我正在尝试按照文件名对罐子列表进行排序:
def jars = ['app-5.0.0.jar', 'app-5.1.1.jar', 'app-5.2.0-9.jar', 'app-5.2.0-10.jar', 'app-5.2.0.jar', 'app-5.1.0.jar']
jars = jars.sort().reverse()
println jars
结果是:
[app-5.2.0.jar, app-5.2.0-9.jar, app-5.2.0-10.jar, app-5.1.1.jar, app-5.1.0.jar, app-5.0.0.jar]
但是,我对自然(可能更直观)排序更感兴趣,以接收这个排序列表:
[app-5.2.0-10.jar, app-5.2.0-9.jar, app-5.2.0.jar, app-5.1.1.jar, app-5.1.0.jar, app-5.0.0.jar]
有没有办法实现这个目标?
这是我目前的排序算法,但在我看来它太冗长了。但是,它确实做了我正在寻找的东西。版本的每个部分(主要,次要,维护,构建)都是独立评估的:
jars = jars.sort { a, b ->
File fileA = new File(a)
File fileB = new File(b)
def partsA = fileA.name.findAll(/\d+/)
def partsB = fileB.name.findAll(/\d+/)
if (partsA[0] == null) partsA[0] = "0"
if (partsB[0] == null) partsB[0] = "0"
if (partsA[0].toInteger() < partsB[0].toInteger()) {
println "${partsA[0]} < ${partsB[0]}"
return -1
} else if (partsA[0].toInteger() > partsB[0].toInteger()) {
println "${partsA[0]} > ${partsB[0]}"
return 1
} else {
if (partsA[1] == null) partsA[1] = "0"
if (partsB[1] == null) partsB[1] = "0"
if (partsA[1].toInteger() < partsB[1].toInteger()) {
println "${partsA[1]} < ${partsB[1]}"
return -1
} else if (partsA[1].toInteger() > partsB[1].toInteger()) {
println "${partsA[1]} > ${partsB[1]}"
return 1
} else {
if (partsA[2] == null) partsA[2] = "0"
if (partsB[2] == null) partsB[2] = "0"
if (partsA[2].toInteger() < partsB[2].toInteger()) {
println "${partsA[2]} < ${partsB[2]}"
return -1
} else if (partsA[2].toInteger() > partsB[2].toInteger()) {
println "${partsA[2]} > ${partsB[2]}"
return 1
} else {
if (partsA[3] == null) partsA[3] = "0"
if (partsB[3] == null) partsB[3] = "0"
if (partsA[3].toInteger() < partsB[3].toInteger()) {
println "${partsA[3]} < ${partsB[3]}"
return -1
} else if (partsA[3].toInteger() > partsB[3].toInteger()) {
println "${partsA[3]} > ${partsB[3]}"
return 1
} else {
println "${partsA[3]} = ${partsB[3]}"
return 0
}
}
}
}
}
答案 0 :(得分:3)
不得不试试这个:
def jars = ['app-5.0.0.jar', 'app-5.1.1.jar', 'app-5.2.0-9.jar', 'app-5.2.0-10.jar', 'app-5.2.0.jar', 'app-5.1.0.jar', 'app-1.0.jar', 'app-0.10.jar']
jars = jars.sort{ -it.findAll( /\d+/ ).join().toInteger() }
println jars
获取:
[app-5.2.0-10.jar, app-5.2.0-9.jar, app-5.2.0.jar, app-5.1.1.jar, app-5.1.0.jar, app-5.0.0.jar, app-1.0.jar, app-0.10.jar]
或处理大型补丁版本的更全面的版本:
def jars = ['app-5.0.0.jar', 'app-5.1.1.jar', 'app-5.2.0-9.jar', 'app-5.2.0-10.jar', 'app-5.2.0.jar', 'app-5.1.0.jar', 'app-5.1.1-172.jar']
jars.sort{ a, b ->
def aList = a.findAll(/\d+/)
def bList = b.findAll(/\d+/)
for ( int i = 0 ; i < aList.size() ; i++ ) {
def aVal = aList[i] ? aList[i].toInteger() : 0
def bVal = bList[i] ? bList[i].toInteger() : 0
if ( aVal <=> bVal ) { // only return if non-zero i.e. not equal
return aVal <=> bVal
}
}
bList.size() > aList.size() ? -1 : 0 // all facets match up to now, if b has additional parts it must be later version
}
println jars.reverse()
获取:
[app-5.2.0-10.jar, app-5.2.0-9.jar, app-5.2.0.jar, app-5.1.1-172.jar, app-5.1.1.jar, app-5.1.0.jar, app-5.0.0.jar]
答案 1 :(得分:1)
这样的事情怎么样:
for(int i = 0; i<no; i++){
printf("What is student %d name?\n", i+1);
scanf(" %[^\n]", &p[i].name); // mutate the ith student in p
// ...
}
输出:
def jars = ['app-5.0.0.jar', 'app-5.1.1.jar', 'app-5.2.0-9.jar', 'app-5.2.0-10.jar', 'app-5.2.0.jar', 'app-5.1.0.jar', 'app-5.1.1-172.jar']
// it is probably sufficient to just choose a "high enough" number
// (e.g. 10) instead of resolving max digits.
def maxDigits = jars*.findAll(/\d+/).flatten()*.size().max()
// sort the strings consisting of left-padded version numbers
// e.g. sorting string for 'app-5.1.1-172.jar' is ' 5 1 1172'
jars.sort{ it.findAll(/\d+/)*.padLeft(maxDigits).join() }
println 'max digits: ' + maxDigits
println jars.reverse()
