Copy bibtex to store it in `$BIB`. 34 | 35 | `PDF`: 36 | 37 | - Choose pdf file in `$BIB_PDF_PATH`. 38 | - If the metadata contain doi, then generate bibtex. 39 | - If the metadata contain title or can extract some text, then search on [Crossref](https://search.crossref.org/), and copy doi to generate bibtex. 40 | - If you cannot find doi in crossref, copy any text other than doi, and then `dmenubib` will search on [Google scholar](https://scholar.google.com/). Copy bibtex to store it in `$BIB`. 41 | 42 | ### `REF` to Get BibTeX label for reference 43 | 44 | Choose the criterion to search in `$BIB`. Copy the label of chosen bibtex to clipboard. 45 | 46 | ### `OPN` to open corresponding pdf file 47 | 48 | Choose the criterion to search in `$BIB`. Open the corresponding pdf in `$BIB_PDF_PATH`. 49 | 50 | ### `PDF` to Manually Rename and encode metadata into pdf 51 | 52 | Choose pdf files, and choose which bibtex entry to generate metadata. 53 | 54 | PDF will be renamed as bibtex label, and attached with Title, Author, and doi metadata. 55 | 56 | ### `AUO` to Automatically rename and encode metadata into pdf 57 | 58 | Automatically go through all pdf files in `$BIB_PDF_PATH`, check whether correctly named. `Dmenubib` will generate a list of unmatched pdf files, and allow manual rename and encode metadata using `PDF` function. 59 | 60 | **Caveat: `AUO` update pdf based on pdf filename. So if you update your bibtex and want to update metadata, use `PDF` instead.** 61 | 62 | ## `NTE` to write notes for each reference 63 | 64 | Store the notes for each paper as markdown file in `$BIB_PDF_PATH/Notes`. 65 | 66 | Each `.md` file is named after the bibtex label in `$BIB`. 67 | 68 | -------------------------------------------------------------------------------- /dmenubib: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | BIB="$BIB" 4 | BIB_PDF_PATH="$BIB_PDF_PATH" 5 | BIB_NOTE_PATH="$BIB_PDF_PATH/Notes" 6 | BIB_GENERIC_FONT=Monospace-15 7 | BIB_NOTIF_FONT=Monospace-25 8 | BIB_GENERIC_COLOR=#005577 9 | BIB_SER="SER - Search BibTeX on Internet" 10 | BIB_REF="REF - Get BibTeX label for reference" 11 | BIB_OPN="OPN - Open corresponding pdf file based on BibTeX" 12 | BIB_PDF="PDF - Manually Rename and encode metadata into pdf" 13 | BIB_AUO="AUO - Automatically rename and encode metadata into pdf" 14 | BIB_NTE="NTE - Write markdown notes on references" 15 | BIBACTLIST="$(printf '%s\n' "$BIB_SER" "$BIB_REF" "$BIB_OPN" "$BIB_PDF" "$BIB_AUO" "$BIB_NTE")" 16 | nl=' 17 | ' 18 | act="placeholder" 19 | doi_regex='(https://doi.org/)?10\.[0-9]{4}[0-9.]*/[^[:space:]]*' 20 | 21 | [ ! -d "$BIB_NOTE_PATH" ] && mkdir "$BIB_NOTE_PATH" 22 | 23 | . dmenubib-menu 24 | . dmenubib-search 25 | . dmenubib-refer 26 | . dmenubib-pdfmeta 27 | . dmenubib-open 28 | 29 | CheckDeps () { 30 | depcount=0 31 | for CurDep in "$@";
