Make / makefile进度指示！

标签： scripting makefile build-automation progress-bar

看看这个makefile，它有一些原始进度指示（可能是进度条）。

请给我建议/意见！ 


# BUILD is initially undefined
ifndef BUILD

# max equals 256 x's
sixteen := x x x x x x x x x x x x x x x x
MAX := $(foreach x,$(sixteen),$(sixteen))

# T estimates how many targets we are building by replacing BUILD with a special string
T := $(shell $(MAKE) -nrRf $(firstword $(MAKEFILE_LIST)) $(MAKECMDGOALS) \
            BUILD="COUNTTHIS" | grep -c "COUNTTHIS")

# N is the number of pending targets in base 1, well in fact, base x :-)
N := $(wordlist 1,$T,$(MAX))

# auto-decrementing counter that returns the number of pending targets in base 10
counter = $(words $N)$(eval N := $(wordlist 2,$(words $N),$N))

# BUILD is now defined to show the progress, this also avoids redefining T in loop
BUILD = @echo $(counter) of $(T)
endif

# dummy phony targets

.PHONY: all clean

all: target
    @echo done

clean:
    @rm -f target *.c

# dummy build rules

target: a.c b.c c.c d.c e.c f.c g.c
    @touch $@
    $(BUILD)

%.c:
    @touch $@
    $(BUILD)

欢迎所有建议！

这个更少侵入性和更棒。

ifneq ($(words $(MAKECMDGOALS)),1)
.DEFAULT_GOAL = all
%:
        @$(MAKE) $@ --no-print-directory -rRf $(firstword $(MAKEFILE_LIST))
else
ifndef ECHO
T := $(shell $(MAKE) $(MAKECMDGOALS) --no-print-directory \
      -nrRf $(firstword $(MAKEFILE_LIST)) \
      ECHO="COUNTTHIS" | grep -c "COUNTTHIS")

N := x
C = $(words $N)$(eval N := x $N)
ECHO = echo "`expr " [\`expr $C '*' 100 / $T\`" : '.*\(....\)$$'`%]"
endif

.PHONY: all clean

all: target
        @$(ECHO) All done

clean:
        @rm -f target *.c
#       @$(ECHO) Clean done

target: a.c b.c c.c d.c e.c
        @$(ECHO) Linking $@
        @sleep 0.1
        @touch $@

%.c:
        @$(ECHO) Compiling $@
        @sleep 0.1
        @touch $@

endif

这是对@ GiovanniFunchal优秀answer的略微修改。

所以我想更好地理解这一点并让它适用于＆lt; 10％所以我挖掘了documentation并了解了更多关于expr的内容。

# PLACE AT THE TOP OF YOUR MAKEFILE
#---------------------------------
# Progress bar defs
#--------------------------------
#  words = count the number of words
ifneq ($(words $(MAKECMDGOALS)),1) # if no argument was given to make...
.DEFAULT_GOAL = all # set the default goal to all
#  http://www.gnu.org/software/make/manual/make.html
#  $@ = target name
#  %: = last resort recipe
#  --no-print-directory = don't print enter/leave messages for each output grouping
#  MAKEFILE_LIST = has a list of all the parsed Makefiles that can be found *.mk, Makefile, etc
#  -n = dry run, just print the recipes
#  -r = no builtin rules, disables implicit rules
#  -R = no builtin variables, disables implicit variables
#  -f = specify the name of the Makefile
%:                   # define a last resort default rule
      @$(MAKE) $@ --no-print-directory -rRf $(firstword $(MAKEFILE_LIST)) # recursive make call, 
else
ifndef ECHO
#  execute a dry run of make, defining echo beforehand, and count all the instances of "COUNTTHIS"
T := $(shell $(MAKE) $(MAKECMDGOALS) --no-print-directory \
      -nrRf $(firstword $(MAKEFILE_LIST)) \
      ECHO="COUNTTHIS" | grep -c "COUNTTHIS")
#  eval = evaluate the text and read the results as makefile commands
N := x
#  Recursively expand C for each instance of ECHO to count more x's
C = $(words $N)$(eval N := x $N)
#  Multipy the count of x's by 100, and divide by the count of "COUNTTHIS"
#  Followed by a percent sign
#  And wrap it all in square brackets
ECHO = echo -ne "\r [`expr $C '*' 100 / $T`%]"
endif
#------------------
# end progress bar
#------------------

