When it comes to VCS, well, the current situation is quite poor, so I’d welcome better tools there.

Existing VCS could work reasonably well if the serialisation/“text projection” was deterministic and ‘stable’, i.e. minimising the amount of spurious changes like re-ordering of definitions, etc. As a first approximation I can imagine an s-expression language arranging the top-level expressions into lexicographic order, spreading them out so each sub-expression gets its own line, normalising all unquoted whitespace, etc. This would be like a very opinionated gofmt.

If users wan’t to preserve some layout/etc. then the editor can store that as metadata in the file. I agree that semantics-aware diffing would be great though ;)

The way I see it is that there are tools for turning text into an AST and you can use them to build the fancy things you want. My point wasn’t ‘you can write that sort as a one-off’. You can edit code written in a text-based programming language with a really fancy editor that immediately parses it to an AST and works with it as an AST, and only turns it into text when written to disk. I have no problem with that. But really you’re still editing text when using something like paredit.

Something like vim but where the text objects are ‘identifier’, ‘ast node’, ‘expression’, ‘statement’, ‘logical line of code’, ‘block’, etc. rather than ‘text between word separators’, ‘text between spaces’, ‘line’, etc. would be a useful thing. In fact, you could probably do this in vim. I have an extension I use that lets you modify quotes around things taking into account escaped quotes within, etc. That’d probably work way better if it had that default structure for normal text and then could be customised to actually take into account the proper grammar of particular programming languages for which that is supported.

What I’m concerned about is the idea that it’s a good idea to store code in a proprietary binary file format that’s different for every language, where you can’t use the same tools with multiple languages. And then having to reimplement the same basic functionality for every single language in separate IDEs for each, where everything works slightly differently.

I do find it useful that I can do ci( and vim will delete everything inside the nearest set of parentheses, properly taking into account nesting. So if I have (foo (hello 1 2 3) bar) and my cursor is on the a, it’ll delete everything, even though the nearest ( and ) are beside hello and not foo. That kind of thing, more structured editing? I’m all for that.

Consequently, for pastebin or StackOverflow, you could just paste some text projection of the code, no problem. When it comes to VCS, well, the current situation is quite poor, so I’d welcome better tools there. For example, if there was a VCS that showed me diffs that take into account the semantics of the language (eg like this: https://www.semanticmerge.com), that would be pretty cool.

Ultimately I think if you have a recognised standardised text projection of your code, you might as well just make that the standardised format for it, then your fancy editor or editor plugin can parse it into the structures it needs. This helps ensure you can edit code over SSH, and have a variety of editors compatible with it, rather than just the single language-designer-provided IDE.

One of the nice things about git is that it stores snapshots internally rather than diffs. So if you have a language-specific tool that can produce diffs that are better due to being informed by the grammar of the language (avoiding the problem of adding a function and the diff being ‘added a new closing brace to the previous function then writing a new function except for a closing brace’, for example), then you can do that! Change the diff algorithm.

For the rest of your objections, I offer this analogy: imagine that we only had ASCII pictures, and none of this incompatible JPG/PSD/PNG nonsense with few complicated tools. Then we could use generic tools for working with text to manipulate these files, and we wouldn’t be constrained in any way whether we wanted to create beautiful paintings or complex diagrams. That’s the thing about text!

Well I mean I do much prefer creating a graph by writing some code to emit DOT than by writing code to emit PNG. I did so just the other day in fact. http://rout.nz/nfa.svg. Thank god for graphviz, eh?

Note that there’s also for example farbfeld, and svg, for that matter: text-based formats for images. Just because it’s text underneath doesn’t mean it has to be rendered as ASCII art.

I think it’s wrong to say that the text storage is incidental. Line-oriented text files are about the lowest common denominator way we have to store data like this.

For starters, it’s effectively human-readable – you can lift the hood up and look at what’s underneath, understanding the effect that each individual character has on the result. Any more complicated structure, as would be generally required to have a more machine-first structured approach to program storage, is not going to have that property; at least not to the same extent.

If this thread demonstrates anything, it’s that we all have (at times, starkly!) different preferences for software engineering tools. Falling back on a textual representation allows us to avoid the need to seek consensus on a standard set of tools – I can use the editor and code manipulation tools that make sense to me, and you can stick to what makes sense to you. I think a lot of the UNIX philosophy posturing ends up being revisionist bunk, but the idea that text is a pretty universal interface for data interchange isn’t completely without merit.

