问题：  ( !isDir(sprintf(config_file "%s_shared\\post_process" config_file)) 中，
这个config_file。。。。。。。。。。。config_file 最后的路径是啥？帮忙贴一下，为啥前后都有config_file变量

完整参考片段：
procedure( ppra_read_gerber_config()
let( (fin line film_def cmp usage key name mod_inc params layers config_file ret)

ret = nil

; location of shared library files
config_file = getShellEnvVar("allegroLIB_DIR");

; see if environment variable was set
if( !config_file then
    axlUIConfirm("[ALLEGROLIB_DIR] environment variable not set!")

    ; see if shared post-process location exists
else if( !isDir(sprintf(config_file "%s_shared\\post_process" config_file)) then
    axlUIConfirm(sprintf(nil "[%s] library directory does not exist!" config_file))

    ; see if gerber.cfg file exists
else if( !isFile(sprintf(config_file "%s\\gerber.cfg" config_file)) then
    axlUIConfirm(sprintf(nil "[%s] does not exist!" config_file))

    ; open the file
else if( (fin = axlDMOpenFile("TEMP" config_file "r")) == nil then
axlUIConfirm(sprintf(nil "[%s] Cannot open file!" config_file))

else
; read the file
while( (film_def = lineread(fin))

; if film_def = t, then it is a blank line
;if( (film_def != t) && (!nindex(film_def ";")) then
if( film_def != t then

key    = nth(0 film_def)
name = substring(key 3) ; remove usage prefix
usage = substring(key 1 1)
mod_inc = nth(1 film_def)
params  = nth(2 film_def)
layers  = nth(3 film_def)
PPRA_GERBER_FILMS[key] = make_PPRA_FILM_DATA(?usage usage ?name name ?mod_inc mod_inc ?params params ?layers layers)
)
)
axlDMClose(fin)
ret = t
))))
ret
))

另外%s 代表啥？ 见笑了，我是小白

就跟a=a+1的意思差不多，获取它的值，处理，再赋给它。%s表示printf里面的字符串类型。有点c基础的应该知道%d表示十进制数字。

%s 字符串变量
%d 整数变量
%f 小数变量
%L List类型的变量
.......
这些在Skill里，进行格式化的时候，经常用到。可以了解下

太感谢了????
