I have an address block like such;
123 Fake St
Suburb, VIC
4512
I want to only remove the last carriage return so it looks like;
123 Fake St
Suburb VIC 4512
Im using the following code which i feel is on the right track but it doesnt change the text at all. Totext is in there because without it i get the message "a string is expected here"
replace({Header.Address},totext(instr(strreverse({Header.Address}),chrw(13))) ,'')
I feel like i only need a small adjustment on this but i just cant quite figure it out. Any help is appreciated.
It looks like the format for the overload of the Replace() function you are using is this.
Replace (inputString, findString, replaceString)
You have defined the value of the findString argument as this.
totext(instr(strreverse({Header.Address}),chrw(13)))
The findString argument has a datatype of String, so you had to add the ToText() function because the InStr() returns an integer value that represents the index of where the carriage return is found in your reversed string. You don't need an index for where the carriage return is located in the string for the overload of the Replace() function you are using, so you can simplify your findString argument to this.
ChrW(13)
This will change your original formula to this.
Replace({Header.Address}, ChrW(13) ,'')
If this still doesn't work, then you may have Line Feed characters in your address data instead of Carriage Return characters. In this case your formula would be this.
Replace({Header.Address}, ChrW(10) ,'')
In some cases you may need to replace both Line Feed and Carriage Return characters. To do this you want this nested version of the formula.
Replace( Replace({Header.Address}, ChrW(10) ,''), ChrW(13) ,'')
Solved elsewhere by;
StrReverse(Replace(Replace(StrReverse({Header.Address}), chr(10), "", 1, 1), chr(13), "", 1, 1))

I'm using AutoHotkey for this as the code is the most understandable to me. So I have a document with numbers and text, for example like this
120344 text text text
234000 text text
and the desired output is
12:03:44 text text text
23:40:00 text text
I'm sure StrReplace can be used to insert the colons in, but I'm not sure how to specify the position of the colons or ask AHK to 'find' specific strings of 6 digit numbers. Before, I would have highlighted the text I want to apply StrReplace to and then press a hotkey, but I was wondering if there is a more efficient way to do this that doesn't need my interaction. Even just pointing to the relevant functions I would need to look into to do this would be helpful! Thanks so much, I'm still very new to programming.
hfontanez's answer was very helpful in figuring out that for this problem, I had to use a loop and substring function. I'm sure there are much less messy ways to write this code, but this is the final version of what worked for my purposes:
Loop, read, C:\[location of input file]
{
{ If A_LoopReadLine = ;
Continue ; this part is to ignore the blank lines in the file
}
{
one := A_LoopReadLine
x := SubStr(one, 1, 2)
y := SubStr(one, 3, 2)
z := SubStr(one, 5)
two := x . ":" . y . ":" . z
FileAppend, %two%`r`n, C:\[location of output file]
}
}
return
Assuming that the "timestamp" component is always 6 characters long and always at the beginning of the string, this solution should work just fine.
String test = "012345 test test test";
test = test.substring(0, 2) + ":" + test.substring(2, 4) + ":" + test.substring(4, test.length());
This outputs 01:23:45 test test test
Why? Because you are temporarily creating a String object that it's two characters long and then you insert the colon before taking the next pair. Lastly, you append the rest of the String and assign it to whichever String variable you want. Remember, the substring method doesn't modify the String object you are calling the method on. This method returns a "new" String object. Therefore, the variable test is unmodified until the assignment operation kicks in at the end.
Alternatively, you can use a StringBuilder and append each component like this:
StringBuilder sbuff = new StringBuilder();
sbuff.append(test.substring(0,2));
sbuff.append(":");
sbuff.append(test.substring(2,4));
sbuff.append(":");
sbuff.append(test.substring(4,test.length()));
test = sbuff.toString();
You could also use a "fancy" loop to do this, but I think for something this simple, looping is just overkill. Oh, I almost forgot, this should work with both of your test strings because after the last colon insert, the code takes the substring from index position 4 all the way to the end of the string indiscriminately.
I have the following string:
{\"Id\":\"135\",\"Type\":0}
The number in the Id field will vary, but will always be an integer with no comma separator. I'm not sure how to get just that value from that string given that it's string data type and not real "XML". I was toying with the replace() function, but the special characters are making it more complex than it seems it needs to be.
is there a way to convert that to XML or something that I can reference the Id value directly?
Maybe use a regular expression, e.g.
import re
txt = "{\"Id\":\"135\",\"Type\":0}"
x = re.search('"Id":"([0-9]+)"', txt)
if x:
print(x.group(1))
gives
135
It is assumed here that the ids are numeric and consist of at least one digit.
Non-regex answer as you asked
\" is an escape sequence in python.
So if {\"Id\":\"135\",\"Type\":0} is a raw string and if you put it into a python variable like
a = '{\"Id\":\"135\",\"Type\":0}'
gives
>>> a
'{"Id":"135","Type":0}'
OR
If the above string is python string which has \" which is already escaped, then do a.replace("\\","") which will give you the string without \.
Now just load this string into a dict and access element Id like below.
import json
d = json.loads(a)
d['Id']
Output :
135
I'm writing a program in Progress, OpenEdge, ABL, and whatever else it's known as.
I have a CSV file that is delimited by commas. However, there is a "gift message" field, and users enter messages with "commas", so now my program will see additional entries because of those bad commas.
