## Features
- Open the editor of your choice for editing.
- Filter based on the category of the question.
- Perform a fuzzy search.
- Test and submit the code.
- Modify the test case.
- Automatically get cookies to eliminate the need for manual copying from the browser(support for a few specific browsers and platforms only,as adapting to various browsers and platforms can be complicated).
## Install
**Linux** Option dependencies(a implement `SecretService` service Application)：
- `gnome-keyring`
- `kwallet`
- `KeePassXC`
- `libsecret`
---
- stable
```shell
cargo install lcode
```
- nightly
```shell
cargo install --git=https://github.com/saying121/leetcode-cn-en-cli.git --force
```
## Useage
Generate configuration, manual modification of the configuration is also possible,
and it will be automatically generated at runtime.
Without -c, it will be generated in English.
```shell
lcode gencon -c
```
Synchronize basic data first.
```shell
lcode sync
```
View the documentation for assistance.
```shell
lcode -h
```
Begin selecting a question.
```shell
lcode fzy <edit>
```

## Configuration
The configuration located
- Linux: `~/.config/leetcode-cn-en-cli/config.toml`
- macos: `~/.config/leetcode-cn-en-cli/config.toml`
- Windows: `|C:\Users\Alice\AppData\Roaming`
The code default located
- Linux: `$HOME/.local/share/leetcode-cn-en-cli/`
- macOS: `$HOME/Library/Application Support/leetcode-cn-en-cli`
- Windows: `C:\Users\Alice\AppData\Local\leetcode-cn-en-cli`
default:
```toml
translate = false
column = 4
num_sublist = 10
page_size = 25
editor = ["vim"]
lang = "rust"
code_dir = "/home/user/.local/share/leetcode-cn-en-cli"
url_suffix = "com"
[support_lang]
langs = ["rust", "bash", "c", "cpp", "csharp", "golang", "java", "javascript", "kotlin", "mysql", "php", "python", "python3", "ruby", "scala", "swift", "typescript", "racket", "erlang", "elixir", "dart"]
[cookies]
csrf = ""
session = ""
```
### Important
**First, login leetcode in browser for generate cookies**
`browser` can fill in `chrome`, `edge`, `firefox`, `librewolf`.
Now support this browser, and just test in Linux.(firefox should support three systems)
If use the section，be careful not to clear cookies when closing the browser.
`[cookies]` section
- If the two subfields are not empty,use the content filled by the user.
And not use other method to get cookies。
- Fill in manually：
Press <kbd>F12</kbd> on the browser's `leetcode.com/com` page,
Find the **Cookie** field, copy the **`csrftoken`=\<content\>;**
and **`LEETCODE_SESSION`=\<content\>;** sections inside it into the configuration.
- If user filled `browser` , will try to use the browser to get cookies.
- If neither of the above two items is filled in,
and then use this order _firefox_ -> _edge_ -> _chrome_ -> _librewolf_ try to get cookies.
### Here are the explanations for each field
Fill in `false` or `true`, default is `false`.
If `true` is chosen, the translated content will be used to display the question details.
```toml
translate = false
```
---
When retrieving the **submissionlist**, how many columns should be displayed.
```toml
column = 4
```
---
How many recent entries of the submissionlist information should be displayed.
```toml
num_sublist = 10
```
---
How many questions should be displayed at once when interactively selecting a question.
```toml
page_size = 25
```
---
Fill in your editor, it will attempt to retrieve it from the environment variables EDITOR and VISUAL,
otherwise it will default to vim.
```toml
editor = ["vim"]
```
You can add additional parameters at the end.
```toml
editor = ["vim", "--noplugin"]
```
---
Set your selected programming language.
```toml
lang = "rust"
```
---
Set the location for storing code and test cases.
```toml
code_dir = "/home/user/.local/share/leetcode-cn-en-cli"
```
You can also write it like this, starting with `~`
```toml
code_dir = "~/.local/share/leetcode-cn-en-cli"
```
---
Fill in `com` or `cn`, for set `leetcode.com` or `leetcode.cn`.
```toml
url_suffix = "com"
```
---
```toml
[support_lang.rust]
start = "//start/"
end = "//end/"
inject_start = ""
inject_end = "struct Solution;\n\nfn main() {\n println!(\"{:#?}\", Solution::function());\n}"
[support_lang.c]
...
```
will from this generate code template.
can write multi line,`"""..."""` or `'''...'''`：
```toml
inject_end = """struct Solution;
fn main() {
println!("{:#?}", Solution::function());
}"""
```
Example: 108
```rust
// Definition for a binary tree node.
#[derive(Debug, PartialEq, Eq)]
pub struct TreeNode {
pub val: i32,
pub left: Option<Rc<RefCell<TreeNode>>>,
pub right: Option<Rc<RefCell<TreeNode>>>,
}
impl TreeNode {
#[inline]
pub fn new(val: i32) -> Self {
TreeNode {
val,
left: None,
right: None,
}
}
}
//start/
// ...something
use std::cell::RefCell;
use std::rc::Rc;
impl Solution {
pub fn sorted_array_to_bst(mut nums: Vec<i32>) -> Option<Rc<RefCell<TreeNode>>> {
let len = nums.len();
if len == 0 {
return None;
}
let root = Rc::new(RefCell::new(TreeNode::new(nums[len / 2])));
let mut right = nums.split_off(len / 2);
right.remove(0);
root.borrow_mut().left = Self::sorted_array_to_bst(nums);
root.borrow_mut().right = Self::sorted_array_to_bst(right);
Some(root)
}
}
//end/
struct Solution;
fn main() {
println!(
"{:#?}",
Solution::sorted_array_to_bst(vec![-10, -3, 0, 5, 9])
);
}
```
When submit to leetcode, only content between `support_lang.rust.start`
and `support_lang.rust.start` will be uploaded.
If don't have this will uploaded all content.

Please check the Tui interface for specific keymap information.
## Fuzzy Search
fuzzy search tui and cli implement is same，in cli paid only is true ，in tui also can input `true`/`P.O.: tru` for filter.
## Database error
Since `leetcode.cn` and `leetcode.com` obtain different information, database errors may occur after switching between _cn_ and _com_.
At this time, please re-synchronize the data `lcode sync -f` (recommand), or press <kbd>S</kbd> on a tab in the Tui interface.
