Im working on a project that uses i18next with react and typescript, where translationkeys are defined in .json files.
One drawback of switching to json for the translation files, is that we can no longer use the intellij idea "Go to declaration" or ctrl + left-click feature, to quickly navigate from a key usage in typescript, to its declaration in the json file.
Is there any way to enable this without requiring all developers to download some third-party intellij plugin?
I've googled for hours for any information about this.
I've made a d.ts file to enable strong typing for where translationkeys are used. What strikes me as odd is that intellij/typescript is able to know when a key doesent exist and warns about it, but at the same time doesent know "where" that key exists whenever i type a correct key.
I also set resolveJsonModule:true in tsconfig, but to my limited understanding it doesent seem relevant.
This is not technically possible because commands like Go To Declaration will look for a declaration in a source code file (think .ts or .js or .d.ts) whereas you want to go ...to its declaration in the json file.
The resolveJsonModule flag won't help you either because as per the docs:
Allows importing modules with a ‘.json’ extension, which is a common practice in node projects. This includes generating a type for the import based on the static JSON shape.
One possible solution is to create a build script to take your .json file and output a .js or .ts file containing the same content, then IDE commands like Go To Declaration will jump to that file.
In summary: you will need some kind of plugin, or a custom build script.
DISCLAIMER: I don't use i18next or react, this answer is based on my understanding of both TypeScript and the JetBrains Rider IDE (which is like IntelliJ).

In short: I am trying to load a csv file but the program always overwrites the existing file as an empty new file.
Longer: I am pretty new to Fortran, so bear with me. I am trying to read data from a csv file into a fortran program. Now I didn't write the program and it is pretty big, so I can't post the whole thing here. The program consists of a whole bunch of .f90 files and everything is compiled using a makefile. Now since I am loading the gcc module before compiling, I am assuming that it is compiled using GNU Fortran, because it is part of gcc. (idk how to find out if that is correct)
The compiler returns an executable in a different directory. When I execute the program in that directory it apparently overwrites the existing .csv file with a new blank one, so the program only reads "End of File". I don't know why it always creates a new file, how do I stop it from doing so?
As a side note, the csv file I am trying to read simply consists of a single column of floats, e.g.
"0.01, 0.13, 0.041,..." etc.
The code that I inserted into a subroutine of one of the .f90 files is the following:
real*8, dimension(nz) :: Nsq
integer :: i
open(10, file='Nsq.csv')
do i=1,20
read(10, *) Nsq(i)
enddo
close(10)
I have also tried to write a small test program, essentially running the same code as above. That one works just fine and outputs the contents of the csv file without any issues. For that one I use gfortran to compile it.
I have no experience in Fortran at all, so I am completely stumped, why this happens. I know the chances are slim that you guys can help me with this, since I can't provide the whole source code. But maybe someone has an idea why this occurs. Maybe you know an alternate way of reading csv files?
Thanks for your time.
The open-statement in Fortran OPEN(connect-spec-list), has a lot of connection specifications which define how an external file should be managed (see. Fortran 2018 Standard sec 12.5.6).
When you open a file using the simplest form of the open-statement:
OPEN(unit=unitid,file="filename")
A lot of default assumptions are made such as: ACCESS="SEQUENTIAL", ASYNCHRONOUS="NO", BLANK="NULL", .... The most important ones, however, are ACTION and STATUS which define the purpose of the file. The action specification states if you want to use the file for reading, writing or both, while the status essentially defines if we work on an existing file or not, and what we should do with it (replace it, keep it, ...)
Both these specifications have a default compiler dependent state.
In the Intel compiler suit, the default is action="readwrite", status="unknown" (see here and here)
Intel defines the status="unknown" as :Indicates the file may or may not exist. If the file does not exist, a new file is created and its status changes to 'OLD'.
The Gnu compiler suit has a different take on this. The default action is defined by a set of rules which depend on its accessibility if the file exists (+rw,+r-w,-r+w) (see here). The behaviour for the default action="unknown" is not documented but seems to be REWRITE (see Default Status of "Unknown" in Open)
It is advised to use a proper method if you know what you want to do with the file:
OPEN(newunit=unitid, file="filename", action="read", status="old")
I've never worked with web pages before and I'd like to know how best to automate the following through programming/scripting:
go to http://financials.morningstar.com/ratios/r.html?t=GMCR®ion=USA&culture=en_US
invoke the 'Export to CSV' button near the top right
save this file into local directory
parse file
Part 4 doesn't need to use the same language as for 1-3 but ideally I would like to do everything in one shot using one language.
I noticed that if I hover my mouse over the button it says: javascript:exportKeyStat2CSV(); Is this a java function I could call somehow?
Any suggestions are appreciated.
It's a JavaScript function, which is not Java!
At first glance, this may seem like you need to execute Javascript to get it done, but if you look at the source of the document, you can see the function is simply implemented like this:
function exportKeyStat2CSV(){
var orderby = SRT_keyStuts.getOrderFromCookie("order");
var urlstr = "//financials.morningstar.com/ajax/exportKR2CSV.html?&callback=?&t=XNAS:GMCR®ion=usa&culture=en-US&cur=&order="+orderby;
document.location = urlstr;
}
So, it builds a url, which is completely fixed, except the order by part, which is taken from a cookie. Then it simply navigates to that url by setting document.location. A small test shows you even get a csv file if you leave the order by part empty, so probably, you can just download the CSV from the base url that is in the code.
