python - What do I do with a Concrete Syntax Tree? -


I am using a simple parsing tree for grammar. Here is an example: ('instructions', [('direction', [(('name', 'retrieve']), ('instructions', using tree lists and tuples. , My question is what ([name ',' committed ']]), (' filename ', [(' name ',' f30502 ')])]]

my What is the question at this point, what do I do with it? I know what I am trying to do, but a lot depends, but I would like to consume / use paras trees. Ray has not been able to find much, only making them

P> CST (Concrete Syntax Trees) are difficult to work with so they are usually converted into AST (Abstract Syntax Trees) for further processing (details in the same article). For example, (Component which changes the python source code in Python VM bytecode) CST as part of its function Changes in ST.

Now, it really depends on your ultimate goal. You're doing parsing? What do you want to do with it? If you are rebuilding the flow of a classical compilation, then possibly going to convert to AST is a good way to move, otherwise you can get enough CST - all depends on what you want.

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...
