qi.path API

Introduction

qi.path is a set of functions to find binaries, libraries, data and configuration files on the system.

Reference

Libraries and binaries names

Some qi.path functions take the name of a library or a binary as a parameter.

Full name of the library means you will include the OS specific extensions in your name.

For example, libopencv_objdetect.so .

Just the name means that you can just have the simple name of the library you want,

and do not need to worry about its extension.

For example, opencv_objdetect .

Example

import qi
#where should I write the files for my application "myapp"?

dataPath = qi.path.userWritableDataPath("myapp", "mydatafile")
# datapath => /home/nao/.local/share/myapp/mydatafile
confPath = qi.path.userWritableConfPath("myapp", "myconffile")
# confPath => /home/nao/.config/myapp/myconffile


# I want to save all my data and configuration files in a personal folder
qi.path.setWritablePath("/home/nao/my_path")

dataPath = qi.path.userWritableDataPath("myapp", "mydatafile")
# datapath => /home/nao/my_path/data/myapp/mydatafile
confPath = qi.path.userWritableConfPath("myapp", "myconffile")
# confPath => /home/nao/my_path/config/myapp/myconffile
