Package isolate implements the code to process '.isolate' files to generate '.isolated' files.
doc.go format.go isolate.go utils.go
const IsolatedGenJSONVersion = 1
IsolatedGenJSONVersion is used in the batcharchive json format.
TODO(tandrii): Migrate to batch_archive.go.
const ValidVariable = "[A-Za-z_][A-Za-z_0-9]*"
ValidVariable is the regexp of valid isolate variable name.
func Archive(arch *archiver.Archiver, opts *ArchiveOptions) *archiver.PendingItem
Archive processes a .isolate, generates a .isolated and archive it. Returns a *PendingItem to the .isolated.
IsValidVariable returns true if the variable is a valid symbol name.
ProcessIsolate parses an isolate file, returning the list of dependencies (both files and directories), the root directory and the initial Isolated struct.
func ReplaceVariables(str string, opts *ArchiveOptions) (string, error)
ReplaceVariables replaces any occurrences of '<(FOO)' in 'str' with the corresponding variable from 'opts'.
If any substitution refers to a variable that is missing, the returned error will refer to the first such variable. In the case of errors, the returned string will still contain a valid result for any non-missing substitutions.
type ArchiveOptions struct { Isolate string `json:"isolate"` Isolated string `json:"isolated"` Blacklist stringlistflag.Flag `json:"blacklist"` PathVariables stringmapflag.Value `json:"path_variables"` ExtraVariables stringmapflag.Value `json:"extra_variables"` ConfigVariables stringmapflag.Value `json:"config_variables"` }
ArchiveOptions for archiving trees.
func (a *ArchiveOptions) Init()
Init initializes with non-nil values.
func (a *ArchiveOptions) PostProcess(cwd string)
PostProcess post-processes the flags to fix any compatibility issue.
type ConfigSettings struct { // Files is the list of dependencies. The items use '/' as a path separator. Files []string // Command is the actual command to run. Command []string // ReadOnly describes how to map the files. ReadOnly ReadOnlyValue // IsolateDir is the path where to start the command from. // It uses the OS' native path separator and it must be an absolute path. IsolateDir string }
ConfigSettings represents the dependency variables for a single build configuration.
The structure is immutable.
type Configs struct { // ConfigVariables contains names only, sorted by name; the order is same as in byConfig. ConfigVariables []string // contains filtered or unexported fields }
Configs represents a processed .isolate file.
Stores the file in a processed way, split by configuration.
At this point, we don't know all the possibilities. So mount a partial view that we have.
This class doesn't hold isolateDir, since it is dependent on the final configuration selected. It is implicitly dependent on which .isolate defines the 'command' that will take effect.
LoadIsolateAsConfig parses one .isolate file and returns a Configs instance.
Arguments: isolateDir: only used to load relative includes so it doesn't depend on cwd. value: is the loaded dictionary that was defined in the gyp file. The expected format is strict, anything diverting from the format below will result in error: { 'includes': [ 'foo.isolate', ], 'conditions': [ ['OS=="vms" and foo=42', { 'variables': { 'command': [ ... ], 'files': [ ... ], 'read_only': 0, }, }], ... ], 'variables': { ... }, }
func (c *Configs) GetConfig(cn configName) (*ConfigSettings, error)
GetConfig returns all configs that matches this config as a single ConfigSettings.
Returns nil if none apply.
ReadOnlyValue defines permissions on isolated files.
const ( NotSet ReadOnlyValue = -1 Writable ReadOnlyValue = 0 FilesReadOnly ReadOnlyValue = 1 DirsReadOnly ReadOnlyValue = 2 )
Possible kinds of read only values.
func LoadIsolateForConfig(isolateDir string, content []byte, configVariables map[string]string) ( []string, []string, ReadOnlyValue, string, error)
LoadIsolateForConfig loads the .isolate file and returns the information unprocessed but filtered for the specific OS.
Returns:
command, dependencies, readOnly flag, relDir, error.
relDir and dependencies are fixed to use os.PathSeparator.
func (r ReadOnlyValue) ToIsolated() (out *isolated.ReadOnlyValue)
ToIsolated can be used to convert ReadOnlyValue enum values to corresponding isolated.ReadOnlyValue enum values. It returns nil on errors.
type Tree struct { Cwd string Opts ArchiveOptions }
Tree to be isolated.