Many things can be “queried” with grep and regular expressions. Which is also great to find “similar occurrences” that need to be checked but are only related by some operators and function calls following another. But on the other hand I’d definitely argue that IDEs at least have a tiny representation of the current source file for navigation or something and that you can click some token and find its uses, definitions, implementations … But it only works if I disable the low power mode. And with my 8Gb RAM MacBook I sometimes have to kill the IDE before running the program to make sure I can still use it at the same time.

Exactly. And it could extend beyond search; code could be manipulated and organised in more powerful ways. We still have rudimentary support for refactoring in most IDEs, and so we keep going through files and manually making structurally similar changes one by one, for no reason other than the inadequate underlying representation used for code.

I could be wrong and maybe this is impossible to implement in any kind of general way beyond the few specific examples I’ve thought of, but I find it strange that most people dismiss the very possibility of anything better despite the fact that it’s obviously difficult and inconvenient to work with textual source code.

The version of cscope that I use does things of that nature. The list of queries it supports:

Find this C symbol:
Find this global definition:
Find functions called by this function:
Find functions calling this function:
Find this text string:
Change this text string:
Find this egrep pattern:
Find this file:
Find files #including this file:
Find assignments to this symbol:

I use Find functions calling this function a lot, as well as Find assignments to this symbol. You could conceivably add more query types, and I’m certain there are other tools that are less to my admittedly terminal-heavy aesthetic preference that offer more flexible code search and analysis.

The base structure of the software being textual doesn’t get in the way of this at all.

I bring it up as a good example because I use it all the time to great effect while working on large scale software projects. It is relatively simple to understand what it does, it’s been relatively reliable in my experience, and it helps a lot in understanding the code I work on. I’ve also tried exuberant ctags on occasion, and it’s been pretty neat as well.

I don’t feel stuck at all. In fact, I feel wary of people attempting to invalidate positive real world experiences with assertions that merely because something has been around for a long time that it’s not still a useful way to work.

Most people don’t bother to learn vimscript properly, treating it much like people treated Javascript for years: a bunch of disparate bits they’ve picked up over time, with no unifying core. But once you actually learn it, it becomes much easier to use and more consistent. The difference between expressions and commands becomes sensible instead of seeming like an inconsistency.

I never get fed up with the limitations of text-only programming, because I don’t think they exist. Could you elaborate on what you are saying those limitations are?

And I totally, 100% disagree with any claim that vim’s UI is bad or inconsistent. On the contrary, it’s extremely consistent. It’s not a bunch of little individual inconsistent commands, it’s motions and text objects and such. It has extensive and well-written help. Compared to any other IDE I’ve used (a lot), it’s way more consistent. Every time I use a Mac program I’m surprised at how ad-hoc the random combinations of letters for shortcuts are. And everything requires modifier keys, which are written with ridiculous indecipherable symbols instead of ‘Ctrl’ ‘Shift’ ‘Alt’ etc. Given that Mac is generally considered to be very easy to use, I don’t think typical general consensus on ease of use is very instructive.

I should have worded that differently… I don’t timestamp messages all that often. What I meant to convey is that $1000/mo is definitely overkill for anyone with intermittent needs.

Pastebin and forum posts are fine, but centralized. If Pastebin ever goes down, or starts manipulating old posts, then the integrity of your verification is compromised. Embedding the message in Ethereum’s blockchain is a much stronger guarantee of permanence and immutability.

What sorts of blog posts need such tamper-proofing? Anything dealing with warrant canaries, reverse engineering, or low-level firmware might deserve it.

Yeah, you’d really need to know the use case to try to use it as justification for the Bitcoin blockchain and all its baggage. As the full quote from the linked article says:

Truly immutable timestamps could be useful — assuming anyone finds a timestamp use case so important that it warrants a country-sized percentage of the world’s electricity consumption.

There’s probably a post I need to write on this topic: basically, we’re going to see a resurgence in the popularity of linked lists with hashes, and they’re going to be branded “blockchain(tm)”. There are a few non-bogus projects along these lines, but it’s not so great actually and in all cases they should have just used a frickin database.

Likely case, we get mostly-working systems that have an eternally painful “blockchain(tm)” implementation at the core that can’t easily be replaced by something sane.

Yes, that would be nice maybe we can get the owner of minus.app to add them too.
