refactor: Clean up messy strformat and bilingual

ryanofsky commented at 12:19 pm on October 11, 2024: contributor

This PR cleans up string formatting in the codebase so other PRs adding compile time checking can be simpler and easier to review (specifically #30928, #31061, #31074, and #31149).

Currently these PRs are hard to review because in addition to changing formatting APIs, they have to update callers that are using the API’s in unusual ways. Clean up these callers now so later PRs can be simpler. Specifically:

Use string literals instead of std::string format strings to enable more compile-time checking.
Avoid using translated strings as format strings. Use originals so they can by checked at compile time.
Favor emplace_back over push_back when appending Untranslated strings.
Favor Untranslated(strprintf(...)) over strprintf(Untranslated(...), ...) for consistency and to prevent translated and untranslated strings from being unintentionally combined.

I still don’t think this is correct. You are using + to concatenate Untranslated and _() (translated), possibly mixing English strings with non-English ones. Also, this compiles, so there are no compile-time checks preventing the “mix”.

There is nothing in this commit message (19f49f138c4756b5219e715d8749d15be07e2c81) which mentions mixing English or non-english strings.

As a whole, this PR is updating around 30 strprintf calls to be more readable and consistent and to, yes, make 27 of them now trigger compiler errors if there is an attempt to pass a bilingual_str as a strprintf parameter, preventing accidental mixing English and non-english strings.

Obviously it should not be compile error to intentionally mix translated and non-translated strings, and this is still possible with +, which the code is now using in 3 more places.

Sorry for being unclear. The commit title says

“refactor: Use + instead of strformat to concatenate Untranslated strings”.

It should say:

“refactor: Use + instead of strformat to concatenate bilingual strings, which may be Untranslated or translated (_)”

I don’t mind the changes here, but I don’t think the motivation is correct and it seems verbose and misleading.

I don’t think it matters much whether this is merged or not, but you could just replace the motivation with:

“This replacement makes the implementation of some compile-time checks in the future easier. Also, it makes the code a bit more consistent in that Untranslated isn’t allowed as a format-string anymore, only plain std::strings, or translated strings. The downside would be that developers may have to use operator+ more often, making it a bit harder to write code involving formatting of (un)translated strings. However, if it becomes too annoying, the changes here should be easy to revert.”

re: #31072#pullrequestreview-2362888700

I don’t mind the changes here, but I don’t think the motivation is correct and it seems verbose and misleading.

I don’t know what was misleading, but I rewrote description and will paste old text in comment below in case it’s useful. Sorry for verbosity, I like to think by writing, but it doesn’t always result in the most helpful thing to read.

scripted-diff: Replace strprintf(Untranslated(…)) with Untranslated(strprintf(…))

This PR is just a scripted-diff replacing strprintf calls like:

0strprintf(Untranslated("Error parsing command line arguments: %s"), error))

with:

0Untranslated(strprintf("Error parsing command line arguments: %s", error))

Currently code is inconsistent and uses a mix of both styles, but second style is better because:

It scans more cleanly. It is easier to read the strprintf call, and easier to think about because the whole string, not just one part, is passed to Untranslated() to convert from std::string to bilingual_str.
It lets the compiler prevent janky UX where non-english fragments are inserted into english messages. One potential case where a bilingual_str was substituted into an english format string is fixed in the first commit of this PR.
It doesn’t waste work formatting the same string twice.
It simplifies the translation API after #31061. Instead of Untranslated() function sometimes returning a bilingual_str, other times returning a Translatable<false> struct with a different set of fields, it can stay the way it is and simply convert std::string to bilingual_str.
It simplifies the implementation of #31061, allowing two commits faf71be89ad9d07c0848d13da51fc71c11395984 and fae6acacc0216aa07f5a4a0ee75fbade620d7023 to be dropped, as well as other changes in other commits.

One potential downside of this change, pointed out #31061 (review), is that after this PR if you want to change an untranslated format string to a translated one (or vice versa), you will have to to add _() around the format string and drop Untranslate() around the formatted string, instead of just literally replacing Untranslated with _. But I think this is good, because the change is still easy to make, and it lets you consider whether other parts of the strprintf call also should switch to translated strings to avoid jank of non-translated messages being embedded in translated strings (or vice versa).

