the module wants me to choose the format and gives me a list of names, but... what are they?

[DinoChiesa]

Is there a definition of the formats of "Log4j" and "PHP" and "Monolog" and "Log4j2", and all the rest? Or a set of samples showing what these names actually mean?

Logview wants me to choose a format by name, but I don't know what the names mean. And I don't see examples of those formats in the documentation. I guess if I am a PHP log expert I would know what PHP logs look like. But I'm not. Nor do I know any of the other formats.

I know the format I'm looking at in the log file that interests me right now. But I don't know if that format has a name. EDIT - I believe it is called NDJSON - each log entry is a JSON hash.

{"level":"info","ts":1763678751.80141,"caller":"cmd/main.go:664","msg":"starting filesystem cleanup controller"}

How do I connect the dots here?

It asks me for a timestamp format and I'm seeing a list of choices, but mine isn't in there. My timestamp format is epoch seconds and microseconds. ssssssssss.SSSSSS . But I couldn't specify that.

??
am I holding it wrong?

Is there a sample for defining a NEW submode? My own? I read the doc and comments but couldn't figure it out. If it's a regex I need to supply for each field (level, message, timestamp, source, name, etc), I can do that. But how?

Standard formats are defined in three variables `logview-std-...` near the top of `logview.el`. User-custom additions should go into the corresponding three variables named `logview-additional-...` in the same format. If you have a nonstandard timestamp (usually they include full time, not just seconds like in your case), you should add an entry to `logview-additional-timestamp-formats`.

The timestamp format isn't quite the whole answer here.

Is there a sample for defining a NEW submode? I read the doc and comments in the code, but couldn't figure it out. If it's a regex I need to supply for each field (level, message, timestamp, source, name, etc), I can do that. But how?

Maybe I'll ask an AI coding assistant to tell me.

From documentation of `logview-additional-submodes`: The only mandatory and the most important field that defines how log entries are built from pieces. There are currently four such supported pieces: \"TIMESTAMP\", \"LEVEL\", \"NAME\" and \"THREAD\". All four are optional. For example, Log4j, by default formats entries according to this pattern: TIMESTAMP [THREAD] LEVEL NAME - Definition of `logview-std-submodes`: '(("SLF4J" . ((format . "TIMESTAMP [THREAD] LEVEL NAME -") (levels . "SLF4J") (aliases . ("Log4j" "Log4j2" "Logback")))) ...

Thanks

I guess the idea in logview is that the various fields are well ordered.
That won't apply in ndjson - the fields are labeled but not necessarily ordered.
I'm still looking through this.
