Python pygments 和 urwid.Edit 小部件(包含元组的列表)
我有一个问题。我尝试为终端制作一个编辑器。所以我使用 urwid,因为它支持按键和鼠标事件。我的设置是使用自定义 listwalker 和一行编辑小部件,并将标题设置为行号。问题是当它突出显示代码时,pygments 会逐行执行此操作。这是非常有效的。但有一个问题。例如,如果您有一个多行文档字符串,它会错误地突出显示。
1 """This is a docstring and it is be highlighted this whole line.
2 This is not higlighted"""#This should be a comment but is a part of the doc string
我无法理解它。为了突出显示我使用的代码,
list(lex(self._edit_text, self.parent.language))
它使用 urwid 调色板进行着色。
palette = [(token.Token.Literal.String.Doc, "dark magenta", "black"),]
# | | |
# the identifier fg bg
# if it isn't lined up, palette[0] is the identifier('"""*"""'),
# palette[1] is the foreground color and palette[2] is the background color.
这些行存储在一个简单的列表中
[urwid.Edit(" 1 ",'"""This is a docstring and it's highlighted as a string.'),\
urwid.Edit(" 2 ",\
'This is not higlighted"""#This should be a comment but is a part of the doc string')]
,突出显示函数会生成
[(Token.Literal.String.Doc, '"""This is a docstring and it's highlighted as a string.')\
(Token.Name,\
'This is not higlighted"""#This should be a comment but is a part of the doc string')]
,当它被处理时,它会从文本中生成一个字符串并存储在 self._edit_text 中。然后它创建一个存储为的元组列表,
self._attrib = [('ln_sel', 4), (Token.Name, 4), (Token.Text, 2), (Token.Operator.Word, 2),\
(Token.Text, 1), (Token.Operator.Word, 3), (Token.Text, 1), (Token.Name, 10), \
(Token.Literal.String, 61)]
这意味着 self._edit_text[0:4] 使用“ln_sel”调色板元组着色,而 self._edit_text[4:8] 使用“Token.Name”调色板元组着色。
我怎样才能做到这一点?
谢谢:)
I have a problem. I try to make an editor for the terminal. So I use urwid, since it supports both key and mouse events. My setup is to use a custom listwalker and one row Edit widget, and the caption set to a line number. The problem is when it highlights code pygments does this line by line. Which is very efficient. But there is a catch. For example if you have a multi line doc string, it gets highlighted wrong.
1 """This is a docstring and it is be highlighted this whole line.
2 This is not higlighted"""#This should be a comment but is a part of the doc string
I cannot wrap my head around it. To highlight the code I use
list(lex(self._edit_text, self.parent.language))
It is colored using a urwid palette.
palette = [(token.Token.Literal.String.Doc, "dark magenta", "black"),]
# | | |
# the identifier fg bg
# if it isn't lined up, palette[0] is the identifier('"""*"""'),
# palette[1] is the foreground color and palette[2] is the background color.
the lines is stored in a smiple list
[urwid.Edit(" 1 ",'"""This is a docstring and it's highlighted as a string.'),\
urwid.Edit(" 2 ",\
'This is not higlighted"""#This should be a comment but is a part of the doc string')]
and the highlighting function produces
[(Token.Literal.String.Doc, '"""This is a docstring and it's highlighted as a string.')\
(Token.Name,\
'This is not higlighted"""#This should be a comment but is a part of the doc string')]
And when it is processed it makes a string out of the text and is stored in self._edit_text. Then it makes a list of tuples stored as
self._attrib = [('ln_sel', 4), (Token.Name, 4), (Token.Text, 2), (Token.Operator.Word, 2),\
(Token.Text, 1), (Token.Operator.Word, 3), (Token.Text, 1), (Token.Name, 10), \
(Token.Literal.String, 61)]
Which means that the self._edit_text[0:4] is colored with "ln_sel" palette tuple, and that self._edit_text[4:8] is colored with "Token.Name" palette tuple.
How can I make this work?
Thanks :)
