I can't understand how to work with `.jslib` files. I don't understand the syntax of t$$anonymous$$s type of file. Also I couldn't find any easy explanation of it
The problem started when I tried to make two functions global for all `.jslib` files:
/**
* @param {string} str
* @returns {string}
*/
function StrJSToStrCS (str) {
const bufferSize = lengthBytesUTF8(str) + 1;
const buffer = _malloc(bufferSize);
stringToUTF8(str, buffer, bufferSize);
return buffer;
}
/**
* @param {string} str
* @returns {string}
*/
function StrCSToStrJS (str) {
return UTF8ToString(str);
}
What I already tried:
+ To define these two functions in the same file
function StrJSToStrCS (str) {
const bufferSize = lengthBytesUTF8(str) + 1;
const buffer = _malloc(bufferSize);
stringToUTF8(str, buffer, bufferSize);
return buffer;
}
function StrCSToStrJS (str) {
return UTF8ToString(str);
}
const lib = {
Hello: function () {
return StrJSToStrCS('HELLO WORLD!');
},
ConsoleLog: function (str) {
console.log(StrCSToStrJS(str));
}
};
mergeInto(LibraryManager.library, lib);
+ To define these two functions in `script` tag in `.html` after reading [t$$anonymous$$s](https://emscripten.org/docs/porting/connecting_cpp_and_javascript/Interacting-with-code.html#javascript-limits-in-library-files). If it's important the script tag I inserted at the bottom of `body` tag
HTML file
JavaScript file
const lib = {
Hello: function () {
return StrJSToStrCS('HELLO WORLD!');
},
ConsoleLog: function (str) {
console.log(StrCSToStrJS(str));
}
};
mergeInto(LibraryManager.library, lib);
+ To define these functions in `.jspre` file after reading [t$$anonymous$$s](https://medium.com/@depanther/unity-webgl-secrets-b6ddf214f1fd)
> the .jspre files are added to the build using the --pre-js option, w$$anonymous$$le the .jslib are added using the --js-library option
`.jspre` file:
function StrJSToStrCS (str) {
const bufferSize = lengthBytesUTF8(str) + 1;
const buffer = _malloc(bufferSize);
stringToUTF8(str, buffer, bufferSize);
return buffer;
}
function StrCSToStrJS (str) {
return UTF8ToString(str);
}
`.jslib` file:
const lib = {
Hello: function () {
return StrJSToStrCS('HELLO WORLD!');
},
ConsoleLog: function (str) {
console.log(StrCSToStrJS(str));
}
};
mergeInto(LibraryManager.library, lib);
+ To simply define these functions as methods in the same object:
const lib = {
StrJSToStrCS: function(str) {
const bufferSize = lengthBytesUTF8(str) + 1;
const buffer = _malloc(bufferSize);
stringToUTF8(str, buffer, bufferSize);
return buffer;
},
StrCSToStrJS: function(str) {
return UTF8ToString(str);
},
Hello: function() {
return t$$anonymous$$s.StrJSToStrCS('HELLO WORLD!');
},
ConsoleLog: function(str) {
console.log(t$$anonymous$$s.StrCSToStrJS(str));
}
}
mergeInto(LibraryManager.library, lib);
But whatever I do, he writes every time in console that `StrJSToStrCS/StrCSToStrJS` is not defined
I don't understand at all why the last method doesn't work. Isn't `lib` just a simple object?
Is it possible to make these two functions global for all `.jslib` files?
