Lightweight Go IDE (with Debugging support)

Today I found that Visual Studio Code by Microsoft is quite charming, it based on Electron, library that being used to make Atom Editor (and Nuclide by Facebook). It loads fast, really fast. In ArchLinux or Manjaro, you can install it using this command:

yaourt -S visual-studio-code

After installing, type Ctrl+Shift+P, Install Extension, choose Go (Rich Go bla bla..). And yes, it requires internet connection.

Then install the tools required:

go get -u -v github.com/nsf/gocode
go get -u -v github.com/rogpeppe/godef
go get -u -v github.com/golang/lint/golint
go get -u -v github.com/lukehoban/go-find-references
go get -u -v github.com/lukehoban/go-outline
go get -u -v sourcegraph.com/sqs/goreturns
go get -u -v golang.org/x/tools/cmd/gorename
go get -u -v github.com/tpng/gopkgs
go get -u -v github.com/newhook/go-symbols

For debugging, install delve (it requires Go 1.5 or newer).

The import bulb will show if a package not yet imported:

The autocomplete just works as expected:

Argument tooltip (parameter info) shown correctly:

Jump to definition works (Ctrl+Click):

I believe this is better alternative (for now) than Atom, Brackets, LightTable, and LimeText (incomplete SublimeText implementation).

Atom vs Brackets vs LightTable vs Zed

Today we will review about some text editor that seems to be gaining popularity lately, that are Atom (Github), Brackets (Adobe), LightTable and Zed. To install them on ArchLinux, just type:

yaourt --needed --noconfirm -S --force brackets-bin atom-editor-bin lighttable zed slap

First one is Atom 1.0.2-1, it uses 131MB of RAM at the first run, the Javascript autocomplete seems not working.

The second one is Brackets 1.3-1, it uses 75MB of RAM at the first run, the Javascript autocomplete works fine.

The third one is LightTable 0.7.2-1, it uses 70MB of RAM at the first run, the Javascript autocomplete not as good as Bracket's..

The fourth one is Zed 1.1.0-1, it uses 54MB of RAM at the first run, there are no built-in Javascript autocomplete.

Bonus: Slap is terminal-based text-editor that aims to be similar to SublimeText. It uses 101MB of RAM at the first run, and the key shortcut (PgUp, PgDn, Up, Down) seems not working well. LimeText (currently broken: lime-git) also tried to be SublimeText clone.

The winner for now would be Brackets..
