Summary:
TurboModules depend on a getConstants method. Existing ObjectiveC modules do not have this method. Therefore, I moved the contents of `constantsToExport` to `getConstants` and then had `constantsToExports` call `getConstants`.
facebook
Since all NativeModules will eventually need to be migrated to the TurboModule system, I didn't restrict this to just the NativeModules in Marketplace.
```
const fs = require('fs');
if (process.argv.length < 3) {
throw new Error('Expected a file containing a list of native modules as the third param');
}
function read(filename) {
return fs.readFileSync(filename, 'utf8');
}
const nativeModuleFilenames = read(process.argv[2]).split('\n').filter(Boolean);
nativeModuleFilenames.forEach((fileName) => {
if (fileName.endsWith('.h')) {
return;
}
const absPath = `${process.env.HOME}/${fileName}`;
const fileSource = read(absPath);
if (/(\n|^)-\s*\((.+)\)getConstants/.test(fileSource)) {
return;
}
const constantsToExportRegex = /(\n|^)-\s*\((.+)\)constantsToExport/;
const result = constantsToExportRegex.exec(fileSource);
if (result == null) {
throw new Error(`Didn't find a constantsToExport function inside NativeModule ${fileName}`);
}
const returnType = result[2];
const newFileSource = fileSource.replace(
constantsToExportRegex,
'$1- ($2)constantsToExport\n' +
'{\n' +
` return ${returnType.includes('ModuleConstants') ? '($2)' : ''}[self getConstants];\n` +
'}\n' +
'\n' +
'- ($2)getConstants'
);
fs.writeFileSync(absPath, newFileSource);
});
```
```
> xbgs -l ')constantsToExport'
```
