Extracts and sorts software release numbers

Point separated, multi-point separated or semantic versioned and versioned suffixed

Use as standalone or embedded (~90 lines)

• Check GitHub Latest Release or Tag

floatversion -M "$(curl -sf "https://github.com/TuxVinyards/floatversion/releases" | grep 's/tag')"
1.0.0

floatversion -r "$(curl -sf https://github.com/qemu/qemu/tags | grep 's/tag')"
9.1.1  9.1.0  9.0.3  8.2.7  7.2.14  

floatversion -M "$(curl -sf https://github.com/qemu/qemu/tags | grep 's/tag')"
9.1.1

• Output as true/false test, as single item, or as space or line separated list.

• Filter for include, exclude, starts with, and reverse

  floatversion --options  "quoted-input-source"

  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 (unless -M)
  -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 highest/latest value in list, only, with '-r' shows lowest/earliest
  -g | --gt           A > B, returns true/false -g "A B" (.nums or sem ver, for -lt use B A)
  -v | --verbose      for problem output, show algorithm sequences (full version only) 
       --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' esp. with alpha suffixes
  All cases, returns false if none

Easy Install

FloatVersion will run in Bash or in Non-Bash shells.

Requires up-to-date versions of Bash, Grep and JQ. On MacOS install these via Homebrew.

Standalone

Copy to $PATH eg sudo cp floatversion /usr/bin or place the script in with your program.

Make sure that it has execute permissions sudo chmod +x /usr/bin/floatversion

The following simple wrapper can be used in Bash to call an includes folder full script:

ExampleProgFolder="/usr/share/my-prog/utils"
floatversion () { 
  "$ExampleProgFolder/floatversion" "$@" 
}

For Non-Bash, see below

Embedding

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.

The full version is named differently inside the standalone script to enable easy separation. When pasting the full version, it should be renamed to floatversion, the same as with the compact one.

Using the standard syntax floatversion --options "quoted-input-source" will ensure that if a function is not present, the call will re-route to floatversion as a standalone dependency, also that any later usage changes or any code re-use won't have negative impact.

Locale settings should be implemented as outlined in the floatversion script header.

Output Array

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.

Testing

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.

• Show verbose algorithmics

if floatversion --verbose --gt "$Current $LatestAchive"; then echo "Up to Date"; fi

Str:
12.7 12.6.0

Nums: (2)
12.7
12.6.0

declare -a NumArrTemp=([0]="12.7" [1]="12.6.0")

declare -a NumArrSorted=([0]="12.6.0" [1]="12.7")

declare -a fvOutputArr=([0]="12.6.0" [1]="12.7")

true

Updates

The script snippets, above, show how to check floatversion releases and how to compare versions.

Alternatively see GitHub's dependabot docs for setting up alerts ....

Use in different shells

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
1.10.3

To 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

Limitations

The input must resemble semantic versioning to some extent. The version number must be dot separated. Integers are ignored.

Some pre-filtering may be required.
