Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

vercmp - version comparison utility
|
|
|
|
|
|
Synopsis
|
|
--------
|
|
'vercmp' [-h] [--help] <version1> <version2>
|
|
|
|
|
|
Description
|
|
-----------
|
|
'vercmp' is used to determine the relationship between two given version
|
|
numbers. It outputs values as follows:
|
|
|
|
* < 0 : if ver1 < ver2
|
|
* = 0 : if ver1 == ver2
|
|
* > 0 : if ver1 > ver2
|
|
|
|
Version comparison operates as follows:
|
|
|
|
Alphanumeric:
|
|
1.0a < 1.0b < 1.0beta < 1.0p < 1.0pre < 1.0rc < 1.0 < 1.0.a < 1.0.1
|
|
Numeric:
|
|
1 < 1.0 < 1.1 < 1.1.1 < 1.2 < 2.0 < 3.0.0
|
|
|
|
Additionally, version strings can have an 'epoch' value defined that will
|
|
overrule any version comparison, unless the epoch values are equal. This is
|
|
specified in an `epoch:version-rel` format. For example, `2:1.0-1` is always
|
|
greater than `1:3.6-1`.
|
|
|
|
Keep in mind that the 'pkgrel' is only compared if it is available on both
|
|
versions given to this tool. For example, comparing `1.5-1` and `1.5` will
|
|
yield 0; comparing `1.5-1` and `1.5-2` will yield < 0 as expected. This is
|
|
mainly for supporting versioned dependencies that do not include the 'pkgrel'.