# REST OF YOUR MAKEFILE HERE

#----- Progressbar endif at end Makefile
endif

我摆脱了: '.*\(....\)$$'部分。它将返回内部expr命令的最后4个字符，但如果它小于4则会失败。现在它适用于10％以下！

以下是评论免费版：

ifneq ($(words $(MAKECMDGOALS)),1) # if no argument was given to make...
.DEFAULT_GOAL = all # set the default goal to all
%:                   # define a last resort default rule
      @$(MAKE) $@ --no-print-directory -rRf $(firstword $(MAKEFILE_LIST)) # recursive make call, 
else
ifndef ECHO
T := $(shell $(MAKE) $(MAKECMDGOALS) --no-print-directory \
      -nrRf $(firstword $(MAKEFILE_LIST)) \
      ECHO="COUNTTHIS" | grep -c "COUNTTHIS")
N := x
C = $(words $N)$(eval N := x $N)
ECHO = echo -ne "\r [`expr $C '*' 100 / $T`%]"
endif

# ...

endif

希望有所帮助。

答案 2 :(得分：3)

非常感谢@Giovanni Funchal和@phyatt的问题和答案！

为了我自己更好的理解，我进一步简化了它。

ifndef ECHO
HIT_TOTAL != ${MAKE} ${MAKECMDGOALS} --dry-run ECHO="HIT_MARK" | grep -c "HIT_MARK"
HIT_COUNT = $(eval HIT_N != expr ${HIT_N} + 1)${HIT_N}
ECHO = echo "[`expr ${HIT_COUNT} '*' 100 / ${HIT_TOTAL}`%]"
endif
  • !=从shell命令分配
  • =每次使用变量时都会对其求值
  • eval执行其参数而没有任何输出
  • expr允许进行算术计算

（不知道哪种方法更快：用expr调用shell或用make计数'x'-es。）

用法相同：

target:
    @$(ECHO) $@

好戏！ （ - ：

但对于分布在具有大量makefile的许多目录中的增长项目而言，并不是真正可扩展。

我更倾向于在项目中通过[Mm] akefiles *进行日志记录，并使用它来跟踪进度。

只是一个想法。 BTW感谢您分享此内容。

编辑：刚想了想。这可能在修改的形式中有用，以显示在长任务进行时显示进度的跳动，例如解压缩大型分发tarball而不是仅指定tar命令的-v选项。还有一点糖衣，但也有点乐趣。 （ - ：

欢呼声，

并没有真正的问题，因此这不是一个独立的答案，而是对Giovanni Funchai的solution的扩展。这个问题是“ GNU取得进步”的第一个Google搜索结果，因此我在这里寻找如何做到这一点。

正如Rob Wells所指出的那样，该解决方案在<10％的情况下不起作用，但是该技术可以通过辅助脚本以您认为足够可移植的任何语言进行打印格式扩展。例如，使用python帮助程序脚本：

echo_progress.py：

"""
Print makefile progress
"""

import argparse
import math
import sys

def main():
  parser = argparse.ArgumentParser(description=__doc__)
  parser.add_argument("--stepno", type=int, required=True)
  parser.add_argument("--nsteps", type=int, required=True)
  parser.add_argument("remainder", nargs=argparse.REMAINDER)
  args = parser.parse_args()

  nchars = int(math.log(args.nsteps, 10)) + 1
  fmt_str = "[{:Xd}/{:Xd}]({:6.2f}%)".replace("X", str(nchars))
  progress = 100 * args.stepno / args.nsteps
  sys.stdout.write(fmt_str.format(args.stepno, args.nsteps, progress))
  for item in args.remainder:
    sys.stdout.write(" ")
    sys.stdout.write(item)
  sys.stdout.write("\n")

if __name__ == "__main__":
  main()

