Merge pull request #205557 from ncfavier/concatLines 
lib/strings: add `concatLines`

Robert Hensing d103811173 lib.isStringLike: Remove use of list 
In the current implementation of Nix, this list would be allocated
over and over. Iirc pennae tried to optimize static list allocation,
but gained no significant performance improvement.

Robert Hensing 23c25d5231 lib.strings.isConvertibleWithToString: Refactor to reuse isStringLike 2022-12-31 01:33:47 +01:00
Robert Hensing 834f0d660a lib.strings: isMoreCoercibleString -> isConvertibleWithToString 
Yes, this function name is inconveniently long, but it is important
for the name to explicitly reference the function and not be mistaken
for the implicit string conversions, which only happen for a smaller
set of values.

figsoda 695d4bc76b lib: fix typos 2022-12-17 18:59:29 -05:00
Artturin 05a2dfd674 lib.replaceChars: warn about being a deprecated alias 
replaceStrings has been in nix since 2015(nix 1.10)

so it is safe to remove the fallback

lib/strings: add concatLines 
Like `unlines` from Haskell.

The aim is to replace the `concatStringsSep "\n"` pattern for generated
files, which doesn't add a final newline.

lib.strings: fix negative number handling for toInt and toIntBase10 
The previous version would be unstable due to an input validation regex
not expecting a '-' in front of the number.

lib/strings: simplify splitString 
There's no need to use `unsafeDiscardStringContext` since
ee7fe64c0a
(Nix 1.8).

Also the separator can't have a context since `builtins.split` would fail, so
we can assume it doesn't.

Merge pull request #173949 from jacoblambda/fix-toInt-zero-padding 
lib: add strings.toIntBase10 to parse zero-padded strings
 2022-10-24 13:22:42 +02:00
Guillaume Girol 956e35d0b1 lib.normalizePath: the empty string is not a valid regex on darwin 
presumably due to using libc++'s regex lib instead of libstdc++ on linux

polykernel de81edf6ef lib/strings: fix infinite recursion on concatStringsSep fallback 
The current implementation of the concatStringsSep fallback references
concatStrings whcih is just a partial application of concatStringsSep,
forming a circular dependency. Although this will almost never be
encountered as (assuming the user does not explicitly trigger it):
  1. the or operator will short circuit both in lazy and strict
     evaluation
  2. this can only occur in Nix versions prior to 1.10
     which is not compatible with various nix operations as of 2.3.15

However it is still important if scopedImport is used or the builtins
have been overwritten. lib.foldl' is used instead of builtins.foldl'
as the foldl' primops was introduced in the same release as concatStringsSep.

strings.nix: Fix overly monomorphic type signature comments

sternenseemann f39a5c4e50 lib/strings: forbid lists in isStorePath 
When a list is passed to isStorePath this is most likely a mistake and
it is therefore better to just return false. There is one case where
this theoretically makes sense (if a list contains a single element for
which isStorePath elem), but since that case is also probably seldomly
intentional, it may save someone from debbuging unclear evaluation
errors.

sternenseemann 326d0970e0 lib/strings: fix example for isStorePath 
Since it checks if dirOf x is the nix store dir, a trailing slash will
break this check and make it return false.

Alex Brandt ff1700feda lib/string: drop redundant string in description of toInt. 
Describing the string argument as a string is redundant and not needed
to describe what this function does.

Alex Brandt 4a5cb363ae lib/strings: fix typo in example 
The example refers to a snake_case function name but Nix uses camelCase
function names.  This ensures the example is correct for the given
function.
