Logseq Diff & Merge:

Block level diff and merge for Logseq

Progress:

- [x] Merge
- [x] Tests
- [x] Consider id::
- [x] Finalize language choice & rewrite - Typescript
- [x] Mldoc port in
- [x] Org-mode support - via Mldoc

Usage:

- Refer to the demo at entry src. yarn dev to run it.
- Returning operations are indexed by the "original block position". For Diff, it's defined by the first (base) branch to diff; For Merge, it's defined by the base branch of the branches to merge.
- The 0 index is reserved for the ops to be inserted before the first base block.
- Ex. the following case would generate an empty [] at 0 index:
base:
``
## hello
- world
- nice
- nice
- bingo
- world
`
branch:
`
## Halooooo
- world
- nice
- nice
- bingo
- world
`
result (notice the empty array at 0 index):
`
Array(7) [ [], (2) […], (1) […], (1) […], (1) […], (1) […], (1) […] ]
`
Reason: no insertion is needed before the first base block.
- The op (DELETE/EQUAL/INSERT) represents the one-to-one correspondence between blocks before and after diff-merge. Equal doesn't mean equal in content, it means that the block is the same block as it was before (e.g., same block UUID)

Strategy:

- Resolve inner block conflict by line if block are shipped with uuid (e.g., id:: in Logseq Markdown)
- Do not execute delete operation if there is any "modified" equal block in the same position from other branches. This is to avoid deleting a block that is modified by other branches.

Dev:

- Experiments: yarn dev
- Build dist: yarn build
- Publish to NPM: yarn publish`
