How do I use a Python regex to match the function syntax of MATLAB? -


I am trying to find all input / output of all MATLAB functions in my internal library. I'm trying regex and new to use margin mode in Python's again library.

The MATLAB function syntax looks like this: 

  function output = funny_nm (input)

where signatures can span multiple lines is.

I started with a pattern: 

  re.compile (r "^. * Function (. *) = (. *) \ ([. \ N ] * \) $ ", Re.M

but I'm getting an unsupported template operator error. Any pointer is appreciated!

Edit:

I now have: 

  pattern = re.compile (r "^ \ S * Function (. *?) = [\ W \ n.] *? \ (. *? \) ", Re.m. re.Dotal)

which gives matches Like: 

  function [fcst, spread] = ... wolfstastmkeyt (r, ... mktVol, ... check, spread ..., ... fcstdays, ... Tsperyear if (calibrate) if (Nargin and lieutenant; 6) tsperyear = 252; Last temp = length (r)

My question is why does he first give additional row instead of stopping ) ?

If you are receiving a strange (internal) error occurs, Instead of re.m as re.compile ( re.template - currently using undocumented entry - Intended, and, in short, templates do not support RE repeat or back tracking). What can you value in your code before calling re.compile

Once fixed, we can discuss your desired Details of RE (in essence: if particles can be included in input part, otherwise again. DOTALL and some of your patterns should be written) - but this strange internal Deciding the occurrence of an error takes priority.

Edit : With the diagnosis of this bug (according to the comment below this Q), OP current question: re.Dotal at the end of the pattern Again Multitain , plus '$', plus everywhere-using Greedy Match (. * , instead of . *? for non-greedy), Be sure to all together that if regex matches, it will probably match widely as a swathe ... that's exactly what the combo is asking for. Probably the best to open the second question with a specific example: what is the input, what does the match, you like instead of regex to match, etc.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
