* color: Handle bfs_check_capabilities error code (-1) in cpath_has_capabilitiesJody Frankowski2024-10-311-1/+1
| | | | | | | | | | | On non-Linux systems, bfs_check_capabilities always returned -1, so cpath_has_capabilities would always return true. If bfs was called with an LS_COLORS containing the `ca` statement, e.g. `ca=30;41`, bfs would color ALL the files. While including the `ca` statement in LS_COLORS on non-Linux systems is unusual, this is not an error and is a valid use-case (e.g. Using GNU ls or lsd). Fixes: 1520d4d3 ("color: Don't color files like directories on ENOTDIR")
* dstring: Add an infallible dstrshrink() functionTavian Barnes2024-10-171-2/+2
| | | | And mark the fallible ones with _nodiscard.

* color: Fix an infinite loop colorizing some invalid pathsTavian Barnes2024-10-131-8/+11
| | | | | | | | | | | | | | Previously, given $ touch file $ ln -s file/file notdir $ bfs notdir/file bfs would loop forever when printing the error message, since it expected stripping the trailing slash from "notdir/" to fix the ENOTDIR error, but the broken symlink still gave the same error. Fixes: b4c3201 ("color: Only highlight the trailing slash on ENOTDIR")

* color: Fix an assertion failure with embedded NUL bytesTavian Barnes2024-10-021-0/+10
| | | | | | | | | | | | | Leading NUL bytes (e.g. `*\0.gz=...`) could cause us to insert a non-prefix-free set of strings into the case-insensitive extension trie, which would lead to crashes like bfs: trie_split@src/trie.c:538: Assertion failed: `key_nibble != rep_nibble` and OOB accesses to trie leaf keys. Fix it by ignoring those extensions, since filenames cannot contain NUL bytes. Fixes: 08030aea ("color: Delay the case_sensitive decision")

* build: Move feature test macros to prelude.hTavian Barnes2024-08-281-1/+0
| | | | | | This replaces the explicit CPPFLAGS list in flags.mk with just `-include src/prelude.h`, shortening our compiler command lines and allowing them to be easily documented.

* Cast AT_FDCWD to int for comparisonsTavian Barnes2024-05-171-1/+1
| | | | | Some platforms define AT_FDCWD to a constant like 0xFFFAFDCD that gets typed as an unsigned int.

* color: New API to check if stat() is necessaryTavian Barnes2024-02-061-0/+5
|
* expr: Make expressions variadicTavian Barnes2024-01-071-21/+18
| | | | | | | | | Rather than only unary/binary expressions, we now support an arbitrary number of children. The optimizer has been re-written almost completely and now supports optimal reordering of longer expression chains, rather than just arm-swapping. Fixes #85.

| | | | | | | | | Since coreutils 9.2, ls does case-sensitive extension matching if the same extension is capitalized differently in $LS_COLORS. Implement the same logic. Link: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=33123 Link: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=9086
