There's probably more that can be said, but I thought it might be helpful to put something here about how to access elements of a list for folks coming from more or less any other programming language. If this is rarely used, it might be nice to add to the documentation something about why it's rarely used.
Commit d536c57e87 inadvertedly broke build and
installation of all non-autogenerated manual pages (in particular, all the ones
documenting the stable CLI), by moving the definition of the man-pages variable
in doc/manual/local.mk after its usage in mk/lib.mk. Move including the former
earlier so that the correct order is restored.
how the different invocations relate to each other seems be
confusing, which is relatable because one has to wire it up in your head
while reading. an explicit reference should make it unambiguous and
easier to notice due to links being highlighted.
autoconf authors apparently decided that setting `-O2` by default was a good idea. I disagree, and Nix has its own way of deciding that (with `OPTIMIZE={0,1}`). Explicitly set `CFLAGS` and `CXXFLAGS` in the configure script to disable that behaviour.
Fix#9965
When I started contributing to Nix, I found the mix of definitions and
names in `fmt.hh` to be rather confusing, especially the small
difference between `hintfmt` and `hintformat`. I've renamed many classes
and added documentation to most definitions.
- `formatHelper` is no longer exported.
- `fmt`'s documentation is now with `fmt` rather than (misleadingly)
above `formatHelper`.
- `yellowtxt` is renamed to `Magenta`.
`yellowtxt` wraps its value with `ANSI_WARNING`, but `ANSI_WARNING`
has been equal to `ANSI_MAGENTA` for a long time. Now the name is
updated.
- `normaltxt` is renamed to `Uncolored`.
- `hintfmt` has been merged into `hintformat` as extra constructor
functions.
- `hintformat` has been renamed to `hintfmt`.
- The single-argument `hintformat(std::string)` constructor has been
renamed to a static member `hintformat::interpolate` to avoid pitfalls
with using user-generated strings as format strings.
As discussed in the last Nix team meeting (2024-02-95), this method
doesn't belong because `CanonPath` is a virtual/ideal absolute path
format, not used in file systems beyond the native OS format for which a
"current working directory" is defined.
Progress towards #9205
Pretty-print values in the REPL by printing each item in a list or
attrset on a separate line. When possible, single-item lists and
attrsets are printed on one line, as long as they don't contain a nested
list, attrset, or thunk.
Before:
```
{ attrs = { a = { b = { c = { }; }; }; }; list = [ 1 ]; list' = [ 1 2 3 ]; }
```
After:
```
{
attrs = {
a = {
b = {
c = { };
};
};
};
list = [ 1 ];
list' = [
1
2
3
];
}
```
