questions:
|
|
|
|
add some comments?
|
|
|
|
why is prefix used in doConfigure ? shouldn't that be out?
|
|
|
|
don't think toSrcDir should cd to the directory.
|
|
I'd prefer cd `toSrcDir xx.tar.gz`
|
|
Then you can use it to unpack files
|
|
|
|
suggestion:
|
|
deps before text? why?
|
|
It's kind of documentation and much less lines most of the time ?
|
|
|
|
remove noDepEntry, FullDepEntry, PackEntry all together and use { ... } ?
|
|
you only have to remember two words: text and deps which isn't hard
|
|
using noDepEntry FullDepEntry PackEntry you'll have to remember 3 words and argument order
|
|
You just have to learn it once.. ?
|
|
|
|
no way to override steps ?
|
|
|
|
separate settings from dep entries
|
|
(eg patchFlags / forceShare, patches) to get a better overview ? )
|
|
|
|
envAdderInner: What about a small example? It took quite some time to understand how to use it
|
|
eg envAdderInner "" "A" "B" "C" "D" null results in
|
|
echo export A="$A:B";
|
|
echo export C="$C:D";
|
|
does'nt handle the env has been empty don't add delimiter case
