From 22336834109a1659069acdfb1dfeb324206a9fc9 Mon Sep 17 00:00:00 2001 From: Tilmann Meyer Date: Mon, 28 Sep 2020 22:38:50 +0200 Subject: [PATCH] feat: add error messaging (#1576) This creates a custom logger for the log crate which logs everything to a file (/tmp/starship/session_$STARSHIP_SESSION_KEY.log) and it logs everything above Warn to stderr, but only if the log file does not contain the line that should be logged resulting in an error or warning to be only logged at the first starship invocation after opening the shell. --- CONTRIBUTING.md | 2 +- Cargo.lock | 58 +----------- Cargo.toml | 4 +- docs/config/README.md | 15 +++ src/config.rs | 14 +-- src/configs/custom.rs | 6 +- src/configure.rs | 1 - src/init/starship.bash | 3 + src/init/starship.fish | 3 + src/init/starship.ion | 3 + src/init/starship.ps1 | 3 + src/init/starship.zsh | 3 + src/lib.rs | 1 + src/logger.rs | 112 +++++++++++++++++++++++ src/main.rs | 15 ++- src/modules/aws.rs | 2 +- src/modules/battery.rs | 2 +- src/modules/cmd_duration.rs | 6 +- src/modules/directory.rs | 2 +- src/modules/dotnet.rs | 2 +- src/modules/git_branch.rs | 2 - src/modules/git_status.rs | 14 +-- src/modules/hg_branch.rs | 2 - src/modules/hostname.rs | 2 +- src/utils.rs | 2 +- starship_module_config_derive/src/lib.rs | 6 +- 26 files changed, 188 insertions(+), 97 deletions(-) create mode 100644 src/logger.rs diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index 1583064c..8277afe8 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -72,7 +72,7 @@ pub fn module<'a>(context: &'a Context) -> Option> { ## Logging -Debug logging in starship is done with [pretty_env_logger](https://crates.io/crates/pretty_env_logger). +Debug logging in starship is done with our custom logger implementation.