An alternative to this PR could be a scripted-diff switching all code to use strprintf(Untranslated(...)) instead of Untranslated(strprintf(...)). I think this alternative would also be an improvement over the status quo, since it would also make the code more consistent, also simplify #31061, and also avoid needing to overload Untranslated() there to return objects with incompatible types. But I think this PR is better than the alternative for reasons 1-3 above, and better because it lets Untranslated remain a simple one-liner that converts a std::string to bilingual_str and is not involved in formatting.

Note: The scripted diff in this PR only removes current strprintf(Untranslated(...)) calls without adding enforcement to prevent new ones. But adding enforcement is easy with #31061 and simplifies that PR by dropping support for the strprintf(Untranslated(...)) syntax.

Right now, it may not be used extensively, or only used to concatenate two blobs. However, I can imagine that in the future someone may want to write strprintf(Untranslated("<a href="...">%s</a><br>%s<br>"), ...) to format some bilingual strings into html, which would be a bit more verbose by doing with plenty of +.

Not saying that this is something common, but I wanted to mention it.

ryanofsky commented at 7:21 pm on October 29, 2024:

re: #31072 (review)

Thanks, we also talked about this offline and I agree that strprintf can often be nicer than concatenation for building strings, but I think this approach doesn’t work very well for untranslated bilingual strings. For example in the HTML case, you would probably only want to format the translated strings as HTML, not both translated and original strings. I think the downsides of supporting untranslated format strings outweigh the upsides. (Downsides being having two inconsistent ways of formatting the same strings, having a more complicated interface, and potential for introducing mixed translation bugs.)

refactor: Avoid concatenation of format strings

Instead just concatenate already formatted strings. This allows untranslated
format strings to be checked at compile time now, and translated format strings
to be checked at compile time in #31061.

refactor: Pick translated string after format

refactor: Use + instead of strformat to concatenate translated & untranslated strings

This change removes two strprintf(Untranslated...) calls so support for
formatting untranslated strings can be dropped, and translation API can be
simpler and more type safe. The following scripted-diff commit removes all
remaining strprintf(Untranslated...) calls.

Additionally, using + and += makes code a little shorter and makes it more
obvious when messages are being joined together. And it makes code more
type-safe because + unlike strprintf only works on strings of the same type,
and makes it less likely english strings and bilingual strings will be
unintentionally combined.

This makes code more consistent and makes it easier to add compile-time checking to

using Untranslated() to create the format string, so the Untranslated()
function will not need to get involved in formatting.

I think the advantage of your suggestion is avoids repeating str. So I’d probably write the code that way if str was something more complicated than a single variable.

I think the story of the current version is “this returns message plus a list of details if any” and the story of the suggested version is “this returns a message plus a suffix, which can be empty or can be a list of details” and I think both are reasonable, but the current version does seem a little simpler to me and more similar to current code.

Good catch! Thanks for the close reading. The commit description 75643fd325748f8b81dc78edfc1266f47990f9b4 was wrong when it said that this change was needed to let the scripted diff compile. That comment is only true for previous commit d392068d7257e0cb8ca8e95fcb5e504b4b4f2839, not this one. Fixed the description now.

About the Result class, it intentionally does not have a bilingual_str accessor. The goal of the Result class is to provide meaningful error messages to users when operations fail. While useful error messages can be a represented by a single bilingual_str they can also be represented by a lists of errors and warnings, or lists of errors with details for debugging, or other richer ways that can be shown in GUIs or returned as json. In #25665 the Result class is changed to allow custom error representations and change the default representation to support multiple errors and warnings. Making the ErrorString a nonmember function instead of a member function makes this more easily possible because the Result class only needs to be concerned with representing errors and not formatting them.

Right, I think it would be bad if changing or tweaking the name of the program required newly translating “The %s developers” with the new name of the program hardcoded.

👍, it’s obvious that the Section name is m_name, not m_file.

nit: it seems to me in other cases we’re using %d instead of %i (if you edit again, consider simplifying to %d which seems to have fewer surprises): https://github.com/bitcoin/bitcoin/blob/master/src/init.cpp#L986

re: #31072 (review)

IIUC, linter is just very simple and doesn’t expand macros. If I remove this line running the linter shows:

I have basically redone the change locally to understand it better and mostly left questions or nits, I’m fine with merging as is
