Dotaz: cvs diff -r tag:*date*

[Hynek (Pichi) Vychodil]

V jakém formátu se v kládá date do volby -r v příkazu cvs diff, annotate a podobných? Manuál bohužel o této drobnosti cudně mlčí nebo mlží. Viz.

-r tag[:date]

Compare with revision specified by tag or, when date is specified and tag is a branch tag, the version from the branch tag as it existed on date. Zero, one or two `-r' options can be present. With no `-r' option, the working file will be compared with the revision it was based on. With one `-r', that revision will be compared to your current working file. With two `-r' options those two revisions will be compared (and your working file will not affect the outcome in any way).

One or both `-r' options can be replaced by a `-D date' option, described above.

Zkoušel jsem namátkou:

cvs diff: Date 2006.08.12.22.00.00 refers to a dead (removed) revision in file `AFM.pm'.

A milión dalších kombinací co už jsem zkoušel. Jak je vidět kombinací -r a -D se ke kýženému stavu nemůžu dostat (demonstrováno na souborech které existují pouze v této větvi) a na správnou syntaxi -r tag:date nmůžu přijít.

Už jsem se radoval a nic. Ten dokument je o policy jak vytvářet jméno tagu. Bohužel to neodpovídá na otázku jak formátovat tu část za dvojtečkou. Ani formát tam použitý to není:

$ cvs diff -r new_afm_solve-b':20060814'
cvs [diff aborted]: tag `new_afm_solve-b:20060814' must not contain the characters `$,.:;@'
