I predict this will never happen under the principle of "good enough to use, bad enough to complain on HN." My point is that people keep suggesting ASCII delimiters as if it's some obvious solution that solves the entire problem, but it doesn't. People should instead be suggesting that text editors better support ASCII delimiters so that we can use them roughly as easily as we use commas today.
No, but I do it for formats like HTML, CSS, JSON. My editor can assist me, but I don't need it. To a lesser degree, the same is true of Java, though I do admit to leaning much more heavily on my IDE for that.
> What is this obsession with hand-coding complicated formats :)
Well, part of it is that they're not all that complicated unless you're doing something fancy. Another part is almost certainly our (we as in developers) pride in being able to use nothing but vi installed on a decade-old operating system to get things done.
Downsides include:
XSS and malicious injection - users should be using markdown or provided an actual contentEditable HTML editor instead of a textarea. Like in GMail.
Syntax errors. How many times have you typed some JSON by hand and realized you forgot to balance some braces or add a comma, or remove a comma at the end of an object?
Complexity not that complicated, really? Basic C, HTML, CSS is not complicated. Advanced stuff is complicated. Forgetting a brace or a semicolon torpedoes the whole document. SQL is not complicated. Does that mean you want to write SQL by hand for production code?
Why don't you install a simple extension to vi like an html format adapter? I'm a developer too. But let me tell you what it sounds like when you say you want to use nothing but vi: that's like saying you want to be able to build robots using nothing but a hammer and some nails, and nothing else can be built that requires further abstraction or advancement where you can't do the same with a hammer.
And also keep in mind that not everyone is a developer. The fact that you like to keep esoteric syntax rules in your head for HTML, XML, CSS, Javascript, C++ and so on doesn't mean EVERYONE should have to. When it comes to CSV, it's not even a real standard. You have to keep in your head all the cross platform quirks, like \r\n garbage similar to how web developers need to keep in their head all te Browser quirks and workarounds.
All this... for some pride thing of being able to write text based stuff by hand.
I brought up RTF for a reason. No sane person should want to type .rtf or .docx by hand. So why HTML?
1) there are so many differences between browsers that you have to keep them all in mind when asking people to send you csv files, or generating them, etc. Such as for example \n vs \r vs \r\n and escaping them.
2) You have to keep in your head escape rules and exceptions, and balancing quotes and other delimiters.
3) The whole thing doesn't look human readable or easily navigable for a document of any serious complexity.
And what's the upside? If more people just used Excel or another spreadsheet program to edit these files, you won't face ANY of these issues. They would eventually converge on a standard format, like they did with HTML.
Disclaimer: I wrote a CSV parser
Compatibility horrors from people violating the standard will appear no matter what format you use. That's not fair to blame on the format.
> You have to keep in your head escape rules and exceptions, and balancing quotes and other delimiters.
CSV itself has newlines, commas, and quotations marks for special characters. That's extremely minimal. The only extra thing to keep in your head is "is this field quoted or not".
What set of escapes and delimiters could be simpler? Would you rather reserve certain characters, and abandon the idea of holding "just text" values?

This sounds like you're arguing for a more complex format! I'm confused.
So again, what is a format that you call simple?
There's a lot of design room here.
https://www.lua.org/pil/2.4.html http://prog21.dadgum.com/172.html
I can no longer remember where I saw it (thought it was lua), but I heard the idea to use =[[ ... ]]= and =[[[ ... ]]]= as wrappers (a bit like the qq operator from perl). They can be nested and don't interfere, so =[[[ abc =[[ ]]= ]]]= is a legitimate string.
Ascii text format is simple.
Anything where you have arbitrarily complex structure, why not use a program to edit it? What is the downside of using the right tool for the job? Your text editor is a program. Why tunnel through text and manually edit stuff?
* shouldn't ≠ doesn't
The only consistent thing about CSV is its ubiquity; other than that, it's a hairy, inconsistent mess that appears simple. (Source: having parsed millions of blobs that all identified themselves as CSV, despite being almost completely different in structure.)
CSV is comma separated. [1]
Valid YAML
foo: bar baz
Invalid YAML foo: "bar" baz
Valid YAML foo: "bar baz"
Invalid YAML foo: "bar baz
Valid YAML foo: bar baz"
[1] https://tools.ietf.org/html/rfc4180From your link, it's quite clear that you should not assume any particular CSV file to follow any particular rules.
> Interoperability considerations: > Due to lack of a single specification, there are considerable differences among implementations. Implementors should "be conservative in what you do, be liberal in what you accept from others" (RFC 793 [8]) when processing CSV files. An attempt at a common definition can be found in Section 2....
> Published specification: > While numerous private specifications exist for various programs and systems, there is no single "master" specification for this format. An attempt at a common definition can be found in Section 2.
Section 2 states:
> This section documents the format that seems to be followed by most implementations:
If CSV were indeed always comma-separated, my hair would be at least 5% less gray. Alas, most programs emit semicolon-separated "CSV" in some locales (MS Office, LibreOffice, you-name-it-they-got-it).
Of course, I understand that your academic position "if it chokes the RFC-compliant parser, it's not a True CSV and should be sent to /dev/null" tautologically exists - but for some reason, users tend to object to such treatment (especially when they have no useful tools that would emit your One True Format for them).
