port, volume, device, logical name, environment variable ; directory : list of fs:filename representing directory components ; filename : fs:fIlename The {{fs:pathname}} record is to be a logical pathname, portable across platforms. Any missing component is represented by {{#f}}. A SRFI-10 reader and printer are supplied. ==== Record fs:filename These {{namestring}} forms are mapped into {{fs:filename}} components: ; base : string or symbol ; extensions : list-of string or symbol ; version : positive integer, symbol {{oldest}}, or symbol {{newest}} The {{fs:filename}} record is to be a logical filename, portable across platforms. Any missing component is represented by {{#f}}. A SRFI-10 reader and printer are supplied. ==== UNC Windows: \\<host>\<origin>\<directory>\<name>.<extension>[.<extension> ...]~<version>~ \\?\UNC\<host>\<origin>\<directory>\<name>.<extension>[.<extension> ...].~<version>~ Unix: //<host>/<origin>/<directory>/<name>.<extension>[.<extension> ...].~<version>~ <host>:/<origin>/<directory>/<name>.<extension>[.<extension> ...].~<version>~ ==== FIL Windows: <origin>:\<directory>\<name>.<extension>[.<extension> ...]~<version>~ \\?\<origin>:\<directory>\<name>.<extension>[.<extension> ...]~<version>~ Unix: /<directory>/<base>.<extension>[.<extension> ...]~<version>~ ==== FSS This form is filesystem specific. <specific> === Parameters ==== fs:default-unc-format [procedure] (fs:default-unc-format [FORM]) Gets or sets the behavior for converting a unc form to a namestring. Accepatble {{FORM}} is one of {{colon}}, {{slash}}, or {{uri}}. ==== fs:allow-empty-name [procedure] (fs:allow-empty-name [FLAG]) Gets or sets the behavior for an empty namestring, where {{#f}} means empty strings are ignored. === Pathname Procedures ==== fs:pathname?
