QUESTION
Im fairly new to C#, but I have a fair understanding of SQL
I have 1000's of XML files in a folder. I need to extract certain elements and store them in SQL. The XMl will have Segments with Descendants that I need to store in SQL. As an example, the below is a warehouse order 123456 which has a number of orderlines, and each orderline has a product / code segment.
I have a SQL table with 5 columns - Client, Warehouse, OrderReference, CustomerReference,Type and ProductCode.
For example

I'm a newbie at maya c++ API making.
I made a byte of maya c++ api to my computer with Visual studio.
My .mll
filetype worked well on my computer with devkit using mel(loadPlugin ~~)
.
But when the code is run on other computer, it doesn't work. I get the error:
...ANSWER
Answered 2020-Sep-02 at 08:37These types of error have two reasons in most cases: 1. Build in debug mode, not release mode. Debug mode will rely on debug libraries which are only available if the development environment is installed on the computer, e.g. VisualStudio. 2. The plugin needs an additional library, e.g. a alembic reader will need the alembic library.
QUESTION
I want to add the support of structured references with Excel tables to my lexer & parser of Excel formulas.
I added the following regular expressions to lexer_structref.mll
:
ANSWER
Answered 2020-Aug-18 at 02:28Besides the comments which help optimize the lexer, there is a workaround: ocamllex -ml
does not limit the number of states, transitions, table size. Use it when there is no other choices.
QUESTION
I'm writing a lexer and parser in ocamllex and ocamlyacc as follows. function_name
and table_name
are same regular expression, i.e., a string containing only english alphabets. The only way to determine if a string is function_name
or table_name
is to check its surroundings. For example, if such a string is surrounded by [
and ]
, then we know that it is a table_name
. Here is the current code:
In lexer.mll

ANSWER
Answered 2020-Aug-12 at 06:08You should avoid trying to get the lexer to do the parser's work. The lexer should just identify lexemes; it should not try to figured out where a lexeme fits into the syntax. So in your (simplified) example, there should be only one lexical type, name
. The parser will figure it out from there.
But it seems, from the comments, that in the unsimplified original, the two patterns are overlapping rather than identical. That's more annoying, although it's only slightly more complicated. Basically, you need to separate out the common pattern as one lexical type, and then add the additional matches as one or two other lexical types (depending on whether or not one pattern is a strict superset of the other).
That might not be too difficult, depending on the precise relationship between the two patterns. You might be able to find a very simple solution by writing the patterns in the correct order, for example, because of the longest match rule:
If several regular expressions match a prefix of the input, the “longest match” rule applies: the regular expression that matches the longest prefix of the input is selected. In case of tie, the regular expression that occurs earlier in the rule is selected.
Most of the time, that's all it takes: first define the intersection of the two patterns as a based lexeme, and then add the full lexical patterns of each contextual type to provide additional matches. Your parser will then have to match name | function_name
in one context and name | table_name
in the other context. But that's not too bad.
Where it will fail is when an input stream cannot be unambiguously divided in lexemes. For example, suppose that in a function context, a name could include a ?
character, but in a table context the ?
is a valid postscript operator. In that case, you have to actively prevent foo?
from being analysed as a single token in the table context, which means that the lexer does have to be aware of parser context.

I'm using lighthouse-php to make a graphql api and I'm having a trouble changing middleware (it will be deprecated in new versions) directive to guard.
...ANSWER
Answered 2020-May-01 at 13:54In the meantime I've found another solution mentioned in the documentation:
https://lighthouse-php.com/master/security/authentication.html#global
So in short, I needed to add the AttemptAuthentication middleware to the lighthouse config. I use this with @auth(guard: "api") added to all my types.
QUESTION
Situation: I am currently working on visualizing the results of a huggingface transformers machine learning model I have been building using the LIME package following this tutorial.
Complication: My code is set up and runs well until I create the LIME explainer object. At this point I get a memory error.
Question: What am I doing wrong? Why am I running into a memory error?
Code: Here is my code (you should be able to just copy-paste this into google colab and run the whole thing)
...ANSWER
Answered 2020-Apr-02 at 10:21Ended up solving this by re-implementing along the lines of this GitHub post: https://github.com/marcotcr/lime/issues/409
My code is now very different from the above - probably makes sense if you look to the GitHub post for guidance if you're running into similar issues.

Answered 2019-Oct-14 at 06:31It seems that rebing/graphql-laravel

It seems also that webonyx/graphql-php
is already required in your composer file so you need to update the sub-dependency with
composer update webonyx/graphql-php rebing/graphql-laravel
