From bad56744355b2e212797d05ee0ebd763cc8211de Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Sat, 27 Aug 2016 23:07:04 -0500 Subject: Remove some redundancy and unnecessary xprintf(). (We should use xprintf and similar to flush and check if stdout went away once per line. No point flushing partway through a line, so in ls only use it on things outputting a newline char.) --- toys/posix/ls.c | 49 +++++++++++++++++++++---------------------------- 1 file changed, 21 insertions(+), 28 deletions(-) (limited to 'toys') diff --git a/toys/posix/ls.c b/toys/posix/ls.c index c7e2da5a..73c4b7b3 100644 --- a/toys/posix/ls.c +++ b/toys/posix/ls.c @@ -20,7 +20,7 @@ config LS -c use ctime for timestamps -d directory, not contents -i inode number -k block sizes in kilobytes -p put a '/' after dir names -q unprintable chars as '?' - -s size (in blocks) -u use access time for timestamps + -s storage used (512 byte units) -u use access time for timestamps -A list all files but . and .. -H follow command line symlinks -L follow symlinks -R recursively list files in subdirs -F append /dir *exe @sym |FIFO -Z security context @@ -126,6 +126,12 @@ static int numlen(long long ll) return snprintf(0, 0, "%llu", ll); } +static int print_with_h(char *s, long long value, int units) +{ + if (toys.optflags&FLAG_h) return human_readable(s, value*units, 0); + else return sprintf(s, "%lld", value); +} + // Figure out size of printable entry fields for display indent/wrap static void entrylen(struct dirtree *dt, unsigned *len) @@ -148,18 +154,10 @@ static void entrylen(struct dirtree *dt, unsigned *len) // cheating slightly here: assuming minor is always 3 digits to avoid // tracking another column len[5] = numlen(dev_major(st->st_rdev))+5; - } else if (flags & FLAG_h) { - human_readable(tmp, st->st_size, 0); - len[5] = strwidth(tmp); - } else len[5] = numlen(st->st_size); + } else len[5] = print_with_h(tmp, st->st_size, 1); } - if (flags & FLAG_s) { - if (flags & FLAG_h) { - human_readable(tmp, st->st_blocks*512, 0); - len[6] = strwidth(tmp); - } else len[6] = numlen(st->st_blocks); - } else len[6] = 0; + len[6] = (flags & FLAG_s) ? print_with_h(tmp, st->st_blocks, 512) : 0; len[7] = (flags & FLAG_Z) ? strwidth((char *)dt->extra) : 0; } @@ -360,10 +358,8 @@ static void listfiles(int dirfd, struct dirtree *indir) } totpad = totals[1]+!!totals[1]+totals[6]+!!totals[6]+totals[7]+!!totals[7]; if ((flags&(FLAG_h|FLAG_l|FLAG_o|FLAG_n|FLAG_g|FLAG_s)) && indir->parent) { - if (flags&FLAG_h) { - human_readable(tmp, blocks*512, 0); - xprintf("total %s\n", tmp); - } else xprintf("total %llu\n", blocks); + print_with_h(tmp, blocks, 512); + xprintf("total %s\n", tmp); } } @@ -427,14 +423,11 @@ static void listfiles(int dirfd, struct dirtree *indir) } width += *len; - if (flags & FLAG_i) - xprintf("%*lu ", totals[1], (unsigned long)st->st_ino); + if (flags & FLAG_i) printf("%*lu ", totals[1], (unsigned long)st->st_ino); if (flags & FLAG_s) { - if (flags & FLAG_h) { - human_readable(tmp, st->st_blocks*512, 0); - xprintf("%*s ", totals[6], tmp); - } else xprintf("%*lu ", totals[6], (unsigned long)st->st_blocks); + print_with_h(tmp, st->st_blocks, 512); + printf("%*s ", totals[6], tmp); } if (flags & (FLAG_l|FLAG_o|FLAG_n|FLAG_g)) { @@ -469,15 +462,15 @@ static void listfiles(int dirfd, struct dirtree *indir) if (S_ISCHR(st->st_mode) || S_ISBLK(st->st_mode)) printf("% *d,% 4d", totals[5]-4, dev_major(st->st_rdev), dev_minor(st->st_rdev)); - else if (flags&FLAG_h) { - human_readable(tmp, st->st_size, 0); - xprintf("%*s", totals[5]+1, tmp); - } else printf("% *lld", totals[5]+1, (long long)st->st_size); + else { + print_with_h(tmp, st->st_size, 0); + printf("%*s", totals[5]+1, tmp); + } // print time, always in --time-style=long-iso tm = localtime(&(st->st_mtime)); strftime(tmp, sizeof(tmp), "%F %H:%M", tm); - xprintf(" %s ", tmp); + printf(" %s ", tmp); } else if (flags & FLAG_Z) printf("%-*s ", (int)totals[7], (char *)sort[next]->extra); @@ -488,7 +481,7 @@ static void listfiles(int dirfd, struct dirtree *indir) ss = sort[next]->name; crunch_str(&ss, INT_MAX, stdout, TT.escmore, crunch_qb); - if (color) xprintf("\033[0m"); + if (color) printf("\033[0m"); if ((flags & (FLAG_l|FLAG_o|FLAG_n|FLAG_g)) && S_ISLNK(mode)) { printf(" -> "); @@ -510,7 +503,7 @@ static void listfiles(int dirfd, struct dirtree *indir) // Pad columns if (flags & (FLAG_C|FLAG_x)) { curcol = colsizes[curcol]-(*len)-totpad; - if (curcol < 255) xprintf("%s", toybuf+255-curcol); + if (curcol < 255) printf("%s", toybuf+255-curcol); } } -- cgit v1.2.3
