Question

如何从指挥线向马克茨提出论据?

I understand I can do

$ make action VAR="value"
$ value

www.un.org/spanish/ecosoc

VAR = "default"
action:
    @echo $(VAR)

我如何得到以下行为?

$ make action value
value

如何

$make action value1 value2
value1 value2

Answer 1

你也许不这样做;你重开如何发挥作用的基本模式。但这里的是:

action:
        @echo action $(filter-out $@,$(MAKECMDGOALS))

%:      # thanks to chakrit
    @:    # thanks to William Pursell

EDIT:
To explain the first command,

$(MAKECMDGOALS) is the list of “targets” specified on the control line, e.g. “action Value1 Value2”.

automatic,用于该规则目标的名称,此处为“action”。

<代码>filter-out是一种功能,从名单中删除一些内容。 ∗∗∗∗∗∗∗∗∗∗ (它可能更微妙,但在此我们不需要微妙。)

这些数字加在一起,$ (filter-out$@,$ (MAKECMDGOALS)回到除“action”外的指挥线上列明的目标清单,该清单可能“价值1” 。

Answer 2

Here is a generic working solution based on @Beta s

I m using GNUMak 4.1 with SHELL=/bin/bash atop myMakfile, so YMMV!

This allows us to accept extra arguments (by doing nothing when we get a job that doesn t match, rather than throwing an error).

%:
    @:

这是一项给我们带来动力的宏观:

args = `arg="$(filter-out $@,$(MAKECMDGOALS))" && echo $${arg:-${1}}`

Here is a job which might call this one:

test:
    @echo $(call args,defaultstring)

结果是:

$ make test
defaultstring
$ make test hi
hi

Note! You might be better off using a "Taskfile", which is a bash pattern that works similarly to make, only without the nuances of Maketools. See https://github.com/adriancooney/Taskfile

Answer 3

更为容易。考虑一项任务:

provision:
        ansible-playbook -vvvv 
        -i .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory 
        --private-key=.vagrant/machines/default/virtualbox/private_key 
        --start-at-task="$(AT)" 
        -u vagrant playbook.yml

我现在要说的话,我只是说:

<条码>AT=“造型资产”

或者说:

<编码>make provision in this case AT is an food string

Answer 4

几年后,希望就此建议<代码>just:。

action v1 v2=default:
    @echo  take action on {{v1}} and {{v2}}...

Answer 5

You will be better of defining variables and calling your make instead of using parameters:

文件

action: ## My action helper
    @echo $$VAR_NAME

终端站

> VAR_NAME="Hello World" make action
Hello World

Answer 6

不要试图这样做

$ make action value1 value2

而是用文字:

#! /bin/sh
# rebuild if necessary
make
# do action with arguments
action "$@"

并且:

$ ./buildthenaction.sh value1 value2
