[![Crates.io](https://img.shields.io/crates/v/mdbook-transcheck.svg)](https://crates.io/crates/mdbook-transcheck)
# Install
```console
$ cargo install mdbook-transcheck
```
# Usage
## Check
The following command checks whether `src` and `tgt` are synchronized.
```console
$ mdbook-transcheck src tgt
```
`src` is the source directory of original mdbook.
`tgt` is the source directory of translated mdbook.
## Fix
The following command applies the differences between `src` and `tgt` to `tgt`.
```console
$ mdbook-transcheck --fix src tgt
```
## Lint
The following command checks whether translated texts satisfy lint rules.
```console
$ mdbook-transcheck --lint src tgt
```
# Configuration
The configuration file is `transcheck.toml`, which is put at the repository root.
```toml
excludes = ["img/"]
[matcher]
enable_code_comment_tweak = true
code_comment_header = "# "
[linter]
enable_emphasis_check = true
enable_half_paren_check = true
enable_full_paren_check = true
```
## root section
| excludes | String Array | [] | Exclude paths which are relative path from source directory |
## `[matcher]` section
| enable_code_comment_tweak | true, false | false | Match code comment without `code_comment_header` |
| code_comment_header | String | `"# "` | |
| keep_markdown_comment | true, false | false | Keep Markdown comment in original |
| markdown_comment_begin | String | `(((` | |
| markdown_comment_end | String | `)))` | |
| similar_threshold | Float | 0.5 | If the ratio which the original and translated lines are matched exceeds `similar_threshold`, the line is judged as *modified*. |
## `[linter]` section
| enable_emphasis_check | true, false | false | Check wether emphasis (`*..*`/`**..**`) has spaces before and after it. |
| enable_half_paren_check | true, false | false | Check wether half-width paren (`()`) has ascii charactors only. |
| enable_full_paren_check | true, false | false | Check wether full-width paren (`()`) has non-ascii charactors. |
# Example
```console
$ mdbook-transcheck ./testcase/original ./testcase/translated
Error: target path is not found
source path: ./testcase/original/missing_file.md
target path: ./testcase/translated/missing_file.md
Error: source line has been modified
source --> ./testcase/original/mismatch_lines.md:5
|
|
target --> ./testcase/translated/mismatch_lines.md:11
|
|
Error: lines has been inserted to the source file
source --> ./testcase/original/mismatch_lines.md:2
|
= hint: The lines should be inserted at ./testcase/translated/mismatch_lines.md:2
Error: lines has been removed from the source file
target --> ./testcase/translated/mismatch_lines.md:4
|
```
# Markdown rule
The translated markdown should follow some rules.
* Keep original lines
* Comment out original lines by `<!--` and `-->`
## Simple example
* original
```markdown
Apple
Orange
Peach
```
* translated
```markdown
りんご
オレンジ
桃
```
The following is NG because `<!-- Apple` and `Peach -->` are not matched with original lines.
```markdown
りんご
オレンジ
桃
```
## Markdown comment
If the original text has markdown commets, the commets should be removed in the translated text because nested comment is not supported.
The differences by removing the comments are ignored by default.
* original
```markdown
Apple <!-- ignore -->
Or<!-- ignore -->ange
Peach
```
* translated
```markdown
りんご
オレンジ
桃
```
If you want to keep the comments, `keep_markdown_comment`, `markdown_comment_begin` and `markdown_comment_end` can be used like below:
```toml
keep_markdown_comment = true
markdown_comment_begin = "((("
markdown_comment_end = ")))"
```
* original
```markdown
Apple <!-- ignore -->
Or<!-- ignore -->ange
Peach
```
* translated
```markdown
りんご
オレンジ
桃
```
## Code block
* original
````markdown
```rust
// comment
let a = b; // comment
```
````
* translated
````markdown
```rust
// comment
// コメント
let a = b; // comment
// コメント
```
````
You can use `# ` to hide the original comment.
`enable_code_comment_tweak` should be `true`, and `code_comment_header` should be `# `.
````markdown
```rust
# // comment
// コメント
let a = b; // comment
// コメント
```
````
You can use `# // ` to hide the original code and comment.
`enable_code_comment_tweak` should be `true`, and `code_comment_header` should be `# // `.
````markdown
```rust
# // // comment
// コメント
# // let a = b; // comment
let a = b; // コメント
```
