This directory contains the typescript compiler and a small compiler host for

the runtime snapshot.

## How to upgrade TypeScript.
|
|
|
|
The files in this directory are mostly from the TypeScript repository. We
|
|
currently (unfortunately) have a rather manual process for upgrading TypeScript.
|
|
It works like this currently:
|
|
|
|
1. Checkout denoland/TypeScript repo in a separate directory.
|
|
1. Add Microsoft/TypeScript as a remote and fetch its latest tags
|
|
1. Checkout a new branch based on this tag.
|
|
1. Cherry pick the custom commit we made in a previous release to the new one.
|
|
1. This commit has a "deno.ts" file in it. Read the instructions in it.
|
|
1. Copy typescript.js into Deno repo.
|
|
1. Copy d.ts files into dts directory.
|
|
1. Review the copied files, removing and reverting what's necessary
|
|
|
|
So that might look something like this:
|
|
|
|
```
|
|
git clone https://github.com/denoland/TypeScript.git
|
|
cd typescript
|
|
git remote add upstream https://github.com/Microsoft/TypeScript
|
|
git fetch upstream
|
|
git checkout v3.9.7
|
|
git checkout -b branch_v3.9.7
|
|
git cherry pick <previous-release-branch-commit-we-did>
|
|
npm install
|
|
npx hereby
|
|
rsync built/local/typescript.js ~/src/deno/cli/tsc/00_typescript.js
|
|
rsync --exclude=protocol.d.ts --exclude=tsserverlibrary.d.ts --exclude=typescriptServices.d.ts built/local/*.d.ts ~/src/deno/cli/tsc/dts/
|
|
```
