Typescript 0.8.3.1 Compile-On-Save degraded and stopped working today

Question

Visual Studio 2012, Typescript 0.8.3.1 Yesterday, I started having problem where, when I saved 1 .ts file, it would show me errors (about 6 in 3 files because they relied on the change I had just done), when I saved one of the other files that I went to fix the error it would none of the errors (even if I didn't fix).

When I rebooted, for the first 3 or 4 minutes, it showed no errors, but then 'suddenly' doing a save by adding and removing a space, the errors showed up, but then when I made a 'real' change, the js file did not change.

I can make any change I want and the js only changes if I exit VS and come back in, and when it reloads (I've tried this a few times) the js file is sometimes several changes out of date from the ts file, sometimes is based on the newest ts file.

I uninstalled the ts plugin and web essentials this morning and reinstalled (still 0.8.3.1).

No differences that I can see to the symptoms.

I have verified that both Visual Studio settings in Tools > Options > Text Editor > TypeScript > Project > Compile on Save settings are Unchecked and that the Webessentials one IS checked to compile on save.

There are no 'new' files and the only changes I've made in the past few days other than those noted above are to edit my existing ts files. Yesterday it appeared to be working fine until these anomalies started to occur.

Answer 1

The issue you are describing sounds like either...

• A genuine bug in your code that isn't getting shown immediately

• A problem with the state of the incremental editor

If it is the latter, there are improvements coming in newer versions. If you need help checking for code problems you'll need to share the code or a cut down example that demos the problem.
