Lp-cli - Just Another Command Line Tool of Launchpad

The web interface of Launchpad is awesome, but it does not provide a function that you can save your search result, or even create a custom bug display list, I believe managers would like this function, especially they want to track each team member status.

I am just a engineer but also have almost the same requirement, here are 3 questions I need to answer in the end of weekend.

  • Which bugs I worked this week?
  • Which bugs I need to work next week?
  • Which bugs are waiting me to fix?

It is better to have a way to always show bugs I am interesting for different purpose, so I start to write a script by using python-launchpadlib.

by the way, another needs is to find bugs and modify attribute(s) of each bug.

python-launchpad

Launchpad has a very friendly python library, I will not talk this too much, if you want to know the details of it, please check these websites.

lp-cli

lp-cli include several tools which is very small and has only one trivial purpose, that is users can use Unix pipeline to combine small tools to archive a complex task.

All work of process data of Launchpad can be simplified as the following

  1. get data from Launchpad
  2. get sub set of data by some conditions
  3. do something on each entry one or multiple times
  4. do something on the final result such as save as a file or print to console

Use Case 1

Create a text file contains bugs I worked is modified this week.

$ lp-searchbugs people ossug-hychen  | \
  lp-view modified_thisweek | \
  lp-print buglist |  \
  lp-save bugs_modified_thisweek.txt
  • lp-searchbugs people ossug-hychen – find related bugtask of a user that login name is ossug-hychen
  • lp-view modified_thisweek – get bugs worked by ossug-hychen before and modified this week
  • lp-print buglist – then print the result in buglist style
  • lp-save bugs_worked_this_week.txt – then save the result as a file

the view modified_thisweek means the bug worked by anyone since 7 days before as defined here

data_getters:
...
        modified_thisweek:
                status: [Fix Committed,
                         Fix Released,
                         In Progress,
                         Incomplete (with response),
                         Incomplete (without response),
                         Triaged,
                         Invalid,
                         Won't Fix,
                         Confirmed]
                modified_since: $date_before_now
...

so if you want to know which bugs is really worked by yourself, we need another tool to limit the scope of result which is not done yet.

Use Case 2

reassign bugs I fixed in project ABC to another people, some time is QA

1
2

$ lp-searchbugs project ABC --status 'Fix Committed' --assignee ossug-hychen  | \
  lp-edit --assignee QA
  • first command is to get bugs fixed by me in project ABC
  • second command is to reassign each bugs to a QA guy

Available Commands

  • lp-searchbugs - type:Fetcher, generate a task of searching bugs in launchpad
  • lp-view - type:View, add extra args to received task (like lp-searchbugs)
  • lp-print - type:Task Action, execute received task and print the result
  • lp-save - type:Action, save STDIN to a file
  • lp-mybugs - shortcut of lp-searchbugs people $your-lp-login-id

because accessing Launchpad takes a lot of time, so the real data fetching work is only executed in Task Action command in my design.

[update]

Tim Chen told me a cool idea I never think about that you can save STDOUT of lp-searchbugs , lp-mybugs or lp-view to a text file

1

$ lp-mybugs | lp-view plan_nextweek > bugs_I_need_to_work_next_week.view

next time when you want to get the result, just type

1

$ lp-print buglist <  bugs_I_need_to_work_next_week.view

this behavior is similar what lp-view does, so now you can create any view you want!

Installation

$ add-apt-repository ppa:ossug-hychen/ppa
$ apt-get update
$ apt-get install lp-cli

Thanks

The idea of lp-cli is inspired by my friend Thinker Li’s image downloading tool
