# Features
|
||||
|
||||
`dtl` provides the functions for comparing two sequences have arbitrary type. But sequences must support random access\_iterator.
|
||||
|
||||
# Getting started
|
||||
|
||||
To start using this library, all you need to do is include `dtl.hpp`.
|
||||
|
||||
```c++
|
||||
#include "dtl/dtl.hpp"
|
||||
```
|
||||
|
||||
## Compare two strings
|
||||
|
||||
First of all, calculate the difference between two strings.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::string sequence;
|
||||
sequence A("abc");
|
||||
sequence B("abd");
|
||||
dtl::Diff< elem, sequence > d(A, B);
|
||||
d.compose();
|
||||
```
|
||||
|
||||
When the above code is run, `dtl` calculates the difference between A and B as Edit Distance and LCS and SES.
|
||||
|
||||
The meaning of these three terms is below.
|
||||
|
||||
| Edit Distance | Edit Distance is numerical value for declaring a difference between two sequences. |
|
||||
|:--------------|:-----------------------------------------------------------------------------------|
|
||||
| LCS | LCS stands for Longest Common Subsequence. |
|
||||
| SES | SES stands for Shortest Edit Script. I mean SES is the shortest course of action for tranlating one sequence into another sequence.|
|
||||
|
||||
If one sequence is "abc" and another sequence is "abd", Edit Distance and LCS and SES is below.
|
||||
|
||||
| Edit Distance | 2 |
|
||||
|:--------------|:----------------|
|
||||
| LCS | ab |
|
||||
| SES | C a C b D c A d |
|
||||
|
||||
* 「C」：Common
|
||||
* 「D」：Delete
|
||||
* 「A」：ADD
|
||||
|
||||
If you want to know in more detail, please see [examples/strdiff.cpp](https://github.com/cubicdaiya/dtl/blob/master/examples/strdiff.cpp).
|
||||
|
||||
This calculates Edit Distance and LCS and SES of two strings received as command line arguments and prints each.
|
||||
|
||||
When one string is "abc" and another string "abd", the output of `strdiff` is below.
|
||||
|
||||
```bash
|
||||
$ ./strdiff abc abd
|
||||
editDistance:2
|
||||
LCS:ab
|
||||
SES
|
||||
a
|
||||
b
|
||||
-c
|
||||
+d
|
||||
$
|
||||
```
|
||||
|
||||
## Compare two data has arbitrary type
|
||||
|
||||
`dtl` can compare data has aribtrary type because of the C++'s template.
|
||||
|
||||
But the compared data type must support the random access\_iterator.
|
||||
|
||||
In the previous example, the string data compared,
|
||||
|
||||
`dtl` can also compare two int vectors like the example below.
|
||||
|
||||
```c++
|
||||
int a[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
|
||||
int b[10] = {3, 5, 1, 4, 5, 1, 7, 9, 6, 10};
|
||||
std::vector<int> A(&a[0], &a[10]);
|
||||
std::vector<int> B(&b[0], &b[10]);
|
||||
dtl::Diff< int > d(A, B);
|
||||
d.compose();
|
||||
```
|
||||
|
||||
If you want to know in more detail, please see [examples/intdiff.cpp](https://github.com/cubicdaiya/dtl/blob/master/examples/intdiff.cpp).
|
||||
|
||||
## Merge three sequences
|
||||
|
||||
`dtl` has the diff3 function.
|
||||
|
||||
This function is that `dtl` merges three sequences.
|
||||
|
||||
Additionally `dtl` detects the confliction.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::string sequence;
|
||||
sequence A("qqqabc");
|
||||
sequence B("abc");
|
||||
sequence C("abcdef");
|
||||
dtl::Diff3<elem, sequence> diff3(A, B, C);
|
||||
diff3.compose();
|
||||
if (!diff3.merge()) {
|
||||
std::cerr << "conflict." << std::endl;
|
||||
return -1;
|
||||
}
|
||||
std::cout << "result:" << diff3.getMergedSequence() << std::endl;
|
||||
```
|
||||
|
||||
When the above code is run, the output is below.
