Hi all, I am going to apply the Google Summer of Code for the idea Machine readable output from userland utilities.Below is my proposal, opinions and suggestions are welcome. * Machine readable output from userland utilities * General Information ** Name Zhifeng ** Email szive@live.com ** Phone +86 188 2515 5746 ** Availability 40 hours per week ** Biography I'm an undergraduate student from department of computer science technology, Guangdong University of Technology, China. With years of study and practice I master some skills of C; and benefit from an online print project I get familiar with XML,JSON and libxml.I am a quick learner, and after having some research on the project I have a basic understand for the solution. Beside, since finished most of my course such as 'data structure','operating system' and 'computer network', I have enough time and willpower to overcome the difficulties during the project. ** Possible Mentor: * Project Information ** Project Title Easy parsed output from utilities ** Project Description To retrieval information from the output of utilities like sysctl,iostat is often a trivial work because of their design for human readable.In this project, I'd like to convert the utilities sysctl,ifconfig,vmstat,iostat and netstat to emit XML,JSON and YAML. My work will base on the library libbsdstat. After implemented, the library should understand the output structure of the utilities and can display statis- tics in XML, JSON and YAML format. For sysctl and ifconfig, it's not difficult to convert them;I would deal with the output of sysctl with options [-AadeioXx] and ifconfig with options [-mLaduvCk]. More attention will be pay on vmstat, iostat and netstat because they have dynamic statistics with option [-w [wait]]. I plan to set an environment variable to detect what format should be used. This reduce directly change in the utilities' sourcecode and may be useful in script programming. ** Deliverable 1) the utilities can emit XML format 2) the utilities can emit JSON format 3) the utilities can emit YAML format ** Test Plan + Check output of utilities with some special that are not convert is the same as before. + Check output of utilities can be proper parsed using libxml,libjson and libyaml. ** Project Schedule + before mid-term 1) 19 May to 4 June: sysctl and ifconfig can display XML output 2) 5 June to 25 June: iostat,vmstat and netstat can display XML output + mid-term to final-term 1) 26 June to 5 July: sysctl and ifconfig can display JSON output 2) 6 July to 20 July: iostat,vmstat and netstat can display JSON output 3) 21 July to 31 July: sysctl and ifconfig can display YAML output 4) 1 August to 18 August: iostat,vmstat and netstat can display YAML output Cheers, Zhifeng
