|
# procedure in the package is made.

|
# was successfully rocessed is printed out. Additionally,

|
# if processing of a file failed a message is printed.
|
||||||

# the pattern. Used to handle DLLs that depend on
|
||||||
|
# other packages during their Init procedure.

# Searching for Tcl Modules. Defines a procedure, declares it as the primary
|
||||||
|
# command for finding packages, however also uses the former 'package unknown'
|
||||||
|
# command as a fallback.
|
||||||
|
#
|
||||||
|
# Locates all possible packages in a directory via a less restricted glob. The
|
||||||
|
# targeted directory is derived from the name of the requested package, i.e.
|
||||||
|
# the TM scan will look only at directories which can contain the requested
|
||||||
|
# package. It will register all packages it found in the directory so that
|
||||||
|
# future requests have a higher chance of being fulfilled by the ifneeded
|
||||||
|
# database without having to come to us again.
|
||||||
|
#
|
||||||
|
# We do not remember where we have been and simply rescan targeted directories
|
||||||
|
# when invoked again. The reasoning is this:
|
||||||
|
#
|
||||||
|
# - The only way we get back to the same directory is if someone is trying to
|
||||||
|
# [package require] something that wasn't there on the first scan.
|
||||||
|
#
|
||||||
|
# Either
|
||||||
|
# 1) It is there now: If we rescan, you get it; if not you don't.
|
||||||
|
#
|
||||||
|
# This covers the possibility that the application asked for a package
|
||||||
|
# late, and the package was actually added to the installation after the
|
||||||
|
# application was started. It shoukld still be able to find it.
|
||||||
|
#
|
||||||
|
# 2) It still is not there: Either way, you don't get it, but the rescan
|
||||||
|
# takes time. This is however an error case and we dont't care that much
|
||||||
|
# about it
|
||||||
|
#
|
||||||
|
# 3) It was there the first time; but for some reason a "package forget" has
|
||||||
|
# been run, and "package" doesn't know about it anymore.
|
||||||
|
#
|
||||||
|
# This can be an indication that the application wishes to reload some
|
||||||
|
# functionality. And should work as well.
|
||||||
|
#
|
||||||
|
# Note that this also strikes a balance between doing a glob targeting a
|
||||||
|
# single package, and thus most likely requiring multiple globs of the same
|
||||||
|
# directory when the application is asking for many packages, and trying to
|
||||||
|
# glob for _everything_ in all subdirectories when looking for a package,
|
||||||
|
# which comes with a heavy startup cost.
|
||||||
|
#

# We scan for regular packages only if no satisfying module was found.