TL;DR: there is no single standard fitting all the things that call themselves "CSV".
In other words, as soon as you start exchanging data, you'll get something that is complex, broken, or (most common case) both. Existence of a simple, consistent general format has not been conclusively proven impossible, but I have yet to see one in practice.
(Of course, everybody and their dog have cooked up simple data schemes, yes, but those are a) domain-specific, and b) not in widespread use.)
Sure, if you're building some kind of system where you need to ingest data from one application from another application you control, then using a different interchange format like ASV is an option. But then people tend to use more powerful formats like JSON or XML.
That, and data in CSV format is human readable in any old text editor or even work processor which many use as a quick sanity check to make sure their data looks sane. A lot of editors will not display the ASCII control characters at all so the fields on the line get mashed together, or may even reject the file as containing what it considers to be unexpected characters.
While it's great to hope to use a well defined transport for machine-to-machine communication, it's exhausting to explain anything beyond CSV to Bob from sales.
Worse; most 'non computer people' cannot get them imported into a spreadsheet properly (for whatever reason; usually it just puts everything in one field or column, people curse and give up), so they have to edit them in Notepad or worse, in MS Word and then send them back.
Not really seeing the beauty I guess.

ASCII Name - Vim Insert - Visual Repr
--------------------------------------------------
Start of Heading - Ctrl-v Ctrl-a - ^A
Start of Text - Ctrl-v Ctrl-b - ^B
End of Text - Ctrl-v Ctrl-c - ^C
End of Transmission - Ctrl-v Ctrl-d - ^D
File Separator - Ctrl-v Ctrl-\ - ^\
Group Separator - Ctrl-v Ctrl-] - ^]
For insertion you can also always just Ctrl-v DDD or Ctrl-v xHH where DDD is the three digit decimal value or HH is two hex values of the ascii code.Accordingly, the reference to "54 year old" appears to be to the first standard as well as first commercial use of ASCII, in 1963.
That first ASCII standard from 1963 specified eight "separators" simply named S0 through S7 at codes 0x18--0x1F. The 1965 update reused the first four for other purposes (eg cancel and escape) and labeled 0x1C--0x1F with the more descriptive names we now know.
I know the response will be "they'll just open it in Excel anyway" which is true in most cases, but I frequently have clients that want to download an export, modify it real quick with a text editor (many use Notepad++ for this), and then reupload it. They're usually doing massive find/replaces on the data and then reuploading into the system and a simple text editor is a lot better for this than Excel.
Emacs defaults to a menu + toolbar and the arrow/pageup/pagedown/home/end keys are functional. There are buttons with icons and labels for new document, open document, find in document, and copy/cut/paste. It's friendlier to use than something like Notepad++, gedit, or kate out of the box for simple editing. For more complicated stuff, there are menus and extensive documentation. The narrative that emacs is impossible to use for any but the programming elite doesn't fit the default experience.
If you define competently use as can extensively configure beyond the default state, then I'd argue that very few recent developers outside of those who use vim/emacs users have ever done so. How many people have you met who have written C# to extend Visual Studio or some Java to extend Eclipse/IntelliJ. Even with things like Atom, how many of those Atom users are writing Javascript packages versus using the packages someone else wrote?
If you define competently use as "be able to edit and debug in $x language", I'd argue the menu-driven approach in emacs is just as valid as the menu-driven in approach in any other random gui editor. The difference is that emacs can be customized and has decades of documentation and examples to pull from for any conceivable scenario. Want to interact with your editing environment with foot pedals, talk on that fancy new chat interface, interface with a serial port to pull sensor data or control a personal massager? You can find someone who has done it and documented it on emacs.
Someone who cannot competently use either vim or emacs is not a developer.
> The number of non-devs that can do it is far lower.
The emacs paper talked about departmental secretaries using — and extending — emacs. Human beings are far cleverer than we like to think.
Some people never learned either of the editors. So what? The physical act of writing text was never the hard part of software engineering.
If Excel decides that text between Start of Text and End of Text that begins with a "=" is a formula, then you're in the same spot.
I use CSV all the time when I am working with R. My data can come in the form of CSV, XLS, or PDF. Which would you want to work with?
I can easily look at the data. I never touch my incoming data and my output is in reports, but CSV can be the easiest way to get data into a computer.
"ASV" is only a viable option if you then also use your time machine to go back 40 years and make everyone start using it then.
ASCII had addressed the problem of separating entries ever since its creation: Separator control codes. There are:
x01 SOH "Start of Heading"
x02 STX "Start of Text"
x03 ETX "End of Text"
x04 EOT "End of Transmission"
x1C FS "File Separator"
x1D GS "Group Separator"
x1E RS "Record Separator"
x1F US "Unit Separator"
You can use those just fine for exchanging data as you would using CSV, but without the ambiguities of separation characters and the need to quote strings. Heck if payload data is limited to the subset ASCII/UTF-8 without control codes you can just dump anything without the need for escaping or quoting.
So my suggestion is simple. Don't use CSV or "P"SV (printable separated values). Use ASV (ASCII separated values).