Downloading can be done using various tools, for instance WGet for Windows. See SuperUser for more possibilities. Anyway, 'step 1 to 3' is actually just a single command.
After that, you just need to parse the file. Parsing CSV files can be done using batch, and there are several examples available. I won't get into details, since you didn't provide any in your question.
PS. I'd check their terms of use before you actually implement this.
The button directs me to this link:
http://financials.morningstar.com/ajax/exportKR2CSV.html?&callback=?&t=XNAS:GMCR®ion=usa&culture=en-US&cur=&order=asc
You could use the Python 3 module urllib and fetch the file, save it using the os or shutil modules, then parse it using one of the many CSV parsing modules, or by making your own.
I'm writing a simple Erlang program that requests an URL and parses the response as JSON.
To do that, I need to use a Library called Jiffy. I downloaded and compiled it, and now i have a .beam file along with a .app file. My question is: How do I use it? How do I include this library in my program?. I cannot understand why I can't find an answer on the web for something that must be very crucial.
Erlang has an include syntax, but receives a .hrl file.
Thanks!
You don't need to include the file in your project. In Erlang, it is at run time that the code will try to find any function. So the module you are using must be in the search path of the VM which run your code at the point you need it, that's all.
For this you can add files to your path when you start erlang: erl -pa your/path/to/beam (it exists also -pz see erlang doc)
Note that it is also possible to modify the path from the application itself using code:add_path(Dir).
You should have a look to the OTP way to build applications in erlang documentation or Learn You Some Erlang, and also look at Rebar a tool that helps you to manage erlang application (for example starting with rebar or rebar wiki)
To add to Pascal's answer, yes Erlang will search for your files at runtime and you can add extra paths as command line arguments.
However, when you build a project of a scale that you are including other libraries, you should be building an Erlang application. This normally entails using rebar.
When using rebar, your app should have a deps/ directory. To include jiffy in your project, it is easiest to simply clone the repo into deps/jiffy. That is all that needs to be done for you to do something like jiffy:decode(Data) in your project.
Additionally, you can specify additional include files in your rebar.config file by adding extra lines {erl_opts, [{i, "./Some/path/to/file"}]}.. rebar will then look for file.so using that path.
Let's say that i have file /home/foo/myfile without extension. Is there option to add syntax setting into this file? In vim it's :set syntax=javascript. I know that in Sublime you can set default syntax color.
There's similar question Changing default syntax based on filename but there you set specific filename. I need to set it in file itself, since i have a lot of different files without extension.
The package ApplySyntax should be able to do what you want.
ApplySyntax is a plugin for Sublime Text 2 and 3 that allows you to
detect and apply the syntax of files that might not otherwise be
detected properly. For example, files with the .rb extension are
usually Ruby files, but when they are found in a Rails project, they
could be RSpec spec files, Cucumber step files, Ruby on Rails files
(controllers, models, etc), or just plain Ruby files. This is actually
the problem I was trying to solve when I started working on this
plugin.
Set your rules/filenames in the ApplySyntax.sublime-settings file:
// "rules" is a list (array) of checks that you want to make against
the file in the current view. A rule is either a regular expression
or a function. If using a regular expression, you can specify
whether you want it tested against the "file_name" or the first
line of the file (think shebangs and xml files). If the rule is a
function, you must provide the path to the file containing the
function and the name of the function to call. When this function is
called, the "file_name" will be passed to it as the only argument.
You are free to do whatever you want in your function, just return
True or False.
you can do this on the fly through the command menu (on OSX cmd+shift+p, windows ctrl+shift+p) then type what you need (e.g. javascript) and it will come up in the list set syntax: JavaScript.
Sublime will remember this until you close the file
I'm currently looking for a way to add data to an already compiled ELF executable, i.e. embedding a file into the executable without recompiling it.
I could easily do that by using cat myexe mydata > myexe_with_mydata, but I couldn't access the data from the executable because I don't know the size of the original executable.
Does anyone have an idea of how I could implement this ? I thought of adding a section to the executable or using a special marker (0xBADBEEFC0FFEE for example) to detect the beginning of the data in the executable, but I do not know if there is a more beautiful way to do it.
Thanks in advance.
You could add the file to the elf file as a special section with objcopy(1):
objcopy --add-section sname=file oldelf newelf
will add the file to oldelf and write the results to newelf (oldelf won't be modified)
You can then use libbfd to read the elf file and extract the section by name, or just roll your own code that reads the section table and finds you section. Make sure to use a section name that doesn't collide with anything the system is expecting -- as long as your name doesn't start with a ., you should be fine.
I've created a small library called elfdataembed which provides a simple interface for extracting/referencing sections embedded using objcopy. This allows you to pass the offset/size to another tool, or reference it directly from the runtime using file descriptors. Hopefully this will help someone in the future.
It's worth mentioning this approach is more efficient than compiling to a symbol, as it allows external tools to reference the data without needing to be extracted, and it also doesn't require the entire binary to be loaded into memory in order to extract/reference it.
