[英]Pdf-latex with python script, custom python variables into latex output
[英]Changing style of PDF-Latex output through IPython Notebook conversion
目前使用我的.ipynb文件的以下命令:
$ ipython nbconvert --to latex --post PDF Untitled1.ipynb --SphinxTransformer.author="John Doe"
[NbConvertApp] Using existing profile dir: u'/Users/me-macmini/.ipython/profile_default'
[NbConvertApp] Converting notebook Untitled1.ipynb to latex
[NbConvertApp] Support files will be in Untitled1_files/
[NbConvertApp] Loaded template article.tplx
[NbConvertApp] Writing 12876 bytes to Untitled1.tex
[NbConvertApp] Building PDF
[NbConvertApp] Running pdflatex 3 times: [u'pdflatex', u'Untitled1.tex']
[NbConvertApp] Running bibtex 1 time: [u'bibtex', u'Untitled1']
[NbConvertApp] WARNING | bibtex had problems, most likely because there were no citations
[NbConvertApp] Removing temporary LaTeX files
[NbConvertApp] PDF successfully created
使用IPython 2.1,我得到了使用标准经典样式格式化的乳胶文件:
我的问题是:
我该怎么做才能从ipython命令获得以下样式?
为什么以上命令不能使作者出现?
和OP一样,我对nbconvert
IPython 2
输出nbconvert
。 由于转换器不再使用Sphinx文档类或Sphinx预处理系统,因此无法在nbconverter线上使用SphinxTransformer
调用。
Drop nbconvert
--post PDF
so nbconvert
只创建.tex
文件。 然后,编辑.tex
文件以使其更漂亮。 然后,在其上运行pdflatex
几次。
要使自己成为作者,请在他.tex
文件中的\\title
行后面添加如下所示的行:
\author{Never Saint}
您可以找到漂亮的模板,以帮助您在latextemplates.com
使输出看起来像您想要的。
另一种方法是滚动一个新模板,从.../IPython/nbconvert/templates/latex
。 以root用户身份,在article.tplx
和report.tplx
旁边添加article1.tplx
文件。 以下版本创建了一种我认为有用的不同输出样式。 “边距”块为LaTex生成前端内容,“predoc”块生成在文档开头插入的命令和文本。 我删掉了“maketitle”块,所以没有标题页。 如果您想要一个包含作者和日期的标题页,请删除我的空“maketitle”块。
用法: nbconvert --to latex yourNotebook.ipynb --template article1 --to PDF

解决这个问题是一个真正的痛苦的屁股。 我也喜欢iPython 0.x和1.x样式。 如果你必须拥有它,这就是你如何做到的。
人们提到你可以创建自己的模板。 那么,iPython 1.x拥有非常好的模板,所以让我们使用它们。 我假设你的机器上有root,因为我们要破解我们的iPython模板/ latex目录。

# update for some renaming that we just did
for tplx in old_latex_*.tplx; do
sed -i 's|sphinx.tplx|old_sphinx.tplx|' ${tplx}

现在,下一步是将补丁应用于sphinx.tplx。

剪切并粘贴上面的代码以创建补丁文件。 然后你可以应用它:
patch -p0 < sphinx_patch.patch
我们还没有完成。 这些模板需要一些支持。
我们将在您要转换的笔记本所在的目录中执行此操作。 我们要创建两个python文件。 第一个(我称之为oldschool.py)执行使用旧模板所必需的预处理。 它主要是从版本1.x iPython的nbconvert / transformers / sphinx.py中删除并被黑客攻击成为现代预处理器:
from __future__ import print_function, absolute_import
from IPython.nbconvert.preprocessors.base import Preprocessor
from IPython.utils.traitlets import Bool, Unicode

class MySphinxyLatexPreprocessor(Preprocessor):
interactive = Bool(False, config=True, help="""
Allows you to define whether or not the Sphinx exporter will prompt
you for input during the conversion process. If this is set to false,
the author, version, release, date, and chapter_style traits should
be set.

author = Unicode("Unknown Author", config=True, help="Author name")
version = Unicode("", config=True, help="""
Version number
You can leave this blank if you do not want to render a version number.
Example: "1.0.0"
""")
release = Unicode("", config=True, help="""
Release name
You can leave this blank if you do not want to render a release name.
Example: "Rough Draft"
""")
publish_date = Unicode("", config=True, help="""
Publish date
This is the date to render on the document as the publish date.
Leave this blank to default to todays date.
Example: "June 12, 1990"
""")
chapter_style = Unicode("Bjarne", config=True, help="""
Sphinx chapter style
This is the style to use for the chapter headers in the document.
You may choose one of the following:
"Bjarne" (default)
"Lenny"
"Glenn"
"Conny"
"Rejne"
"Sonny" (used for international documents)

"notebook" (default)

center_output = Bool(False, config=True, help="""

formatting is applied.
""")
use_headers = Bool(True, config=True, help="""

#Allow the user to override the title of the notebook (useful for
#fancy document titles that the file system doesn't support.)

def preprocess(self, nb, resources):

resources['metadata']['name'] = self.overridetitle.strip()
return nb, resources
最后一个文件很简单({config.py})。
c = get_config()
c.Exporter.preprocessors = ['oldschool.MySphinxyLatexPreprocessor']
现在,在命令行中,您可以执行以下操作:
ipython nbconvert example.ipynb --to latex --config config.py --template old_latex_article.tplx --post PDF
ipython nbconvert example.ipynb --to latex --config config.py --template old_latex_book.tplx --post PDF
如果你想使用basic(aka,{old_latex_basic.tplx}文件),你将不得不入侵我们添加到sphinx.tplx的主要代码块(%MEF NEW NEW MEF注释之间的部分)。
