Using python to dump hexadecimals into YAML

由 做~自己de王妃 提交于 2019-12-01 09:37:08
Now I'm dumping into a YAML document. It's working as it should for the most part. When I try to dump a hexadecimal such as "0x2A" it converts to 42. Isn't there any way to maintain it's hexadecimal format? A string won't work sadly. And int( 0x2A, 16) also just gives me a 42. You may be looking for hex(0x2a) == hex(42) == '0x2a' . Unless you're looking for a way to convince your existing dumping function to use hexadecimal instead of decimal notation... Answering to your comment below, if the problem is that you want upper case letters for the hexadecimal digits (but lower case for the 0x )

Generated SQL with PredicateBuilder, LINQPad and operator ANY

问题 I previously asked a question about chaining conditions in Linq To Entities. Now I use LinqKit and everything works fine. I want to see the generated SQL and after reading this answer, I use LinqPad. This is my statement: var predProduct = PredicateBuilder.True<Product>(); var predColorLanguage = PredicateBuilder.True<ColorLanguage>(); predProduct = predProduct.And(p => p.IsComplete); predColorLanguage = predColorLanguage.And(c => c.IdColorEntity.Products.AsQueryable().Any(expr));

Pickle dump with progress bar

由 五迷三道 提交于 2019-12-01 03:45:47
I've a really big json object that I want to dump into a pickle file. Is there a way to display a progress bar while using pickle.dump ? The only way that I know of is to define getstate/setstate methods to return "sub objects" which can refresh the GUI when the get pickled/unpickled. For example, if your object is a list, you could use something like this: import pickle class SubList: on_pickling = None def __init__(self, sublist): print('SubList', sublist) self.data = sublist def __getstate__(self): if SubList.on_pickling is not None: print('SubList pickle state fetch: calling sub callback')

How can I dump the entire Web DOM in its current state in Chrome?

由 社会主义新天地 提交于 2019-12-01 02:12:42
I want to dump the current DOM to a file and be able to view it offline. Essentially, I have an outdated version of a page that I would like to keep around for comparison. As soon as I close my browser, I'm going to lose it so I would like to save the DOM exactly as it is. There is already an answer for doing this in Firefox but how do I do it in Chrome? Using the Web Inspector (F12), go to the Elements tab, right click on the <html> tag in your code and select 'Copy as HTML'. Then paste that into a new file and save. I am currently using version 53.0.2785.113 m of Chrome. The other answers no

PL/SQL developer import dump

I have a dump file which includes two tables. Now I need to import this dump file. I was instructed to create two tablespaces beforehands.Now how do I import this dump file to these tablespaces. I'm using PL/SQL developer. You cannot import a dump file from PL/SQL developer. Instead, you have to do it from the command line. Furthermore, you need access to the file system of the database server since you have to put the dump file in a directory directly accessible by Oracle. The tool to import the dump file is called impdp (in earlier version, it was imp ). My experience is that you need

What is the equivalent of var_dump() in R?

由 ≡放荡痞女 提交于 2019-11-30 19:23:43
I'm looking for a function to dump variables and objects, with human readable explanations of their data types. For instance, in php var_dump does this. $foo = array(); $foo[] = 1; $foo['moo'] = 2; var_dump($foo); Yields: array(2) { [0]=> int(1) ["moo"]=> int(2) } A few examples: foo <- data.frame(1:12,12:1) foo ## What's inside? dput(foo) ## Details on the structure, names, and class str(foo) ## Gives you a quick look at the variable structure Output on screen: foo <- data.frame(1:12,12:1) foo X1.12 X12.1 1 1 12 2 2 11 3 3 10 4 4 9 5 5 8 6 6 7 7 7 6 8 8 5 9 9 4 10 10 3 11 11 2 12 12 1 > dput

Exclude function definitions when dumping a PostgreSQL database

由 别等时光非礼了梦想. 提交于 2019-11-30 17:29:36
问题 I have a PostgreSQL database with PostGIS functions loaded into it. I would like to dump out the schema of the database, but pg_dump -s dumps out the functions along with the table definitions. Is there a way to exclude the functions and just dump the table definitions? 回答1: For all I know, pg_dump and pg_dumpall do not support any such restriction. You could move all your functions to a dedicated schema which you could exclude from the dump like this: pg_dump mydb -N function_schema > mydump

How to use redis' `DUMP` and `RESTORE` (offline)?

由 我的梦境 提交于 2019-11-30 14:43:27
问题 I tried redis's DUMP command, redirect to file (or pipe), but RESTORE report this error: $ redis-cli dump test > /tmp/test.dump $ cat /tmp/test.dump | redis-cli -x restore test1 0 (error) ERR DUMP payload version or checksum are wrong $ redis-cli dump test | redis-cli -x restore test1 0 (error) ERR DUMP payload version or checksum are wrong I am aware that MIGRATE can do this online, but MIGRATE also delete that key from original server, and I don't want my redis expose to public internet.

How to view the type of a variable in PL/SQL?

由 做~自己de王妃 提交于 2019-11-30 13:37:57
Is there a function in PL/SQL to show a variable's exact type, like the DUMP function in SQL? I've tried the following DECLARE l_variable INTEGER := 1; BEGIN DBMS_OUTPUT.PUT_LINE (DUMP (l_variable)); END; But it gives the following error: PLS-00204: function or pseudo-column 'DUMP' may be used inside a SQL statement only You can create this function using PL/Scope . But it won't work with anonymous blocks, and you'll need to reference the variable as a string. create or replace function get_plsql_type_name ( p_object_name varchar2, p_name varchar2 ) return varchar2 is v_type_name varchar2(4000
