Add replace for regexp, allow regexp and replace for jsonpaths

[se35710]

Allows for more dynamic version extractions, eg when jsonpath doesn't exactly match the version, or when you want to rearrange the regexp matches for a better version string.

I've changed so now both jp and re are allowed at the same time. jp is executed first, and then re is applied on the jsonpath. If replace is defined, it is applied on the regexp match.

Examples:

    "checkver": {
        "url": "https://superduper.io/versions.json",
        "jp": "$..name",
        "re": "(?<version>[\\d.]+)",
        "replace": "2.${version}"
    },

Cool 👍
Do you have an example of the replace thing? Does it result in 2.1.0 if the regex matched 1.0?

superduper.io 😁

Yes, and it works with mutiple matching groups too, so "${1}-${date}" would create a version string of "0.0.1-19620102".

The example above was with jsonpath, but this would work too.

    "checkver": {
        "url": "https://superduper.io/versions.html",
        "re": "(?<date>[\\d]+)\\sdupes-([\\d.]+)",
        "replace": "${1}-${date}"
    },

When checkver is only a string (see 7zip, wget) then $replace would be the replace() function from System.String. 😁

@nightroman does this work fine on your end?

It sounds good and I have use cases for this feature. I am on holiday, will try only in a week or two.

It seems to be working for me with a manifest like

{
    "url":  "https://download.sysinternals.com/files/SysinternalsSuite.zip",
    "version":  "June.14.2017",
    "env_set":  {
                    "SysinternalsSuite":  "$dir"
                },
    "homepage":  "https://technet.microsoft.com/en-us/sysinternals/bb842062.aspx",
    "checkver":  {
                     "re":  "\\bUpdated:\\s*(\\w+)\\s+(\\d+),\\s+(\\d+)\\b",
                     "replace":  "${1}.${2}.${3}"
                 }
}
