Diferenças com a marcação LaTeX¶

Apesar da linguagem de marcação ser diferente, muitos dos conceitos e tipos de marcação dos documentos LaTeX foram mantidos – ambientes como diretivas reST, comando inline como roles do reST e assim vai.

No entanto, existem algumas diferenças na forma que esses elementos funcionam, parcialmente por conta de melhorias no Sphinx. Essa seção lista essas diferenças com o objetivo de dar para os que estão familiarizados com o estilo antigo uma revisão rápida do que podem encontrar.

Marcação Inline¶

Essas mudanças foram feitas na marcação inline:

Papéis com referências cruzadas

Most of the following semantic roles existed previously as inline commands, but didn’t do anything except formatting the content as code. Now, they cross-reference to known targets (some names have also been shortened):

mod (previously refmodule or module)

func (previously function)

data (new)

const

class

meth (previously method)

attr (previously member)

exc (previously exception)

cdata

cfunc (previously cfunction)

cmacro (previously csimplemacro)

ctype

Also different is the handling of func and meth: while previously parentheses were added to the callable name (like \func{str()}), they are now appended by the build system – appending them in the source will result in double parentheses. This also means that :func:`str(object)` will not work as expected – use ``str(object)`` instead!
Inline commands implemented as directives

These were inline commands in LaTeX, but are now directives in reST:

deprecated

versionadded

versionchanged

These are used like so:
```
.. deprecated:: 2.5
   Reason of deprecation.
```
Also, no period is appended to the text for versionadded and versionchanged.

note

warning

These are used like so:
```
.. note::

   Content of note.
```
Otherwise changed commands

The samp command previously formatted code and added quotation marks around it. The samp role, however, features a new highlighting system just like file does:

:samp:`open({filename}, {mode})` results in open(filename, mode)
Dropped commands

These were commands in LaTeX, but are not available as roles:

bfcode

character (use ``'c'``)

citetitle (use `Title <URL>`_)

code (use ``code``)

email (just write the address in body text)

filenq

filevar (use the {...} highlighting feature of file)

programopt, longprogramopt (use option)

ulink (use `Title <URL>`_)

url (just write the URL in body text)

var (use *var*)

infinity, plusminus (use the Unicode character)

shortversion, version (use the |version| and |release| substitutions)

emph, strong (use the reST markup)
Backslash escaping

In reST, a backslash must be escaped in normal text, and in the content of roles. However, in code literals and literal blocks, it must not be escaped. Example: :file:`C:\\Temp\\my.tmp` vs. ``open("C:\Temp\my.tmp")``.

Information units¶

Information units (…desc environments) have been made reST directives. These changes to information units should be noted:

New names

“desc” has been removed from every name. Additionally, these directives have new names:

c:function (previously cfuncdesc)

cmacro (previously csimplemacrodesc)

exception (previously excdesc)

function (previously funcdesc)

attribute (previously memberdesc)

The classdesc* and excclassdesc environments have been dropped, the class and exception directives support classes documented with and without constructor arguments.
Multiple objects

The equivalent of the …line commands is:
```
.. function:: do_foo(bar)
              do_bar(baz)

   Description of the functions.
```
IOW, just give one signatures per line, at the same indentation level.
Arguments

There is no optional command. Just give function signatures like they should appear in the output:
```
.. function:: open(filename[, mode[, buffering]])

   Description.
```
Note: markup in the signature is not supported.
Indexing

The …descni environments have been dropped. To mark an information unit as unsuitable for index entry generation, use the noindex option like so:
```
.. function:: foo_*
   :noindex:

   Description.
```
New information units

There are new generic information units: One is called “describe” and can be used to document things that are not covered by the other units:
```
.. describe:: a == b

   The equals operator.
```
The others are:
```
.. cmdoption:: -O

   Describes a command-line option.

.. envvar:: PYTHONINSPECT

   Describes an environment variable.
```

Structure¶

The LaTeX docs were split in several toplevel manuals. Now, all files are part of the same documentation tree, as indicated by the toctree directives in the sources (though individual output formats may choose to split them up into parts again). Every toctree directive embeds other files as subdocuments of the current file (this structure is not necessarily mirrored in the filesystem layout). The toplevel file is contents.rst.

However, most of the old directory structure has been kept, with the directories renamed as follows:

api -> c-api
dist -> distutils, with the single TeX file split up
doc -> documenting
ext -> extending
inst -> installing
lib -> library
mac -> merged into library, with mac/using.tex moved to using/mac.rst
ref -> reference
tut -> tutorial, with the single TeX file split up
