Which command are you talking about?
@Shamar this isn't really a Plan 9 specific problem, but it's one of those things that mess up an otherwise nice system
To be honest I don't know why one could need spaces in file names.
I should probably forbid them in #Jehanne at kernel level
I can.
Every programmer continuously does that to users: we restrict what you can do with computers so that you can actually do something.
For example you can't put a 0x0 byte in the middle of a file name. Or a "/" in a domain name.
You are so used to our power you can't see it anymore. And actually most programmers are unaware of it.
But the truth is that we CAN tell you what to do and what not. And that's nothing!
Software programmers dictate how people THINK!
And this was true way before Cambridge Analytica: you perceive and act on the world through the software we write.
Through software we shape your synapses.
@Shamar @xj9 You only can't use 0x0 because of C's limitations.
IMHO, type Path = List String (maybe NonEmptyList or something) makes more sense than using char*.
It makes sense in historical context, sure, but it doesn't have to always be like this.
And not all limits make you think, some are just practical because an upper bound is often nice to have. Eg. 255 characters per file name is probably a relief for on-disk file system formats.
Because of C's design.
It's not a limitation, but an explicit choice. There were alternatives, but they were explicitly discarded.
Maybe you will.
Because you might discover that such design decision makes scripting (and programming in general) easier and faster, for example.
What makes you more free, spaces in filenames or easier programming?
That's an UI issue in the software you use to organise your music.
Use an higher level UI if you don't want to mess with such low level details.
You don't need a special tool, you want one. Both using spaces in file names and not using them have trade offs.
Without you have easier textual interactions.
With you have easier to write nice graphical file managers.
Depending on what you care more about you move between the two.
i use /bin/ash
to manage my music files and its fine
Like, just having a standard lightweight container format would be enough, so you don't end up writing a parser for every tool.
TSV is nice because you can write an en/decoder in an hour (at most, if your C is rusty. more like 15 minutes otherwise) and it gets you enough structure without sacrificing readability
pure S-expressions are also super easy to parse, just need like... a way to do recursion??? i think? it's been a while since I wrote one (in Lua) but that too only took like 20 m.
@xj9 @grainloom
Basically it's a matter of habits.
You are used to operating systems that care much more about looking simple that about being simple.
But sometimes few consistent constraints can make a system more predictable and easy to compose.
@Shamar because they are useful
the question is, why would tools use space as a primary field separator
@Shamar like, if you wanna give files meaningful names, you're gonna use spaces
hyphens don't cut it (they have different semantic meaning in language) and underscores are irritating to type and look ugly
a concrete example is my music library. why should i need to do special formatting on artist, album, and track names? a path like ~/Music/mix/Goldroom/OtoΓ±o Mix 2014.mp3
is perfectly acceptable imo
Nice example. π
Use underscore.
If you like to SEE space instead of underscore into you file manager GUI configure your file manager GUI that way.
But since files are acted upon through commands in a textual interface that use spaces, spaces should not be allowed.
Actually if you completely remove text from computers, you won't have such problems with spaces.
As an alternative one might consider to replace the space with a different character in the input of textual interfaces (aka shells).
@Shamar @xj9
Or just.... force users to use string literals for strings? And let unquoted strings mean something else?
I mean, you can't seriously say "but that's harder to learn" when we have just demonstrated how many problems it leads to.
If kids can learn Python in a week, programmers can bear with a teeeensy bit more syntax in their shells.
String literals mean escape rules.
And sometimes they are hard to get right for programmers too.
Every single time programmers are too shy to impose a simple restriction to users' input (or customers' will), they add to the pile of crap another source of complexity.
@xj9
@Shamar idk, read it in some manpage the other day, not sure which
but similar problems apply to a lot of the system, eg. how basically nothing can handle spaces in file names
(hot take, $ifs should only contain tab and newline, or better yet, there should be no $ifs)
