为org-capture-templates添加补全

emacs
ledger, org

  1. org-capture-templates提供了 %^{prompt) 默认补全的功能， | 后紧跟默认值即可

    这种方法有一个缺陷，需要提前定义ledger中的好各种账户类别。 

    ("fi" "Income" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\tAssets:%^{Account|招商银行|支付宝|微信钱包|现金|理财账户:朝朝盈|理财账户:微众银行}    %^{Amount} CNY\n\t\t\tIncome:%^{Income|工资|报销|私活|利息|房租|转账}")
("fe" "Expenses" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\tExpenses:%^{Expenses|宠物|生活消费:三餐|生活消费:水果|交通:打车费|电子设备|学习|住房|服饰:|请客|转账|请客|送礼}    %^{Amount} CNY\n\t\t\tAssets:%^{Account|招商银行|支付宝|微信钱包|现金|理财账户:朝朝盈|理财账户:微众银行}")
("fl" "Liabilities" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\tExpenses:%^{Account|宠物|生活消费:三餐|生活消费:水果|交通:打车费|电子设备|学习|住房|服饰:|请客|转账|请客|送礼}    %^{Amount} CNY\n\t\t\tLiabilities:%^{LAccount|花呗|借呗|白条}")
("ft" "Transaction" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\tAssets:%^{AccountIn|招商银行|支付宝|微信钱包|现金|理财账户:朝朝盈|理财账户:微众银行}    %^{Amount} CNY\n\t\t\tAssets:%^{AccountOut|招商银行|支付宝|微信钱包|现金|理财账户:朝朝盈|理财账户:微众银行}")

  2. 新的解决方案

    先从ledger文件中提取所有的账户类别保存到固定文件中，使用org-capture中的 %(EXP) 模板展开，把结果替换到 %^{prompt) 的补全列表中。

    • 提取列表 

      # -*- coding:utf-8 -*-
import re


def extract_history_from_ledger_file(ledger_file_path):
    """
    从ledger文件中提取输入历史
    """
    match = r"(^Assets|Expense|Liabilities|Income)"
    find = r"([A-Z]+[:\S]+)"
    history = []
    with open(ledger_file_path, 'r') as f:
        content = f.readlines()
        for i in content:
            if not re.match(match, i.strip()):
                continue
            result = re.findall(find, i.strip())
            if result:
                if result[0].decode("utf-8") not in history:
                    history.append(result[0].decode("utf-8"))
    with open("/Users/chenxuesong/.ledger/.Assets", 'w') as his:
        for i in history:
            if i.startswith("Assets"):
                his.write(i.encode("utf-8"))
                his.write("\n")
    with open("/Users/chenxuesong/.ledger/.Liabilities", 'w') as his:
        for i in history:
            if i.startswith("Liabilities"):
                his.write(i.encode("utf-8"))
                his.write("\n")
    with open("/Users/chenxuesong/.ledger/.Expense", 'w') as his:
        for i in history:
            if i.startswith("Expense"):
                his.write(i.encode("utf-8"))
                his.write("\n")
    with open("/Users/chenxuesong/.ledger/.Income", 'w') as his:
        for i in history:
            if i.startswith("Income"):
                his.write(i.encode("utf-8"))
                his.write("\n")


if __name__ == '__main__':
    extract_history_from_ledger_file("2019-finance.ledger")

    • 自定义函数读取列表，并转换 

      (defun chenxuesong-read-lines (filePath)
  "Return a list of lines of a file at filePath."
  (with-temp-buffer
    (insert-file-contents filePath)
    (split-string (buffer-string) "\n" t)))
(defun prompt-completion-assets ()
  (string-join (chenxuesong-read-lines "/Users/chenxuesong/.ledger/.Assets") "|"))
(defun prompt-completion-income ()
  (string-join (chenxuesong-read-lines "/Users/chenxuesong/.ledger/.Income") "|"))
(defun prompt-completion-liabilities ()
  (string-join (chenxuesong-read-lines "/Users/chenxuesong/.ledger/.Liabilities") "|"))
(defun prompt-completion-expense ()
  (string-join (chenxuesong-read-lines "/Users/chenxuesong/.ledger/.Expense") "|"))

    • 重新修改配置 

      ("f" "Ledger")
("fi" "Income" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\t%^{Account|%(prompt-completion-assets)}    %^{Amount} CNY\n\t\t\t%^{Income|%(prompt-completion-income)}")
("fe" "Expenses" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\t%^{Expenses|%(prompt-completion-expense)}    %^{Amount} CNY\n\t\t\t%^{Account|%(prompt-completion-assets)}")
("fl" "Liabilities" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\t%^{Account|%(prompt-completion-expense)}    %^{Amount} CNY\n\t\t\t%^{LAccount|%(prompt-completion-liabilities)}")
("ft" "Transaction" plain (file (format "~/org/%s-finance.ledger" (format-time-string "%Y")))
 "\n\t%(org-read-date) * %^{Payee}\n\t\t\t%^{AccountIn|%(prompt-completion-assets)}    %^{Amount} CNY\n\t\t\t%^{AccountOut|%(prompt-completion-assets)}")
