# dsc topic
Pull, push, and sync individual topics as local Markdown files. Also tag/untag topics.
## dsc topic pull
```
dsc topic pull <discourse> <topic-id> [<local-path>]
```
Pulls the specified topic into a local Markdown file.
If `<local-path>` is omitted, the topic is written to a new file in the current directory (named from the topic title). Directories are created as needed.
## dsc topic push
```text
dsc topic push <discourse> <topic-id> <local-path>
```
Pushes the local Markdown file up to the specified topic, updating it with the file contents.
## dsc topic sync
```
dsc topic sync <discourse> <topic-id> <local-path> [--yes]
```
Intelligently syncs the topic with the local Markdown file, using the most recently modified version as the source of truth.
Timestamps of both copies are shown before proceeding. Pass `--yes` (or `-y`) to skip the confirmation prompt.
## dsc topic reply
```text
dsc topic reply <discourse> <topic-id> [<local-path>]
```
Posts a new reply at the end of the topic. Reads from `<local-path>` if given, otherwise from stdin (equivalent to passing `-`).
Examples:
```bash
dsc topic reply myforum 1525 ./note.md
## dsc topic new
```text
dsc topic new <discourse> <category-id> --title <title> [<local-path>]
```
Creates a new topic in the given category with the specified title. Reads the body from `<local-path>` if given, otherwise from stdin.
Examples:
```bash
dsc topic new myforum 42 --title "Release notes" ./notes.md
## dsc topic tag
```text
dsc topic tag <discourse> <topic-id> <tag>
```
Adds the given tag to the specified topic, preserving any existing tags. No-op (and prints a message) if the topic already has the tag. Supports `--dry-run` (`-n`).
## dsc topic untag
```text
dsc topic untag <discourse> <topic-id> <tag>
```
Removes the given tag from the specified topic, leaving the others intact. No-op if the tag isn't present. Supports `--dry-run`.
```bash
# Tag every search hit with "triage"
dsc search myforum "status:open category:bugs" --format json \
| jq -r '.[].id' \
| xargs -I{} dsc topic tag myforum {} triage
# Preview removal without committing
dsc -n topic untag myforum 1525 archived
```
