Point separated, multi-point separated or semantic versioned and version-suffixed
Use as full standalone, or compact embedded (~110 lines)
DeepWiki:
The floatversion system is designed as a robust version extraction and comparison pipeline .... The architecture prioritizes high-precision sorting of semantic versions (SemVer) ... from strings, files, or pipes ... The core strength of the architecture is its sorting flexibility. It defaults to a sophisticated jq filter that understands SemVer precedence, but can fall back to sort -V (version sort) or sort -n (numeric sort) for simple floating-point numbers.

9.2.3 9.2.2 9.2.1- Multiple Filters: include, exclude, starts with, reverse ...
floatversion --options "quoted-input-source-or-data" (all options and values space separated)
OR piped stdout, | floatversion --options "optional-additional"
Extracts point separated numbers, or semantic version numbers with optional suffixes,
and other common variations upon, from a given string or text-file
-h | --help show help
-V | --version show version
-c | --col show list as column instead of string (-qc quieter errors)
-s | --space use single spaced string for machine reading (-qs quieter errors)
-r | --rev show list in reverse order
-a | --all show all extracted values, not just unique
-n | --num sort by standard numbering, not versioning
-f | --full check for additional sem. ver. suffixes, eg. -beta
-F | --filter contains given items -F "string string string"
-S | --starts starting with -S "string string string"
-D | --delete doesn't contain: -D "string string string"
-M | --max Outputs the single highest/latest value in the list and with '-r' the lowest/earliest,
with integer shows top or bottom of total list eg. -M 3 is top 3 and -M 3 -r the bottom.
-RM [int] Outputs the single lowest/earliest value in the list.
With integer, as -M but NB reverses only the M filter set, not the whole input list
eg. fv -RM 2 "4.2 3.1 2.5 1.7" > 3.1 4.2
-R [int] Outputs the lowest/earliest values in the list (use -r to reverse output order)
eg. fv -r -R 2 "4.2 3.1 2.5 1.7" > 1.7 2.5
-g | -qg | --gt A > B, returns true/false eg. if fv -g "A B"; then .. (.nums or sem-ver, implies -f)
use -v for dev output, normally quiet and allows conditional testing
Pre-sanitize input where possible. Use -qg to quieten the internal santizer's error output.
-Q | --quiet Quieten general error messages, as alternative to using '2>/dev/null'
Use -qc | -qs | -qg for reduced error output on full machine tests (no help notes)
-v | --verbose Show algorithm sequences (full version only) for problem output
--sort-v use sort -V (if present) in preference to the default jq methods
--no-svb no falling back to 'jq' if 'sort -V' is unavailable, show error instead
Without options, produces a single sorted string of all unique items found
Filters output as string, column or max. Post-output grep requires columns.
Tests show 'jq' sort methods as more reliable than 'sort -V' when encountering suffixes
In all cases, returns false if none found in data, with error if data missing.
Stdin and Pipes require the Standalone version. Either or both input methods may be used.
Only use 'fv' or short name links in PATH controlled situations. See readme for further notes.