修改后的Makefile：

_mkfile_path := $(abspath $(lastword $(MAKEFILE_LIST)))
I := $(patsubst %/,%,$(dir $(_mkfile_path)))

ifneq ($(words $(MAKECMDGOALS)),1)
.DEFAULT_GOAL = all
%:
    @$(MAKE) $@ --no-print-directory -rRf $(firstword $(MAKEFILE_LIST))
else
ifndef ECHO
T := $(shell $(MAKE) $(MAKECMDGOALS) --no-print-directory \
      -nrRf $(firstword $(MAKEFILE_LIST)) \
      ECHO="COUNTTHIS" | grep -c "COUNTTHIS")
N := x
C = $(words $N)$(eval N := x $N)
ECHO = python $(I)/echo_progress.py --stepno=$C --nsteps=$T
endif

.PHONY: all clean

all: target
    @$(ECHO) All done

clean:
    @rm -f target *.c
#       @$(ECHO) Clean done

target: a.c b.c c.c d.c e.c f.c g.c h.c i.c j.c k.c l.c m.c n.c o.c p.c q.c \
        r.c s.c t.c u.c v.c w.c x.c y.c z.c
    @$(ECHO) Linking $@
    @sleep 0.01
    @touch $@

%.c:
    @$(ECHO) Compiling $@
    @sleep 0.01
    @touch $@

endif

产量：

$ make
[ 1/28](  3.57%) Compiling a.c
[ 2/28](  7.14%) Compiling b.c
[ 3/28]( 10.71%) Compiling c.c

[22/28]( 78.57%) Compiling v.c
[23/28]( 82.14%) Compiling w.c
[24/28]( 85.71%) Compiling x.c
[25/28]( 89.29%) Compiling y.c
[26/28]( 92.86%) Compiling z.c
[27/28]( 96.43%) Linking target
[28/28](100.00%) All done

甚至可以打印带有Unicode字符的精美进度条。

修改后的echo_progress.py：

"""
Print makefile progress
"""

import argparse
import math
import sys

def get_progress_bar(numchars, fraction=None, percent=None):
  """
  Return a high resolution unicode progress bar
  """
  if percent is not None:
    fraction = percent / 100.0

  if fraction >= 1.0:
    return "█" * numchars

  blocks = [" ", "▏", "▎", "▍", "▌", "▋", "▊", "▉", "█"]
  length_in_chars = fraction * numchars
  n_full = int(length_in_chars)
  i_partial = int(8 * (length_in_chars - n_full))
  n_empty = max(numchars - n_full - 1, 0)
  return ("█" * n_full) + blocks[i_partial] + (" " * n_empty)

def main():
  parser = argparse.ArgumentParser(description=__doc__)
  parser.add_argument("--stepno", type=int, required=True)
  parser.add_argument("--nsteps", type=int, required=True)
  parser.add_argument("remainder", nargs=argparse.REMAINDER)
  args = parser.parse_args()

  nchars = int(math.log(args.nsteps, 10)) + 1
  fmt_str = "\r[{:Xd}/{:Xd}]({:6.2f}%) ".replace("X", str(nchars))
  progress = 100 * args.stepno / args.nsteps
  sys.stdout.write(fmt_str.format(args.stepno, args.nsteps, progress))
  sys.stdout.write(get_progress_bar(20, percent=progress))
  remainder_str = " ".join(args.remainder)
  sys.stdout.write(" {:20s}".format(remainder_str[:20]))
  if args.stepno == args.nsteps:
    sys.stdout.write("\n")

if __name__ == "__main__":
  main()

这将导致如下结果：

$ make clean && make
[12/28]( 42.86%) ███████▊             Compiling k.c

在进展中，并且：

$ make clean && make
[28/28](100.00%) ████████████████████ All done

完成后。
