在我的代码中我有
X_DEFAULT = ['a', 'long', 'list', 'of', 'values', 'that', 'is', 'really', 'ugly', 'to', 'see', 'over', 'and', 'over', 'again', 'every', 'time', 'it', 'is', 'referred', 'to', 'in', 'the', 'documentation']
以后
def some_function(..., x=X_DEFAULT, ...):
所以在我的Sphinx文档中,使用(例如,使用.. autofunction::
等),我在X_DEFAULT
的签名中扩展了some_function
的整个长而笨重的值:< / p>
some_function ( ...,x = ['a','long','list','of','values','that', '是','真的','丑','到','看','过','和','过','再次', '每个','时间','它','是','引用','到','在',''', '文档'],... )
是否有办法在生成的文档中禁止此替换,最好使用返回X_DEFAULT
定义的链接:
some_function ( ...,x = X_DEFAULT,... )
我知道我可以手动覆盖我明确列为Sphinx文档指令参数的每个函数和方法的签名,但这不是我的目标。我也知道我可以使用autodoc_docstring_signature
和docstring的第一行,但这会产生错误的文档字符串,真正用于内省失败的情况(如C)。我怀疑在autodoc-process-signature
中我可以做些什么可能足够(但并不完美),但我不确定如何继续。
答案 0 :(得分:0)
一种方法,例如,将“在模块级别定义的所有值”的“替换”替换为“公共常量”(由没有前导下划线的全部大写字母识别),其唯一名称可以可以在定义它的模块中找到:
def pretty_signature(app, what, name, obj, options, signature, return_annotation):
if what not in ('function', 'method', 'class'):
return
if signature is None:
return
import inspect
mod = inspect.getmodule(obj)
new_sig = signature
# Get all-caps names with no leading underscore
global_names = [name for name in dir(mod) if name.isupper() if name[0] != '_']
# Get only names of variables with distinct values
names_to_replace = [name for name in global_names
if [mod.__dict__[n] for n in global_names].count(mod.__dict__[name]) == 1]
# Substitute name for value in signature, including quotes in a string value
for var_name in names_to_replace:
var_value = mod.__dict__[var_name]
value_string = str(var_value) if type(var_value) is not str else "'{0}'".format(var_value)
new_sig = new_sig.replace(value_string, var_name)
return new_sig, return_annotation
def setup(app):
app.connect('autodoc-process-signature', pretty_signature)
另一种方法是直接从源代码中获取docstring:
import inspect
import re
def pretty_signature(app, what, name, obj, options, signature, return_annotation):
"""Prevent substitution of values for names in signatures by preserving source text."""
if what not in ('function', 'method', 'class') or signature is None:
return
new_sig = signature
if inspect.isfunction(obj) or inspect.isclass(obj) or inspect.ismethod(obj):
sig_obj = obj if not inspect.isclass(obj) else obj.__init__
sig_re = '\((self|cls)?,?\s*(.*?)\)\:'
new_sig = ' '.join(re.search(sig_re, inspect.getsource(sig_obj), re.S).group(2).replace('\n', '').split())
new_sig = '(' + new_sig + ')'
return new_sig, return_annotation