Up to DateFloatVersion will run in Bash or in Non-Bash shells.
Requires up-to-date versions of Bash, Grep, JQ, BC and Curl.
- On MacOS install these via Homebrew
Curl is needed from version 1.1 for the update checker on the full version only.
BC is needed for standard numerical comparisons.
Also see DeepWiki deployment notes:
The name floatversion was carefully checked for duplication before it was selected.
Short forms, such as fv may be used but only in controlled situations.
From version 1.3 onwards, sub-shelled pipe constructs are possible when the full version script has been located within $PATH
Ideally the script should be placed in a non-standard location and a temporary session export routine should be used:
fvPath="/usr/share/my-prog/utils"
export PATH="${fvPath}:${PATH}"This method is ideal when re-using script lines that have been employed on the embedded floatversion function.
It is slightly easier to set up but code lines are slightly longer to construct.
A simple wrapper can be used in Bash to call the full script from an includes folder:
floatversion () {
"/usr/share/my-prog/utils/floatversion" "$@"
}For Non-Bash, see below
Using these methods enables shorthand fv commands to go directly to the full version instead of the compact:
Where a custom PATH has been exported within a script, or where a custom path is head of the PATH list
cd /usr/share/my-prog
sudo ln -s floatversion fv
>
fv -f -S "1.2" "non-pad-test.txt" etc ...On a known computer where local or other appears first in $PATH and where the addition of other software is user controlled
# possibly:
sudo cp floatversion /usr/local/bin
sudo chmod +x /usr/local/bin/floatversion
alias fv='floatversion'
>
ls | fv -f
5.13 6.8.0-56-generic 6.8.0-57-genericFor working examples of PATH control and use of shorthanding fv links, see the qqX project and the included qqX file path.notes.for.floatversion.deployment.md
This method is suitable only for Bash scripts:
Single scripts can add the compact function in a simple copy and paste operation which is ready to go
In larger projects, the required extra space for the full function won't notice and you will have verbose mode ready built in
Either of the functions can be copied by simply opening the floatversion script in a text editor
With release 1.6.01 the full function is named as 'floatversion' which enables keeping the compact, compactly named as 'fv' to run alongside, and to avoid problems with self-recursive calls
The newer defaults also mean that calls scripted either as 'fv' or as 'floatversion' will now both work and that if embedding just the compact version, this may be renamed as floatversion, as required, without problems
Having a standard command format of fv | floatversion --options "quoted-input-source" ensures that any code call will auto-route to floatversion as a standalone dependency if later switching to this method, or if later switching to compact, or if wanting to re-use code elsewhere.
Locale settings should be implemented as outlined in the floatversion script header
The standalone script can be set to output a transfer file which is easily mappable by most shells. When embedding, the array ${fvOutputArr[*]} is by default present as global. See notes at start of script
For testing the compact function inside scripts, it is recommended that a $PATH version be installed on the development computer. Any Bash script calls can then be temporarily prefixed by the control word command which will cause the function to re-route and will allow verbose output to be enabled

Error message suppression may be used to tidy screen output, if required. This can be particularly useful when producing machine output.
The script snippets, above, show how to check floatversion releases and how to compare versions.
Version 1.1 now has an auto-update checker that will run on request:
floatversion -V
CurrentVersion: 1.1.0
Checking for updates.... LatestVersion: 1.1.0 Up-to-Date
(c) Alex Genovese https://github.com/Alex-Genovese/floatversion
OR ....
if floatversion -V | grep -sq 'Up-to-Date' ; then echo OK ; fi
OKRequires Curl. @ 2024 Most distros will have this.
Alternatively see GitHub's dependabot docs for setting up alerts ....
The script's Shebang will mean that direct running of the standalone is possible from the interactive terminal.
For example:
╭─xxx@garuda in repo: floatversion on main [$]
╰─λ echo $SHELL
/usr/bin/fish
╭─xxx@garuda in repo: floatversion on main [$]
╰─λ floatversion -F 10 -M -n "non-pad-test.txt"
1.10.3To include calls to floatversion standalone script from within an actual fishshell script, the following method may be used:
╭─xxx@garuda in repo: floatversion on main [$] took 0s
╰─λ if bash -c 'floatversion --gt "1.4.5 2.3.6.7"'
echo yes
else
echo no
end
no
╭─xxx@garuda in repo: floatversion on main [$] took 0s
╰─λ if bash -c 'floatversion --gt "3.4.5 2.3.6.7"'
echo yes
else
echo no
end
yes
The use of a transfer file will enable variables to be passed:
╭─xxx@garuda in repo: floatversion on main [$]
╰─λ set Foo 3.1.4.1
╭─xxx@garuda in repo: floatversion on main [$]
╰─λ set Bar 42.00
╭─xxx@garuda in repo: floatversion on main [$]
╰─λ if bash -c 'floatversion --gt "$Foo $Bar"'
echo yes
else
echo no
end
ERROR: no input found.
# Output vars to file and read file instead:
╭─xxx@garuda in repo: floatversion on main [$?] took 0s
╰─λ echo "$Bar $Foo" > fish-tx.txt
╭─xxx@garuda in repo: floatversion on main [$?] took 0s
╰─λ if bash -c 'floatversion --gt "fish-tx.txt"'
echo yes
else
echo no
end
yes
The input must resemble semantic versioning to some extent, or decimal floating points.
-
Plain integers are ignored. The version number must be dot separated.
-
Only one single hyphenated suffix is permitted.
Some pre-filtering may sometimes be required.
If the version number is embedded amongst multi-hyphens, then full hyphen removal may help.
