The scoping rules when creating or updating a variable are: -- If a variable is explicitly set to a scope (universal, global or local), that setting will be honored. If a variable of the same name exists in a different scope, that variable will not be changed. +- When a scope is explicitly given, it will be used. If a variable of the same name exists in a different scope, that variable will not be changed. -- If a variable is not explicitly set to a scope, but has been previously defined, the variable scope is not changed. +- When no scope is given, but a variable of that name exists, the variable of the smallest scope will be modified. The scope will not be changed. -- If a variable is not explicitly set to a scope and has not been defined, the variable will be local to the currently executing function. Note that this is different from using the ``-l`` or ``--local`` flag. If one of those flags is used, the variable will be local to the most inner currently executing block, while without these the variable will be local to the function. If no function is executing, the variable will be global. +- As a special case, when no scope is given and no variable has been defined the variable will belong to the scope of the currently executing *function*. Note that this is different from the ``--local`` flag``, which would make the variable local to the current *block*. There may be many variables with the same name, but different scopes. When using a variable, the variable scope will be searched from the inside out, i.e. a local variable will be used rather than a global variable with the same name, a global variable will be used rather than a universal variable with the same name. @@ -829,10 +829,13 @@ The following code will not output anything:: begin # This is a nice local scope where all variables will die set -l pirate 'There be treasure in them thar hills' + set captain Space, the final frontier end echo $pirate # This will not output anything, since the pirate was local + echo $captain + # This will output the good Captain's speech since $captain had function-scope. .. _variables-override: From 66b0fa72aa18f596069d63bf2a0280a3356990a1 Mon Sep 17 00:00:00 2001 From: Fabian Homborg Date: Tue, 31 Mar 2020 17:07:06 +0200 Subject: [PATCH 012/107] Add github actions CI --- .github/workflows/main.yml | 48 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 .github/workflows/main.yml diff --git a/.github/workflows/main.yml b/.github/workflows/main.yml new file mode 100644 index 000000000..a1319548e --- /dev/null +++ b/.github/workflows/main.yml @@ -0,0 +1,48 @@ +name: C/C++ CI + +on: + push: + branches: [ master ] + pull_request: + branches: [ master ] + +jobs: + ubuntu: + + runs-on: ubuntu-latest + + steps: + - uses: actions/checkout@v2 + - name: Install deps + run: | + sudo apt install expect gettext libncurses5-dev libpcre2-dev + - name: cmake + run: | + mkdir build && cd build + cmake .. + - name: make + run: | + make + - name: make test + run: | + make test + + macos: + + runs-on: macos-latest + + steps: + - uses: actions/checkout@v2 + - name: Install deps + run: | + brew install pcre2 + - name: cmake + run: | + mkdir build && cd build + cmake .. + - name: make + run: | + make + - name: make test + run: | + make test From d54609bd6360fea42dad86f148bff8e5ca4f0fee Mon Sep 17 00:00:00 2001 From: Fabian Homborg Date: Tue, 31 Mar 2020 19:34:05 +0200 Subject: [PATCH 013/107] Skip interactive tests on github actions for now Github actions doesn't run this in a terminal, so the `fish -i` tests won't really work.

In vim, tilde toggles the case of the character under the cursor and advances one character. In visual mode, the case of each selected character is toggled, the cursor position moves to the beginning of the selection, and the mode is changed to normal. In fish, tilde capitalizes the current letter and advances one word. There is no current tilde command for visual mode in fish. This patch adds the readline commands `togglecase-letter` and `togglecase-selection` to match the behavior of vim more closely. The only difference is that in visual mode, the cursor is not modified. Modifying the cursor in visual mode would require either moving it in `togglecase-selection`, which seems outside its scope or adding something like a `move-to-selection-start` readline command. --- share/functions/fish_vi_key_bindings.fish | 3 +- src/input.cpp | 2 + src/input_common.h | 2 + src/reader.cpp | 66 +++++++++++++++++++++++ 4 files changed, 72 insertions(+), 1 deletion(-) diff --git a/share/functions/fish_vi_key_bindings.fish b/share/functions/fish_vi_key_bindings.fish index ddfaf6e86..f83bfe0a3 100644 --- a/share/functions/fish_vi_key_bindings.fish +++ b/share/functions/fish_vi_key_bindings.fish @@ -187,7 +187,7 @@ function fish_vi_key_bindings --description 'vi-like key bindings for fish' bind -s --preset -m insert ci backward-jump-till and repeat-jump-reverse and begin-selection repeat-jump kill-selection end-selection repaint-mode bind -s --preset -m insert ca backward-jump and repeat-jump-reverse and begin-selection repeat-jump kill-selection end-selection repaint-mode - bind -s --preset '~' capitalize-word + bind -s --preset '~' togglecase-char forward-char bind -s --preset gu downcase-word bind -s --preset gU upcase-word @@ -291,6 +291,7 @@ function fish_vi_key_bindings --description 'vi-like key bindings for fish' bind -s --preset -M visual -m default X kill-whole-line end-selection repaint-mode bind -s --preset -M visual -m default y kill-selection yank end-selection repaint-mode bind -s --preset -M visual -m default '"*y' "commandline -s | xsel -p;