The CSV fields are not in double qoutes so I CAN NOT just use my main method with is
/** this next block of code will remove all unwanted commas from the data. **/
if v-line-cnt > 1 then /** we won't run this against the headers. Otherwise thhey will get deleted **/
assign
v-data = replace(v-data,'","',"\t") /** Here is a special technique to replace the comma delim wiht a tab **/
v-data = replace(v-data,','," ") /** now that we removed the comma delim above, we can remove all nuisance commas **/
v-data = replace(v-data,"\t",'","'). /** all nuisance commas are gone, we turn the tabs back to commas. **/
Any advice?
edit:
From Progress, I cal call Linux commands. So I should be able to execute C++/PHP/Shell etc all from my Progress Program. I look forward to advice, until then I shall look into using external scripts.
You are not providing quite enough data for a perfect answer but given what you say I think the IMPORT statement should handle this automatically.
In my example here commaimport.csv is a comma-separated csv-file with quotes around text fields. Integers, logical variables etc have no quotes. The last field contains a comma in one line:
commaimport.csv
=======================
"Id1", 123, NO, "This is a message"
"Id2", 124, YES, "This is a another message, with a comma"
"Id3", 323, NO, "This is a another message without a comma"
To import this file I define a temp-table matching the file layout and use the IMPORT statement with comma as delimiter:
DEFINE TEMP-TABLE ttImport NO-UNDO
FIELD field1 AS CHARACTER FORMAT "xxx"
FIELD field2 AS INTEGER FORMAT "zz9"
FIELD field3 AS LOGICAL
FIELD field4 AS CHARACTER FORMAT "x(50)".
INPUT FROM VALUE("c:\temp\commaimport.csv").
REPEAT :
CREATE ttImport.
IMPORT DELIMITER "," ttImport.
END.
INPUT CLOSE.
FOR EACH ttImport:
DISPLAY ttImport.
END.
You don't have to import into a temp-table. You could import into variables instead.
DEFINE VARIABLE c AS CHARACTER NO-UNDO FORMAT "xxx".
DEFINE VARIABLE i AS INTEGER NO-UNDO FORMAT "zz9".
DEFINE VARIABLE l AS LOGICAL NO-UNDO.
DEFINE VARIABLE d AS CHARACTER NO-UNDO FORMAT "x(50)".
INPUT FROM VALUE("c:\temp\commaimport.csv").
REPEAT :
IMPORT DELIMITER "," c i l d.
DISP c i l d.
END.
INPUT CLOSE.
This will render basically the same output:
You don't show what your data file looks like. But if the problematic field is the last one, and there are no quotes, then your best bet is probably to read it using INPUT UNFORMATTED to get it a line at a time, and then split the line into fields using ENTRY(). That way you can treat everything after the nth comma as a single field no matter how many commas the line has.
For example, say your input file has three columns like this:
boris,14.23,12 the avenue
mark,32.10,flat 1, the grange
percy,1.00,Bleak house, Dartmouth
... so that column three is an address which might contain a comma and is not enclosed in quotes so that IMPORT DELIMITER can't help you.
Something like this would work in that case:
/* ...skipping a lot of definitions here ... */
input from "datafile.csv".
repeat:
import unformatted v-line.
create tt-thing.
assign tt-thing.name = entry(1, v-line, ',')
tt-thing.price = entry(2, v-line, ',')
tt-thing.address = entry(3, v-line, ',').
do v=i = 4 to num-entries(v-line, ','):
tt-thing.address = tt-thing.address
+ ','
+ entry(v-i, v-line, ',').
end.
end.
input close.
I'm creating a plot where I want to combine two strings into a title. I want to color the other part of my string. Here is my code (it will explain itself better):
title([csv_name ', {\color{blue}Bowel AUC: ' num2str(bowelAUC) ' }'])
In the variable csv_name I have a filename containing underscore _ characters and in the variable bowelAUC I have a number. I can color only part of my title string by using the guide in this post, that is using tex, but the problem now is that tex interpreter would also interpret the csv_name variable and I don't want this. Here you can see what I get:
The filename looks like this: ExportedPressure_130A_10-29-2014.csv
So I want title to interpret only the second part of my title, not the first...how to do this?
You need to replace _ by \_ so that TeX interprets them correctly. To do that you can use regexprep (note that within regexprep both characters are escaped again):
csv_name_escaped = regexprep(csv_name, '\_', '\\\_');
title([csv_name_escaped ', {\color{blue}Bowel AUC: ' num2str(bowelAUC) ' }'])
I have a script which does not fully work:
inputfield=input('Which field would you like to see: ','s')
if isfield(package, inputfield)
fprintf('The value of the %s field is: %c\n',inputfield,...
eval(['package.' inputfield]))
else
fprintf('Error: %s is not valid field\n', inputfield)
end
First I define a structure in matlab and then i use the script on the structure:
package=struct('item_no',123,'cost',19.99,'price',39.95,'code','g')
package =
item_no: 123
cost: 19.9900
price: 39.9500
code: 'g'
structurevalue
Which field would you like to see: cost
inputfield =
cost
The value of the cost field is: 1.999000e+001
structurevalue
Which field would you like to see: item_no
inputfield =
item_no
The value of the item_no field is: {
why cant it read value for item_no?
Try:
fprintf('The value of the %s field is: %s\n',inputfield,...
num2str(package.(inputfield)))
There were two issues with your version.
You were passing both numbers and strings into the %c field in your fprintf string. When a decimal goes in, it is interpreted as a number and displayed in full precision, which is why 19.99 got displayed as 1.999000e+001. But when an integer goes in, it gets interpreted as a character, which is why 123 got displayed as '{' (ASCII character 123). Use num2str to convert numbers to strings for display. Also, use %s for a string of any length, rather than %c for a character.
In general, it's not a good idea to use eval unless you have to. In this case, it's more convenient to use inputfield as a dynamic field name of package.
