* Fix #3155 - prevent error when using two matching regex in cascadeBrice Figureau2010-02-171-9/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following manifest: case $var { /match/: { if $var =~ /matchagain/ { } } } is failing because the "=~" operators when matching sets an ephemeral variable in the scope. But the case regex also did it, and since they both belong to the same scope, and Puppet variables are immutables, the scope raises an error. This patch fixes this issue by adding to the current scope a stack of ephemeral symbol tables. Each new match operator or case/selector with regex adds a new scope. When we get out of the case/if/selector structure the scope is reset to the ephemeral level we were when entering it. This way the following manifest produces the correct output: case $var { /match(rematch)/: { notice("1. \$0 = $0, \$1 = $1") if $var =~ /matchagain/ { notice("2. \$0 = $0, \$1 = $1") } notice("3. \$0 = $0, \$1 = $1") } } notice("4. \$0 = $0") And the output is: 1. $0 = match, $1 = rematch 2. $0 = matchagain, $1 = rematch 3. $0 = match, $1 = rematch 4. $0 = Signed-off-by: Brice Figureau <brice-puppet@daysofwonder.com>
* TypeCollection now supports namespace arraysLuke Kanies2010-02-171-12/+3
| | | | | | | | | We previously only supported a single namespace when searching for resource types et al, but the whole system actually relies on an array of namespaces and search paths, so this adds that functionality all the way down, as it were.

* Renaming Parser::ResourceType to Resource::TypeLuke Kanies2010-02-171-2/+2
| | | | | | | | | | Basically, these classes (ResourceType and ResourceTypeCollection) don't really belong in Parser, so I'm moving them to the Resource namespace. This will be where anything RAL-related goes from now on, and as we migrate functionality out of Puppet::Type, it should go here. Signed-off-by: Luke Kanies <luke@reductivelabs.com>
* All non-transient parser references are goneLuke Kanies2010-02-171-7/+10
| | | | | | | | | We now use references to the ResourceTypeCollection instances through the environment, which is much cleaner. The next step is to remove the Interpreter class. Signed-off-by: Luke Kanies <luke@reductivelabs.com>

* Fix #2389 - Enhance Puppet DSL with HashesBrice Figureau2010-02-171-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bring a new container syntax to the Puppet DSL: hashes. Hashes are defined like Ruby Hash: { key1 => val1, ... } Hash keys are strings, but hash values can be any possible right values admitted in Puppet DSL (ie function call, variables access...) Currently it is possible: 1) to assign hashes to variable $myhash = { key1 => "myval", key2 => $b } 2) to access hash members (recursively) from a variable containing a hash (works for array too): $myhash = { key => { subkey => "b" }} notice($myhash[key][subjey]] 3) to use hash member access as resource title 4) to use hash in default definition parameter or resource parameter if the type supports it (known for the moment). It is not possible to string interpolate an hash access. If it proves to be an issue it can be added or work-arounded with a string concatenation operator easily. It is not possible to use an hash as a resource title. This might be possible once we support compound resource title. Unlike the proposed syntax in the ticket it is not possible to assign individual hash member (mostly to respect write once nature of variable in puppet).

* Move scope parenting & class_scope from Compiler to ScopeMarkus Roberts2010-02-171-11/+30
| | | | | | | | | | | | | | | | This refactor fixes about a quarter of the test failures on master and (I hope) will simplify some of the integration issues on the testing branch. It is my best guess at The Right Thing To Do (or at least a step in that direction) but I could be persuaded otherwise. The basic idea is to take responsibility for maintaining scope hierarchy and class_name -> class_scope mapping out of the compiler class and put it in the scope class where it arguably belongs. To maintain the semantics, class scopes are all tracked by the "top level" scope, though this could be relaxed if the nesting semantics were ever needed. If this winds up being the right thing to do, related routines (e.g. newscope) should be sorted out as well.
* Fixing tests broken by caching autoload resultsLuke Kanies2009-08-021-1/+1
| | | | | | | | | These tests tried to load something, verified the loads didn't work, and then created the thing to load. This is a bit silly, so I just removed those sections of the tests. Signed-off-by: Luke Kanies <luke@madstop.com>

