* cll command to list all nine.Kaz Kylheku2024-02-011-1/+9
| | | | | | | | * cdlog.sh (cdlog): Take -l option to print all nine directories in the FIFO. (cll): New alias, for cdlog -l. * README.md: Documented.
* Don't use global x for looping.Kaz Kylheku2024-02-011-2/+2
| | | | | | * cdlog.sh (cdlog.mcd): Oh boy; we have used our own $x variable as a loop dummy. Switch to i which is set up as local.
* mcd: scroll-region-friendly line clearing.Kaz Kylheku2024-02-011-1/+4
| | | | | | | | | * cdlog.sh (cdlog.mcd): Going up ten lines with \e[10A and then clearing to the end of screen with \e[J is unfriendly when the user has a scroll-protected region at the bottom showing a status line. Instead, let us go up one line at a time ten times with \e[A, and clear each line to end of line with \e[K.
* Use range expansion.Kaz Kylheku2024-02-011-1/+1
| | | | * cdlog.sh (cdlog.mcd): Replace 1 2 3 ... 9 with {1..9}.
* New: mcd, mcs: menu-based cd and cs.Kaz Kylheku2024-01-251-0/+37
| | | | | | | * cdlog.sh (cdlog.mcd): New function. (mcd, mcs): New aliases. * README.md: Documented.
* cdlog: simplify prefixes.Kaz Kylheku2024-01-251-5/+6
| | | | | * cdlog.sh (cdlog): Just print numeric indices before the paths.
* print new PWD in pd and cs.Kaz Kylheku2024-01-251-0/+3
| | | | | * cdlog.sh (cdlog.rot, cdlog.pop): Print new current directory if change successful.
* Add cl alias for cdlog.Kaz Kylheku2024-01-231-0/+1
|
* Improve initialization.Kaz Kylheku2024-01-191-8/+6
| | | | | | * cdlog.sh (toplevel): Ensure that c1 exists, so that the init code doesn't access a nonexistent c1. Condense the assignments in the init block.
* Reduce repeated code.Kaz Kylheku2024-01-191-13/+7
| | | | | | * cdlog.sh (cdlog.rot): Eliminate repeated code, distinguishing different parts with a flag indicating the first loop iteration.
* Generalize swap to rotate.Kaz Kylheku2024-01-191-18/+28
| | | | | | | | * cdlog.sh (cdlog.swap): Function removed. (cdlog.rot): New function. (cs): Alias now points to cdlog.rot. * README.md: Updated.
* Remove repetitive code from cdlog.swap.Kaz Kylheku2024-01-191-44/+24
| | | | | | * cdlog.sh (cdlog.args): New function. (cdlog.swap): Use array to do swap in one case.
* Minor code tidying.Kaz Kylheku2024-01-191-17/+9
| | | | | | * cdlog.sh (cdlog.chdir, cdlog.swap): Condense assignment block to fewer lines. (toplevel): Move "cs" alias below.
* cs takes argument; swapping behavior removed from cd.Kaz Kylheku2024-01-191-18/+74
| | | | | | | | * cdlog.sh (cdlog.chdir): No specifial behavior when $PWD equals $c1. (cdlog.swap): Swapping behavior implemented here now, with optional numeric argument to swap with entries other than first.
* Change semantics of swap implementation.Kaz Kylheku2024-01-181-4/+4
| | | | | | * cdlog.sh (cdlog.chdir): When the user changes to $c1, let's not involve $c2 but just effectively exchange the current working directory and $c1.
* Change naming of functions to dot notation.Kaz Kylheku2024-01-181-8/+8
