[go-nuts] Re: JSON Compare

[Maxime Soulé]

Hi,

You can have a look at go-testdeep [1] and its JSON [2] operator.
go-testddep is tailored for tests, but it provides EqDeeplyError [3] 
function that can perhaps be useful in your use case.

json1 := json.RawMessage(`{"foo":{"a":1}}`)
json2 := json.RawMessage(`{"foo":{"b":8}}`)
err := td.EqDeeplyError(json1, td.JSON(json2))

→ https://go.dev/play/p/6dtEB5lZOBG

Regards,

Max.

[go-nuts] [ANN] GraphBLAS binding for Go

[Pascal Costanza]

Hi,


I am happy to announce a library that we have been working on at Intel.

It is a Go binding for the GraphBLAS  C API that 
calls into the widely used SuiteSparse:GraphBLAS C library.


You can find the Go binding at forGraphBLASGo 
 and some example algorithms at 
forLAGraphGo .


GraphBLAS is a specification for an API that defines standard building 
blocks for expressing graph algorithms in the language of linear algebra. 
It consists of data types for opaque representations of sparse matrices, 
vectors and scalars over the usual elementary types (Booloans, integers, 
floating point numbers), as well as user-defined element types. Operations 
on those data types include matrix-vector, vector-matrix, matrix-matrix 
multiplications, element-wise addition and multiplication, and so on. Apart 
from the usual integer and floating point addition and multiplication, 
client programs can use other arbitrary operators with these high-level 
operations, represented as monoids or semirings, to express a wide range of 
powerful algorithms.


SuiteSparse:GraphBLAS is a complete implementation of GraphBLAS in the C 
programming language. It is used heavily in production. For example, it is 
used as the underlying graph engine in FalkorDB (previously RedisGraph), 
and as the built-in sparse matrix multiply in MATLAB. Several bindings 
exist for SuiteSparse:GraphBLAS for Python, Julia, and PostgreSQL.


The forGraphBLASGo library is a binding that defines a Go API for GraphBLAS 
and the SuiteSparse:GraphBLAS extensions. It strives to adhere to Go 
programming style as much as possible. Most prominently, it uses type 
parameters that have been introduced in Go 1.18 to make the various 
GraphBLAS object types generic, for added type safety. Other supported Go 
features include: using multiple return values instead of reference 
parameters, and Go-style error handling.


We consider the forGraphBLASGo library as quite mature. However, we haven’t 
yet assigned the version number 1.0.0 to it yet. If you have any feedback 
or suggestions for improvement, please let us know.


The forLAGraphGo library is less mature and still work in progress.

Looking forward to hearing what you think about this library.


Thanks a lot,

Pascal

Re: [go-nuts] Re: 'go run hello.go' taking ~30 seconds on windows

Windows defender slows apps first time ran. I had replaced several hard 
disks(HDDs and SSDs) and reinstalled OS systems(win7,win10,win11), nothing 
changed. After turning off  windows defender, everything returns to normal.

 The answer is always the same: turn off your antivirus software for 
 your development tree. 

 Such delays are due to "heuristics" usually implemented by uploading 
 your exe to the vendor. 
 Root cause is that after 12 years AV vendors still can not cope with 
 what they pereceive 
 a "non standard" linker, ie. a Go's one. 

 hope this helps,