| | | | | | | | | | Those variables have been created to be short lived and used mainly to define temporary special variables. They do not persist after a call to unset_ephemeral_var. Also Scope#set_ephemeral_from can be used to promote a regexp MatchData to ephemeral values. Signed-off-by: Brice Figureau <brice-puppet@daysofwonder.com>
* Switching to LoadedCode from ASTSetLuke Kanies2009-07-051-6/+6

* Add an append (+=) variable operator:Brice Figureau2008-09-211-5/+21
| | | | | | | | | | | | | | | | | | | The append variable operator can be used to append something to a variable defined in a parent scope, containing either a string or an array. The main use is to append array elements in classes to a variable globally defined in a node. Example: $ssh_users = ['brice', 'admin1'] class backup { $ssh_users += ['backup_operator'] ... } Signed-off-by: Brice Figureau <brice-puppet@daysofwonder.com>

* Changing the name of the Compile class to Compiler,Luke Kanies2008-02-111-8/+8
| | | | | since it's stupid to have a class named after a verb.
* More AST refactoring -- each of the code wrapping classesLuke Kanies2008-02-081-0/+5
| | | | | | | | | | | just returns a resource from its evaluate() method, and all of the work is done in the evaluate_code method. This makes the code cleaner, because it means 1) evaluate() has the same prototype as all of the other AST classes, 2) evaluate() is no longer called indirectly through the Parser Resource class, and 3) the classes themselves are responsible for creating the resources, rather than it being done in the Compile class.

* We now have a real configuration object, as a subclass of GRATR::Digraph, ↵Luke Kanies2007-09-041-44/+1
| | | | that has a resource graph including resources for the container objects like classes and nodes. It is apparently functional, but I have not gone through all of the other tests to fix them yet. That is next.
* More refactoring. I have removed a few more extraneous methods from Scope, ↵Luke Kanies2007-09-031-51/+20
| | | | mostly just pointing directly to the compile, and I have begun (but commented out) the move to having resources to model each of the classes and nodes, in addition to the definitions. This will, again, enable a real Configuration object, and it will enable class versioning and similar features.

* All language tests now pass. I expect there are other failures elsewhere, ↵Luke Kanies2007-08-201-3/+3
| | | | but I want to commit this before delving into them. My method for fixing the tests was to do as little as possible, keeping the tests as bad or as good as they were before I started. Mostly this was about changing references to the interpreter into references to the parser (since that is where the new* methods are now for ast containers) and then dealing with the new config object and its relationship to scopes.
* The first pass where at least all of the snippet tests pass. I have ↵Luke Kanies2007-08-201-47/+28
| | | | unfortunately had to stop being so assiduous in my rewriting of tests, but I am in too much of a time crunch to do this "right". The basic structure is definitely in place, though, and from here it is a question of making the rest of the tests work and hopefully writing some sufficient new tests, rather than making the code itself work.
* The new parser configuration object works now,Luke Kanies2007-08-161-137/+12
| | | | | | | | | | | | | | but the rest of the compiling process is hosed (although the parser itself should still be fine). The configuration object is unifying a lot of work that was scattered around either the interpreter or the scopes, and it simplifies the whole system. However, its new simplicity has made the complexity of the rest of the system that much more apparent, and I am resolved to fixing the system rather than hacking it sufficiently to just make it work.
* An intermediate commit in the work towards adding multi-environment support.Luke Kanies2007-08-141-182/+40
| | | | | | | | This has required splitting the interpreter up considerably, which is much cleaner but is a large project. There is now a 'nodes' handler, but it is currently non-functional, although all the support structure is there. It just needs to have the individual methods fleshed out, and it needs to be connected to the 'facts' handler.
