About the snippet plugin¶

This plugin is designed to work with simple VIM snippets like the once from here The plugin itself doesn't provide any snippets. To add snippets for a language place a file containing the snippets at ~/.config/micro/plugins/snippets/[filetype].snippets

Commands¶

The plugin provides the following commands:

Command	Description of function	Key
snippetinsert	with an optional parameter to specify which snippet	Alt+S
'	should be inserted.
'	If the parameter is absent, the word right
'	before the cursor will be used for this.
snippetnext	proceeds to the next placeholder	Alt+W
snippetcancel	removes all the current snippet	Alt+D
snippetaccept	finishes the snippet editing for the current snippet	Alt+A

Snippet Files¶

The snippet files have a very simple syntax:

lines starting with # are ignored
a line starts with snippet starts a new snippet.
after snippet you can add one or more shortcuts for the snippets, like snippet aFunc bFunc (at least one shortcut is required)
every line of code within the snippet must start with a tab (\t)
a snippet can have multiple placeholders which are indicated by ${num[:name]} where num is a numeric value. Placeholders with the same number share the same value. You also have the option to give a placeholder a name / description / default value.

Plugins can provide snippet files they just need to publish them as a runtime file with type snippets. See the plugins help for additional details.

Sample for go:

# creates a function that prints a value
snippet fmtfunc
    func ${0:name}() {
         fmt.Println("${0} prints:", ${1:value})
    }

Custom Key Bindings¶

Add a file, if not already created in ~/.config/micro/bindings.json

Change the default keys you want to use.

Micro editor as a help file here https://github.com/zyedidia/micro/blob/master/runtime/help/keybindings.md

{
"Alt-w": "snippets.Next",
"Alt-a": "snippets.Accept",
"Alt-s": "snippets.Insert",
"Alt-d": "snippets.Cancel"
}

Raw key codes¶

Micro has a command raw

Micro will open a new tab and show the escape sequence for every event it receives from the terminal.

This shows you what micro actually sees from the terminal and helps you see which bindings aren't possible and why.

This is most useful for debugging keybindings.

Example

\x1b turns into \u001 then the same as the raw output.

"\u001bctrlback": "DeleteWordLeft"
