Using pyparsing to parse infix expression
I am learning Paul McGuire’s fabulous pyparsing Python module. I’m posting this for discussion and hopefully to get a deeper insight into pyparsing.
pyparsing – back to basics
In attempting to put together a very simple example to illustrate an issue I’m having with pyparsing, I have found that I can’t get my simple example to work – this example is barely more complex than Hello, World!
How to make sure element has parsing precedence before other elements in pyparsing?
I have a simple markup grammar that can have matched and standalone tags:
pyparsing transform_string with negative lookahead
I’m trying to implement simple shell-style string variable interpolation with $varname syntax, using pyparsing. For example, if I have a variable foo
with value "bar"
, then transform "x $foo x"
to "x bar x"
.
