Go

cycle_by_var_name(identifiers=[])

Will get identifier under cursor and either complete it to the full variable name from previous code in file, or substitute identifier with previous variable declaration

Usage with UltiSnips

In go.snippets:

snippet i "if "
if ${1:`!p snip.rv=go.get_last_var_for_snippet()`} {
        ${2:${VISUAL}}
}
endsnippet

In .vimrc:

au FileType go inoremap <C-L> <C-\><C-O>:py go.cycle_by_var_name()<CR>
au FileType go smap <C-L> <BS><C-L>

i will expand into if with last used variable as condition. Use <C-L> to select previous variables.

extract_prev_method_binding_for_cursor()

Returns binded variable name and type name for inserting into method declarations:

func (someVar TypeForSomeVar) MethodName() {
    // come code
}

Method will deduce tuple (someVar TypeForSomeVar) from either previous method declaration or type declaration.

Usage with UltiSnips

In go.snippets:

snippet d "define method"
func (`!p snip.rv=' '.join(go.extract_prev_method_binding_for_cursor())`) $1($2) $3${3/.+/ /}{
        $4
}
endsnippet

snippet dp "define method on pointer"
func (`!p snip.rv=' *'.join(go.extract_prev_method_binding_for_cursor())`) $1($2) $3${3/.+/ /}{
        $4
}
endsnippet

guess_package_name_from_file_name(path)

Return basename part of the path for using as new package name.

get_previous_slice_usage()

Returns previous used slice name.

split_parenthesis()

Split line in parenthesis into multiple lines.

TBD: gif

get_last_var_for_snippet()

Same, asd cycle_by_var_name, but for using in snippet.

get_last_used_var(prev_var='', identifiers=[])

Filter identifiers list and return first variable. If prev_var is specified, then identifier list will be scanned either for exact match for prev_var, and then return variable that came just before; if prev_var is matching prefix for some var, then return value will be completed value.

get_all_last_used_identifiers()

Return list of identifiers that are looks like variables.

get_last_defined_identifiers()

Return list of identifiers that are looks like just declared using :=, = or passed via arguments.

get_identifier_under_cursor()

Return identifier under cursor.

get_imports()

Return imports list with package names from current file.

path_to_import_name(path)

Return package name from import name.

get_package_name_from_file(path)

Return package name from specified file.