|
||||
|
||||
```console
|
||||
result:qqqabcdef
|
||||
```
|
||||
|
||||
If you want to know in more detail, please see [examples/strdiff3.cpp](https://github.com/cubicdaiya/dtl/blob/master/examples/strdiff3.cpp).
|
||||
|
||||
## Patch function
|
||||
|
||||
`dtl` can also translates one sequence to another sequence with SES.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::string sequence;
|
||||
sequence A("abc");
|
||||
sequence B("abd");
|
||||
dtl::Diff<elem, sequence> d(A, B);
|
||||
d.compose();
|
||||
string s1(A);
|
||||
string s2 = d.patch(s1);
|
||||
```
|
||||
|
||||
When the above code is run, s2 becomes "abd".
|
||||
The SES of A("abc") and B("abd") is below.
|
||||
|
||||
```console
|
||||
Common a
|
||||
Common b
|
||||
Delete c
|
||||
Add d
|
||||
```
|
||||
|
||||
The patch function translates a sequence as argument with SES.
|
||||
For this example, "abc" is translated to "abd" with above SES.
|
||||
|
||||
Please see dtl's header files about the data structure of SES.
|
||||
|
||||
## Difference as Unified Format
|
||||
|
||||
`dtl` can also treat difference as Unified Format. See the example below.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|

In addtion, `dtl` has the function translates one sequence to another sequence with Unified Format.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::string sequence;
|
||||
sequence A("abc");
|
||||
sequence B("abd");
|
||||
dtl::Diff<elem, sequence> d(A, B);

|
||||
string s2 = d.UniPatch(s1);
|
||||
```
|
||||
|
||||
When the above code is run, s2 becomes "abd".
|
||||
The uniPatch function translates a sequence as argument with Unified Format blocks.
|
||||
|
||||
For this example, "abc" is translated to "abd" with the Unified Format block below.

## Compare large sequences
|
||||
|
||||
When compare two large sequences, `dtl` can optimizes the calculation of difference with the onHuge function.
|
||||
|
||||
But this function is could use when the compared data type is std::vector.
|
||||
|
||||
When you use this function, you may call this function before calling compose function.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::vector<elem> sequence;
|
||||
sequence A;
|
||||
sequence B;
|
||||
/* ・・・ */
|
||||
dtl::Diff< elem, sequence > d(A, B);
|
||||
d.onHuge();
|
||||
d.compose();
|
||||
```
|
||||
|
||||
## Unserious difference
|
||||
|
||||
The calculation of difference is very heavy.
|
||||
`dtl` uses An O(NP) Sequence Comparison Algorithm.
|
||||
|
||||
Though this Algorithm is sufficiently fast,
|
||||
when difference between two sequences is very large,
|
||||
|
||||
the calculation of LCS and SES needs massive amounts of memory.
|
||||
|
||||
`dtl` avoids above-described problem by dividing each sequence into plural subsequences
|
||||
and joining the difference of each subsequence finally.
|
||||
|
||||
As this way repeats allocating massive amounts of memory,
|
||||
`dtl` provides other way. It is the way of calculating unserious difference.
|
||||
|
||||
For example, The normal SES of "abc" and "abd" is below.
|
||||
|
||||
```console
|
||||
Common a
|
||||
Common b
|
||||
Delete c
|
||||
Add d
|
||||
```
|
||||
|
||||
The unserious SES of "abc" and "abd" is below.
|
||||
|
||||
```console
|
||||
Delete a
|
||||
Delete b
|
||||
Delete c
|
||||
Add a
|
||||
Add b
|
||||
Add d
|
||||
```
|
||||
|
||||
Of course, when "abc" and "abd" are compared with `dtl`, above difference is not derived.
