* string-util: Add startswith_strv()Daan De Meyer2023-04-201-0/+5
| | | | | | This is the function version of STARTSWITH_SET(). We also move STARTSWITH_SET() to string-util.h as it fits more there than in strv.h and reimplement it using startswith_strv().
* string-util: add strstrafter()Lennart Poettering2023-04-141-0/+12
| | | | | | | | | strstrafter() is like strstr() but returns a pointer to the first character *after* the found substring, not on the substring itself. Quite often this is what we actually want. Inspired by #27267 I think it makes sense to add a helper for this, to avoid the potentially fragile manual pointer increment afterwards.

* string-util: add new strdupcspn()/strdupspn()Lennart Poettering2023-01-201-0/+3
| | | | | | | | These combine strndup() + strspn()/strcspn() into one. There are a bunch of strndupa() calls that could use similar treatment (or should be converted to strdup[c]spn(), but this commit doesn't bother with that.
* string-util: rework empty_to_null() to not change "const" qualifier of inputLennart Poettering2022-12-211-3/+12
| | | | | | | | This changes the definition from enpty_to_null() so that we are still typesafe (i.e. only accept strings) but do not drop (or add) any const to the returned string that wasn't also on the input. Inspired by: https://github.com/systemd/systemd/pull/25805/commits/3196e2996f613a2e3568a791c503306b7c58d593

* fundamental: move several macros and functions into src/fundamental/Yu Watanabe2021-02-091-47/+1
| | | | | | | | | | sd-boot has a copy of a subset of codes from libbasic. This makes sd-boot share the code with libbasic, and dedup the code. Note, startswith_no_case() is dropped from sd-boot, as - it is not used, - the previous implementation is not correct, - gnu-efi does not have StrniCmp() or so.

* Add string_contains_word_strv()Zbigniew Jędrzejewski-Szmek2020-09-041-1/+5
| | | | | | I had to move STRV_MAKE to macro.h. There is a circular dependency between extract-word.h, strv.h, and string-util.h that makes it hard to define the inline function otherwise.
* basic: add string_contains_word()Zbigniew Jędrzejewski-Szmek2020-09-041-0/+1

* Rework cmdline printing to use unicodeZbigniew Jędrzejewski-Szmek2019-05-221-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | The functions to retrieve and print process cmdlines were based on the assumption that they contain printable ASCII, and everything else should be filtered out. That assumption doesn't hold in today's world, where people are free to use unicode everywhere. This replaces the custom cmdline reading code with a more generic approach using utf8_escape_non_printable_full(). For kernel threads, truncation is done on the parenthesized name, so we'll get "[worker]", "[worker…]", …, "[w…]", "[…", "…" as we reduce the number of available columns. This implementation is most likely slower for very long cmdlines, but I don't think this is very important. The common case is to have short commandlines, and should print those properly. Absurdly long cmdlines are the exception, which needs to be handled correctly and safely, but speed is not too important. Fixes #12532. v2: - use size_t for the number of columns. This change propagates into various other functions that call get_process_cmdline(), increasing the size of the patch, but the changes are rather trivial.
* shared/utmp-wtmp: silence gcc warning about strncpy truncationZbigniew Jędrzejewski-Szmek2019-05-071-0/+6
| | | | | | | | | Unfortunately the warning must be known, or otherwise the pragma generates a warning or an error. So let's do a meson check for it. Is it worth doing this to silence the warning? I think so, because apparently the warning was already emitted by gcc-8.1, and with the recent push in gcc to catch more such cases, we'll most likely only get more of those.
* basic: add new helper call empty_or_dash_to_null()Lennart Poettering2019-04-081-0/+4
| | | | | We have a function like this at two places already. Let's unify it in one generic location and let's port a number of users over.
* tree-wide: introduce empty_or_dash() helperLennart Poettering2019-04-081-0/+6
| | | | | At quite a few places we check isempty() || streq(…, "-"), let's add a helper to simplify that, and replace that by a single function call.
