How do I increase the capacity of the Eclipse output console?

Even with the "scroll lock" option enabled for the Eclipse console, eventually it overfills and starts auto-scrolling on me.

Is there some way of increasing the capacity of the console so that it stores more lines? I wasn't able to find the option.

Solution 1:

Under Window > Preferences, go to the Run/Debug > Console section, then you should see an option "Limit console output." You can uncheck this or change the number in the "Console buffer size (characters)" text box below.

(This is in Galileo, Helios CDT, Kepler, Juno, Luna, Mars, Neon, Oxygen and 2018-09)

Solution 2:

Open the Windows > Preferences menu.

Expand the Run/Debug > Console preferences.

Set the Console buffer size (characters) to something much bigger. 2147383647 / ~2GB is the upper limit (or 1000000 / ~1MB in older releases). Or just uncheck the Limit console output.

Solution 3:

For CDT users / C/C++ build, also adjust the setting

in Window > Preferences

under C/C++ > Build > Console (!)

(This time in number of lines.)

This also affects the "CDT Global Build Console".
