curated package predated the standard errors package introduced in
go1.13
the standard package does a better job of what curated attempted to do
the change of package also gave me a opportunity to clean up the error
messages a little bit
now takes into consideration the attached terminal. added
IsRealTerminal() to terminal.Input interface to support this
reworked script package error messages
removed all messages from errors package. the strings are now hard coded
in place. the original reason for extracting the error strings like that
was (a) for redundancy and (b) for localisation possibilities. However,
in reality there is not much redundancy and since the project started
the scope of localisation is much larger (particularly due to the
addition of a GUI)
this is the first step. the next step is to remove the errors package
altogether. recent additions to Go mean that the functionality of the
errors package is no longer required. moreover, the original idea for
the errors package functions turns out not to have been as useful as
first appeared (the Error() functionality which makes sure no repeating
sub-strings occur is probably better achieved with static tooling).
one idea that comes from this which is quite interesting is the idea of
a curated error. that is, any error that has been "wrapped" as some
'generic' type. the IsAny() function in the errors package effectively
serves this purpose. we use that in one place in the input loop of the
debugger. not strictly necessary but nice to have so it would ideal
if we could remove the errors package but keep that idea.
the note about historical versions also being covered wasn't strictly
needed and was ugly. the LICENCE being in the root file from the very
first commit is sufficient.
