Auto migrating script

[waltoss]

I love GenAIScript it's opening a whole possibility of scripting that we could never dream of years ago !

I am trying to write a script that do automatic package migration. My idea is to analyse dependabot pull requests, and using a GenAIScript to commit automatically code changes on that PR

Here is my first try to upgrade a package, for instance react-native-adjust from v4 to v5

// migration.genai.mjs
import TurndownService from "turndown";
import TurndownPluginGFM from "turndown-plugin-gfm";
import * as cheerio from "cheerio";

script({
    maxTokens: 32*1024,
    model: "openai:gpt-4o",
    system: ["system", "system.files", "system.typescript", "system.fs_find_files", "system.fs_read_file"],
})

// Retrieve migration guide
let { text } = await fetchText("https://dev.adjust.com/en/sdk/migration/react-native/v4-to-v5");

// Convert it to markdown
const selector = cheerio.load(text);
text = selector(".article-content").html();
var turndownService = new TurndownService().use(TurndownPluginGFM.gfm);
text = turndownService.turndown(text);

def("MIGRATION_GUIDE", text);

// Prompt
$`Your task is to migrate react-native-adjust from v4.38.1 to v5.0.0.
You will follow MIGRATION_GUIDE
You can search files that need to be changed

Some guidelines
- search only for needed files
- ignore files listed in .gitignore
- ignore content in messages.js : these are translations`

Then I run it like this

npx --yes genaiscript@latest run migration --apply-edits

However when I run it, the prompt, and intention are correct :

The react-native-adjust package is used in the src/shared/infra/analytics/adjust/adjust.ts file. This file contains initialization and event tracking logic that needs to be updated to comply with the SDK v5 changes as outlined in the migration guide.

Let's update the adjust.ts file to meet the requirements of SDK v5.0.0.

File src/shared/infra/analytics/adjust/adjust.ts:

import { Adjust as RNAdjust, AdjustConfig, AdjustEvent } from "react-native-adjust";

import { ADJUST_EVENT_TOKENS } from "#shared/infra/analytics/adjust/adjustEventTokens";
import type { AnalyticsEvent } from "#shared/infra/analytics/events.type";
import { appEnv } from "#shared/infra/appEnv";

export const Adjust = {
  init: () => {
    const adjustConfig = new AdjustConfig(
      appEnv.adjustToken,
      appEnv.adjustShouldUseProdEnv
        ? AdjustConfig.EnvironmentProduction
        : AdjustConfig.EnvironmentSandbox
    );
    RNAdjust.initSdk(adjustConfig); // Changed from create to initSdk
  },
  cleanUp: () => {
    RNAdjust.componentWillUnmount();
  },
  logEvent: (event: AnalyticsEvent) => {
    const adjustEvent = new AdjustEvent(ADJUST_EVENT_TOKENS[event]);
    RNAdjust.trackEvent(adjustEvent);
  },
};

Make sure to update your package.json to reflect the new version of react-native-adjust:

"dependencies": {
  "react-native-adjust": "^5.0.0"
}

Run npm install to update the dependency and apply the changes.

But no changes are made. Do you know what I did wrong ?

very cool... since these updates are small, you could try to swap system.files with system.changelog which will create diffs.

But otherwise this looks good. The edit should have been applied. I will debug this Monday.

There's also a way to ignore more files by default (on top of .gitignore)

Found way to fix it, I had to specify a file output to make --apply-edits work.

defFileOutput("**", "Any generated files by migration");

I found it by debugging

// fileedits.ts
export async function writeFileEdits(...) {
    for (const fileEdit of Object.entries(fileEdits || {})) {
        // Destructure the filename, before content, after content, and validation from the entry
        const [fn, { before, after, validation }] = fileEdit

        if (!validation?.valid) continue // ❌ valid was undefined

// promptrunner.ts
function validateFileOutputs(...) {
if (fileOutputs?.length && Object.keys(fileEdits || {}).length) { // ❌ fileOutputs was empty
...
}

I don't know if it's intended, but I didn't see it in documentation

[pelikhan]

ha! It should be valid !== false and some logging

[pelikhan]

fixed at c19e6fe

Btw, if you are looking at github actions build and log, you can look at the builtin "github" object which has a bunch of helpers, including giving the octokit object if you need to dig deeper.
