logdog - a colorized Android logcat
Sometimes I do Android development. I never liked using debuggers, neither I use IDE. So my choice is to write Android apps with Vim+Terminal. With the lack of debugger I have to use logcat frequently, and using plain adb logcat (even with grepping output) is far from being pleasant.
Then I found there are nicer alternatives, like coloredlogcat or proclogcat. I tried them, but they lacked other output formats, like “time”. So I started writing my own one, which I successfully use in the last few months. It’s written in Python and seems to be the smallest logcat post-processor (it’s only about 100 LOC in a single file).
It supports “brief”, “time” and “raw” output formats and allows to filter output by one or several applications.
Here are some usage samples:
Show messages from phone app with timestamps:
$ logdog -v time com.andorid.phone
Show messages from app1 and app2:
$ logdog com.example.app1 com.example.app2
Show messages from all apps in raw format:
$ logdog -v raw
I also use bash/zsh snippets to autocomplete android process names:
#
# .zshrc
#
_logdog() {
local tag="${words[$CURRENT]}"
compadd $(adb shell ps | tr -d '\r' | awk -v tag=" $tag" '$0 ~ tag { print $9 }')
}
compdef _logdog logdog
#
# .bashrc
#
_logdog() {
local tag=${COMP_WORDS[COMP_CWORD]}
procs="$(adb shell pm list packages $tag | sed -e 's/package://')"
COMPREPLY=($(compgen -W "$procs" -- $tag))
}
complete -o default -o nospace -F _logdog logdog
And here’s how logdog looks in my terminal:
You can download logdog on the bitbucket page. Open source, MIT-licensed, as usual.
