Filter tags in LogCat (in Android Eclipse Plug-In)

Question

There is a TextField "Filter" below the LogCat output. However, it seems to filter only the Message-column. Id like to filter Tags also. Because there are my class names.

How can I achieve it?

Solution 1

There's a button that looks like a green + in the upper right of the log cat window, if you mouse over it says "Create Filter" in the popup from that you can filter by log tag. It creates a new tab in log cat with the filter name you specified. Then all of the output of that tag will go to that tab and not the "Log" tab.

Solution 2

In Eclipse, if I would like to exclude those annoying Choreographer messages,I write this filter in the logcat filter TextField : tag:^(?!Choreographer).*$ and it excludes all messages which tag starts with the text Choreographer

If you want multiple exclusions : tag:^(?!Choreographer|dalvikvm-heap|Trace).*$

Solution 3

The Log tag field accepts Java regular expressions, so try this:

^TAG_A$|^TAG_B$

which matches exactly those tags. You can go crazy with complicated regular expressions, if that's your idea of fun.

Solution 4

Old question, but still relevant, and didn't see this answer among the answers here.

To filter by multiple columns in logcat textfield, simply use a space between regular expressions, and the column title in lower case followed by : to assign the regex to that column instead of the default "text:"

for example:

tag:wif text:event

a space '' is used as an AND argument.
a single '|' without space is an OR.

Regarding one of the comments I've seen here - There is no realy need for a wildcard, since it is automatically applied before and after the filter text.
If you don't want wildcard, you can use regular expression syntax to restrict the string.
for example: ^starswith or fullword$

TIP: if you want to match a space character or a tab in your output, just type in: \s at the desired place.

Solution 5

When filtering, you must use no whitespace after 'tag:' and all is case sensitive. For example:

tag:MIRKO

and not

TAG: mirko

Can't use wildcards like "com.mynamespace.*" ;( But thanks for showing me that function ;)

Could you provide the commands how to pipe it in the shell? Sorry, I grew up with OS using GUI and have no clue on those things...

[Chris Stratton]

adb logcat | grep someNameOfInterest you can also use the -i flag to make it case insensitive. Oh, and you have to have grep, ie, be on linux or unix or cygwin or msys or have a grep executable for your OS.

I'd really like to be able to use wildcards in here too.

Woah great, I never noticed that. Welcome to StackOverflow!

This seems to be working only in ADT, since if I use it programatically (Runtime.getRuntime().exec("logcat [<option>] ... [<filter-spec>] ...")), it doesn't work.

thanks for the tip with the whitespace \s that is exactly what I was looking for
