Documentation

A rather busy Semantic Versioning library.

Usage

(import semantic-version)

Core

Usage

(import (semantic-version core))

version-punctuation

[parameter] (version-punctuation [STR]) -> string

Returns the string (set) of punctuation characters. The first is always the default.

STR
string ; punctuation set, default is "._- +;:,".

make-version

[procedure] (make-version CNT [ELM CHR]) --> semantic-version

Returns new version with CNT elements, ELM, and punctuation CHR.

CNT
fixnum ; element count, from 0.
ELM
(or number string symbol) ; version element, default 0.
CHR
char ; version punctuation, default is (string-ref (version-punctuation) 0).

check-version

error-version

[procedure] (check-version LOC OBJ [NAM]) -> semantic-version
[procedure] (error-version LOC OBJ [NAM])

Similar to check-errors procedures.

version?

[procedure] (version? OBJ) --> boolean
OBJ
* ; object to test.

version->list

[procedure] (version->list VER) --> (list-of (or number string char))

Returns an "exploded" form, with version elements interleaved with punctuation characeters.

VER
semantic-version ; version to list.

list->version

[procedure] (list->version LIS) --> semantic-version

Returns a version from an "exploded" form, see version->list.

LIS
(list-of (or number string symbol char)) ; list of version components.

string->version

[procedure] (string->version STR) --> semantic-version

Return the parsed form of the STR. The source separator (punctuation) is preserved, and restored by version->string.

STR
string ; string to convert.

version->string

[procedure] (version->string VER) --> string

Return the string form of the VER.

VER
semantic-version ; version to convert.

Elements

Usage

(import (semantic-version element))

version

[procedure] (version ELM...) --> semantic-version

Returns a new version with the specified elements, ELM..., and the default punctuation (see version-punctuation).

ELM
(or number string symbol) ; version element.

Note that the symbol printname is used internally.

version-copy

[procedure] (version-copy VER) --> semantic-version

Return a copy of the version, sharing only atoms.

VER
semantic-version ; version to copy.

version-depth

[procedure] (version-depth VER) --> integer

Return the number of elements in the version.

VER
semantic-version ; version to query.

version-parts

[procedure] (version-parts VER) --> (list-of (or number string))

Returns list of version elements.

VER
semantic-version ; version to query.

version-puncs

[procedure] (version-puncs VER) --> (list-of char)

Returns list of punctuation characters.

VER
semantic-version ; version to query.

Comparisons

Usage

(import (semantic-version compare))

version-tail-zero

[parameter] (version-tail-zero [IGN?]) -> boolean

Returns whether trailing 0's are ignored during comparision.

IGN?
boolean ; ignore flag, default is #f.

version-compare

[procedure] (version-compare VER1 VER2 [TAIL-ZERO?]) --> integer

Returns a negative, zero, or positive integer representing the relative order of VER1 and VER2. Compares number & string elements natively, but in a comparison between a number & a string element, the string always takes precedence. Thus "1.a.2" < "a.1.2".

VER1
semantic-version ; version 1 to compare.
VER2
semantic-version ; version 2 to compare.
TAIL-ZERO?
boolean ; ignore trailing 0's?

Orders versions in the same manner as the chicken-install tool.

version<?

version=?

version>?

version<=?

version>=?

[procedure] (version<? VER1 VER2 [TAIL-ZERO?]) --> boolean
[procedure] (version=? VER1 VER2 [TAIL-ZERO?]) --> boolean
[procedure] (version>? VER1 VER2 [TAIL-ZERO?]) --> boolean
[procedure] (version<=? VER1 VER2 [TAIL-ZERO?]) --> boolean
[procedure] (version>=? VER1 VER2 [TAIL-ZERO?]) --> boolean

See version-compare.

version-strict=?

[procedure] (version-strict=? VER1 VER2 [TAIL-ZERO?]) --> boolean

Strictly equal, where VER1 & VER2 compare equal and have the same punctuation.

version-hash

[procedure] (version-hash VER [BND [RND]]) --> integer

A CHICKEN SRFI 69 hash function for the semantic-version type.

VER
semantic-version ; version to hash.
BND
integer ; bounds (limit), see SRFI 69.
RND
integer ; randomization (salt), see SRFI 69.

