Trying to use thread placeholder on Rolling File writer

[joao-ribeiro83]

I'm trying to use the following tinylog.properties with tinylog 2.6.1:

rolling file

writer = rolling file
writer.level = trace
writer.format = {date: HH:mm:ss.SSS}|{thread}|{class}-{method}:{line}-{level}: {message}
writer.file = logs/{date:yyyy}/{date:MM}/log_{date:yyyy-MM-dd}{thread}{count}.log
writer.latest = logs/latest_{thread}.log
writer.charset = UTF-8
writer.buffered = true
writer.policies = startup, daily: 00:00, size: 2mb
writer.convert = gzip
writingthread = true

But i'm getting the following error when ever I use thread placeholder on writer.file or/and writer.latest:

LOGGER ERROR: Failed creating service implementation 'org.tinylog.writers.RollingFileWriter' (java.lang.IllegalArgumentException: Invalid token 'thread' in 'logs{date:yyyy}{date:MM}\log_{date:yyyy-MM-dd}{pid}{thread}_{count}.log')

Is it a bug or I'm doing something wrong? I'm trying to do rolling file per thread.

This is a feature request. There is no thread placeholder for file paths.

Currently supported placeholders for file paths:
https://tinylog.org/v2/configuration/#rolling-file-writer

I thought any placeholder was possible in any case!
Maybe on the documentation is better to specify what placeholders are possible in each writer type and method.

For my request, yes its a feature for debugging if the application has several identical threads to identify the thread whith the problem.

We have placeholder for log messages that can be used by every writer for formatting its log messages: https://tinylog.org/v2/configuration/#format-pattern

On the other hand, we have placeholder for file paths that can only be used by the rolling file writer: https://tinylog.org/v2/configuration/#rolling-file-writer

Ideas how to document the differences are welcome :)
