Hi Gorkem,
Here some information I would like to tell you:
* JavaScript Debugger. It should be very cool if someone could
implement a
debuger for tern.java to debug ternjs like Webclipse and Nodeclipse
have
done
https://github.com/angelozerr/tern.java/tree/master/eclipse/debuggers.
This feature is soon finished and it gives you the capability to debug
ternjs en your custom tern plugin with Eclipse IDE. You select the
debugger
you wish with a tern.java NodeJS preferences, you set a breakpoint in
the
tern.js file (ex: where completion is executed). You open a JS editor
and
you do Ctrl+Space and debugger stops to the breakpoint. So now it's
very
easy to debug ternjs with Eclipse IDE.
* TypeScript Langage Service. I have studied that at first by playing
with
:
* http://typecsdev.com/
* https://github.com/palantir/eclipse-typescript
And I find there are a big problem with performance: my Eclipse
freezes
soon.
I have noticed the freeze as well but it is not due to typescript
compiler
but more of an issue on how it is used with eclipse.
The attractive points on typescript compiler was it actually provides
a bunch of services for IDEs that could allow us to replace the
corresponding outdated JSDT ones. Also the number of type definition
libraries is very extensive for typescript.
Anyhow, this was a quick experimentation on my part and I am not
convinced
it is the way forward
To be honnest with you, I don't understand what you mean with "Can be
used
as an alternate to tern.js". TypeScript needs to declare variable with
type
(ex: var p: Person) although JavaScript needs not that and ternjs is
able
to guess the type.
Agreed. typescript compiler does not seem to provide inference in this
case. It relies on
modules and module definitions.
In my side, I have started to study how we could support
Angular2 which is based on TypeScript
https://github.com/angelozerr/angularjs-eclipse/issues/164 and I have
several ideas to support TypeScript with tern.java:
* TypeScript provides a tsserver which uses TypeScript Language
Service.
It works with "readline" and not with "http" (tern.java works only
with
"http").
What is the advantage of http over readLine?
My first idea is to use TypeScript Language Service inside
tern.java by customizing JSON request/response of tsserver to adapt it
for
ternjs. See project https://github.com/angelozerr/tern-tsserver What
is the
benefit with existing Eclipse TypeScript plugins: the async completion
of
tern.java
https://github.com/angelozerr/tern.java/wiki/New-and-Noteworthy-0.9.0#async-tern-completion
which avoid freezing Eclipse.
* my second idea (my prefered idea, but which is hard) is to implement
an
acorn plugin for TypeScript like
https://github.com/RReverser/acorn-jsx
have done for JSX. I have started at
https://github.com/angelozerr/tern-typescript/blob/master/acorn-ts.js
.
Today I can support declaration type like (var a: Person). The benefit
with
that is that we will able to use tern plugins features to customize
completion for Angular2.
This is probably the case that I would like JSDT to support better. I
hope we can replace the JSDT parser with a pluggable one like acorn. I
know that there is an interest to extend JSDT to things like QML as well
so
a pluggable parser will help.
Another advantage of this approach will be the AST can be shared among
tools avoiding
extra parsing. ESTree seems to be the de-factor standard for JavaScript
AST, it would
be grand if we can support ESTree natively on JSDT so that it is shared
among libraries/tools and
avoiding repeated parsing.
