reV.config.base_config.BaseConfig

class BaseConfig(config, check_keys=True, perform_str_rep=True)

Bases: dict

Base class for configuration frameworks.

Parameters:

• config (str | dict) – File path to config json (str), serialized json object (str), or dictionary with pre-extracted config.

• check_keys (bool, optional) – Flag to check config keys against Class properties, by default True

• perform_str_rep (bool) – Flag to perform string replacement for REVDIR, TESTDATADIR, and ./

Methods

check_files(flist)	Make sure all files in the input file list exist.
check_overwrite_keys(primary_key, ...)	Check for overwrite keys and raise a ConfigError if present
clear()
copy()
fromkeys([value])	Create a new dictionary with keys from iterable and values set to value.
get(key[, default])	Return the value for key if key is in the dictionary, else default.
items()
keys()
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised
popitem()	Remove and return a (key, value) pair as a 2-tuple.
resolve_path(path)	Resolve a file path represented by the input string.
set_self_dict(dictlike)	Save a dict-like variable as object instance dictionary items.
setdefault(key[, default])	Insert key with a value of default if key is not in the dictionary.
str_replace_and_resolve(d, str_rep)	Perform a deep string replacement and path resolve in d.
update([E, ]**F)	If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
values()

Attributes

name	Get the job name, defaults to 'rev'.

REQUIREMENTS = ()

Required keys for config

STR_REP = {'REVDIR': '/home/runner/work/reV/reV/reV', 'TESTDATADIR': '/home/runner/work/reV/reV/tests/data'}

Mapping of config inputs (keys) to desired replacements (values) in addition to relative file paths as demarcated by ./ and ../

property config_dir

Get the directory that the config file is in.

Returns:

config_dir (str) – Directory path that the config file is in.

property config_keys

List of valid config keys

Returns:

list

property log_level

Get user-specified “log_level” (DEBUG, INFO, WARNING, etc…).

Returns:

log_level (int) – Python logging module level (integer format) corresponding to the config-specified log level string.

property name

Get the job name, defaults to ‘rev’.

Returns:

name (str) – reV job name.

check_overwrite_keys(primary_key, *overwrite_keys)

Check for overwrite keys and raise a ConfigError if present

Parameters:

• primary_key (str) – Primary key that overwrites overwrite_keys, used for error message

• overwrite_keys (str) – Key(s) to overwrite

static check_files(flist)

Make sure all files in the input file list exist.

Parameters:

flist (list) – List of files (with paths) to check existance of.

str_replace_and_resolve(d, str_rep)

Perform a deep string replacement and path resolve in d.

Parameters:

• d (dict) – Config dictionary potentially containing strings to replace and/or paths to resolve.

• str_rep (dict) – Replacement mapping where keys are strings to search for and values are the new values.

Returns:

d (dict) – Config dictionary with updated strings.

clear() → None.  Remove all items from D.

copy() → a shallow copy of D

fromkeys(value=None, /)

Create a new dictionary with keys from iterable and values set to value.

get(key, default=None, /)

Return the value for key if key is in the dictionary, else default.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised

popitem()

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

set_self_dict(dictlike)

Save a dict-like variable as object instance dictionary items.

Parameters:

dictlike (dict) – Python namespace object to set to this dictionary-emulating class.

setdefault(key, default=None, /)

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) → None.  Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D's values

resolve_path(path)

Resolve a file path represented by the input string.

This function resolves the input string if it resembles a path. Specifically, the string will be resolved if it starts with “./” or “..”, or it if it contains either “./” or “..” somewhere in the string body. Otherwise, the string is returned unchanged, so this function is safe to call on any string, even ones that do not resemble a path.

This method delegates the “resolving” logic to pathlib.Path.resolve(). This means the path is made absolute, symlinks are resolved, and “..” components are eliminated. If the path input starts with “./” or “..”, it is assumed to be w.r.t the config directory, not the run directory.

Parameters:

path (str) – Input file path.

Returns:

str – The resolved path.
