less - LessCss - extending css on the fly -

-

i aware of can declare class : 

.someclass { ... }

and extend it

.otherclass { &:extend(.someclass all) }

but .someclass has declared ?

in case callers apply logic , there no need someclass have logic declared well, placeholder similar css.

it nice if there &:extend(groupingfunction all) .

but maybe there already?

currently less don't support "placeholder-equivalent".

checkout issue: :extend mixins.

you can use "@import (reference)" feature "simulate" behavior can cause unexpected problems in cases (there quite few issues import reference feature).

what isshellcommand property , how should use it? the description when hovering says: "specifies whether command shell command or external programm. defaults false if omitted" and in https://code.visualstudio.com/docs/editor/tasks mention in example with: "we want run gulp command in shell (vs code directly executing it) used isshellcommand" so difference between shell command vs external program? does running isshellcommand = false mean vscode not "directly executing it" meaning run "command" , don´t listen output (because ran external command?) in turn means cannot use problem matchers. or if setting isshellcommand = true mean vscode "directly executing it" , keep track of , listen output generated can use problem matchers etc integrate vscode? considering example below using tsc compile typescript project: c:\users\j\code\vscode-project>where tsc c:\program files (x86)\microsoft sdks\typescript\1.4\tsc.exe ...
