An object with the metadata flag `:displace` set signals that, if a merge
conflict appears, this object is to be discarded. Likewise, `^:replace` signals
that this object should be kept in a merge conflict.
However, previous functionality only tested if the right element had the
`:replace` flag, or if the left element had the `:displace` flag. This commit
resolves this by checking whether the left element has a `:replace` flag and the
right element has a `:displace` flag, and handles accordingly to the semantics
explained in the previous paragraph.
Whenever two elements where both has the `:displace` flag is merged, the
leftmost is picked, and their metadata is merged. Likewise for the `:replace`
flag. The elements will not lose their `:displace` and `:replace` flags, as they
have not really been preferred over another element.
The `nil?` tests have been placed at the top to reflect that nil is the lack of
a value, not a value itself. As such, elements will not be "preferred" or
"discarded" over nil/nothing.
For "important" events, aether gives us enough info to figure
out which repo it is happening from. Lets use it instead
of trying to match from project data.
Previously matching from the project data would be incorrect
and output failures or not output anything for transative repos.
Previously the output for downloading files would just say "failed to find".
Instead output the fact checksums were invalid, and from which repository.
Removes the task to be run residing within a project's metadata (inside
:without-profiles) in addition to the original map, in order to prevent
"with-profile" from reviving already used aliases.
This makes it so that a selector such as :only can prevent unnecessary loading
of namespaces that they aren't going to work on. It is a way for a selector
that knows which namespaces it will touch by the selector's arguments and the
namespace names themselves to not have to load all namespaces.
This commit also fixes a bug introduced by a recent pull request where
'namespaces' could not be resolved. Per discussion with technomancy, provided a
default test selector *always*.
This allows for other directories to be used for the automatic
repository tagging. This is useful for repositories that contain
multiple projects, such as leiningen-core and leiningen, so that both
will have the correct repository tag information in their pom.xml.
There was a good reason we couldn't support this in earlier versions
of Leiningen, but it escapes me now. Perhaps it doesn't work on old
JDKs or there are platform-specific issues or something?
This is accomplished with the :reduce metadata, which specifies the
reduce function to use when merging. This allows us to merge
dependencies and repositories deeply like other structures. Note that
dependencies are transformed into a map before they are merged and then
transformed back into a vector.
Also change the way that collections are merged. They used to be merged
by taking the right collection and prepending it to the left collection.
This behavior was needed for :*-paths in defproject, but it is not an
obvious default. Now, the default is to append the right collection, but
the :prepend metadata can be used to tell meta-merge to prepend instead.
By default, :source-paths, :resource-paths and :test-paths have :prepend
set to true.
This is a list of all named profiles that have been merged in, after
following composite profile. This is different from :included-profiles
which is the list of profiles before composite profiles have been
expanded.
* namespaced keywords to control lookup of credentials in env vars
* using a vector to define a number of credential sources to be checked in series
(gh-768)
Showing every failed repo lookup is bad for users.
They see the failure and get confused.
Hook up a custom listener that has the following behavior:
1. success -> print out artifact name, size, and repository name
2. failure -> ignore unless it is the last repo, then print out failure
message with artifact name.
Fixes#610.
use concat instead of merge to merge values, :plugin-repositories and :repositories are lists again
with merge you will end up with a value for :repositories like [[repo {:url url}] ([pluginrepo {:url url}])]
instead of [[repo {:url url}] [pluginrepo {:url url}]]
On some platforms, eg. Mac, it may be more desirable to use an executable other
than 'gpg' for signing and encryption, and it may not be possible to symlink to
'gpg'. This allows the gpg executable used in lein to be specified via LEIN_GPG.
You can use ~/.lein/leinrc or ~/.leinrc to set LEIN_GPG by adding
'export LEIN_GPG=your-gpg' to either of those files.
On a coworker's Mac, the default file encoding was apparently
MacRoman. The -Dfile.encoding=UTF-8 that's in the lein shell script
wasn't being propogated to subprocesses which caused rage and the
replacement character.
Don't call set-profiles from leiningen.core.project/read because it
calls load-middleware, and we want to wait to do that for the first time
in init-project. To solve this, I added init-profiles which is called by
both read and set-profiles.
Also clean up init-project and move code duplicated in set-profiles into
activate-middleware. We now always load hooks and certificates when
activating middleware, and load-certificates is actually called twice in
the course of init-project. To make sure load-certificates is
idempotent, we memoized leiningen.core.ssl/register-scheme.
Both now expect a full var, though hooks will fall back to activate in
the provided namespace for compatibility.
Also, use the following convention for plugin auto hooks and middleware:
- Assuming your plugin is called lein-config
- Put hooks you want auto-loaded in lein-config.plugin/hooks
- Put middleware you want auto-applied in lein-config.plugin/middleware
Previously, you could not unmerge composite profiles. So, if the
currently active profiles were [:default], which is a composite of
[:dev :user :base], then (unmerge-profiles project :dev) would do
nothing. To fix this, we have to keep track of both :included-profiles
and :excluded-profiles.
I also combined apply-profiles and reset-profiles into a single function
called reset-profiles with an optional excluded-profiles argument and
renamed apply-profiles-raw to apply-profiles.
