tent upgrade

Rewrites a project for the breaking changes of a newer major version, which come with the version that makes them. Within one major version nothing needs it: every project keeps working.

Usage

tent upgrade

Example

tent upgrade --json

It reads the line the project stands on from engines.tentjs of its package.json, records a point of the history, runs each step from that line to the one of the framework that runs over the project's files (the tent of the install, the newest installed, and never the older tentjs that the project holds, which knows no step to the newer line), records a point after them, and runs the check. What changed is printed as tent history compare prints it, so tent history back takes it back. With no step for the line of the project it says so, changes nothing, and ends with 0.

Output

With --json, the two lines, the steps that ran, the changes and what the check found:

{ "ok": true, "value": { "from": "1.9", "to": "2.0", "steps": ["oldTitle is title"], "changes": ["file tent.ts: changed"], "findings": [] }, "findings": [] }

With no step, steps is empty and said says so.

Errors

An error of the check over the upgraded project is printed as a finding, and the command ends with 1.
