Suggestion qtc: Add a watcher qtc -w

[ghost]

Add a watcher subcommand/flag for example qtc -w ./ -d ./templates -> watch and compile on file changes in the current directory, serve the compiled files in the ./templates directory.

You can use fsnotify package, I will do that on iris but it will be nice to have it build'n with qtc :)

P.S: I don't know if go generate has a watch command but I doubt

I'm not sure how this would work. Quicktemplate only creates *.go files by running go generate. You could automate that with fsnotify but then you also have to recompile the whole application right?

This requires recompilation of the whole application. I doubt qtc is a good level for such a functionality. Probably a separate watcher app may be created instead for automatic recompilation on template files' modifications.

@valyala Yes, this is a problem with most of the good Go templating engines, except the ones that don't generate source code (like Jet). Every time you make the smallest change in any template, you have to run go generate and then recompile the whole app. I looked at Jet, but it uses reflection, which I hate. Would you consider adding basic include, for-each and if-then functionality to Fasttemplate? That's all we really need.

Yes, you're right , the whole application needs to be re-compiled... I'm closing this issue and sorry I should know that

I don't want complicating fasttemplate. So it would be better just using Jet. It looks like it is the fastest template engine for go at the moment, which doesn't require source code recompilation after each modification.

modd is a nice tool I just found to handle this.

Here is my modd.conf file for quicktemplate:

**/*.qtpl {
    prep: qtc
}

**/*.go {
    prep: go build -o devbuild
    daemon: ./devbuild
}

devbuild {
    daemon: devd --livewatch --modd http://localhost:8080
}

With this setup changing a single .qtpl file will recompile everything and restart the server.

The last part at the bottom uses devd from the same author to work with livereload. That part can be removed if you don't want livereload.

@stereosteve , this is awesome!

@valyala thanks for quicktemplate! It is so much better than text/template. If I could double star it I would.
