Auto assign channel number

[wanderleyteixeira]

Hello. It would be nice to assign a starting channel number and increment it automatically for mapped channels.
The example below would auto increment the start_chno for each channel listed in that id. Also, if you redefine a chno in the attributes then subsequent channels will just increment or set something based on the group name.
Pattern Sport would start at 2000, Sport1 2001, New 3000, New1 3001, etc
Thoughts?

mappings:
  mapping:
    - id: CA-TV
      start_chno: '2000'
      mapper:
        - pattern: 'Name ~ "!start!.*Sport!quality!"'
          attributes:
            group: 'Sport'
            name: 'ABC |HD|'
        - pattern: 'Name ~ "!start!.*Sport1!quality!"'
          attributes:
            group: 'Sport'
            name: 'SSS |HD|'
        - pattern: 'Name ~ "!start!.*New!quality!"'
          attributes:
            group: 'News'
            name: 'XYZ |HD|'
            chno: 3000
        - pattern: 'Name ~ "!start!.*New1!quality!"'
          attributes:
            group: 'News'
            name: 'XYZ |HD|'

@wanderleyteixeira what I could imagine is that you enter a start number for a group and the channels are then numbered consecutively.
The problem is then to avoid overlapped channel numbers, if you dont give all groups a start number.

I need to think about this.

[wanderleyteixeira]

Yes, definitely something to consider. I'd still take the risk of overlaps rather than numbering 50+ channels. Thank you for taking into consideration. m3u-filter is great.

@wanderleyteixeira i have implemented a counter mechanism.

pushed to branch counter

Please can you test and confirm?

Each mapping can have a list of counter.

A counter has the following fields:

• filter: filter expression
• value: an initial start value
• field: title, name, chno
• modifier: assign, suffix, prefix
• concat: is optional and only used if suffix or prefix modifier given.

mapping:
  - id: simple
    match_as_ascii: true
    counter:
      - filter: '....some filter....'
        value: 9000
        field: chno
        modifier: assign
    mapper:
      - <Mapper definition>

you can also do something like this

mapping:
  - id: simple
    match_as_ascii: true
    counter:
      - filter: '....some filter....'
        value: 9000
        field: title
        modifier: suffix
        concat: " - "
    mapper:
      - <Mapper definition>

Let me figure out how to do it in a container. Will test soon and get back to you. Ty

[wanderleyteixeira]

I was just able to get to this though I do not see the branch anymore. Let me know.

[euzu]

@wanderleyteixeira the branch was merged to master.

[wanderleyteixeira]

Works great. Thank you!
