In Rebol you could parse a line with
parse line ",.#;"
In Red, is there an equivalent ?
The next to that is split, although just a mezzanine wrapper for parse with a special rule. You can use it with multiple delimiters like that
split line charset ",.#;"
Red moved this functionality to split, but I see that it doesn’t work with multiple delimiters as in your case. I will report it as bug.
UPDATE: See https://github.com/red/red/issues/3095

In vue, is there a way to have a value span multiple lines in an .env file. Ex:
Instead of:
someValue=[{"someValue":"Here is a really really long piece which should be split into multiple lines"}]
I want to do something like:
someValue=`[{"someValue":"Here is a really
really long piece which
should be split into multiple lines"}]`
Doing the latter gives me a JSON parsing error if I try to do JSON.parse(someValue) in my code
I don't know if this will work, but I can't format a comment appropriately enough to get the point across so see if this will work:
someValue=[{"someValue":"Here is a really\
really long piece which\
should be split into multiple lines"}]
Where "\" should escape the newline similar to how you can write long bash commands while escaping the newline. I'm not certain the .env interpreter will support it though.
EDIT
Looks like this won't work. This syntax was actually proposed, but I don't think it was incorporated. See motdotla/dotenv#333 (which is what Vue uses to parse .env).
Like #zero298 said, this isn't possible. Likely you could delimit the entry with a character that wouldn't show up normally in the text (^ is a good candidate), then parse it within the application using string.replace('^', '\n');
I am using emmet with Coda 2, version 2.6.6. When I use it to create multiple lines, Coda is showing some sort of end of line character.
For instance, if I use section.container>div*4>{$}, I get the following:
At the end of the first three divs is a some sort of EOL character, and I don't know how to get rid of it. I looked through the editor preferences and did not see anything that would allow me to hide that character. I've tried it on two different macs and have the exact same results.
Is there a way to get rid of it.
I've noticed this recently in 2.5.16. it may be related to having mixed line endings.
If you go to Text > Line Endings > Convert to (whatever type of line endings you use), it should clear the symbol.
I have a CSV file which I'm trying to import to a SQL Server table. The file contains lines of 3 columns each, separated by a comma. The only problem is that some of the data in the second column contains an arbitrary number of commas. For example:
1281,I enjoy hunting, fishing, and boating,smith317
I would like to escape all occurrences of commas in each line except the first and the last, such that the result of this line would be:
1281,I enjoy hunting\, fishing\, and boating,smith317
I know I will need some type of regular expression to accomplish this task, but my knowledge of regular expressions is very limited. Currently, I'm trying to use Notepad++ find/replace with regex, but I am open to other ideas.
Any help would be greatly appreciated :-)
Okay, could be a manual stuff. Do this:
Normal find all the , and replace it with \,. Escape everything.
Regex find ^(.*)(\\,) and replace it with $1,.
Regex find (\\,)(.*)$ and replace it with ,$2.
Worked for me in Sublime Text 2.
I have an input file that I want to use the string SPLIT function on for each line, depending on the Type field. However, the description field sometimes has data that has new lines in it so it messes up my file reader since it uses streamreader's readline() function
Handled:
Type|Name|User|Description
Type|Name|User|Description
Unhandled:
Type|Name|User|Description line 1
Description Line 2
Type|Name|User|Description
Besides not being able to validate on 'Type' for each line and keep reading the file for when the next Type field appears, are there any ways folks can come up with to properly read this file?
My solution was to have the file maker replace newline characters in their description field with another unique character that I can later add back in. I'm still interested in solutions from the file reader's perspective though
I know I'm talking to myself a lot here, but I found another solution, which is to remove remove line feeds, since the output file creator wrote out carriage returns for each line.
You could easily set a conditional statement to see if the Split array contains more than one element, which would indicate that it's a line you want to parse.
I've made some good progress with my first attempt at a program, but have hit another road block. I'm taking standard output (as a string) froma console CMD window (results of dsquery piped to dsget) and have found small rectangles in the output. I tried using Regex to clean the little bastards but it seems they are related to the _ (underscore), which I need to keep (to return 2000/NT logins). Odd thing is - when I copy the caharcter and paste it into VS2K10 Express it acts like a carrige return??
Any ideas on finding out what these little SOB's are -- and how to remove them?
Going to try using /U or /A CMD switch next..
The square is often just used whenever a character is not displayable. The character could very well be a CR. You can use a Regular Expression to just get normal characters or remove the CR LF characters using string.replace.
You mentioned that you are using the string.replace function, and I am wondering if you are replacing the wrong character or something like that. If all your trying to do is remove a carriage return I would skip the regular expressions and stick with the string.replace.
Something like this should work...
strInputString = strInputString.replace(chr(13), "")
If not could you post a line or two of code.
On a side note, this might give some other examples....