Operations

Usage

(import (semantic-version operation))

version-depth+

[procedure] (version-depth+ VER CNT [ELM CHR]) --> semantic-version

Returns a copy of VER with more "depth", as ELM, interspersed with CHR.

VER
semantic-version ; version to extend.
CNT
fixnum ; element count.
ELM
(or number string symbol) ; version element, default 0.
CHR
char ; version punctuation, default is (string-ref (version-punctuation) 0).

version-depth-

[procedure] (version-depth- VER CNT) --> semantic-version

Returns a copy of VER with less "depth", as CNT elements are dropped, along with the corresponding punctuation.

VER
semantic-version ; version to extend.
CNT
fixnum ; element count.

version-depth+!

[procedure] (version-depth+! VER CNT [ELM [CHR]]) -> semantic-version

Returns VER with more "depth", as ELM, interspersed with CHR.

VER
semantic-version ; version to extend.
CNT
fixnum ; element count.
ELM
(or number string symbol) ; version element, default 0.
CHR
char ; version punctuation, default is (string-ref (version-punctuation) 0).

version-depth-!

[procedure] (version-depth-! VER CNT) -> semantic-version

Returns VER with less "depth", as CNT elements are dropped, along with the corresponding punctuation.

VER
semantic-version ; version to extend.
CNT
fixnum ; element count.

version-extend

[procedure] (version-extend VER COMP...) --> semantic-version

Returns copy of VER with added "depth", in the form of a new "tail", in "exploded" form.

VER
semantic-version ; version to extend.
COMP
(list-of (or number string symbol char)) ; version components.

version-extend!

[procedure] (version-extend! VER COMP...) -> semantic-version

Returns VER with added "depth", in the form of a new "tail", in "exploded" form.

VER
semantic-version ; version to extend.
COMP
(list-of (or number string symbol char)) ; version components.

version-succ

[procedure] (version-succ VER [AMT [IDX [SEARCH?]]]) --> semantic-version

Return copy of VER with the target element at, or before with SEARCH?, IDX replaced by the AMT successor.

VER
semantic-version ; version to adjust.
AMT
fixnum ; amount to adjust, default is 1.
IDX
fixnum ; which element to adjust, default is (sub1 (version-depth VER)).
SEARCH?
boolean ; search backwards for a successful operation from IDX, default is #f.

Only integer elements may be targets. See Notes.

Underflow of a zero predecessor is an error. Overflow of a most-positive-fixnum successor is an error.

version-pred

[procedure] (version-pred VER [AMT [IDX [SEARCH?]]]) --> semantic-version

Return copy of VER with the target element at, or before with SEARCH?, IDX replaced by the AMT predecessor.

VER
semantic-version ; version to adjust.

Underflow of a zero predecessor is an error. Overflow of a most-positive-fixnum successor is an error.

version-succ!

[procedure] (version-succ! VER [AMT [IDX [SEARCH?]]]) -> semantic-version

Return VER with the target element at, or before with SEARCH?, IDX replaced by the AMT successor.

VER
semantic-version ; version to adjust.
AMT
fixnum ; amount to adjust, default is 1.
IDX
fixnum ; which element to adjust, default is (sub1 (version-depth VER)).
SEARCH?

Example

(import scheme utf8
  (chicken base)
  (chicken file)
  (chicken pathname)
  (chicken sort)
  semantic-version)

(define (filename->version fn)  (string->version fn))
(define (pathname->version pn)  (filename->version (pathname-strip-directory pn)))
(define (repo-tags repo egg)    (glob (make-pathname `(,repo ,egg "tags") "*")))
(define (egg-repo-versions repo egg) (map pathname->version (repo-tags repo egg)))

(for-each print (sort (egg-repo-versions REPO "apropos") version<?))
;=> prints release versions in ascending order
(string=? "a.1,b" ((o version->string string->version) "a.1,b"))
;=> #t
; but, assuming baseline `version-punctuation'
(string=? "a.1.b" (version->string (version 'a 1 'b)))
;=> #t
(define ver1 (version 'a 1 'b 2 "extra"))
ver1
;=> #<version "a.1.b.2.extra">
;See above for last element index as the default
(version-succ! ver1)
;=> #<version "a.1.b.3.extra">
;See Notes on indexing & element search
(version-pred! ver1 1 2)
;=> #<version "a.0.b.3.extra">