|
||||
|
||||
`dtl` calculates the unserious difference when `dtl` judges the calculation of LCS and SES
|
||||
needs massive amounts of memory and unserious difference function is ON.
|
||||
|
||||
`dtl` joins the calculated difference before `dtl` judges it and unserious difference finally.
|
||||
|
||||
As a result, all difference is not unserious difference when unserious difference function is ON.
|
||||
|
||||
When you use this function, you may call this function before calling compose function.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::string sequence;
|
||||
sequence A("abc");
|
||||
sequence B("abd");
|
||||
dtl::Diff< elem, sequence > d(A, B);
|
||||
d.onUnserious();
|
||||
d.compose();
|
||||
```
|
||||
|
||||
## Calculate only Edit Distance
|
||||
|
||||
As using onOnlyEditDistance, `dtl` calculates the only edit distance.
|
||||
|
||||
If you need only edit distance, you may use this function,
|
||||
because the calculation of edit distance is lighter than the calculation of LCS and SES.
|
||||
|
||||
When you use this function, you may call this function before calling compose function.
|
||||
|
||||
```c++
|
||||
typedef char elem;
|
||||
typedef std::string sequence;
|
||||
sequence A("abc");
|
||||
sequence B("abd");
|
||||
dtl::Diff< elem, sequence > d(A, B);
|
||||
d.onOnlyEditDistance();
|
||||
d.compose();
|
||||
```
|
||||
|
||||
# Algorithm
|
||||
|
||||
The algorithm `dtl` uses is based on "An O(NP) Sequence Comparison Algorithm" by described by Sun Wu, Udi Manber and Gene Myers.
|
||||
|
||||
An O(NP) Sequence Comparison Algorithm(following, Wu's O(NP) Algorithm) is the efficient algorithm for comparing two sequences.
|
||||
|
||||
## Computational complexity
|
||||
|
||||
The computational complexity of Wu's O(NP) Algorithm is averagely O(N+PD), in the worst case, is O(NP).
|
||||
|
||||
## Comparison when difference between two sequences is very large
|
||||
|
||||
Calculating LCS and SES efficiently at any time is a little difficult.
|
||||
|
||||
Because that the calculation of LCS and SES needs massive amounts of memory when a difference between two sequences is very large.
|
||||
|
||||
The program uses that algorithm don't consider that will burst in the worst case.
|
||||
|
||||
`dtl` avoids above-described problem by dividing each sequence into plural subsequences and joining the difference of each subsequence finally.(This feature is supported after version 0.04)
|
||||
|
||||
## Implementations with various programming languages
|
||||
|
||||
There are the Wu's O(NP) Algorithm implementations with various programming languages below.
|
||||

# Running tests
|
||||
|
||||
`dtl` uses [googletest](http://code.google.com/p/googletest/) and [SCons](http://www.scons.org/) with testing dtl-self.
|
||||
|
||||
# Building test programs
|
||||
|
||||
If you build test programs for `dtl`, run `scons` in test direcotry.
|
||||
|
||||
```bash
|
||||
$ GTEST_ROOT=${gtest_root_dir} scons
|
||||
```
|
||||
|
||||
# Running test programs
|
||||
|
||||
If you run all tests for `dtl`, run 'scons check' in test direcotry. (it is necessary that gtest is compiled)
|
||||
|
||||
```bash
|
||||
$ GTEST_ROOT=${gtest_root_dir} scons check
|
||||
```
|
||||
|
||||
If you run sectional tests, you may exeucte `dtl_test` directly after you run `scons`.
|
||||
Following command is the example for testing only Strdifftest.
|
||||
|
||||
```bash
|
||||
$ ./dtl_test --gtest_filter='Strdifftest.*'
|
||||
```
|
||||
|
||||
`--gtest-filters` is the function of googletest. googletest has many useful functions for testing software flexibly.
|
||||
If you want to know other functions of googletest, run `./dtl_test --help`.
