File system and searching

Any file name in appletree will be handled by a function appletree.utils.get_file_path, which will search the file and return its path

appletree.utils.get_file_path(fname)[source]

Find the full path to the resource file.

Try 5 methods in the following order.

  • fname begin with ‘/’, return absolute path

  • url_base begin with ‘/’, return url_base + name

  • can get file from _get_abspath, return appletree internal file path

  • can be found in local installed ntauxfiles, return ntauxfiles absolute path

  • can be downloaded from MongoDB, download and return cached path

The last two methods are only used for XENON collabration. In most cases, method 1 and 2 are enough. And in method 2, the function will search the folders maps, data, parameters, configs.
