One way to get stdout from files in DDS while debugging is to log messages to a file. You can add a method such as:
void _fileLog(String message) {
final file = File('/tmp/dds.log');
if (!file.existsSync()) {
file.createSync();
}
file.writeAsStringSync(
'''
$message
''',
mode: FileMode.append,
flush: true,
);
}
Then you can call _fileLog('some print debugging message')
, and the log message will be written to a temp file.
To get logging output in real time, run tail -f /tmp/dds.log
.
If you do not need to build the Dart SDK to test your changes, you
can add a dependency_overrides
for devtools_shared
that points to your
local devtools_shared
directory from path:
dependency_overrides:
devtools_shared:
path: ../../relative_path_to/devtools/packages/devtools_shared
If you do need to build the Dart SDK to test your changes, in addition
to adding the dependency override above, you will need to add a symbolic link
to your local devtools_shared
directory:
From the sdk/
directory, run:
rm -rf third_party/devtools/devtools_shared;
ln -s /absolute_path_to/devtools/packages/devtools_shared third_party/devtools/devtools_shared
WARNING: do not run gclient sync -D
while the symbolic link is present,
as this could cause issues with your local devtools_shared
code.
To delete the symbolic link after you are done with development, run:
rm -rf third_party/devtools/devtools_shared
