Sitemap filename changed in runtime.

[boxsnake]

Situation

In my situation, I am going to build a sitemap with following sub files:

• sitemap.xml <- Sitemap Index File
• sitemap/list-1.xml
• sitemap/list-2.xml
• ...,
• sitemap/list-n.xml
• sitemap/map-1.xml
• sitemap/map-2.xml
• ...
• sitemap/map-n.xml
  It has two groups: one starts with list- and one start with map-.

In this case, I set the Filename and then call *stm.Sitemap.Create() for each group.
However, the filename generator seems from *stm.Sitemap.Options.nmr, which is not reset when the filename is changed.

Hope to be fixed soon.

Code I am using

package main

import "github.com/ikeikeikeike/go-sitemap-generator/stm"

func main() {
    ... // Omit unimportant codes
    sm := stm.NewSitemap(0)
    sm.SetDefaultHost(conf.Sitemap.Host)
    sm.SetPublicPath(pubPath)
    sm.SetSitemapsPath("sitemap")
    sm.SetCompress(false)
    sm.SetPretty(conf.Sitemap.Pretty)
    sm.SetVerbose(conf.Sitemap.Verbose)

    // For `list-*`
    sm.SetFilename("list-")
    sm = sm.Create()
    for _, v := range list {
        sm.Add(...)
    }
    sm = sm.Finalize()

    // For `map-*`
    sm.SetFilename("map-")
    sm = sm.Create()
    for _, v := range list {
        sm.Add(...)
    }
    sm = sm.Finalize()
}

Expected to Get

In sitemap/:

• list-1.xml
• list-2.xml
• list-3.xml
• map-1.xml
• map-2.xml

Actual Got

In sitemap/:

• list-1.xml
• list-2.xml
• list-3.xml
• list-4.xml <- This seems created by namer in options, and the namer is not re-created when changing the filename
• list-5.xml

Proper solutions

1. Add a opt.nmr = nil at the end of *stm.Sitemap.SetFilename(), so that when calling *stm.Sitemap.Create() again, the namer will be recreated.
2. Add a *stm.Sitemap.SetNamer() to enable namer customizing.
