Re: How do I use Regex substitution?It can't learn these advanced techniques in a script guide.
Re: How do I use Regex substitution?Thanks!
It is hard to make good examples for some features in regex. This is a good example for lookaround. I think I could do it without lookaround, but it would be more complicated. @shannon_conners for the doc team: using positive and negative, ahead and behind, together, is what makes this compact and expressive (with a comment). It is an unusual situation, not mainstream usage.
Re: How do I use Regex substitution?Thank Craige!
I'd like to ask you a question about the underlying application:
I want to use JSL to solve more usage, can not use python and other tools.
Of course, I learned all of the JSL code from the many experts in this community.
My request is specifically:
how to restore protobuf(Google Protocol Buffe)-formatted binary text to JMP text ues JSL.
Re: How do I use Regex substitution?
Thanks!
h = [=> ];
u = "http://ds.m.emoney.cn/pick";
h["X-Protocol-Id"] = "8900";
h["X-Request-Id"] = "null";
b = Char To Blob( "~0A~0D~E5~BD~93~E6~97~A5~42~E7~82~B9~E8~82~A1~10~F2~DF~D2~09", "ascii~hex" );
rs = New HTTP Request( URL( u ), Method( "POST" ), JSON( b ), Headers( h ) );
rr = rs << Send;
Re: How do I use Regex substitution?Re: How do I use Regex substitution?Interesting https://developers.google.com/protocol-buffers/docs/overview
It looks like you have two choices: write your own https://github.com/protocolbuffers/protobuf/blob/master/docs/third_party.md which would then work for many protocols,
or, easier and harder,
pick an existing one and translate. I have not looked at it, but I might try starting with a JAVA version and translate that to JSL. But then you get to repeat the translation for the next protocol.
It would be a pretty cool project to make a translator. I do not plan to do that.
Re: How do I use Regex substitution?Thank you so much Craige!
I know it's a very difficult job.Thank you for writing a general framework, I will try to learn more knowledge to modify.Thank you for your efforts.
Re: How do I use Regex substitution?use two statements. I added some extra problem characters to your example...
txt = "d试1(-是2^3([a]文/字789(+内\c容4$3";
step1 = Regex( txt, "\(", "\!n", globalreplace );
step2 = Regex( step1, "[-+/\\^$[\]a-zA-Z]", "", globalreplace );
</CODE>The ( needs to be regex-escaped for step1. The newline is JSL-escaped.</P>
<P><CODE class=" language-jsl">For step2, the syntax of the [...] is complicated:
- start with the - because without a leading character it can't be a range like a-z. (Otherwise it needs a regex-escape, \- )
- the \ needs to be regex-escaped
- the ] needs to be regex-escaped
Be careful not to accidentally write the JSL-escape \[ which changes the way JSL interprets strings. This is likely to happen when working with character sets in [...] if you don't know it will be a problem.
Notice the sequence [\]. It is not a character set. It is 2 characters that are in a character set.
How do I use Regex substitution?Replaces the specified "(" with a newline character and removes all non-Chinese and non-numeric characters.
d试1(-是23(a文字789(+内c容4$3
txt="d试1(-是23(a文字789(+内c容4$3";
na=Regex(txt, ？？ );
Thanks!
Advanced Statistical ModelingRe: How do I use Regex substitution?Thank Craige!
I'll just use EmEditor to re replace
Re: How do I use Regex substitution?
Thank Craige!
If I want to take this re substitution one step further: insert tabs between the Chinese characters and the data (set the Chinese characters in the original text to the left and the numbers to the right), to achieve a table that can input the result of the substitution directly into the JMP:
How do you need to change the code?
txt = "d试1(-是2^3([a]文/字789(+内\c容4$3";
step1 = Regex( txt, "\(", "\!n", globalreplace );//？？
step2 = Regex( step1, "[-+/\\^$[\]a-zA-Z]", "", globalreplace );//？？
s = N Items( step2 );
dt = New Table( "A", Add Rows( s ), New Column( "txt", Character, "Nominal" ), New Column( "num" ) );
dt[0, 0] = step2;
Re: How do I use Regex substitution?This is an example for negative look behind and positive look ahead, lookaround. Step 3 is using both.

Look at the code you write, a real enjoyment!
