It is sometimes useful to remember the configuration for every tag, instead of having a single configuration for all tags. Add a command line option to pick per-tags, Then keep the available configurations in a HashMap and pick the right one for user_command and layout. --- v1: https://lists.sr.ht/~novakane/public-inbox/patches/50615 Changes: Applied feedback src/main.zig | 120 +++++++++++++++++++++++++++++++-------------------- 1 file changed, 73 insertions(+), 47 deletions(-) diff --git a/src/main.zig b/src/main.zig index f0298c7..ac5a533 100644 --- a/src/main.zig +++ b/src/main.zig @@ -40,6 +40,7 @@ const usage = \\ -h Print this help message and exit. \\ -version Print the version number and exit. \\ -no-smart-gaps Disable smart gaps + \\ -per-tag Remember configuration per tag \\ \\ The following commands may also be sent to rivercarro at runtime: \\ @@ -86,6 +87,7 @@ const Config = struct { main_count: u31 = 1, main_ratio: f64 = 0.6, width_ratio: f64 = 1.0, + per_tag: bool = false, };
