kandi X-RAY | rawhash Summary
An experimental binary friendly alternative to using a hash as a key:value cache, for node.js. Keys are binary Buffer objects rather than strings. Values are arbitrary objects. rawhash is built on google-sparsehash (not included) and murmurhash3 (included).

QUESTION
I have a simple script written to hash a cell, however it doesn't work within and array formula, and I am having a hard time figure out how to add that functionality.

In order to use an array you need to map the input. Using a simple else if you can test if the input is an array or a single value.
QUESTION
I implemented an MD5 formula as mentioned here: Hash of a cell text in Google Spreadsheet.
...ANSWER
Answered 2019-Mar-10 at 01:14How about this modification?
For example, when the current script of your question is used, in the case that MD5(O2:O)
is used as a custom function, input
of function MD5(input) {}
is 2 dimentional array like [[value of O2], [value of O3],,,]
. But in your script, the result is returned by inputting a value which is not an array. By this, the error shown in your question occurs. So in order to input and output the array, the script is required to be modified for this situation as follows.
QUESTION
Im trying to implement the Google Safebrowsing update API v4 in PHP. But I can't figure how to correctly decode the rawHashes.
(The rawHashes are 4-bytes-truncated sha256 hashes and then concatenated).
I am trying the native base64_decode of PHP but I can't fully decode the string, and I don't know what the next step is.
According to the API documentation here's how the rawhashes are encoded :
...ANSWER
Answered 2019-Apr-22 at 14:34From what I know of base64_decode, it just works. Something must be wrong in your $rawHashes string. If you have line breaks in your string, you need to get rid of them by replacing them with an empty string. The hash that base64_decode needs should be one long line of base64 encoded string. It is not uncommon to receive a hash that is broken into multiple lines.
Try this ...

Here's my crystal code, in snippets, but I think it's all there:
...ANSWER
Answered 2018-Oct-31 at 11:50The compiler can't infer ivar types from the return type of method calls (like hash_value.as_h
). The reference of Type inference lists all rules where the compiler can infer ivar types.
Infering the type from method calls is probably not impossible, but more complicated. It might come to the language at some point, but for now you'll have to use an explicit type annotation such as @hash_value : Hash(JSON::Any, JSON::Any)
.
QUESTION
I have to make a url request with Google Apps Script and for that, I need to enncode my login and password using a sha 1 algorithm and a base64 encoding. In the documantation for the request, I have the following php code :
$string = "loginpassword2017-15-04T09:25:00";
$hash = sha1($string, true);
$hash = base64_encode($hash);
So in Google Apps Script, i use the following code :
function GetSHA1(input) {
var rawHash = Utilities.computeDigest(Utilities.DigestAlgorithm.SHA_1, input);
var txtHash = '';
for (j = 0; j
and then the function
Utilities.base64Encode
Finally I make the url request but authentication is unsuccessful. Does someone know how to do a php sha1 and base64encode in Google Apps Script ? Thanks
...ANSWER
Answered 2017-Dec-04 at 15:36You can pass the Byte[]
array returned from the Utilities::computeDigest
directly to a Utilities::base64EncodeWebSafe
invocation. So you could do something like the following:
QUESTION
I have two Google sheets workbooks.
One is the "master" source of lookup data with a key based on manufacturer item #, which could be anything from 1234 to A-01/234-Name_1. This sheet, referenced via SpreadsheetApp.openByUrl, has 18,000 rows and 13 columns. The key column has been converted to plain text and the sheet is sorted by this column.
The second is the "template" where people enter item #s that they need to look up against the master, typically 20 - 1500 items at a time.
The script is in the template. It is very slow and routinely times out after 30 minutes. It was written by someone else and I am new to App Script, but I think I've managed to understand what the script is doing and where the bottleneck is occurring.
It does a bunch of stuff, but this is the meat of the lookup:
...ANSWER
Answered 2017-Oct-31 at 17:58It sounds like you hit on the right approach with attempting to move the appendRow() call out of the loop. Anytime you are reading or writing to a spreadsheet you can expect the individual call to take 1 to 2 seconds, so this will eat up a lot of time when you get matches. Storing the matches in an array and writing them all at once is the way to go.
Another thing I notice is that your script calls getValues() in the actual for loop condition statement. The condition statement is executed each time on each iteration of the loop, so this is potentially wasting a lot of time even when you don't have matches.
A final tweak that may be helpful depending on your desired behaviour. You can stop the inner for loop after it finds the first match, which, if you only care about the first match or know there will only be one match, will save you a lot of iterations. To do this, put "break
" immediately after the retreiveddata.push(masterdata[j]);
line.
To fix the getValues issue, Change:
