DIY (from sources)
This depends on:
- libboost-regex
- libboost-program-options
If you are on Debian/Ubuntu:
$ sudo apt-get install -y build-essential libboost-regex-dev libboost-program-options-dev
If you are on Mac OS X (using macports with libs installed in /opt/local):
$ sudo port install boost
Compile and install:
# download (or clone) the source
$ make
$ sudo make install
Usage
# Help and version info:
$ logcat-colorize
# Simplest usage:
$ adb logcat | logcat-colorize
# Using specific device, with time details, and filtering:
$ adb -s emulator-5556 logcat -v time System.err:V *:S | logcat-colorize
# Piping to grep for regex filtering (much better than adb filter):
$ adb logcat -v time | logcat-colorize | egrep -i '(sensor|wifi)'
# Save logcat output to file and read later with logcat colorize.
$ adb logcat > /tmp/logcat.txt
$ cat /tmp/logcat.txt | logcat-colorize
# List available formats, then set a specific format for debug messages.
# Set in your ~/.bash_profile to make it permanent.
$ logcat-colorize --list-ansi
$ export LOGCAT_COLORIZE_MSG_DEBUG="^[4;44;33m"
$ adb logcat | logcat-colorize
Note: I had written this as a quick approach in bash, but turns out it is pretty slow, specially pulling logcat from new devices (really a lot). So I decided to go a bit lower level and re-wrote this in C++. For reference, if you want to see the bash version, check out tag 0.2.0 (3f1486234a).
