The downside is that less options are not supported. +But you can circumvent this by either using the LESS environment variable, or by running `ccat file1 file2|less --opts`. +In the latter form, the file contents will be concatenated and presented by less as a single file. ## Requirements diff --git a/plugins/colorize/colorize.plugin.zsh b/plugins/colorize/colorize.plugin.zsh index 8eede9a94..b8790f260 100644 --- a/plugins/colorize/colorize.plugin.zsh +++ b/plugins/colorize/colorize.plugin.zsh @@ -1,5 +1,6 @@ # easier alias to use the plugin alias ccat='colorize_via_pygmentize' +alias cless='colorize_via_pygmentize_less' colorize_via_pygmentize() { if !
