Little and fast web-development library for Golang

clio's Issues

Sometimes process relaunches not correctly

In some cases after *.go or *.template file update

app  panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x0 pc=0x2472e]

Move clio-hotswap into clio's main package

Move dependencies out

Support for namespaces in generators

clio g s admin/users

Create adapter for UI generators from clio

App creator

Clio should have possibility to create an app skeleton from command line with, for example, clio create new_app command

Assets support

Sexy and informative "Welcome aboard" page

Reporting errors to Errbit and Airbrake

Sending error reports to a named serviced. What need to be done:

• Error reporting API
• Plugin for sending reports
• Data for Integration (api key etc) in application's settings.

Requirements:

• Sending error should be non-blocking (sending error reports in a background)

Update documentation

Move back to `routes.Resources ()` invocation of resource's routes

• additionally we need to add line with routes.Resources () to application.go during generation of a new scaffold / route

WebSockets

Ws ("path/of/channel")

Generators

Load view templates using absolute paths

App Settings should be accessible from all Core package

404

Workers

Clio should have possibility to manage (run and watch) helper processes, defined in config/procfile

Managing dependencies

Make possible to install dependencies, declared in config/dependencies file with go get

Make `clio watch` verbose

This linked with #43

"Welcome aboard" page

New design and markup for root page in freshly created application.

`app error occured: exec: "./application": stat ./application: no such file or directory`

On first application start up:

2013/09/26 15:46:30 Building application binary
 app  error occured: exec: "./application": stat ./application: no such file or directory

Resource mapping

Looks unuseful:
func ControllerRoutes () {
Get ("/books", Books )
Get ("/books/", Book )
Post ("/books", BooksCreate)
Put ("/books/", BookUpdate )
Delete ("/books", BooksRemove)
Delete ("/books/*", BookRemove )
}

I think it will be better something like that:

func ControllerRoutes () {
Resourse ("books", Books )
}

Make clio safely work with GOPATH

Strange bug according local packages appears on newest versions of Golang.
So we need to make Clio play with GOPATH nicely.

• make sure that application is located inside GOPATH
• change local packages calls in application's template and generated files to absolute ones, starting from application's root (for example ./routes should be changed to application/routes)

Any other system processes (for example daemons or workers) can send messages to certain WebSocket channel through RPC

For example using send(route, message string) API call

Error handling, debugging and testing

Methods to give away JSON content

Clio should have JSONGet () method, which receives same arguments, as Get () methods but give away content in application/json format without any layouts.

Use GOPATH + app name during running generators

Redirects

Add Redirect (to string) function to core API

Error during start up a freshly builded application

2013/10/02 15:32:56 open /Users/sergey/Desktop/library/tmp/pids/clio.pid: no such file or directory

Form data processing

Proxy

Proxy for reloading back binary without missing connections

Simplify generation of an application from template

clio run

clio run
2013/08/12 22:40:38 Building application binary
app error occured: exec: "./application": stat ./application: no such file or directory

Use `init` instead of manual registering of remotes

Use GOROOT instead of GOPATH in path calculations

Improve messages in `clio run` mode

Not all messages of application process shows up in clio run mode. Thats not cool. Also there's no messages on application recompile and restart.

go run application.go

go run application.go
2013/08/12 22:38:38 open /var/folders/vp/vjytw_0x5937wrfqvxshy33h0000gp/T/go-build163112427/command-line-arguments/_obj/exe/tmp/pids/clio.pid: no such file or directory
exit status 1

Named parameters in splats

Verbose output turned off by default

...but should be turned on in application.go
Reason why we need this - exceed info during application's tests running.

Add tests to generated code

Hot swapping

Clio should have possibility to swap code without restarting main server. Main way to do this - is to use proxy.
Also swapping process should recognise unsuccessful code building and use previous version of app binary and show compile error message.

When I create new app and run it I can see it in browser

Steps for reproduce:

1. go get github.com/pallada/clio
2. clio create myapp:
   error: open /src/github.com/pallada/clio/templates/config/application.go: no such file or directory
   error: open /src/github.com/pallada/clio/templates/config/assets.yml: no such file or directory
   error: open /src/github.com/pallada/clio/templates/config/dependencies: no such file or directory
   error: open /src/github.com/pallada/clio/templates/config/procfile.yml: no such file or directory
   error: open /src/github.com/pallada/clio/templates/public/javascripts/vendor/underscore/underscore.js: no such file or directory
   error: open /src/github.com/pallada/clio/templates/public/javascripts/vendor/backbone/backbone.js: no such file or directory
3. clio run: nothing happen;

What the problem?

Need add clio version

it can help us and users. in future we can create change logs

Basic assets

Update `clio help`

Detect unsuccessful rebuild in hot-swap

We need to detect unsuccessful compilation, and not hot-swap in this case.

Add Security

CSRF attacks
Filter inputs
XSS attacks
SQL injection
Password storage
Encrypt and decrypt data

`clio version`

Templates in-memory caching

Simplify `clio run`

• Remove IPC from clio run
• Run application not as system process, but as go routine of clio run
• Kill and restart application without compilation, just using Go channels
• Built-in *.go and *.template file watching in clio run
• Define all watching-related settings as application's settings
