So in the later commits, we plan to add this feature to ref-filter. Refactor `format_sanitized_subject()`, so it can be reused in ref-filter.c for adding new modifier `sanitize` to "subject" atom. Currently, the loop inside `format_sanitized_subject()` runs until `\n` is found. But now, we stored the first occurrence of `\n` in a variable `eol` and passed it in `format_sanitized_subject()`. And the loop runs upto `eol`. But this change isn't sufficient to reuse this function in ref-filter.c because there exist tags with multiline subject. It's wise to replace `\n` with ' ', if `format_sanitized_subject()` encounters `\n` before end of subject line, just like `copy_subject()`. Because we'll be only using `format_sanitized_subject()` for "%(subject:sanitize)", instead of `copy_subject()` and `format_sanitized_subject()` both. So, added the code: ``` if (char == '\n') /* never true if called inside pretty.c */ char = ' '; ``` Now, it's ready to be reused in ref-filter.c Mentored-by: Christian Couder Mentored-by: Heba Waly Signed-off-by: Hariom Verma --- pretty.c | 24 +++++++++++++++--------- 1 file changed, 15 insertions(+), 9 deletions(-) diff --git a/pretty.c b/pretty.c index 2a3d46bf42..8d08e8278a 100644 --- a/pretty.c +++ b/pretty.c @@ -839,24 +839,29 @@ static int istitlechar(char c) (c >= '0' && c <= '9') || c == '.' || c == '_'; } -static void format_sanitized_subject(struct strbuf *sb, const char *msg) +static void format_sanitized_subject(struct strbuf *sb, const char *msg, size_t len) { + char *r = xmemdupz(msg, len); size_t trimlen; size_t start_len = sb->len; int space = 2; + int i; - for (; *msg && *msg != '\n'; msg++) { - if (istitlechar(*msg)) { + for (i = 0; i < len; i++) { + if (r[i] == '\n') + r[i] = ' '; + if (istitlechar(r[i])) { if (space == 1) strbuf_addch(sb, '-'); space = 0; - strbuf_addch(sb, *msg); - if (*msg == '.') - while (*(msg+1) == '.') - msg++; + strbuf_addch(sb, r[i]); + if (r[i] == '.') + while (r[i+1] == '.') + i++; } else space |= 1; } + free(r); /* trim any trailing '.' or '-' characters */ trimlen = 0; @@ -1155,7 +1160,7 @@ static size_t format_commit_one(struct strbuf *sb, /* in UTF-8 */ const struct commit *commit = c->commit; const char *msg = c->message; struct commit_list *p; - const char *arg; + const char *arg, *eol; size_t res; char **slot; @@ -1405,7 +1410,8 @@ static size_t format_commit_one(struct strbuf *sb, /* in UTF-8 */ format_subject(sb, msg + c->subject_off, " "); return 1; case 'f': /* sanitized subject */ - format_sanitized_subject(sb, msg + c->subject_off); + eol = strchrnul(msg + c->subject_off, '\n'); + format_sanitized_subject(sb, msg + c->subject_off, eol - (msg + c->subject_off)); return 1; case 'b': /* body */ strbuf_addstr(sb, msg + c->body_off);
